===
dev
===
Run the application in developer mode.
Usage
=====
To run your application in development mode on the current platform's default output format:
.. code-block:: console
$ briefcase dev
To run your application for a different platform:
.. code-block:: console
$ briefcase dev <platform>
To run your application using a specific output format:
.. code-block:: console
$ briefcase dev <platform> <output format>
The first time the application runs in developer mode, any requirements listed in a
:attr:`requires` configuration item in ``pyproject.toml`` will be installed into the
current environment.
Options
=======
The following options can be provided at the command line.
``-a <app name>`` / ``--app <app name>``
----------------------------------------
Run a specific application target in your project. This argument is only
required if your project contains more than one application target. The app
name specified should be the machine-readable package name for the app.
``-r`` / ``--update-requirements``
----------------------------------
Update application requirements.
``--no-run``
------------
Do not run the application; only install application requirements.
``--test``
----------
Run the test suite in the development environment.
Passthrough arguments
---------------------
If you want to pass any arguments to your app's command line, you can specify them
using the ``--`` marker to separate Briefcase's arguments from your app's arguments.
For example:
.. code-block:: console
$ briefcase dev -- --wiggle --test
will run the app in normal mode, passing the ``--wiggle`` and ``--test`` flags to
the app's command line. The app will *not* run in *Briefcase's* test mode; the
``--test`` flag will be left for your own app to interpret.
