released: { name: Syck, version: 0.70 }
for: [ Ruby, PHP, Python ]
by: why the lucky stiff
about: >
Syck is a YAML parser, an extension for scripting
languages, written in C.
So what is YAML? YAML is a new language for data.
Describe objects in plain text. Load the data into
your scripting language as arrays, dictionaries,
classes, or primitives.

Syck Benchmarks: http://www.whytheluckystiff.net/arch/2003/03/19
status: >
Syck is about 95% compliant with the YAML spec. Largely, small
issues remain.
The extensions are quite usable. Ruby, PHP and Python
can load from a string containing YAML.
Ruby has support for stream loading, type handling, YPath, Okay.
This release includes an amount of Ruby code comprising the 0.60
release of YAML.rb.
benchmarks: >
Syck is quite speedy, although not as swift as most language's
native serialization.
Syck runs at about:
50-60% of the speed of Ruby's Marshal.
65-90% of the speed of PHP's deserialize().
600% of the speed of Python's Pickle.
50-60% of the speed of Python's cPickle.
(Based on various types of structured data.)
