Pyload

======
Pyload
======


	Binary static generator for python apps*


Synopsis
--------

For distribution purposes many times you want to compile all your python
code into a one unique static linked binary, like other languages (i.e.
golang) does. While python do not support a native way to do this,

	*pyload** can help you in that job.


Pyload is just a small binary (compiled for some architectures for now),
which simply loads a ZIP file from the same binary, and run it via
`zipimport <https://docs.python.org/3.4/library/zipimport.html>`_ module.

The python binary code (libpython) is statically linked to the pyload
binary, and required standard libraries are also provided inside the binary
too. PyLoad do not use any temporary directory to decompress ZIP, but load
files on-the-fly.

If you are interesting in knowing more about how pyload works, please read
the INTERNALS_ documentation page.

Installation
------------

Just install as any other python package::

  easy_install pyload

Please note that pyload only works in x86_64 architecture on Linux systems.


Usage
-----

Just type::

  pyload <package>

Where package could by any pip valid package, like file path, a tar.gz file,
a git repository and so on...

You can also create a binary for single python script::

  pyload -s <file.py>

Note that in that case you cannot get any dependencies automagically, and
you need to specify them with ``--include`` flag.

Other valid options are available typing ``pyload -h``.

Run examples
------------

Go to ``examples/`` and run::

  make

Then you see the results in ``out/``.

Limitations
-----------

1. Pyload always create binaries for that package, that means that if other
   console scripts provide for any dependency of the package is declared,
   then will be created also. You can filter what binary do you want using
   ``--binary`` flag.

2. Some packages does not include some *basic* dependencies, like
   setuptools, distribute and similar. In that case pyload generate binary
   should fail. You need to add these modules by hand (because pyload only
   get dependencies from dependencies listed in the package) using
   ``--include``.

3. Some libraries and applications do not load resources from the package
   using ``pkg_resources`` package, but try to open file directly using
   ``open`` builtin. There are many reasons to avoid it in your python apps,
   but if you need to deal with it, you probably need to use the ``--patch``
   flag.

Contributions
-------------
Bug reports and code and documentation patches are greatly appretiated. You
can also help by using the development version of Pyload and reporting any
bugs you might encounter.


	*It's important that you provide the full command argument list as well as

the output of the failing command.**

Before working on a new feature or a bug, please browse `existing issues`_ to
see whether it has been previously discussed. If the change in question is
a bigger one, it's always good to discuss before your starting working on
it.

Please for any PR or change in the code, try to follow the  `Style Guide for
Python Code (PEP8) <http://python.org/dev/peps/pep-0008/>`_.
