Again Selector

==============

When you push to try, the computed ``try_task_config.json`` is saved in a

history file under ``~/.mozbuild/srcdirs/<srcdir hash>/history`` (note: the

``syntax`` selector does not use ``try_task_config.json`` yet so does not save

any history). You can then use the ``again`` selector to re-push any of your

previously generated task configs.

In the simple case, you can re-run your last try push with:

.. code-block:: shell

    $ mach try again

If you want to re-push a task config a little further down the history stack,

first you need to figure out its index with:

.. code-block:: shell

    $ mach try again --list

Then run:

.. code-block:: shell

    $ mach try again --index <index>

Note that index ``0`` is always the most recent ``try_task_config.json`` in the

history. You can clear your history with:

.. code-block:: shell

    $ mach try again --purge

Only the 10 most recent pushes will be saved in your history.
