Pandoc 3.2.1 introduced new LaTex macro \pandocbounded

[sonic-martin]

Explain the problem.

Pandoc introduced in release 3.2.1 new LaTex macro \pandocbounded which custom templates needs to provide:

LaTeX writer:

New method for ensuring images don’t overflow (#9660). Previously we relied on graphicx internals and made global changes to Gin to force images to be resized if they exceed textwidth. This approach is brittle and caused problems with \includesvg (see #9660). The new approach uses a new macro \pandocbounded that is now defined in the LaTeX template. (Thanks here to Falk Hanisch in mrpiggi/svg#60.) The LaTeX writer has been changed to enclose \includegraphics and \includesvg commands in this macro when they don’t explicitly specify a width or height. In addition, the writer now adds keepaspectratio to the \includegraphics or \includesvg options if height is specified without width, or vice versa. Previously, this was set in the preamble as a global option. Users should attend to the following compatibility issues:
If custom templates are used with the new LaTeX writer, they will have to be updated to include the new \pandocbounded macro, or an error will be raised because of the undefined macro.

Bump - I am stuck on on pandoc 3.2 because I use eisvogel extensively (thanks for the awesomeness BTW)

[ingcsmoreno]

Hi, did you find any workarounds in the meantime? Facing this right now.

[iandol]

Add the code changes yourself, the diff is quite small (see my post above).

[iandol]

Here is my modified eisvogel template that works with Pandoc 3.2.1 (but note I made other changes to support academic metadata etc.):

https://github.com/iandol/dotpandoc/blob/master/templates/eisvogel.latex#L375

changes around line 375 -- iandol/dotpandoc@e51c754#diff-7cbc217435a06b6e85d604d450361df236dbad23dba7b6c12daec404e82f1d8e

I did it myself as well, however, I think it would be better to incorporate them into the repository. I will work up a PR later today.

#392

[sonic-martin]

I looked into the build process of the docker container images, and when your PR #392 would be merged, then in the next build it would be included in the pandoc docker files as well.

See https://github.com/pandoc/dockerfiles/blob/8ba91aaf8b81b44351044f706d557b97ad39470d/alpine/Dockerfile#L184

[jvsteiner]

I think the next line, with the version number will need to be updated though.

[siddjellali]

up, appreciate

[chdemko]

See #192

Thank you @iandol for pointing out the little modification and all for working on this awesome template, it produces PDFs over my expectation, well done.

add default defintion of pandocbounded to my pdf template, everything goes well:

\newcommand{\pandocbounded}[1]{#1}

Hope this info helps.

I have the same error

Error producing PDF. ! Undefined control sequence.

Since I work with the pandoc/extra docker image I cannot modify latex templates. Anything else I can do to fix the problem in my setting?

Based on the pandoc/extra container image I built an own image adding the eisvogel.tex file from #392.

FROM pandoc/extra:3.4.0
COPY eisvogel.latex /usr/local/share/pandoc/templates

But see #392, the maintainer of the Eisvogel template will shortly release a new fixed version.

This issue should be fixed in version 2.5.0. Thank you @jvsteiner for providing a Pull Request.
