Split A Sting In Lua

Heads-Up

there's a better function to use in:

id: 2xgl9090

This works, but the other is more robust

Splitting a string in lua can be done by matching everything except for the separator in a `.gmatch()`` capture group like this:

Code

local line = "alfa bravo charlie"

local words = {}
for word in string.gmatch(line, "%S+") do
    table.insert(words, word)
end

print(words[1])
print(words[2])
print(words[3])

Results

alfa
bravo
charlie

Another approach

Code

function mysplit (inputstr, sep)
        if sep == nil then
                sep = "%s"
        end
        local t={}
        for str in string.gmatch(inputstr, "([^"..sep.."]+)") do
                table.insert(t, str)
        end
        return t
end

input_string = 'this is it'

base_table = mysplit(input_string, " ")

for i=2, #base_table do
        print(base_table[i])
end
