I have broken the back on my personal itch to want low friction markdown based citation management. I have a basic release for the curious at https://github.com/singingfish/Citeproc-Markdown - it’s a bit more than proof of concept but lacks pandoc integration until I actually write some text containing my special citation keys.
Two particularly useful things about this:
- The test file demonstrates how to get useful information out of the csl processor in a reasonably self documenting way.
There’s a tarball in the github repo that provides code that will install using existing cpan infrastructure. I won’t release it to CPAN until it’s generically testable.
The README is below:
Package for handling human readable Author/Date citations in markdown
format. Designed to be good enough for common use cases, not perfect.
Code is also a good start to a more general Zotero/Perl gateway.
Will scan a plain text document paragraph by paragraph for citations
using a human readable format to key citations. Conversion will die
without modifying the document if there are ambiguous citation keys.
Requires mozrepl (<https://addons.mozilla.org/en-us/firefox/addon/mozrepl/>) installed and running to the same Firefox, or XULRunner that your Zotero library is stored in. Other than that, and a working modern perl ( >= 5.10.0) no other extensions, firefox or otherwise are required. Examples of the format are (c|Fletcher 2003 Mapping stakeholder perceptions) (c|Law 2008 On sociology) (s|Law 2008 On sociology) The final example is to supress author (not yet implemented, but supported in the regex). The code will warn if more than one keys are found (maybe it should die ...)
1. Tests work on my local machine but not elsewhere due to citation
library differences and zotero setup.
2. Tests only work with a running
zotero and mozrepl.
3. Need to write the pandoc integration (need to
write some markdown with citations).
4. Supress author citations not yet
supported (but stubbed (s| form of citation to support this at a later
5. Consider adding compatible zot4rst citation keys.
However, this module provides the basis for having decent markdown/zotero integration without the need for intermediate files. In the final implementation I suppose there will be two different versions of the script run "markdown_cite --draft" that will keep the author cite keys untouched, and dump the references to a file, and "markdown_cite --final" that will replace them with the final CSL generated citations.

paragraph compiles as a standalone entity. If not the repl will hang
then time out.
parses the citation to author title and year hashref
Simple regex for parsing the text string. TODO. consider making a proper
parser. TODO. consider optional doi support.
Lazy accessor for the available zotero styles. Returns a hashref: key:
name val: url.
Uses instantiateCiteProc in citeproc.js to set the current style.
Takes a list of cites (c|Whatever 1999 Title fragment)(c|Someone 2002
Stuff) etc and splits into an array for further processing.
Create the bibliography after all citations have been processed.
Given an in-text citation (could be one or more ([cs]| … form
