       luac - Lua compiler

       luac [ options ] [ filenames ]

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

       The  main  advantages  of precompiling chunks are: faster loading, pro‐
       tecting source code from accidental user changes, and  off-line	syntax
       checking.   Precompiling 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 execu‐
       tion.  Precompiled chunks are not necessarily smaller than  the	corre‐
       sponding source.	 The main goal in precompiling is faster loading.

       In  the	command line, you can mix text files containing Lua source and
       binary files containing precompiled chunks.   luac  produces  a	single
       output  file  containing	 the  combined	bytecodes for all files given.
       Executing the combined file is equivalent to executing the given files.
       By  default, the output file is named luac.out, but you can change this
       with the -o option.

       Precompiled chunks are not  portable  across  different	architectures.
       Moreover, the internal format of precompiled chunks is likely to change
       when a new version of Lua is released.  Make sure you save  the	source
       files of all Lua programs that you precompile.

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

       -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 one of  the	 given
	      files  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.	 If  no	 files
	      are  given, then luac loads luac.out and tests its contents.  No
	      messages are displayed if the file loads without errors.

       -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  con‐
	      tain  the full information they usually do.  In particular, line
	      numbers and names of local variables are lost.

       -v     show version information.

       --     stop handling options.

       -      stop handling options and process standard input.

       The documentation at

       Error messages should be self explanatory.
