Perhaps URW Type 1 fonts need installing? --8<---------------cut here---------------end--------------->8--- Naturally searching for the URW fonts in guix didn't yield anything other than some texlive packages so I ended up writing a definition for it. It turned out to be unnecessary as I later found out 'font-ghostscript' provides just that. (an issue of discoverability perhaps?) Nonetheless my newly written package (which should be “merged” into the definition of 'font-ghostscript' with a better description and perhaps a rename) is an update of what font-ghostscript provides and should work just the same, in theory. (spoilers: it doesn't) Intrigued by this difference and after some doc reading and several arcane commands thrown in desperation, I've distilled them to this: With the existing font-ghostscript package: --8<---------------cut here---------------start------------->8--- $ guix shell -C font-ghostscript fontconfig [env]$ fc-match 'Nimbus Sans L' n019003l.pfb: "Nimbus Sans L" "Regular" --8<---------------cut here---------------end--------------->8--- With the new font-urw-base35 package (definition below): --8<---------------cut here---------------start------------->8--- $ ~/src/guix/pre-inst-env guix shell -C font-urw-base35 fontconfig [env]$ fc-match 'Nimbus Sans L' DejaVuSans.ttf: "DejaVu Sans" "Book" --8<---------------cut here---------------end--------------->8--- The source of the font-urw-base35 has a file for fontconfig at 'fontconfig/urw-fallback-backwards.conf' that contains this: --8<---------------cut here---------------start------------->8--- … Nimbus Sans L Nimbus Sans … --8<---------------cut here---------------end--------------->8--- So unless I misunderstood the fontconfig documentation and the comment, 'fc-match' should have found the newer Nimbus Sans, not DejaVu Sans. What gives?
