Refactor help option implementation to hold actual Option #2006

Pull Request

The main motivation for this refactor is to potentially simplify future work that uses more Option properties. For example, adding help group to Option like in #1910.

Instead of extending .helpOption() to add parallel features like:

program.helpOption('-s, --support', 'Show help', { helpGroup: 'Demo Options:' });

could instead use same approach as normal options:

program.addHelpOption(new Option('-s, --support', 'Show help').group('Demo Options:'));

(This overlaps with motivation and implementation in #1929.)

Problem

Additions to Option that can be used with .addOption() can't be used with the help option. For example, hiding the help option (#689).

There are an annoying number of help option related properties on Command.

Determining the help option flags does not go through cmd.createOption() so misses some potential custom class behaviour, such as custom flags parsing. (Minor!)

Solution

Store a help Option rather than the necessary deconstructed properties.

Add .addHelpOption() to add author created option, exposing more configuration just like .addOption() does.

ChangeLog

  • Added: .addHelpOption() as another way of configuring built-in help option
  • Changed: refactor internal implementation of built-in help option

I will do another prerelease this weekend with the help command and help option refactor, and then we could perhaps release in a couple of weeks.

| Package | Type | Update | Change |
|---|---|---|---|
| [commander](https://github.com/tj/commander.js) | dependencies | major | [`^11.1.0` -> `^12.0.0`](https://renovatebot.com/diffs/npm/commander/11.1.0/12.0.0) |

### Release Notes

<details>
<summary>tj/commander.js (commander)</summary>

### [`v12.0.0`](https://github.com/tj/commander.js/blob/HEAD/CHANGELOG.md#1200-2024-02-03)

[Compare Source](tj/commander.js@v11.1.0...v12.0.0)

##### Added

-   `.addHelpOption()` as another way of configuring built-in help option (\[[#&#8203;2006](tj/commander.js#2006)])
-   `.helpCommand()` for configuring built-in help command (\[[#&#8203;2087](tj/commander.js#2087)])

##### Fixed

-   *Breaking:* use non-zero exit code when spawned executable subcommand terminates due to a signal (\[[#&#8203;2023](tj/commander.js#2023)])
-   *Breaking:* check `passThroughOptions` constraints when using `.addCommand` and throw if parent command does not have `.enablePositionalOptions()` enabled (\[[#&#8203;1937](tj/commander.js#1937)])

##### Changed

-   *Breaking:* Commander 12 requires Node.js v18 or higher (\[[#&#8203;2027](tj/commander.js#2027)])
-   *Breaking:* throw an error if add an option with a flag which is already in use (\[[#&#8203;2055](tj/commander.js#2055)])
-   *Breaking:* throw an error if add a command with name or alias which is already in use (\[[#&#8203;2059](tj/commander.js#2059)])
-   *Breaking:* throw error when calling `.storeOptionsAsProperties()` after setting an option value (\[[#&#8203;1928](tj/commander.js#1928)])
-   replace non-standard JSDoc of `@api private` with documented `@private` (\[[#&#8203;1949](tj/commander.js#1949)])
-   `.addHelpCommand()` now takes a Command (passing string or boolean still works as before but deprecated) (\[[#&#8203;2087](tj/commander.js#2087)])
-   refactor internal implementation of built-in help option (\[[#&#8203;2006](tj/commander.js#2006)])
-   refactor internal implementation of built-in help command (\[[#&#8203;2087](tj/commander.js#2087)])

##### Deprecated

-   `.addHelpCommand()` passing string or boolean (use `.helpCommand()` or pass a Command) (\[[#&#8203;2087](tj/commander.js#2087)])

##### Removed

-   *Breaking:* removed default export of a global Command instance from CommonJS (use the named `program` export instead) (\[[#&#8203;2017](tj/commander.js#2017)])

##### Migration Tips

**global program**

If you are using the [deprecated](./docs/deprecated.md#default-import-of-global-command-object) default import of the global Command object, you need to switch to using a named import (or create a new `Command`).

```js
// const program = require('commander');
const { program } = require('commander');
```

**option and command clashes**

A couple of configuration problems now throw an error, which will pick up issues in existing programs:

-   adding an option which uses the same flag as a previous option
-   adding a command which uses the same name or alias as a previous command

</details>
