Code Features Test

This document tests code-related features in Yank Note: highlighting, running, copying, and wrapping.

Syntax Highlighting

JavaScript

class Calculator {
  constructor() {
    this.result = 0;
  }

  add(value) {
    this.result += value;
    return this;
  }

  multiply(value) {
    this.result *= value;
    return this;
  }

  getResult() {
    return this.result;
  }
}

const calc = new Calculator();
console.log(calc.add(5).multiply(3).getResult()); // 15

TypeScript

interface User {
  id: number;
  name: string;
  email: string;
  roles: string[];
}

function greetUser(user: User): string {
  return `Hello, ${user.name}! You have ${user.roles.length} roles.`;
}

const user: User = {
  id: 1,
  name: "Alice",
  email: "alice@example.com",
  roles: ["admin", "editor"],
};

HTML

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Test Page</title>
  <style>
    body { font-family: sans-serif; }
  </style>
</head>
<body>
  <h1>Hello World</h1>
  <p>This is a test page.</p>
</body>
</html>

Rust

fn fibonacci(n: u32) -> u64 {
    match n {
        0 => 0,
        1 => 1,
        _ => fibonacci(n - 1) + fibonacci(n - 2),
    }
}

fn main() {
    for i in 0..10 {
        println!("fib({}) = {}", i, fibonacci(i));
    }
}

Code Execution (`--run--`)

JavaScript Execution

// --run--
const items = ['apple', 'banana', 'cherry'];
items.forEach((item, index) => {
  console.log(`${index + 1}. ${item}`);
});

JavaScript with HTML Output

// --run-- --output-html--
const colors = ['red', 'green', 'blue'];
const html = colors.map(c =>
  `<span style="color: ${c}; font-weight: bold;">${c}</span>`
).join(' | ');
output = html;

Node.js Execution

// --run-- node
const os = require('os');
console.log('Platform:', os.platform());
console.log('Architecture:', os.arch());
console.log('CPUs:', os.cpus().length);

Python Execution

# --run--
import math

for i in range(1, 6):
    print(f"sqrt({i}) = {math.sqrt(i):.4f}")

Shell Execution

# --run--
echo "Current date: $(date)"
echo "Current directory: $(pwd)"
echo "User: $(whoami)"

Custom Compile Command (C)

// --run-- gcc $tmpFile.c -o $tmpFile.out && $tmpFile.out
#include <stdio.h>

int main() {
    printf("Hello from C!\n");
    for (int i = 1; i <= 5; i++) {
        printf("Count: %d\n", i);
    }
    return 0;
}

Code Copy

All code blocks support a copy button on hover. The language label is displayed in the top-right corner.

Inline code also supports Ctrl/Cmd + Click to copy: npm install yank-note

Code Wrapping

Code wrapping can be enabled with wrap-code: true in front matter or render settings.

This is a very long line that should demonstrate code wrapping behavior when the wrap-code option is enabled. Without wrapping, this line will overflow and require horizontal scrolling. With wrapping enabled, it should break into multiple lines.

Line Numbers

Code blocks automatically display line numbers with a sticky left panel:

// Line 1
// Line 2
// Line 3
// Line 4
// Line 5
// Line 6
// Line 7
// Line 8
// Line 9
// Line 10
// Line 11
// Line 12
// Line 13
// Line 14
// Line 15
