Procedures to split texts

::textutil::split::splitx string ? regexp ?
The package
textutil::split provides commands that split
strings by size and arbitrary regular expressions.
The complete set of procedures is described below.
-
::textutil::split::splitn string ? len ?
-
This command splits the given string into chunks of len
characters and returns a list containing these chunks. The argument
len defaults to 1 if none is specified. A negative
length is not allowed and will cause the command to throw an
error. Providing an empty string as input is allowed, the command will
then return an empty list. If the length of the string is not an
entire multiple of the chunk length, then the last chunk in the
generated list will be shorter than len.
-
::textutil::split::splitx string ? regexp ?
-
This command splits the string and return a list. The string is
split according to the regular expression regexp instead of a
simple list of chars.
Note that if you parentheses are added into the regexp, the
parentheses part of separator will be added into the result list as
additional element. If the string is empty the result is the
empty list, like for split. If regexp is empty the
string is split at every character, like split does.
The regular expression regexp defaults to "[\\t \\r\\n]+".
This document, and the package it describes, will undoubtedly contain
bugs and other problems.

Please also report any ideas for enhancements you may have for either
package and/or documentation.
