Configurable option (camel-)casing

[mmkal]

Hi! For trpc-cli, I'd like to support properties like useMCPServer: z.string() nicely. Right now, the only way to get commander to parse an option into program.opts().useMCPServer is to define an option --use-m-c-p-server which is horrible looking.

It'd be nice if I could do something like this:

const option = new Option('--use-mcp-server', {attributeName: 'useMCPServer'})

I'm trying a workaround in trpc-cli by sub-classing Option and overriding attributeName(), but it seems a bit brittle: https://github.com/mmkal/trpc-cli/pull/149/files#diff-a2a171449d862fe29692ce031981047d7ab755ae7f84c707aef80701b3ea0c80R287

Sub-classing Option to override .attributeName() is a reasonable approach.

You can override Command.createOption() to return your custom subclass so that implicitly created options also use your subclass.

---

const option = new Option('--use-mcp-server', {attributeName: 'useMCPServer'})

We use chaining heavily so this approach would look like (say):

const option = new Option('--use-mcp-server').setAttributeName('useMCPServer');

Oh nice, didn't spot createOption. If subclassing like that is considered an ok way to do this, I'm fine with it. Feel free to close unless you want to keep open to track setAttributeName.

Thanks!
