Support adding dynamic IDL strings to Transformer
This is a pain point I’ve encountered while trying to convert cssstyle to use WebIDL2JS.
I’m currently forced to generate ./src/CSSStyleDeclaration‑properties.webidl at build time, which contains the generated partial interface attributes:
- https://drafts.csswg.org/cssom/#ref-for-cssstyledeclaration④
- https://drafts.csswg.org/cssom/#ref-for-cssstyledeclaration⑤
- https://drafts.csswg.org/cssom/#ref-for-cssstyledeclaration⑥
For reference, Blink just uses a getter/setter rather than implementing each attribute individually: https://source.chromium.org/chromium/chromium/src/+/master:third_party/blink/renderer/core/css/css_style_declaration.idl;l=1;drc=fdd99242518b07d1d48e6f8453cbb7963a27cb6a.
Gecko also has an IDL generation step: see https://searchfox.org/mozilla-central/source/dom/bindings/GenerateCSS2PropertiesWebIDL.py.
Generating IDL at build time, like Gecko, seems like the right approach to me.
I also generate them at build time, but I’d like to skip the writing to disk part.
