Summary: new improved trace.py
Initial Comment:
trace.py didn't work for me with Python 2.2a4+,
possibly due to me misunderstanding how to use it.
In any case this version is substantially rewritten,
uses the debugger hooks that were introduced in Python
2.1(?), and has a simpler (in my opinion) interface.
Also there are some new features like "countfuncs" mode
which is faster than "count" mode and reports only a
list of funcs that were invoked.

Uh... Oh yeah, you're right. (I actually use it
programmatically and not through the command line.)
Okay I don't know *what* it is supposed to do. I'm working
on figuring it out right now and I'll submit a patch when done.

Well, then it doesn't work. When I do "trace.py --count
hello.py", it doesn't print any usage stats to stdout. When
I add "--file foo", it writes some binary data to foo. When
I then do "trace.py --report --file foo hello.py" I get no
output. This is with your version, but Skips version had
the same problem.

Guido: did you see the usage string?
I'm looking at it and not seeing how to make it more clear
right now. Okay I'll try tweaking it a bit...
In Mojo NatioExecution:
--help Display this help then exit.
--version Output version information then exit.
-t,--trace Print each line to sys.stdout before
it is executed.
-c,--count Count the number of times each line
is executed.
After the program exits, results
are written to the
results file if `--file' is given,
else to sys.stdout.
-r,--report Generate a report from a results
file; do not
execute any code. `--file' must
specify the results
file to read.
(One of `-t', `-c' or `-r' must be specified)
-s,--summary Generate a brief summary for each
file. (Can only
be used with -c or -r.)
I/O:
-f,--file= File name for accumulating results
over several runs.
(No file name means do not archive
results)
-d,--logdir= Directory to use when writing
annotated log files.
Log files are the module __name__
with `.` replaced
by os.sep and with '.pyl' added.
-m,--missing Annotate all executable lines which
were not executed
with a '>>>>>> '.
-R,--no-report Do not generate the annotated
reports. Useful if
you want to accumulate several over
tests.
-C,--coverdir= Generate .cover files in this directory
Selection: Do not trace or log lines from ...
--ignore-module=[string] modules with the given
__name__, and submodules
of that module
--ignore-dir=[string] files in the stated directory
(multiple
directories can be joined by
os.pathsep)
The selection options can be listed multiple times to
ignore different
modules.
n CVS:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/mojonation/evil/common/trace.py?rev=HEAD&content-type=text/vnd.viewcvs-markup
the usage string now looks like this:

I'm going to be in Europe on business for the next two weeks. I should have a fair amount of dead time in my hotel room. I'll try to take a look at it then.

I'll be happy to add doco about --count, --report, and
--file after I return from the O'Reilly p2p conference.
(i.e. more than a week from now).
Regards,
Zooko

Skip, what do you think of this?
In addition, I think there needs to e a doc string
explaining what the --count and --report options do, and how
the --file option figures.
I am completely unable to understand how these interoperate.
:-(
