You can install it easily as using the gem. With ruby installed in your OSX execute:

sudo gem install vipergeng

If everything were right, you should have now the vipergeng command available in your system console

You have just to execute the following command

--path 지정을 하지 않으면 현재 폴더에 생성.

vipergeng generate MyFirstViperModule --path=~/myproject/shared

or

vipergeng g MyFirstViperModule

Another example:

vipergeng generate MySecondViperModule --path=~/myproject/shared --author='My Name' --company='My Company' --project='project name --base=MyBaseViewController'

And then the files structure will be automatically created. Don't forget to add this folder to your project dragging it into the XCode/Appcode inspector

When the gem is updated it has to be reported to the gem repository. I followed this tutorial http://amaras-tech.co.uk/article/43/Creating_executable_gems that basically says that once you have your gem ready execute:

gem build vipergeng.gemspec
gem install vipergeng-0.1.gem
gem push vipergeng-0.1.gem

Then you'll be asked for your credentials in order to make the update in the repo (http://guides.rubygems.org/publishing/) ``

Are you interested in VIPER and you would like to contribute with this gem adding new templates? Feel free to do it. It's pretty easy. You've just to:

• Create a folder inside templates with the name of your template
• You'll have to create inside the templates in Swift (get inspired from existing templates)
• Use the word VIPER where you want the name to be replaced in.
• Remember to add the file viperspec.yml with the description of your template as below:

author: pepi
author_email: [email protected]
template_description: Default template with the simplest structure using VIPER
updated_at: 2014-08-24

• Report it as a PR in this repo updating the gem version in Gemspec.
