Yes - I had to do the same for a font called Venetian 301 for which I found
these 4 files:
FilenameName as it appears to MacOS
--
Venetian301BT-Roman.otf Venetian 301 Regular
Venetian301BT-Italic.otfVenetian 301 Italic
Venetian301BT-Bold.otf Venetian 301 Bold
venetian-301-demi-bt.ttfVenetian Dm BT Demi
They each had the fi and fl ligatures, but at different character positions
depending on which file, and they weren't recognised by default. So I used the
following code to add them (and add en and em dash substitution as well).
%% start
\startluacode
fonts.handlers.otf.addfeature {
name = "v1",-- these character substitutions will be applied to
venetian-301-demi-bt
type = "ligature",
data = {
[0xF001] = { "f", "i" },
[0xF002] = { "f", "l" },
}
}
fonts.handlers.otf.addfeature {
name = "v2",-- these character substitutions will be applied to
Venetian301BT
type = "ligature",
data = {
[0xFB01] = { "f", "i" },
[0xFB02] = { "f", "l" },
}
}
fonts.handlers.otf.addfeature {
name = "v3",-- these character substitutions will be applied to both
type = "ligature",
data = {
[0x2013] = { "-", "-" }, -- en dash
[0x2014] = { "-", "-", "-" }, -- em dash
}
}
\stopluacode
\definefontfeature [venetian-301-demi-ligatures] [v1=yes,v3=yes]
\definefontfeature [venetian-301-BT-ligatures] [v2=yes,v3=yes]
\starttypescript [serif] [myBookFont]
\definefontsynonym [Serif] [file:venetian-301-demi-bt]
[features=venetian-301-demi-ligatures]
\definefontsynonym [SerifBold] [file:Venetian301BT-Bold]
[features=venetian-301-BT-ligatures]
\definefontsynonym [SerifItalic] [file:Venetian301BT-Italic]
[features=venetian-301-BT-ligatures]
\stoptypescript
%% end
Note that the names v1, v2 and v3 are entirely arbitrary. Also, the
\starttypescript section sets the font features to be just those I've defined -
potentially losing whatever 'default' would provide. But since the font doesn't
seem to have a lot of features in the first place I've so far not noticed any
problems. I'm sure a real expert could tell you how to retain 'default' and add
the ligatures, if needed.

Re: [NTG-context] How to setup a headertext in a doublesided document in a cld?
Hi Wolfgang,
Thanks for your respons!
Tonight I prepared a simplified version of the issue. It appears, that the
header as I set it up in my previous mail works correclty on odd and even
pages. However the struggle is, that after setting up the header on a odd page,
there follows a table which is split over two pages. Now on the even page there
is no header. So the question is how to convince cld to setup the header when
the table is split ….
I attach my “minimal” example, which shows the problem.
Kind regards

Re: [NTG-context] the system not working on Linux 32 with Context-lmtx
Hi, I had/have a very similar problem on FreeBSD with TeXLive 2021, with the same context.lua not found message, which I posted about a while ago. I “resolved” it by setting TEXMF to point to my texmf-dist directory, in my case /usr/local/share/texmf-dist. It would be nice for it to work without setting TEXMF. Without setting TEXMF, running "mtxrun —generate” guesses a little differently, then attempts to scan all of /usr, and then fails when parts have no read permission. I suspect it is working when you are in /usr/share/texmf-dist because the “collapsepath” function in mtxrun is collapsing “/../..” from /usr/bin to “.” instead of “/“. (Which seems like a bug, but I’m not sure.) If I run “TEXMF=/usr/local/share/texmf-dist context file.tex” things run correctly, and a ~/.texlive2021 directory is created. Running “TEXMF=/usr/local/shared/texmf-dist mtxrun —generate” runs without error but also doesn’t generate a ~/.texlive2021 directory. The real problem seems to be that mtxrun doesn’t deal well with the filesystem layout case of “/top-level/bin/mtxrun” and “/top-level/share/texmf-dist”.
