I need to extract the last part of a string like this,
http://development.dest/show/images-345/name/289/
I only need this part 289, I tried using string.match with the next pattern.
string.match(url, "(%d+)(\/)$")
And I get this error in error log,
2017/05/22 20:53:04 [error] 31264#0: *5 failed to load external Lua file
I think the last part of the pattern is wrong, but I don't know how to fix it ((\/)).
