Removed

• Breaking: TypeScript declaration for default export of global Command object ([#​1520])

Migration Tips

If you have a simple program without an action handler, you will now get an error if
there are missing command-arguments.

program
  .option('-d, --debug')
  .arguments('<file>');
program.parse();

$ node trivial.js 
error: missing required argument 'file'

If you want to show the help in this situation, you could check the arguments before parsing:

if (process.argv.length === 2)
  program.help();
program.parse();

Or, you might choose to show the help after any user error:

program.showHelpAfterError();

  • no longer needed as action handler is passed options and command
• Breaking: "extra arguments" parameter to action handler ([#​1409])
  • if being used to detect excess arguments, there is now an error available by setting .allowExcessArguments(false)

Migration Tips

The biggest change is the parsed option values. Previously the options were stored by default as properties on the command object, and now the options are stored separately.

If you wish to restore the old behaviour and get running quickly you can call .storeOptionsAsProperties().
To allow you to move to the new code patterns incrementally, the action handler will be passed the command twice,
to match the new "options" and "command" parameters (see below).

program options

Use the .opts() method to access the options. This is available on any command but is used most with the program.

program.option('-d, --debug');
program.parse();
// Old code before Commander 7
if (program.debug) console.log(`Program name is ${program.name()}`);

// New code
const options = program.opts();
if (options.debug) console.log(`Program name is ${program.name()}`);

action handler

The action handler gets passed a parameter for each command-argument you declared. Previously by default the next parameter was the command object with the options as properties. Now the next two parameters are instead the options and the command. If you
only accessed the options there may be no code changes required.

program
  .command('compress <filename>')
  .option('-t, --trace')
  // Old code before Commander 7
  .action((filename, cmd)) => {
    if (cmd.trace) console.log(`Command name is ${cmd.name()}`);
  });

  // New code
  .action((filename, options, command)) => {
    if (options.trace) console.log(`Command name is ${command.name()}`);
  });

If you already set .storeOptionsAsProperties(false) you may still need to adjust your code.

program
  .command('compress <filename>')
  .storeOptionsAsProperties(false)
  .option('-t, --trace')
  // Old code before Commander 7
  .action((filename, command)) => {
    if (command.opts().trace) console.log(`Command name is ${command.name()}`);
  });

   // New code
   .action((filename, options, command)) => {
      if (command.opts().trace) console.log(`Command name is ${command.name()}`);
   });
