v12.0.0

Compare Source

Added

• .addHelpOption() as another way of configuring built-in help option ([#​2006])
• .helpCommand() for configuring built-in help command ([#​2087])

Fixed

• Breaking: use non-zero exit code when spawned executable subcommand terminates due to a signal ([#​2023])
• Breaking: check passThroughOptions constraints when using .addCommand and throw if parent command does not have .enablePositionalOptions() enabled ([#​1937])

Changed

• Breaking: Commander 12 requires Node.js v18 or higher ([#​2027])
• Breaking: throw an error if add an option with a flag which is already in use ([#​2055])
• Breaking: throw an error if add a command with name or alias which is already in use ([#​2059])
• Breaking: throw error when calling .storeOptionsAsProperties() after setting an option value ([#​1928])
• replace non-standard JSDoc of @api private with documented @private ([#​1949])
• .addHelpCommand() now takes a Command (passing string or boolean still works as before but deprecated) ([#​2087])
• refactor internal implementation of built-in help option ([#​2006])
• refactor internal implementation of built-in help command ([#​2087])

Deprecated

• .addHelpCommand() passing string or boolean (use .helpCommand() or pass a Command) ([#​2087])

Removed

• Breaking: removed default export of a global Command instance from CommonJS (use the named program export instead) ([#​2017])

Migration Tips

global program

If you are using the deprecated default import of the global Command object, you need to switch to using a named import (or create a new Command).

// const program = require('commander');
const { program } = require('commander');

option and command clashes

A couple of configuration problems now throw an error, which will pick up issues in existing programs:

• adding an option which uses the same flag as a previous option
• adding a command which uses the same name or alias as a previous command

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();

  • pad width calculation was not including help option and help command
  • pad width calculation was including hidden options and commands
• improve backwards compatibility for custom command event listeners ([#​1403])

  • 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()}`);
   });

Migration Tips

If you use .on('command:*') or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.

If you use program.args or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.

If you use .command('*') to add a default command, you may be be able to switch to isDefault:true with a named command.

If you want to continue combining short options with optional values as though they were boolean flags, set combineFlagAndOptionalValue(false)
to expand -fb to -f -b rather than -f b.

• Increment inspector port for spawned subcommands ([#​991])
  • e.g. node --inspect myCommand.js clone

Migration Tips

The custom event for a negated option like --no-foo is option:no-foo (previously option:foo).

program
  .option('--no-foo')
  .on('option:no-foo', () => {
    console.log('removing foo');
  });

When using TypeScript, adding a command does not allow an explicit undefined for an unwanted executable description (e.g
for a command with an action handler).

program
