//
|

// url
|
||||
//
|
||||
// Converts a string to a URL or results in an error if the string is not a valid URL. The URL must be an absolute URI
|
||||
// or an absolute path.
|
||||
//
|
||||
// url(<string>) <URL>
|
||||
//
|
||||
// Examples:
|
||||
//
|
||||
// url('https://user:pass@example.com:80/path?query=val#fragment') // returns a URL
|
||||
// url('/absolute-path') // returns a URL
|
||||
// url('https://a:b:c/') // error
|
||||
// url('../relative-path') // error
|
||||
//
|
||||
// isURL
|
||||
//
|
||||
// Returns true if a string is a valid URL. The URL must be an absolute URI or an absolute path.
|
||||
//
|
||||
// isURL( <string>) <bool>
|

//
|

// Examples:
|

//
|

// isURL('https://user:pass@example.com:80/path?query=val#fragment') // returns true
|
||||
// isURL('/absolute-path') // returns true

// getScheme / getHost / getHostname / getPort / getEscapedPath / getQuery
|

//
|

// Return the parsed components of a URL.
|
||||
//
|
||||
// - getScheme: If absent in the URL, returns an empty string.
|
||||
//
|
||||
// - getHostname: IPv6 addresses are returned with braces, e.g. "[::1]". If absent in the URL, returns an empty string.
|
||||
//
|
||||
// - getHost: IPv6 addresses are returned without braces, e.g. "::1". If absent in the URL, returns an empty string.
|
||||
//
|
||||
// - getEscapedPath: The string returned by getEscapedPath is URL escaped, e.g. "with space" becomes "with%20space".
|
||||
// If absent in the URL, returns an empty string.
|
||||
//
|
||||
// - getPort: If absent in the URL, returns an empty string.
|
||||
//
|
||||
// - getQuery: Returns the query parameters in "matrix" form where a repeated query key is interpreted to
|
||||
// mean that there are multiple values for that key. The keys and values are returned unescaped.
|
||||
// If absent in the URL, returns an empty map.
