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 contain-
ing 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
}
