syntax roles

a syntax role is what a piece of code is (a function, a keyword, a comment, a json key) and the color and style it gets. neovim, zed and vs code share one table of roles, SYNTAX in tools/build.py, so a function is blue in all three. this is that table, read from the script when the site is built.

keywords

rime splits keywords by kind instead of painting them one color: declarations are violet, loops yellow, conditionals bold rose, and returns and exceptions rose. the neovim page shows how to make them one color again.

where the editors differ

role names follow neovim's treesitter captures. each port maps its own scope names onto them.
zed puts if, for, return and try into one keyword.control capture, so those share the rose color.
in vs code, typescript and javascript give return, await and yield the same scope, so all three are rose.
neovim's styles option restyles a group of roles at once, so every role in a group carries the group's default style.
