Great! Can we try it? Or it's not yet in public version?
I tried out the new citeproc-enabled pandoc (from citeproc
branch), comparing it against pandoc 2.10.1 + pandoc-citeproc.
My test project was a document with about 30,000 words,
using a 132K bibtex bibliography.
In addition to pandoc-citeproc, I used a lua filter to
count words.
For pandoc 2.10.1 + pandoc-citeproc, the build (to HTML)
took 2.22s.
With the new citeproc-enabled pandoc, it took 1.03s.
By comparison, without --citeproc (skipping citation processing)
it took 0.84s. So, the overhead for citation processing is now
pretty minimal, and people should see a big speedup.
