Examples

-- load library
local table = require "luatable"
-- create a normal table
local t = { 1, 2, 2, 3, -4, 5 }
-- remove negative values
t = table.accept(t, table.positive)
-- create an enhanched table from an old one
local tb = table(t)
-- print every element
tb:eachi(print)
-- or print the entire table (with key-value pairs)
print(tb)
-- double and sum values
local sum = tb:map(table.double):reduce(0, table.sum)
-- remove duplicates
tb = table.unique(tb)
-- clear and add values to table
tb:clear()
tb:append(4, 5, 6)
tb:push(1, 2, 3)
-- table equality
local t1 = { 1, 2, 3, x = { 4, 5 } }
local t2 = { 1, 2, 3, 4, 5 }
print(table.equal(t1, t2)) --> false
print(table.equal(t1, t2, true)) --> true
-- operator overloads
local t1 = table { 1, 2, 3 }
local t2 = table { 2, 4, 5 }
print(t1 + t2) -- table.union
print(t1 - t2) -- table.negation
print(t1 * t2) -- table.intersect
print(t1 == t2) -- table.equal
print(t1 .. t2) -- table.merge
