2007-02-27 17:21:26 Ruby Indentations and Blocks

John started this with this piece of code:
( ruby ) ✂

[
    Group.new( :kind => 'committee' ),
    Group.new( :kind => 'topic' ),
    Group.new( :kind => 'adhoc' )
].each do |g|
    assert( g.save! )
end

  1  [
  2      Group.new( :kind => 'committee' ),
  3      Group.new( :kind => 'topic' ),
  4      Group.new( :kind => 'adhoc' )
  5  ].each do |g|
  6      assert( g.save! )
  7  end

And I'll just mention this other possibility:
( ruby ) ✂

[ 'committee', 'topic', 'adhoc' ].map {
    |kind| Group.new( :kind => kind )
}.each do |g|
    assert( g.save! )
end

  1  [ 'committee', 'topic', 'adhoc' ].map {
  2      |kind| Group.new( :kind => kind )
  3  }.each do |g|
  4      assert( g.save! )
  5  end

Which only really works out as well as it does because of the uniformity of the initial array.

Although, for this specific example, couldn't you just do this?
( ruby ) ✂

[ 'committee', 'topic', 'adhoc' ].each do |kind|
    assert( Group.new( :kind => kind ).save! )
end

  1  [ 'committee', 'topic', 'adhoc' ].each do |kind|
  2      assert( Group.new( :kind => kind ).save! )
  3  end
