argparseui 0.0.4

Purpose of argparseui

argparseui can be used to quickly auto-generate a UI from an argparse based command line tool

the UI has widgets that allow to set up the command line options

argparseui depends on PyQt

State of argparseui

argparseui is a scratch-my-own-itch tool

as such it doesn’t support all possibilities of argparse

use at your own risk, but feel free to log a bug/request

Basic Parser Usage

import argparse
import sys
from PyQt4 import QtGui
import argparseui

# EXPERIMENT USING BASIC PARSER
parser = argparse.ArgumentParser()
parser.add_argument("-m", "--make-argument-true", help="optional boolean argument", action="store_true")
parser.add_argument("-o","--make-other-argument-true", help="optional boolean argument 2", action="store_true",  default=True)
parser.add_argument("-n","--number", help="an optional number", type=int)
parser.add_argument("-r","--restricted-number", help="one of a few possible numbers", type=int, choices=[1,2,3],  default=2)
parser.add_argument("-c", "--counting-argument", help="counting #occurrences", action="count")
parser.add_argument("-d", "--default-value-argument", help="default value argument", type=float, default="3.14")
group = parser.add_mutually_exclusive_group()
group.add_argument("-v", "--verbose", action="store_true")
group.add_argument("-q", "--quiet", action="store_true")
parser.add_argument("posarg", help="positional argument", type=str)

app = QtGui.QApplication(sys.argv)
a = argparseui.ArgparseUi(parser)
a.show()
app.exec_()

if a.result() == 1: # Ok pressed
    parsed_args = a.parse_args() # ask argparse to parse the options
    print parsed_args            # print the parsed_options

# Do what you like with the arguments...

Example using save/load button and keeping the dialog open when pressing ok

import argparse
import sys
from PyQt4 import QtGui
import argparseui

def do_something(argparseuiinstance):
    options = argparseuiinstance.parse_args()
    print ("Options: ", options)

parser = argparse.ArgumentParser()
parser.add_argument("-m", "--make-argument-true", help="optional boolean argument", action="store_true")
parser.add_argument("-o","--make-other-argument-true", help="optional boolean argument 2", action="store_true",  default=True)

app = QtGui.QApplication(sys.argv)
a =     argparseui.ArgparseUi(parser,use_save_load_button=True,ok_button_handler=do_something)
a.show()
app.exec_()
if a.result() != 1:
    # Do what you like with the arguments...
    print ("Cancel pressed")

Extended features

You can pass some extra command line arguments to ArgparseUi:

*helptext_default* = string [default: ' [default=%(default)s]']
this argument can be used to customize the default value annotations in the ui

*remove\_defaults\_from_helptext* = True/False [default: False]
if enabled, this option will remove the default value annotations from
the labels in the ui

*use\_save\_load_button* = True/False [default: False]
if set to True, three extra buttons [Load options, Save Options, Save Options As] appear
the options are saved to (or loaded from) a command line option file in a file format compatible with
argparse's built-in support for loading options from file

*use_scrollbars* = True/False [default: False]
if set to True, the options are embedded in a scrollable panel

*window_title* = string [default: "Make your choice"]
if set to a string, this string will be used as dialog title

*left\_label\_alignment* = True/False [default: None]
if set to True, the checkboxes are left-aligned. This may be useful on platforms
like KDE or MacOsx which by default use right-alignment

*ok\_button\_handler* = function taking one argument [default:None]
if set to None, the dialog will close upon clicking the ok button and its result will be set to 1
if set to a function accepting an ArgparseUi instance as argument, clicking ok will call that function
with "self" as argument

*cancel\_button\_handler* = function taking one argument [default:None]
if set to None, the dialog will close upon clicking cancel and its result will be != 1
if set to a function accepting an ArgparseUi instance as argument, clicking cancel will call that
function with "self" as argument
