Emacs JDE completion with Ido and Yasnippet
I love all kind of completion. But I don’t like JDE’s built in completion methods. I therefore wrote a little function that uses two of my favorite tools in Emacs: IDO and Yasnippet.
Put the defun in the JDE hook.
(defun jde-complete-ido ()
"Custom method completion for JDE using ido-mode and yasnippet."
(interactive)
(let ((completion-list '()) (variable-at-point (jde-parse-java-variable-at-point)))
(dolist (element (jde-complete-find-completion-for-pair variable-at-point nil) nil)
(add-to-list 'completion-list (cdr element)))
(if completion-list
(let ((choise (ido-completing-read "> " completion-list nil nil (car (cdr variable-at-point)))) (method))
(unless (string-match "^.*()$" choise)
(setq method (replace-regexp-in-string ")" "})"(replace-regexp-in-string ", " "}, ${" (replace-regexp-in-string "(" "(${" choise)))))
(delete-region (point) (re-search-backward "\\." (line-beginning-position)))
(insert ".")
(if method
(yas/expand-snippet (point) (point) method)
(insert choise)))
(message "No completions at this point"))))Eval and do C-c C-v . on a variable:
public class Test
{
public static void main(String[] args)
{
String mess = "Hello World!";
mess.sub[CURSOR HERE]
}
}That should result in the following in the minibuffer:
> {substring(int, int) | substring(int) | subSequence(int, int)}Due to lack of good design in jde-complete.el (if you ask me) this defun will not handle all cases of completion. Even though it handles the most important once. In order to cover all cases lot of code from functions in jde-complete.el had to be copied, which I didn’t want to do.
