YAML फ़ॉर्मेटर और वैलिडेटर - YAML फ़ॉर्मेट ऑनलाइन

// YAML formatting and validation using js-yaml
// Install: npm install js-yaml
const yaml = require('js-yaml');

// Validate YAML
function validateYaml(input) {
  try {
    yaml.load(input);
    return { valid: true };
  } catch (error) {
    return {
      valid: false,
      error: error.reason || error.message,
      line: error.mark ? error.mark.line + 1 : undefined,
      column: error.mark ? error.mark.column + 1 : undefined,
    };
  }
}

// Format/Beautify YAML
function formatYaml(input, options = {}) {
  const { indent = 2, sortKeys = false } = options;
  try {
    const parsed = yaml.load(input);
    const formatted = yaml.dump(parsed, {
      indent,
      sortKeys,
      lineWidth: -1,
      noRefs: true,
    });
    return { success: true, output: formatted };
  } catch (error) {
    return { success: false, error: error.message };
  }
}

// Minify YAML (convert to flow style)
function minifyYaml(input) {
  try {
    const parsed = yaml.load(input);
    const minified = yaml.dump(parsed, {
      flowLevel: 0,
      lineWidth: -1,
      noRefs: true,
    });
    return { success: true, output: minified };
  } catch (error) {
    return { success: false, error: error.message };
  }
}

// Example
const yamlStr = 'name: test\nvalue: 42\nitems:\n  - one\n  - two';
console.log('Valid:', validateYaml(yamlStr));
console.log('Formatted:', formatYaml(yamlStr));
console.log('Minified:', minifyYaml(yamlStr));
