Hi, Thank you Phillip for your help and support!
I would like to access a package metadata before it is installed:
I use the following class
####################CLASS class Easy_deb: def __init__(self,req_string): self.requirement = pkg_resources.Requirement.parse(req_string) self.index = PackageIndex() self.found = None self.dest = None self.filename = None self.source_dir = None
def download_source(self): self.index.find_packages(self.requirement) self.found=self.index.obtain(self.requirement) if self.found: self.dest='deb-pkg-'+self.found.key+self.found.version if os.path.isdir(self.dest): shutil.rmtree(self.dest) os.makedirs(self.dest) self.filename=self.index.download(self.found.location, self.dest)
def unpack(self): unpack_archive(self.filename, self.dest) setups = glob.glob(os.path.join(self.dest, '*', 'setup.py')) self.source_dir = os.path.dirname(setups[0])
def deb_src(self): debian_dir=os.path.join(self.source_dir,'debian') shutil.copytree('template',debian_dir) #file=os.path.join(debian_dir,"control") #print file sed(os.path.join(debian_dir,"control"),"%%PKGNAME%%",self.requirement.key) <------ SED LINE os.chdir(self.source_dir)
#inst_dir=os.path.join('./debian','tmp') #main(['-d']+[inst_dir,'.'])
def create(self): self.download_source() self.unpack() self.deb_src() ####################END OF CLASS
to download modules and create a deb package. I need to retrieve other metadata like description, author and license. I nned it to put it into lines like SED LINE.
Thank you again Vincenzo

The above line is redundant; obtain() will call find_packages() automatically. Also, you may not want to use obtain anyway. For what you are trying to do, I would suggest running "easy_install --editable --build_dir=somewhere requirement", because then it will handle all the details of finding and unpacking the source. The source tree will then be "somewhere/projectname" (the project name will be all-lowercase). You could use a temporary directory for "somewhere", if you like. In any case this will take care of most of the things you're doing in this code outside of the deb_src() method.

Well, you can always run the package's setup script, and in fact you will need to do so if you're working with an unbuilt source distribution. Most of the PKG-INFO metadata items can be displayed using options to setup.py, however. For example, running this in the setuptools directory:
python setup.py --name --version --author --license --url
produces this output:
setuptools 0.6a0 Phillip J. Eby PSF or ZPL http://peak.telecommunity.com/DevCenter/setuptools
Use setup.py --help to get a list of the available options.
Note that you may want to pass the name and version results through pkg_resources' safe_name() and safe_version() functions.
