LibWeb: Port CharacterData from DeprecatedString to String The existing implementation has some pre-existing issues where it is incorrectly assumes that byte offsets are given through the IDL instead of UTF-16 code units. While making these changes, leave some FIXMEs for that. 2023-09-07 21:36:05 +12:00			`[Exposed=Window]`
LibWeb: Add CharacterData and Text IDL interfaces 2020-08-03 20:50:45 +02:00			`interface CharacterData : Node {`
LibWeb: Add [LegacyNullToEmptyString] to CharacterData.data See https://dom.spec.whatwg.org/#characterdata 2021-09-06 01:01:53 +01:00			`[LegacyNullToEmptyString] attribute DOMString data;`
LibWeb: Use UTF-16 code unit offsets and lengths in CharacterData We were previously assuming that the input offsets and lengths were all in raw byte offsets into a UTF-8 string. While internally our String representation may be in UTF-8 from the external world it is seen as UTF-16, with code unit offsets passed through, and used as the returned length. Beforehand, the included test included in this commit would crash ladybird (and otherwise return wrong values). The implementation here is very inefficient, I am sure there is a much smarter way to write it so that we would not need a conversion from UTF-8 to a UTF-16 string (and then back again). Fixes: #20971 2023-12-22 20:41:34 +13:00			`[ImplementedAs=length_in_utf16_code_units] readonly attribute unsigned long length;`

LibWeb: Add CharacterData.substringData(offset, count) 2022-03-21 17:20:42 +01:00			`DOMString substringData(unsigned long offset, unsigned long count);`

			`undefined insertData(unsigned long offset, DOMString data);`
			`undefined deleteData(unsigned long offset, unsigned long count);`
LibWeb: Add CharacterData.replaceData(offset, count, data) Note that we don't queue mutation records or update live ranges yet, I've left those as FIXMEs. 2022-03-21 18:05:20 +01:00			`undefined replaceData(unsigned long offset, unsigned long count, DOMString data);`

LibWeb: Expect IDL namespace to end with semicolon From the Web IDL spec: https://heycam.github.io/webidl/#prod-Namespace Namespace :: namespace identifier { NamespaceMembers } ; 2020-12-09 21:26:42 +00:00			`};`
LibWeb: Resolve circular IDL imports These circular imports led to the generator silently failing to generate the required methods/properties. 2022-07-30 11:31:17 +01:00
