Undocumented MapCSS operator

[frodrigo]

addresses.mapcss and combinations.mapcss validator contains the undocumented "=*" predicate operator.
The "*=" is in wiki, but nor in mapccs validator code.
See: https://josm.openstreetmap.de/wiki/Help/Styles/MapCSSImplementation#condition_selector_operators

I don't really understand what should be changed or added and where. Could you please explain it in more detail?

[frodrigo]

Not sure. But the on the wiki there is the operator "*=" (star then equal), the mapCss code use "=*" (equal then star). If it's the same operator I think wiki is right and mapCCS files + JOSM are wrong. Shoul be confirmed by other MapCSS implementation.

(I'm writing a mapCSS parser)

No, these are two different things:

• *= is substring match like explained in the table you linked
• =* or = * means that the following is not the value but another key. This is explained below the table.

Ho Ok. Sorry I miss this point.

(BTW I found another undocumented feature, but it's obvious, >:pseudo_class is not in the wiki)

Replying to frodrigo:

Thats a combination of the child selector and a pseudo class. I don't think this needs extra documentation as both are explained. (There is also already one example of this combination: relation:unclosed_multipolygon >:open_end node)
