I need a code beautifier or formatter

Joao_Pedrosa2 · 14 June 2003 13:01

Hello,

I have some source code that is terribly formatted. It needs some good
indentation at least. But I am too lazy to do it all by hand.

Does anyone know a tool to do the job ?

Thanks in advance,
Joao

Vim can format Ruby code (visual select then press '=').

Michael

I use XEmacs in Ruby mode. It has an indent function, which you can
invoke in batch mode from the command line

xemacs -batch myprog.rb -eval ‘(indent-region (point-min) (point-max)
nil)’ -f save-buffer -kill

I hope this helps,

Tim

Hi Joao,

You could try a small program I wrote to do that: it’s by no means
complete, and will only handle a subset off all possible ruby programs
correctly. If I remember correctly it only handles programs that use
do…end instead of {…}, but maybe you can adapt it.

Cheers,

Han Holl

The emacs mode that comes with the distribution does a pretty good job as well.

Vim can format Ruby code (visual select then press ‘=’).

Ara.T.Howard1 · 14 June 2003 14:43

for me this simply lines eveything up in a column - could you post the
relevant bits of your .vimrc/.gvimrc or forward them to me directly?

this sounds like a great feature…

Nothing special in there, except the usual "syn on".

Make sure that the file is recognized as a Ruby source file. If it does
not end with .rb then ":setf ruby" will do it.

Hope this helps.

Nice link.

When I added the lacking bits to .vimrc it began formatting ok.

But it had some problem with

----- snip
def listjoin(channels)
channels.each do |c|^M
s = “join ##{c}”^M
@irconnector.sendToStatus s^M
@irconnector.sendToServer s^M
end^M
end^M
----- snip

But now it is pretty usable.

Thanks all,
Joao

I think I found the bug in indent/ruby.vim responsible for that (assuming
that you had in fact one or more spaces after ‘|c|’ and before the EOL):

You need this line in your .vimrc file:

filetype plugin indent on

Right on target

I am CCing to Gavin, as he probably would like to fix it.
