| <Cube8> | hi guys! For my degree thesis, I need to find the buffer containing plain javascript has been executed from the engine. I'm looking for a pointer somewhere in the v8's source code to that buffer. Have I a chance to find it? |

| <jwolfe> | aklein / littledan__, does this intent to ship look good? http://paste.ubuntu.com/23793652/ |
| 18:53:21
| <littledan__> | jwolfe, looks pretty good to me; for compat risk you may want to clarify, "was previously a SyntaxError, therefore compatibility risk is low" (theoretically someone could be depending on the syntax error) |
| 18:53:45
| <littledan__> | is it shipping in other browsers or just implemented in them? In Stable yet? That also feeds into the compat risk. |
| 18:54:44
| <littledan__> | the summary could be a little clearer to explain that you can call a function which was not declared with trailing commas using a trailing comma; it could also use a more sympathetic example, with long parameters on separate lines. It doesn't need to be exhaustive about all the places where trailing parameters come up, OTOH |
| 18:54:56
| <littledan__> | anyway, those pieces of feedback are all optional; it wouldn't be bad to mail as is |
| 18:56:19
| <littledan__> | IMO it'd make sense to mail these sorts of intents to blink-dev in general, as that includes an audience who is interested in changes to the web-exposed surface, though cc'ing that list is not required and case-by-case |

| <jwolfe> | aklein, did you test trailing commas in Edge? I don't have access to any Edge installation to test this. |
| 19:20:10
| <jwolfe> | aklein, our feature dashboard that i believe you created reports that Edge supports trailing commas in functions in stable. is that right? |
| 19:34:35
| <jwolfe> | littledan__, is this summary too long? http://paste.ubuntu.com/23793925/ |
| 19:34:48
| <jwolfe> | i also optimistically reported that it works in Edge, but I'm not sure about that yet. |
| 19:35:32
| <aklein> | jwolfe: I got that from the kangax table |
| 19:36:02
| <aklein> | outside of stable releases, everyone but v8 supports it (based on local testing) |
| 19:36:34
| <aklein> | jwolfe, littledan__: I'd bcc blink-dev, yeah |
| 19:36:46
| <aklein> | if you don't phistuck probably will :) |
| 19:36:55
| <jwolfe> | aklein, why bcc instead of cc? |
| 19:37:50
| <littledan__> | jwolfe, I like the new email contents, ship it! |
| 19:37:50
| <aklein> | jwolfe: to keep followups on the v8 side; I see the blink-dev part as an "FYI" |
| 19:38:16
| <aklein> | jwolfe: but as I said what we really need here is just an actual process (which I mentioned to [email protected] in my meeting with him on Tuesday, it's a goal of ours for Q1) |
| 19:38:36
| <littledan__> | good to hear! |
| 19:39:23
| <jwolfe> | littledan__, thanks for your patience. i get that i'm doing optional stuff, but i'd like to spend some extra effort on this for the sake of learning. |
| 19:40:11
| <littledan__> | jwolfe: no, I was not criticising you at all, this looks like a real improvement and I'm glad you did it. "ship it" was encouragement towards this intent email contents |
| 19:41:37
| <jwolfe> | aklein, is this the kangax table you're talking about? https://kangax.github.io/compat-table/es2016plus/ |
| 19:42:32
| <aklein> | jwolfe: that's the one |
| 19:43:15
| <jwolfe> | ok, and so i'm sending this to v8-users and bcc blink-dev? |
| 19:43:36
| <jwolfe> | no v8-dev? i guess they already know? |
| 19:43:49
| * black_13 | joined |
| 19:46:30
| <aklein> | that's the idea, yeah; this is basically "hey embedders the thing you embed is changing" |
| 19:47:04
| <jwolfe> | cool. sent |
| 19:47:49
| <jwolfe> | now is there some timeout to wait before making the change that enables the feature? like 2 weeks or something? |
| 19:49:40
| <jwolfe> | uh. i suppose the email didn't go through. the delivery failure message i got suggested that i need to join the group before posing to it. |
| 19:50:11
| <black_13> | embed thing? |
| 19:50:18
| <black_13> | how is it changing |
| 19:52:56
| <black_13> | aklein: how is changing. how do monitor what is happening with v8? |
| 19:56:28
| * bradleymeck | joined |
| 19:56:58
| <jwolfe> | ok, i don't think i know how to send an email to those groups. i suspect the part after the @ is different for v8-users and blink-dev. |
| 19:58:53
| <jwolfe> | black_13, that's a pretty broad question. you could try https://www.chromestatus.com/features or https://bugs.chromium.org/p/v8/issues/list to start. there's also probably some release notes you could find somewhere. |
| 19:59:42
| <black_13> | ok. |
| 20:00:02
| <black_13> | i have been reading the embedders guide but it seems dated |
| 20:01:19
| <black_13> | i have tried to following this https://github.com/v8/v8/wiki/Embedder's-Guide |
| 20:01:25
| <black_13> | but i think its out of date |
| 20:06:52

| 20:08:10
| <aklein> | jwolfe: sorry that's confusing: [email protected], [email protected] |
| 20:23:30
| <caitp> | I think you need to subscribe to the lists in order to send emails to them, don't you? |
| 20:27:08
| <black_13> | i see |
| 20:29:44
| <black_13> | would be nice if the point example was updated |
| 20:35:30
| <aklein> | black_13: is there a particular part of it that's not working? |
| 20:36:56
| <black_13> | is FunctionTemplate::New the starting point of any work you will do? |
| 20:39:18
| <aklein> | not sure what you mean, it's the starting point if you want to make a function template |
| 20:39:48
| <aklein> | which is the starting point for designing a JS class hierarchy from C++ |
| 20:43:39
| <black_13> | let say yes |
| 20:48:44
| <black_13> | aklein: this is excerpt http://codepad.org/LjVCMsTo from shell.cc |
| 20:50:44
| <aklein> | black_13: and how does what's there differ from the examples in the embedder's guide? |
| 21:05:01
| <black_13> | what seems to be missing is "point" or something that says hey here is the point defined when you say "var p = new point()" a new point will be constructed. |
| 21:07:12
| <aklein> | black_13: so are you saying the documentation is incomplete, rather than out of date? |
| 21:07:49
| <aklein> | in https://github.com/v8/v8/wiki/Embedder's-Guide#templates, there's an example of installing a property on the global object to expose it to script |
| 21:27:20
| <black_13> | aklein: thanks ... in that example "log" with "LogCallback" |
| 21:29:30
| <black_13> | there should be a way in call back function you can create an instance of a C++ object and associated it with a v8 internal |
| 21:29:42
| <black_13> | that you could recover for use at a later time. |
| 21:30:53
| <black_13> | i found this example ... https://github.com/joastbg/quant-js/blob/master/core.cc |
| 21:31:15
| <black_13> | but his example lacks c++ object creation. |
| 21:38:24
| <aklein> | black_13: https://github.com/v8/v8/wiki/Embedder's-Guide#accessing-dynamic-variables is an example with associating a new C++ object with a v8 wrapper |
| 21:39:42
| <black_13> | that is interesting but incomplete |
| 21:39:48
| <black_13> | it makes one point ... |
| 21:40:08
| <black_13> | it does not address "var p = point()" .... |
| 21:45:03
| <black_13> | aklein: this is closer http://web.archive.org/web/20150217015842/http://create.tpsitulsa.com/blog/2009/01/29/v8-objects but references v8 at version 3.x |
| 21:48:15
| <aklein> | well that guide isn't really meant to be exhaustive |
| 21:48:17
| <aklein> | the API is huge |
| 21:48:32
| <aklein> | I admit we could use more documentation, but I'm not sure it'd go on that page |

| <black_13> | fair enough and anyone who wrote something up was someone who had down time then got busy and forgot to update the github they had |
| 21:52:46
| * bradleymeck | joined |
| 21:53:41
| <black_13> | ok could you answer this how do you bind a name "point" to a function "v8::Handle<v8::Value> Point(const v8::Arguments &args)" this seems to be start of any work |
| 22:04:24
| <aklein> | black_13: the log example I pointed to does exactly that |
| 22:05:25
| <black_13> | sorry do you have that link again or is this on the embedders guide |
| 22:05:45
| <aklein> | black_13: https://github.com/v8/v8/wiki/Embedder's-Guide#templates |
| 22:06:11
| <aklein> | that example puts a reference from the global ObjectTemplate to your function's FunctionTemplate |
| 22:06:33
| <aklein> | which means that any Contexts instantiated with that ObjectTemplate as their global will have a function called "log" available to them |
| 22:06:42
| <aklein> | replace "log" with "point" and you have a path forward |
| 22:09:54
| <black_13> | what is the differnece between and object template and and function template? |
| 22:24:36
| <black_13> | while i am asking why does it take about 27 second to init the v8 engine can this time be shortened? |
| 22:25:12
| <black_13> | aklein: hey some success |
| 22:25:26
| <black_13> | it didn't crash and did call the construct operation. |
| 22:25:46
| <bradleymeck> | 27 seconds??? |
