7435 :: How do I list the files in a directory in Nim?

  I don't see a proc that would do this in the os library. I do see listFiles in the nimscript library though, however, my code needs to be run at runtime, so nimscript isn't an option.

  let filesInPath = toSeq(walkDir("path", relative=true))

  Run

  The easiest way I can think of would be to do the following.

  import os, sugar
  let files = collect(newSeq):
    for file in walkFiles("*"):
       file
  Run

  imho the most idiomatic way of doing this is:

  import os
  var paths: seq[string] = @[]
  for path in walkFiles("*"):
    paths.add path
  Run

  This is not C or Go, no need to be afraid of abstraction.

  If we're going to do it without sugar atleast make it the same result with an immutable list of files.

  import os
  let files = block:
    var res: seq[string]
    for f in walkFiles("*"): res.add(f)
  Run

  Don't deny yourself sugar, you are worthy, you deserve it

  I understand that useing sugar makes the code sweet, but I think for beginners it is essential to know what is going on, sugar can be applied later when you know what you're doing.

  I would say it's important for beginners to see sugar version, as otherwise a person may see verbose non-sugar version and never look at Nim again.

  if only the file name is required:

  
  proc all_files*(path:string):seq[string] = toSeq(walkDir(path)).mapIt(it.path)
  Run
