## [5.1.0] (2020-04-25)
### Added
- support for multiple command aliases, the first of which is shown in the auto-generated help ([#531], [#1236])
- configuration support in `addCommand()` for `hidden` and `isDefault` ([#1232])
### Fixed
- omit masked help flags from the displayed help ([#645], [#1247])
- remove old short help flag when change help flags using `helpOption` ([#1248])
### Changed
- remove use of `arguments` to improve auto-generated help in editors ([#1235])
- rename `.command()` configuration `noHelp` to `hidden` (but not remove old support) ([#1232])
- improvements to documentation
- update dependencies
- update tested versions of node
- eliminate lint errors in TypeScript ([#1208])
## [5.0.0] (2020-03-14)
### Added
* support for nested commands with action-handlers ([#1] [#764] [#1149])
* `.addCommand()` for adding a separately configured command ([#764] [#1149])
* allow a non-executable to be set as the default command ([#742] [#1149])
* implicit help command when there are subcommands (previously only if executables) ([#1149])
* customise implicit help command with `.addHelpCommand()` ([#1149])
* 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])
* `.parse()` implicitly uses `process.argv` if arguments not specified ([#1172])
* optionally specify where `.parse()` arguments "from", if not following node conventions ([#512] [#1172])
* suggest help option along with unknown command error ([#1179])
* TypeScript definition for `commands` property of `Command` ([#1184])
* export `program` property ([#1195])
* `createCommand` factory method to simplify subclassing ([#1191])
### 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 arguments passed to command action handler
* 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
* *Breaking* `.on('command:*', callback)` and other command events passed (changed) results from `.parseOptions`, i.e. operands and unknown ([#1138])
* 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.

This is used in the examples in this README for brevity.
```js
const program = require('commander');
const { program } = require('commander');
program.version('0.0.1');
```
For larger programs which may use commander in multiple ways, including unit testing, it is better to create a local Command object to use.
```js
const commander = require('commander');
const program = new commander.Command();
const { Command } = require('commander');
const program = new Command();
program.version('0.0.1');
```
## 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.
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. Multiple short flags may be combined as a single arg, for example `-abc` is equivalent to `-a -b -c`.

See also optional new behaviour to [avoid name clashes](#avoiding-option-name-clashes).
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.
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.
### Common option types, boolean and value
The two most used option types are a boolean flag, and an option which takes a value (declared using angle brackets). Both are `undefined` unless specified on command line.

const program = require('commander');
const { program } = require('commander');

## Commands
You can specify (sub)commands for your top-level command using `.command`. There are two ways these can be implemented: using an action handler attached to the command, or as a separate executable file (described in more detail later). In the first parameter to `.command` you specify the command name and any command arguments. The arguments may be `<required>` or `[optional]`, and the last argument may also be `variadic...`.
You can specify (sub)commands using `.command()` or `.addCommand()`. There are two ways these can be implemented: using an action handler attached to the command, or as a stand-alone executable file (described in more detail later). The subcommands may be nested ([example](./examples/nestedCommands.js)).
In the first parameter to `.command()` you specify the command name and any command arguments. The arguments may be `<required>` or `[optional]`, and the last argument may also be `variadic...`.
You can use `.addCommand()` to add an already configured subcommand to the program.

## Bits and pieces
### .parse() and .parseAsync()
The first argument to `.parse` is the array of strings to parse. You may omit the parameter to implicitly use `process.argv`.
If the arguments follow different conventions than node you can pass a `from` option in the second parameter:
- 'node': default, `argv[0]` is the application and `argv[1]` is the script being run, with user parameters after that
- 'electron': `argv[1]` varies depending on whether the electron application is packaged
- 'user': all of the arguments from the user
For example:
```js
program.parse(process.argv); // Explicit, node conventions
program.parse(); // Implicit, and auto-detect electron
program.parse(['-f', 'filename'], { from: 'user' });

### createCommand()
This factory function creates a new command. It is exported and may be used instead of using `new`, like:
```js
const { createCommand } = require('commander');
const program = createCommand();
```
`createCommand` is also a method of the Command object, and creates a new command rather than a subcommand. This gets used internally
when creating subcommands using `.command()`, and you may override it to
customise the new subcommand (examples using [subclass](./examples/custom-command-class.js) and [function](./examples/custom-command-function.js)).
### Node options such as `--harmony`
You can enable `--harmony` option in two ways:
- Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. (Note Windows does not support this pattern.)
- Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.
- Use `#! /usr/bin/env node --harmony` in the subcommands scripts. (Note Windows does not support this pattern.)
- Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning subcommand process.
### Node debugging
### Debugging stand-alone executable subcommands
If you are using the node inspector for [debugging](https://nodejs.org/en/docs/guides/debugging-getting-started/) git-style executable (sub)commands using `node --inspect` et al,
An executable subcommand is launched as a separate child process.
If you are using the node inspector for [debugging](https://nodejs.org/en/docs/guides/debugging-getting-started/) executable subcommands using `node --inspect` et al,
the inspector port is incremented by 1 for the spawned subcommand.
If you are using VSCode to debug executable subcommands you need to set the `"autoAttachChildProcesses": true` flag in your launch.json configuration.
