Re: Jazz Chord Symbols (as new font - NOT notation font)

[Marco Baumgartner]

the output of:

\markup \roman "fi"

is in the attachment. It does not produce the ligatures - both in standard and a testing font of mine containing ligatures (otf).

In the word "leer", the letter e and r should be connected.

I stumbled over this (2015):

http://lilypond.1069038.n5.nabble.com/Broken-ligatures-in-recent-LilyPond-versions-td171760.html

It's said, that as of 2.18.2 and newer, ligatures are broken in lilypond. Doesn't seem to be the case for everybody though...

I've updatet my system, running Debian Stretch 9.9 now.

Lilypond is no longer in the standard-repository in this updated version, so I've installed the generic package "2.18.2" from lilypond.org.

That's what I'm going to test next. Unfortunately, I'm facing some installation issues. I somehow messed up the original package,

while trying to install a newer unstable version. Now I can't re-install 2.18.2 from Debian repository as it's missing. Let me figure this out. I'll let you know,

when I'm back with a running version and tested the above code.

Well, I would put my vote on the side of "should be working".  Consider
the following simple example:

%%%%
\version "2.18.2" % tested on lilybin.org
\markup \roman "fi"
%%%%

You *should* get the "fi" as a ligature in the output.  It would be good
to verify this on your system.  Then, use \override #'(font-name . "Your
custom font") and test your font.

This may have more to do with Pango than LilyPond, since it is Pango
that is the one dealing with fonts.  If there is something wrong with
how it handles OpenType ligatures, that could certainly end up affecting
what you see in LilyPond.

You can install fonts wherever your fontconfig is set up to load them. 
For instance, I have my custom fonts installed in my home directory:

   ~/.local/share/fonts

I did this as to not conflict with any font packages that are normally
written to /usr/local/share/fonts.

Unsure, but as I indicated above, I think this is on the Pango side, not
LilyPond.

If I did that, I would have more fingers pointing back at myself.  You
would not have to dig too far in the mailing list archive to find proof
of my lapses into incompetence.
