Release Notes

tj/commander.js (commander)

v14.0.0

Compare Source

Added

• support for groups of options and commands in the help using low-level .helpGroup() on Option and Command, and higher-level .optionsGroup() and .commandsGroup() which can be used in chaining way to specify group title for following options/commands ([#​2328])
• support for unescaped negative numbers as option-arguments and command-arguments ([#​2339])
• TypeScript: add parseArg property to Argument class ([#​2359])

Fixed

• remove bogus leading space in help when option has default value but not a description ([#​2348])
• .configureOutput() now makes copy of settings instead of modifying in-place, fixing side-effects ([#​2350])

Changed

• Breaking: Commander 14 requires Node.js v20 or higher
• internal refactor of Help class adding .formatItemList() and .groupItems() methods ([#​2328])

v13.1.0

Compare Source

Added

• support a pair of long option flags to allow a memorable shortened flag, like .option('--ws, --workspace') ([#​2312])

v13.0.0

Compare Source

Added

• support multiple calls to .parse() with default settings ([#​2299])
• add .saveStateBeforeParse() and .restoreStateBeforeParse() for use by subclasses ([#​2299])
• style routines like styleTitle() to add color to help using .configureHelp() or Help subclass ([#​2251])
• color related support in .configureOutput() for getOutHasColors(), getErrHasColors(), and stripColor() ([#​2251])
• Help property for minWidthToWrap ([#​2251])
• Help methods for displayWidth(), boxWrap(), preformatted() et al ([#​2251])

Changed

• Breaking: excess command-arguments cause an error by default, see migration tips ([#​2223])
• Breaking: throw during Option construction for unsupported option flags, like multiple characters after single - ([#​2270])
  • note: support for dual long option flags added in Commander 13.1
• Breaking: throw on multiple calls to .parse() if storeOptionsAsProperties: true ([#​2299])
• TypeScript: include implicit this in parameters for action handler callback ([#​2197])

Deleted

• Breaking: Help.wrap() refactored into formatItem() and boxWrap() ([#​2251])

Migration Tips

Excess command-arguments

It is now an error for the user to specify more command-arguments than are expected. (allowExcessArguments is now false by default.)

Old code:

program.option('-p, --port <number>', 'port number');
program.action((options) => {
  console.log(program.args);
});

Now shows an error:

$ node example.js a b c
error: too many arguments. Expected 0 arguments but got 3.

You can declare the expected arguments. The help will then be more accurate too. Note that declaring new arguments will change what is passed to the action handler.

program.option('-p, --port <number>', 'port number');
program.argument('[args...]', 'remote command and arguments'); // expecting zero or more arguments
program.action((args, options) => {
  console.log(args);
});

Or you could suppress the error, useful for minimising changes in legacy code.

program.option('-p, --port', 'port number');
program.allowExcessArguments();
program.action((options) => {
  console.log(program.args);
});

Stricter option flag parsing

Commander now throws an error for option flag combinations that are not supported. In particular, a short flag with multiple characters is now an error.

program.option('-ws, --workspace'); // throws error

A short option has a single character:

program.option('-w, --workspace');

Or from Commander 13.1 you can have an extra long flag instead of a short flag to allow a more memorable shortcut for the full name:

program.option('--ws, --workspace');

v12.0.0

Compare Source

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])

• 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();

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()}`);
   });
