mytest.lua is a module, so it must be loaded with require:
You cannot always replace 'require' with 'dofile', and for
this reason it is important that package.path actually works
as explained in the lua manual. (escrito had similar problems,
and other external lua modules will run into it as well).
well, package path is supported (as is cpath) so it's more a question of
why that paths fails .. maybe we need to explicitly assume ";" instead
of the platform separator (tests on my machine work ok as windows has ;
as separator)
you can test this with adding an explcit ";" to
libpaths = file.split_path(_path_,";")
in data-lua.lua
For me on linux, this change should make it work (package.path indeed
contains semicolons). However, require() is still broken:
! LuaTeX error /opt/tex/texmf-local/tex/context/base/l-file.lua:133: bad
argument #1 to 'gsub' (string expected, got nil)

Test files are attached. The definition of package.libpaths I used:
function package.libpaths()
print (_path_, package.path)
if not _path_ or package.path ~= _path_ then
_path_ = package.path
libpaths = file.split_path(_path_,';')
print (table.serialize(libpaths))
end
return libpaths
end
And it prints out:
nil
./?.lua;/usr/local/share/lua/5.1/?.lua;/usr/local/share/lua/5.1/?/init.lua;/usr/local/lib/lua/5.1/?.lua;/usr/local/lib/lua/5.1/?/init.lua
t={
"./?.lua",
"/usr/local/share/lua/5.1/?.lua",
"/usr/local/share/lua/5.1/?/init.lua",
"/usr/local/lib/lua/5.1/?.lua",
"/usr/local/lib/lua/5.1/?/init.lua",
}
But it looks like mkiv is not happy with the split path, as it goes
on trying clibpaths().
Also, I ran into another problem: if the module has the same name as the
base input file, package.libpaths is not called at all (initially the
module was called 'tryme.lua').
Best wishes,
Taco
