Alex, you might have gotten me wrong. I was looking for something to display the possible choices of an option within that options help.

Example:
parser.add_option(“-m”, “–mesh”, choices=['dt_planar_trimesh','af_planar_trimesh','af_planar_quadmesh'],\
dest=”mesh”,\
help=”algorithm and element type for automeshing [%default out of %choices]“)

However, “%choices” is not translated into (‘dt_planar_trimesh’,'af_planar_trimesh’,'af_planar_quadmesh’), which would be nice…

I am currently struggling to print the choices in a %prog mnemonic way. It seems there is only “%prog” and “%default” available, but not “%choices” or the like..?

Above you show opts.__dict__[key], that could be used if I hold all the items in another list first and then iterate over that. I tried parser._get_all_options()…

opts is a simple dictionary.
You can do:
opts.new_var = <new_var_value>
it will create opts member called new_var and assign it a value new_var_value.

for i in parser.values:
print( “%s – %s” % (i[0], i[1]) )

But parser.values (which is the same as opts) is not a sequence.

One thing I could not find an answer to is how can you disable the automatic help feature? When I use:

parser.add_option(“-h”, “–help”, action=”store_true”, dest=”showHelp”, default=False)

I get an error like this:

optparse.OptionConflictError: option -h/–help: conflicting option string(s): -h, –help

I would like to implement my own usage/help message.

Thanks
