Textmate like code block alignment (ruby-mode)

Textmate like code block alignment (ruby-mode)

[Marcelo de Moraes Serpa]

Hey list,

I have ruby-mode setup and it works pretty well. One thing though is
that it doesn't automatically align blocks, and I have to type C-a TAB
to make it align the end with a def for example:

def func <when I press ENTER here>
      |<the pointer goes here>

I'd like it to behave like Textmate, where when you press enter after
the beginning of a code block, it automatically aligns the end to like
so:

def func <when I press ENTER here>
|<the cursor goes here, where it should be>

It's really annoying having to align manually.

Any ideas?

Thanks in advance,

Marcelo.

You could try binding RET to newline-and-indent (bound to C-j by default).

Try something like this (untested):

(add-hook 'ruby-mode-hook
  (lambda ()
    (define-key ruby-mode-map (kbd "RET") 'newline-and-indent)))

By the way, you normally don't have to move the cursor anywhere to
indent the current line. Just hit TAB with the cursor anywhere on the
line you wish to indent "correctly" and it will work just as well.

Hi Deniz,

Thanks for being so helpful ;)

Well, my config has snippets attached to TAB too, so if I hit TAB, it
will try to complete "end". I'm using a fork of emacs-starter-kit,
and, although I have modified it a lot already, I didn't have the time
to peek into it the way I wanted so as to understand how things are
wired up, I'll need to to that eventually.

Anyway, thanks for the suggestion. Using C-j already had this
behaviour built-in btw,

Marcelo.

You could try tabkey2 or smart-tab to get both indentation and
snippets, see http://www.emacswiki.org/emacs/TabCompletion
