The Lua language is an easy to use and high performance scripting language. The Fluxweave Platform provides a Lua API and scripting interface for easy access to Org data and for integrating with other systems.


For security reasons the majority of the standard library has been disabled. Table features are still active.

Available libraries


local ls = core.QueryDispatch("given trackers [journal]")

for index, dispatch in pairs(ls) do

Introduction to working with Lua

Simple numbers

local n = 0
n = n + 1


local str = "Hello"
str = str .. ", world!"

Arrays and objects

local arr = {"apples", "oranges"}
local obj = {foo = "hey", bar = "there"}

table.insert(arr, "kiwi")

obj.other = "hello" (obj)

Flow control

local test = 5
if test == 5 then"its 5")

Working with Lua arrays and tables

Most functions take or return lua tables. These are map data structures that can be key value pair or simple lists where the key is an increasing integer.

To iterate a range

for n=1,20 do

To create an iterate an array

local numbers = {1, 5, 24, 44, 80}
for index, n in pairs(numbers) do

To iterate a list

for index, item in pairs(list) do 
    -- do something with the item

To get and set values

local data = {foo="hello", bar="goodbye"}["bar"])
data["another"] = "hello again"
