  Hi. Does Nim supports resources embedding? I can't find any information about it.

  You can read a file at compile time an store it as a const string

  
  proc staticRead(filename: string): string
  Run

  see documentation

  Thanks! But it will work only for text, what about binary files?

  Not an expert, but afaik string is just a sequence of chars and char is always a byte. Thus you just staticRead and then may access each byte using subscript []. Haven't heard about other ways of dancing with bytes in nim :/

  For Windows, you can try to compile your resources with some resource-compiler (to .res files), and link to your program via {.link: ... .} pragma. Look at koch.nim or nim.nim for examples.

  Nim opens files always in binary mode. Standard library functions like e.g. splitLines cope with all kinds of line endings, you don't have to worry about that.

  So basically you can use strings just as binary blobs but it's recommended to use seq[byte] for them instead(https://forum.nim-lang.org/t/3173#20096). You can convert strings to seq[byte] by using cast[seq[byte]](myString). I don't know if this behavior is guaranteed somewhere, I just picked it up from Nim code by others(it probably won't work when compiling to JS or when using Nimscript).
