ausmetrics — GraphQL query

// Query live ABS + RBA data
{
  consumerPriceIndex(
    start: {year: 2025, month: 1},
    end: {year: 2025, month: 12})
  cashRateTarget(

dirsize — Directory Size CLI

A command-line utility that recursively calculates the total size of a directory, with optional .gitignore support to exclude build artefacts and ignored files.

dthc — proc macro

cf!(
  expr   -> term | expr plus term.
  term   -> factor | term mul factor.
  factor -> ident | lparen expr rparen.
  ident  -> alpha (alpha | digit)*.
  alpha  -> 'a'..='z' | 'A'..='Z'.
  digit  -> '0'..'9'.
)
            

dthc — CFG Transpiler Utilities

A Rust proc macro that takes a context-free grammar as input and parses it into production rule data structures at compile time — the foundation for generating language-specific scanners, parsers, and code generators.

ayu component library — Material Design buttons and tonal colour cards

ayu — Material Design Component Library

A Leptos component showcase styled with Tailwind CSS and based on Material Design. Includes a custom HCT colour space algorithm: given an RGB input it produces tonal variants (lighter/darker) while preserving hue, implemented using nalgebra.

sound-studies — composer thread

// Two voices, cycling pitches across threads
let p1 = *p_iter.next().unwrap() as u8
         + ((idx % 2) * 7) as u8;
let p2 = *p_iter_2.next().unwrap() as u8
         + ((idx % 2) * 7) as u8;
tx.send(NoteOn(p1)).unwrap();
tx.send(NoteOn(p2)).unwrap();
let now = Instant::now();
while now.elapsed() < Duration::from_secs_f32(d1) {}
tx.send(NoteOff(p1)); tx.send(NoteOff(p2));
// → synth (BitSet phases) → cpal output
            

sound-studies — Algorithmic Composition

An experimental multi-threaded algorithmic composition engine. Independent composer threads emit NoteOn/NoteOff messages over MPSC channels to a central synthesis engine that renders audio in real time via the system audio device.
