This module defines a number of functions useful for working with
regular expressions (see built-in module \code{regex}).
Warning: these functions are not thread-safe.

\begin{funcdesc}{split}{str\, pat}
\begin{funcdesc}{split}{str\, pat\optional{\, retain}}
Split the string \var{str} in fields separated by delimiters matching
the pattern \var{pat}, and return a list containing the fields. Only
non-empty matches for the pattern are considered, so e.g.
\code{split('a:b', ':*')} returns \code{['a', 'b']} and
\code{split('abc', '')} returns \code{['abc']}.
If the optional \var{retain} argument is true, the separators are also
inserted in the list, so e.g. \code{split('a:::b', ':*', 1)} returns
\code{['a', ':::', 'b']}.
