This implementation is mostly a port of the VSCode version of the
ColorExtractor. It seems reasonable the we should support _at least_
what VSCode does for detecting color swatches from LSP completions.
This implementation could definitely be better perf-wise by writing a
dedicated color parser. I also think it would be neat if, in the future,
Zed handled _more_ color formats — especially wide-gamut colors.
There are a few differences to the regexes in the VSCode implementation
but mainly so simplify the implementation :
- The hex vs rgb/hsl regexes were split into two parts
- The rgb/hsl regexes allow 3 or 4 color components whether hsla/rgba or
not and the parsing implementation accepts/rejects colors as needed
