如何在Emacs中以编程方式查找在哪个映射中键绑定(How to find in which map a key binding is from programmatically in Emacs)

例如,通过Ch k,我可以向Emacs询问“C在这个缓冲区中做了什么?”。 如果当前的缓冲区是我设置的Lisp缓冲区,Emacs会回答paredit-forward-slurp-sexp。 从这一点上,我可以猜测,C权与paredit-forward-slurp-sexp的绑定来自paredit模式映射,因为命令名由paredit加上前缀,但这是一种启发式。 我该如何以编程方式来做这件事,也就是说,我怎样才能问“在这个缓冲区中来自哪里的C-right的绑定?”

在这种情况下,编写一个函数检查当前全局地图,当前主要模式地图,paredit-mode-map,paredit-forward-mode-map,paredit-forward-slurp-mode-map,paredit-forward-slurp-sexp-模式映射的唯一途径?


For example, with C-h k I can ask to Emacs "what does C-right do in this buffer?". If the current buffer was a Lisp buffer in my setup, Emacs would answer paredit-forward-slurp-sexp. From that, I can guess that the binding of C-right to paredit-forward-slurp-sexp is from the paredit mode map because the command name is prefixed by paredit, but that's a heuristic. How can I do that programmatically, i.e., how can I ask "where is the binding of C-right in this buffer coming from?"

Is writing a function that in this case checks current global map, current major mode map, paredit-mode-map, paredit-forward-mode-map, paredit-forward-slurp-mode-map, paredit-forward-slurp-sexp-mode-map the only way?

最满意答案

这些是文本文件,因此它们不包含任何包含这些信息的头文件。

使用__version__属性指定版本并要求Microsoft编写此功能。


Those are textfiles and thus they don't contain any header to include such information.

Specify the version with __version__ attribute and ask Microsoft to write this functionality.
