Two suggestions for Kernel#y:
-
Make it private, like Kernel#p.
-
Let it take multiple args, like Kernel#p, something like:
y 1,2,3
— 1
— 2
— 3
=> nil
Anyone see any sense in these?
I could add
- Tell everyone about it because it’s very useful

Yes, please tell us more. What is it ?
Thanks,

do tell. ‘y’ for yaml?

Create a bunch of stuff:
ahash = {:a => 1, ‘BB’ => 2, 7 => ‘seven’, ‘d’ => 10}
astring = RUBY_VERSION + ’ ’ + RELEASE_DATE
afloat = Math::PI
anarray = [‘c’, 111, Exception.new(‘Oops’)]
Bunch it more:
anarray.push(ahash).push(astring).push(afloat)
p anarray # for comparison
puts ‘.’*107, ‘’
See what yaml’s y shows
require ‘yaml’ # <-------------------------#
y anarray

wow. very, very cool.
definitely should be changed to
def y(*args)
args.each{|a| super a}
end
though.

and, yes, as well. very good, thank you. checked into syck cvs now.
ruby 1.9 branch shortly.

close, instead let’s output multiple inputs as a YAML stream, with each
having their own document:
module Kernel
def y( *x )
puts( if x.length == 1
YAML::dump( *x )
else
YAML::dump_stream( *x )
end )
end
private :y
end
works the same, but allows Kernel#y to dump headless documents if only
one input is sent.
great suggestions, cool, cool…

Hm. Where’s the difference between “puts obj.to_yaml” and “y obj” apart from
less typing?

Actually, that’s pretty much the definition from yaml.rb:
module Kernel
def y( x )
puts x.to_yaml
end
end
Kernel#y and Object#to_yaml are analogous to Kernel#p and
Object#inspect. Both #y and #p are convenient for debugging and irb. And
there’s also #pp, which is nice to have, too.
