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

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;
