Yes, and I think we should stick to that for software packages, with the
already-documented exceptions of ‘perl-’ and ‘python-’.

Now, I think a good reason to add an exception for fonts is that it
would make it easier to search for them: a software package can be
searched by keyword quite reasonably (with ‘guix package --search’ &
co.), but this is not the case for a font.  Being able to type ‘guix
package -A ^font’ (say) is convenient.

Furthermore, unlike software packages, what matters here is the actual
name of the font or font collection, not the “system name” or “tarball
name.”

All good points, indeed.

I’m not completely sure we can come up with a strict algorithm for the
naming scheme that we will not want to change two weeks later.  ;-)

Here’s a possible answer to the above questions, informally:

  • Use ‘font-FOUNDRY-FAMILY’ or ‘font-FAMILY’ or
    ‘font-FOUNDRY-COLLECTION’ or ‘font-COLLECTION’ as the name.

    Examples: ‘font-bitstream-vera’, ‘font-liberation’, ‘font-unifont’.

  • Use ‘font-.*-FORMAT’ only when there happens to be separate packages
    for separate formats.  FORMAT would be the format short name, like
    ‘ttf’, ‘otf’, ‘type1’.

WDYT, fellow nitpickers?  :-)

IMO the goal should be to find something convenient for users.
Sometimes, maybe, there will be several valid choices for the package
name, but that’s fine, I think.
