GravityBee helps you generate standalone applications for Windows,
Mac, and Linux from your Python applications.

GravityBee is targeted at Python
programs that are already packaged in the standard setuptools
way.

These are some benefits of a GravityBee standalone application:

* You end up with one file that contains everything.
* Your users do not need Python or any packages installed.
* You build separate natively executable applications for each of
  your target platforms.

GravityBee depends on `Pyppyn <https://github.com/plus3it/pyppyn>`_ and
`PyInstaller <http://www.pyinstaller.org>`_ and is subject to their limitations.

To Build A Standalone Application
=================================

Step 1 - Install
----------------

You must install the application you wish to build (e.g.,
``yoursuperapp``), as well as GravityBee.

.. code-block:: bash

    $ pip install yoursuperapp gravitybee

The process will also work fine if you're installing from a local
version of your app.

.. code-block:: bash

    $ cd yoursuperapp
    $ ls setup*
    setup.cfg            setup.py
    $ pip install --editable .
    $ pip install gravitybee

Step 2 - Provide (or gather) information
----------------------------------------

GravityBee will assume all necessary information when run. However,
you may wish to override the assumed
values. You can provide values either through environment variables
or command line flags. If both are
provided, command line flags take precedence.

Local logging can be configured in ``gravitybee/logging.conf``.

                                                final standalone application name.
                                                *Default:* ``name`` *from setup.py and/or

                                                ``pip`` when you installed
                                                your application. Depending on your
                                                configuration, this may be determined by
                                                ``options.entry_points.console_scripts`` from
                                                ``setup.py`` and/or ``setup.cfg``.

                                                This directory must contain a
                                                ``setup.py`` file.

                                                to be included, that wouldn't normally
                                                be included as Python code. Can be
                                                used multiple times.
                                                *Default: None*

                                                directory as it will be deleted if the
                                                clean voption is used.

                                                is not compatible with producing a SHA
                                                hash since a hash is produced on a
                                                single file. This option may be useful
                                                for debugging runtimes errors in built
                                                applications.

                                                info output). *Default:* ``info``
GB_STAGING_DIR          --staging-dir           Option to indicate where GravityBee
                                                should stage build artifacts
                                                (standalone executable and hash
                                                file). Two subdirectories can
                                                be created, one based on version

                                                *Default:* ``.gravitybee/dist``
GB_WITH_LATEST          --with-latest           Flag to indicate if GravityBee
                                                should create a "latest"
                                                directory in the staging area
                                                with a copy of the artifacts.
                                                *Default: Not*
GB_INCLUDE_SETUP_EXTRAS --include-setup-extras  Includes any 'extras' modules listed in
                                                setup.py/cfg standalone application. (Such as
                                                packages marked 'build', 'docs', 'check', etc.)
                                                *Default: False*
GB_EXTRA_MODULES        --extra-modules         Any extra modules to be included with
                                                the standalone executable.
                                                *Default: None*
GB_EXTRA_PKGS           --extra-pkgs            Any extra packages to be included with
                                                the standalone executable.
                                                *Default: None*
VIRTUAL_ENV                                     If using conda env set VIRTUAL_ENV to
                                                conda env directory
======================= ======================  ==========================================

If you are using environment variables, you could set them up like
this.

.. code-block:: bash

    $ export GB_APP_NAME=coolapp
    $ export GB_PKG_NAME=coolapp
    $ export GB_SCRIPT=/usr/var/python/etc/coolapp


Step 3 - Generate
-----------------

Creating the standalone application is easy now.

.. code-block:: bash

    $ gravitybee

If you are not using environment variables, you can combine steps 2 and 3.

.. code-block:: bash

    $ gravitybee --app-name coolapp --script /usr/var/python/etc/coolapp --pkg-dir coolapp

Output Files
------------

If the ``--no-file`` flag is not used, GravityBee will create output
files. These include:

* **gravitybee-files.json**: A JSON file that contains information
  about the standalone application generated by GravityBee including
  ``filename``, ``path``, ``mime-type``, and ``label`` as a list of
  dicts.
* **gravitybee-info.json**: A JSON file that contains information
  extracted
  about the application including ``app_name``, ``app_version``,
  ``console_script``,
  ``script_path``, ``pkg_dir``, ``src_dir``, ``name_format``,
  ``clean``, ``work_dir``,
  ``gen_file``, ``gen_file_w_path``, and ``extra_data``.
* **gravitybee-environs.sh**: A shell file that can be sourced on
  POSIX platforms
  to create environment variables with GravityBee information. Each
  is prefixed
  with ``GB_ENV_``.
* **gravitybee-environs.bat**: A batch file that can be used to
  create environment variables with GravityBee information on
  Windows. Each
  environ is prefixed with ``GB_ENV_``.


The Test Example
----------------

Here is the file/package structure of the included
`test application <https://github.com/plus3it/gravitybee/tree/dev/tests/gbtestapp>`_.

.. code-block:: bash

    gbtestapp
    |-- setup.py
    |-- setup.cfg
    >-- src
    |   >-- gbtestapp
    |       |-- __init__.py
    |       |-- cli.py
    |       >-- gbextradata
    |           |-- __init__.py
    |           |-- data_file.txt

You would build the application as follows. Since the application
package is under the ``src`` directory, you need to let GravityBee
know. Also, since we need to include the ``data_file.txt`` file,
we'll use the ``--extradata`` option to include the containing
directory (``gbextradata``).

.. code-block:: bash

    $ cd gbtestapp
    $ gravitybee --src-dir src --extra-data gbextradata --clean


From Python Example
-------------------

Using GravityBee from a Python script is also possible. Using the
sample test app, here's some example code.

.. code-block:: python

    import gravitybee

    args = gravitybee.Arguments(
        src_dir="src",
        extra_data=["gbextradata"],
        pkg_dir=os.path.join("tests", "gbtestapp"),
        clean=True
    )

    pg = gravitybee.PackageGenerator(args)
    pg.generate()

    # show path (and name) of standalone app
    print("The standalone app: ", pg.gen_file_w_path)
