Re: requiring other lua files from parent directories from within filters

[Bastien DUMONT <bastien.dumont-VwIFZPTo/vqsTnJN9+BGXg@public.gmane.org>]

The argument of require() is not a path, but a string that is passed to a template. The template is composed of semi-colon separated strings where ? is stands for the argument of require() (after all . have been replaced with /). For instance, if the template is:

  ./?.lua;/usr/local/share/lua/5.4/?.lua

and you pass 'library.library' to it, Lua will search in ./library/library.lua and /usr/local/share/lua/5.4/library/library.lua

The path is controlled by environment variables. In your case, if all loaded files are in the ../library directory, I would advise to call your script with:

  LUA_PATH='../library/?.lua' pandoc-lua script.lua

and to write in inner/script.lua:

  library = require("library")

Of course, you can also set the path to '../?.lua;./?.lua' if you want to be able to load files from the current directory and to write explicitely the path to library.lua as library.library!
