in HOME/path_test/ I have:
load_test.rb:
require 'yaml'
cnf = YAML::load(File.open('config.yml'))
puts cnf['Hello']
config.yml:
Hello: world!!!
when in HOME/path_test/ I get as expected:
-bash-3.2$ ruby load_test.rb
world!!!
when in HOME/ (cd ..) I get
-bash-3.2$ ruby path_test/load_test.rb
path_test/load_test.rb:3:in `initialize': No such file or directory - config.yml (Errno::ENOENT)
from path_test/load_test.rb:3:in `open'
from path_test/load_test.rb:3:in `<main>'
Which is correct behavior, but not what I had wished for :)
Is there a way to load the .yml file relative to the source file, and not relative to the current working DIR??
Solution (load_Test.rb):
require 'yaml'
fn = File.dirname(File.expand_path(__FILE__)) + '/config.yml'
cnf = YAML::load(File.open(fn))
puts cnf['Hello']
You should get path of the current file by:
cnf = YAML::load_file(File.join(File.dirname(File.expand_path(__FILE__)), 'config.yml'))
EDIT:
Since Ruby 2.0 you can simplify that and use:
cnf = YAML::load_file(File.join(__dir__, 'config.yml'))
