Say you got some variables stored in a hash: name=>value and whant to replace them in a text where they are used in a make-like form: $(VARIABLE)
foreach (keys %global_variables) { $content =~ s/\$\($_\)/$global_variables{$_}/g; }
- When you want to indent a part of text and calculated the indent already you might use:
$content =~ s/\n/\n$indent /g;
- Some really often used substitutions are the whitespace deletions: 1. All whitespaces: $line =~ s/\s+//g; 2. Only leading whitespaces: $line =~ s/^\s*//; 3. Only trailing whitespaces: $line =~ s/\s*$//;
- Say you got a GUI (in my case it was Gtk) and want to display some messages. In the preview window though only the first line shall be displayed, marking that more is available:
$text =~ s/\n.*/ [more\.\.\.]/s;
Update: Added the missing parens around VARIABLE
