Below you find the basic instructions for an easy installation on Mac, Linux and Windows.
The easiest way is to use Git OSX installer
Git can be also be installed using Homebrew package manager.
To install Homebrew open a terminal and paste the following command:
/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"
Once you have installed Homebrew you can install Git with the following command:
brew install git
Ruby 1.8.7 is preinstalled on Mac OS X 10.6 and later (Snow Leopard and Lion). You just need to:
- Update RubyGems:
sudo gem update -system
- Install bundler:
sudo gem install bundler
If you want to install the latest version of Ruby or if you want to manage multiple versions, the best option is to install RVM (Ruby Version Manager).
Open the terminal and run the following commands:
bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer ) rvm install 1.9.2 rvm use 1.9.2 --default
This will install the latest version 1.9.2 and making it as the default Ruby interpreter
For more information you can check this page.
On Debian Linux (like Ubuntu) you can install Git using the apt package manager. Open a terminal and paste the following code:
sudo apt-get install git-core
On Debian Linux (like Ubuntu) you can use the apt package manager to install Ruby. You need to install Ruby with development tools (-dev):
sudo apt-get install ruby1.9.1-dev
Note that this will install the latest version 1.9.2 and not 1.9.1
Installing Git is pretty easy. Just download and install the package called msysGit.
- Install Ruby 1.8.7 using RubyInstaller. If you are planning to use Ruby on Rails, you should consider the RailsInstaller
- Install Ruby Development Kit needed for some gems
- Install bundler:
gem install bundler
Tip: To make sure the correct Ruby version is used in command line, open command prompt using the “Start command prompt with Ruby” from the Ruby 1.8.7 subfolder in Start-menu
All the examples are contained in a single Git repository that is hosted on GitHub. Here you can find the instructions how to clone the repository and launch the examples.
The first step is to configure your Git with your GitHub account. If you haven't done it yet, create an account at GitHub
You can download the examples by simply cloning this GitHub repository. Open a terminal and run the following code:
git clone firstname.lastname@example.org:aaltowebapps/MobileWebAppsExamples.git
This will create a directory called
MobileWebAppsExamples which contains all the examples in separate subdirectories. If you want you can rename it to something else.
If in the future you need to fetch the changes from the server, you can run the following commands in a terminal:
cd MobileWebAppsExamples git pull
In the directory
MobileWebAppsExamples there is a file called
Gemfile that contains all the additional modules (called gems) that
are required to run the examples.
The first thing is to install Bundler that is tool for managing application's dependencies for Ruby. You can install it by running the following commands in a terminal:
gem install bundler
Once you have install Bundler you can install the additional gems by running the following commands:
cd MobileWebAppsExamples bundle install
Each subdirectory contains a seprate example. Most of examples are based on Sinatra and you can launch the server with the following command:
ruby -rubygems server.rb
Heroku provides a free and convenient way for hosting applications in the cloud. After you sign up for free on their website you can follow these instructions for getting started with Heroku on different platforms. Once you have logged in with you account, you can start to deploy applications by pushing Git repositories. Below there is an example how to deploy the sinatraHelloWorld example.
First we copy all the files of the application that we need to deploy into a separate directory. We start in the parent directory where the examples are located and enter the following commands:
mkdir deploy cd deploy cp ../MobileWebAppsExamples/sinatraHelloWorld/* .
Heroku requires two files for configuring and starting the application: Gemfile and config.ru. We can copy the Gemfile from the examples directory:
cp ../MobileWebAppsExamples/Gemfile .
We can create the file config.ru in this way:
touch config.ru echo "require './server'" >> config.ru echo "run Sinatra::Application" >> config.ru
We create the Git repository and commit all the files
git init git add . git commit -am "First commit"
We create a new Heroku instance with the following command:
The result is:
Creating quiet-day-9893... done, stack is bamboo-mri-1.9.2 http://quiet-day-9893.heroku.com/ | email@example.com:quiet-day-9893.git Git remote heroku added
Heroku has create a new server instance at: http://quiet-day-9893.heroku.com/
Heroku has also created a new Git repository (firstname.lastname@example.org:quiet-day-9893.git) on their servers and automatically configured is as a remote for our local Git repository. We can check that with following command:
git remote -v
The result below shows that we have a new remote called heroku:
heroku email@example.com:quiet-day-9893.git (fetch) heroku firstname.lastname@example.org:quiet-day-9893.git (push)
We can deploy the application by simply pushing the master to heroku:
git push heroku master
The result is the following:
