|
|
mozilla-central.

Command Help
|
|
------------
|
|
|
|
To see an overview of all the available commands, run:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ ./mach help
|
|
|
|
For more detailed information on a specific command, run:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ ./mach help <command>
|
|
|
|
If a command has subcommands listed, you can see more details on the subcommand
|
|
by running:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ ./mach help <command> <subcommand>
|
|
|
|
Alternatively, you can pass ``-h/--help``. For example, all of the
|
|
following are valid:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ ./mach help try
|
|
$ ./mach help try fuzzy
|
|
$ ./mach try -h
|
|
$ ./mach try fuzzy --help
|

Tab Completion
|
|
--------------
|
|
|
|
There are commands built-in to ``mach`` that can generate a fast tab completion
|
|
script for various shells. Supported shells are currently ``bash``, ``zsh`` and
|
|
``fish``. These generated scripts will slowly become out of date over time, so
|
|
you may want to create a cron task to periodically re-generate them.
|
|
|
|

User Settings
|
|
-------------
|
|
|
|
Some mach commands can read configuration from a ``machrc`` file. The default
|
|
location for this file is ``~/.mozbuild/machrc`` (you'll need to create it).
|
|
This can also be set to a different location by setting the ``MACHRC``
|
|
environment variable.
|
|
|
|
For a list of all the available settings, run:
|
|
|
|
.. code-block:: shell
|
|
|
|
$ ./mach settings
|
|
|
|
The settings file follows the ``ini`` format, e.g:
|
|
|
|
.. code-block:: ini
|
|
|
|
[alias]
|
|
eslint = lint -l eslint
|
|
|
|
[build]
|
|
telemetry = true
|
|
|
|
[try]
|
|
default = fuzzy
