Description
I was examining our (somewhat neglected) Stylelint config recently and found declaration-property-value-no-unknown, which IIUC may be enabled by default soon. Enabling this rule turned out to be very helpful for us, finding a number of bugs in our CSS :)
However, it took me a while to figure out how to make it work with rewrite-url(). Eventually I came up with this (the function-no-unknown exception is included for completeness):
{
"rules": {
"declaration-property-value-no-unknown": [
true,
{
"typesSyntax": {
"url": "| rewrite-url( <string> )"
}
}
],
"function-no-unknown": [
true,
{
"ignoreFunctions": ["rewrite-url"]
}
],
}
}This extends <url> to also accept rewrite-url() type values, which may be somewhat overly broad but works like a charm for us. Technically url() takes url( <string> <url-modifier>* ) but I wasn't sure if rewrite-url() supports these (theoretical?) modifiers.
What do you think?
