pandoc-displaymath2equation 0.0.0.1

Automatically number display-math equations in pandoc.

pandoc-displaymath2equations

Replace blocks of displaymath with the equation environment, and enable links to labeled equations.

This is a very simple filter. For a solution with all the bells and whistles use the (now seemingly unmaintained) pandoc-eqnos.

Usage

Install the pandoc-displaymath2equation package from PyPI, and add pandoc-displaymath2equation to your filters.

python -m pip install pandoc-displaymath2equation
pandoc --filter pandoc-displaymath2equation path/to/file.md -o file.pdf

Display Math Conversion

Content that would usually generate output like this:

\[
1 + 1 = 2
\]

will instead generate a block like this:

\begin{equation}
1 + 1 = 2
\end{equation}

Referencing Labelled Equations

To reference an equation labeled id, use a string of the form (eq:id). This will be replaced with \eqref{id}.

To label an equation, just use \label{id} in the display math block.

$$
E = mc^2 \label{important}
$$

This can be referenced in the text by using (eq:important).

Development

Source-code goes into displaymath2equation/, tests go into tst/. Code style should conform to PEP-8, and commit messages should follow the conventional commits spec.

Dependencies

Dependencies for development can be installed from requirements-dev.txt.

New dependencies should go into pyproject.toml. If code in displaymath2equation/ depends on them, they go into [project.dependencies], otherwise into an environment in [project.optional-dependencies], most likely dev.

If dependencies are added, requirements.txt and requirements-dev.txt should be regenerated. This can be done with make requirements.txt and make requirements-dev.txt respectively.

Testing

Having tests is nice. Even though the test we have is a little sparse, it's better than no test.

Docs

Documentation is nice, but doesn't exist yet. Once it does, it goes into docs.

TODOs

Possible future features that would be nice to have:

• syntax for determining the text/mark/number rendered next to the equation
• logic to deal with split/align environments
