6984 :: listFiles() at compile time?

• ggibson (orginal) [2020-10-25T15:35:50+01:00] view original

  Just confirming, there's no way to listFiles or walkFiles at compile time, correct? This is because importc cannot be used at compile time, rendering walkFiles and execProcess unhelpful.

  My only workaround is to make a nimscript file with a build action that uses listFiles and passes this string to the compiler as a define.

  It should work with latest Nim version. Otherwise post full repro code.

  Really? That would be fantastic!

  I'm using 1.5.1 but am still having the original issue. Maybe you can see I'm doing something stupid?

  walkDir does work at compile time. Replace walkFiles/listFiles with walkDir and filter *.txt files using strutils' endsWith.

  Worst comes to worst, you could do gorge("ls ."), but as @slonik_az said walkDir (not walkDirs, but walkDirRec should also work) has a special compile time binding.

  Wow, yeah that's not documented at all! But that's exactly what I'm looking for - I would have not figured that out possibly for a long time if either of you hadn't pointed it out. Thanks a lot.

  walkDir in the static block:

  Error: cannot 'importc' variable at compile time; getcwd
  Run
