Use the org.eclipse.lsp4e.languageServer
extension in plugin.xml
to define a language server (ie how to start it and connect to it) and to associate it with one or many content-types.
See multiple examples in the test.
Use the ProcessStreamConnectionProvider
if your LS is accessible as a process.
To handle LSP Commands (e.g. associated with CodeLens
messages) in the IDE, register a sub-class of org.eclipse.lsp4e.command.LSPCommandHandler
in the plugin.xml
file of your plug-in via the org.eclipse.ui.handlers
extension. The handler has to be registered for the commandId
equal to the Command.command
attribute of an LSP message. Note that client side handlers will not be triggered, if the language server is capable of executing commands of the same commandId
.
