Odd problems with undefined string abbrevations in the entry buffer

[Knusper]

In the current version of ebib (installed from melpa) I have a problem of entries not being completely displayed in the entry buffer. The corresponding error message is always: ebib-db-get-string: [Ebib] @String abbreviation 'XYZ’ does not exist, and 'XYZ' is often related to the month field

For example, in the following (created with https://www.doi2bib.org/bib/10.3758/BF03201412)

@article{Dunlap1986,
  doi = {10.3758/bf03201412},
  url = {https://doi.org/10.3758/bf03201412},
  year = {1986},
  month = sep,
  publisher = {Springer Science and Business Media {LLC}},
  volume = {18},
  number = {5},
  pages = {469--471},
  author = {William P. Dunlap and N. Clayton Silver},
  title = {Confidence intervals and standard errors for ratios of normal variables},
  journal = {Behavior Research Methods,  Instruments,  {\&} Computers}
}

I only get the fields author, title, journal, year, volume, number, and pages displayed. Similar results I get for all bibtex exports from the ads database, because also here the month field is formatted like this.

As a workaround I now created string abbreviations for all months, but to me this is rather odd behavior.

I also attach two screenshots from the entry buffer for different entry, the first is with and the second is without the string abbreviation for January defined:

Thanks for making ebib, it is an important tool in my workflow!

Are you absolutely sure you have the latest version from Melpa? This seems to be the same issues #242, which was fixed by commit https://github.com/joostkremers/ebib/commit/714931a9aeeb430e9fc412fbb372b9b1264b947b. Your test entry above (Dunlap1986) displays fine for me.

Another workaround would be do unset the option ebib-expand-strings, but that shouldn't really be necessary...

[Knusper]

I am using version - 20220430.2219 -- this is the lates version in melpa and the entry does not display correct for me. I also get the message: ebib-db-get-string: [Ebib] @String abbreviation ‘sep’ does not exist. The mentioned option helps to get the desired behavior. (One thing maybe worth mentioning is, that I use a slightly older emacs 26.1)

[joostkremers]

This is strange indeed. I have the same version installed from Melpa on my work machine and it works fine.

Could you delete Ebib, restart Emacs and then reinstall Ebib? Sometimes when upgrading a package you end up with a mix of the old and the new version. And in case you downloaded the Ebib source somewhere for a manual installation, make sure Emacs doesn't read from there.

The fact that you're using Emacs 26 should not make a difference. If it did, the error would be different.

If reinstalling Ebib doesn't help, could you check out the source code for the function ebib--expand-string? The first line after the doc string should read (condition-case err.

[Knusper]

No - I tried this -- very strange. Everything also got re-compiled and its definitely the version that is loaded (i.e., I see stuff like Compiling /home/ehere/.emacs.d/elpa/ebib-20220430.2219/ebib-utils.el...done). I also confirm the (condition-case err beginning of the function. Here is the full debug output:

[Hugo-Heagren]

I know this will sound patronising, but are you sure the string is defined in the first place? Looking at the stack trace, I can see definitions for strings for all the other months ("oct", "nov", etc.), but not "sep". Does the behaviour change if you use a different month?

[Knusper]

Of course I removed the string definition for September for testing. That is the point of my bug report here...

[joostkremers]

The point of the commit I mentioned above was to make sure Ebib would handle missing @String abbrevs gracefully. And that seems to work fine for me, but not for @Knusper , and I have no idea why.

I'll take a closer look at the backtrace next week. No time this weekend. 🙂

[Knusper]

Thanks - and I will try with a clean emacs and just ebib to rule out wierd stuff from my complex configuration.

[Knusper]

OK. I tested it with a super clean emacs (I even created a new user on my system) - the problem still persists. I even tried using emacs -Q for the new user, no luck...

[joostkremers]

Well, this is a complete mystery to me. If I run with-emacs.sh and install Ebib from Melpa, then open a test .bib file and yank the entry above, it works fine. The month field is displayed as sep with an asterisk before it and the rest of the entry is shown.

[Knusper]

I only get this behavior if I set ebib-expand-strings to nil. Although on my work laptop I have emacs 26.1, I have a secondary machine with a newer debian and emacs 27.1 ... But you say, that this error can not be due to an older emacsen?

(Thanks for the pointer to with-emacs.sh, I will use this in the future for testing, but I am very confident that the emacs I used for testing was as vanilla as it gets)
