13:47:17renesacon a related note
13:48:19renesacif we moved only | below & or & above | in the precedence table, we could fix the issue with bitwise operation precedence regarding comparison operators

13:50:38renesacxor would become an ugly |^, but at least it would be clear, to those who know the rules, that it is the same precedence than |
13:50:43renesac(or)
13:56:23renesacor better, I will open an issue for it
14:02:13Araqrenesac: how so?
14:02:27Araqwhat has | and & to do with anything?
14:02:51renesacif we used them for bitwise operations
14:04:38*milosn quit (Read error: Connection reset by peer)
14:04:43renesacI'm writting a issue on github explaining better
14:04:59*milosn joined #nim
14:05:12*Sembei joined #nim
14:05:53Araqwell you won't like that, but I think |< |> |& || |^ is kind of cute, | then means "bitwise"
14:06:16renesac|| is already used for parallel
14:06:41Araqonly as an iterator though, so there is no clash
14:06:50Araqwell not an important clash anyway
14:07:10renesacand it would be nice if at least & is at an higher priority than the rest
14:07:15renesacbut I do agree that it is cute
14:07:24*Sembei quit (Max SendQ exceeded)
14:07:34renesac|^ won't look as ugly then
14:07:47Araqwhy does & need a higher prio?
14:08:05renesacalmost all languages give it higher priority
14:08:09renesacincluding nim
14:08:30Araqbut in Nim it's not bitwise AND
14:08:56renesacbut of course we can adopt the smalltalk way regarding that and parenthesis can be used in complex operations
14:09:25*Sembei joined #nim
14:10:14renesacwell, it is bitwise AND, at least for now
14:11:14Araqfor whom? for Nim it's concat in general
14:11:41renesacoh, I'm talking about the current relative priority of AND and OR
14:11:44renesacfor bitwise
14:11:58renesacand that most languages adopt that
14:12:17renesacsometimes with XOR in an intermediate priority, sometimes in the same priority as OR

20:14:55pigmejac have quite nice features which are non existent in company but... ;-)
20:15:11pigmejI will try to do company backend which uses nimsuggest
20:15:14reactormonkpreferably you'd split the backend vs. the frontend
20:15:19pigmejsure
20:15:51pigmejsimilar like anaconda does for python
20:15:53reactormonkhow exactly do you invoke nimsuggest? I've messed with nim serve before
20:16:08pigmejnimsuggest is client - server
20:16:23pigmejso preferably / probably emacs will open one nimsuggest for project
20:16:33reactormonkyup
20:16:38pigmejor maybe one global if it can handle different files
20:16:43pigmej(haven't checked yet)
20:16:52pigmejthen elisp will talk to nimsuggest directly
20:17:09reactormonkkinda. you make a buffer where you store the communication in
20:17:16pigmejnimsuggest can communicate over stdin
20:17:20reactormonkexactly.
20:17:25reactormonkelisp works via buffers.
20:17:32pigmejyeah
20:17:36pigmejsome hidden some not
20:18:06reactormonkpreferably nimsuggest would talk in sexp ;-)

20:21:28reactormonkI don't see any code reference to jedi

20:22:25reactormonkanaconda looks good to me, your pick
20:22:36Jehan_Is there a way to either (1) efficiently set all elements in a set of type set[1..100] or (2) create the complement of such a set?
20:22:41pigmejyeah I use anaconda every day :)
20:22:51reactormonkgo for that one then
20:23:09pigmejhttps://github.com/proofit404/anaconda-mode/blob/master/anaconda_mode.py maybe that would be the easiest way :)
20:23:12reactormonkJehan_, write a literal?
20:23:19AraqJehan_: {1..100} ?
20:23:25Jehan_The problem is that when I use {1..100}, it's interpreted as a set[0..65535] and I don't seem to be able to cast it down to set[1..100].
20:23:34reactormonkpigmej, yeah, but no python dependencies
20:23:45Araqtype R = range[1..100]
20:23:53Araq{1.R .. 100.R} ?
20:24:11Jehan_Hmm, this didn't work, either, but I may have screwed it up, let me try again.
20:24:31Araqmaybe there is a bug in the compiler.
20:24:42*pafmaf joined #nim
20:25:54Jehan_Ah, nevermind, got it. I forgot the range[] around the actual range.
20:28:18Jehan_Still not pretty, but it works.

22:13:11Araq"Changes affecting backwards compatibility"
22:13:11BlaXpiritbut seriously, how many pull requests will it take until `re` is good?

22:14:07BlaXpirituh sorry, that's not what i meant
22:14:13a5io
22:14:20BlaXpiritanyhow, to try this thing out, you should go to #nim-offtopic
22:15:08reactormonkAraq, into "Changes affecting backwards compatibility" that's under "2015-03-01 Version 0.10.4 released"? Feels kinda wrong to me
22:15:24Araqno no no, ugh
22:15:35Araqthere was no release of 0.10.4
22:15:54Araqthat date was just my wishful thinking
22:15:59reactormonkhttps://github.com/Araq/Nim/blob/devel/web/news.txt#L6
22:16:11BlaXpiritAraq, why is `nre` not in standard library?
22:16:40AraqBlaXpirit: because we like to trim the stdlib, not bloat it
22:16:51a5iglad to see the Rust vs Nim clash from some trolls on both sides done for
22:16:54BlaXpirityou see, the problem we have is
22:17:07EXetoCa5i: echo is part of the code there. it's not an eval argument or anything, so use echo if you want to print something
22:17:07BlaXpiritthe main criteria for stdlib is who got in there first
22:17:12BlaXpiritthat's not wise
22:17:20a5iohhh

22:20:17AraqBlaXpirit: should we wait until we have 3 implementations until we decide?
22:20:43BlaXpiritwe now have 1 good implementation
22:22:06*egrep quit (Ping timeout: 272 seconds)
22:22:37Araqwe also have lots of projects which already use 're'
22:22:48Araqand nre is not compatible
22:23:37Araqit's not too much effort to fix re, it's just that people have better things to do
22:24:00BlaXpiriti'm being too obnoxious for sure
22:24:13BlaXpirityou're making some good points
22:24:40BlaXpiritthe problem i have is people don't know about nre
22:25:25flaviuAnother option might be to move almost everything out of the stdlib, and allow third parties to make decisions of merit.
22:25:28BlaXpiritif you don't want to include a lib but we know it's better, why not tell people about it
22:28:49AraqBlaXpirit: we have many people still using 0.10.2 and report bugs about it. that's the problem no 1 right now, we need to get 0.10.4 out.
22:28:52federico3hm, koch web is failing to build in devel due to ../doc/exception_hierarchy_fragment.txt
22:29:06BlaXpiritAraq, that's a big problem, another one that i mentioned
22:29:13BlaXpiritbut different than what we were just talking about
22:29:25BlaXpiritfederico3, that's an old one
22:29:55federico3BlaXpirit: an old file? an old version of koch?
22:30:07BlaXpiritan old version of nim had this fault
22:30:12BlaXpiritold, as in latest released version
22:30:14BlaXpirit(speak of the devil)
22:31:19AraqBlaXpirit: he said he is using devel
22:31:43BlaXpiritthat can't be right. could it be an old devel?
22:32:34federico3hm, let me see, ./bin/nim | grep Ver is 0.10.3 (branched today)
22:33:48federico3I'm rebuilding koch making sure it's built with that version, than doing koch boot and koch web
22:35:41federico3same; could it be that koch or nim are picking up stuff from a system-wide installed version?
22:36:27BlaXpirityes
22:36:29BlaXpiritfederico3, yes, it does
22:36:41BlaXpiritthat's exactly the problem, if you don't have devel nim in path
22:36:58BlaXpiriti discovered this just now, should've thought
22:37:49federico3aha
22:38:08federico3and if I set PATH='.' it won't find gcc then :-/
22:38:23*vendethiel quit (Ping timeout: 250 seconds)
22:38:28BlaXpiritwell don't replace your PATH
22:38:30BlaXpiritadd to it
22:39:13BlaXpiritPATH=".:$PATH" ./koch web
22:39:36federico3I'd rather isolate it completely from the system path
22:40:08BlaXpirittough luck
22:40:21BlaXpiritwell of course you could investigate and fix this
22:40:33AraqI think you can call nim /path/to/it/nim too and then things work as long as everything is in /path/to/it
22:40:54Araqwhich shouldn't be /usr/bin then of course
22:41:05Araq /opt comes to mind
22:42:54Mat4or you can simply use a more recent CLI which automatical include the current directory to the search path
22:43:04BlaXpiriti can't seem to emit in nim js?
22:43:06federico3it's building (and taking quite some time)
22:43:07Mat4something other than Bash
22:43:37BlaXpiritMat4, that's nonstandard. you can't present it as an advantage.
22:43:58BlaXpiritby "something other than Bash" you probably mean "that one obscure shell i use"
22:43:58*Joe-T quit (Quit: ZNC - http://znc.in)
22:45:57federico3PATH=".:./bin" ./koch web does the trick, after symlinking gcc and ld locally
22:46:30AraqBlaXpirit: you can use .emit
22:46:32Mat4this feature was only a script away even in the original C shell way back to ... the 70's
22:47:20fowlfederico3, i usually symlink nim into $PATH

23:01:20dhasenanSo, I have in C++: template<typename T, typename U> class Map { struct Iterator {}; };
23:01:24dhasenanHow do I wrap that in Nim?
23:01:34dhasenanI should probably ask this on stackoverflow, actually...
23:02:58fowldhasenan, you want an generic type that holds no data? ;P
23:03:20dhasenanfowl: I don't want to paste 500 lines of code into IRC.

23:05:37Araqoh yeah
23:05:41BlaXpirityes, Araq
23:05:43AraqI confused .emit with asm
23:05:55BlaXpiritwell apparently i confused them too
