Re: Matching a keyword, value and optional comma delimited values

[BooK]

You can try those:

• if you have not more than 3 optional values:

  # match everything at once
  @everything = /^\s*(\w+)\s*=\s*(\w+)(\s*,\s*\w+)?(\s*,\s*\w+)?(\s*,\s*
  +\w+)?$/
  

• if you can have any number of optional values, you have to use \G (explained in perlop and perlre)

  # match the required part
  /^\s*(\w+)\s*=\s*(\w+)/gc;
  ($keyword, $value) = ($1,$2);
  # match the optional part
  @optional = /\G\s*,\s*(\w+)/g;
