Store custom lua writer centrally on my machine

Store custom lua writer centrally on my machine

Hello pandocers!

I have managed to follow the description how to create the instruction how 
to write a custom writer for pandoc <https://pandoc.org/custom-writers.html>, 
say mywriter.lua. Locally, I can succesfully use it with the -t option of 
pandoc. Now, I would like to make it available globally.

Is there a central path I can store it in my machine, so that I can invoke 
pandoc with -t mywriter.lua 
<https://pandoc.org/MANUAL.html#custom-readers-and-writers> in order to use 
my custom writer, regardless from the directory I run this command?

For templates, I know I can use usr/share/pandoc/data/templates, as pandoc 
will look for templates in that directory if it could not resolve the 
reference to a template locally. Is there something similar for custom 
writers?

I have looked through the documentation and searched the internet, but I 
didn't find an answer. I also tried to guess a path. The following paths 
did *not* work:

   - /usr/share/pandoc/mywriter.lua
   - /usr/share/pandoc/data/mywriter.lua
   - /usr/share/pandoc/data/templates/mywriter.lua
   - ~/.pandoc/mywriter.lua
   - ~/.pandoc/templates/mywriter.lua

(If this is relevant, I work on an Ubuntu machine.)

If there is no such option, could it be added? I tried to understand the 
Option parsing in the source code but had to give up quite soon, because I 
don't know any Haskell.
I have also asked this question on StackOverflow 
<https://stackoverflow.com/questions/71720215/central-path-to-store-pandoc-writer>, 
but I figured, I would probably get better answers here on the list.

Thanks for your help!

Jonathan

You should be able to store all such files in ~/.local/share/pandoc. You can create subdirectories if needed. You can find more information in the manual under --data-dir.
