Create alias for subcommand

[fu050409]

Describe the feature

Hey! Sometimes we faced with a situation that we should create alias for subcommands. For example, pnpm i and pnpm install. The subcommand named i and subcommand named install is the same command.

The solution now is to create two subcommands with same value, like:

subCommands: { i: installCommand, install: installCommand }

But this looks not so elegant. Can we support alias parameter for defineCommand? I can work for my issue.

Additional information

• Would you be willing to help implement this feature?

[zuixinwang]

it's a good idea, but the help output should also be considered

[naruko-hstk]

maybe let help output like this?

install    Install packages.(alias:i)

[ratiofu]

Or perhaps

install, i    Install packages

[BlueBazze]

Shouldn't it just keep the standard of the | separator like in the usage display?
npx nuxt -> USAGE nuxi [OPTIONS] [COMMAND] add|add-template|analyze|build|cleanup|_dev|dev|devtools|generate|info|init|module|prepare|preview|start|test|typecheck|upgrade|complete

Meaning the alias shown under commands like:

install|i    Install packages

As an example with nuxt cli

 add|a    Add Nuxt modules
 dev|d    Run Nuxt development server
test|t    Run tests   

Perhaps with either differently colored separator, or spacing to differentiate between the commands.
