I was kinda suprised when I could not find any good sites with 3rd party modules (other than the Vaults of Parnassus, where you must host files elsewhere), so I decided to write one myself :) It is brand new and might still be buggy, but hopefully it will be usefull to some people. Feel free to join and upload any of your code. thanks
Hi,
Just yesterday, I was frustrated waiting for replies from Catelog-SIG about the possibilities of a package management system that works like Fink (fink.sf.net). Basically, the problems I see is that C extension modules aren't portable across major Python revisions and there is no easy way to maintain the installed packages in site-packages directory. My scenario is that a system admin has to maintain 50 different libraries and their dependencies...
So I've decided to write something myself... and call it 'centipyde'.
Modelled against Fink and Darwinports (darwinports.opendarwin.org) (obviously I'm a Mac user), information (in text file) are in a folder (centipyde/pkginfo/) as .info files. Each package will have a .info file which tells the system (centipyde) where to download the source tar (or zip) and how to install the package, as well as the dependecies, maintaining the installed packages etc etc. No difference from other package managers (a goal)...
It is still very rough at this moment, so please bear with me. Basically, the user will have to cvs checkout the system and just run it.
I've checked it into Sourceforge, under IB-DWB project (which is abandoned) as 'centipyde'. But for some reason, I still can't view it in ViewCVS yet. Anyway, the directory layout is
../centipyde ../centipyde/centipyde.py ../centipyde/pgkinfo ../centipyde/pgkinfo/ply15.info
ply15.info contains the following text (pretty much modelled against Fink):
package=ply15 maintainer=. dependencies=. downloadurl=http://systems.cs.uchicago.edu/ply/ply-1.5.tar.gz prebuildscript=tar zxvf ply-1.5.tar.gz sourcedir=ply-1.5 buildscript=python setup.py build installscript=sudo python setup.py install
centipyde.py is the following: =====================================================

PKGINFOPATH = 'pkginfo' INSTALL_LOG = 'install.log'
import os import string import sys
def install_package(package_name):
f = open(os.getcwd() + os.sep + PKGINFOPATH + os.sep + package_name + '.info', 'r')
install_info = {}
for line in f.readlines():
line = string.split(line, '=')
if line[1][-1] == os.linesep:
install_info[line[0]] = string.strip(line[1][:-1])
else: install_info[line[0]] = string.strip(line[1])
f.close()
print "Package Installation Information: " + str(install_info)
os.system('curl -O ' + str(install_info['downloadurl'])) preinstall = []
preinstall = string.split(install_info['prebuildscript'], ';')
for cmd in preinstall: os.system(cmd) cwd = os.getcwd()
print cwd
os.chdir(os.path.join(os.getcwd(), install_info['sourcedir']))
print os.getcwd() buildscript = []
buildscript = string.split(install_info['buildscript'], ';')
for cmd in buildscript: os.system(cmd) installscript = []
installscript = string.split(install_info['installscript'], ';')
for cmd in installscript: os.system(cmd)
if sys.argv[1] == 'install': install_package(sys.argv[2])
=====================================================
When I run "python centipyde.py install ply15", PLY1.5 gets downloaded from David Beazley's website, uncompressed and installed into the site-package as shown here:

I think there are some obvious ways that we might work together...
