Although @tim-hub , these are experimental features of Mermaid-js-erd

[tessus]

It's possible that our Mermaid version does not even have that feature yet.

[tessus]

Yep, this was added in 8.5.0. We use 8.4.6.

You're perfectly right, tessus. This feature is added to v8.5.0 and we're using v8.4.6 . Everyone can see below in the changelog of mermaid-js Features section.

@laurent22 @coderrsid @tessus

thanks for the finding out

[tessus]

No worries, at one point we'll update Mermaid. No ETA though.

[tessus]

@laurent22 I actually tried to update mermaid, but none of the scripts updates the mermaid.js in rnInjectedJs. What am I missing?

I tried npm i in the root folder, npm run build in ElectronClient and ReactNativeClient.

Update: Never mind, I figured it out, but it actually resulted in more questions:
Why is the mermaid package in the package.json of ElectronClient and ReactNativeClient, while all where it is needed is in ReactNativeClient/lib/joplin-renderer/package.json.

Mermaid has to be updated. Upstream already fixed the issue I encountered after upgrading to 8.5.0.
So we should be good to go.

I'll submit a PR tomorrow. I'm currently not home.

[tessus]

I've updated Mermaid to 8.5.2, but the squence diagram and the gantt chart are too small. I suspect that we have previously added additional css to Joplin to fix upstream issues, but I don't know.

@laurent22 do you remember adding fixes for Mermaid upstream bugs that had something to do with the size of the mermaid images?

The problem is that new versions of Mermaid require a change from fit-content to 100% for the width. But this also results in another issue described here: https://discourse.joplinapp.org/t/upgrading-mermaid/10140/4?u=tessus
However, since Laurent changed it to 100%, we can also upgrade Mermaid....

[laurent22]

Isn't it the same issue as this one? #3097 I think the fix would be to make the graph scrollable rather than 100% width, so that we can handle graphs of any size.

[tessus]

Well, the fit-content did that, but then some of the graphs are too small. I explained this in the topic referenced.
So I think at one point you added the fit-content but now after mermaid 8.5.0 some images are too small. Going back to 100% fixes the size problem, but then the scroll issue resurfaces....

[MHoeller]

The issue is fixed, with version 1.2.x since this was a release I considered this as tested.
In case it is needed: from my perspective this issue can be closed

[tessus]

Yep, Caleb added this with the bump to Mermaid 8.x.y
