OpenIDE : how to embed a code editor

[Eclesia]

Hello,

For work we often make desktop applications and at some point we made a basic syntax highlight editor for Java, Lua, CQL, javascript ... and others.

But we need to go further by providing code completion and syntax errors.

So I've checked LSP and the openide text api https://bits.netbeans.org/28/javadoc/org-openide-text/org/openide/text/doc-files/api.html.

But how to link all this together is out of my reach, everything I read is thigtly linked to netbeans RCP. I haven't found a standalone component.

Has anyone made a basic starting point example ? Something with a basic jframe and a text editor component ? Or tips on how to proceed ?

That would really help.

Thanks
