add likeC4 as another available syntax

We'd love to see likeC4 as another available syntax.

Interesting, what export format are you using?
From what I’ve read in the documentation, it’s possible to export to PNG, but it relies on Playwright to take a screenshot (which is a bit heavy). Otherwise, there are exports to other diagram formats such as mmd, Mermaid, DOT, D2, or PlantUML. It’s also possible to export to draw.io, but in all these cases the rendering will be quite different from the one provided by default in the LikeC4 interface.

You're right, likeC4 does not look like the other syntax.

In fact, it is more a large ecosystem of tools with multiple integration. I don't know if it is easy to integrate likeC4 into kroki, but I think this ecosystem really worth to have a strong look at it.

The way we are using kroki is to embed schema into markdown documentation as jpg or png files. We'd like to use likeC4 in the same way.

That said, I agree that using Playwright and a browser to generate an image is way too heavy. I also agree that using likeC4 to generate another syntax does not solve the problem to embed the image into a markdown documentation. Exporting to draw.io would not be a solution as well.

I tought that a solution would be to use the API but this API looks more like a programmatic API than an HTTP API.

I see that there is some GitHub actions that looks like an HTTP API.

As you said, the CLI only exports to png, but png is nowadays widely used.

As a conclusion, likeC4 is maybe not yet ready to be embedded into kroki, but we should keep a strong look at likeC4.
