The scalable code generator that saves you time.

export class ShowHelpError extends Error {
  constructor(message: string) {
    super(message)
    Object.setPrototypeOf(this, ShowHelpError.prototype)
  }
}

export const getNoGeneratorError = () => {
  return new ShowHelpError('please specify a generator.')
}

export const getNoActionError = () => {
  return new ShowHelpError('please specify a generator.')
}
export const getActionNotFoundError = (generator, action) => {
  return new ShowHelpError(`I can't find action '${action}' for generator '${generator}'.

  You can try:
  1. 'hygen init self' to initialize your project, and
  2. 'hygen generator new --name ${generator}' to build the generator you wanted.

export const getNoGeneratorsFoundMessage = () => `No generators or actions found. 

      This means I didn't find a _templates folder right here, 
      or anywhere up the folder tree starting here.

      Here's how to start using Hygen:

      $ hygen init self
      $ hygen with-prompt new --name my-generator

      (edit your generator in _templates/my-generator)

      $ hygen my-generator
