As all files of the pgf package and all files input during a normal
latex compilation are searched this way, where is the problem when a
few more files must be find there?
My main problem with the scripts folder is that it is not meant for
a lot of lua-files like fontspec.lua or the input files of
luaotfload. If you look at the folder you find in it e.g. perl
scripts and bat-files for *external* tools like makeglossaries
called after or between a latex run. It doesn't contain files
inputed during a normal latex or plainTeX compilation. Also scripts
hasn't a substructure differencied by formats, you can't e.g. make a
hyphen.lua for latex and another one of cslatex.
The OP asked where to put "lua scripts" and naturally this
prejudices the scripts folders. But I wouldn't put too much weight
on the word "script". A tex file is a script too, I have seen people
ask "I have written a tex script. Where should I put it?". And the
answer naturally depends on the content and function of the file. A
"document-tex-file" goes to the document folder, the input of a
latex sty to tex\latex or perhaps to tex\generic, and the source of
a documentation to "doc".
Btw: With the unstable branch of luaotfload/the newest code of
context it is possible to write virtual lua fonts, which eg mix
different fonts and can be use like this
What at your opinion is a good location for these lua-files?
