Check serialization order of fields with alias

[tobiasdiez]

Need to double check, but just had a changelog where journaltitle and date were moved to the end of the bibtex entry.

Any sort oder defined?

Might be a side effect of my recent changes in #5392 ?

For me it looks like it's working like expected:
Output for bibtex mode:

@Article{key,
  author       = {Author Name},
  title        = {Title},
  journal      = {journal},
  year         = {2015},
  date         = {2015-10-16},
  journaltitle = {JournalTitle},
}

Output for biblatex mode:

@Article{key,
  author       = {Author Name1},
  title        = {Title},
  journaltitle = {JournalTitle},
  date         = {2019-10-16},
  journal      = {journal},
  year         = {2015},
}

But as journaltitle is not defined for a "bibtex" entry, it is one of the "optional" field that is placed after the last required field "year". I also quickly cross-checked with a jar from May this year that I still had, and the behavior was the same at that time.

So the required fields are not supposed to be ordered alphabetically? I.e. author > date > journaltitle > title > year?

[matthiasgeiger]

Okay... Now I'm a bit confused...
After checking the code I saw that it should be sorted alphabetically, and therefore I wanted to check again from source and there I now get another output...

However, using the jar from May the output is as above.

Bibtex:

@Article{key,
  author       = {Author Name},
  journal      = {journal},
  title        = {Title},
  year         = {2015},
  date         = {2019-10-16},
  journaltitle = {JournalTitle},
  timestamp    = {2019-10-12},
}

Biblatex:

@Article{key,
  author       = {Author Name},
  date         = {2019-10-16},
  journaltitle = {JournalTitle},
  title        = {Title},
  journal      = {journal},
  timestamp    = {2019-10-12},
  year         = {2015},
}

Checking the history I guess the new behavior was introduced with #5148 - but atm I don't have really time to investigate this deeply.

//edit: @tobiasdiez you already wrote it there: "All fields are now properly sorted alphabetically (in the subgroups of required/optional fields) when the entry is written to the bib file."

Not sure whether we have test cases for that in https://github.com/JabRef/jabref/tree/master/src/test/resources/testbib.

It works as expected in the latest dev version and I added a test to make sure it stays like this: 9fd49bc
