need guidance on state-of-the-art for "entry points"
by Doug Hellmann April 25, 2012

April 25, 2012

Dear Fellowship, I am starting a new project which will be heavily extensible using plugins defined in other people's packages over which I have little or no control. I was planning to use setuptools entry points to manage the plugin discovery, since it has worked so well for virtualenvwrapper. However, in the process of searching for current documentation to reference in the project documentation, I got lost and confused about what is currently supported and what is deprecated. Can someone tell me the currently approved way to work with a modern version of entry points? Should I continue to use distribute/setuptools as before? Should I move to distutils2 and some new metadata in the setup.cfg file? Should I be using Tarek's "extensions" package? If so, how do I tell distutils2 to run the registration code during installation? Thanks, Doug

setuptools feature: tag_git_description like tag_svn_revision
by Jasper van den Bosch April 22, 2012

April 22, 2012

Hello all, Might it be an idea to have an option like 'tag_git_description' similar to tag_svn_revision? A possible implementation could use git describe; such as suggested by Douglas Creager in this gist: https://gist.github.com/300803. I am currently using this for my packages, but it might be nice to integrate it into setuptools. Jasper van den Bosch

version_info
by Rob Healey April 22, 2012

April 22, 2012

Greetings: Could anyone tell me why distutils and distutils2 do NOT have available 'version_info'? I have to use '__version__' to get their version information ... I know that Distutils2 is certainly not close to being production ready, but I am just curious? -- Sincerely yours, Rob G. Healey

Greetings: This is my introductory email in writing for the first time! Of course, I am very new to DistUtils and creating my first setup.py file. I have a helper in creating this first setup.py file, but he only knows more than I do... We are stuck on this problem, and I was hoping to see if we could get some help??? Here is what is happening: [Frog@PouncingAliens geps0065]$ python setup.py sdist running sdist running check Merging translations into data/gramps.desktop. Merging translations into data/gramps.xml.

Installing subpackages under common superpackage
by Otto Maddox April 17, 2012

April 17, 2012

Hi, I have a Python project which follows a client-server architecture. It is natural to develop it as two different projects and in two different source distributions, myproject-server.tar.gz and myproject-client.tar.gz. Neither package depends on the other, but because they are part of a larger, overarching project, I want install each of them so that they appear as subpackages (myproject.server and myproject.client) under a common superpackage (myproject). I am looking for the cleanest and most correct way to do this using distutils and setup.py, so that I can end up with a structure like this: site-packages/myproject site-packages/myproject/__init__.py site-packages/myproject/server/__init__.py site-packages/myproject/server/file1.py site-packages/myproject/server/file2.py site-packages/myproject/client/__init__.py site-packages/myproject/client/file3.py site-packages/myproject/client/file4.py and so that any of the following commands (and their standard variations) work: import myproject import myproject.server import myproject.client Is there a way to write distutils/setup.py to do this? I have tried something like packages = ["myproject", "myproject.client"] in the client's setup.py and packages = ["myproject", "myproject.server"] in the server's setup.py. This kind of works, but it feels wrong because the second package which gets installed will overwrite files from the first -- for example, there is no clean way to install myproject/__init__.py. I can't imagine that I'm the first person to want to address this use case. What would be the best way of doing this? Finally, does anybody have any examples of other projects which do a similar thing? Thanks. -- http://www.fastmail.fm - Email service worth paying for. Try it for free

Installation
by vikash agrawal April 17, 2012

April 17, 2012

hi Everyone, - I am using Python 2.7, so how do I install pysetup. though when I install distutils1.0a3 I do see distutils module in my interactive session but I dont see any pysetup being installed - Also, I had previously come in contact with merwok and I would be applying in GSoC this year under PSF for distutils2 project (as I believe PSF will be under GSoC and distutils will surely be accepted), so I am writing to seek help on what all things should be my target, and how do I move ahead. - Currently, I am trying to work on the ]issue 12944 but due to certain constraints things are not geared up, though I hope they would soon be :) - Please guide me and drop-in all your suggestions Regards Vikash Agrawal -- sent via HTC Sensation

types of files...
by Rob Healey April 17, 2012

April 17, 2012

Greetings All: With the help of others and myself, we are moving Gramps[1] from an autotools system to Distutils packaging... I know that Autotools/ makefiles can handle these types of files, but I need to know if it is possible to even a way to handle? a) *.in b) *.keys c) *.xml d) man files with Distutils/ Distutils2? I need to be able to merge different language translations into these files... -- Sincerely yours, Rob G. Healey

pip on windows: life without eggs ok?
by Reinout van Rees April 17, 2012

April 17, 2012

Hi, I keep forgetting in discussions that pip doesn't support eggs. Their main usecase is installing binary python eggs on windows, I'd say. I use linux and OSX myself, so my windows experience is limited. Question: is pip's compile-from-source character a problem on windows? Does everyone use a clicky-click .exe installer for binary packages instead of pip? Is easy_install still more popular? Note, I'm not talking about installing pure python packages, but more stuff like mapnik, pil, matplotlib and psycopg2: packages that have C bindings. I'm asking because I'm writing a Django book and I don't want to get clobbered for advising pip when it won't install a mysql or postgres binding without major work. So I'd love some feedback from windows users! (I'm mostly using buildout myself, but I'm only describing that near the end of my book).
