yeoman/yeoman

Hi, I am trying to rename files using registerTransformStream and gulp, when I use copyTpl it copies both the transformed directory (TestProject) and the original (_name).

    "eslint": "^6.6.0",
    "eslint-config-prettier": "^6.6.0",
    "eslint-config-xo": "^0.27.2",
    "eslint-plugin-prettier": "^3.1.1",

  },
  "engines": {
    "npm": ">= 4.0.0"
  },
  "dependencies": {

    "gulp-rename": "^2.0.0",
    "yeoman-generator": "^2.0.5",
    "yosay": "^2.0.1"
  },

Code is as follows;

const Generator = require("yeoman-generator");
const chalk = require("chalk");
const yosay = require("yosay");
const rename = require("gulp-rename");
const { v4: uuidv4 } = require("uuid");

module.exports = class extends Generator {
  prompting() {
    this.log(
      yosay(
        `Welcome to the sensational ${chalk.red(
          "test"
        )} generator!`
      )
    );

    const prompts = [
      {
        type: "input",
        name: "name",
        message:
          "What is the name of the project? (lowercase & no punctuation only)",
        default: this.appname,
        store: true
      }
    ];

    return this.prompt(prompts).then(props => {
      this.props = props;
    });
  }

  writing() {
    var props = this.props;
    this.registerTransformStream(
      rename(function(path) {
        path.dirname = path.dirname.replace(/(_name)/g, props.name);
      })
    );

    this.fs.copyTpl(
      this.templatePath("**/*"),
      this.destinationPath(""),
      {
        name: props.name.toLowerCase(),
      },
      {},
      { globOptions: { ignore: "_name" } }
    );

    this.log.writeln('\n→ WRITING COMPLETED');
  }

  end() {
    this.log.writeln('\n→ SCAFFOLD COMPLETED');
  }
};

Any ideas how I either remove or exclude the original "_name" dir?
