Is it possible to grab the source-code from a Google Code repository (hg) using wget or curl?
Else using Python?
Thanks for all suggestions
FYI: I'm on a shared WebFaction host, so can't install hg
You should be able to use Google's HTTP interface to their repositories.
The easiest way would be to grab a raw file link:

And then dissect the URL.
You can then download the files with curl, or mirror the whole repository (or, at least the current revision) with wget. For example
wget --mirror https://typo3scripts.googlecode.com/svn/trunk/
