.SH NAME

luajit \- Just-In-Time Compiler for the Lua Language
|
|
\fB
|
|
.SH SYNOPSIS
|
|
.B luajit
|
|
[\fIoptions\fR]... [\fIscript\fR [\fIargs\fR]...]
|
|
.SH "WEB SITE"

|
|
.SH DESCRIPTION
|
|
.PP
|
|
This is the command-line program to run Lua programs with \fBLuaJIT\fR.
|
|
.PP
|
|
\fBLuaJIT\fR 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.
|
|
.PP
|
|
\fBLuaJIT\fR 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.
|
|
.SH OPTIONS
|
|
.TP
|
|
.BI "\-e " chunk
|
|
Run the given chunk of Lua code.
|
|
.TP
|
|
.BI "\-l " library
|
|
Load the named library, just like \fBrequire("\fR\fIlibrary\fR\fB")\fR.
|
|
.TP
|
|
.BI "\-b " ...
|
|
Save or list bytecode. Run without arguments to get help on options.
|
|
.TP
|
|
.BI "\-j " command
|
|
Perform LuaJIT control command (optional space after \fB\-j\fR).
|
|
.TP
|
|
.BI "\-O" [opt]
|
|
Control LuaJIT optimizations.
|
|
.TP
|
|
.B "\-i"
|
|
Run in interactive mode.
|
|
.TP
|
|
.B "\-v"
|
|
Show \fBLuaJIT\fR version.
|
|
.TP
|
|
.B "\-E"
|
|
Ignore environment variables.
|
|
.TP
|
|
.B "\-\-"
|
|
Stop processing options.
|
|
.TP
|
|
.B "\-"
|
|
Read script from stdin instead.
|
|
.PP
|
|
After all options are processed, the given \fIscript\fR is run.
|
|
The arguments are passed in the global \fIarg\fR table.
|
|
.PP
|
|
Interactive mode is only entered, if no \fIscript\fR and no \fB\-e\fR
|
|
option is given. Interactive mode can be left with EOF (\fICtrl\-Z\fB).
|
|
.SH EXAMPLES
|
|
.TP
|
|
luajit hello.lua world
|
|
|
|
Prints "Hello world", assuming \fIhello.lua\fR contains:
|
|
.br
|
|
print("Hello", arg[1])
|
|
.TP
|
|
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.
|
|
.br
|
|
And finishes in a reasonable amount of time, too.
|
|
.TP
|
|
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.
