00:02:51fowlAraq how about making openarray targetable
00:03:33fowlSo you can define a converter for anything with sequential storage and a length
00:05:18EXetoCwill openarray be needed when we have working concepts?
00:10:58Araqyes
00:11:14AraqopenArray doesn't lead to code duplication
00:11:19Araqa concept does
00:16:11fowlhow about a meta type that does what varargs does when you give it a function to filter its arguments

15:06:39arnetheduckhi, if I have an imported c function expecting a pointer to an array of elements and a seq with those elements, how can I pass the address of the first seq element to the said function? (it also takes a length)
15:07:08def-arnetheduck: addr mySeq[0]
15:09:08arnetheduckaah.. now I see why that didn't work at first.. was using "let mySeq = @...", then it complains
15:09:26arnetheduckwith var mySeq it works, thanks :)
15:11:15EXetoCthere'll be something like unsafeAddr for immutable variables I think, which of course implies that nothing will be modified
15:11:41EXetoCthat will get rid of many instances of vars or "var x = x"
15:15:45drewsremIs there something in c2nim with which I can change the import path of a header I'm trying to convert to angle-bracket search-path rather then in working-dir? - i.e. I'm using "cnim --header types.h" I copied over from "sys/types.h", but in the produced nim-file I want "header: "<sys/types.h>"" instead of "header: types.h"
15:16:36arnetheduckEXetoC, any idea where to look? can't find it.. though, in my case, doesn't matter really, I'm converting from an openarray anyway
15:16:45drewsremOh wait, there's actually a c2nim user manual ...
15:19:42EXetoCarnetheduck: I said that in future tense. I dunno when we will get that
15:20:34EXetoChttp://forum.nim-lang.org/t/708
15:21:03EXetoCthere's a discussion about it
15:22:57arnetheduckright, missed the future - got it, thanks
15:23:20EXetoCd(:P)|<
15:23:47arnetheduckhm, looks like it could be useful with openarray directly as well, to avoid having to create a seq
15:26:11EXetoCwell, you're either passing in a seq or an array
15:28:45EXetoCthe purpose is just to abstract over multiple types, as well as reducing the code size (amounts of procs), by not generating separate procs for sequences and arrays
15:31:36EXetoCvarargs however might make it seem as though nothing is being allocated on the heap, but it's just an openarray in disguise

17:13:50Araqdrewsrem: c2nim can do this
17:16:15drewsremAraq, I saw the user manual and figured it out
17:16:44Araqthe user manual is not up to date with the state of the art :P
17:17:24drewsremoh... - I did the header thing by adding the ifdef c2nim macro thinges into the .h files
17:18:44Araqyeah, these days I prefer to use: c2nim config.c2nim header.h
17:19:04Araqand config.c2nim has all the #def's and #header and #cdecl and the other stuff you need
17:19:21Araqthis way translating more than 1 header is much easier
17:19:56drewsremAraq, I do this, copied it from the Urhonimo GH repo, but how'd I write that in the c2nim file?
17:20:12drewsremoh ...
17:20:17Araqsame as in the .h file
17:20:32drewsrem... right, great!

23:05:16newtonimhi to all. I found Nim while looking for a language C for development on embedded devices. right now I'm also interested in Lua and the TekUi GUI toolkit which seems just the right thing (minus Nim speed and smaller size). so my question is if anyone considered porting the Tekui code and concept (small, doesn't require a wm, few dependencies ewtc) to Nim.
23:06:04newtonim"for a higher level language than C"
23:06:38EXetoCWTF poland?
23:08:23EXetoCa WM isn't required?
23:08:36newtonimmore information on what I'm talking about here: http://tekui.neoscientists.org/
23:09:43reactormonknewtonim, c2nim on header files is your friend - it's probably not gonna be idiomatic but eh, it works.
23:09:47EXetoCyou mean, it's not dependent on a specific WM?
23:10:07newtonimues thanks
23:11:02EXetoCok so framebuffers are supported
23:11:32newtonimyes
23:11:48EXetoCit seems to have something similar to QML
23:12:07newtonimit would allow very small footprint interfaces to be written for use with nim
23:12:18reactormonknewtonim, if it has a C api, you're good ot go. If it doesn't you're gonna have a bad time.
23:12:23Araqnewtonim: looks very interesting, what's it written in?
23:12:38newtonimlua and some c i believe
23:12:39Araqreactormonk: bullshit, c2nim handles thousands of lines of C++ code nowadays
23:12:56reactormonkAraq, I'm not talking c vs. c++, I'm talking c vs. lua
23:12:59newtonimyes, lua and c
23:12:59EXetoC:>
23:13:04newtonimjust checked
23:13:10reactormonkthen you're golden
23:15:03reactormonknewtonim, hm, according to the overview, you'll have the lua VM running. And I'd say nim GC and lua GC at the same time might get... hairy?
23:15:54newtonimyes that's why a port it would be interesting
23:16:00*ozra quit (Ping timeout: 246 seconds)
23:18:39EXetoCreactormonk: the libraries usually do the allocation, so it's just a matter of wrapping the types, unless you're referring to something else
23:18:54reactormonknewtonim, ah, you want to port it.
23:19:04reactormonksorry, I though you want to use it.
23:19:07newtonimhaving a lua user interface talking with the underlying nim program could work but also defeat the purpose of having minimal footprint in case of small devices
23:19:18newtonimyes, ...well.. I'd like to be able to
23:19:33Araqwell I downloaded it and am skimming the code
23:19:49Araqso far I see clean C headers and no Lua code in the implemenation either
23:20:45EXetoCbut the wrapper would have to be allocated on the GC which imposes some overhead, since you can't achieve reference semantics otherwise (no overloading of = yet)
23:21:39AraqEXetoC: overloading of '=' works, it's just that it doesn't work with destructors yet. it's however a single bug preventing that from working
23:21:45newtonimbasically it would be a killer feature (IMO) if a nim program could create similar
23:21:47EXetoCok
23:22:19EXetoCwhat I said might not be relevant anyway, if indeed the C code does not depend on lua
23:22:26newtoniminterface without a ton of dependencies
23:23:25Araqnewtonim: have you looked at "iup" too?
23:23:26EXetoCIUP doesn't have that many dependencies, but it might be too basic
23:23:36newtonimnot yet
23:24:11newtonimI'm really new to nim, just read some articles and code
23:24:47EXetoCwe soon have a high level GTK and Qt (just QML?) wrapper, and Araq has a usable (but unfinished?) wxwidgets interface, so things are shaping up nicely
23:25:13newtonimthat's good
23:28:37*antium is now known as dtscode
23:29:01newtonimI'm probably a bit old fashioned also (grey beard, hehe) but I'd love a dead tree book on the language; I like online references but also love reading far away from the computer. Should they write one, I'm getting it as soon as they print it.
23:30:01EXetoCis it a unix beard though? if so then you are welcome here any time
23:30:56Araqnewtonim: books about Nim are in the works, but won't be ready this year
23:31:01newtonimyes, linux since 1997 and some aix and tru64 at work. but i'm by no means an expert.
23:31:30Araqhowever the manual is available as a PDF
23:31:36EXetoCyou could ask the authors of various tutorial websites if they could adapt them for printing, if they don't look good on that format already

23:34:38EXetoCdead tree books are nice; especially for fiction :-p
23:39:15newtonimgoing to bed, it's 1:40 here
