如何获得基本的App< - > Emacs集成？ [英] How do I get basic App<->Emacs integration?

问题描述

有一大堆应用程序将Emacs与外部进程集成在一起。 GDB是一个想到的。我可以从emacs控制GDB，然后在屏幕上获得反馈。

There are a bunch of applications out there that integrate Emacs with external processes. GDB is one that comes to mind. I can control GDB from emacs and then get feedback on the screen.

我想用我的应用程序向这个方向做某事。

I'd like to do something in that direction with my application.

这是我想要的：

• 建立我和emacs之间的连接。我可能会开始一个新的emacs过程，并将其压缩到我的GUI中。


• 告诉emacs显示一个文件。 （容易与emacsclient）


• 告诉emacs滚动到一个特定行号的中心，hilite或只是将光标移动到那里。
  
  
  
  
  • 可能真正的问题是如何从我的外部应用程序发送任意的elisp代码以执行emacs。
  
  
  • 我不会说elisp，但这将是一个很好的借口学习
  
  
  • establish a connection between me and emacs. I'd probably start a new emacs process and slurp it into my GUI
  • tell emacs to display a file. (easy with emacsclient)
  • tell emacs to scroll to center on a particular line number and hilite or just move the cursor there.
    • Probably the real question is how do I send arbitrary elisp code from my external app for emacs to execute.
    • I don't speak elisp, but this would be a great excuse to learn
    
    
    • 即使没有可点击性，发送消息的键绑定也是一个开始。 （但我知道可点击的事情是可能的，所以我问）
    
    

    我知道这是可能的（在emacs中是不可能的），但是我不知道从哪里开始googling。

    I know that this is all possible (what isn't possible in emacs?), but I just don't know where to start googling.

    推荐答案

    可点击区域

    窗口小部件库可以让您将缓冲区的一部分按钮（也是无线电框，复选框） ，列表），当您单击它们时将执行elisp。例如：

    The widget library would let you make parts of your buffer into buttons (also radio boxes, check boxes, lists), which will execute elisp when you click them. For example:

        (require 'widget)
    
    (defun simple-widget-example ()
       (interactive)
      (switch-to-buffer "*Simple widget example*")
    
      (let ((inhibit-read-only t))
        (erase-buffer))
    
      (let ((all (overlay-lists)))
        ;; Delete all the overlays.
        (mapcar 'delete-overlay (car all))
        (mapcar 'delete-overlay (cdr all)))
    
      (widget-insert "Sample button\n")
      (widget-create 'push-button
             :notify (lambda (&rest ignore) 
                   (message "Poop! Ha Ha!"))
             "Press Me")
    
      (use-local-map widget-keymap)
    
      (widget-setup))
