That's elegant. Another way to get the value of `myDir` would be 

local myDir = pandoc.path.directory(arg[0]) 

and should also work on all platforms. It relies on pandoc's built-in 
path library and on a feature of the default lua interpreter, which 
pandoc replicates for compatibility: 
https://www.lua.org/manual/5.4/manual.html#7 


I find with pandoc 3.1.8 that while `arg` is defined for a script executed 
with `pandoc lua`, it is nil for a filter executed with `pandoc -L`. So I'm 
back to my borrowed elegant solution.
