13:30:50physixerhello trying to get into nim (experienced in Python, C). I looked at C code for greetings.nim (the tutorial code) and it has greetings.c and stdlib_system.c. stdlib_system is the "supporting runtime"?
13:31:56UberLambdahow does nim know how to free resources?

13:44:13physixernim has generics, templates, and macros. Why?
13:45:54*smodo joined #nim
13:47:07softinioWhy do you ask? I think is a good thing. Sounds like you don't.
13:48:19physixerIt's essentially once concept, why offer it in three flavors?
13:48:26physixer*one concept
13:48:48*merowinger joined #nim
13:51:20r-kuphysixer each of them do different things and work best in different situations
13:52:04r-kuhaving only one would make it a half-assed solution at best because you cant be perfect doing all the things
13:52:37reactormonkphysixer, templates are basically dumbed-down macros.
13:53:47merowingerphysixer, read up here http://hookrace.net/blog/what-is-special-about-nim/
13:55:39physixermerowinger: that link is very general, doesn't even mention generics
13:55:47*joelmo quit (Quit: Connection closed for inactivity)
14:00:05coffeepotgenerics are a way to create code that works on a range of types, templates and macros are metaprogramming which is basically writing code that writes code, so they're quite different
14:01:41*MyMind joined #nim
14:03:51*Sembei quit (Ping timeout: 255 seconds)
14:04:20coffeepotfor example, i have an octree implementation that uses generics to allow you to store any type as the node, and uses templates to create a proc that lets you write procedures that traverse the tree. So, for example createTreeProc(myProcName, tpNodesOnly): <do stuff on nodes>. Then I can call myProcName(area) and it does the stuff I want. This lets
14:04:21coffeepotme write different procs that act on the tree in a couple of lines of code, and also I only need to change the tree traversal code in one place
14:08:08coffeepotmacros are another level beyond templates where you build the compiler's tree with code. I've not any experience with those yet though so can't really fill in examples of their usefulness, but the general impression I get is that macros allow you to extend the language by creating "built in" style syntactic constructs without the runtime overhead
14:09:19reactormonkcoffeepot, they're just a bit more powerful templates.
14:11:07coffeepotreactormonk, but a different way of working, isn't it - building the tree manually instead of simply substituting or producing code?
14:11:26coffeepotI once called templates "super inlining" :D
14:11:45coffeepottongue in cheek ofc

16:36:13Peter_Hi! Can I ask a quick question about shallowCopy? I might not understand some concepts here.
16:36:23reactormonkPeter_, go on...
16:36:28Peter_var x = @[1,2,3]
16:36:31Peter_var y: seq[int]
16:36:35Peter_shallowCopy(y, x)
16:36:39Peter_x[0] = 99
16:36:40*UberLambda quit (Read error: Connection reset by peer)
16:36:41reactormonkPeter_, please use a pastebin.
16:36:41Peter_echo y[0]
16:36:46Peter_That's all.
16:36:52reactormonklike gist. Or come gitter, where that's builtin
16:36:53Peter_What should be the output?
16:37:03*Ven quit (Quit: My MacBook has gone to sleep. ZZZzzz…)
16:41:26Peter_On pastebin: http://pastebin.com/G8U2jfAG
16:47:22Peter_I thought that shallowCopy works the same as y=x in python, so ``echo y[0]`` should result 99.

22:57:14Araqaw1231: are you on windows?
22:57:42aw1231yes
22:57:55Araqthen you already have nimble.
22:58:08aw1231where is it located then?
22:58:10Araqthe installer ships with it
22:58:22aw1231I'm building from source.
22:58:29Araqah ok
22:58:44Araqok, so what's the error message?
22:59:26aw1231(1, 21) Error: undeclared identifier: 'install_nimble'

23:02:53Araqworks for me

23:42:15tmm1Araq: where would i add buitin for gcc version?
23:42:24tmm1i couldn't find where gcc clang etc were declared
23:43:00Araqyou need to improve your (nim)grep-foo then
23:43:05Araqit's in extccomp.nim
23:44:02Araqand yes, if you wonder. that filename predates the invention of long filenames.
23:45:36*strcmp1 quit (Remote host closed the connection)
23:45:58Araqtmm1: that's where 'clang' etc are defined, but that has nothing to do with adding new builtins
23:46:17Araqfor that you could write a compiler plugin
23:48:13Araqtmm1: however, do we need to support older GCCs which don't know about C++'s threading primitives?
23:51:53*vendethiel quit (Ping timeout: 265 seconds)
23:56:54tmm1Araq: i just want the tests to pass on travis
23:57:14tmm1its using ubuntu precise which is not that old, i think nim should not try to use the atomic symbols if they're not available
23:57:19tmm1instead of producing a broken binary
23:57:39Araqwell it should affect the threading tests
23:57:52Araqwhich is not in our list of essential tests
23:58:01Araqwhat am I missing?
23:58:39tmm1it would be nice to run all the tests
23:58:48tmm1we can split it into multiple travis jobs so they run in parallel
23:59:23tmm1what's the status of compile-time ffi? would be nice to be able a macro like GNU_MAJOR at compile time more easily since that's common when dealing with c code
