00:00 | <rkirsling> | ljharb: ohhh I see |
00:00 | <devsnek> | shu: almost done with the CL |
00:00 | <devsnek> | just working on a weird assertion failure |
00:01 | <shu> | if it doesn't complicate the method significantly, probably fine |
01:43 | <bakkot_> | jmdyck: does your type analysis currently distinguish between Number values and mathematical values? |
01:43 | <jmdyck> | urg, that's such a mess |
01:43 | <bakkot_> | currently, yes |
01:43 | <bakkot_> | I am reviewing https://github.com/tc39/ecma262/pull/2007 and having the assistance of automated tooling would go a long way |
01:43 | <bakkot_> | we mix them up in a bunch of places and this PR fixes some but not all of them |
01:44 | <jmdyck> | it tries to, but has to give up a lot of the time |
01:46 | <jmdyck> | i suppose i could make a branch that tries to be strict and only targets 2007 for now |
01:47 | <jmdyck> | What sort of timeline are you looking at? |
01:48 | <bakkot_> | Eh, there's not exactly any hard deadlines, but this is our highest priority other than the stage 4 stuff and normative PRs, since it touches a bunch of things and keeping it rebased will be a pain |
01:48 | <bakkot_> | I ask because I am currently doing the review; I'm not going to finish it today or anything, I'm just catching a bunch of things by doing manual type checking |
01:49 | <bakkot_> | and it occurred to me that a computer would be better at this |
01:50 | <jmdyck> | wup |
01:50 | <jmdyck> | yup |
04:08 | <bendtherules> | I was looking at Array species and it talks about realm records. Is realm related to iframes in browser? Like 2 objects from 2 diff iframe means diff realm? |
04:19 | <ljharb> | bendtherules: basically yeah, an iframe is a different realm |
04:21 | <bendtherules> | Ok. And is it also possible in other common environments, like node? |
04:22 | <devsnek> | yep |
04:22 | <devsnek> | node has "contexts" |
04:22 | <devsnek> | https://nodejs.org/api/vm.html |
19:49 | <devsnek> | being able to use declaration in torque reminds me how much i miss it in js |
19:49 | <devsnek> | we should definitely add it |
19:52 | <bakkot_> | devsnek did you... miss a word there? |
19:53 | <devsnek> | redeclaration* |
19:53 | <bakkot_> | as in like `var a; var a;`? |
19:53 | <devsnek> | yeah but with lexical declarations too |
19:53 | <ryzokuken> | would the second `a` shadow the old one? |
19:54 | <ryzokuken> | or just reset the ref, so that it can be GC'ed? |
19:55 | <devsnek> | basically just modifies the existing binding |
19:55 | <devsnek> | there are some nice things you can do with that though |
19:56 | <devsnek> | for example `let { a, b } = c()` vs `({ a, b } = c())`` |
19:56 | <devsnek> | ts could use it for type rebinding `let a: T = foo(); let a: U = bar(a);` |
20:03 | <ryzokuken> | I see |
20:04 | <devsnek> | rust has this too |
20:04 | <devsnek> | its very nice |
