NAME
luatex, texlua, texluac - An extended version of pdfTeX using Lua as an embedded scripting language

SYNOPSIS
luatex [--lua=FILE] [OPTION]...	[TEXNAME[.tex]] [COMMANDS]
luatex [--lua=FILE] [OPTION]...	\FIRST-LINE
luatex [--lua=FILE] [OPTION]...	&FMT [ARGS]

DESCRIPTION
Run the luaTeX typesetter on TEXNAME, usually creating TEXNAME.pdf.  Any remaining COMMANDS are processed as luaTeX input, after TEXNAME is

Alternatively, if the first non-option argument begins with a backslash, interpret all non-option arguments as a line of luaTeX input.

Alternatively, if the first non-option argument begins with a &, the next word is taken as the  FMT  to	read,  overriding  all	else.  Any
remaining arguments are processed as above.

If no arguments or options are specified, prompt for input.

If called as texlua it acts as lua interpreter.	If called as texluac it acts as lua bytecode compiler.

LuaTeX  is an extended version of pdfTeX with Unicode and OpenType font support, embeded Lua scripting language, the e-TeX and Omega exten-
sions, as well as integrated MetaPost engine, that can create PDF files as well as DVI files.   For  more  information  about  luatex,  see
http://www.luatex.org, you can read LuaTeX manual using texdoc utility (texdoc luatex).

All LuaTeX text input and output is considered to be Unicode text.

In DVI mode, luaTeX can be used as a complete replacement for the TeX engine.

In  PDF	mode,  luaTeX can natively handle the PDF, JPG, JBIG2, and PNG graphics formats.  luaTeX cannot include PostScript or Encapsulated
PostScript (EPS) graphics files; first convert them to PDF using epstopdf (1).

OPTIONS
When the LuaTeX executable starts, it looks for the --lua commandline option.  If there is no --lua option, the commandline is  interpreted
in a similar fashion as in traditional pdfTeX and Aleph. But if the option is present, LuaTeX will enter an alternative mode of commandline
parsing in comparison to the standard web2c programs. The presence of --lua makes most of other options unreliable, because  the  lua  ini-
tialization file can disable kpathsea and/or hook functions into various callbacks.

--lua=FILE
The lua initialization file.

The following two options alter the executable behaviour:

--luaonly
Start  LuaTeX  as  a  Lua interpreter. In this mode, it will set Lua's arg[0] to the found script name, pushing preceding options in
negative values and the rest of the commandline in the positive values, just like the Lua interpreter. LuaTeX will exit  immediately
after executing the specified Lua script.

--luaconly
Start  LuaTeX as a Lua byte compiler. In this mode, LuaTeX is exactly like luac from the standalone Lua distribution, except that it
does not have the -l switch, and that it accepts (but ignores) the --luaconly switch.

Then the regular web2c options:

--debug-format

--draftmode
Sets \pdfdraftmode so luaTeX doesn't write a PDF and doesn't read any included images, thus speeding up execution.

--enable-write18
Synonym for --shell-escape.

--disable-write18
Synonym for --no-shell-escape.

--shell-escape
Enable the \write18{command} construct, and Lua functions os.execute(), os.exec(), os.spawn(), and io.popen().  The command  can	be
any shell command.  This construct is normally disallowed for security reasons.

--no-shell-escape
Disable the \write18{command} construct and the other Lua functions, even if it is enabled in the texmf.cnf file.

--shell-restricted
Enable  restricted  version of \write18, os.execute(), os.exec(), os.spawn(), and io.popen(), only commands listed in texmf.cnf file
are allowed.

--file-line-error
Print error messages in the form file:line:error which is similar to the way many compilers format them.

--no-file-line-error
Disable printing error messages in the file:line:error style.

--fmt=FORMAT
Use FORMAT as the name of the format to be used, instead of the name by which luaTeX was called or a %& line.

--help Print help message and exit.

--ini  Start in INI mode, which is used to dump formats.  The INI mode can be used for typesetting, but no format is preloaded,	and  basic
initializations like setting catcodes may be required.

--interaction=MODE
Sets  the  interaction  mode.   The  MODE can be either batchmode, nonstopmode, scrollmode, and errorstopmode.  The meaning of these
modes is the same as that of the corresponding \commands.

--jobname=NAME
Use NAME for the job name, instead of deriving it from the name of the input file.

Sets path searching debugging flags according to the BITMASK.  See the Kpathsea manual for details.

--mktex=FMT
Enable mktexFMT generation, where FMT must be either tex or tfm.

--nosocket
Disable the luasocket (network) library.

--output-comment=STRING
In DVI mode, use STRING for the DVI file comment instead of the date.  This option is ignored inPDF mode.

--output-directory=DIRECTORY
Write output files in DIRECTORY instead of the current directory.  Look up input files in DIRECTORY first,  then	along  the  normal
search path.

--output-format=FORMAT
Set  the output format mode, where FORMAT must be either pdf or dvi.  This also influences the set of graphics formats understood by
luaTeX.

--progname=NAME
Pretend to be program NAME (only for kpathsea).

--recorder
Enable the filename recorder.  This leaves a trace of the files opened for input and output in a file with extension .fls.

--safer
Disable some Lua commands that can easily be abused by a malicious document.

--synctex=NUMBER
Enable/disable SyncTeX extension.

--version
Print version information and exit.

--credits
Print credits and version details.

The following options are ignored:

--8bit, --etex, --parse-first-line, --no-parse-first-line
These are always on.

--default-translate-file=TCXNAME, --translate-file=TCXNAME
These are always off.
