Consejo

The Ctrl key on Windows & Linux is equivalent to the Command key on macOS. The Alt key on Windows & Linux is equivalent to the Option key on macOS. Application shortcuts are not customizable.

Nota

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

16.4. 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.

Nuevo en la versión 2.1.0:

  • --debugAssertBreak option

  • --logLevel option

  • --logFlushLevel option

Distinto en la versión 2.1.0:

  • --controllerDebug option also prints outgoing MIDI messages

Option

Description

[FILE]

Load the specified music file(s) at start-up. Each file you specify will be loaded into the next virtual deck. For a list of supported file types, go to Changing music directories

–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 sends and 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

–logLevel LEVEL

Sets the verbosity of command line logging

  • critical - Critical/Fatal only

  • warning - Above + Warnings

  • info - Above + Informational messages

  • debug - Above + Debug/Developer messages

  • trace - Above + Profiling messages

–logFlushLevel LEVEL

Sets the the logging level at which the log buffer is flushed to mixxx.log. LEVEL is one of the values defined at --logLevel above.

–debugAssertBreak

Breaks (SIGINT) Mixxx, if a DEBUG_ASSERT evaluates to false. Under a debugger you can continue afterwards. This will also avoid to switch the MIXXX_DEBUG_ASSERTIONS_FATAL flag which leads to a time consuming full rebuild. Now the MIXXX_DEBUG_ASSERTIONS_FATAL is only respected if --debugAssertBreak is not passed.

-h, –help

Display this help message and exit

16.5. 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

16.5.1. Experiment modes for rapid development and testing

  • 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.
