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 charac‐
ters 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]+".
