Chooser Selector

When pushing to try, there are a very large amount of builds and tests to choose from. Often too many to remember, making it easy to forget a set of tasks which should otherwise have been run.

This selector allows you to select tasks from a web interface that lists all the possible build and test tasks and allows you to select them from a list. It is similar in concept to the old try syntax chooser page, except that the values are dynamically generated using the :ref:`taskgraph<TaskCluster Task-Graph Generation>` as an input. This ensures that it will never be out of date.

To use:

$ mach try chooser

This will spin up a local web server (using Flask) which serves the chooser app. After making your selection, simply press Push and the rest will be handled from there. No need to copy/paste any syntax strings or the like.

You can run:

$ mach try chooser --full

To generate the interface using the full :ref:`taskgraph<TaskCluster Task-Graph Generation>` instead. This will include tasks that don't run on mozilla-central.
