Hi, Are dependencies taken into account inside PyPI records? I mean both build dependencies and run dependencies. If yes where can I find more info? How do setuptools manage it, how can I access this info? Ciao Vincenzo ___________________________________ Yahoo! Mail: gratis 1GB per i messaggi e allegati da 10MB http://mail.yahoo.it

No.

Neither.

Setuptools lets you declare this information in the setup script; see the setuptools.txt file for details. The "egg_info" command writes the data to a file, that is then read by other commands and also put into the built egg's metadata. This information isn't something really suitable for PyPI, because the setup script is allowed to compute the information dynamically. (Some dependencies might apply only to a particular platform, for example.)

Is there a a way(API) to interact with this information? My goal would be creating a database of correspondences between setuptools/PyPI(one day) dependency and debian package names. The software I am coding could be used by other packaging systems(rpm?) too. To create a package of a python module (immagine an egg inside a deb or rpm) one could just use setuptools and my code. But I need to resolve dependencies: this is why I'll create a database of correspondences. Ciao Vincenzo

The "requires()" method of pkg_resources.Distribution objects lets you obtain a sequence of pkg_resources.Requirement objects for a given physical distribution. It can also be used to obtain information about optional requirements. I'm in the process of creating a manual for pkg_resources that explains how to use many of these things; it's pkg_resources.txt in the setuptools CVS, but so far its information is still very sparse.
