ConTeXt setup in TeX Live

[Bruno Voisin]

The following problem arose earlier today on the lucida list.

Having installed the Lucida OpenType fonts in TEXMFLOCAL, having installed the files

https://github.com/contextgarden/context/blob/main/tex/context/fonts/mkiv/lucida-math.lfg
https://github.com/contextgarden/context/blob/main/tex/context/fonts/mkiv/lucida-text.lfg
https://github.com/contextgarden/context/blob/main/tex/context/fonts/mkiv/type-imp-lucida.mkiv

also in TEXMFLOCAL, having initialized the ConTeXt setup in TeX Live 2024 with

	mtxrun --generate
	mtxrun --script fonts --reload

then when applying context to a file containing

	\setupbodyfont[lucida]

	\starttext
	This is a test
	\stoptext

no Lucida fonts are used, only Latin Modern.

Looking closer,

	mtxrun --script fonts --list --all --pattern='*lucida*'

finds nothing. Actually, inspecting the cache

	TEXMFVAR/luametatex-cache/context/a86c089b384a3076dc514ba966a1fac9/fonts/data/names.tma

it appears none of the fonts from TEXMFLOCAL are listed there.

On the other hand, installing ConTeXt in ~/context using the install script from

	https://wiki.contextgarden.net/Installation

installing the Lucida fonts into ~/context/tex/texmf-fonts/, setting PATH (on an Apple Silicon Mac) such that ~/context/tex/texmf-osx-arm64/bin comes at the beginning, and running again

	mtxrun --generate
	mtxrun --script fonts --reload

then afterwards

% mtxrun --script fonts --list --all --pattern='*lucida*'

and the test file above uses Lucida Bright OT as expected.

Is ConTeXt, as packaged in TeX Live 2024, supposed to look for fonts inside TEXMFLOCAL? Based on /usr/local/texlive/2024/texmf-dist/web2c/texmfcnf.lua, which contains

         -- TEXMF           = "{$TEXMFHOME,!!$TEXMFPROJECT,!!$TEXMFFONTS,!!$TEXMFLOCAL,!!$TEXMFMODULES,!!$TEXMFCONTEXT,!!$TEXMFSYSTEM,!!$TEXMFMAIN}",
            OPENTYPEFONTS   = ".;$TEXMF/fonts/{data,opentype}//;$OSFONTDIR",

it would seem yes. But apparently not.

I'm no ConTeXt user myself, I just looked at this to help the user who reported the problem, so I really can't say. I looked for an invocation of mtxrun, similar to "kpsewhich --show-path=.otf", which would say where ConTeXt looks for OpenType fonts, but I could not find any.
