06:27:24leorizecheck out those new features :P
06:27:46leorizealso the chronos vs. asyncdispatch is going to be properly settled
06:34:09Zevvoh, how is that

06:39:02leorizeZevv: I guess that's how the fight has always been settled: both sides forget about it then move on
06:39:56Zevv:)
06:43:44AraqI am writing a new RFC, "stdlib v2"
06:43:57Araqwith design guidelines
06:44:02Zevvnarimiran: wow, no computers nearby. I should try that. I'm currently on a little island, but i did bring my computer. I do read tons though
06:44:34Araqand it will be a collection of Nimble packages. So yay, replacing old mistakes by new mistakes
06:45:14leorizeas long as I don't have to build nimble before I can build Nim, I probably can live with that

07:01:02FromGitter<alehander42> guys , do you prefer shortcut => command, or command => shortcut configs
07:01:16FromGitter<alehander42> do editors use mostly one of those or the other
07:01:26FromGitter<alehander42> Araq: new stdlib sounds awesome
07:01:33leorizeAraq: is `lent T` an automated transformation?
07:01:52FromGitter<alehander42> would it contain common "interfaces" / "protocols" to which some of the packages to conform ?
07:02:25leorizemeaning that the compiler automatically optimize stuff to `lent`?
07:02:32FromGitter<mratsim> Araq said that we need working implementations to have working interfaces
07:02:45FromGitter<alehander42> ok, but this is
07:02:53FromGitter<alehander42> v1's libs + current packages

10:47:53clyybberAraq: Elements of an array constructor should always be treated like sink parameters right?
10:48:24Araqright, it's even covered by the spec
10:50:02clyybberWell, I've found a problem with that.
10:50:11clyybberI think
10:51:11*abm joined #nim
10:51:46Araqwell?
10:52:03clyybberI'll send a snippet
10:53:40clyybberIn twidgets_unown.nim there is a leak introduced by my PR.
10:54:08clyybber#devel produces this transformation for draw: http://ix.io/1Rov
10:54:26clyybberWith my PR it produces this: http://ix.io/1Rou
10:54:38clyybberAs echo has varargs
10:54:46clyybberand thus introduces an array.
10:55:48Araqhmmm
10:56:37Araqlooks to me that array construction must be smart
10:56:49Araqand see whether 'echo' uses a sink parameter or not
10:57:39Araqlet a = [arg1, arg2]
10:57:51Araqecho a # meh, ok, 'a' sinked the stuff
10:57:53Araqvs
10:58:17Araqecho [arg1, arg2] # don't sink. And don't copy, it's just some syntactic quirk ?
10:58:38Araqyeah.
10:58:58Araqit's conceptually really echo(arg1, arg2)
10:59:14Araqand for ordinary, non-sink parameter passing we neither produce a copy nor a move
11:00:18Araqit's a special rule but at least it is not echo-specific
11:00:29Araqand rather easy to detect in the AST
11:02:43Araqclyybber, what do you think?
11:03:21clyybberI'm thinking..
11:03:37clyybberAraq: How to detect if it was varargs though?
11:04:28Araqit doesn't matter, the pattern is f([...])
11:04:56clyybberYeah, but that will break what I fixed, the `@` proc
11:05:11clyybberI think
11:06:07Araqf([...]) --> handle it like f(...) but keep the nkBracket

11:42:21Zevvdisruptek: I think I got the most simple setup for importing paterns and doing name lookups. I'd appreciate any feedback if you have some time one of these days
11:43:17disruptekdid you push it?
11:44:49Zevvits in a branch, but the basic idea is very simple: all patterns in the global library get fully qualified names <libname>.<pattname>, and all non-qualified pattern names they refer get qualified to their own libname.
11:45:02ZevvWhen you want to use a pattern from the global lib, prefix it with the lib name.
11:45:05ZevvThat's it.
11:45:21ZevvSo you can now do 'net.ipv6address' in your grammar
11:45:37ZevvThe whole importing I leave to nim by just using normal nim files which you can import the normal way
11:45:48Zevvso no explicit imports needed in thet grammar itself
11:46:10Zevvthe global namespace will probably bite me one day, but for now this is cool
11:46:39Zevvjust pushed to master - it should not break anything
11:46:42disruptekit sounds simple but i don't get it. :-D where does `net` come from? not the `net` lib.
11:47:00Araqalehander42: it comes up from time to time but there is no concrete plan to remove the libc dependencies. For Windows I can do it
11:47:09Zevvdisruptek: no, that would be a npeg/net
11:47:09AraqI mean I *could*
11:47:39Zevvto-be-written, just an example. I plan to offer npeg/uri, npeg/net, npeg/http and other obvious candidates
11:48:07disruptekah, i see. so if i author my own pattern for import/export, how do i reuse it?
11:50:06Zevvdisruptek: ttps://paste.debian.net/1095444/
11:50:44disruptekawesome.
11:51:11Zevvcan't make it any more simply I guess
11:51:13disrupteksuper cool, can't wait to see what people come up with.

12:09:34disrupteksweet, i need that. it's crazy, but i can't find a simple tool to pluck addresses from an email.
12:10:15FromGitter<alehander42> Araq the point is to remove it for *some* subset of the stdlib i guess
12:10:42FromGitter<alehander42> i think thats usually useful for osdev/embedded etc, but not an expert admittedly
12:11:01leorize[m]Zevv: that thing is MIT licensed :p just that i didn't release the source
12:11:20disruptekZevv: maybe you should make a web-site where people can input their npeg and get back a js module for matching and captures, etc. i bet that would be popular.
12:12:08leorize[m]well I can do that now but that parser is the only salvageable part

12:13:15Zevvdisruptek: haha, that would be a pretty cool :)
12:14:36disruptekit really would. and you could somehow ix.io out the grammars and let people mix-and-match from grammars others had construction. let your library of grammars grow organically.

13:28:25Zevvso you can parse and store in and object, or build some kind of tree. you'd have to do the tree handling yourself though
13:29:18ZevvI tried making this part of the parser so that you can build some kinde of node T, and make these part of the capatures tree, but that broke too much stuff and i was not able to make this fit without smoothly
13:31:38*jmiven quit (Quit: reboot)
13:31:58Zevvthe pattern libs are also not really usuable as they are now, as these predefined grammars do not capture anything, and you can't make them. but I rather ignore that problem for now and just act if all is cool, maybe the problem goes away then

14:34:23clyybberAraq: You mean the varargs array is a "partially materialized object"?
14:38:07Araqsure
14:38:44Araqyou can generalize the idea to object constructors and anything that is only plugged together for the duration of a function call
14:42:32*solitudesf joined #nim
14:44:18Araqit's related to my .cursor idea: you don't have to construct an object properly if it doesn't "escape"

15:09:28disruptekso any part of the function env can be loosely constructed as long as it doesn't have a lifetime outside of the function? what about calls that function makes? that's an escape, right? or can it be bearded somehow?

15:19:41stefanos82so where is the database located?
15:20:58disrupteknim should probably reserve the %< scissor operator for some common operation. :-)

16:09:43clyybberAraq: The issue I'm trying to fix. It would be wrong to fix it I think
16:09:48disruptekin `case x: of y: ... of z: ...` how many colons is the right amount? most of stdlib appears to omit a trailing : on the `case` line, but i guess nimpretty isn't opinionated? https://github.com/nim-lang/Nim/blob/devel/lib/core/macros.nim#L1215
16:10:18clyybberAraq: I mean fixing it in injectdestructors
16:10:29clyybberBecause I think the transformation is correct
16:11:00clyybberits just that @ does things that should not be done.
16:11:07leorizedisruptek: the trailing colon is an optional thing f
16:11:12leorizefor "consistency" iirc
16:12:49disruptekyeah, i think nimpretty should take a stance on it, either way. i personally use a : on my case line. also, with respect to indenting the `of` clauses, with and without indent seems a matter of preference.

16:35:09disruptekwant a pr for nimpretty?
16:35:11Araqis the one true way (TM)
16:35:58Araqwell nimpretty needs a --onestyle vs --mystyle distinction
16:36:05clyybberYeah pls
16:36:35Araqeverybody wants the --onstyle as long as it's --mystyle, but *shrug*
16:37:06AraqI've given up on this nonsense, I accepted that programmers are fascists
16:37:16clyybberNim makes it easy to not care about other ppls styles
16:37:18clyybberso thats what I do
16:37:50*shomodj_ quit (Quit: My MacBook has gone to sleep. ZZZzzz…)
16:38:14AraqI am using a generic solutions, I only read books by Terry Pratchett
16:38:32Araqcan't read other books, the style isn't the same
16:41:55clyybberAraq: `@` takes ownership over the array it gets
16:42:06clyybberOr it *should*
16:42:17Araqclyybber, so give it a 'sink' annotation?
16:42:29clyybberAraq: Yeah, and that will fix all the problems I think
16:43:00Araqwhat about let x = @[f(), g()]
16:43:04clyybberMy point is that I have a suspicion that `@` cant work without sink no matter the rewrite rules
16:43:29Araqwell if @ needs 'sink' then our design has a bug
16:44:20clyybberAraq: Ok, imma eat for a bit. What should `var x = @[@[Foo()]]` be transformed to in your opinion?
16:45:06Araqto the very same
16:45:26Araqbut var x = @[@[a]] needs to copy 'a'
16:46:16Araqah!
16:46:32Araqyou're right, @ is like an imported proc that doesn't play nice
16:46:55Araqand so it's not a bug in the spec.

17:26:42leorizestuck?
17:26:45clyybberHow did you get stuck?
17:26:50Zevvi forgot the exact error message, it was something like "needs a copy because it is not the last read"
17:27:03Zevvand I didnt know what to do from there
17:27:10clyybberAh
17:27:25Zevvwas inside a recursive function iirc
17:28:20clyybberZevv: Owned refs cant be copied, so `x = y` is invalid when x gets used after the assignment

17:30:15clyybberZevv: Tell me when you're stuck, I might be able to help out
17:30:35Zevvit does make sense that the whole jsonnode tree would be owned, right? It is a proper tree without cycles, so that should be just fine
17:30:49clyybberAraq: Ugh, ./koch temp just stopped working. Generates invalid C code..
17:31:51leorizeZevv: yea
17:33:48clyybberGreat. Changing `@` broke bootstrapping
