eGenix PyRun - One file Python Runtime

Version 1.2.0

An easy-to-use single file relocatable Python run-time -
available for Windows, Mac OS X and Unix platforms

This announcement is also available on our web-site for online reading:



Our new eGenix PyRun combines a Python interpreter with an almost
complete Python standard library into a single easy-to-use executable,
that does not require a system wide installation and is fully

eGenix PyRun's executable only needs 11MB, but still supports most
Python application and scripts - and it can be further compressed to
just 3-4MB using upx.

Compared to a regular Python installation of typically 100MB on disk,
this makes eGenix PyRun ideal for applications and scripts that need
to be distributed to many target machines, client installations or

It makes "installing" Python on a Unix based system as simple as
copying a single file.

We have been using the product internally in our mxODBC Connect Server
since 2008 with great success and have now extracted it into a
stand-alone open-source product.

We provide both the source archive to build your own eGenix PyRun, as
well as pre-compiled binaries for Linux, FreeBSD and Mac OS X, as 32-
and 64-bit versions.

Please see the product page for more details:



This is a new minor release of eGenix PyRun, which contains a few
important fixes and enhancement based on the user feedback in recent

New Features

* Upgraded eGenix PyRun to work with and use Python 2.7.4 per

* Changed the pyrun default to run in non-optimized mode and added
the -O command line option to reenable it.

Previous versions of eGenix PyRun used to default to optimized
mode, which prevented running tests using e.g. assert with it. The
stdlib itself is still frozen in optimized mode.

* Added support for directly running Python directories and ZIP files
with __main__ module. Only works with the Python 2.7 variant.

* eGenix PyRun now honors symlinks, so symlinked copies of PyRun can
be used to save disk space. The installations will still work as
expected, i.e. independent of each other.

* Added new pyrun_release config variable to the pyrun_config
module. This allows checking the pyrun release version.

* Added PyRun release version to the banner and -V output.

* Added support for the Python -d command line option to pyrun.

* Added a fix to allow PyRun to compile the sqlite module on Mac OS X
10.4. See for details.

* Much enhanced documentation, which now also explains the internals
and highlights Python modules/packages that are not included in
eGenix PyRun.

Other Changes

* Removed the compiler package from being compiled into PyRun. If
needed, it can be installed separately. Note that the compiler
package needs the parser module which is not compiled into PyRun
either, but is still available as extension module.

* Removed the Tkinter Python module from being compiled into
PyRun. If needed, it can be installed separately. Note that the
Tkinter module needs the _tkinter C module, which is not compiled
into PyRun either, but is still available as extension module.

* Fixed sys.argv when using interactive mode to default to [''].

* All eGenix PyRun distribution packages are now GPG signed with our
release key and come with MD5 and SHA1 hashes to check for download

install-pyrun Quick Installation Enhancements

Since version 1.1.0, eGenix PyRun includes a shell script called
install-pyrun, which greatly simplifies installation of eGenix
PyRun. It works much like the virtualenv shell script used for
creating new virtual environments (except that there's nothing virtual
about PyRun environments).

With the script, an eGenix PyRun installation is as simple as running:

./install-pyrun targetdir

We have enhanced this script somewhat since the last release and also
added it to the source code distribution of eGenix PyRun:

* Added new options --distribute-distribution and --pip-distribution
to be able to use local distribution files for distribute and pip.

* Added --debug option to enable debug output.

* install-pyrun will now try uname -m in case uname -p doesn't return
useful information about the platform.

* install-pyrun will now use HTTPS connections for all tools (pyrun,
distribute and pip). SSL certificate checking is enabled per
default, but can be turned off using the new
--disable-certificate-checks option.

* Added automatic support for wget to install-pyrun. It is being used
if curl is not found on the system.

* Added new option --platform-list to print a list of available
platform strings.
