Change Log

• Fixed a bug in codegen.py that was putting raw ast objects in the code output.
• Rewrote parser to make future changes easier. Issue 18
• Fixed a bug in the parser that was missing certain import types.
• Added Restart Button. Issue #20 (hacked it in there ;) need to pretty it up later.)
• Fixed bug in language class.

Planned Features:

• Language agnostic support -- a stand-alone Gooey to build other Gooies!
• docopt support -- The people demand it!
• Ability to customize widgets (e.g. FileChooser instead of TextBox)
• Stop/cancel button on run screen

##Quick Start

###Installation instructions

To install Gooey, simply clone the project to your local directory

git clone https://github.com/chriskiehl/Gooey.git

###Usage

Gooey is attached to your code via a simple decorator on your main method.

from gooey import Gooey

@Gooey      <--- all it takes! :)
def main():
  # rest of code

Different styling and functionality can be configured by passing arguments into the decorator.

# options
@Gooey(advanced=Boolean,          # toggle whether to show advanced config or not 
       language=language_string,  # Translations configurable via json
       config=Boolean,            # skip config screens all together
       program_name='name',       # Defaults to script name 
       program_description        # Defaults to ArgParse Description
  )
def main():
  # rest of app

See: How does it Work section for details on each option.

What is it?

Gooey converts your Console Applications into end-user-friendly GUI applications. It lets you focus on building robust, configurable programs in a familiar way, all without having to worry about how it will be presented to and interacted with by your average user.

Why?

Because as much as we love the command prompt, the rest of the world looks at it like some kind of ugly relic from the early '80s. On top of that, more often than not programs need to do more than just one thing, and that means giving options, which previously meant either building a GUI, or trying to explain how to supply arguments to a Console Application. Gooey was made to (hopefully) solve those problems. It makes programs easy to use, and pretty to look at!

Who is this for?

If you're building utilities for yourself, other programmers, or something which produces a result that you want to capture and pipe over to another console application (e.g. *nix philosophy utils), Gooey probably isn't the tool for you. However, if you're building 'run and done,' around-the-office-style scripts, things that shovel bits from point A to point B, or simply something that's targeted at a non-programmer, Gooey is the perfect tool for the job. It lets you build as complex of an application as your heart desires all while getting the GUI side for free.

How does it work?

Gooey is attached to your code via a simple decorator on your main method.

@Gooey      <--- all it takes! :)
def main():
  # rest of code

At run-time, it loads the Abstract Syntax Tree for your module and parses it for all references to ArgumentParser. (The older optparse is currently not supported.) These references are then extracted, assigned a component type based on the 'action' they provide, and finally used to assemble the GUI.

####Mappings:

Currently, the ArgumentParser._actions are mapped to the following WX components.

Parser Action	Widget	Example
store	TextCtrl
store_const	CheckBox
store_true	CheckBox
store_False	CheckBox
append	TextCtrl
count	DropDown
choice	DropDown

---

Configuration

Gooey comes in three main flavors.

• Full/Advanced
• Basic
• No config

Each has the following options:

Parameter	Summary
language	Gooey is (kind of) international ready (sans Unicode issues (TODO)). All program text is stored in an external json file. Translating to your host language only requires filling in the key/value pairs.
program_name	The name displayed in the title bar of the GUI window. If the value is None, the title is pulled from sys.argv[0].
program_description	Sets the text displayed in the top panel of the Settings screen. If None the description is pulled from the ArgumentParser.

###Advanced

The default view is the "full" or "advanced" configuration screen. It can be toggled via the advanced parameter in the Gooey decorator.

@gooey(advanced=True)
def main():
    # rest of code   

This view presents each action in the Argument Parser as a unique GUI component. This view is ideal for presenting the program to users which are unfamiliar with command line options and/or Console Programs in general. Help messages are displayed along side each component to make it as clear as possible which each widget does.

---

###Basic

The basic view is best for times when the user is familiar with Console Applications, but you still want to present something a little more polished than a simple terminal. The basic display is accessed by setting the advanced parameter in the gooey decorator to False.

@gooey(advanced=False)
def main():
    # rest of code  

---

###No Config

No Config pretty much does what you'd expect: it doesn't show a configuration screen. It hops right to the display section and begins execution of the host program. This is the one for improving the appearance of little one-off scripts.

TODO

• Add to pypi
• Themes
• Add ability to customize the mapping between Parser actions and wxComponents. For instance, if your program had a file as a required argument, it'd be far more useful to the end user to supply a wx.FileDialog rather than a simple TextBox.
• Update graphics
• Optparse support?
• Get OS X version working.

Wanna help?

• Do you art? I'd love to swap out the graphics to something more stylistically unified.

• Programmer? Pull requests are super welcome. The projects' style is fantastically inconsistent, though. So be warned :) I tried to follow the WxWidgets style of Leading Capital methods and CamelCased variables, but.. Python habits die hard. So, there are underscores littered all over the place.
