Gossip Girl says: csspool version 0.2.0 has been released! - [http://csspool.rubyforge.org/](http://csspool.rubyforge.org/) CSSpool (pronounced “cesspool”) is a validating SAC parser for CSS. The parser calls methods on a document handler depending on what it has found. CSSPool currently only supports CSS 2.1. CSSPool will not yield invalid properties or selectors. Changes: ## 0.2.0 - Added CSS::SAC::Parser#parse\_rule to parse a single rule. - Added CSS::StyleSheet#find\_rule for finding a particular rule. - Added CSS::StyleSheet#rules\_matching for finding all rules matching a node. - Added CSS::StyleSheet#create\_rule for creating a new rule. - Added CSS::StyleSheet#find\_all\_rules\_matching for finding all rules that match any node in the passed in document. - Added .eql? to selector AST - Added .hash to selector AST - Added .eql? to LexicalUnits - Added .hash to LexicalUnits - Added CSS::StyleSheet#to\_css - Added CSS::StyleSheet#reduce! - CSS::StyleSheet is now the default document handler - [http://csspool.rubyforge.org/](http://csspool.rubyforge.org/) This is a tenderlovemaking dot com joint. ---

I’ve been toying around with the lib and I noticed some issues: - the Manifest tends to contain a .DS\_Store entry which crashes rake package so rake install\_gem (the way i usually install csspool) fails with: “Don’t know how to build task ‘.DS\_Store’”. - the example on the homepage doesn’t work for me. I get “uninitialized constant CSS::SAC::Parse (NameError)” when I try to run it. However, the earlier examples, which show inheriting from CSS::SAC::DocumentHandler work for me, if i also add a “require ‘rubygems’” first - the following css breaks css breaks the parser and makes it ignore all rules and declarations after the error. In css, with browsrs at least, an error should just ignore the respective property or properties, so I was expecting similar behaviour. I’ll try to get my hands into the ragel stuff, but this might take a while since I haven’t done any before, saw a presentation at euruko, tho :). So, the bad css that’s preventing me from getting a pink background and a blue p: a { color: red; } body { border: solid 1px; #000; color: pink; } p { color: blue; } > This is a tenderlovemaking dot com joint. > > – > Aaron P. > [http://tenderlovemaking.com/](http://tenderlovemaking.com/) Again, thanks a lot for this project, it’s looking really cool and useful :).

Nothing there is going to give you a pink background. you need to put: background-color: pink; Inside of either declaration body or p. ---

Hi John, Yes, and the error is there on purpose. I was reporting a bug in the way such errors are handled by the csspool parser. Instead of just skipping the declarations you correctly noticed in the css, it stops parsing the rest of the css file. I would have expected the color: pink for body and p { color: blue; } to get parsed in spite of the error. Cristi ---

I’m always amazed at browsers parsing css so quickly anyway. Even more amazed that they usually get it right. (well not all of them) ---

Try CSS::SAC::Parser. > a { color: red; } > body { border: solid 1px; #000; color: pink; } > p { color: blue; } Great! Thanks for the test case. I’ll add that to my test suite and get it working. > Again, thanks a lot for this project, it’s looking really cool and useful :). > Thanks. Keep the bugs coming, I need them to make it mo betta.
