NAME

       luatex, dviluatex, luajittex, 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 read.

       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,  embedded
       Lua  scripting  language,  the  e-TeX and Omega extensions, 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 command-line option.   If  there
       is no --lua option, the command line 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
       command-line  parsing  in comparison to the standard web2c programs. The presence of --lua
       makes most of other options unreliable, because the lua initialization  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
              command  line  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
              Debug format loading.

       --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.

       --kpathsea-debug=BITMASK
              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.

AUTHORS

       The primary authors of LuaTeX are Taco Hoekwater, Hartmut Henkel, Hans  Hagen,  and  Luigi
       Scarso, with help from Martin Schröder, Karel Skoupy, and Han The Thanh.

       TeX  was  designed  by Donald E. Knuth, who implemented it using his Web system for Pascal
       programs.  It was ported to Unix at Stanford by Howard Trickey, and at  Cornell  by  Pavel
       Curtis.   The  version now offered with the Unix TeX distribution is that generated by the
       Web to C system (web2c), originally written by Tomas Rokicki and Tim Morgan.
