Hey can someone help me with string.match, how would i compare one string to another,
EXAMPLE

s = ‘hey’
s2 = ‘Hey’

How would i compare both strings if they have the same text, even if its capitalized.

local s = "hey"
local s2 = "Hey"

if s == s2 then -- no 'strcmp' like in C
    print("the strings are equal")
else
    print("the strings aren't equal :(")
end

these two links should be very helpful

It’s sort of like what @ElusiveEpix said, but different. You will need to use string.lower() or "string":lower()

local s = "hey"
local s2 = "Hey"

print(s:lower() == s2:lower()) --will print true.

there’s actually case insensitive matching in the manual.

function nocase (s)
  s = string.gsub(s, "%a", function (c)
        return string.format("[%s%s]", string.lower(c), string.upper(c))
      end)
  return s
end

print(nocase("Hi there!"))
-->  [hH][iI] [tT][hH][eE][rR][eE]!

this gives a case insensitive pattern for string.match.
