announce not working for me
by Kevin Dangoor 31 Aug '05

31 Aug '05

I'm doing something wrong, and it's probably very obvious... from distutils.core import setup from distutils.core import Command class FooBar(Command): description = "foo. no! Bar!" user_options = [] def initialize_options(self): pass def finalize_options(self): pass def run(self): print "am I here?" self.announce("Run, I say!") setup( cmdclass = { "foobar" : FooBar } ) Running "python setup.py foobar" prints the "am I here?" line, but not the "Run, I say!" line. This is true even with the -v flag. *Should* this work? Kevin

svn tagging setuptools command
by Ian Bicking 30 Aug '05

30 Aug '05

So, I made my first setuptools command; I don't know where it really belongs, but I've dumped it here for now: http://svn.pythonpaste.org/Paste/Deploy/trunk/paste/deploy/tag.py Then you do "python setup.py tag --version=0.3" to copy the trunk to a tag (in a normally-laid-out subversion repository) and adjust setup.py and setup.cfg. It's not particularly robust, but I thought I'd note that it's there. I can vaguely imagine other svn based setup.py commands for project management; maybe a few thrown together could become a package. -- Ian Bicking / ianb(a)colorstudy.com / http://blog.ianbicking.org

listening for EntryPoints
by Kevin Dangoor 30 Aug '05

30 Aug '05

I'm planning to use the EntryPoint facility for plugins in my application, and I was just thinking about what it would take to load a new plugin. My best guess is that, right now, it would take a restart... which is not bad, but not ideal either. In order to dynamically add a plugin at runtime, it seems like I would need 1) a way to get a new egg loaded 2) a notification to go out to the parts of the code that care about the entry points for a particular name or group. Does anyone else care about being able to add plugins without a restart, or is it just me? Kevin

setuptools deps
by Vincenzo Di Massa 28 Aug '05

28 Aug '05

Hello, As you know I'm developing easy-deb using setuptools. I need a way to query a module dependencies, but I don't know how to achieve this. I need to know dependencies because when I install an egg into a package I don't want the dependencies to go into the same package. So I detect if setup.py uses setuptools (grep setuptools setup.py) and then: if the module uses setuptools: I call setup.py bdist_egg -d dest/pkg/dir else: I call easy_install.py -d dest/pkg/dir . # in the setup.py containing dir Is there a way to tell easy_install "don't install dependencies but tell me what they are". Better, I would like to be able to detect dependencies from inside python. Thank you Ciao Vincenzo ___________________________________ Yahoo!

PythonModulePackaging

I have just put on pipy the first version of easy-deb: a tool to make source debs out of standard python modules. I would really like to thank everyone who helped me. A special thank to "Phillip J. Eby" for setuptools. I someone woul like to test it and tell if how it is working... I will be really HAPPY :-) Vincenzo I attach the same docs: ========== =easy-deb= ========== FEATURES ======== * Packages python modules * from source distribution files * from urls * from PyPI records * can package it self * handles dependencies * intstalls modules into eggs (from setuptools) * can activate or deactivate an installed egg (add or remove from sys.path) * handles a database of dependencies ======================= =easy_deb instructions= ======================= SYNOPSIS ======== easy-deb: ^^^^^^^^^^ Type $ easy-deb -h for usage and options synopsis: usage: easy-deb [options] (pypi-modulename | archive-file-name| url) options: -h, --help show this help message and exit -v VERSIONS, --python-versions=VERSIONS Coma separated list of python versions to package for. E.g.: -v 2.3,2.4 -d DEPS, --debian-deps=DEPS Standard debian dependency string. %v is replaced with python version -b BDEPS, --debian-build-deps=BDEPS Standard debian dependency string. %v is replaced with python version -f FIND_LINKS, --find-links=FIND_LINKS Additionnal links to scan -D DEST_DIR, --dest-dir=DEST_DIR Distribution downloaded into file -c, --common-dir Install to commond dir from where tree linking is done -a, --arch-dep Build arch dep packages -u, --update-database Update the database of python modules options update-pypi: ^^^^^^^^^^^^^ Type $ update-pypi -h for usage and options synopsis: usage: update-pypi [options] (module-name | show | updatew) options: -h, --help show this help message and exit -a, --add Add egg to sys.path -r, --remove Add egg to sys.path USAGE ===== easy-deb: this tool will create a debian source package into a deb-pkg-<modulename> directory. To compile the source package use the standard debian tools (debuild or "fakeroot debian/rules binary") update-pypi: this script is used to enable and disable installed egg (you can enable/disable all eggs ing the removing the All package). Enabled eggs are on sys.path, disabled eggs must be pkg_resource.require() before you can import from them. EXAMPLE ======= To install module "graph": $ easy-deb -v2.4 graph -D /tmp/ $ cd /tmp/deb-pkg-graph0.4/graph-0.4 $ fakeroot debian/rules binary $ sudo dpkg -i ../*.deb $ update-pypi -a graph

Well, it's broken in a couple ways. One is that a setuptools egg for py2.2 doesn't exist. But anyway, I've attached a patch that fixes two problems I've encountered in ez_setup.py -- distutils.log, and tempfile.mkdtemp (doing crude clones of both). I don't know what issues setuptools itself might still have. This doesn't make it functional, but I guess it's closer. -- Ian Bicking / ianb(a)colorstudy.com / http://blog.ianbicking.org

Installing data files
by Antti Korvenoja 24 Aug '05

24 Aug '05

Hello! I would like to ask for advice how to install data files that is used by the modules or scripts in a package. I need to provide the path where some template image files are installed, also in the case that the package is not installed under sys.prefix. Studying the documents did not provide me an answer and searching previous discussions about this issue left me with an impression that this might not be supported in current distutils. Is it possible to extract somehow within distutils whether an alternate installation location was specified or do I need to resort to parsing the commandline in my setup.py? Any advice is highly appreciated, Antti Korvenoja

Opening question
by Scott Mayham 23 Aug '05

23 Aug '05

Well, I just now joined this SIG. I'm an abject Python newbie. My role is that of Installation developer for various Windows products produced by my company. Therein lies my need for help. We are rushing out the door, a new version of one of our main products. Part of what's new about this release is that some parts of it are written in Python (2.4, I think). These parts also use some bits for the PyWin package. I have been chartered with exploring whether we can bundle the Python Windows installer (the MSI that the link on the "downloads" page points to) along with our product, and whether it (the Python installer) can be launched as a silent sub-install, in much the same way as we presently launch the Microsoft MSXML4.msi. As usual, the pointy-haired boss doesn't understand that the install developer doesn't (yet) know squat about Python. I've just gotta get it installed so it can support our product. I know, Disutils is supposed to make this unnecessary, but (I'm told) we use some stuff in PyWin which uses some stuff in Python which is not normally packaged that way. If I've been told wrong, tell me what I need to know/do in order to package up our spiffy new written-in-Python software. Any help, hints, even sympathy will be greatly appreciated. Regards, T.

setuptools: Plugins
by Ian Bicking 22 Aug '05

22 Aug '05

I'm looking for some advice on using setuptools/eggs/entry_points for plugins. Specifically, how do I find distributions tht provide the entry points I'm interested in? For instance, can I find all the distributions that provide "paste.script_command" entry points? Or does there need to be some way for these distributions to tell my package they exist? -- Ian Bicking / ianb(a)colorstudy.com / http://blog.ianbicking.org
