Continue your loops in lua
I am so used to the continue word in Java and C that I was surprised to see it absent in lua.
It is however relatively easy to implement it with a good ol’ goto.
Here is a (rather stupid) example. We get a directory listing and we filter out the hidden files (starting with a dot):
local h = io.popen("ls -a") for line in h:lines() do if string.match(line, "^%.") then goto continue end print(line) ::continue:: end h:close()
