Create a command with unkown options about deno-cliffy HOT 4 CLOSED

Hi @oganexon,

You can use the .stopEarly() method as descriped in the readme to pass unkown options to your command. If enabled, all options, starting from the first none option argument, will be passed as arguments to the action handler.

Literal arguments won't be passed to the action handler atm, but this feature is in progress.

Great, almost there
If i follow the example I can do:

$ deno run https://deno.land/x/cliffy/examples/command/stop-early.ts -d warning server -p 80
options: { debugLevel: "warning" }
script: server
args: [ "-p", "80" ]

But how can I do:

$ deno run https://deno.land/x/cliffy/examples/command/stop-early.ts --foo warning server -p 80

from deno-cliffy.

This is not possible with .stopEarly(), because .stopEarly() needs to know which options belongs to the command and which to the arguments. You need an argument to separate these options.

In your example, --foo will be interpreted as option from the stop-early.ts command and warning server -p 80 will be passed as arguments because warning is the first none option argument.

There is also another method called .useRawArgs(). If you call this method, all options are interpreted as arguments. But this will also disable the handling of all build in options like --help and --version.

Perfect, I managed to have help and get the args

export class RunCommand extends DefaultCommand {
  public constructor() {
    super();

    this.description(desc)
    .useRawArgs()
    .action((_, ...args) => {
      if (["-h", "--help", "help"].includes(args[0])) {
        Deno.stdout.writeSync(new TextEncoder().encode( this.getHelpCommand().getHelp() ) );
        Deno.exit()
      }
      console.log(args)
    });
  }
}
