This upgrade came with a number of new lints that needed to be fixed across the code base. Primarily: explicit return types on functions, and explicit visibility modifiers on class members.
Splits out the room locartion parsing from everything else to avoid
one function that fills out different parts of its return struct
depending on its args.
As a first step towards adopting the Compound design system and the new Element Call designs, this pulls in Compound's color tokens and applies them to all existing components. I've tried to choose tokens based on the semantics of where they're used, but in some cases, where the new and old design systems differ in semantics, it was necessary to choose tokens based on their resulting color. These hacks can be removed as we implement more of the new designs.
There were a set of environment variables that we used for custom themes, but Compound has way too many design tokens for that approach to still be a good idea, so I decided to replace them all with a single environment variable that just lets you write arbitrary custom CSS.
This is an Element project (in the vector-im repo) so the Copyright
should be for New Vector: it was incorrectly attributed to the
foundation for some files (and some files were missing headers).
We only ever used the static instance() method to get to the config
object, so just make a static instance that returns the ConfigOptions
directly, throwing an exception if it's not yet initialised. This way
the types can all be non-optional (plus it's shorter).
