Bug 282976 – [WebDriver][BiDi] Support formatting strings in log.entryAdded events

• Component: WebDriver
• Status: NEW

[Lauro Moura]

The Initial patch in bug271956 will support only space-separated arguments, implementing step 5 from the spec:

Spec: https://w3c.github.io/webdriver-bidi/#event-log-entryAdded

4. If Type(args[0]) is String, and args[0] contains a formatting specifier, let formatted args be Formatter(args). Otherwise let formatted args be args.

    Note: The formatter operation is underdefined in the console specification, formatting can be inconsistent between different implementations.

5. For each arg in formatted args:

    1. If arg is not the first entry in args, append a U+0020 SPACE to text.

    1. If arg is a primitive ECMAScript value, append ToString(arg) to text. Otherwise append an implementation-defined string to text.
