tha.tagfinder

tha.tagfinder is a library for finding trunks and tags in an svn hierarchy. Including options for not descending into specific directories and so.

More details in src/tha/tagfinder/USAGE.txt .

Usage of tha.tagfinder

The goal of tha.tagfinder is to traverse though an svn structure and return tags and trunks.

Three imports are needed:

>>> from tha.tagfinder import extracter
>>> from tha.tagfinder import finder
>>> from tha.tagfinder import lister

You need a startpoint, which is either an svn url or a directory name. Our test fixture provides an svn repository:

>>> repo_url
'file://.../repo'

Give your startpoint to a lister, in this case an SvnLister, with an optional list of directory names that should be ignored:

>>> startpoint = lister.SvnLister(repo_url, ignore=['sandbox'])

Choose an extractor. Normally the BaseExtracter, but you can subclass it:

>>> info_extracter = extracter.BaseExtracter

Lastly, set up a finder with the startpoint and the extractor. Optionally pass in stop_indicators that, when found in a directory, will stop the finder from recursing in that directory:

>>> info = finder.Finder(startpoint, info_extracter,
...                      stop_indicators=[])

The main usage is to query this info object for the projects it has found:

>>> print(info.projects)
[<tha.tagfinder.extracter.BaseExtracter object at ...,
 <tha.tagfinder.extracter.BaseExtracter object at ...]

Every project object has attributes that are provided by the extracter. So subclass the extracter if you need extra attributes of your own:

>>> project = info.projects[1]
>>> project.name
'project1'
>>> project.location
'file://.../repo/project1'
>>> project.tags
['0.1', '0.2', '0.3-bugfix']
>>> project.tag_location('0.2')
'file://.../repo/project1/tags/0.2'

TODO
