dupeGuru

dupeGuru is a cross-platform (Linux and OS X) GUI tool to find duplicate files in a system. It's written mostly in Python 3 and has the peculiarity of using multiple GUI toolkits, all using the same core Python code. On OS X, the UI layer is written in Objective-C and uses Cocoa. On Linux, it's written in Python and uses Qt5.

Current status: People wanted

dupeGuru has currently only one maintainer, me. This is a dangerous situation that needs to be corrected.

The goal is to eventually have another active maintainer, but before we can get there, the project needs more contributors. It is very much lacking on that side right now.

Whatever your skills, if you are remotely interestested in being a contributor, I'm interested in mentoring you. If that's the case, please refer to the open ticket on the subject and let's get started.

Slowed development

Until I manage to find contributors, I'm slowing the development pace of dupeGuru. I'm not much interested in maintaining it alone, I personally have no use for this app (it's been a loooong, time since I had dupe problems :) )

I don't want to let it die, however, so I will still do normal maintainership, that is, issue triaging, code review, critical bugfixes, releases management.

But anything non-critical, I'm not going to implement it myself because I see every issue as a contribution opportunity.

Windows maintainer wanted

As described on my website, dupeGuru v4.0 dropped Windows support because there isn't anyone to bear the burden of Windows maintenance. If you're a Windows developer and are interested in taking this task, don't hesitate to let me know.

OS X maintainer wanted

My Mac Mini is already a couple of years old and is likely to be my last Apple purchase. When it dies, I will be unable maintain the OS X version of moneyGuru. I've already stopped paying for the Mac Developer membership so I can't sign the apps anymore (in the "official way" I mean. The download is still PGP signed) If you're a Mac developer and are interested in taking this task, don't hesitate to let me know.

Contents of this folder

This folder contains the source for dupeGuru. Its documentation is in help, but is also available online in its built form. Here's how this source tree is organised:

• core: Contains the core logic code for dupeGuru. It's Python code.
• 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.
• images: Images used by the different UI codebases.
• pkg: Skeleton files required to create different packages
• help: Help document, written for Sphinx.
• locale: .po files for localisation.

There are also other sub-folder that comes from external repositories and are part of this repo as git submodules:

• hscommon: A collection of helpers used across HS applications.
• 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.

How to build dupeGuru from source

make

If you're on linux, you can build the ap for local development with make:

$ make
$ make run

The Makefile is a recent addition, however. You might have to fallback to the legacy build scripts.

Legacy build

If you're on OS X or that if the make method didn't work, you can build dupeGuru with the legacy scripts.

There's a bootstrap script that will make building very easy. There might be some things that you need to install manually on your system, but the bootstrap script will tell you when what you need to install. You can run the bootstrap with:

$ ./bootstrap.sh

and follow instructions from the script.

Prerequisites installation

Prerequisites are installed through pip. However, some of them are not "pip installable" and have to be installed manually.

• All systems: Python 3.4+
• Mac OS X: OS X 10.10+ with XCode command line tools.
• Linux: PyQt5

On Ubuntu (14.04+), the apt-get command to install all pre-requisites is:

$ apt-get install python3-dev python3-pyqt5 pyqt5-dev-tools python3-venv

OS X and pyenv

pyenv is a popular way to manage multiple python versions. However, be aware that dupeGuru will not compile with a pyenv's python unless it's been built with --enable-framework. You can do this with:

$ env PYTHON_CONFIGURE_OPTS="--enable-framework" pyenv install 3.4.3

Setting up the virtual environment

This is done automatically by the bootstrap script. This is a reference in case you need to do it manually.

Use Python's built-in pyvenv to create a virtual environment in which we're going to install our. Python-related dependencies. In that environment, we then install our requirements with pip.

For Linux (--system-site-packages is to be able to import PyQt):

$ pyvenv --system-site-packages env
$ source env/bin/activate
$ pip install -r requirements.txt

For OS X:

$ pyvenv  env
$ source env/bin/activate
$ pip install -r requirements-osx.txt

Actual building and running

With your virtualenv activated, you can build and run dupeGuru with these commands:

$ python build.py
$ python run.py

You can also package dupeGuru into an installable package with:

$ python package.py

Generate Ubuntu packages

$ bash -c "pyvenv --system-site-packages env && source env/bin/activate && pip install -r requirements.txt && python3 build.py --clean && python3 package.py"

Running tests

The complete test suite is ran with Tox 1.7+. If you have it installed system-wide, you don't even need to set up a virtualenv. Just cd into the root project folder and run tox.

If you don't have Tox system-wide, install it in your virtualenv with pip install tox and then run tox.

You can also run automated tests without Tox. Extra requirements for running tests are in requirements-extra.txt. So, you can do pip install -r requirements-extra.txt inside your virtualenv and then py.test core hscommon
