G. @ 2023-08-11 16:34 UTC (permalink / raw) To: Org-Mode Mailing List Hi, I'm trying to figure out why I'm getting consistent failures using org-bibtex-yank. This appears to be identical to the problem posted here: https://stackoverflow.com/questions/31174281/org-bibtex-yank-fails-with-wrong-type-argument-stringp-nil On my system I am using a fresh Ubuntu 23.04 VM with the following emacs and org-mode build info: GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.37, cairo version 1.16.0) of 2023-08-11 Org mode version 9.7-pre (release_9.6.7-652-gcfea24 @ /home/test/org-mode/lisp/) My backtrace is very similar to that posted in the stackoverflow thread: Debugger entered--Lisp error: (wrong-type-argument stringp nil) looking-at(nil) bibtex-parse-entry() org-bibtex-read() org-bibtex-yank() funcall-interactively(org-bibtex-yank) call-interactively(org-bibtex-yank record nil) command-execute(org-bibtex-yank record) execute-extended-command(nil "org-bibtex-yank" nil) funcall-interactively(execute-extended-command nil "org-bibtex-yank" nil) call-interactively(execute-extended-command nil nil) command-execute(execute-extended-command) My steps to reproduce, with this as my init.el file: (add-to-list 'load-path "~/org-mode/lisp") (require 'org-loaddefs) 1. Open test.org in emacs. 2. Copy a bibtex entry in Firefox, for example this entry from Google Scholar: @article{dominik2004org, title={Org Mode Manual}, author={Dominik, Carsten}, year={2004} } 3. In the org file call M-x org-bibtex-yank. After that I experience the failure above 100% of the time. Attempts to troubleshoot: One of the comments in the stackoverflow thread mentioned that a reason this could have failed was that the variable "bibtex-dialect" wasn't set. C-h v confirms it was set in my case (to "BibTeX"), but the problem was still present. I added a line in my init.el file "(setq bibtex-dialect 'biblatex)" just to double check and the problem was still present. As described in the same comment, with my original 2 line init.el file above, 1. simply opening a new file "dummy.bib" (doing nothing with it), 2. then opening "test.org", 3. copying a bibtex entry in Firefox, 4. calling org-bibtex-yank caused org-bibtex-yank to correctly function. I did not need to call bibtex-set-dialect as the comment described. ^ permalink raw reply [flat|nested] 7+ messages in thread

This appears to be identical to the problem posted here: On further investigation I have pinpointed the precise error as referenced by the comment in the Stackoverflow thread. One of the nested function calls stemming from org-bibtex-yank is to bibtex-parse-entry in bibtex.el, and that in turn attempts to make use of the internal variable bibtex-entry-maybe-empty-head. That variable, among others, has documentation that they are nil until initialized by bibtex-set-dialect, which sets a number of other internal variables along with bibtex-dialect. That default nil value bubbles up to cause the error I am experiencing. The solution in my original email of opening a dummy.bib file works because it calls bibtex-mode and that calls bibtex-set-dialect. Adding the following two lines to my init fixes the error in my case: (require 'bibtex)(bibtex-set-dialect 'biblatex nil) where the first line seems to be necessary in my barebones case because bibtex isn't yet loaded, and the second line sets my dialect of choice (biblatex) and sets the internal variables for bibtex globally (nil), not locally (t). Given the disconnect between the error and the solution (as I understand it at least), and the absence of this necessity in the documentation (I have read through at least ol-bibtex.el), perhaps a small mention of this in the documentation in ol-bibtex.el is in order, and I can submit a patch for review?
