I think that there are a lot of things that could be done to make PyPi a
place where users can find *high wuality* packages and one that makes it
desirerably for developers to have their packages listed there.
Unfortunately comments *on the package main page* is not among them.
I think the PyPi/Python developers should consider the following points:
* PyPi is the de facto *official* repository of third party packages
that form the "enhanced" stdlib
* I as a developer chose PyPi to be the *official* website of my
projects and I want to have control over this website.
I could name a plethora of things I would do to enhance PyPi and here
are some ideas:
Right now the package consists of a single page and all information is
cramped in there. I would suggest having a "tab-style" bar containing
* Package description/Home (default)
Right now I have to place a link to the documentation I uploaded
to PyPi in the package description myself? Why? Include that
automatically on the package site as soon as it is uploaded and
tell the developers about that feature!
* Issue tracker (either hosted on PyPi or somewhere else)
* Downloads (for different releases)
Place comments on a different page, give developers the possibilty
to enable this feature and react to comments. Maybe include a way
to rate comments and those with a higher rating will bubble up
Automatic Package testing
What I really like on PyPi is that my packages are tested automatically
with Cheesecake and the order of packages when searching is determined
by this rating. This gives a huge incentive to work on the package
quality, which is a great thing IMHO. Ratings by users could influence
this ranking as well...
I would take this idea even further.
All packages should be tested automatically and *REJECTED* if they don't
meet certain quality criteria. PyPi should become a place where high
quality packages can be found, not a dump for every single "Hello World"
Debian will run lintian (a Debian package checker) automatically against
newly uploaded packages and reject those that don't meet a basic set of
Tests could reject packages that:
* do not install/uninstall cleanly
* miss important files (README, CHANGELOG, .. )
This could leverage platform specific information as in: If it is
a *nix package and includes scripts, it should have man pages for
* rate poorly on automatic tests (pep8, cheesecake, pylint, ...)
* are not GPG signed
* have not specified a license
I admit that this makes PyPi a much stricter place and suggest that
sections are introduced that define different rules for inclusion (like
Debian's stable, testing, unstable - main, contrib, non-free). There
could be sections like this:
* main - manually checked packages of high quality
This would comprise packages of a high enough quality to be deemed
acceptable in the stdlib
* tested - packages not in main that rank high on automatic tests
* junk (better name required)
Users could then decide which parts they want pip to retrieve packages
from. We could even encourage github, bitbucket, sourceforge, ... to
provide ways to automatically query their repositories from pip so they
could be included in pip's "sources.list" and used to install
dev-versions, packages of por quality.
*IF* Python plans to develop a fully fledged platform agnostic package
manager for Python programs/libraries it would be wise to learn from the
solutions people came up with until now (aptitude, yum, pkg_add, emerge,
