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.

  • @Joseph, yes xelatex has no problems of course. Although I notice something curious with xelatex. I use the true type collection font: NotoSansCJK-Regular.ttc. When I run pdffonts on the the PDF file produced by xelatex it gives: ROREZJ+NotoSansCJKjp-Regular-Identity-H. (Notice jp for Japanese instead of sc for Simplified Chinese as requested). I don't know where the error is though. I guess it xelatex could be embedding the right font from the ttc but with the wrong name.

  • As an addition to my previous comment: I'm pretty sure the output is correct even though the font reported is always the jp one. All the language specific fonts contain all glyphs and the right language seems to be automatically used by xelatex when you request a language specific font without manually specifying the Language= option of fontspec.

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.



enter image description here



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

    Mar 16 at 8:21











  • @PaulGaborit Yes, anything that wants to access glyphs by name won't work. In ConTeXt there is getnamedglyphdirect 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 your lua code I didn't manage to complete the compile without it being killed. So that's something.
