console.log(termstyle.level); // 0, 1, 2, or 3

const info = termstyle.getTerminalInfo();
console.log(info);
// {
//   supportsColor: true,
//   colorLevel: 3,
//   columns: 120,
//   rows: 30
// }

🔧 Advanced Usage

Create Custom Formatter

// Create a custom formatter instance
const myStyle = termstyle.create({ force: true });

// Log formatter
const logger = termstyle.createLogFormatter({
  timestamp: true,
  usePrefix: true
});

console.log(logger.info('Information message'));
console.log(logger.warn('Warning message'));
console.log(logger.error('Error message'));
console.log(logger.debug('Debug message'));

Method Chaining

// Complex chaining
termstyle
  .red
  .bgYellow
  .bold
  .underline
  .italic('Complex styled text');

// Conditional chaining
const productionError = termstyle.conditional(isProduction).red('Production error!');
console.log(productionError);

📊 Performance

TermStyle is optimized for performance:

• Lazy evaluation of styles
• Intelligent caching system
• Minimal overhead
• Zero dependencies

// Efficient for loops
const styled = termstyle.red.bold;
for (let i = 0; i < 1000; i++) {
  console.log(styled(`Item ${i}`));
}
