mess.js is an attempt to use less.js to
|
|
compile cascadenik-formatted styles.
|
|
|
|
it is inspired by but incompatible with
|
|
Cascadenik [1].
|
|
|
|
|
|
= Changes from Cascadenik:
|
|
|
|
- MML files are assumed to be JSON, not XML
|
|
- Instead of the name attribute of the TextSymbolizer
|
|
and ShieldSymbolizer being a part of the selector, it
|
|
is a property of a rule. Thus the evaluation is less
|
|
complex and one can use expressions in names.
|
|
|
|
cascadenik:
|
|
|
|
#world NAME {
|
|
text-face-name: "Arial";
|
|
}
|
|
|
|
mess:
|
|
|
|
#world {
|
|
text-name: "NAME";
|
|
text-face-name: "Arial";
|
|
}
|
|
|
|
- Pseudoelements are supported to append extra
|
|
symbolizers onto single matched rules.
|
|
|
|
#world {
|
|
line-color: #fff;
|
|
line-width: 3;
|
|
}
|
|
|
|
#world::outline {
|
|
line-color: #000;
|
|
line-width: 6;
|
|
}
|
|
|
|
- outline and inline are removed, having been replaced
|
|
with pseudoelements.
|
|
- names of styles in XML are derived from layer names,
|
|
rather than being entirely autogenerated
|
|
- less.js variables and expressions are supported
|
|
- fontsets are supported by simply specifying multiple
|
|
font names
|
|
|

mess.js is based on less.js [2], a CSS compiler
|
|
written by Alexis Sellier. It includes
|
|
underscore.js [3].
|
|
|
|
like less, mess.js provides a binary in bin/,
|
|
named mess, although it is designed primarily
|
|
for usage as a library.
