Lua 转义多行字符串

Question

Hello I'm wondering if I can escape the [[ and ]] in a mutli line string

example:

s = [[  [[ test ]] ]]

and then if I do

print(test)

I would like the output to be, [[ test ]]

is there anyway to do this?

Answer 1

Lua multiline strings don't just use [[ and ]] ; you can also put as many = between the two [ and ] (it has to be the same number though):

local str = [=====[
 ]] This does nothing
 ]=] not enough =
 ]==========] too many =
]=====] -- This closes the string

Answer 2

s = [=[ [[Hello]] ]=]
print(s)

Output [[Hello]]

Seems to work, but I'm just learning this solution as I research to answer this question so I don't know if there are any caveats.
