Installs LuaRocks.
/P [dir] Where to install LuaRocks.
Default is %PROGRAMFILES%\LuaRocks
Configuring the destinations:
/TREE [dir] Root of the local system tree of installed rocks.
Default is {BIN}\..\ if {BIN} ends with '\bin'
otherwise it is {BIN}\systree.
/SCRIPTS [dir] Where to install commandline scripts installed by
rocks. Default is {TREE}\bin.
/LUAMOD [dir] Where to install Lua modules installed by rocks.
Default is {TREE}\share\lua\{LV}.
/CMOD [dir] Where to install c modules installed by rocks.
Default is {TREE}\lib\lua\{LV}.
/CONFIG [dir] Location where the config file should be installed.
Default is to follow /P option
/SELFCONTAINED Creates a self contained installation in a single
directory given by /P.
Sets the /TREE and /CONFIG options to the same
location as /P. And does not load registry info
with option /NOREG. The only option NOT self
contained is the user rock tree, so don't use that
if you create a self contained installation.
Configuring the Lua interpreter:
/LV [version] Lua version to use; either 5.1, 5.2, 5.3, or 5.4.
Default is auto-detected.
/LUA [dir] Location where Lua is installed - e.g. c:\lua\5.1\
If not provided, the installer will search the system
path and some default locations for a valid Lua
installation.
This is the base directory, the installer will look
for subdirectories bin, lib, include. Alternatively
these can be specified explicitly using the /INC,
/LIB, and /BIN options.
/INC [dir] Location of Lua includes - e.g. c:\lua\5.1\include
If provided overrides sub directory found using /LUA.
/LIB [dir] Location of Lua libraries (.dll/.lib) - e.g. c:\lua\5.1\lib
If provided overrides sub directory found using /LUA.
/BIN [dir] Location of Lua executables - e.g. c:\lua\5.1\bin
If provided overrides sub directory found using /LUA.
/L Install LuaRocks' own copy of Lua even if detected,
this will always be a 5.1 installation.
(/LUA, /INC, /LIB, /BIN cannot be used with /L)
Compiler configuration:
By default the installer will try to determine the
Microsoft toolchain to use. And will automatically use
a setup command to initialize that toolchain when
LuaRocks is run. If it cannot find it, it will default
to the /MSVC switch.
/MSVC Use MS toolchain, without a setup command (tools must
be in your path)
/MW Use mingw as build system (tools must be in your path)
Other options:
/FORCECONFIG Use a single config location. Do not use the
LUAROCKS_CONFIG variable or the user's home directory.
Useful to avoid conflicts when LuaRocks
is embedded within an application.
/F Remove installation directory if it already exists.
/NOREG Do not load registry info to register '.rockspec'
extension with LuaRocks commands (right-click).
/NOADMIN The installer requires admin privileges. If not
available it will elevate a new process. Use this
switch to prevent elevation, but make sure the
destination paths are all accessible for the current
user.
/Q Do not prompt for confirmation of settings
