Compiling Mermaid in Latex

[acasanova99]

There is any way to generate latex code from a mermaid diagram? I mean a direct way of compiling it. It would be rather useful to have one.

At the moment, I just generate an svg and add it as a picture.

Not that I'm aware of. Edit: @Kochise's https://github.com/Kochise/latex-mermaid looks pretty good to me!

It should in theory be possible to modify a package like gnuplottex so you could just write:

\begin{mermaid}
  %% your mermaid diagram here
\end{mermaid}

Then your LaTeX package could take care of calling mermaid-cli using \immediate\write18{mermaid-cli\space \inputfolder/\figname.mmd \outputfolder/\figname.pdf} to create a PDF, then import that PDF into your file.

But, to be honest, if you're doing any complicated LaTeX project, you're probably using latexmk with a custom Makefile, so in that case, it's probably just easier to add a rule to your Makefile like:

%.pdf: %.mermaid
    npx -p @mermaid-js/mermaid-cli mmdc --output $@ --input $<

Then, you can just run \includegraphics{myfile.pdf} files in your LaTeX file, and if they don't exist, if you call latexmk with the -use-make option, it should automatically generate myfile.pdf from myfile.mermaid.
