A simple Lua filter to implement a manual citation command in pandoc-citeproc.
pandoc-citeproc is an amazing tool, but it sometimes produces wrong results for styles that use "Ibid." to shorten immediately repeating citations, i.e., "Ibid." occurs when it clearly shouldn't---e.g., when both bibliographic footnotes and discursive footnotes are used.
This
Bla bla. [@doe]
Bla bla. ^[Bla Bla.]
Bla bla. [@doe]
May lead to:
Bla bla. ^[Doe]
Bla bla. ^[Bla Bla.]
Bla bla. ^[Ibid.]
The "Ibid." in the third footnotes is obviously wrong.
In the absence of an official solution, pandoc's capabilities to use Lua filters provide an easy way---hackish, but efficient---to remedy this situation: You just have to add a fake citation, which will cause the next citation to be a normal citation (position="subsequent" in CSL parlor), and then use a filter to remove all citations with that particular id. This filter assumes that all such manual/fake citations have the id mancite.
This
Bla bla. [@doe]
Bla bla. ^[Bla Bla. @mancite]
Bla bla. [@doe]
Will correctly lead to:
Bla bla. ^[Doe.]
Bla bla. ^[Bla Bla.]
Bla bla. ^[Doe.]
Obviously, this can also be used to mix automatic and manual citations---e.g. when citing classical texts that currently can't be cited properly with CSL.
Usage is simple:
pandoc input.md -o output.html --csl=chicago-note-bibliography.csl -F pandoc-citeproc -L pandoc-mancite-lua
Just be sure to have the filters in the correct order: pandoc-citeproc must produce the correct citations before we remove the fake citations with -L pandoc-mancite-lua.
