Yeoman fails if the generator uses user.github.username mixin

[kyoh86]

• I have an account with public email address which ends with *.dev TLD.
• GitHub may have a bug so I cannot find my account with my public email address.
• Yeoman uses github-username package and it calls GitHub API.
  • source

So now, I cannot use yeoman generators using user.github.username mixin.
I know that it is not issue of Yeoman, but I want Yeoman to be able to get GitHub Username without GitHub access.

Proposal: If an environment variable YEOMAN_GITHUB_USERNAME is set, Yeoman uses it.

Have you tried to update github-username from 3.x to 5.x?
I can upgrade if it works.
A workaround like that should not be implemented at generator side.
You should do something like:

async task() {
  const username = await this.user.github.username().catch( ()=> fallback );
}

It's not problem of the github-username.
GitHub API does not return my account with my correct email.

... I'll try to negotiate with some generator authors...

Do you have this problem with multiples generators?
I fell a env var is not good but adding an option is possible.

yo foo --github-username username

ya, but I'll try. thanks.

If you are willing to provide a PR:

1. You should add an option like:
   

   generator/lib/index.js

   Lines 182 to 186 in ba43e2c

   	this.option('ask-answered', {
   	type: Boolean,
   	description: 'Show prompts for already configured options',
   	default: false
   	});

2. Change user mixing to be able to read the generator:
   

   generator/lib/actions/user.js

   Line 12 in ba43e2c

   const user = module.exports;

   
   to:

const generator = module.exports;
const user = generator.user = {};

3. Update username function to read options:
   

   generator/lib/actions/user.js

   Line 62 in ba43e2c

   user.github.username = () => githubUsername(user.git.email());

   
   To something like:

user.github.username = () => {
  if (generator.options && generator.options.githubUsername) {
    return Promise.resolve(generator.options.githubUsername);
  }
  return githubUsername(user.git.email());
}

4. Change user mixin load:
   

   generator/lib/index.js

   Line 1502 in ba43e2c

   Generator.prototype.user = require('./actions/user');

   
   to

_.extend(Generator.prototype, require('./actions/user'));

5. The missing part: provide test case.
