Description

-17:-46:-38 - Approved: Random-access document model for JSON (JsonDocument) https://github.com/dotnet/corefx/issues/33968

A

All right I know we are live again.

B

um All right today we're talking about what are we talking about when the max's document- wonderful, Jason, okay, don't release it. So whatever do you want to walk us through what you have there? Okay.

C

C

The names that I have we're certainly inspired by our XML types, and so they may be subject to some Jason application by the the idea. Is you can parse something into a thing called jason document it? It is what holds the state of the parse document. It takes a read-only memory and keeps that memory alive and then keeps just preparing for that throughout the time using it, and the only thing you can do to it is dispose, which frees the state that it has mainly needs.

C

Returning to that back to the eraser and ask for the element: is the parent not to call these phones? If you don't call the suppose, you stolen from the area cool instead of a different variable.

D

It's only the you only event the additional buffers like for the database. It rates the space to store that the.

C

Parsing, instead of basically.

D

This post has no effect on anything that could pass into.

C

So as written right here, it accepts a set of reader options. The only computer options has on it right now is the comment handling ass on and I've worked through several scenarios involving. If we let comments be parsed into the document model and every answer is they don't make sense, so it will reject. We accept comments, but it will allow the skipped comments and then Jason reader also accepts a maximum stack depth which currently I don't have here and I could service just because their service repair.

C

Right at that, 30 defaulting to the same.

E

Value and then the three options also default, the default, which is what create events and when.

D

It when it would be setting be on Jason Tony, it's a phenomena parameter to parse parse creates.

C

The reader brings the robot.

A

To NZ in two options.

C

Direct H turn on in the opportunity. That's already we should discuss or change yes, so one one option is right now in Jason reader being what is the maximum depth? That I'm willing to walk into is a value sitting next to the options and then I mention pass on the. Maybe we want to move it into the options.

D

The reason I asked I mean I, don't think we should be complicating the api's for focus.

C

When I originally wrote, this I thought it was part of the options and.

D

Then I found that it was liking. The low-level API I think it's fine to have it this. If we kind of intend you know average dotnet developer, to use it right, then you know, unless we see a very strong reason, you should just write the only policy I see if we can edit later is. Do we feel that.

C

At this level, restricting the parsing depth is a a memory bounding problem from untrusted data I.

F

Believe it is something that is for exposing.

D

F

Limit we have the limit.

D

I'm not saying this, we shouldn't, but is it worth to expose it using ability to control it? Why we won? It is art project.

C

At the 64th of TV, oxidation, America, well doesn't Jason wheeler options also exposed stuff like I, awoke comments. Yeah.

G

Yeah, but if it seems.

C

Like you would still want to take in the office for and over just to be able to for a boy to be able to control all much practicing. Sorry.

D

D

Would not pollute that Paris with more piranha. First.

H

D

That we can initially go, then we have a cabin and honestly.

I

D

What sucks about widows works as well? There's a single XML resource argument.

H

And everything so so either we move the Mantid up to the options parameter and now it's customized for both layers or we set the default here to 54 and don't do it I, don't.

D

Know it's 64 is the right measure.

H

D

To something that basically is between reasonable and somebody starting me right, yeah I.

H

Don't mind moving it match depth or you just read your options, and that way you bet there's not much of an unborn. That's.

F

Probably the right option.

C

Okay, so I'm Jason document, the only thing that you can get is Jason element, so the adjacent element type really you you can think about it as it is a cursor position. All the only thing that actually stores inside itself is which entry in the database that that is held by Jason document is this thing representing, and every action just refers back to interpreting something out of the database. So it is a destructiveness of it is which document that I come from and you can see I'm so.

D

It's basically either element or I mean either JSON object or JSON array or Jason. Poly is an object, array of value or property.

C

It is the union of our various types funds like this, but.

J

C

Root element cannot be partyi because it is a structure you can also create one. That's not associated with the document, in which case every member will throw a valid operation. So what they say don't do if.

D

You say default and.

C

Then ask any of these methods. What's going on, they'll grow up? Why are you doing bad things? That would be the only time that you, with the exception of the type property that will return, none, which is the only time you should ever seen them coming out of it- is that you created it as people do. Does this struct also track disposing the document, because they're started as a version of the document? If the doctor disposal of these will indirectly grow.

D

So Jason talking type is a superset of what this thing can be correct. Yes, so.

C

You would never see one that says, comment see previously, they break for God and you will never see in the Ray or object. So does it make sense.

D

To use booty use the same enum, it would be a copy of the enum. Those three right.

E

D

You know basically to use this time. I need to know is that to use JSON element, I need to know its type of this property yeah or you need to a circular.

D

If you know your C versus.

E

It's an object.

D

And so, if I, if I mean the case, I, don't know that would.

C

Occur again, so you can see spirt object, which means object, but you can't see in the object, because that's just a marker, we.

A

Would never give you.

G

An element that.

C

Represents the end of the object but giving you the element represents the object, logical concept, I'm.

F

C

Probably prefer just which were involved out to set external objects, but that implies becoming a genotype.

C

Don't make like right now it's it's using the same enum, because it it's really just a pass-through from the other guy, but I'm still might make another.

D

One, don't we need them, do we need it to be property under like why not make it such that it's either object right. What about.

C

The reason you need it is, if you are, if you are using the enumerator on an object and that's the only time you can see the property, so the enumerator on an object will give you the properties. So then you can get the name of the property and the value of the property. Let's say: look I need two pieces of information.

C

We talked through several different clothes of what the enumerator can do, including bouncing between the property name of the property value, going just down the what we call the property name axis, which matches what Jason met buzz and the very interesting model that I started with, which is go down. Only the value, access and often the value. We allow you to ask what the name once and then it throws that you didn't come from an object where.

D

We could end o matic that could direct error. That one was that you know a tuple of name and value right.

C

We would need to split the enumerator array and object array. It doesn't have mean just like someone, you numerator over the way you could end up. So you learned X, 1 and X 2. Then you enumerate over an object. You get property, 0 values, another property 1. Well, no, you get property, you get a node called property name or whose type is property name which is no K 0. And then, when you move next, you get 1 and off of each one. There is nothing bottom start at the bottom.

C

Third of the screen, get property name to get property value. As we see some properties, not both, but is it really.

B

Just the name, yes, and if you want the baby up to movie night right so again,.

C

On the next for being similar to long a public event, yeah, yes, are you have to party buddy so.

H

This is very same open, J.

C

Properties engagement that minute, which has the name and the name property and the value property where the value property gives you back a J value. This means that, if you're, if you have this inside of a for you, you need to keep state outside of the forage in case you're, using an in case your opinion rating over log. That's right because you need to you need to know that every odd thing that uranium rating it.

D

Was a given property names.

C

If you want the value, okay, okay, okay, that was the zigzag.

D

C

A comment actually comment so.

D

I have to tell you to me: it would be easier to understand the model you find you Jason element can be one of the three times yeah, it can be their value. Then I can call get ain't, get you know in 64, and these things it that's all I can do if it's an object. I can enumerate properties when property is a tuple. It gives me it's name.

D

Let me not have to use a total part, it gives me a name and it gives me JSON element or I can enumerate, and it gives me those elements. Basically, the type has three modes and the API is kind of what I would expect in the mouth here. It's kind of like enumerate. Children well I, need to know what it exactly does. You know like we.

F

Can make you like you I.

B

Don't know what that many people think I mean I get disgusted with yesterday with German right. If you really want it, so you can actually have the fake hierarchy. You can actually have over the demo data. We have a base, a construct that is the base type and you have other structs, are logically derive type, and then you may save it. It does the conversion to the base.

B

You have an explicit conversion to go through the motor after one and then you basically have literally like three types: they describe what you can actually happy and then the base one. All this gives you a kind that says which one of the following three I and then you have two cars. The.

E

B

Of that model, my opinions, because it's what a true hierarchy, you still have to know, which way to go right and then you basically always have to cost effectively to get to the actually yeah.

D

You based on the kind you cannot afford this one. It's.

E

G

D

The you know, kind, I, think the ideas should be like some subset of api's works. Sometimes all we do what research, but again the thing that I was describing either idea works or it doesn't not like it does different things depending on well.

B

I mean either have different APRs that have the exact same signature by different names and one closed. One doesn't just come.

C

Up with different names for the array numerator and the object, the numerator we can library elements and.

K

You know a properties so like in the XML we just called them: children and siblings and elements you.

C

Yeah, you can't ask about your siblings. This readers cannot from one element. You cannot go up or sideways. You can only go down, so the side was in place doing that from yeah. Well, it's amusingly. It's easier to know what you're in the conventional treatment, what your right child or what you're right sibling is. That's actually easy for it to know, left and up above partner right.

F

D

Then you know, and then, if we did, that this whole concept of JSON element being a property would go away, it can only be object, array or value to me. It's kind of easier to I.

D

C

This means that whatever the object enumerator is is giving you back essentially the property name yeah, and that we just called the BFF it.

F

Would be Jason properly incident Jason elemental able to have a subset yeah.

C

All of it have on it is.

H

So you object value and rate. Why can you remove property? Why can you want anymore property when.

D

You eat when you basically in the object mode. You will end omer eight. You would get these tuples. That's all so you don't like. They are not json elements. They are just result of the enumeration on an object.

H

D

H

Property property as a denominator public, exactly because to access that gesture element that is probably now you never build in. Oh yeah right. So if you use any of the indexes.

C

Where we have the utf-8 one and then to utf-16 ones, if you use the main indexers, you get the value about the property. So the only time this current model, when we get the property node, is in a new right children, but we can split it to the season. What do you return is the name of the development defined invalid.

C

There's also separated from it, because I took the order that they appeared in the generated ref dais their reps. Yes, there's a there's, try get property, you.

B

Know it's very unfortunate because it makes basically common query operations. Quite involved might be base. Have you you cannot have a compound thing like this one, this one this one and this one, and if you can't find anything, that's fine, which is the board. You.

C

Can't have these for a moment. You could have that much.

A

More a little bit tight that it matters, but also have them looking default, which would be but yeah.

B

But before they're gonna know is language to explore. If you return, nullable I can say the you know, question mark dot and then I can just say. The whole pipeline is invalid. If one of them cannot be found and then I can check with a fondant well I think we should think except much more useful.

D

Lots more commonplace, do I know the skimmer I, don't well.

B

You may know the schema doesn't mean that somebody gave you the correct project. It might be often as well yeah.

D

Cuz notable types are still not as okay. This is a reveal yourself if you really want perform its no.

A

D

Not a convenience, you know.

A

D

A

Be you know you.

A

A

I forgot what they say.

B

There's a civic thing, you can say give me that pipeline right out and then you can basically say if any of them is now a question mark question mark you can say: well, then you know otherwise, given the actual video, and that is I mean much much more convenient and no I think if this exists great excellent. If this exists great, when.

D

You eat the amount of I need not about the case where you don't know, I agree with you. I'm just I want to make sure that it's super convenient when you know that you have the values which is common sure, but, like again like do you want to blow up if the schemas invalid do you agree and when I know that the values are there and they are not there? Yes, I want to blow up reckon.

A

What do you mean value and things are initial optional? Well,.

D

So you know, like I, issued a query to adder and I told it to return this payload and if it's not there, if there is a bad summer, so I guess I wanted to blow up. But maybe it's okay.

H

I don't know, but given that this is a read-only representation option, prime properties or things that were potentially require you to modify either remove or add elements, but something that is not supported here anyway. So if you get rid of the octal properties, you would want you to see like an easier version, not something like this. So to support that scenario at UT, the interceptors to support a scenario doesn't necessarily make sense. Why.

B

Are you doing because I mean, like just people option does me know what it is here that it just means that I mean? Why would you use this type to begin with, rather than this? Innovation is I, think a fair question, but if I, but down Lee the type representation for that I just want to exit some configuration data that things can be optional like any other way, but.

H

What do you do it made the fact that you have the option or not awfully well.

B

Then there's to kill either either the document is just invalid and you don't want to blow up with you know invalid blah exceptional started. We just want to maybe just ignore the context file right, in which case you can either say well, should we can write a catch enough for the exception.

H

Or use the right word. So what use a bracket property to talk about me, but yet again.

B

They even go down the path where what is very concise in this syntax becomes like a ten minutes ago, because you have to do it not make thick. Compare like how how X things work right or you know the whole XPath kind of thing. You basically have one single string or you can say give me give me all these guys of this name where this thing is set. If they don't find any, that's fine, I don't have to deal with any no checks along the road. What, if you have been sort of an.

A

Index or what, if you had like a dart, get method or something that took the property name and what's wrong and all that there's no way. There's all finally I mean I, don't yeah. That could also be known as it.

B

Doesn't internationally.

A

B

Reads just about the size and it.

A

Would it would keep it would keep this pattern that you're.

C

Looking for, except for there would be three more letters for each instead.

A

Of ruining a question mark bracket, you would have the question.

D

Wife daughter, it is but I I think it's so I was not pushing for one over the other. What I was saying is we should Oh about which one is the more calm. Okay, do I know the schema or not and then basically make one we get and the other one with the indexer. You know, whichever is the market more comment.

F

Is going to be your special property.

L

So I think worth Jason the best way to think of it as the the way people would expect it to work is the way it works in JavaScript, where, if you have an object in JavaScript, and you try and get a property from it and it happens to be null or it happens, to not even be there like. That's not going to explode and that's the way I did it and Jason on it and also to do with the way people expects.

L

The way to think of Jason is think of an object like an object and a deserialized objects and c-sharp, like you, would in JavaScript where people want to treat it like a dictionary.

L

They want to be able to index into things. They don't want to have to call it don't get value, method and person. The name will be index. They want to be able to treat it like a dictionary or they want to be able to treat it like a list and.

B

Go ahead, but when you say in jason, good nabi, you have a difference between not defining like what Nick. What do you return if I give you a string that doesn't exist to give you you give me back null or some some value that says: I wasn't here, I give people back null. Okay,.

D

Okay, so the next time I.

D

L

Blow up what what I do with then and like that, that would be the same behavior on JavaScript. What I have an Jason on? It is I here of explicit, cast operations, so someone could index into a object name I want to retrieve the title from it. F title happens not exist, it will return null and then, when their explicit cast operation is casting it to string, it will just return a null string. Well, a null value.

L

Likewise of someone doesn't explicit as to a nullable integer or a knowable date. I'm. Sorry I will just.

L

Like I think operating.

J

Like JavaScript behaves.

L

As the pet of success for the Sun.

B

So didn't quite catch the different behaviors like when there is a property, but it has the value now so.

D

B

Have the chain.

D

That you wrote on the board, but you don't use question mark- is just dogs right? Okay, just the brackets basically have three brackets. Okay.

G

D

The brackets you have property, a D and C okay. If a is null, it will blow up, I mean if it doesn't exist, it will blow up right. D doesn't exist, source C, it will not blow up. Is it it's right? It.

B

Depends what you mean, but it's basically returning now right. So if you, if you don't dereference, the mother doesn't go up but.

D

B

Don't dereference yeah.

D

I know how it happens, and it's just it's: it's a bit strange there, but.

G

I, don't think that says.

A

D

Sometimes the indexer will blow up, and sometimes it won't.

A

The Linux I never move now will blows up.

B

A

M

B

So it's the it's the different.

D

Syntax, it appears as depending on you know, which one is missing: it blows up.

F

Well, yeah! You also have to consider that the sometimes that people write in JavaScript is if food.

C

Apps and Google X, not Y, & ambu, dot, X dot where Z whatever, whereas the syntax that people write in C sharp, is question mark talk, question I, don't have to not don't write by and large, so I.

F

Mean it's well.

C

It's you could you could potentially make an argument that you know yes, it's it's Jason and Jason has its origins in JavaScript. Obviously, but if we're trying to make this easy for C short developers when it might make sense to new citizens out.

B

Of you that I think like to me, it's like I think that we should embrace the language to make it to make it readable, but I think when it comes to the semantics of the thing, I think it's okay to stick with JavaScript semantics and say this is how it behaves and then just use c-sharp mechanisms to do a number. Well.

D

Don't you find it strange that all indexers.

D

Except this one, so.

B

I would agree with you on that one, but I think the difference is that you don't really have dictionaries of dictionaries for the most part right. So you never have to swallow me. You index index again index again index again right.

B

So, for example, in XML, one of the reasons people like X have so much is because you just write this one long thing with slashes and you don't care which one wasn't found, because you just get an entry so that it's empty right and that basically allows you to say I, don't know a / b c d, and then you just ask: does this produce a video or not yeah I, don't have to do like for nested check.

B

G

Like well, that's.

B

The reason I, the only reason by Jacob, in my opinion, is use it as useful is because you don't have to do this like yeah, like repeated, not checks versus even indexer was written like this. You get the same benefit without any of the complexity of this API. It's what.

D

You are you arguing for your novel thingy because that's different yet from you know the behavior of you know. If the first one is missing, the second we'll throw you basically saying you can change them and they will never throw ya. They just returned. Now, that's what I would say and then, if you I mean there is not but I'm saying this is not the JavaScript behavior, which is if the first one is missing. The next one will throw.

N

I'm not sure I understand because the JavaScript you don't.

B

Dominica and now is gonna be same excellent. Why don't ya.

D

F

Missing this, you will throw.

C

G

C

Is sad because of semester.

N

So even understand what this my house is different, or this is again the same behavior. No, it's different from trips.

H

From an expert or a package, so you're pushing a requirement expose a path or to that where the behavior of exponent a path doesn't match either of the other top or bottom well.

B

Because then it depends what you mean by that right, like they did way, you would so it logically what you write here and smells good as any dot B which will fail if.

D

He is missing, so this one doesn't exist, you better get an exception right. No one is missing, you don't get an exception.

C

Maybe write a question mark me. Question mark C question mark D. Then then you would get back here consistent knowable, but if you just got it like you wouldn't gamma script, then you would get it. You would get an exception if something in the middle, which is.

F

B

The thing is: when you have a value of the left hand, side or anything, you have a video on the right hand, side right, so this is usually name right if this whole, if this cannot be bound, you get now right now. If this one already was now, then you get an exception, because if it had you referencing yeah, yes, but.

D

That's how any foreign language does ever work yeah as an example of the jQuery, and we are saying this is not exactly how jQuery was no.

B

Because, basically, they would just propagate them now. I know how it works is evidence.

D

Now nobody's getting the same model that you have here.

B

Let's just say.

E

B

Resulting value is inaudible type and, yes, you have to check for now, which is effectively the the only way to make it.

D

Right is it like I know this email and therefore I'm so surprised when it's not there I'm, not the schema. I know that the payload then I'm super surprised that we throw when we do what you said, which is they are not at moved, and then you have to write this somehow wacky syntax, at which point maybe I, won't even be ferry. They J query syntax. So.

H

It should never, why don't we construct a gesture element? That is the type of none, because the type now means it was there and said the word no.

L

She would say: I would have a type undefined.

L

Saying or at he prayer a different way.

D

I

Basically, dot.

D

Syntax, like you, can pass a string and you can pass more than then just a string. You can pass string with the dog in.

B

The middle: well, my the only argument against it or my opinion is because I don't I would not come up with something. You know you basically have to do whatever the J path, so it takes respect it. Is there.

O

Is no spec well, there is a somewhat conventional agreed-upon theme right, yeah, there's a blog post that seems pretty pretty pretty spectral holidays.

D

So you can pass a string that has a dot we split under the velocity. We wouldn't do it as inefficiently, but not if you split on the dot and then we index into the first one check if it's null or not, and then we option index it with a second until you're properly.

C

Then hazard odd.

D

And then all hell breaks loose.

C

D

The property names cannot go, oh yes, they can. You.

C

Can have anyone.

L

C

C

D

And dog also means something different, because.

G

D

It because you so.

G

In which case we switch to the index search.

C

Yeah, you know so you switch from using a dot open square bracket, like quote whatever you want now we're playing dots and other like it can can start with numbers now, yeah.

D

Anyway, so what it means when you visit, because every call out JSON object, is a dictionary yeah.

M

D

Or just also, when you add the perfect, you compute the same syntax to basically add a property that has a.

L

Mixer should behave like traditional JavaScript indexes. That's like a Dacian motion, magically support, Jake Python them better appear separate. That should be a separate method.

L

From from these mixers, no because that would have an ugly syntax.

J

J

L

Think they should be adjacent element which represents missing or not found or undefined I can to find what how you said and.

G

And then, if you.

L

Try and index, and so something which is a bit undefined flag is true. Then you would throw an error or if you try to say, get in 32 on it, then it would throw an error, but at the same time there should be get nullable and 32 or something like that and if you tried to say, get nullable and 32, then it would just return the nullable value. Likewise, if you said get Strang and it was an undefined type in order to know.

F

C

Yes, why nobody does not.

F

C

D

C

Right now it has one default, has a Jason token type value, none, which is the state that the parser uses to explain. It hasn't started yet and we're gonna.

D

Turn back default.

C

In Jason element, at which point.

D

You get I, don't have a type I, don't know your eyes now. I find it very lucky because it doesn't support this chain, syntax in C, shot so I. Think again, I would say we decide whether which one is the most common scenario and either do what email sense or the words that it now says, and that alternative to take you guys to get you the knowledge of values. So.

C

You think that we.

D

Want the indexer and a method called get.

C

Property and one of them is knowable and the other ones are that we decide which one we think it should be clear. I think James has suggested that he thinks that the that the indexer would be the knowable one to match javascript patterns I, don't.

L

Think we should have Malibu I, think Jason element should have a representation of undefined, and if the key is not found, then you share met undefined.

C

D

So if we do that, you cannot use syntax to propagate the know, I don't understand we let.

F

D

Element that can be a null because then you cannot use. You me Antares aliens properly.

C

Method or something which returning like an a the return type of some extension, but there was something with Miller will be knowable of his element. You.

D

Can always build an extension, no, oh, but why would we have something in that time, but then I have to well.

B

I mean you could say that if you index into now, you get just get back now right, in which case it's it's it's built into the radio itself that you.

B

D

B

They will do that. I think that I'm just saying if you want a proper, if you I, think if you want to use the special available I think you have to build publication inside of it because of the voice ending and on top is ugly as hell or.

G

B

Just return another bowl of blood, and you just do it with the language syntax, which I would prefer because I wouldn't know so, do you I mean if you don't have it I just wrote the code for try, get value chaining and it's not entirely horrible. You know like it's pretty like with without var. Syntax is actually somewhat decent. It's not actually sure sorry.

D

Good value can be chained well,.

B

You would write it like this man, I mean. Actually you.

F

Would you try get value.

E

D

Not entirely horrible and that's like horrible is well.

B

Depends on I mean I think this is concise enough. That I pressing ended with that I mean I. Would I would not prefer this over this I'm not insane again.

C

You could write an extension called you know yet, which.

C

D

Think we aren't thinking you yeah.

C

F

D

Which one is good, which one is the indexer one return exactly I.

B

Think shipping, an API will be basically assumed people might help us on top, is not a good API like basically saying that no, it's like oh yeah, you can't make it usable.

C

One tapes: we don't string the only Spanish orange drink and we move out of the end episode into a different method. The reason for this is I have a proposal now. I have a proposal for a YouTube platform, literal utf-8 string and if that comes in, is going to get the wrong index one. It makes this class unusable for certain people. If this was everybody wants to just write, open square bracket, a literal close that close, yes and they're closed, but.

J

C

Can make that work efficiently so such that it fits the correct over maybe.

D

You can get.

C

Utf-8 string in in 303, you know.

D

It doesn't any way to demonstrate justice.

D

Yes, it requires one extra well.

B

It depends on yeah well I. Definitely if the lay, if the the I think I want to say. Well, you just pointed out is one of the reasons why I don't like target typing, because the basic guarantees that any existing API the accept string today, we can never ever add a utf-8 overload and have it work, which means honestly, like they need to have some tags on the call side. That says no! No, this string is a utf-8 string.

D

B

Sure, but that is very error-prone.

D

Also, you can cast you.

G

Can interesting API.

D

You can just pass literal string cast to neutrinoless pound of body or to whatever is.

F

H

D

Yeah, no, no nuts on the target type of database, oh yeah, exactly FIM.

C

Because in the end, you see a big string feature grants like I already have support for utf-8 for minerals, and there is a that we keep hunting on discussing, but it would actually make this work. Suppose.

A

Like but how does this little sentence records? It's just normal quotes right. They look like a regular three minute.

J

It's not normal quotes. It's usually a page turned on literal of normal clothes claim. Okay,.

C

J

C

What I'm also trying to push through is if Rosalynn sees a literal string and the target may be say, utf-8 rain hasn't ran ever just look at component, where you know what I meant it just make it work, but.

B

It sort of attorney I think my CD is saying that you have a normal string, syntax and because the target is effectively constrained to utf-8 strange, don't require the language of the calls that just make it work right. I think, if that's the only mechanism you would have, that would mean that if you add an existing overloaded takes utf-8 string, it will never become because it arose the stream corrupt and that's why yeah, but.

A

B

But basically the the workaround for the call set. Is you cast yourself, which is the same thing as target typing? You just say: string the tool menu prefix it with whatever you teammates that.

F

Works today, but.

B

But I think the problem of that is that's. Why I think it's better to have dedicated syntax on the court said: is that it's error-prone or.

C

C

Reason the reason I'm bringing this up right now is because these methods have different performance characteristics, oh yeah, and if you're passing in a literal string, if you're passing in a literal anything you want the highest possible. Well,.

B

So I would say about all I'm saying is that this API is not special. You have this problem everywhere else in everybody, except the string today and I think in order to really do what you're suggesting so we need again a predictable performance. I think we need to handle the language. The.

C

Interesting thing, which is off screen right now, you look at this type. Unlike the other day. Some types that we did discuss does not contain right now we're in utf-8, because there's the only thing in this entire time that needs to know what the underlying encoding is is the escape valve, for, if you get a big integer, please just give me what the what the underlying encoded data was, and so right now try to draw value that out slight and the reason it is tries if we never had support for Jason over charge.

C

That will not return.

D

Plus I don't know: what's the actual encoding in the payload I, don't know how to use this type efficiently, because I don't know which overload of the indexer should I write. So.

C

My my goal with this is, unless we want to put utf-8 in the type name and say that this is not, will never ever support anything else and it can support something else. It can invite in my goal with this is let people that, if they write code today, if they write, say an extension method that returns a big in turn, then it won't work in a future release. I, don't.

D

Care if it's performance than it do to realize, I want to work in so.

C

Maybe it's acceptable.

D

But I just want to go. There observe that it's not completely nothing! You, the leaky, part this. You need to know it to know which indexer stuff, but but otherwise.

C

We can, aside from the performance characteristics, is go change, but nothing in the surface exposes what the underlying recovery was. Once once you have calm parse. It pretends to not there until right there, where it leaks it out. It's a database, and so the question is what we do: try to get raw value. That outs, we don't remember a byte or do we just make it get raw value, get rid of try copy which the purpose of try copy is.

C

If we added support for utf-16 at 32 later in the transcode, do whatever the destination can.

K

We could we not just say I don't get raw value and if users know the encoding is not utf-8, then they use system text encoding to the conversion themselves. No, because if it's backed by utf-16, we don't have bytes to give you well, I mean you could still return the value and fights and then make him still call, because it's the same thing text encoding has today the.

C

Problem well because I have, if I'm, giving back read-only memory a bite if it's backed by utf-16, the only bytes I can give you are that I call encoding turn this into utf-8, allocate a new array well.

K

No, you can get a draw bite for a foreign array of character, using text encoding, yeah.

C

But that's a new application at that point. I can't return you the memory. That is the projection over the memory that you gave me yeah, which is what try get wrong value says it is new zero work other than give me the slice um so you're talking about a theoretical future, where your constructor accessory don't list out of chakra where the parts Benton has no factory or me don't worry about this. So where do we need to shape those should I get their own party?

C

Other things try to get raw value is useful if you think you might have a big integer or if you want to preserve a a double using. Whichever of the many double notations.

E

Do we want to shape it? We just not shape it and then, if we have this problem, we have these methods right there, but they do complicate that the other thing it lets you do.

C

Because try to get raw value on on start object and start array give you back everything from the open curly for the closed curly.

C

So it gives you a very fast flip this element into the existing tree, the plane, that's making this a little strange is because we're using bite everywhere in the utf-8 reader, and here, like we're, saying please give us binary data straight off the wire, and this is a binary payload car, sir, even though the format happens to be types, if you take charge as an input type now, you're saying oh by the way this is now operating upon text not find every data, no, the wire, you can wire, you have 68.

G

C

And Venus ordering yeah why we're always stars the CPU is concerned, it's a skinny white, where the Machine, your Pocky, what happens to have the same NDMS in the architecture? Is you any.

D

Generator I think so we have a JSON reader, it's it should support all the power and all the things that you can do, I wonder.

G

Whether this type should not.

D

Be here utf-8, they say yes, and this type maybe should be simplified, and it's like you know. You have some issues with big integers and what not well you there either. Otherwise, we gonna get good daddy, yeah I. Think that I think.

C

It makes sense to have the exposed, because, if you want to do the convenient path to get your sub-element like, if you want to resort to the using the reader at some point, like you load the document using skip comments, you. Finally, whatever sub element you want, and now you have the range, and now you can invoke the rear on that sub range like because we're giving you back the coordinate. So the element at the copy that otherwise you have to like. You now have to go into a whole thing back.

H

At the reader, including tracking, yeah, interactive, precious.

C

H

Because somebody's check-ins ability, essentially yeah, if you have a distant.

G

Object document.

H

And you want us out talking coffee format. Rather, you searching yourself, you can use the Dom search, and now you have the Rob slice on your input that contains the sub document. Why do you need the.

D

Ross lines and you have JSON element and now I can participate on element two right there and it just blasts focus on meditation like what saturate.

H

D

Of the thing, what.

H

Customization, we imagine like custom typing like big integer or format differently. Instead of default format, you easy different format. I, don't you super strongly.

D

About it, but I will simplify and get it right, and then you can always add later back. Doors to write to device is like. Are we really going to a duty of substitute support us in the future to.

C

This type I mean if you work. So if you look at that that users there are the 99% of that that user to you string yeah industry in his life, and they will look at this and say why doesn't this take a string? Yes and then they would want something that works on string. Is that they've done string things and we can give.

G

C

That works on string and then it will just transcribe them being wrap around us. Well, the question is should like. Is this a useful and you know essentially is is Jason documenting Jason element? Should they be a useful exchange type regardless of the underlying encoder I? The scenario that I've been hearing everyone we've been talking about. These types is I'm I'm, getting stuff from the wire whatever's from disk.

C

For me that works something else, and if that's a scenario that we want to focus on, like that's, that's utf-8 and that's the scenario these types women file, this file that write all the text for utf-8 or you can flight and fall beauty of anything you can. You can give it an encoding, but it's doesn't so.

B

But I, like it I'd, say: let's say we extend this to utf-16 right. So how would this type work? Would you expect to literally have an if everywhere, where you access data, or would you expect that you transcode one to the beginning, and then you just have the in number representation monitor you.

D

Policies on the bike, you never gives you access to the actual thing, except for this method that I'm arguing you should remove. No.

B

Intercept, that's our masking, so basically that means every single time you ask personally, they haven't passed before you basically have say if utf-16 possibility of 16, if you take eight parts of you David so is that the type of you.

C

So if we took a utf-16, that means that we have a utf-16 version of Jason reader and in the factory method we use that to build the database. All that the database knows is where a name started to stop. It actually doesn't know what the name is when you go. When you ask for a property match, it then has the magic so right now, if you call the utf-16 versions of the index seriously, they have to transcode they opportunistically transcode, to find a match. Well,.

D

I think what you know it's asking at the end, so a little bit finding the the you know the payload yes, but once you find the parallel, when I call get value in 32 right, you will have to have an if deck and basically say if my table was utf-16, then called a sparse other way expose this other parts. Yes well, that would be all buried inside of that. But what wouldn't?

D

We have two different lunch without it, because you then cannot pass somebody so I do agree that there's some value I, don't know whether it's worth it, but there's some value in basically saying well, I'm, just passing you JSON element, you don't have to care where what was the source of my data? Yes, you can idea, you know genetic.

F

Algorithms and your generic and and I I'm sympathetic.

C

To that, but this has come up with utf-8 freedom string past where we were debating should we have an any string type around it and the answer was always no. You have to know exactly.

D

And I think the reason is that for string like the performances you know, single British is very important and here yes, there would be some performance now, but maybe it's ordered that in.

C

Particular if you, if you're, asking right now for what's the name of the property absent us having an allocatable utf-16 there, utf-8 string type because we need to handle it seeping prostitution, the only things you can do are asking: what is the raw value of the name? If you want the unencoded everyone, but not transfer or please transcoding estate, this is so right now. The only way you can get back to main with a property that has had the escaping from removed from it is against extinction.

C

So, if you don't, if you're Christoph, then you don't want that the.

B

Reason I'm asking is because it's just a measurement saying like you know, basically JSON document has a parts of, although that takes string rather than utf-8 bytes right, yeah, yeah.

G

B

Then you can just say: well, that's, unfortunately, I just transcode this tf8 and then I do the rest of parts, because I mean at the end of the day you can just say my normalized representation member is always going to be utf-8. And if you, if you really wanna, have a UTA, so utf-16 version of triquetra value, you just have a mainly convention on the method and then, if the encoding matches, you just return that if it doesn't you're trans code and like that means you can pass the same thing everywhere.

B

But you don't have to like heaven. If check. You know everywhere.

F

B

But you only pay the penalty for people that deal with utf-16, which were arguably no people.

C

Yeah, this is an abstraction that your mental house, one component, a two component, B or two components, don't even know what the underlying encoding is component. You could be calling try, given all value as an optimization, not realizing that it's actually allocating Emerson all right.

B

In which case you could also in you know, expose the underlying boy you could, you could basically say like what's my backing store, but if you care.

A

B

Could always say the utf-16 version is always going to Trent transport, because JSON document internally is always cool, storing to memory as utf-8 right.

C

Now I mean somebody else can just write that on top of this right, which and that works right now, if you use this type and you have 1 billion 40, 8570, 6/12 tokens or less in your document, it allocates 48 words that is it the moment that we automatically transcode charville you it allocates that number of bytes plus 28, and so that that would wildly change the characteristic of calling parts so I, don't think that it belongs there.

C

If we have a UTM paper year that understands tolerance, then it can do the same I, let this carnage start and and I move on, and that's what.

B

C

B

Here so but then then I would agree with Eve and then it sounds like the time is effectively utf-8 document UT array element except.

H

Everything on the stripe is not you David, except that right off I mean a psychiatrist of the indexers. That's what I want to remove it, and then we can decide later, which.

D

Way you want to do the moment. We remove that, should I get wrong yeah. We don't have this problem. The whole discussion we still have n. We can.

H

Always add these metals later, if we decide that we.

D

Are the difference is.

H

If, let's say someone passes in the distal element to the writer, yes right, oh yeah, that could be internal.

C

Which property in vector is correct.

D

But that one at least no matter what is not that? Ok, it's just working, but it's never done, but it.

B

Seems very to me to ship at times it doesn't have utf-8 in the name and the only implementation they become. We have a duty, a way that makes it.

J

Doesn't owe the Chasen writer has utf-8 America yeah.

B

Like everything else is utf-8 in the name and like this type in part literally called utf-8, Jason reader, and so like only.

C

In that only in the parse method that takes a thing called utf-8 X right.

B

But all I'm saying is it? Does it assume of custom I think you have to make all mine up would be ever one of a generic or not because if the answer is no, then they better call these guys youichi I made something. The answer is yes, that I'm not called as utf-8 in the name. I, don't think you can be, can propose that like postponed a decision because- and that's my yeah- you have you shipped the wrong type name at that point. Right.

C

If we, if we think that we would never ever ever, take this and they can do I know that is only doing train, while still only doing transcoding in the property effectors grant, then then we should just slap utf-8 on all of the names and that's all the other type things in this document.

C

You can't Big Basin at work, so.

H

I guess the point was that the notion that there would be encoding specific so then we have multiple types at the bottom, but talk about types like document. Unless you have easy desert, I'm, not encoding, specific I support both or they can spoof in the future yeah. We should have them in there and you get a choice. You dr. banner, a petition. You just read this document say we see daddy's land or whatever else, and that's that's what I was.

C

Aiming for if we think that we would, until we come up with the time that we want to do it, that we aren't gonna, do it then like we could then take this copy it and remove the word utf-8 from it and figure out how we wanted to handle be telling you which encoding it was based on.

H

But that forced us to add to me and give it to this data document, which.

D

Also, this is also here's.

H

D

Let's see interview so, let's say initially wish it and it only. You can only pass you give. It asked you here paid to a department and in the future we discover that we want to enable it for utf-16. Okay. What would we do if this type is for muted.

G

D

Would we want to do let's say we are designing both of these scenarios today yeah, so we have a choice: it's not like it's already cuz. We were doing both of them today. I would put.

C

On either arm Jason element, something that tells you what its native encoding is and I would have triangle robin tunney count. You know whenever you bite and try to get raw value without meet up with memory of chart and.

D

Okay and what new methods didn't exist, so imagine those two methods- don't exist to d'être values and now we are designing. We need to be able to parse both utf-16.

D

C

The only differences there be another there would be another parse overload and possibly a property on here which will tell you which of the two indexers will be marginally faster. You you do so.

D

If we that's what we will do, then slapping utf-8 in front of this type thing want to prevent us from doing them right. Yes, yeah.

C

So like it's the, if we think that in the future we would do it, but we're not sure that we would do it and we want to make sure we save the name for when we do it right. We slap utf-8 on this now and then, when we do it as a hybrid type in the future, we copy and paste all the source code, immunity and.

H

Now you have two types: one is.

C

Discipline board and one that's a push. Yes yeah, it's instant obsolescence and the one that supports utf-8 will be faster on utf-8 data, so.

H

D

C

D

A new one has to support both compounds inside every single method.

C

D

One is somebody pass me this thing and I don't know yet, but in a lot of cases it would be I got the payload type parts that I'm using this type I don't need two colonnades yeah, especially that they are just on they just control performance director is coming up. In fact, it.

C

Doesn't even have to do with or.

E

C

Like bill the like dynamically table inside and that's it for the process wrong well,.

G

It's a one. It's a.

C

Lot of them like, if the problem on the hybrid one is that it is too complicated with the everything that, if what's the backing a coda you can, you can make an internal type hierarchy, yeah and just realize all about.

B

This yeah I think the question is negative: if I'm using utf-16, why would I use this vibe and nothing? The answer is: don't leave because I want to get rid of Jason. Oh man, wait am I.

C

Guess right, but the same thing here of nothing in this prohibits us from adding utf-32 3, like literally just this one method is the only us in the abstract which one did I get wrong. They get wrong value that you say we should get rid.

D

Of well the Hornets carry.

E

On so I copied your methods.

D

I still argue that we should remove them, but if we don't quite right that value returns, freedom in Memorial, not spam,.

C

Triquetral value because I have a memory, and why would you limit you on what you can get back I.

D

Talked about close the time it's not this year!

D

This is not really preventing you from doing anything, because you either queue fundamentally have to stall this thing as memory yeah, no.

B

D

Let's say, let's say: I own the data and now I passed up to somebody. It would be nice if they couldn't do something really bad with it. So you want to stop them.

D

C

Not sure you think.

D

C

We can out of this fan and based off last week's discussion. They can figure out if they have the original memory, they can take the memory that span that overlaps. This fan to ask the index didn't return or slice back to memory if they want.

F

D

We can defend all this complexity and the decisions about the lifetime. We just.

C

Then the only real scenario.

C

I'm, the only person in the world who cares about the imager and I, don't like Jason, so there's probably zero. So.

J

What was one of your scenarios? I.

C

Have a system is creamy and I want to call parts patent. Assistants first was that the sticking point yeah, because.

E

C

If we have per statistically system utf-8 straight and then we just said, convert a to B and then call this parse method would that work for.

A

People I think so I mean it's. What I'm saying I mean I.

C

See them today and say what work like I would want to make the caller do it.

C

Yes, if somebody assistance during they just call this thing with encoding, that you can make that get by yeah, I think or talk to utf-8 rings. A method exists so.

B

The only question I have is like: why would we not do it ourselves, because, fundamentally, if we had a process that it takes, this training, does the transcoding the one difference between that and doing a populist performance? So then, even not people user and complain about perfectly optimize. It.

H

B

Not a fundamentally shaped problem is better.

H

To for the user, who has a data payload to comScore, to give it first then give it to us? Maybe we are slicing and dicing and doing also demands to do it right.

N

Are you saying which we still support in the common case yeah, because.

B

I mean the most common case. Have you Jason lettuce today, I have this I have the Jason a memory in the string I just wanna I, just Jason Garnett and cause to.

C

Be to be clear, the reason an adoptive Jason.

B

C

Sprinting memories, because you probably read it from the asp.net request party that.

J

C

Using full framework, for instance, where terms it as a system string right right but asp.net is considering like we're going to give you the data as utf-8 is UT up. Second conversation.

B

That's taking place today would have been. This is a problem of things that I mean you might still get the string from it. With another place, I mean like, like the only difference between : ism yeah. Other one is performance buttons. You can stop them as your own code, but I'm suing the transcoding, quoting the UK 81, or just don't care, because you all you want to do is just be done.

C

With it right, but.

B

C

What I was arguing is, as the rest of the staff comes online, talk to bottom, like what you will be working with is bikes or utf-8 under the covers anyway, like you should using the new API and the new staffs talked about. You should never do. Is criminal person so.

B

I would agree with that, but I think that, and this goes back to the like, do we want to make it? How many like do we believe in providing more hoops for people to jump through just to make them aware if the if the gold is API is to say, look if it built in version, 2 did deals with Jason.

D

I'm, assuming so, we have been for last three years with there's lots of api's data for super advanced scenarios.

G

D

And we kind of almost didn't think about issues like this. One I feel like maybe around this type is between. You know it's an idea for Ben Adams, it's an API for an average of the developers and for those you should just make stuff work. Yes, they notice a problem. They can transform themselves, they can get, they can not get the string and go back to I.

C

Finally, agree with that: what I don't want to end up with is one over. Will the parse that's all of one and another over 600 done, but also okay? Well, we welcome once.

H

C

Hiding it so technically, once we're hiding it in parts we can make a documented like we can grow it for 48 bytes, that a to that, oh and we can hold a second.

C

So we can, we can hide your string of less than one megabyte.

D

Any deputies we don't like it, we can optimize it event, our code by basically cutting a utf-16 reader, but.

D

H

You add giant feature, but we just you just said the only value.

D

Is people who, like both big integer,.

C

D

C

The writer is not configured to do pretty better, then one option we have is to say that depends on if we call the non-printing option, minimum white space or what.

H

Can be internal for that yeah.

C

It does happy public when it's a question of. Are we proposing ourselves too.

H

B

Again, in this case, you in you can't really also have these method. Transcode yeah I mean I, give it keeps the primary goal is to make them work. Well that.

C

Will give you an exercise of try popping, would always work to try to get.

B

All I, see okay by the I, mean that.

J

H

If kind of draw Denver can you do crack copy another.

C

H

Can get rid of the bra value they get for now and we can come back.

C

With the scenario we're going to have the scenario you.

B

Would only have the copy one, no.

C

B

It you don't get, it make sense right if.

C

You have big integer, sorry, I'll call us all of the day tell them to try. It gets for your numeric type, return, false and sorry it's a number and it's.

D

Not any of a number types, and so in the future, not that I propose now, but in the future, there's so many ways to get people back doors like I can imagine, give me time and tricks on me they're right.

D

Instead of basically, you know letting them access the raw data from here from JSON element, you can say, give me there either that basic needs position and now either has back door and do whatever you want. Well, the UT effect is really like.

C

That well at that point, you're now really wanting to talk about. Well, that would be a trans code and do the thing and then later we could add the.

K

Why would think why would a big industry fail for double since double does not have any precision limitation double? Has a precision limitation, no.

G

I need things to large by.

K

Eights back goes to infinity and.

C

Then the Jason reader, we said we would never let infinity okay and I think that this should maintain the semantics of the double D's and I.

D

Missed something: what does the cons mental thing with the parameter? Read-Only memory of bytes called.

E

Vap Jason, so why read-only memory of.

C

Bytes not recon, see. If you want read-only sequence, then they can only hold half as much data, because the sequence position is itself bigger than my rope. If.

D

I need to remember how to get this data one so I'm, not sure why I'm going to use this type into your life. You know.

I

F

D

We're either in email, InDesign I'd now forgot what the end it, but reader is reentrant. So if I I don't know, if we take read-only sequence, is a fight or not yeah. Even if we didn't I can always write my it's complicated, but I can write it myself. This one is a one-time part yep. If my data is in read-only sequence, not the you need only memory, then basically I cannot use it. I mean I.

C

Cycle again, we can make a parse overload, but what it does is if I was near a pool copies everything out of the sequence along if you're less than less than we begin again puts it back like we can, we can read any buffers. We want.

D

And hide them in this, this well I'm concerned with that. So Castro read the new sequences.

D

To the size of sometimes on payloads, and it would basically always force ago and.

N

My argument right now is that if you need it, the whole point is you don't hide that copy from the user.

C

The fact the fact that I would have to drink the whole thing I, don't.

D

Understand why this way this type connect is their underlying reader can deal with read-only sequences. Why you're kind of right.

C

Now I have 31 in bits for what the upset of we only our sequence.

G

C

Is itself an object and for bias, so we have only 32 bits, because so the this uses a very, very minimal structure, so it can say on the array pool for as long as possible. It also requires to be global, because it's in federal organization, as it borrows bytes it doesn't borrow, and then it does strong projections on top of the bytes sequence position has an object: it's not a little bit so now this came. This could use its own a rifle, but it wouldn't be able to share with the bite of a tree.

C

So we already pulled is unique to this time.

H

What you can do it just changes when you have.

C

H

Was you don't want to hide the copy from the user? I he's saying force the user to copy rather than asking ourselves, but I will never use this factory right and you would use the reader. Then this.

A

Was meant for the.

H

Convenient scenario where you have one short memory: otherwise you never use Seco. That is.

H

Anyone who's dealing with batteries or all.

D

A single segment in the sequence I think we should just take by the range set up. Read only memory I, don't know you know like I find it.

H

Concerning the concern is around the limit of how much the near distance tour, the only sequence supports any size. Long well,.

D

And the very high level is there, you know: Levi was talking about. We are kind of building end to end story around here. Yeah the story starts with custard eating. You read on the sequence, so then what would we recommend now that people do and fork a pattern?

D

You know it arrives in 4k, but there is gonna, be you know, summary response, information and headers, and this and then you get to the payload like how often I am gonna be in one memory type 4k 4k is not a lot, and probably you know couple bit or many part would be already. So what were you proposed? That would.

B

You propose that we redesigned the time to say we have 4k, we just store more data to accommodate these scenarios, or would you have a different time or there's.

D

A like a change and advance for their interview. What the performance kit is. So, if the performance team is, you know, 10 X 10, yes,.

C

D

C

Every extra int, because I did a test once of growing into 12 bytes to 16 bytes and that costs five percent prefer I would think practisin. So.

F

C

It from 16 or growing it from 12 to 20 would then probably be about a 15%, so in trying to figure out also if the average user would actually have a redundant sequence, because my understanding, the capital Python and please correct me if I'm wrong, but my understanding is that within the cash flow pipeline itself, everything is available sequence, but at the time it's actually given to the application developer. Thank you soon, but it's actually in a single, continuous problem. No, no well.

D

Independent, so in ASP today, yeah you don't even have access to memory right. It's all stream, but if you program is really very noticeable but.

H

Returns really sequence.

D

When a speed of the team is working or thinking how to expose the buffers directly in asp.net, meaning the context context so and I would be shocked if they basically said well, we already worked on exposing directly the buffers, but now when I expose it as a read-only memory. So in case it's more than one question.

H

More questions can be supported later. Can these for your receivers right the layer active on this type? If you want to do so, there are two things.

C

We can do one is we can make this type inherently understand the only sequence which grows the table, changes which every bullet borrows from you, etc. So yeah there'll be a the amount of total memory of the process will go up because it's sharing less with other things, and the amount of throughput that you did in large document scenarios goes down because the structure is bigger, or we have just like we're saying. If we do persistent upstream, we have a parse thing that makes your daily sequence.

C

It rinse from the array pool it copies all of the bites out of it for you, and then you dispose the document that puts it back where so it would be better for the caller to do this in case they ever wanted the same contiguous thing just.

D

E

So there's also a hybrid.

D

So I don't know we so yes, positions.

D

Imagine ten.

D

Segments into an array and don't use position. Basically, you use two ins, one is an index to the array of segments and then the second is indexing to the segment.

D

I. Don't know enough about sequence: ok committed use, so he that baby.

D

Don't use weakened very three dummies sequence from a linked list. mmm Now it's just to eat index into the array and then the other index.

D

B

Of copying the whole content of the buffers you just copy effectively right, you just allocate the chain exam, which in tractors is probably to be like what 10 15 maximum like. If you really have.

D

Instead of copy, basically, instead of saying okay, the color needs to call to massive array and suddenly I create one gigabyte array. Well, we just create a small array that has many for one think about you. Have you know hundreds or I don't know yeah.

F

Stories are music, whatevs.

D

Oriented it yeah, there's.

A

Just a linked list, some puffins yeah.

H

Then line reader supports it, so they I see no reason why big circle supported here as well, so it would be a 5%.

C

But I think, like honestly.

B

C

This value spend, but.

D

That's already.

C

That's already, as.

D

Yet, like the majority of the cost in this type would be like I'm searching the database right. The moment I get the value so getting about. It is actually more expensive. It's so.

B

C

D

And value will be one addition, an index into an array so that extending.

C

Parts of the section is like what does mean it has to use the complicated code. Then I need to go from the end of this buffer and then you can start at this pattern. So the win it stands so.

B

Our expensive visit to have like an abstract type that does that it is internal like how expensive are me, taylor, berkhalter, for these individual things. They just have one implementation that deals with everything is super compact or another implementation. That's that's a utf-16. You have another implementation that is like whatever the signal change like how expensive are we table calls when, hopefully, the jet can see that it's just the monomorphic all set for one specific variable. Do we think mean? Do we think that it is too much I, don't know.

J

Yeah we're talking about using this so.

B

Well, the abstraction would be basically whatever you primitives are other you need inside the leader to basically abstract the way. The difference is between what Jeremy currently has and what we'd only seek with your limitation might look like. Maybe.

H

The only difference would be that you passed the only secrets to the reader rather than the good leader to deal the board directly well,.

D

You do use position right because there is no reason for it, because it reduce anything else, because you cannot, you don't ever need to store more than one of them when he needs to store more than one of them, so he wants to use basically a flat bar.

D

So basically you would have to do this feature, which is, if you take it only sequence. You convert it to an array right and now you forget about position. You refer to these things as through long you use long very, very few. Just you know divvy up the log into twins and need that's twice right and that's it and then he doesn't have to worry about it. I.

D

Don't know I, don't know if it's worth doing it that they're either level cuz I mean there can be more efficient by just using positions right because it doesn't need to start more than one, because.

C

The problem would be the reader yeah, so when the reader tells me where a value is I then need to figure out what to do about that, including the notion that essentially value my.

H

C

I've never I've.

H

Never worked for sequins enough Connecticut. Actually, how I really do so if the country can be, let's save it, for your new sequence would be then say: the sequence is too large. We can't stow in our internal my database. Therefore we throw and reject this input where you cannot store any positions. No, but let's say.

G

H

Is two gigabytes or five gigabytes? Our database cannot store it today because all.

C

The images of all is right, he's saying we add a second int next to the current int, which is which buffer did that come from, and now we have a loan effectively. We have a long maximally. Why.

H

So it has another 40 bits, so you can break about any size. You own the sequence into its third segment index yeah.

C

It always supports student, thirty-one segments.

C

D

C

D

Yeah yeah: well, you have.

C

You you now have at the beginning of the parse method of you are still walking the read on those sequins chain. So that's something bought over 100 men.

J

It could be over bun in the worst case right with one bite, Six Sigma to it.

J

C

Could give you lots of one sentence.

J

Okay, we can. We.

C

D

The reader supports our beta P.

C

M

D

On some time, I use it all the time because, basically.

C

H

My question is: do we have to support it now? Okay, before that yeah.

D

So they're up to two things, one is this type: doesn't support.

H

Tsunami sequence: I would not use it that maybe it's not important right, like the push to remove dependency on just over the net, doesn't require them, because it.

C

Is it really a hardship for you to take your read-only sequence and move it into an aquarium.

F

H

Very large, you don't want at all right the larger get the worse. It is for you to use the dog rather than the reader. Well,.

B

I mean in his case he wants to avoid also to diesel as the whole thing, which is.

E

B

But but he is the thing right that can his example at one of the stuff was well I. Call it the image, facial recognition thing right: there are some things: I wanna do less and there's some things. I just want to expose to the user yeah to access right. The reader is really inconvenient for their users. The Dom would be much more well.

D

That comes back to well with I would not expose this reader directly to users, and that answer is probably also know. Why would you not exposed to them? Because the alternative to exposing a Dom is basically creating a lazy tree of some type ideas?

D

She would provide types when you think things, because so it's it's not the ideal world. So in the ideal world I will have a teacher that kind of works like the shaft acrobatic and that one's kind of solves all the problems. This is my idea. World and I actually want to meet with again, and then we started the discussion because there are you know world, we don't create types, so other SDK doesn't have any time representing the tree.

D

Do a method call, and we give you a thing like JSON: let's call it JSON dynamic element. The Jason dynamic element is almost like this time, except it supports intelligence because there there is an attribute on the returning value. That says this is my schema.

D

That would be awesome because it's super convenient. Supposing that a sense- and it just on the fly materializes the things that I should have user asks, so it would be awesome.

C

But would you actually use anymore scenarios because it sounds like what we were making circling around for the past? Few minutes is even if we make this API take a little sequence, the actual behavior or performance characteristics.

F

Or something might still be an appropriate for your specific scenario and that construction well so I. So.

D

I know what I just talked about instead and user-facing idea.

D

H

Saying the type that he were exposed to the user, which will be now.

J

This types together.

C

Right, but would you would you actually be able to use this as a backing type for whatever you preach out to your users? Well,.

D

You mean, for let's say: I, don't get that I provide this each other, so we can craft the tree yeah and can I use this one? Yes, or would you use the Amina because you know what small pieces I would not do this so the moment the data is complicated, like I, don't even know computer I'm now using the reader I'd like for small things and kind of words, but they have to write my own helper library to my house.

E

D

If you're, if you.

E

C

Gigabyte JSON file, so something that just doesn't fit enough like just like using XML documents like the first call of parts, is gonna be expensive. So in fact, does it work the whole thing.

D

Yesterday different something more usable than five gigabytes, all right, because five gigabytes, whatever likey, yes, it's gonna be expensive, no matter what we do right, one man, the biggest that I can support, is whatever whatever.

P

In that max value divided by 12, so.

D

P

One megabyte.

D

Jason, okay, it's very common and it's right! Well, it's 200 Packers to 250! So something.

H

Yeah so I don't want to come, I mean it was not good, but copying.

I

H

Not gonna eat that cancer into a temporary buffer. Then you Internet throw away one remaining.

C

H

Will you're sure.

C

H

It starts more um it just okay, tell me what you were saying: a lot of smoke a whole page copy, the page yeah yeah, so do already under the only sequence, this one megabyte it's not even asleep. That's the same as reading a.

C

Mile off disk, yeah, okay, here we go. It's.

H

Free, that's the point, so the larger the copy, the more expensive it is, but large copy you know, go you the parcel.

H

You mean the past better on the dog, yeah yeah.

D

So anyway, my scenario was I kept a one megabyte JSON file, I would I was thinking that they're finding the copy would would be beneficial and then yes, I, will use this time internally, have a facade of strong types and just from their properties referred to this one. Sorry so.

H

Again, my question remains: can that be added in the future like janitor? Can this be added in the future, in that there's nothing in the type def MS is providing it today like, but honestly, my my.

C

Guess, like just gut instinct, is copying the 200 buffers that make up of 1 mega. We.

H

Can do that only a fool will be faster than changing this to be that anyway. Well, I, don't want to do, is block curse, top scenario and also defer the analysis. So we don't have true gut feeling. We can do the analysis, but just as only deposit yeah, we can do away so also like it's kind of.

D

Strange we begin at this call no coffee and then the moment you want to find trace on the same way, not using that either. You have to copy well.

F

You have to you have to inspect. An inspection implies.

C

You go in a forward walk over the whole thing, honey. Well, the tentative move in code well, you're you're, building up a data structure which is effectively papi, yeah.

C

Okay, I mean this is yeah, so it's still, even if it does a copy for the Reno, a sequel scenario in the short, medium or even long term. It's still a different memory characteristic, the current J token, which is interprets that I use it every. Second, let me gives you the dynamic tree so.

H

It's this is even this is still cheaper right choice, it's about like incremental any cover that you get Y value later yeah, so, okay, so.

D

H

D

If we were how many percent sure that we can do it like there I'm fine, okay, the thing that worries me is it's gonna change, so this time that I worried that we will not be able to do it well, you won't have to redo.

E

The database I've.

D

Used something copy potentially to erase and whatnot and like right, but there's an intrinsic atomistic of the type not of our current API shape. Yeah.

G

D

As school, regardless right, no no.

H

Except it's also time of things right like either we just toward ship this feature until we have both I wish everyone now, because we need it now. I should think we don't need different enough.

E

C

H

The more tightly I would prefer for this type. Maybe it is going to handle customers even in the preview stages. You know they give feedback and we will do more person.

G

On board, and even in the.

H

Previous stages, see, we can add that rather than wait and spend more time in the design, because there's so many abstract consumers and they have requirements that are vastly different than even your requirement and you're, not getting any of that River right now,.

D

H

My concern I think.

D

Maybe that's fine right, I mean. Is it such a big deal? Is it's really a massive change? If you copy the buffers into an array, basically you did. You did like a light copy, so.

C

So I don't know what it takes to parse an instance across $2 I've, not read my third I skim dance on scheduler that so.

D

What is what is so? The constructor takes read-only siesta what it does it enumerates. The second area which I member here creates an array, data and stores by that's available. Now he stores in a database instead of in 32 yeah. He stores in 60 that also doable yeah, whatever he needs to find yeah data.

D

Sequence, he takes the high order, bits 32 indexes into the right that he has created and he takes the Lord bits.

H

And indexes into the memory, that is, why would we do that rather than accepting realistic was the way it is and read user needle the Vedas, because to read.

D

Minami sequence: to build the database, he needs to be able to refer to the data database. Easterns pointers, idol data. Well, the pointers we found this thing trick that I described position right so position contains an object and.

H

Which cannot be stored in binary and he stores everything in the.

D

Difference is while.

H

You're reading using the reader, you can keep track of our segment array and stole. Then the database for you to do an upfront and then refer to the slices of sequence. Val reading is slow because every time you gonna say give me the second slice given third slice. So you as the reader you just get the sequence. I know I get what I'm saying I'm saying the database can store an extra eight tell you what segment you are in, but that should happen while the readers reading not a problem well.

H

But then, when you need to.

D

Enter a time, let's say now, I'm referring to you, know, I I'm searching the database and I'm referring to data. Now you wanted the get int method and, let's say every time, I call get int. It happens to be the last segment now every single access or is walking the whole train.

H

But you, your suggestion, forces the parser to do that all the time, no just one time when what API.

G

H

Really sequence: do you call with the index saying I'm in the tenth segment you built an array contains memory yeah, the only sequence we don't need.

D

C

H

See so you're not use the do a sequence, it has it all and we.

C

Actually need this or the ones whatever came back, if you have a string that goes across like a drums, I don't need to know that so.

J

Your impending, an array of read-only sequence segment right, yes,.

H

J

Then I threw out the original sequence and now you the thing.

H

You're allocating is this cost of sighs. Well, it's not constantly small.

D

H

D

That's it just if you.

H

D

That this feature is so destructive that you cannot spin it in the schedule. I think it's fine to this. One is now this I can tell you with it. It like it doesn't change the.

C

Discuss it right, but the but I it.

C

So I can investigate that. I can see if I can take that one.

C

Alright, so we're dropping triquetra value. We're dropping, try, copy wrong value so far, we're adding in other parts that take system string and if we can make the read only segment work, then we had a parts that takes rid of a second meiotic.

H

C

I think ultimately deferred that I thought we said we were going to do it and we were going to transcode. It was comedians. I thought, that's what even said you wanted. Yeah. Okay,.

D

Yeah by the way, one more thing you can move on, but you know in question all the buffers a single array: okay, so they actually allocate one massive area that they slice it into. 4K usage on yeah.

K

D

Don't know how we could get through the kind of back door, but we could just use along and just index with all this holiday. It's maybe just want to you.

D

Know see you saying like if we jump through basically values spans two segments and.

C

They only ask the operating system, for you know, 128 K and then gives you 16 bytes, the next 16, but it's not necessarily the okay.

C

So just a little me only in all of our missions, just asking okay, they only lives in the process document.

H

Being disposable is fine yeah, so does anybody think it's weird? The documents goes away. Steve I, don't agree, didn't.

C

You have resources that you're give you know if it's optional, it's fine yeah right, yeah I mean what you're doing is you're stealing gentle buffers from the Oracle okay, oh you're, you're, reducing your applications.

H

Performance, but you want to do it. One concern I have is the named Esther element. I thought it should be connotations okay, so she says we have JSON token type and JSTOR tennis. J token element is more XML. Well, we cannot change it to be this type. That has three.

D

H

D

See they're object, array or value yeah, it's non three. So now it's object, array string or.

M

Number or no to.

H

Work also on the body. No, no, but he's saying that we got changed this just elevate to him three modes: we don't be not returning type as this one don't achieve a return type. As of the very end of object, array, string, number 2, saying.

C

The value interacts well Oh.

H

D

You need to know what that is before you can call the number right.

P

C

Know it's a string before you can call the string you like.

D

That, because it.

P

C

Yeah, it is all of the things from Jason token type aghh summit, in the object and in the right exactly the things that that don't make sense and start object and start array or rename of this. It's the winner is basically right.

H

Yeah, the other thing is element is more XML and token. Is this rifle program, so we should call the type jason token well,.

C

Now the question is: are the users of this people that are already familiar with jason, that men are the people that use this the ones that are familiar with our existing.

K

Xml, it guys I think regardless it should match the existing or jason, because, if anyone's going to be learning about it, new and researching Jason stuff they're going to find token for everything. But.

D

K

Knife is not makes you do is.

D

Actually it it well, it's a Samson. It.

C

If you will have an object or an array and in James's api have the same, glossing over the details exactly.

P

C

A token is a single element has processed by a parser in.

H

Fact, the bottles of always this instance of this thing would not be a token right. That's good.

D

Use the parser.

H

Terminology of tokens, as in think that delimiter, so the adjacent specification calls it either an element or a melding. Okay, then that good.

C

So that seems element is the union of element in value element is a value potentially with surrounding one space yeah. So it sounds like the spec says that element: okay, I, don't.

H

Know, sir, okay, no.

C

Element really doesn't matter. Thank you, okay, so next for all the numeric types, I have tried to get value. That's based on at least but I. Remember the feedback being from changes to the Reader API Steve when he was looking at an early version of what I had he even changed his mind or on how he felt about that. If he now thought it was weird that we have tried get value, there would get n32 get at 64 that you went to keyboard.

C

So if you suggest that they go to try the thing that they are biker and will do doing, demos try to get value out into returns false if the number is bigger than it's about max value, or has it really as a religion or so it does not partisan.

K

Enter why no you in 32 I can edit and what about float? Because my work with you.

H

G

I mean the read, expose it, so this is okay.

C

So we can even add whatever we want I went with. This is the standard or what seems to be the most common of the standard things that the floating you know, the the double, because it's more precise in two, because it's what people want long for bigger range and you long for if you, if you need.

K

That pipe it, so the only reason you would want to add flow instead of just having double is because there are values that wing parts as a single will be different than when you parse it into double and then cast down.

C

We think it's important, we can add it. If we think we want to wait into, we have customers, we can do that. Do we have try get data and stuff. You know in the video all you you don't have it the reader. So I don't know here, because.

J

Just what what if the value smell the.

C

Value in the Jason payload is the literal token in ull, yeah.

Q

So it's a no, no, no gladly, then the token type whatever.

C

That turns into will tell you what is known and every other methods growth except to okay, should.

L

They be nullable values of these try gears like it, get double and get nullable double, and if it happens to be a null.

Q

Token then, a returns now I, so personally, I. Don't think that there's value in that.

C

Because it's an easy extension for someone to do with a scenario that I don't think that I would ever have in any code that I would ever write. But certainly your.

L

Jason out there, though, and there's a lot of case somewhere FFA representing and missing value, they'll, just put on a put a null like I, quite often see people cast like these. These helper methods that you have the way they generally work with Jason donators I have explicit cast operator overloads, and you quite often see people cast what could be a null value to a nullable and, for example,.

C

So but you you have operators so to do that. Garage, yeah,.

L

I I have cast so I have operator overloading, let's explicitly so.

C

As long had that in his prototype, I took our framework guideline rule which says that we need to support languages that can't call conversion operators and therefore we need to have named equivalents of those operators and then Steve looked at my thing and asked why why I'm bothering having both? What's the scenario for explicit casts because everyone hates writing explicit, casts so then I drop them, but we can add them back in.

L

Operate over those so I'm, more thinking about a scenario where someone has no coming back from okay, they have say, for example, I, don't know like age. For some reason, age might be null in some case, so they want to cast it to. They want to convert that to a knowable end like right now they would need to, rather than just call it get knowable 132 that need to look of a type, isn't no okay return. Now.

H

To see is the type number and then.

F

H

Dragon value, boo, double or intro, etc, if you're using the dominant ones right yeah, but.

C

Calling cracka done, I can. I can almost guarantee that in five years time, which we woke up any example.

H

So so Ben would someone.

C

Less than one percent of people trying.

H

C

H

That they'll call it blindly, so I don't even know if anyone will call try get now you. So that's what, if someone's I get it first gonna do. If type is number number then called I get mad. Okay, maybe.

C

I mean the reason you you try to get value is in my head. Is you really really really really really hope that this is a 32-bit number, because you might be running on a 32-bit processor and don't want to do double register consumption, but damn they gave you a number bigger than that max value, so try it all.

H

Okay, so let's see what the premise is true that the football racket value you gotta use your check on the type and the type is null you can you have the check already, but.

C

Again, I, don't think that in my scenario, you know it's a number, so you're gonna call try to get value and just let it throw it. It's the wrong type. How this graduated through try get value only returns false if it would, if value would throw a format. Exception throws an invalid operation exception if you're asking the wrong question so.

H

But now you've been unable thing you're, forcing the user to check the return of the return value of the.

G

H

To know so, then, maybe better to say if type equals null another, what eigen value I know it's not else. Claude drag event, sure I.

C

Think if you were expect like the question, is how much do we think people are gonna expect multiples if they do lots of people are writing that code and they do a missing a feature if it's very rare than that.

H

Code, but rather than doing crack in value return a little. We have the type token type which the user should check up front if it's null and so right now there's. But there.

C

Is that the question is, is if that's a common operation, then we should hold that input. One.

B

On well I think to me, like honestly, the Dom makes a lot less sense. If you really don't know the schema, if you really don't know the scheme where then yeah, you would have the similar pattern that we have individual, but you check everything right wrong again. A more common pattern is you expect a certain schema and you just don't want to blow up of arbitrary exceptions in the middle of your code. You just want to handle it in same cases, in which case you idea.

G

B

Wouldn't make it so that you say well similar to this I expect this video to be there. It might not be there either because it's optional, it's just you know somebody didn't follow the schema correctly and I would I would treat like Vedas. The same thing like I expect this to be an end. If it's learning in because it's an array like somebody shut up but I, think in that case, I only sit would say, try get videos right into it or just return, false and say yep.

B

You tried to passive in but sign in something else. You'll know what it is where you can check.

G

K

B

K

B

Exactly matching the semantics we are recited on for the reader, yeah I think the reader is different in that, like you need, like you, expect the reader to be people never expect a certain scheme, and they just to just always switch them. Everything like so.

G

C

Region, which is not.

G

The case here right so the.

C

Framework design guidelines for a tribe method, one of the many ways of interpreting Christoph's, very vague statement- is that every caller needs to have the same recourse if it returns false.

C

So if, if you're calling tried yet in 32, not knowable and it returns false, what are you supposed? What is the expectation of what you're going to do if we grow? If it's not a number, then the obvious thing that you're going to do is try a bigger number or try a double, because maybe it was a floating-point number. If we make it return false, because it's not a number or it didn't fit. Now you like you're in a very ambiguous.

G

Statement yeah, oh I, don't think so, because I got because I expected my spirit to be an interior, the recourse for that. If.

B

It's more than anything, I just returned different suspect.

N

B

In we call get it 32 and.

N

Let it go it no I. Don't want them to feel because I'm looking for a different exception, I don't want to handle that exception, because well.

C

N

Me everything different exception: I.

L

Think we're we've gone off track where we're talking about unexpected schemers, like it's really common for people to take a C, sharp type which happens to have a nullable boolean on it or nullable, internet and serializer to Jason on one end of your API and on the other end they want to read it. So it's quite common that you might have that boolean or sometimes true, sometimes false and sometimes no I, just think it's worth having a method on us where and one-one mythical, they can say, get nullable boolean rather than having to go.

L

F type equals null, then no otherwise get.

H

C

Right or no a boolean right, it's an array so return false right and I. Understand that and I just don't know that we actually have a convention on what the get would be called. Would we call it get in ull a ble in 32? It's not like. We can fun doing that, and so I'm fine like if James takes the scenario is common he's. Certainly do I would look to as a domain expert and we can certainly add the API I. Just don't know what to call him.

C

Also, would we add, get double Anakin, boolean I would take everything. I mean all of the things seemed string doesn't need the nullable version, because string is a mobile version, so we would just change, get string to say that it doesn't throw on the null token. It returns no I'm, an alt okay, which is fine. It's a scenario. I hadn't considered.

K

You don't return and then, if user type of requirement that it not be null.

K

It was no well there's, there's also the case of like they're, taking it and they're passing it somewhere else and they're not dotting into it. They're like displaying it or storing it, in which case they won't get an old record set, yeah I would I would rather.

H

Get another bus general we're looking all right because well.

K

Like in when c-sharp eight comes around and you have the explicit no, they might be important to consider. We've got one that never returns null versus. We have one that can be null.

C

I mean we have feature when it comes, will destroy PCL and I know it's coming, but I. Don't think that this will be the place that to start with how it destroys the detail, so that.

C

Mistakes: yeah, no because you mark the ones that should return. No, it's you sprinkle question marks not bangs. They decided the banging when is too shabby yeah. So as long as we have a name for what we do and that's fine, so then the question is: do we? Is it try to get value out? Which type did you want or we go with? Try get in 32 we try getting 64, etc, because we probably have done both patterns in the framework. At this point, it's a question of which one we think is the right answer.

C

K

Think when you can differentiate based on overload resolution, then you shouldn't include the name in that you should just have more pieces. Well.

C

But the inconsistency at that point is the get and the try gator not being the simple baguette.

H

Value and then getting can you do yeah.

C

H

C

Said returns about the man Steve's Steve's thought after he was looking at this example of it was wait that looks really weird that that the try that what I want to go from get to try that I rewrite more than just put a TR Y or the other. It's like yeah. So don't some breaks of the cool.

G

Want to use of are well.

C

Honestly, I love anything that breaks the use of the part.

G

But this is at the point of a bi yeah. That's the point of being on FX DC is to steer people toward things to pull off our work. I.

B

Think the I think the question is more like I, think for for us or analogy I would I would treat them like kind of like return types, which would mean there would just be overload similar to the other ones and I think the additional consistency between try, get and get is I think actually useful property to have so.

C

So you think give it 32 and try get in 32 yeah and we.

G

C

Retroactive ly apply that feedback to when we either to change it in here. So now don't change it in the readers. Oh good, you've never committed above test teachers of comedy you've changed it and unchangeable right, good.

C

Right so aside from the child enumerator, which will get duplicated when I make a different one for array an object. The last thing we have here with about 30 seconds to spare is to overloads on the writer, so they can write an element. You already have a fully formed element and you want to just write it down it's up to a something. If he wants to respect this object is already an object or if he wants to walk the tokens for spacing jason writer api see ya.

C

Once we take Jason once you can never have adjacent element, that is a property. Once we make the new jason property type. We may also want right property that these jason property, because acid and I had discussed what this would do for right element if right element was a property, it would rip the name off of it and call the other knowledge. We should add boo. Some.

H

Friends escaping for the right elements that dick string, property, name okay. Is that what we're doing on the rest yeah? I.

C

C

Even make sense to they can I think ask ask songs, didn't because it was in a restaurant, yeah, yeah row grukk struck you're down the water life, but.

H

This is not electric anymore, so we.

C

Could add that yeah it could be done? I mean.

H

C

Will, if you try using it in one it will box.

J

L

Speaking alone, speaking of link linking over the JJ token, Kop are a that's us pretty pretty damn common like that was the original intent when I first made them and I saw schleps. The name went to links JSON since back in 2008. That's what everyone did. I think and numerate children method like it's gonna, look a bit ugly! When people start doing link will want to do link with Jason element. Has it been any thought around that and.

C

K

Properties or dog values, why is it called enumerate children as a method, rather than just children as a property like I.

J

Guess it's no more.

K

Operations world we.

B

Could be a which do we have do the same thing, that relaxing.

K

Elf stuff, we just call it children and then a it's.

B

K

Numerator that won't new marry nothing if it's got no children, no.

C

I mean it's not so. Elements can have no children in XML right, but can you enumerate the children from an XML attribute like.

H

That doesn't really make.

J

The difference is.

H

That you're flattening the we don't have Jerry J value, J property yeah. So this exists on all tokens yeah and that's why a 12-8 earth rose on number yeah when other cases we had two separate types, so you didn't have a numerator on J value and maybe it's okay for.

C

For them to throw here or on a dummy.

C

L

And ingest net J token is enumerable, which means he in a weird situation, we can have a J value, which is a boolean which, for some reason, has innumerable on it right and I believe I throw an exception, I'm pretty sure I do. But, although it's a little weird, it does make link very easy. It makes it easy to just say on I've: got an object: I go into the property name on it. So, for example, I might have a personal object mean it's got hobbies, which is in an array.

L

I can just go person, minindex and so hobbies, then, just for each over that yeah and it's quite a clean and concise way of doing link. I'm.

H

Just wondering should.

L

Chase an element implement ienumerable.

O

A

J

Verbal of watts of.

L

Jason element: okay, but that wouldn't work, I, guess if you're not treating properties as Jason elements, though, because when you for each over a object, what would get returned would just be the value? Is he kind of you can't paint the name yeah.

C

Well, we had spoken earlier about dividing this up into two different Eva, where there's.

L

Something something which I think might be useful for you when you're designing this and building this, as with the Jo ara and friends and Jason on it, is I, have a whole bunch of samples on my website like I. Think it's it's about thirty or forty I would recommend, taking a look at those and seeing what the code would look like with this new JSON document and even seeing whether some of them are possible like because this is read-only and you can't use it to construct.

L

Jason I think, probably maybe a third of them not possible already, but a lot of them have to do with veteran values and querying values and I. Think I'd be interesting to compare them side-by-side and see how the syntax would be different and I thought you would be losing by using this to structure, structure, syntax, an API.

K

B

They would basically be they check the type kind of thing right, I think he's saying return false if it's an array and has.

K

And also if I did not have that, so it's different than can have.

J

Children, yes,.

K

J

K

I have children and so enumerate. Children will actually do something versus it will either returned nothing, because it's an array with no children or it would throw because it's a number in can't have chills. Okay, yeah.

B

I think the one thing I was like I, just looked at excellent exting doesn't have any properties, it's all methods so like if you want to throw, we can still to all it just seems very weird. The other thing is the next thing. The way they solve the problem is that the gist of a hierarchy right yeah they have basically ancestors, were like they don't have children, they have nodes and they have elements right which, if you are on an element, like notes, will include the attributes versus elements will not.

C

I want to correct my statement earlier, like the newer versions of the JSON specification.

J

Don't use the term element the return value, the older versions and I looked at musicology. They they don't use the term probe in.

L

J

Is what I made.

L

Up because I didn't like element.

J

C

So the Jason spec.

J

Actually does define token as a grandma like braces, right, I. Think back to the posture.

J

C

H

I was gone: did we undo the separation? No, the concern was why we have a method and in link it linked. Corey's would look odd, because now you had a method call and one of the concerns was we have to throw. This is why we don't make a property. You know, because this is a collapse flat structure rather than higher and.

C

James was also adding more you around like why? Don't we just make a snowman or.

J

We could say: I have notes for men which really noisy collection and is an.

C

Either it's not meaningful to ask if I have children right or it is meaningful that I happen to be empty.

C

Certainly get a numerator with Rose yeah because you're the wrong thing, then you look at the C sharp and it's the problem with the for each statement in C. Sharp is the method that you didn't call his went through yeah and you look but I have value.

C

C

We're starting to talk about.

H

C

K

It's fine, but as children property, so users can easily track if enumeration is worthwhile or enumeration will throw I think about that way. You can avoid avoid it without having to in remember all the token checks yourself yeah. That's just it.

B

All right so I just submitted the PR, so I'm done taking notes and I think we've done for today.

H

Did you add yeah.

B

I I did add the link discussion. I am to it, which I think requires somebody to design it.

C

You have to get the right length for Jason today. Why is there a concept of get property count for about that? No.

C

Because you can't index into then buy or no value, okay, I guess. The only the only time where that might ever would make sense is say that I want to I want to externally create an array in Jason property, yeah.

K

C

To know how big decide but I think.

K

That you're creating your own collection and you one.

C

Yeah that could first of all, that could always be added later. If someone who really cares right and I could always just usually can say like doctor, oh yeah, so we certainly we know or can know that data. We gather more data during parsing and we added weird and certainly so, I guess one thing that didn't come up. All of these investors find me first property of Ameen yeah and if you have James.

G

Finds the last one.

C

Because he uses the dictionary, the dictionary says: that's right, Irwin for a linear scan, so we find the first one if you have multiples and you're storing in the dictionary you end up in the end with where you told me, there were 12 properties. Why is there only one thing in my dictionary, it's like because they're all named the same thing, his.

B

First, one wins really in there I intended you I would actually just.

C

B

Reason they learned everything well.

C

The reason being that if I have code which is using Jason's on that- and it smells to me that and I request- please give me the value for food and it says hello and then I use this and I say. Please give me the value for food that says goodbye like that's a problem. Well,.

K

And we had the same issue with in the review where they for their native.

B

K

They've got things and I think they returned the last well.

B

I mean I think last usually makes sense if you have all rights in right. The most common pattern is command line. You just suffix the command and you want to just make sure the value is X. So I don't care what somebody else specified before for X. No, it's going to be X right, so I have no idea how Jason works, but I would assume if you treat this, isn't as a do civilization font of JSON. If you do still has it on the JavaScript side and pretty should last one videos.

C

C

K

Would vote that if it's ambiguous, we should either fail or we should try to match what everyone else seems to be doing. Yeah.

J

Because not matching.

K

What everyone else is doing is.

K

C

Property reading to read the entire table well,.

B

That's exactly for performance point of view. That's bad I have been get.

K

First, if they want it, otherwise there's other ways to work around them.

C

A

C

We're building up the table, I, don't know what string in I know that the token that they told me that it read a thing called property name and it started here and ended there. That's all, that's literally all I know makes sense.

F

G

Then this indexer is turn.

C

It into utf-8 and and call a sequence, equal a task visit is that you get a stream back. Don't you from me Jason where you go? No, because you're I, guess man, you get a stand, but the stands going to be escaped correct.

C

What what do you are you calling on the Jason River to get the property name correct.

G

C

Measured values pandas escaped correct. This needs to escape going in well.

J

It is an you're, not unescape, Nima jason in values, family, I'm leaving the management of.

C

A what's the can't.

J

C

Projected yeah okay! So you all what you already have to do: text analysis on yeah all.

B

Right, I'm, hungry I call it a day they're still streaming, though,.
