Extra capabilities

Besides LSP official capabilities, clojure-lsp has some extra features:

Refactorings

It should be possible to introduce most of the refactorings here

More details

Calling executeCommand with the following commands and additional args will notify the client with applyEdit. All commands expect the first three args to be [document-uri, line, column] (eg ["file:///home/snoe/file.clj", 13, 11])

done	command	args	notes
√	add-import-to-namespace	[document-uri, line, column, import-name]
√	add-missing-libspec
√	clean-ns
√	cycle-coll
√	cycle-privacy
√	expand-let
√	extract-function	[document-uri, line, column, function-name]
√	inline-symbol
√	introduce-let	[document-uri, line, column, binding-name]
√	move-to-let	[document-uri, line, column, binding-name]
√	thread-first
√	thread-first-all
√	thread-last
√	thread-last-all
√	unwind-all
√	unwind-thread
√	resolve-macro-as	[document-uri, line, column, resolved-full-symbol kondo-config-path]
√	create-test

See Vim client section for an example.

Emacs provides all those refactorings via lsp-mode with the lsp-clojure- prefix.

Other clients might provide a higher level interface to workspace/executeCommand you need to pass the path, line and column numbers.

Custom methods

clojure-lsp has some custom LSP methods that doesn't follow the protocol but aggregate value as a clojure IDE:

command	args	notes
clojure/serverInfo/raw		Use to retrieve from server the server configuration information
clojure/serverInfo/log		Use to log to user the server configuration information
clojure/cursorInfo/log	[document-uri, line, column]	Use to log to user the debugging information for the symbol at cursor
clojure/clojuredocs/raw	[symbol-name, symbol-ns]	Use to retreive any Clojuredocs entry. Will return null if no entry found.
