Re: unable to build PDF documentation

I encountered this issue while attempting to build the Arch Linux AUR nim-git package. I think the issue had to do with not being in the right directory.

Re: unable to build PDF documentation

I'm pretty sure the issue is that _nimweb_ is installed in nim/tools/ but web/website.ini is in /nim/web/website.ini and _nimweb_ is searching for _website.ini_ in /nim/tools/web/website.ini. There is probably a better way to explain that, you'll probably have to read it twice.

ok, since I wrote this, I think the example with the codec developer is just a bad example. Just because there is a codec in the standard library, doesn't main you can't develop a better one in that language. But I don't change my opinion. I think the Nim language is powerfull enough, that it

No way to run my code, idk how to force a float as an Int

hi guys I have this few line, nombreDePyramides = 4 var maxLignes: int = ((nombreDePyramides+2)*(nombreDePyramides+3)/2-4) here the second line is giving me a float but I need a int because of the rest of the code and I can't find the syntax ...

Re: No way to run my code, idk how to force a float as an Int

This happens because `/` on ints returns a float. You want to use `div` instead, which is integer division. var maxLignes = ((nombreDePyramides + 2) * (nombreDePyramides + 3)) div 2 - 4 Or, alternatively, convert it – this is clearly the inferior solution, but given here for

NimMain don't need to be called, because all GC initialization procedures can reside in DllMain() function, so there no reason to export NimMain.

Re: Audio/Video File Read/Write Support In NIM

As @krux02 mentioned, core language should be compact and flexible without diminishing its usability. Nim syntax already flexible enough so you shouldn't have any problem implementing the dsl for multimedia applications. While developing language to fill the niche is nice, it would be more nice

Re: Exploring namespaces support in Nim

@Krux02: I may be the only one to think this, but "openFile" seems just as good (from a syntax perspective) as "File.open" while the second form is far more flexible, offers more guarantees and is more easily discoverable and fixable should a problem occur... As far as I am concerned, I don't

Re: Exploring namespaces support in Nim

D supports local imports and has to deal with overloading. Nim supports the following: from foo import nil block: # Start of scope template someSymbolFromFoo(a: int): int = foo.someSymbolFromFoo(a) type SomeTypeFromFoo = foo.SomeTypeFromFoo # Use

Local imports is something I would also vote for. I bet they should be easy to implement. @Araq, what do you think?

Re: Exploring namespaces support in Nim

**yglukhov:** _I bet they should be easy to implement._ Well, first there's also the problem of semantics. OCaml, SML, and Python as three languages that support them don't have to worry about overloading. Definitions shadow each other, so that the innermost import always wins. With

Re: Exploring namespaces support in Nim

@Jehan: I see, I did not understand correctly but it is clear now. Its akin to scoped imports then and it seems far better for scientific computing (especially for operators).

Re: Exploring namespaces support in Nim

Hi! (please bear with the length, I promise this is my last long post) * * * @Araq, I quite agree with @Jehan's view that eventually, a reasonable developer would try to provide structural guarantees in his code and in that sense, your suggestion (which make sense in general) would seem weird

Yes, if the strings used are stored somewhere as `string` at the time they are checked, the output is normal, e.g.: var s: seq[string] proc genArray(i, j: int) : seq[cstring] = result = newSeqOfCap[cstring](j - i + 1) s = newSeqOfCap[string](j - i + 1) for k in
