maud_extensions

Proc macros to simplify Maud views with inline CSS, JS, and font helpers.

Install

cargo add maud-extensions

Quick start

use maud_extensions::{css, js};

maud::html! {
    div class="card" {
        (css! {
            me { padding: 8px; border: 1px solid #ddd; }
            me em { color: #c00; }
        })
        p { "Inline CSS and JS" }
        (js! {
            me().class_add("ready");
        })
    }
}

Macro overview

css! { ... } or css!("...")
- Emits a <style> block with raw CSS.
- Validates CSS using cssparser.
js! { ... } or js!("...")
- Emits a <script> block with raw JS.
- Validates JavaScript using swc_ecma_parser.
inline_css! { ... } and inline_js! { ... }
- Generate fn css() -> maud::Markup / fn js() -> maud::Markup helpers.
font_face! and font_faces!
- Inline font-face CSS as data URLs.

CSS scoping pattern

These macros are often paired with a tiny JS scoper like css-scope-inline. It rewrites selectors like me { ... } to a unique class on the parent element.

Example:

(css! {
    me { border: 1px dashed var(--accent); }
    me em { font-style: normal; }
})

Inline JS helpers

The JS macro is format-preserving but may add spacing for token safety. It still emits valid JavaScript. The examples use surreal for the me() helper, but any inline script works.

(js! {
    me().class_add("pinged");
})

Font helpers

font_face! and font_faces! embed font files as base64 data URLs. Because this macro expands at the call site, the consuming crate must include base64 if you use these macros.

use maud_extensions::font_face;

maud::html! {
    (font_face!("static/fonts/JetBrainsMono.woff2", "JetBrains Mono"))
}
