# textutil\_split(3tcl)

Procedures to split texts

```

```

## NAME

textutil::split - Procedures to split texts

## SYNOPSIS

package require **Tcl 8.5 9**

package require **textutil::split ?0.9?**

**::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*: 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 "\[\\\\t \\\\r\\\\n\]+".

## 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 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.
