Add a flowchart environnement and its listof

[cedounet]

So we can more easily access those flowcharts from pdf and website, rather than looking in the crowded list of figures.

[hendricius]

For some reason they are not shown in the websiten editio

I could remove the list for now on the website?

[cedounet]

That is the easy "fix"...

• Do they show up in ebook?
• Do they show up in html?

Is the file book.loc (list of charts...) created?

[hendricius]

Good point. The CI doesn't run trying to make the ebook version. This seems to be broken too. Got this error when running make bake

:/ Let me have a look.

[cedounet]

Yeah that is something wrong with make4ht/tex4ebook

FWIW local builds work on my debian machine.

Our website issue is related to the .loc file being empty.

[cedounet]

Some more debug info the file book.4ct has loc, lof and lot infos..

My google-fu is failing me right now.

Maybe I can reach out to Michal?

Was planning to Google some more and if not do a MWE before reaching out.

[cedounet]

OK here my MWE if you could confirm it "works" (i.e. fails) for you too: `\documentclass{scrbook} \DeclareNewTOC[ type=flowchart,% types=flowcharts,% , float, name=Flowchart,% listname = {List of Flowcharts} ]{loc} \setuptoc{loc}{chapteratlist}

\begin{document} \begin{flowchart}[!htb] \caption{A flowchart} \end{flowchart}

\begin{figure}[!htb] \caption{A figure} \end{figure} \listofflowcharts \listoffigures

\end{document}`

If i do lualatex mwe.tex then cat mwe.loc I get: \contentsline {flowchart}{\numberline {1}{\ignorespaces A flowchart}}{1}{}% \providecommand \tocbasic@end@toc@file {}\tocbasic@end@toc@file and the pdf is as expected

If I do make4ht --lua -a debug mwe.tex then cat mwe.loc I get an empty file: \providecommand \tocbasic@end@toc@file {}\tocbasic@end@toc@file

[hendricius]

@cedounet great test. Can confirm - I get the same error.

[cedounet]

raised https://github.com/michal-h21/tex4ebook/issues/114

[cedounet]

Updated with michal's comments. @hendricius please have a look if that works (reverted your workaround). My ruby install is flaky right now.

[hendricius]

@cedounet thank you!!!

For some reason after trying - I still don't see the list of tables in the navigation bar on the right. However - the file is generated. I will add a workaround for this for now. I will merge the PR and create a followup PR. Side note - could you maybe directly create your branches on this repo? Then I can push to your PRs and/or you can push to mine. Thank you!
