CSSPool

DESCRIPTION:

CSSPool is a CSS parser. CSSPool provides a SAC interface for parsing CSS as well as a document oriented interface for parsing CSS.

FEATURES/PROBLEMS:

CSSPool now depends on libcroco and interfaces with libcroco via FFI. This means that if libcroco isn’t installed in one of your default library paths, you’ll need to tell CSSPool where to find the libcroco shared library. This is typically the case for people using OS X and installing libcroco via macports.

You can tell CSSPool where to find the libcroco shared library in a couple ways. The first way is to set LD_LIBRARY_PATH to point at the correct directory. Just do this:

$ export LD_LIBRARY_PATH=/opt/local/lib

Then run your script.

The second way is to tell CSSPool specifically where to find the dynamic library. To do that, just set the LIBCROCO environment variable. On OS X, I would do this:

$ export LIBCROCO=/opt/local/lib/libcroco-0.6.dylib

Then run my script.

SYNOPSIS:

doc = CSSPool.CSS open('/path/to/css.css')
doc.rule_sets.each do |rs|
  puts rs.to_css
end

puts doc.to_css

REQUIREMENTS:

libcroco (on OS X do “sudo port install libcroco”)

INSTALL:

sudo gem install csspool
