Hey zee3b, I figured I'd respond to your PM here so I'd have more room.
Hey, thanks a lot for the help. That really worked and was exactly what I was looking for. When you get a few mins, can you please explain how the code works for my understanding. Thanks!
# Read through file/data one line at a time. while (<DATA>) { # Remove newline from end of line (actually not necessary for your + input). chomp; # If a line ends with '{', use a regular expression (REGEX) to cap +ture # the relevant portion by having that portion surrounded by parent +heses. # Push the captured string (contained within the variable '$1', si +nce it # is the first captured string) onto the end of the array '@curren +t command'. # This REGEX matches: # the beginning of the line: ^ # 0 or more spaces: \s* # 1 or more of anything (captured because it is in parentheses +): (.+) # 1 space followed by 1 {: \s{ # the end of the line: $ push @current_command, $1 if /^\s*(.+)\s{$/; # If a line ends with ';', use a REGEX to capture the relevant por +tion, # then print out the contents of the array followed by the string +you # just captured and assigned to '$last_term'. if (/^\s*(.+);$/) { my $last_term = $1; say "set @current_command $last_term"; } # If a line ends with '}', that means we are moving up a level, so + you # remove the last element of the array '@current_command'. pop @current_command if /}$/; }
