Upgrade MyST-NB to get glue:math directive to work

[martinlarsalbert]

Describe the bug

context

The glue:math directive is not working in JupyterBook as seen in the documentation:
https://jupyterbook.org/en/stable/content/executable/output-insert.html#the-glue-math-directive
...where the equation has no number ( ).

This seems to be a bug that has been corrected in later versions of MyST-NB:
https://myst-nb.readthedocs.io/en/latest/render/glue.html#the-glue-math-directive

But JupyterBook is not compatible with this newer version of MyST-NB as it seems.
The newer MyST-NB works for html generation but not with latex builder.

expectation

bug

$ jupyter-book build mybook --builder latex

File "E:\dev\wPCC_pipeline\venv\lib\site-packages\sphinx_jupyterbook_latex\transforms.py", line 433, in apply
from myst_nb.nodes import CellInputNode, CellOutputNode
ModuleNotFoundError: No module named 'myst_nb.nodes'

problem
Apparantly "myst_nb.nodes" does no longer exist.

I removed the failing part as a dirty fix that works for me now, as I don't have any code blocks.
But I suspect that is not a good solution for all.

   class CodeBlockTransforms(SphinxPostTransform):
    """Handling any post transforms needed for code cells."""

    default_priority = 999

    def apply(self):
        if isinstance(self.env.app.builder, builders.latex.LaTeXBuilder):
            """Wrapping myst_nb code cell nodes with nodes of this extension."""
            pass
            #from myst_nb.nodes import CellInputNode, CellOutputNode
            #
            #for node in self.document.traverse(CellOutputNode):
            #    celloutput = CellOutput()
            #    celloutput.append(node.deepcopy())
            #    node.replace_self(celloutput)
            #
            #for node in self.document.traverse(CellInputNode):
            #    cellinput = CellInput()
            #    cellinput.append(node.deepcopy())
            #    node.replace_self(cellinput)

thanks for reporting this issue @martinlarsalbert

@AakashGfude this will be a blocker for upgrading jupyter-book to support the latest myst-nb so we should try and prioritise this one.

[AakashGfude]

sure thing @mmcky will take this up as a priority.

[mforbes]

Can the requirements be updated to pin myst-nb to an appropriate version so that pip install brings in the correct version if installed with sphinx-jupyterbook-latex? Currently the warning comes when running Sphinx, requiring people to pin the versions themselves.

[AakashGfude]

@mforbes which myst-nb version is currently throwing warning? I was assuming sphinx-jupyterbook-latex works with all versions between >=0.13 to <=0.16, as pinned https://github.com/executablebooks/sphinx-jupyterbook-latex/blob/master/setup.cfg#L34

[mforbes]

Ah. I did not notice that myst was an extra, pip install "sphinx-jupyterbook-latex[myst]" works. Please change my request to simply update the docs to mention the myst extra.

Thank you @mforbes for bringing this up. I have created an issue #110 and will create a PR.
