Diagram generation

[Serhioromano]

Chevrotain has a great built in diagram generator. All you need is to serialize parser.

const serializedGrammar = parser.getSerializedGastProductions();
const htmlText = chevrotain.createSyntaxDiagramsCode(serializedGrammar);
const outPath = path. Resolve(__dirname, "./")
fs.writeFileSync(outPath + "/generated_diagrams.html", htmlText);

Can we add options -d parameter for langium generate that could also generate that diagram to see how it actually built?

👍 I'd make this a separate command like langium syntax-diagram

Why not have it as a config parameter like for syntax highlighting?

[Serhioromano]

I like the direction of this conversation. For me it is not a critical how. Separate or parameter the fact that it is there will be much appreciated.

I thought you typically don't need that to be always up-to-date, but only when you want to debug the grammar. On the other hand, it could be useful to always generate it to include it in documentation. In that case adding this to the config makes sense.
