Compare Source

Fixed

• display help when requested, even if there are missing required options [(#​1091)]

v4.0.0

Compare Source

Added

• automatically wrap and indent help descriptions for options and commands ([#​1051])
• .exitOverride() allows override of calls to process.exit for additional error handling and to keep program running ([#​1040])
• support for declaring required options with .requiredOptions() ([#​1071])
• GitHub Actions support ([#​1027])

Fixed

Migration Tips

Testing for no arguments

If you were previously using code like:

if (!program.args.length) ...

a partial replacement is:

if (program.rawArgs.length < 3) ...

v3.0.2

Compare Source

Fixed

• Improve tracking of executable subcommands.

Changed

• update development dependencies

v3.0.1

Compare Source

Added

• .name and .usage to README ([#​1010])
• Table of Contents to README ([#​1010])
• TypeScript definition for executableFile in CommandOptions ([#​1028])

Changed

• consistently use const rather than var in README ([#​1026])

Fixed

• help for sub commands with custom executableFile ([#​1018])

v3.0.0

Compare Source

• Add option to specify executable file name ([#​999])
  • e.g. .command('clone', 'clone description', { executableFile: 'myClone' })
• Change docs for .command to contrast action handler vs git-style executable. ([#​938][#​990])
• Breaking Change TypeScript to use overloaded function for .command. ([#​938][#​990])
• Change to use straight quotes around strings in error messages (like 'this' instead of `this') ([#​915])
• Add TypeScript "reference types" for node ([#​974])
• Add support for hyphen as an option argument in subcommands ([#​697])
• Add support for a short option flag and its value to be concatenated for action handler subcommands ([#​599])
  • e.g. -p 80 can also be supplied as -p80
• Add executable arguments to spawn in win32, for git-style executables ([#​611])
  • e.g. node --harmony myCommand.js clone
• Add parent command as prefix of subcommand in help ([#​980])
• Add optional custom description to .version ([#​963])
  • e.g. program.version('0.0.1', '-v, --vers', 'output the current version')
• Add .helpOption(flags, description) routine to customise help flags and description ([#​963])
  • e.g. .helpOption('-e, --HELP', 'read more information')
• Fix behavior of --no-* options ([#​795])
  • can now define both --foo and --no-foo
  • Breaking custom event listeners: --no-foo on cli now emits option:no-foo (previously option:foo)
  • Breaking default value: defining --no-foo after defining --foo leaves the default value unchanged (previously set it to false)
  • allow boolean default value, such as from environment ([#​987])
• 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
  .command('action1', undefined, { noHelp: true }) // No longer valid
  .command('action2', { noHelp: true }) // Correct
