PROGRAM:

NAME


luac - Lua compiler

SYNOPSIS


luac [ options ] [ filenames ]

DESCRIPTION


luac is the Lua compiler. It translates programs written in the Lua programming language
into binary files that can be later loaded and executed.

The main advantages of precompiling chunks are: faster loading, protecting source code
from accidental user changes, and off-line syntax checking.

Pre-compiling does not imply faster execution because in Lua chunks are always compiled
into bytecodes before being executed. luac simply allows those bytecodes to be saved in a
file for later execution.

Pre-compiled chunks are not necessarily smaller than the corresponding source. The main
goal in pre-compiling is faster loading.

The binary files created by luac are portable only among architectures with the same word
size and byte order.

luac produces a single output file containing the bytecodes for all source files given.
By default, the output file is named luac.out, but you can change this with the -o option.

In the command line, you can mix text files containing Lua source and binary files
containing precompiled chunks. This is useful to combine several precompiled chunks, even
from different (but compatible) platforms, into a single precompiled chunk.

You can use '-' to indicate the standard input as a source file and '--' to signal the end
of options (that is, all remaining arguments will be treated as files even if they start
with '-').

The internal format of the binary files produced by luac is likely to change when a new
version of Lua is released. So, save the source files of all Lua programs that you
precompile.

OPTIONS


Options must be separate.

-l produce a listing of the compiled bytecode for Lua's virtual machine. Listing
bytecodes is useful to learn about Lua's virtual machine. If no files are given,
then luac loads luac.out and lists its contents.

-o file
output to file, instead of the default luac.out. (You can use '-' for standard
output, but not on platforms that open standard output in text mode.) The output
file may be a source file because all files are loaded before the output file is
written. Be careful not to overwrite precious files.

-p load files but do not generate any output file. Used mainly for syntax checking
and for testing precompiled chunks: corrupted files will probably generate errors
when loaded. Lua always performs a thorough integrity test on precompiled chunks.
Bytecode that passes this test is completely safe, in the sense that it will not
break the interpreter. However, there is no guarantee that such code does anything
sensible. (None can be given, because the halting problem is unsolvable.) If no
files are given, then luac loads luac.out and tests its contents. No messages are
displayed if the file passes the integrity test.

-s strip debug information before writing the output file. This saves some space in
very large chunks, but if errors occur when running a stripped chunk, then the
error messages may not contain the full information they usually do. For instance,
line numbers and names of local variables are lost.

-v show version information.
