| local function matches(input, pattern) | |
| local index = 1 | |
| return function() | |
| local match = input:match(pattern, index) | |
| if match then | |
| index = index + match:len() + 1 | |
| return match | |
| else | |
| return nil | |
| end |
| global | |
| stats socket ipv4@127.0.0.1:9999 level admin | |
| stats socket /var/run/hapee-lb.sock mode 666 level admin | |
| stats timeout 2m |
