shortcut for align-regexp

shortcut for align-regexp

[Jannis]

Hi emacs users,


this most probably is a beginners question ... googeling however yielded 
now exlanation suitable for my emacs experience.

I would love to bind single key combination (like C-a) to the 
align-regexp command and use = and <- as alignment regexpressions. How 
would I do this?

Without this I always have to type:

M-align-regexp RET <- RET


Thanks a lot
Jannis

The command align-regexp is written to prompt you for a regular expression if you use it interactively.

The following code does what you describe you want.

    (defun my-common-align (begin end)
      "Align text in the region on '=' and '<-'."
      (interactive "r")
      (let ((common-align-regexp "\\(?:=\\|<-\\)"))
	(align-regexp begin end common-align-regexp)))
    (global-set-key "\C-a" 'my-common-align)

The choice of key is yours, but `C-a' is move-beginning-of-line almost everywhere. I might recommend `C-c a' instead.
