NAME
textutil::repeat - Procedures to repeat strings. SYNOPSIS
package require Tcl 8.2 package require textutil::repeat ?0.7? ::textutil::repeat::strRepeat text num ::textutil::repeat::blank num _________________________________________________________________ DESCRIPTION
The package textutil::repeat provides commands to generate long strings by repeating a shorter string many times. The complete set of procedures is described below. ::textutil::repeat::strRepeat text num This command returns a string containing the text repeated num times. The repetitions are joined without characters between them. A value of num <= 0 causes the command to return an empty string. Note: If the Tcl core the package is loaded in provides the command string repeat then this command will be implemented in its terms, for maximum possible speed. Otherwise a fast implementation in Tcl will be used. ::textutil::repeat::blank num A convenience command. Returns a string of num spaces. 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. SEE ALSO
