Incorrect OOXML math to latex conversion

[KOLANICH]

Hello, I was transforming from docx to latex and mentioned that

1. openofficexml eqiuvalent of \hbar is not transformed correctly
2. openofficexml equivalent of \hat is not transformed correctly (transformed to \acute )
3. openofficexml equivalent of \vec is not transformed correctly (transformed to \overrightarrow)

Thanks for the report. Please give us the output of pandoc --version,
along with some specific examples with input and expected and actual
output.

here is latex source generated

\[\acute{\overrightarrow{p}} = - \mathbb{i}\overrightarrow{\nabla}\]

sorry for misinformation, it uses its own format, not MathML

[mpickering]

Thank you for your report, (2) is fixed in the development branch. Here is the output I currently get.

\hat{\overrightarrow{p}} = - \mathbb{i}\overrightarrow{\nabla}

I think we chose \overrightarrow as it stretches over long inputs, is there a reason to choose \vec?

Finally, the missing \hbar is because I mispelled amssymb, changing the defaultEnv to fix this produces the following rendering.

\hat{\overrightarrow{p}} = - \mathbb{i}\hslash\overrightarrow{\nabla}

How does that look?

[KOLANICH]

I think that it is more correct to use \hbar.

is there a reason to choose \vec

It is semantically more correct, also some TeX editors don't recognise \overrightarrow

[mpickering]

The character in your document is 210F which corresponds much better to \hslash than \hbar.

I think we could change the output to use \vec if the argument is one or two characters.

[jgm]

I'm going to leave \overrightarrow -- for \vec we'd have to know if the argument is one-character, and the logic that looks up these markers currently doesn't know that.
Other issues have now been fixed in texmath.
