Mermaid JS Output Formatter

[jan-simbera]

The basic implementation of the MermaidJS formatter.

[patrickkusebauch]

I think it is somewhat better as an extension. That's why https://github.com/Dance-Engineer/deptrac-awesome/blob/main/src/OutputFormatters/MermaidJsFormatter.php exists

[dbrumann]

@patrickkusebauch I think it's fine to have this formatter in the core. I would like to replace some of the static images in the docs with the the MermaidJS-output at some point. I also have some vague ideas for features around this, e.g. extracting layers and rules from a diagram and then turning it into a depfile-template with basic formatters based on the names.

@jan-simbera The current implementation does not color a violations graph red, right?

[jan-simbera]

No, it only displays the results. No colored graph yet. Is it still considered to be added? Should I implement that additional? @gennadigennadigennadi

[gennadigennadigennadi]

Yes, it would be nice to have the same featureset as the graphiz-image has.

@jan-simbera I don't know how someone would use the current output of the formatter, it gets dump straight into the stdout. Therefor I'm asking my self, if we should also use the -o-Flag to write the output into a file?

And could you also implement a test, that verifies the current output-format?

[gennadigennadigennadi]

@jan-simbera Im okay with merging this branch, but would you also be willing to work on the php-config of the mermaidjs-formatter?
And it's also necessary to update the documentation!

[jan-simbera]

Yeah, should I create a new MR, or should I add it to this one?

What's the status of this PR?

[jan-simbera]

Documentation pending, small changes pending, I could get to finish this next week.

[gennadigennadigennadi]

Please update the git origin for development to https://github.com/qossmic/deptrac-src and reopen the PR.
Thank you very much!
