When a font is first used with lualatex
, luaotfload
does some magic to produce font cache files.
For large fonts (e.g., Noto Sans CJK) this can take a lot of time and a lot of memory.
I have an old computer (5 year old MacBook air with 4GB RAM) running Linux with a 4GB swap partition. The initial cache generation of this font can take more than 15 min and render my computer unusable. Sometimes I just run out of memory and the process is killed.
Let's say I want to use the font as such:
documentclassarticle
usepackagefontspec
setmainfont[Script=CJK,Language=Chinese Simplified]Noto Sans CJK SC
begindocument
中文
enddocument
What is the least resource intensive way and/or fastest way to generate the required cache files?
At the moment, I quit everything (even X11) and run lualatex
from the console, but it still takes a long time, and quitting everything is a bit of a pain.

You can do as proposed in section 9.2.1 “Trimming fonts“ in Fonts out of ConTeXt and remove all the glyph names in the font.
Adapted to LaTeX and your example:
documentclassarticle
usepackagefontspec,luacode
beginluacode*
fonts.handlers.otf.readers.registerextender
name = "remove names from Noto Sans CJK SC",
action = function(fontdata)
if string.match(fontdata.metadata.fullname, "Noto Sans CJK SC") then
texio.write_nl("Trimming font " .. fontdata.metadata.fullname)
for k, v in next, fontdata.descriptions do
v.name = nil
end
end
end
endluacode*
setmainfont[Script=CJK,Language=Chinese Simplified]Noto Sans CJK SC
begindocument
中文
enddocument
Can this solution be problematic in some cases?
– Paul Gaborit
Mar 16 at 8:21
@PaulGaborit Yes, anything that wants to access glyphs by name won't work. In ConTeXt there isgetnamedglyphdirect
which will break. I don't think there is anything like this in LaTeX. Also those name lookups are not very efficient.
– Henri Menke
Mar 16 at 8:28
Well, I did manage to successfully generate cache files for Source Han Serif (regular, bold). Chromium was killed to compensate, used up all my RAM, and took half an hour! But it did work. Without yourlua
code I didn't manage to complete the compile without it being killed. So that's something.
