Both Eclipse support + LSP with a single project [message #1768583]

Hello,

As we have many clients in many languages, we would like to take benefit of LSP to provide support for a specific file format.
But meanwhile we would like to be able to reuse the generated EMF model and validation mechanisms provided by Xtext out of the box in our Eclipse-based workbench. Is there a way to combine the two in an efficient way?
Is it possible for example to generate the Xtext projects for Eclipse and then use them (apart the *.ui one) for LSP (or the opposite) ?

yes and no,
you need to create some stuff manually

see https://github.com/eclipse/xtext-core/pull/390 for an inspiration

Thanks for the link! I follow the modifications proposed and ended up with a myDsl-ls.jar which is about 13MB, so it seems it includes all required stuff.
Any advice on how I can test if this JAR does the job actually?

If I can bring my2c, I think that the patch proposed on GitHub would be very useful for next Xtext releases :)

simply include it e.g. into a vscode or lsp4e with some gluecode?

Yes indeed it was obvious. I'll check some tutorials on lsp4e.
Thanks for your support.
