Hi all,
I just noticed that the MapCSS 0.2 wiki seems to state that properties
specified by URLs should take this form:
icon-image: url/goes/here.png;
I'd like to propose changing to this instead:
icon-image: url('url/goes/here.png');
For two reasons:
1) It agrees with the CSS spec.
2) It's much easier to parse. Under the old scheme, either the tokeniser would
output something like <identifier 'url'> <symbol '/'> <identifier 'goes'>
<symbol '/'> <identifier 'here'> <symbol '.'> <identifier 'png'>, and the
parser would have to have a magic rule along the lines of "consume everything
up to the <symbol ';'> and smush it together into a string"; or the tokeniser
would have to be aware of the state of the parser, and produce a <string
'url/goes/here.png'> token instead of the above iff the parser is in this
state. Both these solutions seem comparatively ugly, compared to the CSS
solution, which allows for a simple BNF rule:
<url> ::= "url" "(" <quotedString> ")"
Would appreciate any comments.
Thanks
Tom Davie
