Indentation and formatting
4 spaces instead of tabs. PIL suggests using two spaces, but a programmer looks at code from 4 to 8 hours a day, so it's simpler to distinguish indentation with 4 spaces. Why spaces? Similar representation everywhere.
You can use vim modelines:
-- vim:ts=4 ss=4 sw=4 expandtab
A file should ends w/ one newline symbol, but shouldn't ends w/ blank line (two newline symbols).
Every do/while/for/if/function should indent 4 spaces.
Related ``or``/``and`` in ``if`` must be enclosed in the round brackets (). Example:
-- Good
if (a == true and b == false) or (a == false and b == true) then
<...>
end

-- Bad
if a == true and b == false or a == false and b == true then
<...>
end

-- Good but not explicit
if a ^ b == true then
end
Type conversion
Do not use concatenation to convert to string or addition to convert to number (use ``tostring``/``tonumber`` instead):
-- Bad
local a = 123
a = a .. ''

-- Good
local a = 123
a = tostring(a)

-- Bad
local a = '123'
a = a + 5 -- 128

-- Good
local a = '123'
a = tonumber(a) + 5 -- 128
Try to avoid multiple nested ``if``'s with common body:
-- Good
if (a == true and b == false) or (a == false and b == true) then
do_something()
end

-- Bad
if a == true then
if b == false then
do_something()
end
if b == true then
if a == false then
do_something()
end
end
Avoid multiple concatenations in one statement, use ``string.format`` instead:
-- Bad
function say_greeting(period, name)
local a = "good " .. period .. ", " .. name
end

-- Good
function say_greeting(period, name)
local a = string.format("good %s, %s", period, name)
end

-- Best
local say_greeting_fmt = "good %s, %s"
function say_greeting(period, name)
local a = say_greeting_fmt:format(period, name)
end
Use ``and``/``or`` for default variable values
-- Good
function(input)
input = input or 'default_value'
end

-- Ok but excessive
function(input)
if input == nil then
input = 'default_value'
end
end
``if``'s and return statements:
-- Good
if a == true then
return do_something()
end
do_other_thing()

-- Bad
if a == true then
return do_something()
else
do_other_thing()
end
Using spaces:
Don't use spaces between function name and opening round bracket. Split arguments with one whitespace character:
-- Bad
function name (arg1,arg2,...)
end

-- Good
function name(arg1, arg2, ...)
end
Add a space after comment markers:
while true do -- Inline comment
-- Comment
do_something()
end
--[[
Multiline
comment
]]--
Surrounding operators:
-- Bad
local thing=1
thing = thing-1
thing = thing*1
thing = 'string'..'s'

-- Good
local thing = 1
thing = thing - 1
thing = thing * 1
thing = 'string' .. 's'
Add a space after commas in tables:
-- Bad
local thing = {1,2,3}
thing = {1 , 2 , 3}
thing = {1 ,2 ,3}

-- Good
local thing = {1, 2, 3}
Add a space in map definitions after equals signs and commas:
-- Bad
return {1,2,3,4}
return {
key1 = val1,key2=val2
}

-- Good
return {1, 2, 3, 4}
return {
key1 = val1, key2 = val2,
key3 = val3
}
