I have a lua file that I would use in many of my TeX's documents, loading it with dofile().

I thought it was ok if I simply put it in the (local) texmf tree*, but this doesn't work. Instead I have the following error message :

LuaTeX error cannot open the mycode.lua: No such file or directory

Is there any nice solution ?

  • I try to save the file in ~/Library/texmf, in ~/Library/texmf/tex, ~/Library/texmf/tex/latex and even in ~/Library/texmf/lua (I had to create the directory).

    Where precisely did you save the file? – egreg Oct 4 '11 at 13:43
  • How do you load the file? require()? dofile()? – topskip Oct 4 '11 at 13:45
  • Placing file.lua in the same folder and loading with dofile("file.lua") works, but I'd also be interested in a more general solution (especially since dofile("/path/to/file.lua") doesn't seem to work). – scallops Oct 4 '11 at 13:51
  • @scallops of course it works, but it isn't a nice and general solution at all. So we have to wait for the gurus :) – Matsaya Oct 4 '11 at 13:53

    require() should normally use kpse. E.g. require("fontspec.lua") finds fontspec.lua in tex\latex\fontspec. – Ulrike Fischer Oct 4 '11 at 14:12

dofile() expects full path (or path relative to current directory). You have to either use require() which will search TEXMF tree, or use kpse.find_file() and pass the returned path to dofile(). kpsewhich -show-path=lua should show the search path for lua files.

require() searches (TeXlive2011, LuaLaTeX) in these texmf subdirectories:

scripts/lualatex/lua/
scripts/luatex/lua
scripts/lua
scripts/lualatex
scripts/luatex
scripts
tex/lualatex
tex/latex
tex/luatex
tex/generic
tex
