[0.9] Python Ext Builder

[trbs]

Announcing the Python JSB Builder 0.9

Download Python Builder here

The python builder has it's own google hosted project, so that people's suggestions can be incorporated, at http://code.google.com/p/extjs-py-builder/

Notes / Futures:

If your Python installation doesn't have them already, you'll need to install elementtree or cElementTree. If you cannot install elementree system-wide you must set the PYTHONPATH environment variable so that Python can still find the package where ever it's installed.

The script runs on any Python version starting from 2.3. It should also run on Windows but that's not tested or supported. It's designed to be run on Unix style machines like: MacOSX, Linux, *BSD and Solaris. Since Python is installed on many Unix systems by default it should run flawlessly on almost any webserver.

If you have administrative rights on the system and you want the build process to be very fast, you can install Python's just-in-time compiler called Psyco. This speeds up execution time (mostly jsmin) by more then 10 times.

It can use various styles of (aggressive) minimization strategies. Like: jsmin, shrinksafe,
a packer (packing is compression, and for production it's much better to use gzip then packers!!!!) and very soon yui-compressor support.

If you have issues, find bugs, feature requests, please use the issue tracker and post in this thread.

To get this up and running with Python 2.5.2 I had to change the import statement.

From:

 from elementtree.ElementTree import ElementTree as ET

To:

 from xml.etree.ElementTree import ElementTree as ET

I checkout ExtJS from http://extjs-public.googlecode.com/svn/extjs-3.x
And launch build_ext_packages.py like:
build_ext_packages.py -CSJP "C:\Work\JS\extjs-3.x"
And I've got: "Target directory is not a ExtJS svn checkout directory"

C:\Work\JS\extjs-3.x IS my SVN checkout root directory

The python builder doesn't work with the new JSON "makefile" format. See http://extjs.com/forum/showthread.ph...828#post351828

I just noticed that you don't have a real SVN version. http://extjs-public.googlecode.com/svn/extjs-3.x does not mirror the Ext SVN. It only includes the released versions (the ZIP files you can download on this site) and has a different directory structure. If you want to build new versions off this, use http://extjs-public.googlecode.com/s...s-3.x/release/ as root directory.

Hi trbs,

do you have any plans to update py-builder to use new *.jsb2 project files of Ext 3.x branch?

extjs-3.x is just a directory. SVN path for it is http://code.extjs.com/svn/ext/trunk
