::textutil::split::splitn string ?len?
::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: When parentheses 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]+".
This document, and the package it describes, will undoubtedly
contain bugs and other problems. 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.
