Re: [eclipse-incubator-e4-dev] TK-UI parser - why Flute?
|
Hi Angelo,
interesting. I also found another shortcoming of the batik parser: It
doesn't provide a Locator to obtain text ranges for property values,
which can be a problem when CSS files should be modified (we need this
in the RAP Theme Editor). Steadystate provides a Parser#getLocator
method, I didn't find anything similar in Flute.
What about the license of Flute? I recall this is a W3C license. Is this
compatible? If there is a chance to use this parser with Eclipse, I'd
like to have a closer look, too.
Best Regards, Ralf

Hi Kevin,
TK-UI CSS parser use Flute parser by default but you can use another SAC
Parser if you want.
Today I have founded 3 SAC parser implementation : Batik, Flute
easystate which implement CSS2 specification but not CSS3.
with easystate you mean steadystate, don't you?
Into TK-UI I wanted manage namespace described into CSS3 specification,
to write selector by setting package.
Imagine you have two classes Label
org.eclipse.swt.widgets.Label and my.Label
If you want disting selector between two Label, you can use CSS3
namespace and write his CSS :
@namespace swt "org.eclipse.swt.widgets";
@namespace my "my";
swt|Label {
color;red;
}
my|Label {
color;red;
}
So I try to update SAC Parser Batik, Flute...and I found Flute was the
easier to update, because Flute is based on JavaCC
where you have Parser.jj JavaCC file which desribe CSS2 grammar. I have
updated this file to manage CSS3 namespace.
See customized Flute parser at
http://tk-ui.svn.sourceforge.net/svnroot/tk-ui/org.akrogen.tkui.css/trunk/org.w3c.flute
Flute jar into distribution is 1-3 (it's my flute parser). The real
flute parser is 1-2 (2 means support CSS2).
Regards Angelo
I have used Flute Parser because I have improved it to manage CSS3
namespace.

Hi Angelo,
I was looking at your TK-UI css.core and noticed it uses the Flute
parser. I was wondering if you could discuss why you chose this
particular SAC parser? (vs. batik for example).
Regards
Kevin
