An vs a with mathematics

[tobiasdiez]

Is your feature request related to a problem? Please describe.
When using mathematical expressions, the an-vs-a check leads to suboptimal results. For example,

This is an $n$-dimensional problem.

results in a warning (although it is grammatically correct as $n$ is pronounced "an").

Describe the solution you'd like
No warning message in the above example, but a warning if "a" is used instead.

Describe alternatives you've considered

This is a known issue, see first point of https://valentjn.github.io/vscode-ltex/docs/contributing-code-issues.html#known-issues-and-limitations. It's not possible to solve this without fully parsing L^AT_EX with proper macro expansion etc. Even then, it would still be hard to decide (e.g., whether a u is really like uniform or rather like undecidable; actually, even LanguageTool warns for the correct This is a u-dimensional space.)

This is exactly what LT_EX's Ignore in this sentence feature was invented for.

I agree that is not possible to have a solution that works in all cases without a complete parsing of Latex. But it should be fairly straightforward to support the most common single-letter expressions like $n$, $N$, \( n \)$, which I guess already cover a lot of cases.

Maybe its possible to use the dummy feature and replace these expressions by some word having the same sound as the single-letter. For example, use "antic" in place of "n", so that LangugeTools sees This is a antic-dimensional problem.?

Fair enough, I thought this was about solving this in general. Thanks for the request.

Thanks a lot for the quick implementation! Much appreciated.
