03:17:16ftsf_hmm http://stackoverflow.com/questions/30037165/where-does-nim-search-for-modules-to-import is this accurate? specifically "Relative to the directory of the main module (again, via import dir.modname or import dir/modname if it's not in the same directory)."
03:18:33ftsf_i have a src/main.nim which imports modules.foo src/modules/foo.nim imports common (src/common.nim) but this fails Error: cannot open 'common', when compiling with nim c src/main.nim
03:33:12ftsf_hmm different modules with the same name but in different directories all seem to go into the one dir in nimcache with their directory removed
03:33:44ftsf_eg. i have import modules/foo and import foo they both seem to become nimcache/foo.{c,o} =\

16:38:23Varriount|MobileYou can also look at the generated C code.

22:05:24dyce[m]excuse my very weak understanding of types (i simply know the difference between dynamic and static), could someone tell me how nim is has a better type system than lets say java?
22:08:03vlad1777ddyce[m], why do you decided that it's better? I think that types in every static language are very similar, so I cannot tell, which one is better.
22:09:05*yglukhov quit (Ping timeout: 246 seconds)
22:10:36dyce[m]vlad1777d like for example, haskell's type system is very strong, up to the point where its doesnt need unit testing. like you can define that a some variable should be a list that is never empty rather than checking if the list is empty in your code.
22:10:56dyce[m]my understanding is that Nim too also have a pretty strong type system
22:11:36vlad1777ddyce[m], you can write such types even in Python (in __init__ method)
22:12:21vlad1777ddyce[m], but I'm newbie in Nim, so I cannot tell you about it's system. I read manuals, seems that it's system is general.
22:18:20*Varriount|Phone joined #nim
22:19:10Varriount|Phonevlad1777d: Nim's type system is lower-level than java or c#
22:19:44Varriount|PhoneHowever it's fairly flexible, being Beyer than Java at least
22:19:57Varriount|Phone(No type erasure!)
22:20:28Varriount|Phone*better
22:20:48Varriount|PhoneStill needs variadic generics though.
22:22:29vlad1777ddyce[m], above is ansver on your question
22:24:28Varriount|Phonedyce[m]: Basically, Nim has the standard static type system, with low level additions and good generic support
22:25:01Varriount|PhoneThere's also Concepts, which are akin to a restricted generic type
