[TCLCORE] Re: [trace execute] for [onexit callback]

[Vince D. <vin...@my...>]

I had some spare time over the weekend, so I implemented 4 new options to 'trace add/remove command', in addition to the rename/delete options which are already in Tcl 8.4a2.

These new options are: before, after, preinside and postinside (the names for the last 2 are horrible, I agree!).

A patch is available at:

ftp://ftp.ucsd.edu/pub/alpha/tcl/tracecmdexec.diff.gz

Which should apply cleanly to the latest cvs pull.

There is no documentation or tests for the new code.  However all old tests pass, except for 6 in trace.test which fail because an error message has changed.

Here is an example:

administrator@TRAPPER //c/tclsource/tcl8.4cvs/win/Release
$ tclsh84
% proc onexit {script} { trace add command exit before "$script ; #" }
% onexit "puts hi"
% exit
hi

administrator@TRAPPER //c/tclsource/tcl8.4cvs/win/Release
$

The patch is reasonably complete: I've checked that stuff like deleting a trace or deleting a command while traces/commands are executing works ok.

Comments appreciated,

Vince.
