dupeGuru

dupeGuru is a cross-platform (Linux, OS X, Windows) GUI tool to find duplicate files in a system. It is 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 is written in Python and uses Qt5.

The Cocoa UI of dupeGuru is hosted in a separate repo: https://github.com/arsenetar/dupeguru-cocoa

Current status

2020: various bug fixes and small UI improvements have been added. Packaging for MacOS is still a problem.

Still looking for additional help especially with regards to:

OSX maintenance: reproducing bugs & cocoa version, building package with Cocoa UI.
Linux maintenance: reproducing bugs, maintaining PPA repository, Debian package.
Translations: updating missing strings.
Documentation: keeping it up-to-date.

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 organized:

core: Contains the core logic code for dupeGuru. It's Python 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 localization.
hscommon: A collection of helpers used across HS applications.
qtlib: A collection of helpers used across Qt UI codebases of HS applications.

How to build dupeGuru from source

Windows & macOS specific additional instructions

For windows instructions see the Windows Instructions.

For macos instructions (qt version) see the macOS Instructions.

Prerequisites

Python 3.6+
PyQt5

System Setup

When running in a linux based environment the following system packages or equivalents are needed to build:

python3-pyqt5
python3-wheel (for hsaudiotag3k)
python3-venv (only if using a virtual environment)
python3-dev
build-essential

Note: On some linux systems pyrcc5 is not put on the path when installing python3-pyqt5, this will cause some issues with the resource files (and icons). It can be checked by running which pyrcc5. If there is no result, before building install pyqt5 just into the virtual environment via pip. (It has not been added to the requirement files at this time on linux due to issues caused in the CI builds if this is done.)

To create packages the following are also needed:

python3-setuptools
debhelper

Building with Make

dupeGuru comes with a makefile that can be used to build and run:

$ make && make run

Building without Make

$ cd <dupeGuru directory>
$ python3 -m venv --system-site-packages ./env
$ source ./env/bin/activate
$ pip install -r requirements.txt
$ python build.py
$ python run.py

Generating Debian/Ubuntu package

To generate packages the extra requirements in requirements-extra.txt must be installed, the steps are as follows:

$ cd <dupeGuru directory>
$ python3 -m venv --system-site-packages ./env
$ source ./env/bin/activate
$ pip install -r requirements.txt -r requirements-extra.txt
$ python build.py --clean
$ python package.py

This can be made a one-liner (once in the directory) as:

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

Running tests

The complete test suite is run 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
