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 uses qt for the UI.

Current status

Still looking for additional help especially with regards to:

• OSX maintenance: reproducing bugs, packaging verification.
• Linux maintenance: reproducing bugs, maintaining PPA repository, Debian package, rpm package.
• Translations: updating missing strings, transifex project at https://www.transifex.com/voltaicideas/dupeguru-1
• 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.

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 3.7+
• PyQt5

System Setup

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

• python3-pyqt5
• pyqt5-dev-tools (on some systems, see note)
• 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). These systems should have a respective pyqt5-dev-tools package, which should also be installed. The presence of pyrcc5 can be checked with which pyrcc5. Debian based systems need the extra package, and Arch does not.

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
