Installing filters - best practice for file locations?

[AndyClifton]

I've written a filter for pandoc that I would like to use in multiple different file conversions.

Currently I place the filter in the same directory as the source files, and then call pandoc using something like this:

$> pandoc ...  --filter filters/name_of_filter

where filters is a subdirectory.

I'd like to just maintain a single copy of my filters.

Q: Does pandoc have a default location where it checks for filters where I could deploy my filter? I guess I can choose this myself by giving an absolute path to the filter, but is there a best practice for this?

From the manual:

In order of preference, pandoc will look for filters in
1. a specified full or relative path,
2. $DATADIR/filters where $DATADIR is the user data directory (see --data-dir, above).

An addition, for executable (non-Lua) filters:

3. $PATH (executable only).
