7756 :: handle "-" and variations as valid input

• xioren (orginal) [2021-04-07T00:36:17+02:00] view original

  Is there a way to handle

  -
  Run

  and

  -words
  Run

  as a cmdArgument instead of cmdShortOption or cmdLongOption when using the parseopt module?

  what does program -shortopt --longopt cmdarg1 -cmdarg2 give?

  we could define -- as a separator if needed (grep uses -e for that IIRC)

  So that was maybe an abstract example. My real world example is I have a program that renames files by swapping "this" arguments with "that" arguments.

   [args] this[ that]
  Run

  So a scenario where the user want to swap dashes "-" with underlines "_" in filenames recursively might run the program like:

  
  replace -r - _
  Run

  However the "-" is picked up as an option not an argument by the arg parser.

  I wrote a bare bones arg parser as a work around.
