indent for Ruby, to reformat it

[Phlip]

Rubies:

I'm writing a Ruby script and I'm too lazy to type the indentations and
linefeeds correctly.

I started on this jag assuming that an indent for Ruby would only be a
Google away.

I can't find one. Has anyone written a little script that even begins to
reformat Ruby into neat blocks?

(Don't flame; I promise not to need it again!)

Um..... Vim!!! ;-)

I will use it, just this once, if you divulge which bizarre series of
cryptic keystrokes will do it...

I let ruby-mode.el do it

Thanks. That did... something. Now I clean the tabs up with MSDev.exe, and
search-and-replace whatever stereotypical attrocities gg=G did.

I assume Vim detected Ruby from the file extension?

I let ruby-mode.el do it

Sorry - Emacs is the devil I /don't/ know. ;-)

Does that go and install vim for the user?

Vim's Ruby indentation has actually worked very well for me, although
the syntax coloring gets confused at times. And yes, Vim detects the
.rb and indented accordingly.

It seems to have identified SH scripts. It broke everything up at bizarre
intervals, screwed up the regular expressions, and turned => into = >.

(Fresh Fedora with the vim-common rpm installed, and Ruby installed from its
tar.gz file...)

I just did it by hand.

 

[Kirk Haines]

Ok! Just pop it open, then type 'G=gg'. See more Vim indenting tricks at
http://www.vim.org/tips/tip.php?tip_id=83

I use vim a lot, but have never asked it to indent my code for me. And
judging by the results that I just got, I won't do so again any time soon.
At least on my machine, with what is, admittedly, probably old and outdated
Ruby support, the results are awful.

Hack up three lines of Emacs Lisp to get the Emacs ruby-mode to do the
indentation for you? I usually get good results with XEmacs indenting my
code for me, although I don't have a quick and dirty way to do it via
the command line at hand.

Yes, that's what I meant.

xemacs -batch foo.rb -eval '(indent-region (point-min) (point-max) nil)' -f save-buffer -kill

With a modern setup, bad results are an exception rather than a rule.

The machine(s) are hardly ancient. One is a Gentoo box that has not had any
vim related stuff updated for about 6 months, and the other is an RHEL3 box.
Hardly non-modern. Just not cutting edge. The results are worse than bad
when I ask vim to indent the same code on either.

Okay. After spending some time with it, here's the secret:

Download a recent version of vim-ruby from Rubyforge:

http://rubyforge.org/frs/?group_id=16&release_id=3083

Follow the instructions found there or on the vim-ruby page:

http://vim-ruby.rubyforge.org

to install, and then make sure your .vimrc is setup to make use of what you
just installed.

The last bit is important. Otherwise, you get really nasty looking
indentation.

After having followed those steps, the indentation looks pretty good. I've
tested it on half a dozen files of varying lengths and code complexities, and
it seems to do what it should.

To be explicit, you need at least:

set nocompatible
syntax on
filetype on
filetype indent on
filetype plugin on

If you report them as bugs someone might try and fix them. ;-)
