Allow command line options to called scripts about pycallgraph

Hi,

you can achieve this by the following:

change:

execfile(args[0])

to:

saveargs = sys.argv # save sys.argv
sys.argv = [args[0]] + args[2:] # store custom sys.argv
execfile(args[0])
sys.argv = saveargs # restore sys.argv in case it is needed later...

in scripts/pycallgraph-dot.py (version 0.4.1).

Then you can supply arguments to the script after stopping argument processing with '--'.

Example:
pycallgraph-dot.py which pycallgraph-dot.py /tmp/test.png -- -h

The -h option is then passed to the exec'd version of pycallgraph-dot.py.

Best,
Staal

Sorry about the formatting in the above comment. Forgot to preview...
So, the hack (it is a hack) should have looked like this:

Change lines 109-110 in pycallgraph-dot.py (version 0.4.1):

{{{
execfile(args[0])
pycallgraph.make_dot_graph(args[1], options.format, options.tool)
}}}

to

{{{
_my_saveargs = sys.argv
sys.argv = [args[0]] + args[2:]
_my_imagefile = args[1]
_my_options_format = options.format
_my_options_tool = options.tool
execfile(args[0])
sys.argv = _my_saveargs
pycallgraph.make_dot_graph(_my_imagefile, _my_options_format, _my_options_tool)
}}}

For this to work, we hope that the code in args[0] does not alter any globals that are needed by pycallgraph, in particular the globals that start with 'my'.

Best,
Staal
