Skip to content Added
- simpler ECMAScript import (#1589)
- Option.preset() allows specifying value/arg for option when used without option-argument (especially optional, but also boolean option) (#1652)
.executableDir() for custom search for subcommands (#1571)- throw with helpful message if pass
Option to .option() or .requiredOption() (#1655)
- .
error() for generating errors from client code just like Commander generated errors, with support for .configureOutput (), .exitOverride(), and .showHelpAfterError() (#1675)
.optsWithGlobals() to return merged local and global options (#1671)
Changed
- Breaking: Commander 9 requires Node.js v12.20.0 or higher
- update package-lock.json to lockfile@2 format (#1659)
showSuggestionAfterError is now on by default (#1657)- Breaking: default value specified for boolean option now always used as default value (see .preset() to match some previous behaviours) (#1652)
- default value for boolean option only shown in help if true/false (#1652)
- use command name as prefix for subcommand stand-alone executable name (with fallback to script name for backwards compatibility) (#1571)
- allow absolute path with
executableFile (#1571)
- removed restriction that nested subcommands must specify
executableFile (#1571)
- TypeScript: allow passing readonly string array to
.choices() (#1667)
- TypeScript: allow passing readonly string array to
.parse(), .parseAsync(), .aliases() (#1669)
Fixed
- option with optional argument not supplied on command line now works when option already has a value, whether from default value or from previous arguments (#1652)
Removed
- Breaking: removed internal fallback to
require.main.filename when script not known from arguments passed to .parse()
(can supply details using .name(), and .executableDir() or executableFile) (#1571)
