Hello,
the attached patch adds support for a new upstream: Google Fonts via
GitHub. The `upstream_parameter` format is
`google-fonts/$font_licence/$font_name`, for example
`google-fonts/ofl/pompiere`.
Before explaining the patch I need to explain why this is needed and the
unusual way fonts on Google Fonts are "released". To start with, fonts
made available on Google Fonts lack proper release tarballs. Each font
is maintained in a subdirectory that is part of a huge git repository
hosted on GitHub (previously on Google Code).
These fonts lack also meaningful version numbers. Modifications are,
however, almost always recorded in the `FONTLOG.txt` file that is
present in most directories. In addition, not all the revisions of a
certain font are available in the git history, only the latest one is
assured to be available. For all these reasons the most reliable way to
identify a font version is the date recorded in `FONTLOG.txt`.
The modified `fakeupstream.cgi` generates a page with a list of
available versions for a given font. Unfortunately it is not possible to
link these versions to release tarballs because GitHub does not generate
tarballs for subdirectories, so the links lead to fictitious URLs.
I tested the generated page with uscan 2.15.9 and it can detects the
current and past versions of all the fonts I tested it with.
Regards,
