If you want a separator to separate a string:
function separate(str, separator)
separator = tostring(separator) --just in case you're using a number as a separator
local catches = {}
for i in str:gmatch(string.format("[^%s]+", "%"..separator)) do
table.insert(catches, i)
end
return catches
end
print(unpack(separate("1 2 3", " "))) -> 1 2 3
Otherwise, if you don't want to capture all of the non-whitespace characters:
print(string.match("Foo Bar", "%S+")) -> Foo |
