-* `parseExpectedArgs` is now private ([#1149])
+### Added
-### Migration Tips
+- `.enablePositionalOptions()` to let program and subcommand reuse same option ([#1427])
+- `.passThroughOptions()` to pass options through to other programs without needing `--` ([#1427])
+- `.allowExcessArguments(false)` to show an error message if there are too many command-arguments on command line for the action handler ([#1409])
+- `.configureOutput()` to modify use of stdout and stderr or customise display of errors ([#1387])
+- use `.addHelpText()` to add text before or after the built-in help, for just current command or also for all subcommands ([#1296])
+- enhance Option class ([#1331])
+ - allow hiding options from help
+ - allow restricting option arguments to a list of choices
+ - allow setting how default value is shown in help
+- `.createOption()` to support subclassing of automatically created options (like `.createCommand()`) ([#1380])
+- refactor the code generating the help into a separate public Help class ([#1365])
+ - support sorting subcommands and options in help
+ - support specifying wrap width (columns)
+ - allow subclassing Help class
+ - allow configuring Help class without subclassing
-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.
+### Changed
-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.
+- *Breaking:* options are stored safely by default, not as properties on the command ([#1409])
+ - this especially affects accessing options on program, use `program.opts()`
+ - revert behaviour with `.storeOptionsAsProperties()`
+- *Breaking:* action handlers are passed options and command separately ([#1409])
+- deprecated callback parameter to `.help()` and `.outputHelp()` (removed from README) ([#1296])
+- *Breaking:* errors now displayed using `process.stderr.write()` instead of `console.error()`
+- deprecate `.on('--help')` (removed from README) ([#1296])
+- initialise the command description to empty string (previously undefined) ([#1365])
+- document and annotate deprecated routines ([#1349])
-If you use `.command('*')` to add a default command, you may be be able to switch to `isDefault:true` with a named command.
+### Fixed
-## [5.0.0-4] (2020-03-03)
+- wrapping bugs in help ([#1365])
+ - first line of command description was wrapping two characters early
+ - pad width calculation was not including help option and help command
+ - pad width calculation was including hidden options and commands
+- improve backwards compatibility for custom command event listeners ([#1403])
+
+### Deleted
-(Released in 5.0.0)
+- *Breaking:* `.passCommandToAction()` ([#1409])
+ - no longer needed as action handler is passed options and command
+- *Breaking:* "extra arguments" parameter to action handler ([#1409])
+ - if being used to detect excess arguments, there is now an error available by setting `.allowExcessArguments(false)`
-## [5.0.0-3] (2020-02-20)
+### Migration Tips
-(Released in 5.0.0)
+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.
-## [5.0.0-2] (2020-02-10)
+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).
-(Released in 5.0.0)
+**program options**
-## [5.0.0-1] (2020-02-08)
+Use the `.opts()` method to access the options. This is available on any command but is used most with the program.
-(Released in 5.0.0)
+```js
+program.option('-d, --debug');
+program.parse();
+// Old code before Commander 7
+if (program.debug) console.log(`Program name is ${program.name()}`);
+```
-## [5.0.0-0] (2020-02-02)
+```js
+// New code
+const options = program.opts();
+if (options.debug) console.log(`Program name is ${program.name()}`);
+```
-(Released in 5.0.0)
+**action handler**
-## [4.1.1] (2020-02-02)
+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.
-### Fixed
+```js
+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()}`);
+ });
+```
-* TypeScript definition for `.action()` should include Promise for async ([#1157])
+```js
+ // New code
+ .action((filename, options, command)) => {
+ if (options.trace) console.log(`Command name is ${command.name()}`);
+ });
+```
-## [4.1.0] (2020-01-06)
+If you already set `.storeOptionsAsProperties(false)` you may still need to adjust your code.
-### Added
+```js
+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()}`);
+ });
+```
-* two routines to change how option values are handled, and eliminate name clashes with command properties ([#933] [#1102])
- * see storeOptionsAsProperties and passCommandToAction in README
-* `.parseAsync` to use instead of `.parse` if supply async action handlers ([#806] [#1118])
+```js
+ // New code
+ .action((filename, options, command)) => {
+ if (command.opts().trace) console.log(`Command name is ${command.name()}`);
+ });
+```
-### Fixed
+## [7.0.0-2] (2020-12-14)
-* Remove trailing blanks from wrapped help text ([#1096])

+
+### Fixed
+
+- add missing TypeScript definition for `.addHelpCommand()' ([#1375])
+- removed blank line after "Arguments:" in help, to match "Options:" and "Commands:" ([#1360])
### Changed
-* dev: switch tests from Sinon+Should to Jest with major rewrite of tests ([#1035])
-* call default subcommand even when there are unknown options ([#1047])
-* *Breaking* Commander is only officially supported on Node 8 and above, and requires Node 6 ([#1053])
+- update dependencies
-### Fixed
+## [6.1.0] (2020-08-28)
-* *Breaking* keep command object out of program.args when action handler called ([#1048])
- * also, action handler now passed array of unknown arguments
-* complain about unknown options when program argument supplied and action handler ([#1049])
- * this changes parameters to `command:*` event to include unknown arguments
-* removed deprecated `customFds` option from call to `child_process.spawn` ([#1052])
-* rework TypeScript declarations to bring all types into imported namespace ([#1081])
+### Added
-### Migration Tips
+- include URL to relevant section of README for error for potential conflict between Command properties and option values ([#1306])
+- `.combineFlagAndOptionalValue(false)` to ease upgrade path from older versions of Commander ([#1326])
+- allow disabling the built-in help option using `.helpOption(false)` ([#1325])
+- allow just some arguments in `argumentDescription` to `.description()` ([#1323])
-#### Testing for no arguments
+### Changed
-If you were previously using code like:
+- tidy async test and remove lint override ([#1312])
-```js
-if (!program.args.length) ...
-```
+### Fixed
-a partial replacement is:
+- executable subcommand launching when script path not known ([#1322])
-```js
-if (program.rawArgs.length < 3) ...
-```
+## [6.0.0] (2020-07-21)
+
+### Added
-## [4.0.0-1] Prerelease (2019-10-08)
+- add support for variadic options ([#1250])
+- allow options to be added with just a short flag ([#1256])
+ - *Breaking* the option property has same case as flag. e.g. flag `-n` accessed as `opts().n` (previously uppercase)
+- *Breaking* throw an error if there might be a clash between option name and a Command property, with advice on how to resolve ([#1275])
+
+### Fixed
-(Released in 4.0.0)
+- Options which contain -no- in the middle of the option flag should not be treated as negatable. ([#1301])

## Options
Options are defined with the `.option()` method, also serving as documentation for the options. Each option can have a short flag (single character) and a long name, separated by a comma or space or vertical bar ('|').
-The options can be accessed as properties on the Command object. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc. See also optional new behaviour to [avoid name clashes](#avoiding-option-name-clashes).
+The parsed options can be accessed by calling `.opts()` on a `Command` object, and are passed to the action handler.
+You can also use `.getOptionValue()` and `.setOptionValue()` to work with a single option value.
-Multiple short flags may optionally be combined in a single argument following the dash: boolean flags, the last flag may take a value, and the value.
+Multi-word options such as "--template-engine" are camel-cased, becoming `program.opts().templateEngine` etc.
+
+Multiple short flags may optionally be combined in a single argument following the dash: boolean flags, followed by a single option taking a value (possibly followed by the value).
For example `-a -b -p 80` may be written as `-ab -p80` or even `-abp80`.
You can use `--` to indicate the end of the options, and any remaining arguments will be used without being interpreted.
-This is particularly useful for passing options through to another
-command, like: `do -- git --version`.
-Options on the command line are not positional, and can be specified before or after other command arguments.
+By default options on the command line are not positional, and can be specified before or after other arguments.

+For subcommands, you can specify the argument syntax in the call to `.command()` (as shown above). This
+is the only method usable for subcommands implemented using a stand-alone executable, but for other subcommands
+you can instead use the following method.
-You use `.arguments` to specify the arguments for the top-level command, and for subcommands they are usually included in the `.command` call. Angled brackets (e.g. `<required>`) indicate required input. Square brackets (e.g. `[optional]`) indicate optional input.
+To configure a command, you can use `.argument()` to specify each expected command-argument.
+You supply the argument name and an optional description. The argument may be `<required>` or `[optional]`.
+You can specify a default value for an optional command-argument.

+
+- `helpWidth`: specify the wrap width, useful for unit tests
+- `sortSubcommands`: sort the subcommands alphabetically
+- `sortOptions`: sort the options alphabetically
+
+There are methods getting the visible lists of arguments, options, and subcommands. There are methods for formatting the items in the lists, with each item having a _term_ and _description_. Take a look at `.formatHelp()` to see how they are used.

-### Avoiding option name clashes
+### Parsing Configuration
-The original and default behaviour is that the option values are stored
-as properties on the program, and the action handler is passed a
-command object with the options values stored as properties.
-This is very convenient to code, but the downside is possible clashes with
-existing properties of Command.
+If the default parsing does not suit your needs, there are some behaviours to support other usage patterns.
-There are two new routines to change the behaviour, and the default behaviour may change in the future:
+By default program options are recognised before and after subcommands. To only look for program options before subcommands, use `.enablePositionalOptions()`. This lets you use
+an option for a different purpose in subcommands.
-- `storeOptionsAsProperties`: whether to store option values as properties on command object, or store separately (specify false) and access using `.opts()`
-- `passCommandToAction`: whether to pass command to action handler,
-or just the options (specify false)
+Example file: [positional-options.js](./examples/positional-options.js)
-Example file: [storeOptionsAsProperties-action.js](./examples/storeOptionsAsProperties-action.js)
+With positional options, the `-b` is a program option in the first line and a subcommand option in the second line:
-```js
-program
- .storeOptionsAsProperties(false)
- .passCommandToAction(false);
+```sh
+program -b subcommand
+program subcommand -b
+```
-program
- .name('my-program-name')
- .option('-n,--name <name>');
+By default options are recognised before and after command-arguments. To only process options that come
+before the command-arguments, use `.passThroughOptions()`. This lets you pass the arguments and following options through to another program
+without needing to use `--` to end the option processing.
+To use pass through options in a subcommand, the program needs to enable positional options.
-program
- .command('show')
- .option('-a,--action <action>')
- .action((options) => {
- console.log(options.action);
- });
+Example file: [pass-through-options.js](./examples/pass-through-options.js)
-program.parse(process.argv);
+With pass through options, the `--port=80` is a program option in the first line and passed through as a command-argument in the second line:
-const programOptions = program.opts();
-console.log(programOptions.name);
+```sh
+program --port=80 arg
+program arg --port=80
```
-### TypeScript
+By default the option processing shows an error for an unknown option. To have an unknown option treated as an ordinary command-argument and continue looking for options, use `.allowUnknownOption()`. This lets you mix known and unknown options.
-The Commander package includes its TypeScript Definition file.
+By default the argument processing does not display an error for more command-arguments than expected.
+To display an error for excess arguments, use`.allowExcessArguments(false)`.
+
+### Legacy options as properties
+
+Before Commander 7, the option values were stored as properties on the command.
+This was convenient to code but the downside was possible clashes with
+existing properties of `Command`. You can revert to the old behaviour to run unmodified legacy code by using `.storeOptionsAsProperties()`.
