# YAML Ain't Markup Language

[15] Fix | Delete

#

[16] Fix | Delete

# This module provides a Ruby interface for data serialization in YAML format.

[18] Fix | Delete

# The underlying implementation is the libyaml wrapper Psych.

# == Usage

[21] Fix | Delete

#

[22] Fix | Delete

# Working with YAML can be very simple, for example:

[23] Fix | Delete

#

[24] Fix | Delete

# require 'yaml'

[25] Fix | Delete

# # Parse a YAML string

[26] Fix | Delete

# YAML.load("--- foo") #=> "foo"

[27] Fix | Delete

#

[28] Fix | Delete

# # Emit some YAML

[29] Fix | Delete

# YAML.dump("foo") # => "--- foo\n...\n"

[30] Fix | Delete

# { :a => 'b'}.to_yaml # => "---\n:a: b\n"

[31] Fix | Delete

#

[32] Fix | Delete

# == Security

[33] Fix | Delete

#

[34] Fix | Delete

# Do not use YAML to load untrusted data. Doing so is unsafe and could allow

[35] Fix | Delete

# malicious input to execute arbitrary code inside your application. Please see

[36] Fix | Delete

# doc/security.rdoc for more information.

# == History

[39] Fix | Delete

#

[40] Fix | Delete

# Syck was the original for YAML implementation in Ruby's standard library

[41] Fix | Delete

# developed by why the lucky stiff.

[42] Fix | Delete

#

[43] Fix | Delete

# You can still use Syck, if you prefer, for parsing and emitting YAML, but you

[44] Fix | Delete

# must install the 'syck' gem now in order to use it.

[45] Fix | Delete

#

[46] Fix | Delete

# In older Ruby versions, ie. <= 1.9, Syck is still provided, however it was

[47] Fix | Delete

# completely removed with the release of Ruby 2.0.0.
