Note

The Developer menu is available if Mixxx is started using the Command line options.

13.3. Command line options

Mixxx is designed to be as user-friendly as possible. As such, its command line options are only useful for development or debugging, as they make these tasks easier. Command line options are case-sensitive.

    New in version 2.0:
  • Show debug tooltips

  • Provide extra skins when developer mode is enabled.

  • Adds the debugger during skin parsing in --developer mode

  • Adds „Enable Base” and „Enable Experiment” option in --developer mode

  • Added --safeMode option.

Option

Description

[FILE]

Load the specified music file(s) at start-up. Each file you specify will be loaded into the next virtual deck. Supported file types: mp3, ogg, aiff, aif, wav, flac, and optional unprotected aac (m4a)

–resourcePath PATH

Top-level directory where Mixxx should look for its resource files such as MIDI mappings, overriding the default installation location.

–pluginPath PATH

Top-level directory where Mixxx should look for sound source plugins in addition to default locations.

–settingsPath PATH

Top-level directory where Mixxx should look for user settings files such as the library database and preferences configuration file.

–controllerDebug

Causes Mixxx to display/log all controller data it receives and script functions it loads.

–developer

Enables developer-mode. Includes extra log info, stats on performance, a Developer tools menu, extra developer skins, and provides useful information for skin writers in widget tooltips and logs .

–safeMode

Disables risky things at start up. This should help troubleshoot crashes at startup or if Mixxx won’t boot.

  • Automatically loads empty waveforms

  • Disables spinning vinyl widgets

  • Disables synchronization polling

  • Doesn’t open controllers by default

–locale LOCALE

Use a custom locale for loading translations (e.g ’fr’)

-f, –fullScreen

Starts Mixxx in full-screen mode

-h, –help

Display this help message and exit

13.4. Developer tools

To start Mixxx in Developer mode from a custom resource directory with MIDI and HID logging enabled, type the following line into the terminal and hit return:

./mixxx --controllerDebug --developer --resourcePath res

13.4.1. Experiment modes for rapid development and testing

    New in version 2.0:
  • Adds a static Experiment class with a tri-state mode flag that indicates whether the experiment mode is OFF, BASE, or EXPERIMENT.

  • Adds Developer‣Stats:Experiment Bucket and Developer‣Stats:Base Bucket. Each one toggles between OFF and BASE/EXPERIMENT so you can choose exactly what time spans you would like to collect in your base and experiment buckets.

  • Updates StatsManager to segment collected stats into a base and experiment bucket. This allows you to quickly measure the difference a code change has on relevant counters / timers within the same execution of Mixxx.

This is useful for quickly enabling and disabling a code change without a re-compile/re-run cycle to get an anecdotal sense of how it „feels” as well as a quantified sense of how it differs in terms of stats Mixxx collects.

All stats collected via the usual Counter/Timer/ScopedTimer/etc. tools are segmented into a BASE STATS and EXPERIMENT STATS section printed to the log on exit.
