AW: Custom readers and writer paths

[<denis.maier-NSENcxR/0n0@public.gmane.org>]

Yes please. Not Luarocks, at least unless someone can show an easy way to install it on Windows?

Probably better not to change the interface in this way.

Maybe treating these like filters is the most sensible/least
surprising thing to do.

IMO the most sensible. That way you can just clone readers/writers off GitHub without authors needing to go through the hassle of setting up a Lua rock. Having to do that will likely discourage people from publishing their code at all. Also of course templates, filters, defaults all work that way already. I have my data dir in my dropbox directory and symlink it in ~/.local/share, or rclone it on my Android devices (via Termux) where dropbox isn't a regular storage directory.


  Should we have readers/ and writers/
subdirectories of user data?  Or custom-readers/ custom-writers/ ?

Since they are already subdirectories of the dedicated pandoc data directory `readers/` and `writers/` should suffice. Seven characters less to type for each compared to `custom-*`.
