LunaLua style guide

Whitespace

function foo(x, y) -- Spaces between arguments
	-- Indent with tabs. Comments should match indentation.
	local myVar    = 1 --Optionally align. If aligning, use spaces.
	local otherVar = 2

	local someTbl = {
		"tables split across",
		"multiple lines should",
		"look like this"
	}
	print(#someTbl) --No spaces after unary operators.
	return x + myVar --Spaces between binary operators.
end

Comments

--------------------
-- SECTION HEADER --
--------------------

-- Prose comments on their own line should have a space after the --.
local x --This is optional for end-of-line comments, though these should always have space before the --.
-- Multi-line comments should generally still use line comment syntax

--- LDoc-compatible function description.
-- Optional additional description lines.
-- @param foo first parameter
-- @param bar second parameter
function doAThing(foo, bar)
	return foo + bar
end

Miscellaneous

• Semicolons are discouraged.
  • If using semicolons in a file, use consistently throughout entire file.
