luajit - Just-In-Time Compiler for the Lua Language

LuaJIT is Copyright © 2005-2022 Mike Pall.
       LuaJIT is open source software, released under the MIT license.

       This is the command-line program to run Lua programs with LuaJIT.

       LuaJIT  is  a  just-in-time  (JIT) compiler for the Lua language.  The virtual machine (VM) is based on a
       fast interpreter combined with a trace compiler. It can significantly  improve  the  performance  of  Lua
       programs.

       LuaJIT  is API- and ABI-compatible with the VM of the standard Lua 5.1 interpreter. When embedding the VM
       into an application, the built library can be used as a drop-in replacement.

       luajit hello.lua world

              Prints "Hello world", assuming hello.lua contains:
                print("Hello", arg[1])

       luajit -e "local x=0; for i=1,1e9 do x=x+i end; print(x)"

              Calculates the sum of the numbers from 1 to 1000000000.
              And finishes in a reasonable amount of time, too.

       luajit -jv -e "for i=1,10 do for j=1,10 do for k=1,100 do end end end"

              Runs some nested loops and shows the resulting traces.

-echunk
              Run the given chunk of Lua code.

       -llibrary
              Load the named library, just like require("library").

       -b... Save or list bytecode. Run without arguments to get help on options.

       -jcommand
              Perform LuaJIT control command (optional space after -j).

       -O[opt]
              Control LuaJIT optimizations.

       -i     Run in interactive mode.

       -v     Show LuaJIT version.

       -E     Ignore environment variables.

       --     Stop processing options.

       -      Read script from stdin instead.

       After all options are processed, the given script is run.  The arguments are passed  in  the  global  arg
       table.

       Interactive  mode  is  only entered, if no script and no -e option is given. Interactive mode can be left
       with EOF (Ctrl-Z).
