dupeguru/README

Contents
=====

This package contains the source for dupeGuru. To learns how to build it, refer to the "Build dupeGuru" section. Below is the description of the various subfolders:

- core: Contains the core logic code for dupeGuru. It's Python code written in TDD style.
- core_*: Edition-specific-cross-toolkit code written in Python.
- cocoa: UI code for the Cocoa toolkit. It's Objective-C code.
- qt: UI code for the Qt toolkit. It's written in Python and uses PyQt. Before redistributing changes in this part of the code, read the "qt/WARNING" file.
- images: Images used by the different UI codebases.

There are also other sub-folder that comes from external repositories (automatically checked out
with svn:externals):

- hscommon: A collection of helpers used across HS applications.
- hsdocgen: An ad-hoc document generation used across HS project (used for help files)
- cocoalib: A collection of helpers used across Cocoa UI codebases of HS applications.
- qtlib: A collection of helpers used across Qt UI codebases of HS applications.

dupeGuru Dependencies
=====

Before being able to build dupeGuru, a few dependencies have to be installed:

General dependencies
-----

- Python 2.6 (http://www.python.org)
- Send2Trash (http://hg.hardcoded.net/send2trash)
- hsutil (http://hg.hardcoded.net/hsutil)
- hsaudiotag (for ME) (http://hg.hardcoded.net/hsaudiotag)
- lxml, to read and write XML files. (http://codespeak.net/lxml/)
- Mako, to generate help files. (http://www.makotemplates.org/)
- PyYaml, for help files and the build system. (http://pyyaml.org/)
- py.test, to run unit tests. (http://codespeak.net/py/dist/test/)

OS X prerequisites
-----

- XCode 3.1 (http://developer.apple.com/TOOLS/xcode/)
- Sparkle (http://sparkle.andymatuschak.org/)
- PyObjC 2.2. (http://pyobjc.sourceforge.net/)
- py2app (http://svn.pythonmac.org/py2app/py2app/trunk/doc/index.html)

Windows prerequisites
---

- Visual Studio 2008 (Express is enough) is needed to build C extensions. (http://www.microsoft.com/Express/)
- PyQt 4.6 (http://www.riverbankcomputing.co.uk/news)
- Python Imaging Library for dupeGuru PE. (http://www.pythonware.com/products/pil/)
- cx_Freeze, if you want to build a exe. You don't need it if you just want to run dupeGuru. (http://cx-freeze.sourceforge.net/)
- Advanced Installer, if you want to build the installer file. (http://www.advancedinstaller.com/)

Building dupeGuru
=====

First, make sure you meet the dependencies listed in the section above. Then you need to configure your build with:

	python configure.py
	
If you want, you can specify a UI to use with the `--ui` option. So, if you want to build dupeGuru with Qt on OS X, then you have to type `python configure.py --ui=qt`. You can also use the `--dev` flag to indicate a dev build (it will build `dg_cocoa.plugin` in alias mode and use the "dev" config in XCode).

Then, just build the thing and then run it with:

	python build.py
	python run.py

If you want to create ready-to-upload package, run:

	python package.py

64-bit on OS X
---

The "release" configuration of dupeGuru's XCode project build with archs "i386 x86_64 ppc". However there are currently problems with py2app and 64 bit. If you want to correctly build 64-bit apps, refer to http://www.hardcoded.net/articles/building-64-bit-pyobjc-applications-with-py2app.htm .
