NAME

       textutil::split - Procedures to split texts

SYNOPSIS

       package require Tcl  8.2

       package require textutil::split	?0.7?

       ::textutil::split::splitn string ?len?

       ::textutil::split::splitx string ?regexp?

_________________________________________________________________

DESCRIPTION

       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]+".

BUGS, IDEAS, FEEDBACK
       This document, and the package it describes, will undoubtedly contain bugs and other problems.  Please report such in the category textutil
       of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883].  Please also report any ideas for enhancements you may have for
       either package and/or documentation.
