Release Notes

tj/commander.js (commander)

v14.0.2

Compare Source

Changed

• improve negative number auto-detection test ([#​2428])
• update (dev) dependencies

v14.0.1

Compare Source

Fixed

• broken markdown link in README ([#​2369])

Changed

• improve code readability by using optional chaining ([#​2394])
• use more idiomatic code with object spread instead of Object.assign() ([#​2395])
• improve code readability using string.endsWith() instead of string.slice() ([#​2396])
• refactor .parseOptions() to process args array in-place ([#​2409])
• change private variadic support routines from ._concatValue() to ._collectValue() (change code from array.concat() to array.push()) ([#​2410])
• update (dev) dependencies

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');

v12.1.0

Compare Source

Added

• auto-detect special node flags node --eval and node --print when call .parse() with no arguments ([#​2164])

Changed

• prefix require of Node.js core modules with node: ([#​2170])
• format source files with Prettier ([#​2180])
• switch from StandardJS to directly calling ESLint for linting ([#​2153])
• extend security support for previous major version of Commander ([#​2150])

Removed

• removed unimplemented Option.fullDescription from TypeScript definition ([#​2191])

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
