rux-style

Rux styling: literal CSS, parsed with lightningcss, cascaded onto the template tree.

Rux's fourth law is that the CSS in a .rux file is real CSS rather than a lookalike dialect, so this crate parses it with the same engine a browser toolchain would, then matches the rules against the template with its own small selector engine and applies the cascade. Specificity and source order resolve conflicts exactly as they do in CSS. Selector support covers tag, .class, #id, [role="..."], compound selectors such as view.card, and all four combinators. The output is a styled node tree for rux-layout.

Internal to Rux

This is one crate of the Rux workspace. It is published so the toolchain builds from crates.io, not as a library to depend on: it makes no stability promise of its own and its API moves whenever the runtime needs it to. The supported entry point is ruxlang.

cargo install ruxlang     # installs a `rux` command

rux run app.rux
