to use regexes the option --enable-unicode-properties must be provided about hello_musl HOT 5 CLOSED

This is a markdown package issue as far as I can tell, sorry to bother you, the config is extensible enough to work it around if you understand well your dependencies, thanks again for your work.

Normal regex works without that switch. Are you trying to enable support of unicode characters?

Also, can you provide a minimal example that fails if pcre is not compiled with that switch?

Thanks.

Hi again, look, my error is exactly the one the OP mentions in: crystal-lang/crystal#2662,
I'm using import regex and I'm using the following regexes to get the plain name of a file without path or extension

const b1 = re"/(.*)\.[^.]+$"
const b2 = re"\.tales/(.*)"

proc ListTales(): seq[string] =
  for file in walkFiles("./tales/*"):
    result.add file.replace(b1, "$1").replace(b2, "$1")

This might not be the best way to achieve this but it works, it seems that also the package markdown that uses regular expressions extensively fails if we don't compile pcre with said flag,

  if title in ListTales():
    readFile("./tales/" & title & ".md")
      .markdown

at least the use of markdown library should fail, I really couldn't test the other part, setting the flag in the config file solved
it.

when not defined(usePcreHeader):
  when hostOS == "windows":
    when defined(nimOldDlls):
      const pcreDll = "pcre.dll"
    elif defined(cpu64):
      const pcreDll = "pcre64.dll"
    else:
      const pcreDll = "pcre32.dll"
  elif hostOS == "macosx":
    const pcreDll = "libpcre(.3|.1|).dylib"
  else:
    const pcreDll = "libpcre.so(.3|.1|)"
  {.push dynlib: pcreDll.}
else:
  {.push header: "<pcre.h>".}

Upon closer inspection I think it might be due to the markdown package, this is found in the package that uses pcre.
