The options hash to to_yaml doesn't seem to have effect.

[ola@…]

From the yaml4 document, this code:

puts [[ 'Crispin', 'Glover' ]].to_yaml( :Indent => 4, :UseHeader => true, :UseVersion => true )

should result in this output:

--- %YAML:1.0
-
    - Crispin
    - Glover

but what I get in "ruby 1.8.4 (2005-12-24) [i386-mswin32]"

is this:

--- 
- - Crispin
  - Glover

The to_yaml call seems to totally ignore the options specified.

There is a good post that diagnoses the problem here: http://www.arkanis-development.de/weblog/2007/6/20/options-for-rubys-%40to_yaml%40-method

Replying to ola@ologix.se:

From the yaml4 document, this code: {{{ puts [[ 'Crispin', 'Glover' ]].to_yaml( :Indent => 4, :UseHeader? => true, :UseVersion? => true ) }}} should result in this output: {{{ --- %YAML:1.0 - - Crispin - Glover }}} but what I get in "ruby 1.8.4 (2005-12-24) [i386-mswin32]" is this: {{{ --- - - Crispin - Glover }}} The to_yaml call seems to totally ignore the options specified.
