6341 :: Conflict of nfatype.Regex and nre.Regex

• svtz (orginal) [2020-05-15T20:23:31+02:00] view original

  Let's imagine a code starting like this.

  
  import os, times, glob, strutils
  from nre import replace, Regex
  
  proc decipher(file: string): string =
      let pathsplit = splitPath(file)
      let tail = pathsplit.tail.replace(Regex("^[\!\+\-]+\s"), "")
      let head = pathsplit.head
      ....
  Run

  In VS Code, I get the following message:

  
  expression 'Regex' cannot be called
  attempting to call routine: 'Regex'
  
  found 'nfatype.Regex [declared in /home/svtz/.nimble/pkgs/regex-0.15.0/regex/nfatype.nim(46, 3)]' of kind 'type'
  found 'nre.Regex [declared in /home/svtz/.choosenim/toolchains/nim-1.2.0/lib/impure/nre.nim(69, 3)]' of kind 'type'
  Run

  How does one usually deal with such conflicts? Or is there something wrong with my Nim installation?

  one option is to write nre.Regex or nfatype.Regex

  glob anyways imports the regex module ( https://github.com/nitely/nim-regex ). So you might as well just use that instead of importing nre.

  nre will introduce a dependency on PCRE on your app, while the nim-regex module won't.

  Thank you both! Indeed, I simply wrote

   = pathsplit.tail.replace(re"^[\!\+\-]+\s", "")
  Run

  without importing any regexp library explicitly, and it works fine.
