NAME

6       aleph - extended Unicode TeX
7

SYNOPSIS

9       aleph [options] [&format] [file|\commands]
10

DESCRIPTION

12       Run  the  Aleph  typesetter on file, usually creating file.dvi.  If the
13       file argument has no extension, ".tex" will be appended to it.  Instead
14       of a filename, a set of Aleph commands can be given, the first of which
15       must start with a backslash.  With a &format argument Aleph uses a dif‐
16       ferent set of precompiled commands, contained in format.fmt; it is usu‐
17       ally better to use the -fmt format option instead.
18
19       Aleph is a version of the TeX program modified for  multilingual  type‐
20       setting.   It  uses  Unicode,  and has additional primitives for (among
21       other things) bidirectional typesetting.
22
23       Aleph's command line options are similar to those of TeX.
24
25       Aleph is no longer being actively developed;  see  LuaTeX  for  current
26       activity.

OPTIONS

29       Run  aleph  --help  to  see  the  complete list of options; this is not
30       exhaustive.
31
32       --fmt format
33              Use format as the name of the format to be used, instead of  the
34              name by which Aleph was called or a %& line.
35
36       --halt-on-error
37              Exit with an error code when an error is encountered during pro‐
38              cessing.
39
40       --help Print help message and exit.
41
42       --ini  Be `initial' Aleph for dumping formats; this is implicitly  true
43              if the program is called as inialeph.
44
45       --interaction mode
46              Sets  the  interaction  mode.  The mode can be one of batchmode,
47              nonstopmode, scrollmode,  and  errorstopmode.   The  meaning  of
48              these modes is the same as that of the corresponding \commands.
49
50       --ipc  Send  DVI  output  to a socket as well as the usual output file.
51              Whether this option is available is the choice of the installer.
52
53       --ipc-start
54              As --ipc, and starts the  server  at  the  other  end  as  well.
55              Whether this option is available is the choice of the installer.
56
57       --kpathsea-debug bitmask
58              Sets  path  searching  debugging flags according to the bitmask.
59              See the Kpathsea manual for details.
60
61       --maketex fmt
62              Enable mktexfmt, where fmt must be one of tex or tfm.
63
64       --no-maketex fmt
65              Disable mktexfmt, where fmt must be one of tex or tfm.
66
67       --output-comment string
68              Use string for the DVI file comment instead of the date.
69
70       --output-directory directory
71              Write output files in directory instead of  the  current  direc‐
72              tory.   Look  up  input  files in directory first, the along the
73              normal search path.
74
75       --parse-first-line
76              If the first line of the main input file begins with %& parse it
77              to look for a dump name.
78
79       --progname name
80              Pretend  to  be program name.  This affects both the format used
81              and the search paths.
82
83       --recorder
84              Enable the filename recorder.  This leaves a trace of the  files
85              opened  for  input  and  output  in  a file with extension .ofl.
86              (This option is always on.)
87
88       --shell-escape
89              Enable the \write18{command} construct.  The command can be  any
90              Bourne  shell command.  By default, this construct is enabled in
91              a restricted mode, for security reasons.
92
93       --version
94              Print version information and exit.
95

ENVIRONMENT

97       See the Kpathsearch library documentation  (the  `Path  specifications'
98       node)  for  precise  details of how the environment variables are used.
99       The kpsewhich utility can be used to query the values of the variables.
100
101       One caveat: In most Aleph formats, you cannot use ~ in a  filename  you
102       give  directly to Aleph, because ~ is an active character, and hence is
103       expanded, not taken as part of the filename.  Other programs,  such  as
104       Metafont, do not have this problem.
105
106       TEXMFOUTPUT
107              Normally,  Aleph puts its output files in the current directory.
108              If any output file cannot be opened there, it tries to  open  it
109              in the directory specified in the environment variable TEXMFOUT‐
110              PUT.  There is no default value for that variable.  For example,
111              if  you say tex paper and the current directory is not writable,
112              if TEXMFOUTPUT has the value  /tmp,  Aleph  attempts  to  create
113              /tmp/paper.log  (and /tmp/paper.dvi, if any output is produced.)
114              TEXMFOUTPUT is also checked for input files, as TeX often gener‐
115              ates files that need to be subsequently read; for input, no suf‐
116              fixes (such as ``.tex'') are added by default, the input name is
117              simply checked as given.
118
119       TEXINPUTS
120              Search  path  for  \input  and \openin files.  This should start
121              with ``.'', so that user files are found  before  system  files.
122              An  empty path component will be replaced with the paths defined
123              in  the  texmf.cnf  file.   For  example,   set   TEXINPUTS   to
124              ".:/home/user/tex:"   to   prepend   the  current  direcory  and
125              ``/home/user/tex'' to the standard search path.
126
127       TEXEDIT
128              Command template for switching to editor.  The default,  usually
129              vi, is set when Aleph is compiled.

NOTES

132       This  manual page is not meant to be exhaustive.  The complete documen‐
133       tation for this version of Aleph can be found in the info manual Web2C:
134       A TeX implementation.  See http://tug/org/web2c.

BUGS

137       This  version  of Aleph implements a number of optional extensions.  In
138       fact, many of these extensions conflict to a greater or  lesser  extent
139       with  the  definition  of Aleph.  When such extensions are enabled, the
140       banner printed when Aleph starts is changed to print Alephk instead  of
141       Aleph.
142
143       This version of Aleph fails to trap arithmetic overflow when dimensions
144       are added or subtracted.  Cases where this occurs are rare, but when it
145       does the generated DVI file will be invalid.
