| Subject: | CSS::Parse::Heavy and CSS::Parse::Compiled don't work for me |
In trying to pin down the other bug I reported, I found that using CSS::Parse::Heavy or CSS::Parse::Compiled failed completely on the input file I was using. No error message was produced but the parse tree appeared to be completely empty.
A bit more experimentation revealed that these parsers cannot cope with the use of single quotes in property values, like this:
font-family: 'Trebuchet MS', 'Bitstream Vera Sans', sans-serif;
If I changed them to double quotes:
font-family: "Trebuchet MS", "Bitstream Vera Sans", sans-serif;
it worked fine. Both single and double quotes are valid in CSS.
Wherever single quotes appear in the input file, the parsers seem to give up (silently) at that point. I was getting a totally empty parse tree because the first block in my input file contained the above font-family spec (though not as the first line of the block -- the rest of the block was lost as well.)
CSS::Parse::Lite is unaffected by this bug, and is in any case several orders of magnitude faster so I'm not clear what the point of the alternative parsers is...
