pypokereval packaging for fpdb project
--------------------------------------

Background
----------
The walktrough builds an unoffical python installer package for pypokereval.
In a previous walkthrough, the pypokereval dll(pyd) was built from source.
In this walkthrough, we are going to generate a windows package which will allow
the sources to be installed through distutils onto a client computer
The current situation is that there is no windows build or windows installer provided
by the package authors.
Until a package is available, the fpdb project needs some method of providing a windows
installation for the pypokereval module. This walkthrough will therefore be obsolete once
an official package becomes available.
Actually, for windows fpdb users, the majority will use a pre-built fpdb executable (which contains the
pypokereval package) Therefore, pypokereval installation will only be needed for two groups of people:
i) anyone wanting to build an fpdb package using py2exe
ii) anyone wanting to run fpdb on windows from source

Assumptions
-----------
The underlying dll(pyd) and pokereval library is built for win32 x86 platform only, so we will assume
32bit only in this walkthrough. Contributions for a x86-64 build are most welcome.
Similarly, the underlying package is built against the python 2-6 library and is valid only for that version.
The underlying package was not built with sse enabled, and therefore should work for legacy systems.
1. Install pre-requisites
-------------------------
System used for building is winXP home
1.1/ Install python runtime from here ...
Python 2.6.5 ... http://www.python.org/ftp/python/2.6.5/python-2.6.5.msi
1.2/ Grab pypokereval stuff from fpdb project here ...
pypokereval ... http://sourceforge.net/projects/fpdb/files/fpdb/pypoker-eval-win32/pypokereval-138-win32-py265-fpdb-1.1.exe/download
1.3/ Double click the pypokereval-138-win32-py265-fpdb-1.1.exe and extract the folder to the desktop
2. Prepare a folder containing the items needing packaging
----------------------------------------------------------
dos>cd desktop
dos>mkdir pypokereval138-installer-win32-py265-fpdb
dos>cd pypokereval138-installer-win32-py265-fpdb
dos>mkdir payload
dos>cd payload
dos>copy ..\..\pypokereval-138-win32-py265-fpdb-1.1\_pokereval_2_6.pyd
dos>copy ..\..\pypokereval-138-win32-py265-fpdb-1.1\pokereval.py
dos>mkdir utils
dos>cd utils
dos>copy ..\..\..\pypokereval-138-win32-py265-fpdb-1.1\test.py
dos>cd ..
The next step is to rename the pokereval.py file to __init__.py. The reason for doing this
is that site-packages require an __init__ file to be found when the module is imported at runtime
Inserting a dummy __init__.py which simply imports pokereval does not work, the reason being that the
PokerEval class is not seen by the caller. Syntax such as "from pokereval import PokerEval"
does not work unless the pokereval.py (which defines the PokerEval class) is renamed to __init__.py.
dos> rename pokereval.py __init__.py
3. Prepare the additional packaging files
dos>cd desktop
dos>cd pypokereval138-installer-win32-py265-fpdb
3.1/ setup.py
-------------
dos> edit setup.py
Include the following python code:
#==================================================
from distutils.core import setup
filelist = ["utils/*", "_pokereval_2_6.pyd"]
setup(name = "pokereval",
version = "138",
description = "pypokereval installer (unofficial)",
author = "project fpdb",
author_email = "Fpdb-main@lists.sourceforge.net",
url = "fpdb.sourceforge.net",
packages = ['pokereval'],
package_data = {'pokereval' : filelist },
long_description = """An unofficial installer for pypokereval v138, win32, python v2.6.5
pokereval official project page is at http://www.pokersource.info/"""
)
#==================================================
3.2 / review directory tree
---------------------------
The following structure should now exist.
pypokereval138-installer-win32-py265-fpdb
|--setup.py
|--pokereval
|--_pokereval_2_6.pyd
|--__init__.py
|--utils
|--test.py
3.3 Build
---------
Navigate to the desktop/pypokereval138-installer-win32-py265-fpdb directory
dos>c:\Python26\python.exe setup.py bdist_wininst --plat-name=win32 --user-access-control auto
3.4 Complete
------------
The executable file pokereval-138.win32.exe will be in the newly-created dist folder.
3.5 Install and test
--------------------
Double click to install
Navigate to c:\python26\lib\site-packages\pokereval\test
execute dos>c:\Python26\python.exe test.py
Output should scroll down the screen
