Hi Christoph,
I am not sure if this will help, but this is the mailing list for lsp4e, you may have more luck with the lsp4j mailing list? There are devs who have made language servers based on lsp4j that may not be working on lsp4e, so not subscribed to this list.
HTH,
Jonah
The problem is that currently there is no language-server available for
gherking/cucumber (or I haven't found it yet).
gherking itself provides an own parser for java so lsp4j seems a good
choice. But based on the lack of information how to build an own
language-server from scratch its a bit hard to getting started.
What I got so far is that I can start the languageserver and connect it
to the generic editor. I'm also getting an event in the server code when
something is edited, but now I'm a bit stuck about the basics maybe e.g.
how lsp4j is supposed to handle the state of the document, how give
"feedback" to the editor, what capabilities do I need for basic
operation and so on.
So I hoped there would be a simple example demonstrating such basic
usecase :-)
