Mixxx User Manual
This repository contains the sources for the Mixxx User Manual as found at http://mixxx.org/manual/latest/.
First Download the latest Mixxx manual source or clone the repository
$ git clone https://github.com/mixxxdj/manual.git
Next, install the dependencies using pip. From within the repository root
cd manual after typing the above command):
$ pip install -r requirements.txt
If you do not wish to use pip:
- Install Sphinx, the documentation generator.
- Install Graphviz, graph visualization software (used to draw some diagrams)
To upgrade dependencies using pip:
$ pip install -r requirements.txt --upgrade
If you'd like to build manual PDFs, you will need a functioning LaTeX installation.
- On Mac, install MacTeX.
- On Debian-based systems, install
Once you have the repository cloned and dependencies installed you can edit and build the manual to see your changes.
- Edit .rst files in
make htmlto build an HTML version of the manual
- Open the file
build/html/index.htmlin your Web browser to view the results
make linkcheck in the terminal. Sphinx will validate all internal and
external links in the document, and let you know if any links are malformed, or
point to dead URLs.
Guidelines for Mixxx Manual writers
The Mixxx manual is based on sound learning principles, and is supposed to be user-friendly & motivational. Please refer to the guidelines for style conventions:
make htmlto build an HTML version of the manual, then open
build/html/manual_guidelines.htmlin your browser (recommended).
- Alternatively, open https://github.com/mixxxdj/manual/blob/manual/source/manual_guidelines.rst for a quick overview. Github may not render all code correct.
Editing the manual using git (recommended)
- Clone the repository
git clone https://github.com/mixxxdj/manual.git
- Perform changes
- Commit changes
git commit -m "Insert short summary of your changes here"
- Push changes
- Submit a pull request
Editing the manual on Github
- Commit file edits through the GitHub web interface using the Fork and Edit button
- Submit a pull request
The Mixxx manual is translated using the Transifex web service for team translation.
If you did not install requirements with
pip install -r requirements.txt
above then you must manually install the following dependencies:
- sphinx-intl, a utility that makes it easy to translate and compile translations to Sphinx projects.
- transifex-client. Transifex allows collaborative translation via a web interface. The Python-based command line client makes it easy to fetch and push translations.
Install transifex-client on Linux and macOS
$ pip install transifex-client
Install transifex-client on Windows
The easiest way to install it is with pip:
$ easy_install pip $ pip install transifex-client
The first line installs pip on a system level. Then it installs the Transifex Client using pip.
If you do not wish to use pip, download the latest releases from https://github.com/transifex/transifex-client/releases
You will need to make a
.transifexrc in your home directory with your
username and password to use the Transifex client. See
transifex-configuration for more details.
These steps document how to maintain the translations of the Mixxx manual. Typically, unless you are a manual maintainer you do not need to perform these steps. However, it is appreciated if you update the source translations when making changes to the manual.
Update source translations
For every change to the manual source files (.rst) the source translation files
(.pot) must be re-generated. These are stored in
source/locale/pot and contain
the text of every English phrase in the manual in a common format used for
Additionally, for every new source file added (i.e. new chapters or manual
pages) the Transifex configuration file (stored in
.tx/config) needs updating.
To do both of these, run:
Commit the new source translations and Transifex configuration with:
git add source/translations/pot .tx git commit -m "Update source translations and Transifex configuration."
Push source translations to Transifex
After generating new source translation files and updating the Transifex configuration, you must push the new source files to Transifex to be translated.
To do this, run:
Pull completed translations from Transifex
To pull newly completed translation (.po) files from Transifex, run:
Commit the changes to the repository with:
git add source/translations git commit -m "Pull latest translations from Transifex."
Compile the translations from Transifex and verify there are no errors.
To compile the translations (.po) from Transifex into compiled translation (.mo) files, run:
We do not check .mo files into the repository, so make sure you do not add
them (they are ignored by our
To build a translated manual in a particular language:
Note: it's good practice to clean your build directory first:
For example, to build an HTML manual for
fab i18n_build html:language=de-DE
Unless an error occurred, your translated HTML manual is in the
To build a PDF manual:
fab i18n_build pdf:language=de-DE
Your translated PDF manual is located at

ON some systems, using the system package version of pip and running the command
pip install -r requirements.txt might damage the python installation. Concretely, pyopenssl might get damaged and you might get an error saying
'module' object has no attribute 'SSL_ST_INIT'
This happens because the repository has an old version and when installing/updating the requirements, the scripts break.
The solution to fix this consists on deleting the broken files, remove the installed package and install it manually (all commands require access privileges, so use sudo or whatever you need) Fix python:
rm -rf /usr/lib/python2.7/dist-packages/OpenSSL rm -rf /usr/lib/python2.7/dist-packages/pyOpenSSL-0.15.1.egg-info
Remove pip and repair python just in case:
apt-get purge python-pip apt-get install --reinstall python
Install pip manually:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py python get-pip.py
Alternatively, instead of installing pip on the system, you can also install a python-virtualenv and then use PyPI in that virtualenv.
First, in order to have "pip", you need to install python. Python 2.7.12 and onwards already include pip, but you should follow the steps to upgrade it:
python -m pip install -U pip
When installing the required dependencies, you will most probably get an error which says that you need to manually install Visual studio. Concretely, you will see this:
error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27
Follow that link to download an installer named VCForPython27.msi. Also, in that same link, open the "System requirements" section and download the x86 or x64 (or both) version of the Microsoft Visual C++ runtimes.
