But after using Ruby for a year, seeing that in C/C++
doesn’t bother me as much. (In fact, the brace on the first
line is a coding standard for the bsd kernel, so I guess
it must not be all that bad. :slight_smile:

And Niklaus Wirth used to do it in Pascal (which
he invented). I just never cared for it. I like
to see things match vertically.

Also, this style has never bothered me in Ruby. I’m not sure why.

Likewise. I think it’s because Ruby forces you
to do it that way, which could be an annoyance if
you don’t like it; but Ruby has sooo many features
that compensate for that.

For an analogy: Suppose knuckle-cracking annoys
you. If Roseanne Barr sat in your living room
cracking her knuckles, you’d be highly annoyed.
But if Kate Moss did it, you wouldn’t mind so much.

What’s really unfortunate, though, is that Vim has some killer features
dealing with {…} blocks (on account of its C heritage and the plain
ubiqity of such blocks.

For example, you can delete, change, indent, or do whatever you like to the
contents of {…} (or (…), […], etc.) in an instant, no matter where
the
cursor is in the block.

Obviously, this functionality does not apply to do…end blocks. Despite
this loss, I still use do…end because it seems more fitting for Ruby.

If you can’t indent a do-end block by starting at the “do” line and
typing “>/end^M” then I might be willing to go out on a limb and
say that your block is trying to do too much and needs to be
refactored.

:wink:

Seriously, no offense meant.

– Dossy

That’s a fair point, and I would never (admit to) having a do…end block of
more than 10 lines! :wink:

Anyway, by “indenting a block” I meant “correcting the indentation”, not
“increasing the indent”. The former is handy when you’ve moved some code into
the do…end block and require all the indentation to be fixed up.

This is fine if you do not expect to share your code with others who choose
not to use vim. There are actually two common denominators: one for your own
ease and one for others. Tabs allow others to view with their own
preferences. Some use two spaces, some four, etc. for a tab. Spaces force
others to use your preferences.

True. Vim’s = (reindent) doesn’t Do The Right Thing for me and
especially breaks when do/end is used instead of {}.

Before:

[1, 2, 3].each do |x|

After =4j:

Not very useful in either case. At least in the do/end, once it
unindents everything on you, you could go in and manually reindent
with >> …

For some reason that seems to be the default in a lot of installations of
xemacs that other people around here use. This whole topic seems to be a
longstanding flame subject, too. It is well summed up here:

Hmmm. I believe emacs can be made to EAT UP little innocent spaces and
comvert them to tabs of your liking and vice versa.

Anyhow, while off-topic I have to remark on the similarities between emacs

Vim users may notice that the filetype plugin for Ruby sets up exactly
this; it changes shiftwidth to the most evil value in common use (2),
but does not set tabstop or expandtab, resulting in autoindent working
at 2, you working at tabstop, and if you haven’t set expandtab, them
mixing together into a horrible tab vs space war.

Space users: echo “set expandtab” >>~/.vimrc

Tab users: echo -e “source $VIMRUNTIME/ftplugin/ruby.vim\nsetlocal
sw=8” >~/.vim/ftplugin/ruby.vim

Two points:

  1. You can use :scr[iptnames] to find out which scripts/plugins have been
    sourced.

  2. I’ve become the maintainter of the ruby indent file, unless anyone disagrees
    :wink: I’m no good at writing indent rules yet. Any bug reports/solutions much
    appreciated. At the moment there are two that I’m aware of (the follwing are

def cartesianProduct(denumerable, &productBlock) #finite,finite is broken :frowning:
d = self.class.new
end

p = proc {
$_ }
x = 1

The second case is hardly important as it’s unusual code style, but the first
is very important. If an “inline” comment ends in ( or . or , or …
probably some others, the next line can’t be indented correctly. Again, any
help much appreciated.

Make sure you have “filetype indent on” (and “filetype plugin on”) in your
.vimrc. The rest will follow automatically. The online help explains
these, but I just take them on faith as commands that make stuff work.
