CI Config Generator

Generate config files for continuous integration from templates inside the repository.

Usage

Require generator tasks inside your Rakefile:

# Rakefile
require 'ci_config_generator/tasks'

Given config/database.yml is an ignored file, commit a config/database.yml.ci file and invoke

$ rake ci:config:generate

in continuous integration. The task generates a config/database.yml and interpolates environment variables:

# config/database.yml.ci
test:
  db: "%{DB_NAME}"

$ rake ci:config:generate DB_NAME=test_db

# config/databse.yml
test:
  db: "test_db"

The task fails if files would be overriden. So make sure to clean your repository on each ci run.

Please fork and improve.
