# aleph

```       aleph [options] [&format] [file|\commands]

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

Aleph is a version of the TeX program modified for  multilingual  type-
setting.   It  uses  Unicode,  and has additional primitives for (among
other things) bidirectional typesetting.

Aleph's command line options are similar to those of TeX.

Aleph is no longer being actively developed;  see  LuaTeX  for  current
activity.

OPTIONS
Run  aleph  --help  to  see  the  complete list of options; this is not
exhaustive.

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

--halt-on-error
Exit with an error code when an error is encountered during pro-
cessing.

--help Print help message and exit.

--ini  Be `initial' Aleph for dumping formats; this is implicitly  true
if the program is called as inialeph.

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

--ipc  Send  DVI  output  to a socket as well as the usual output file.
Whether this option is available is the choice of the installer.

--ipc-start
As --ipc, and starts the  server  at  the  other  end  as  well.
Whether this option is available is the choice of the installer.

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

--maketex fmt
Enable mktexfmt, where fmt must be one of tex or tfm.

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

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

--recorder
Enable the filename recorder.  This leaves a trace of the  files
opened  for  input  and  output  in  a file with extension .ofl.
(This option is always on.)

--shell-escape
Enable the \write18{command} construct.  The command can be  any
Bourne  shell command.  By default, this construct is enabled in
a restricted mode, for security reasons.

--version
Print version information and exit.

ENVIRONMENT
See the Kpathsearch library documentation  (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 Aleph formats, you cannot use ~ in a  filename  you
give  directly to Aleph, because ~ is an active character, and hence is
expanded, not taken as part of the filename.  Other programs,  such  as
Metafont, do not have this problem.

TEXMFOUTPUT
Normally,  Aleph 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 TEXMFOUT-
PUT.  There is no default value for that variable.  For example,
if  you say tex paper and the current directory is not writable,
if TEXMFOUTPUT has the value  /tmp,  Aleph  attempts  to  create
/tmp/paper.log  (and /tmp/paper.dvi, if any output is produced.)
TEXMFOUTPUT is also checked for input files, as TeX often gener-
ates files that need to be subsequently read; for input, no suf-
fixes (such as ``.tex'') are added by default, the input name is
simply checked as given.

TEXINPUTS
Search  path  for  \input  and \openin files.  This should start
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  direcory  and
``/home/user/tex'' to the standard search path.

TEXEDIT
Command template for switching to editor.  The default,  usually

Aleph.

This version of Aleph fails to trap arithmetic overflow when dimensions
are added or subtracted.  Cases where this occurs are rare, but when it
does the generated DVI file will be invalid.
