NAME

textutil::split - Procedures to split texts

SYNOPSIS

package require Tcl 8.2 package require textutil::split ?0.8? ::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. Pro‐ viding 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: When paren‐ theses are used in the regexp, i.e. regex capture groups, then these groups will be added into the result list as additional elements. 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 prob‐ lems. Please report such in the category textutil of the Tcllib Trackers [http://core.tcl.tk/tcllib/reportlist]. Please also report any ideas for enhancements you may have for either package and/or documentation. When proposing code changes, please provide unified diffs, i.e the output of diff -u. Note further that attachments are strongly preferred over inlined patches. Attachments can be made by going to the Edit form of the ticket immediately after its creation, and then using the left-most button in the secondary navigation bar.
