Regular expressions are enclosed in matching pound sign (#) characters with a prepended re: re#...#. KRL regular expressions follow the JavaScript standard, which closely follows the conventions for Perl regular expressions. The following modifiers may appear after the closing character:
i. The i modifier makes the regular expression case insensitive.g. The g modifier applies the regular expression globally.
For example, the following code replaces the first instance of foo in p with bar:
p.replace(re#foo#, "bar")
In contrast, the following code replaces all instances of foo in p with bar:
p.replace(re#foo#g, "bar")
