Code generators should support multiple values for the [CallWith=] attribute

• Component: WebCore JavaScript
• Status: RESOLVED FIXED

[Kentaro Hara]

Currently we can specify only one value for one [CallWith=], like [CallWith=ScriptExecutionContext] or [CallWith=ScriptState].

To reduce redundant IDL attributes, we are planning to support multiple values for [CallWith=], like [CallWith=ScriptExecutionContext|ScriptArguments|CallStack]. In this bug, we make a change on code generators.

This doesn't seem specific to CallWith.  Should we give this a more general name like "ExtendedAttributeContains" or "AttributeContains"?

> Source/WebCore/bindings/scripts/CodeGeneratorV8.pm:1457
>  sub GenerateCallWith

Should this function error out if there's something in the CallWith attribute that we don't understand?

Makes sense. Renamed to "ExtendedAttributeContains".

For now I would like to skip it. I am planning to implement "IDL attribute checker" after cleaning up all IDLs, and include the CallWith values check there.
