自从ruby 1.9.3以来,Psych是默认的yaml引擎

为什么,为什么心理在其输出中添加换行符？请查看以下示例.

ruby -v # => ruby 1.9.3p374 (2013-01-15 revision 38858) [x86_64-linux]
require 'yaml'

"this absolutely normal sentence is more than eighty characters long because it IS".to_yaml
# => "--- this absolutely normal sentence is more than eighty characters long because it\n    IS\n...\n"

YAML::ENGINE.yamler = 'syck'

"this absolutely normal sentence is more than eighty characters long because it IS".to_yaml
# => "--- this absolutely normal sentence is more than eighty characters long because it IS\n"
