regexgolf for mobile vs desktop browser's User-Agents
Program (based off Peter Norvig's code) to generate the shortest regular expression to match a mobile browser's User-Agent.
The shortest regular expression that can match a mobile browser's User-Agent, generated from two lists: one of known mobile user-agents, and one of known non-mobile user-agents.
Dataset based on available mobile browsers in Chrome's emulation: https://developer.chrome.com/devtools/docs/mobile-emulation
