NAME

       hitex - HINT output from TeX

SYNOPSIS

       hitex [options] [&format] [file|\commands]

DESCRIPTION

       Run  the HiTeX typesetter on file, usually creating file.hnt.  If the file argument has no
       extension, ".tex" will be appended to it.  Instead of a file name, a set of HiTeX commands
       can  be  given,  the  first of which must start with a backslash.  With a &format argument
       HiTeX uses a different set of precompiled commands, contained in format.fmt; it is usually
       better to use the -fmt format option instead.

       HiTeX  is  a  version of TeX that creates HINT files. The HINT file format is designed for
       on-screen reading of documents. Using a HINT viewer (see  https://hint.userweb.mwn.de)  to
       display a HINT file its content will dynamically adapt to the available display area.

       The  typical  use  of  HiTeX  is  with  pre generated formats.  The hitex command uses the
       equivalent of the plain TeX format, and the hilatex command uses  the  equivalent  of  the
       LaTeX format.  To generate formats, use the -ini switch.

       HiTeX's  handling  of  its  command-line  arguments is similar to that of of the other TeX
       programs in the web2c implementation.

       HiTeX incorporates the e-TeX extensions (see etex(1)) if used with the -etex switch.

       HiTeX incorporates the extensions needed for LaTeX (see latex(1)) if used  with  the  -ltx
       switch.

OPTIONS

       This version of HiTeX understands the following command line options.

       -cnf-line string
              Parse string as a texmf.cnf configuration line.  See the Kpathsea manual.

       -compress
              Enable  the  use of compression for the HINT file. Compressed files are smaller but
              require decompression when viewing. Use only for  large  files  if  the  file  size
              matters.

       -empty-page
              When  writing books, often empty pages are inserted - for example to begin chapters
              on a right hand side page. These empty pages are a nuisance for  on-screen  reading
              where  there are no left or right hand side pages. This option keeps empty pages in
              the output.

       -no-empty-page
              This option tries to eliminate empty pages in the output. It is set as a default.

       -etex  Enable the e-TeX extensions.  This option is only  effective  in  combination  with
              -ini.  See etex(1).

       -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 HiTeX
              was called or a %& line.

       -help  Print help message and exit.

       -hint-debug bitmask
              Sets  HINT file debugging flags according to the bitmask.  See the -hint-debug-help
              option for details.

       -hint-debug-help
              Print an explanation of the HINT debugging flags and exit.

       -hyphenate-first-word
              TeX will usually not attempt to insert hyphenation points into the first word of  a
              paragraph. If a HINT file must be displayed on a very small device such hyphenation
              points might prove necessary. This  option  is  set  by  default  and  enables  the
              generation of these hyphenation points.

       -no-hyphenate-first-word
              Disable  the  automatic  insertion  of  hyphenation  points  in the first word of a
              paragraph. Needed only if complete compatibility with TeX is required.

       -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.

       -ltx   Enable  the  LaTeX  extensions.   This option is only effective in combination with
              -ini.  See latex(1).

       -mfmode mode
              Use mode as the Metafont mode when generating missing fonts. See mf(1) for details.

       -mktex fmt
              Enable mktexfmt, where fmt must be either tex, tfm, fmt, or pk.

       -no-mktex fmt
              Disable mktexfmt, where fmt must be either tex, tfm, fmt, or pk.

       -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.

       -parse-first-line
              If the first line of the main input file begins with %& parse it to look for a dump
              name.

       -no-parse-first-line
              Disable parsing of the first line of the main input file.

       -progname name
              Pretend to be program name.  This affects both  the  format  used  and  the  search
              paths.

       -resolution number
              When  using  Metafont to generate missing pk fonts, use a resolution of number DPI.
              See mf(1) for details.

       -version
              Print version information and exit.

ENVIRONMENT

       See the Kpathsea library documentation (e.g., the `Path specifications' node) for  precise
       details  of  how the environment variables are used.  The kpsewhich utility can be used to
       query the values of the variables.

       One caveat: In most HiTeX formats, you cannot use ~ in a file name you  give  directly  to
       HiTeX,  because  ~ is an active character in TeX, and hence is expanded, not taken as part
       of the file name. Other programs, such as Metafont, do not have this problem.

       TEXMFOUTPUT
              Normally, HiTeX puts its output files in the current directory.  If any output file
              cannot  be  opened  there,  it  tries  to open it in the directory specified in the
              environment variable TEXMFOUTPUT.  There is no default  value  for  that  variable.
              For  example,  if you say hitex paper and the current directory is not writable and
              TEXMFOUTPUT has the value  /tmp,  HiTeX  attempts  to  create  /tmp/paper.log  (and
              /tmp/paper.hnt,  if any output is produced.)  TEXMFOUTPUT is also checked for input
              files, as TeX often generates files that need to be subsequently read;  for  input,
              no  suffixes  (such  as  ``.tex'')  are  added by default, the input name is simply
              checked as given.

       TEXINPUTS
              Search path for \input and \openin files.  This normally starts with ``.'', so that
              user files are found before system files.  An empty path component will be replaced
              with the paths defined in the  texmf.cnf  file.   For  example,  set  TEXINPUTS  to
              ".:/home/user/tex:"  to prepend the current directory and ``/home/user/tex'' to the
              standard search path.

       TEXFORMATS
              Search path for format files.

       TFMFONTS
              Search path for font metric (.tfm) files.

       SOURCE_DATE_EPOCH
              If set, its value, taken to be in epoch-seconds, will be used for the creation date
              and  as  the  reference  moment  for  the time related primitives of LaTeX. This is
              useful for making reproducible builds.

       FORCE_SOURCE_DATE
              If set to the value "1", the time-related  TeX  primitives  (\year,  \month,  \day,
              \time)  are  also  initialized  from  the  value of SOURCE_DATE_EPOCH.  This is not
              recommended if there is any viable alternative.

       Many, many more environment variables may be consulted related to path searching.  See the
       Kpathsea manual.

NOTES

       This manual page is not meant to be exhaustive.  The complete documentation for HiTeX  can
       be  found  in the HiTeX user manual Further information can be found in the  manual of the
       Kpathsea library and in HINT: The  file  format  which  is  available  as  a  book  or  in
       electronic form from the HINT project home page at https://hint.userweb.mwn.de.

BUGS

       This  version of HiTeX fails to handle correctly glues and kerns with a width that depends
       on \hsize or \vsize. Similarly, when the layout of table entries or mathematical  formulas
       depends on \hsize or \vsize their output might be distorted.

AVAILABILITY

       HiTeX  should  compile  on a large variety of machine architectures and operating systems.
       HiTeX is part of the TeX Live distribution.

       The HiTeX  home  page  is  at  https://hint.userweb.mwn.de.   There  you  find  additional
       software, most importantly viewers for HINT files, and further information.
