Hello,
I need to include lua-modules from different directories, but package.path
does not seem to work:
\startbuffer[test]
bla = nil
\stopbuffer
\savebuffer[test][../mytest.lua]
\starttext
\startluacode
package.path = "../?.lua;;"
require("mytest")
\stopluacode
\stoptext
Error message:
! LuaTeX error <main ctx instance>:3: module 'mytest' not found:
TIA for any help!
Cheer, Peter

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) stack traceback: [C]: in function 'gsub' /opt/tex/texmf-local/tex/context/base/l-file.lua:133: in function 'split_path' /opt/tex/texmf-local/tex/context/base/data-lua.lua:36: in function 'clibpaths' /opt/tex/texmf-local/tex/context/base/data-lua.lua:97: in function </opt/tex/texmf-local/tex/context/base/data-lua.lua:79> [C]: in function 'require' <main ctx instance>:2: in main chunk. }inserted text> ...equire('testmodule') -- fails \dodostartluacode ...d \directlua \zerocount {#1}} l.5 \stopluacode 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').
