NAME
luajit - Just-In-Time Compiler for the Lua LanguageSYNOPSIS
luajit [options]... [script [args]...]WEB SITE
http://luajit.orgDESCRIPTION
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.
OPTIONS
- -e chunk
- Run the given chunk of Lua code.
- -l library
- Load the named library, just like require("library").
- -j command
- Perform LuaJIT control command (optional space after -j).
- -O[opt]
- Control LuaJIT optimizations.
- -i
- Run in interactive mode.
- -v
- Show LuaJIT version.
- --
- 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).
EXAMPLES
- 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.
