Can't run either \printbibliography or \csl:reference.

Both give me this same error:

I've been trying with different .bib and .csl files as well...

Line 106 is the gsub on subsequentAuthorSubstitute (however inherited). (EDIT: fixed my reference after a check to the code)
Which CSL file(s) are you using?

[Omikhleia]

Actually, MLA and Chicago have subsequent-author-substitute (which are the ones I mostly used, or derivatives of thereof)... but not a bunch of other styles that don't do author substitution. And CSL 1.0.2 implies the field is optional indeed ("If set..." -- I visibly overlooked it ^^)

So the code lacks a little condition check there indeed. Should be easy to fix, just an "if" around that block. ^^

[Omikhleia]

(Still, let me know which style you primarily target, and I'll do some extra tests upon my return from X-mas vacations)

[jodros]

Now, after a new attempt, I've found that with this one it at least generates the PDF, even though the command \printbibliography still doesn't work, while \csl:reference does

Those that don't work are (for now):

• Ipea ABNT
• UFAL ABNT

[Omikhleia]

Thanks. I'll test those styles upon my return from vacations (on my 2700+ reference biblio), just to ensure there are no further unnoticed issues that the one mentioned above. If this is urgent, of course, feel free to experiment. I did test various MLA and Chicago derivatives, and a few European journals, but one never knows, a train can hide another :).

[Omikhleia]

BTW, Ipea ABNT does have a subsequent-author-substitute attribute in the <bibliography> element, so if it fails, it might be another problem. Don't hesitate checking the logs and report it separately if confirmed to be on a different element...

[Omikhleia]

(UFAL ABNT doesn't have the subsequent-author-substitute attribute, so is clearly failing here due at least to it)

[Omikhleia]

@jodros Problem confirmed to be the missing condition on subsequent-author-substitute in UNEAL-ABNT (which you called UFAL above, but the link is to UNEAL), and fixed in #2204

Then:

• On my side, UNEAL-ABNT, ABNT-IPEA and UFES-ABNT now all generate a bibliography (= all of my 2800+ entries from my Tolkien bibliography), so if the two others failed for you, we'll need a deeper analysis (ex. finding an offending entry) in a dedicated issue...
• When I say they all generate a bibliography, I don't mean it's necessarily correct however:
  • Some macros are interpreted as present while they should apparently be considered as absent. An example is the "translator" macro, which generates a "Tradução " even in the absence of translator(s) afterwards. Re-reading the CSL 1.0.2 specification, however, the only place where content suppression is clearly mentioned is on cs:group (acting as implicit conditional), but there's no such element here... It's still unclear to me where the intended behavior is defined...
  • (EDIT) There's an interesting problem with links (with URL, DOI, etc.) and here again the CSL specification is somewhat obscure and I'd even say rather inconsistent (conflating usage for affixes...)
