Failed to update arxiv items in existing bib files

[syrte]

When I run
adstex main.tex -o main.bib -r mylib.bib --merge-other --force-regenerate

It failed to update the following items from the existing mylib.bib file (which is exported from zotero)

@article{Simon2019,
  title = {The {{Faintest Dwarf Galaxies}}},
  language = {en},
  journal = {arXiv e-prints},
  url = {https://ui.adsabs.harvard.edu/abs/2019arXiv190105465S/abstract},
  author = {Simon, Joshua D.},
  month = jan,
  pages = {arXiv:1901.05465},
  year = {2019}
}
@article{Richings2018,
  title = {Subhalo Destruction in the {{Apostle}} and {{Auriga}} Simulations},
  language = {en},
  journal = {ArXiv e-prints},
  url = {https://ui.adsabs.harvard.edu/\#abs/arXiv:1811.12437},
  author = {Richings, Jack and Frenk, Carlos and Jenkins, Adrian and Robertson, Andrew},
  month = nov,
  pages = {arXiv:1811.12437},
  year = {2018}
}

Usually, the arxiv number should be given as eprint for ads entries. Not sure why these items are not in the standard format. I can fix it by adding the following block at the end of the function entry2bibcode.

    if "pages" in entry and entry['pages'].lower().startswith('arxiv:'):
        s = fixedAdsSearchQuery(arxiv=entry["pages"].split(':')[1], fl=["bibcode"])
        try:
            return next(s).bibcode
        except StopIteration:
            pass

I'm satisfied with my solution for now. If you feel it could be a general problem for others, you can take it into your code. Thanks.

Thanks for the report @syrte. If you have a chance to try out #17 that'd be great. I'll merge it later today.

[syrte]

Thanks for the update, it's nice to have such extensibility.

Hmm, the page here

adstex/adstex.py

Line 256 in f19cbcc

("page", "arxiv"),

should be pages. Then it works in my case.

[syrte]

BTW, a space is needed in "FOUND IN SECONDARY BIB SOURCES," -> " FOUND IN SECONDARY BIB SOURCES,"

adstex/adstex.py

Lines 406 to 410 in f19cbcc

	"{}:{} UPDATE => {}".format(
	key,
	"" if key_exists else "FOUND IN SECONDARY BIB SOURCES,",
	bibcode_new,
	)

[yymao]

Thank you for testing it out and providing solutions @syrte! Should all be fixed in #17 now.

[syrte]

And I have another question, the bib file generated by adstex always starts with

@string{june = {June}}

Is this necessary? Or just to test the bparser?

[yymao]

Ah, this is another hack for some specific bibtex generator (but I forget which). The correct way to specify the month June in bibtex should be

month={June},

or

month=jun,

But some bibtex sources use

month=june

which is not standard bibtex. This prefix fixes this.
