Access config file from any directory?

I am making a command line tool and I am using yaml to make a config file. But right now I can only access the tool when I am in the same directory as that of myprogram.yml.

private

CONFIG_FILE = 'myprogram.yml'

def write_config
  config = {}
  config['username']=@username
  config['password']=@password
  File.open(CONFIG_FILE, 'w') do |f|
    f.write config.to_yaml
  end
end

def read_config
  config = YAML.load_file(CONFIG_FILE)
  @username = config['username']
  @password = config['password']
end

How can I make this file to be accessed from any directory on my computer?

You'll want to give the absolute directory of the myprogram.yml file. Right now it will look in the directory where you are executing the ruby script from. By making it absolute, the script can run anywhere and know where to find the config file.

Example:

private

CONFIG_FILE = '/Users/myuser/config/myprogram.yml'

def write_config
  config = {}
  config['username']=@username
  config['password']=@password
  File.open(CONFIG_FILE, 'w') do |f|
    f.write config.to_yaml
  end
end

def read_config
  config = YAML.load_file(CONFIG_FILE)
  @username = config['username']
  @password = config['password']
end
