Bug#663357: uscan: Please support scanning git repositories for tags

[Antonio Ospite]

Package: devscripts
Version: 2.13.4
Followup-For: Bug #663357

Hi,

I check tags from gitweb with a watch file like this one[1]:
-----------------------------------------------------------------------
version=3

opts=downloadurlmangle=s/shortlog\/refs\/tags\/(v[\d\.]+)/snapshot\/$1.tar.gz/,\
filenamemangle=s/.*v([\d\.]+)$/tweeper-$1.tar.gz/ \
  http://git.ao2.it/tweeper.git/tags  ^.*v([\d\.]+)
-----------------------------------------------------------------------

The example relies on clean URLs being enabled but you can get the idea:
  1. parse the /tags page and look for vRELEASE
  2. build the link to the archive: from /shortlog/refs/tags/vRELEASE
     to /snapshot/vRELEASE.tar.gz
  3. save the vRELEASE.tar.gz archive as PACKAGE-RELEASE.tar.gz

The regexes can change depending on the structure of the release tags,
I use a 'v' prefix like in vX.Y.Z and end up with PACKAGE-X.Y.Z.tar.gz
as the result.

If you find the info useful, feel free to add it to the uscan manpage.

Ciao,
   Antonio
