Python SWIG bindings help
Hello All,
I'm not sure if this question has been answered before (I could not
find anything in the mailing list archives) so please excuse me if it
has.
I was starting some work on my local SVN repository - trying to access
it via Python, similar to what ViewVC or Trac do. I followed the intro
to the API at http://jtauber.com/python_subversion_binding/ but am now
stuck at trying to figure out a way to get the directory listing for
the ROOT. All I want to know is how to get a full listing of folders
or files under a given path (for example, if my repository resides
under /opt/svn/repos, I want python to return me a list of items under
that folder). This might be trivial to do, but I have been unable to
figure it out for the past couple of days. Some help would be greatly
appreciated.
Best,
R

If you can get the info that you need from the client (like your example
above), I would definitely suggest using pysvn because its interfaces and
documentation are in much cleaner shape. [I have not used pysvn, even though
I have wanted to. But from the docs and form what I have read, it is much
easier to use than the bindings]

I have not found a good documentation resource for the SWIG bindings. You
could obviously read the C header files within the source distribution. But
it is quite complicated. Moreover, I learn faster using examples and so I
started off by looking at the two short examples in the book (
http://svnbook.red-bean.com/en/1.1/ch08s02.html) and also the
svnlook.pyfile in the distribution (in the tools/examples folder).
The subversion/bindings/swig/python/test folder also includes code from the
trac project. The code within it is a good primer on how to use the
bindings.
These examples do not replace documentation, but if you just want to
experiment with the usage of python bindings, these resources will help you
a lot.

Hari,
Thanks a lot. That does just what I wanted it to do. I had also, in
the meantime figured out how to do something similar using pysvn -
import pysvn
path = svn+ssh://rmanocha@myhost/opt/svn/repos
client = pysvn.Client()
entries = client.ls(path)
I will look into both these methods in some more detail and see which
one I would rather use. Do you have any suggestions?? One problem I
did have with using pysvn was that I have to login using my password
everytime using the above code (even though I defined a login callback
function and assigned it as per the documentation on pysvn's site).
Also, is there any source of documentation/tutorials for the python
svn SWIG bindings (I don't mind reading c header files too if someone
can just show me how to :)).
Best,
R

Here's a very very basic code that you can start with:
from svn import fs, core, repos
mypool = core.svn_pool_create(None)
myrepo = repos.open("/opt/svn/repos")
myfs = repos.fs(myrepo)
myyoung = fs.youngest_rev(myfs, None)
myroot = fs.revision_root(myfs, myyoung, None)
def entries(path):
listing = fs.dir_entries(myroot, path, mypool).values()
return [ x.name for x in listing ]
print entries("")
print entries("trunk")
# etc..
Hope this helps.
regards,
-Hari

Any suggestions here - I'm still unable to wrap my head around this problem.

Paul,
I did take a look at pysvn and from what I gathered, it was more of a
client side library. I want to work directly with the server/local
repository (again, something like viewcv or trac) instead of having to
checkout a version of the repository before being able to work with
it. Am I getting pysvn wrong here??
Thanks,
R

For what it's worth: you might take a look at pysvn. I've used both,
and found pysvn easier to work with.
