What is optparse_gui?

optparse_gui is a python module which can be described simply by: import optparse_gui as optparse

optparse_gui is a drop-in replacement for optparse. It allows entering command line arguments in a dynamically generated wx-based dialog.

optparse is a great built-in python module for parsing command line arguments. see http://docs.python.org/lib/module-optparse.html for more info.

Features

	*optparse_gui* generates the dialog depending on the provided optparse options: CheckBox for boolean options, ComboBox for "choice" options, TextCtrl for all other options. An extra TextCtrl for entering non-option command line arguments. Also, the dialog contains context-sensitive help for every option.

Ever wanted to transparently add a GUI to your command-line driven python scripts? This is the module for you.

How to use it?

Like the title says - simply "import optparse_gui as optparse"

A more elaborate use case might be to use optparse_gui when the application is ran with no command line arguments ( i.e. a double-click on the module's icon ), but use the original optparse to handle the command line arguments if they are given.

That way, a user can drive your app using a GUI, and yet - the app can be automated by passing command line arguments.

Here is a sample( this is what you see in the screen-shot above ):

import sys
import optparse
import optparse_gui

def main():
    usage = "usage: %prog [options] args"
    if 1 == len( sys.argv ):
        option_parser_class = optparse_gui.OptionParser
    else:
        option_parser_class = optparse.OptionParser
        
    parser = option_parser_class( usage = usage, version='0.1' )
    parser.add_option("-f", "--file", dest="filename", default = r'c:\sample.txt',
                      help="read data from FILENAME")
    parser.add_option("-a", "--action", dest="action",
                      choices = ['delete', 'copy', 'move'],
                      help="Which action do you wish to take?!")
    parser.add_option("-n", "--number", dest="number", default = 23,
                      type = 'int',
                      help="Just a number")
    parser.add_option("-v", "--verbose",
                      action="store_true", dest="verbose",
                      help = 'To be or not to be? ( verbose )')
    
    options, args = parser.parse_args()

    print 'args: %s' % args
    print 'options: %s' % options

if '__main__' == __name__:
    main()
