Warn if \problemtitle differs from problem.settings.name[language]

[thorehusfeldt]

When problem.en.tex contains

\problemname{Hello Gaia!}

but problem.yaml contains

name:
  en: Hello World!

there currently is no warning. BAPC instead expects the author to write

\problemname{\problemyamlname}

but there can be reasons to avoid that macro, typically due to other tooling. (In particular, it is one of the few details that prevents a BAPC-compatible problem package from being problemtools/verifyproblem-ed.)

There is extensive parsing of TeX-code already being done in bt constraints, but the above check could be done quite easily and catch 99% of cases.

A more aggressive solution would be to actually edit problem.en.tex after bt new_problem and bt rename_problem.

Sounds reasonable to add a warning/log for this indeed.

I think the most common usecase for this is when the latex name includes additional markup that we don't want to expose in the yaml. But it's probably fine to just warn for these cases anyway since accidental mismatches are worse than a few extra warnings.

We could also check if the expected string is a substring of the actual string... That would reduce the number of warnings but would also suppress the warning for some types of typos.

[thorehusfeldt]

Can you give an example? I would understand whitespace normalisation (because LaTeX is lenient about that).

[mzuenni]

It would not warn for markup like this: \texttt{IX}th Problem because IXth Problem is still a substring. On the other hand, it would no longer warn for IXth Prooblem or stuff like that...

[thorehusfeldt]

Ah, that kind of substring. Now it makes sense.

Minimal solution is now a concrete pull request, please comment there.
