Strings

String Literals

Nebra supports all Lua string forms:

local a = "double quoted"
local b = 'single quoted'
local c = [[long bracket string
spans multiple lines]]
local d = [==[nested brackets]==]

When string_interpolation = true in config, backtick strings support embedded expressions:

local name = "Alice"
local age = 30
local msg = `Hello, {name}! You are {age} years old.`

Compiles to:

local msg = "Hello, " .. tostring(name) .. "! You are " .. tostring(age) .. " years old."

Any expression can be embedded:

local result = `2 + 2 = {2 + 2}`
local info = `Length: {#items}, First: {items[1]}`

local escaped = `Use \{braces\} literally`
local backtick = `Use \` for backticks`

The .. operator always works for concatenation:

local greeting = "Hello" .. " " .. "World"

With concat_operator = "+" in config, + also works:

local greeting = "Hello" + " " + "World"

This compiles to a helper function that handles both string and number addition.
