texlua

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  back-
       slash, 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 remain-
       ing 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  pars-
       ing 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
       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  com-
              mand  can be any shell command.  This construct is normally dis-
              allowed for security reasons.

       --no-shell-escape
              Disable the \write18{command} construct and the other Lua  func-
              tions, 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 simi-
              lar 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

       --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  direc-
              tory.   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 under-
              stood 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 mali-
              cious 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.
