Lemur reimplements a large portion of Roblox's API in Lua in order to enable Roblox projects to have continuous integration using services like Travis CI or Jenkins.

Lemur aims to be a fairly complete and up-to-date implementation of Roblox's API, however:

• Lemur will always be incomplete by nature
• Lemur will not implement deprecated APIs for the sake of simplicity
• Lemur is naturally restricted by the environment it runs in

Current feature coverage is detailed in FEATURES.md

Lemur requires:

• Lua 5.1 or LuaJIT
  • ./?/init.lua should be in your LUA_PATH. This is the default in some, but not all, installations.
• LuaFileSystem (luarocks install luafilesystem)

Lemur needs certain extra dependencies for some optional features:

• dkjson (Roblox JSON API) (luarocks install dkjson)
• LuaSocket (high performance timer) (luarocks install luasocket)
• bit32 (Lua 5.1 bit32 implementation) (luarocks install bit32)

Clone the Git repository wherever, then call require on it.

To use Lemur, create a Habitat and load pieces of the filesystem into the tree:

local lemur = require("lemur")

-- Create a Habitat
local habitat = lemur.Habitat.new()
local ReplicatedStorage = habitat.game:GetService("ReplicatedStorage")

-- Load `src/roblox` as a Folder containing some ModuleScripts:
local root = habitat:loadFromFs("src/roblox")
root.Parent = ReplicatedStorage

-- Locate src/roblox/CoolModule.lua from inside the habitat and load it!
local CoolModule = habitat:require(root.CoolModule)

-- Invoke a method on our Roblox module!
CoolModule.doSomething()

If there are any APIs you'd like that are missing, feel free to open an issue on GitHub!
