in thread regex needed

It may help to talk it through in words first. The pattern you're looking at is:

  • Two dollar signs (metacharacters, will need escaping)
  • An open parenthesis (also needs escaping)
  • Some text up to a closed parenthesis (capture this in $1)
  • A closed parenthesis (escaped)
  • Anything else that exists beyond that (captured in $2)

Now just put those elements together in a regex:

if( $line =~ m[ \$\$ # two dollar signs \( # open paren ([^)]+) # capture until closed paren \) # close paren (.*) # capture the rest, if any ]x ){ # do stuff with $1 and $2 }
