[Laszlo-dev] dguide: Color chapter

[André Bargull]

These RegEx' from ViewSchema are responsible for the color-parsing, right?

Perl5Compiler compiler = new Perl5Compiler();
String s = "\\s*(-?\\d+(?:(?:.\\d*)%)?)\\s*"; // component
String hexDigit = "[0-9a-fA-F]";
String hexByte = hexDigit + hexDigit;
sRGBPattern = compiler.compile("\\s*rgb\\("+s+","+s+","+s+"\\)\\s*");

sHex3Pattern = compiler.compile("\\s*#\\s*(" + hexDigit + hexDigit + hexDigit + ")\\s*"); sHex6Pattern = compiler.compile("\\s*#\\s*(" + hexByte + hexByte + hexByte + ")\\s*");

Add that to the bug.

Clearly the parser sux.

Also, I discovered that if I say:

bgcolor="${iceblue}"

and iceblue is not defined in lz.colors, I get:

#000ceb

as my color. As in iCEBlue. It's like the parser is trying to find a hex string in there somewhere, and skipping over any initial non-hex characters. That seems pretty counter-intuitive to me, it not dead wrong.
