How to install vipergen ?

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

sudo gem install vipergen

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

How to generate a VIPER module with a given name?

You have just to execute the following command

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

Another example:

vipergen generate MySecondViperModule --path=~/myproject/shared --author='My Name' --company='My Company' --template='existing_template' --language=swift

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

How can I try the demo project?

  1. Clone the repo git clone https://github.com/pepibumur/viper-module-generator.git
  2. Move into the repo folder and update the git submodules git submodule update --init
  3. In the folder VIPERGenDemo install the pods pod install
  4. Open the project from the VIPERGenDemo.xcworkspace file
  5. Enjoy it!

Developer tips

Update the gem

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 vipergen.gemspec
gem install vipergen-0.1.gem
gem push vipergen-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/)

Add a new template

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 both languages, Swift and Objective-C (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: pepibumur@gmail.com
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.
