svn in virtualenv

I had some issues having svn in my virtual env - because it is created with the --no-site-packages (as it is the default).
What to do?
From the local python, this script will print out the commands for you:

python - << EOF
from os.path import dirname, join
import svn
dist_packages_dir = dirname(dirname(svn.__file__))
print 'cp -r', ' '.join(
  [join(dist_packages_dir, lib) 
    for lib in ['svn', 'libsvn']]),\
  "yourvirtualenvssitepackagesdir"
EOF

And replace yourvirtualenvssitepackagesdir with the site packages dir of your virtualenv

Python package structure

I always forgot what should be - the project structure - the contents of setup.py Basically it is just a duplication of The Hitchhiker's Guide to Packaging v1.0 documentation/Creating a Package

TowelStuff/
    bin/
    CHANGES.txt
    docs/
    LICENSE.txt
    MANIFEST.in
    README.txt
    setup.py
    towelstuff/
        __init__.py
        location.py
        utils.py
        test/
            __init__.py
            test_location.py
            test_utils.py

And your setup.py should look like this:

from setuptools import setup

setup(
    name="TowelStuff",
    version="0.1",
    packages=["towelstuff"],
    install_requires=["nose"]
    )

The other question: What should the subversion structure look like? I looked the Trac guys, to see how they do:

http://svn.edgewall.org/repos/trac/trunk/
  ...
  trac
  setup.py
  ...

So I will use the same setup.

Specify ssh port for subversion in IDEA

Say you have an ssh server listening on the port 2222. You can edit yout personal config file, located at

~/.subersion/config

but IDEA won't pick that up. Use the global config file instead:

$ grep -B1 222 /etc/subversion/config

[tunnels]
sshtunnel = ssh -p 2222

And now you can do things like:

svn ls svn+sshtunnel://HOSTNAME/repolocation
