Adding a new IDL file
Serenity's build system does a lot of work of turning the IDL from a Web spec into code, but there are a few things you'll need to do yourself.
For the sake of example, let's say you're wanting to add the HTMLDetailsElement
.
- Create
LibWeb/HTML/HTMLDetailsElement.idl
with the contents of the IDL section of the spec. In this case, that would be:
[Exposed=Window]
interface HTMLDetailsElement : HTMLElement {
[HTMLConstructor] constructor();
[CEReactions] attribute boolean open;
};
- If the IDL refers to other IDL types, you need to import those. For example,
CSSRule
has an attribute that returns aCSSStyleSheet
, so that needs to be imported:
#import <CSS/CSSStyleSheet.idl>
interface CSSRule {
readonly attribute CSSStyleSheet? parentStyleSheet;
};
-
Add a
libweb_js_bindings(HTML/HTMLDetailsElement)
call toLibWeb/idl_files.cmake
-
Forward declare the generated class in
LibWeb/Forward.h
:HTMLDetailsElement
in its namespace.
-
If your type isn't an Event or Element, you will need to add it to
is_platform_object()
so that it can be accepted as an IDL parameter, attribute or return type.
