Support for Mermaid.js in kaleido

coma007 commented 7 months ago

Hi all,

I added new scope that would support the rendering of Mermaid graphing library. Here is an usage example:

from kaleido.scopes.mermaid import MermaidScope

scope = MermaidScope()

graphDefinition = """
    graph LR
    A --- B
    B-->C[fa:fa-ban forbidden]
    B-->D(fa:fa-spinner);
    """

data = scope.transform(graphDefinition, format="svg", config={"theme" : "default"})
with open("figure.svg", "wb") as f:
    f.write(data)

Method scope.transform(markdown, **kwargs) accepts mermaid markdown and returns svg code in string bytes. Also, this method accepts custom configuration which is not mandatory.

What I did:

Added all the necessary files for scope pipeline (read official documentation for more).
Added support for <script type="module"> tags in repos\kaleido\cc\kaleido.cc. This can be used when scope is delivered via esm.
Moved js methods such as is-non-empty-string and is-positive-numeric to utils so that it can be used by any scope.

What needs to be done:

Add support for different versions of mermaid cdn. See Mermaid's changelog.
Add support for different image formats. For now, only svg format is available.

Hi! I'm trying to coordinate a rerelease of kaleido, I'm first working over the build system, updating the api, and moving it to modern version of chromium. Hoping to get buyin from plotly on CI.

What platform did you develop this on? Linux?

Hi, yes, I used wsl Ubuntu for the build, because I had trouble building it on Windows. I've also tried the build on PopOS Linux on my machine and it worked. Good luck !
