Region dependent key bindings

[witek]

I have bound the key w to meow-mark-symbol. Now when I press w a symbol is marked. When i press w again nothing changes. It would be nice if w would meow-next-symbol when a region already exists.

Is there a simple way to set this up?

Is there a reason not to have such region dependent key bindings?

(defun my-meow-mark-symbol ()
  (interactive)
  (if (use-region-p)
      (call-interactively 'meow-next-symbol)
    (call-interactively 'meow-mark-symbol)))

Well, you can have any command you like, there's really no restriction here. Personally, I'm against "Do-What-I-Mean" style command. With a DWIM style command, you call once it does one thing, you call again, it does something else. I want every commands work as how they are described. If we have a command that named as "mark a symbol", it should mark a symbol, that's it.

You may notice there are some "DWIM" behaviors in Meow, for example, you can use meow-kill to kill a region, without a region, it kills to the end of line. That's because we have a mechanism for no-region fallback behavior, it's decoupled and configurable.

Hi,
Is there anything similar to this behaviour in objed.el?

This seems useful in order to move from one thing to next/prev. I've found myself implementing this in normal mode:

'("[" . backward-paragraph)
'("]" . forward-paragraph)

But maybe something like this could work?

• meow-inner-of-thing
• paragraph
• meow-next-thing

No, there isn't. Just use built-in commands for paragraphs, sentences movement.

Oh, I didn't check that one. Thanks!
