Install

Unzip the downloaded file into an arbitrary folder. This will create a single sub-folder named ulua which contains the ULua distribution:

ulua
├── lua.cmd           # LuaJIT executable for Windows.
├── lua               # LuaJIT executable for OSX and Linux.
├── host
│   ├── config.lua    # Global configuration (see PKG).
│   ├── init          # Initialization scripts folder.
│   ├── tmp           # Temporary files folder.
│   └── pkg           # Downloaded packages cache folder.
├── bin
│   ├── upkg.cmd      # Package manager executable for Windows.
│   ├── upkg          # Package manager executable for OSX and Linux.
│   └── ...           # Other executables depending on installed packages.
├── pkg               # Package manager package.
└── ...               # Other installed packages.

Run

The lua executable starts LuaJIT, the Lua manual and the LuaJIT manual document its usage:

# On Windows:
cd folder_containing_ulua/ulua
lua      [options] [script [args]]

# On OSX and Linux:
cd folder_containing_ulua/ulua
./lua    [options] [script [args]]

By default LuaJIT runs in 32-bit mode, to run it in 64-bit mode set the environment variable BIT=64:

set BIT=64       # On Windows.
export BIT=64    # On OSX and Linux.

On Linux, if LuaJIT 32-bit is executed on a distribution lacking the 32-bit C runtime, this will result in a meaningless error such as luajit: command not found. Either launch LuaJIT in 64-bit mode or install the required Linux libraries.

Packages

The upkg executable provides a convenient way of managing ULua:

# On Windows:
cd folder_containing_ulua/ulua/bin
upkg available     # List all available packages.
upkg add socket    # Download and install the socket package (LuaSocket library).
upkg add pl        # Download and install the pl package (PenLight library).
upkg update        # Update all packages to the latest version.

# On OSX and Linux:
cd folder_containing_ulua/ulua/bin
./upkg available     # List all available packages.
./upkg add socket    # Download and install the socket package (LuaSocket library).
./upkg add pl        # Download and install the pl package (PenLight library).
./upkg update        # Update all packages to the latest version.

ULua features LuaRocks integration: new and updated rocks are automatically tracked, compiled and made available in ULua. More than 300 of such packages are currently available for installation, see LuaRocks Modules.

ULua also features a number of Native packages, i.e. packages that are developed directly for ULua according to its package manager specifications.
