Blockquotes

Simplicity is prerequisite for reliability. — Edsger W. Dijkstra

Callouts

Obsidian-style callouts are supported:

Code

Inline code: const greeting = "Hello, world.";

Code block with a file-name label:

export function greet(name: string): string {
  return `Hello, ${name}!`;
}

console.log(greet("world"));src/utils/greet.ts

Highlight a line ([!code highlight]):

function add(a, b) {
  return a + b; 
}example.js

Diff annotations ([!code ++] / [!code --]):

function sum(numbers: number[]) {
  let total = 0; 
  return numbers.reduce((acc, n) => acc + n, 0); 
}

Word highlight ([!code word:hoicau]):

git clone https://github.com/hoicau/hoicau-index-source.git
