Thanks I wish that worked. I don't know what I'm doing wrong, here's what I've got… `pandoc --version` says user data dir is `~/.local/share/pandoc` so I placed this file there as `~/.local/share/pandoc/links-with-page-number.lua` and did (just in case) `chmod +x` on it. `pandoc -o test.pdf test.html` produces a 2page pdf as expected with no footnotes. `pandoc -L links-with-page-number.lua -o test.pdf test.html` fails to produce pdf file with: ``` Error running filter links-with-page-number.lua: links-with-page-number.lua: openBinaryFile: does not exist (No such file or directory) ``` There's no typo in my script name or command invocation. Using ~/.pandoc instead of ~/.local/share/pandoc doesn't make any difference, still get that same error. Any ideas?
