How do I access command help inside command itself?

[Souvikns]

I want to print the command level help when the command is run, I used to do something like this in the old version

import { flags} from '@oclif/command';
import Command from '../base';

export class Config extends Command {
  static description = 'access configs'
  static flags = {
    help: flags.help({char: 'h'})
  }

  async run() {
    await this._help();
  }
}

In the new version, I don't think there is this._help() function.

How can I get the same functionality in the new version?

I found this solution that works for me:

async run() {
      await this.config.runCommand("help", [this.id]);
}

From here: https://github.com/oclif/core/blob/main/src/main.ts#L67

@Pavek what I was trying to do was a bit different but thanks to you I figured it out. Firstly I did not have a help command which is because I am not using the help plugin so this does not work but I did something like this and now it works.

    async run(){
        const Help = await loadHelpClass(this.config);
        const help = new Help(this.config)
        help.showHelp(['start', '--help'])
    }

@Souvikns Glad it was helpful. You may also get rid of loadHelpClass as w/o Custom Help it's not very useful:

return Help
