[e4-dev] CSS Engine and CSS3 SAC Parser with FreeCC?

[Angelo zerr <angelo.zerr@xxxxxxxxx>]

Hi,

Today we have several SAC Parser implementation available (Batik, Flute,...).
E4 CSS engine is today based on Batik SAC implementation, I think for IP reason.

Problem is that SAC Parser implementation manage only CSS2, not CSS3.
You can find CSS3 features at http://www.w3.org/TR/css3-selectors/

Why CSS3? Because it gives some features like : 

* nth-child : which is very interesting to set CSS  style into row of SWT Table (eg : set a color to a particulary row like set blue color on odd row and set red color even row). Ex : 

TableItem:nth-child(odd) {
   color:blue;
}


TableItem:nth-child(even) {
   color:red;
}

* use namespace to disting CSS style for SWT Label and Custom Label. Ex : 

@namespace custom "com.mycompany.widgets"

Label {
   color:red;
}

custom|Label {
   color:blue;
}

 
With CSS2 SAC Parser, we cannot manage thoses cases. I think it's shame.
So I think it's time to think about CSS3 SAC Parser implementation. 

I don't know if Batik is interesting to support CSS3 SAC Parser, but I know that Jonathan Revusky, one creator of famous Freemarker project is perhaps interesting to implement CSS3 SAC Parser with her new project FreeCC which is Parser (it's a fork of JavaCC).

What do you think about the idea to implement CSS3 SAC Parser with FreeCC?
