We've asked a similar question a while ago, and the best we could come up
with is a hack to run `heroku config -s`.
config = {}
config_output = `heroku config -s#{app_param}`.chomp
if ($?.to_i != 0)
raise "error running heroku config: #{$?}"
$stderr.puts config_output
end
config_output.each_line do |line|
parts = line.split("=", 2)
raise "invalid line #{line}" if (parts.size != 2)
config[parts[0].strip] = parts[1].strip
end
config
