埃马克斯地图 <compile “python current-buffer-name”> 到热键

Question

If I do Mx <RET> compile <RET> , I get prompted for what to compile. What I want to compile is the current buffer in python, so I type python test.py <RET> . Now sometimes I get asked if I want to create a separate process, and I always want to say y (that is yes).

(define-key python-mode-map "\\Cb" 'compile) gives the following error:

(define-key global-map "\\Cb" 'compile) works, but that's far from what I need.

So, how can I map compile python current-buffer-name to "\\Cb" ?

Answer 1

Emacs does have the concept of modes. I guess you do not want to have the compilation of python to a global key.

Have you checked: http://www.emacswiki.org/emacs?action=browse;oldid=PythonMode;id=PythonProgrammingInEmacs

What you do is calling an external program. I'm sure there is a better suited way to do that in the python-mode.

If you want to pack more then one command to a key, you have to write some kind of wrapper this function contains all the things you are going to call.

The variable python-mode-map will not be defined until you load python-mode . The brute-force approach would be to (require 'python-mode) from your .emacs but you can avoid that somewhat more elegantly by only doing the define when python-mode is being invoked.

(add-hook 'python-mode-hook
          (lambda ()
            (define-key python-mode-map "\C-b" #'compile)))
