User Guide
==========

Mach is the central entry point for most operations that can be performed in
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 These generated scripts will slowly become out of date over time, so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.

See below for installation instructions:

Bash
~~~~

.. code-block:: shell

    $ mach mach-completion bash -f _mach
    $ sudo mv _mach /etc/bash_completion.d

Bash (homebrew)
~~~~~~~~~~~~~~~

.. code-block:: shell

    $ mach mach-completion bash -f $(brew --prefix)/etc/bash_completion.d/mach.bash-completion

Zsh
~~~

.. code-block:: shell

    $ mkdir ~/.zfunc
    $ mach mach-completion zsh -f ~/.zfunc/_mach

then edit ~/.zshrc and add:

.. code-block:: shell

    fpath+=~/.zfunc
    autoload -U compinit && compinit

You can use any directory of your choosing.

Zsh (oh-my-zsh)
~~~~~~~~~~~~~~~

.. code-block:: shell

    $ mkdir $ZSH/plugins/mach
    $ mach mach-completion zsh -f $ZSH/plugins/mach/_mach

then edit ~/.zshrc and add 'mach' to your enabled plugins:

.. code-block:: shell

    plugins(mach ...)

Zsh (prezto)
~~~~~~~~~~~~

.. code-block:: shell

    $ mach mach-completion zsh -f ~/.zprezto/modules/completion/external/src/_mach

Fish
~~~~

.. code-block:: shell

    $ ./mach mach-completion fish -f ~/.config/fish/completions/mach.fish

Fish (homebrew)
~~~~~~~~~~~~~~~

.. code-block:: shell

    $ ./mach mach-completion fish -f (brew --prefix)/share/fish/vendor_completions.d/mach.fish

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

.. _bash completion: https://searchfox.org/mozilla-central/source/python/mach/bash-completion.sh
