NAME

rename - Rename or delete a command

SYNOPSIS

rename oldName newName _________________________________________________________________________________________________

DESCRIPTION

Rename the command that used to be called oldName so that it is now called newName. If newName is an empty string then oldName is deleted. oldName and newName may include namespace qualifiers (names of containing namespaces). If a command is renamed into a different namespace, future invocations of it will execute in the new namespace. The rename command returns an empty string as result.

EXAMPLE

The rename command can be used to wrap the standard Tcl commands with your own monitoring machinery. For example, you might wish to count how often the source command is called: rename ::source ::theRealSource set sourceCount 0 proc ::source args { global sourceCount puts "called source for the [incr sourceCount]'th time" uplevel 1 ::theRealSource $args }
