  • display error message for unknown subcommand, by default (#432 #1088 #1149)
  • display help for missing subcommand, by default (#1088 #1149)
  • combined short options as single argument may include boolean flags and value flag and value (e.g. -a -b -p 80 can be written as -abp80) (#1145)
  • .parseOption() includes short flag and long flag expansions (#1145)
  • .helpInformation() returns help text as a string, previously a private routine (#1169)

  • TypeScript definition for commands property of Command (#1184)

  Fixed

  • preserve argument order in subcommands (#508 #962 #1138)
  • do not emit command:* for executable subcommands (#809 #1149)
  • action handler called whether or not there are non-option arguments (#1062 #1149)
  • combining option short flag and value in single argument now works for subcommands (#1145)
  • only add implicit help command when it will not conflict with other uses of argument (#1153 #1149)
  • implicit help command works with command aliases (#948 #1149)
  • options are validated whether or not there is an action handler (#1149)

  Changed

  • Breaking .args contains command arguments with just recognised options removed (#1032 #1138)
  • Breaking display error if required argument for command is missing (#995 #1149)
  • tighten TypeScript definition of custom option processing function passed to .option() (#1119)
  • Breaking .allowUnknownOption() (#802 #1138)

    • unknown options included in .args
  • only recognised option short flags and long flags are expanded (e.g. -ab or --foo=bar) (#1145)
  • Breaking .parseOptions() (#1138)
    • args in returned result renamed operands and does not include anything after first unknown option
    • unknown in returned result has arguments after first unknown option including operands, not just options and values

  • refactor Option from prototype to class (#1133)
  • refactor Command from prototype to class (#1159)
  • changes to error handling (#1165)
    • throw for author error, not just display message
    • preflight for variadic error
    • add tips to missing subcommand executable
  • TypeScript fluent return types changed to be more subclass friendly, return this rather than Command (#1180)
  • .parseAsync returns Promise<this> to be consistent with .parse() (#1180)
  • update dependencies

  Removed

  • removed EventEmitter from TypeScript definition for Command, eliminating implicit peer dependency on @types/node (#1146)
  • removed private function normalize (the functionality has been integrated into parseOptions) (#1145)
  • parseExpectedArgs is now private (#1149)

  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.
