Add keywords and npm_install prompts, two helpers

[gamtiq]

Hello,

I have added:

• two built-in prompts: keywords and npm_install
• prompt.sanitizeYesNo to convert yes/no answers into boolean values
• init.runNpmInstall to run npm install command
• basic support for github_user key in defaults.json
• support for project’s name as default repository name

Thanks for the PR @gamtiq! Give us some time to test and give feedback.

Hey @gamtiq sorry for the slow response. Just tested this and this seems cool. One thing, would it be better to have init.runNpmInstall(props.npm_install); and leave the done to the template? runNpmInstall might not be the final step in the scaffolding.

Let me know if you wanna update this and I will reopen.

Hello @vladikoff,

Do you mean that:

1. runNpmInstall should have the following signature: init.runNpmInstall(required, done) where both parameters are optional?
2. required parameter should not have true as default value? If so, I can change the implementation.

Yea so we should be able to use init.runNpmInstall() and that would by default run npm install. And also use it this way:

init.runNpmInstall(props.npm_install)
somethingElse()
done()

[gamtiq]

I have made the change. Now it is possible to use runNpmInstall as you wrote:

init.runNpmInstall(props.npm_install)
somethingElse()
done()

Or by this way:

init.runNpmInstall(props.npm_install, function() {
    // The following code will be run in any case but after finishing of "npm install" if props.npm_install is true
    somethingElse();
    done();
});
