For normal flag parsing, * rely on Commander.js which handles this automatically. * * @param flagName The flag name including dashes (e.g., '--settings') * @param argv Optional argv array to parse (defaults to process.argv) * @returns The value if found, undefined otherwise */export function eagerParseCliFlag( flagName: string, argv: string[] = process.argv,): string | undefined { for (let i = 0; i < argv.length; i++) { const arg = argv[i] // Handle --flag=value syntax if (arg?.startsWith(`${flagName}=`)) { return arg.slice(flagName.length + 1) } // Handle --flag value syntax if (arg === flagName && i + 1 < argv.length) { return argv[i + 1] } } return undefined}
/** * Handle the standard Unix `--` separator convention in CLI arguments. * * When using Commander.js with `.passThroughOptions()`, the `--` separator * is passed through as a positional argument rather than being consumed. * This means when a user runs: * `cmd --opt value name -- subcmd --flag arg` * * Commander parses it as: * positional1 = "name", positional2 = "--", rest = ["subcmd", "--flag", "arg"] * * This function corrects the parsing by extracting the actual command from * the rest array when the positional is `--`. * * @param commandOrValue - The parsed positional that may be "--" * @param args - The remaining arguments array * @returns Object with corrected command and args */export function extractArgsAfterDoubleDash( commandOrValue: string, args: string[] = [],): { command: string; args: string[] } { if (commandOrValue === '--' && args.length > 0) { return { command: args[0]!, args: args.slice(1), } } return { command: commandOrValue, args }}
