| 16 | .SH SYNOPSIS |
|---|
| 17 | \fBrename \fIoldName newName\fR |
|---|
| 18 | .BE |
|---|
| 19 | |
|---|
| 20 | .SH DESCRIPTION |
|---|
| 21 | .PP |
|---|
| 22 | Rename the command that used to be called \fIoldName\fR so that it |
|---|
| 23 | is now called \fInewName\fR. |
|---|
| 24 | If \fInewName\fR is an empty string then \fIoldName\fR is deleted. |
|---|
| 25 | \fIoldName\fR and \fInewName\fR may include namespace qualifiers |
|---|
| 26 | (names of containing namespaces). |
|---|
| 27 | If a command is renamed into a different namespace, |
|---|
| 28 | future invocations of it will execute in the new namespace. |
|---|
| 29 | The \fBrename\fR command returns an empty string as result. |
|---|
| 30 | .SH EXAMPLE |
|---|
| 31 | The \fBrename\fR command can be used to wrap the standard Tcl commands |
|---|
| 32 | with your own monitoring machinery. For example, you might wish to |
|---|
| 33 | count how often the \fBsource\fR command is called: |
|---|
| 34 | .CS |
|---|
| 35 | \fBrename\fR ::source ::theRealSource |
|---|
| 36 | set sourceCount 0 |
|---|
| 37 | proc ::source args { |
|---|
| 38 | global sourceCount |
|---|
| 39 | puts "called source for the [incr sourceCount]'th time" |
|---|
| 40 | uplevel 1 ::theRealSource $args |
|---|
| 41 | } |
