I’m trying to get the code action of organize imports to work with
before-save-hook. Specifically for go-mode.
I’ve been searching around and found a couple of issues later linking to a
solution similar to this:
(defun sami/eglot-organize-imports ()
(call-interactively 'eglot-code-action-organize-imports))
(defun sami/before-saving-go ()
(add-hook 'before-save-hook #'eglot-format-buffer -10 t)
(add-hook 'before-save-hook #'sami/eglot-organize-imports nil t))
(add-hook 'go-mode-hook #'sami/before-saving-go)
Problem seems to be, running the function eglot-code-actions and selecting
Organize imports works fine, but running the stand-alone function of
eglot-code-action-organize-imports does not yield anything.
Test case:
Open emacs with emacs -q for an empty config
(require 'go-mode)
(require 'eglot)
(add-hook 'go-mode-hook #'eglot-ensure)
In any go file, add something like fmt.Println(“hello”) should import the
package fmt automatically, deleting or commenting the line does not delete the
imported package fmt. eglot-code-action-organize-imports does not delete the
imported package fmt. Running the function eglot-code-actions and selecting
Organize imports DOES delete the package fmt from imports.
Here is the client-request and server-response.

Single difference between the usage of eglot-code-action-organize-imports and
not is
