pliego-css

pliego-css is the supported application facade for PliegoCSS, a utility-first CSS compiler built for Rust applications and PliegoRS. The pc! and pcx! macros validate visible style literals while Rust compiles and return a compact Style handle containing only a semantic StyleId.

use pliego_css::{Style, pc, pcx};

const CARD: Style = pc!("rounded-lg bg-surface p-6");

fn button(active: bool) -> Style {
    pcx!(
        "rounded-md",
        if active { "bg-accent text-white" } else { "bg-transparent text-accent" },
    )
}

Style implements Display and converts into String, so renderers can use it directly as a class attribute. Macro expansion does not write a stylesheet; run pliego-cssc against the same visible sources to emit the matching static CSS.

Custom themes are configured from build.rs with the supported pliego-css-build::theme! entrypoint.

Stability

The supported candidate application surface is Style, StyleId, pc!, and pcx!. The repository is still at its pre-release workspace version and this README is not an announcement that 0.1.0 has been published. The lower-level parser, IR, compiler, theme, and proc-macro crates are lockstep implementation packages.

Installation and syntax references live under docs/getting-started and docs/reference in a release checkout. Repository reachability remains a release gate.
