nrepl.el:如何将clojure缓冲区形式改为nrepl缓冲区而不是echo区域?

标签: emacs clojure

我正在使用git的nrepl.el(0.1.6预览,通过el-get配方),我想要clojure缓冲区evals:Cx Ce,CMx,Cc Cr for form,top-level form and region分别将自己发送到nrepl缓冲区并进行评估,而不是默认的评估屏幕外的行为,结果返回到echo区域。

有没有办法做到这一点,或者是否有另一组用于此目的的键绑定,我不会通过他们的描述来识别?

感谢。

nrepl.el目前不支持您描述的行为。

但好消息是你在emacs-land中,所以应该可以编写自己的自定义处理程序来将输出定向到nrepl缓冲区并根据需要调整你的键绑定。

例如,这相当于C-x C-e,但是将评估结果发送到repl缓冲区而不是迷你缓冲区:

(defun my-interactive-eval-to-repl (form)
  (let ((buffer nrepl-nrepl-buffer))
  (nrepl-send-string form (nrepl-handler buffer) nrepl-buffer-ns)))

(defun my-eval-last-expression-to-repl ()
  (interactive)
  (my-interactive-eval-to-repl (nrepl-last-expression)))

这是一个也将错误发送到正确的窗口的版本:

(defun my-nrepl-handler (buffer)
  "Make an interactive eval handler for buffer, but emit the value or out to the repl, not the minibuffer."
  (nrepl-make-response-handler buffer
                               (lambda (buffer value)
                                 (progn
                                   (nrepl-emit-result (nrepl-current-repl-buffer) value t)
                                   (nrepl-emit-prompt (nrepl-current-repl-buffer))))
                               (lambda (buffer out)
                                 (nrepl-emit-interactive-output out)
                                 (nrepl-emit-prompt (nrepl-current-repl-buffer)))
                               (lambda (buffer err)
                                 (message "%s" err)
                                 (nrepl-highlight-compilation-errors buffer err))
                               (lambda (buffer)
                                 (nrepl-emit-prompt buffer))))

(defun my-interactive-eval-to-repl (form)
  "Evaluate the given FORM and print value in the repl."
  (remove-overlays (point-min) (point-max) 'nrepl-note-p t)
  (let ((buffer (current-buffer)))
    (nrepl-send-string form (my-nrepl-handler buffer) (nrepl-current-ns))))

(defun my-eval-last-expression-to-repl ()
  (interactive)
  (my-interactive-eval-to-repl (nrepl-last-expression)))

(eval-after-load 'nrepl
  '(progn 
     (define-key nrepl-interaction-mode-map (kbd "C-x C-e") 'my-eval-last-expression-to-repl)))

由于此处提供的解决方案均不适用于我的版本,因此我想出了自己的实现:

(defun eval-in-nrepl ()
  (interactive)
  (let ((exp (nrepl-last-expression)))
    (with-current-buffer (nrepl-current-repl-buffer)
      (nrepl-replace-input exp)
      (nrepl-return))))

(eval-after-load 'nrepl
  '(define-key nrepl-interaction-mode-map
     (kbd "C-x C-.")
     'eval-in-nrepl))

它结合C-x C-。达到预期的行为。
