Configuration library for ruby with YAML/JSON/TOML backends with unified object access
% gem install asetus
require 'asetus'
cfg = Asetus.cfg
port = cfg.server.port
user = cfg.auth.user
pw = cfg.auth.password
It tried to detect your software name via caller_locations if no ':name' argument was given. It automatically loads /etc/name/config and ~/.config/name/config and merges them together.
require 'asetus'
asetus = Asetus.new name: 'mykewlapp',
default: {'poop'=>'xyzzy'},
adapter: 'yaml',
usrdir: '/home/app/config/',
sysdir: '/System/config/',
load: false
asetus.default.poop2 = [1, 2, 3, 4]
asetus.default.starship.poopers = 42
asetus.load :user
if asetus.user.empty?
asetus.user = asetus.default
asetus.save :user
end
asetus.load # load+merges cfg, takes argument :default, :system, :user
asetus.cfg # merged default + system + user (merged on load)
asetus.default # default only
asetus.system # system only
asetus.user # user only
- each - iterate all config keys in current level
- has_key?(arg) - check if current level has key arg
- [arg] - fetch arg (useful for non-literal retrieval, instead of using #send)
- key? - all keys have question mark version reserved, checks if key exists+true (true), exists+false (false), not-exists (nil)
- all object class methods
- should I add feature to raise on unconfigured/unset?
- should I always merge to 'cfg' when default/system/config is set?
