LOUT(1) LOUT(1)
NAME
lout - prepare Lout document for printing
SYNOPSIS
lout [ options ] file...
DESCRIPTION
Invoke the Basser Lout interpreter on the concatenation of
the named files, producing a PostScript file on standard
output suitable for printing on PostScript printers using
lpr(1). If no files are named, stdin is used instead.
The special file name `-' may be used to denote standard
input. White space between flags and their associated
option values is optional.
An optional .lt suffix may be used for Lout source and
include files. When invoking files ending in this suffix
the suffix may be omitted.
OPTIONS
Output
-o filename
Direct output to filename instead of to stdout.
-e filename
Direct error messages to filename instead of to
stderr.
-a Use "filename:linenum:colnum:message" alternative
error message format (useful with Emacs compilation
mode and other tools).
Output format
-EPS Produce output in the form of an EPS (Encapsulated
PostScript) file, suitable for inclusion in another
document. Useful with stand-alone illustrations.
-p Produce plain text output instead of PostScript.
-P Like -p, but with a form-feed character between
pages.
-Z Produce Adobe Portable Document Format (PDF) out
put. This includes links, but the more advanced
graphics packages of Lout are not supported.
-PDF Synonym for -Z.
-t Ignore texture-changing options; everything that
would otherwise have been printed using a texture
will be printed in solid colour.
Cross-reference database
-s Suppress all reading and writing of the cross ref
erence database; other databases are not affected.
Useful when many simple documents that don't do any
cross referencing are stored in one directory.
-l Use ASCII order when sorting index entries etc.;
the default depends on the COLLATE compilation
option (use -V option to find out your default
value).
-L Use your locale's order when sorting index entries
etc.; the default depends on the COLLATE compila
tion option (use -V option to find out your default
value).
Execution of filters
-S Safe execution: disable all calls to system(3),
instead echoing the commands that would have been
executed. Although this makes the Lout run cer
tainly safe, the PostScript output file may not be.
-U Unsafe execution: allow calls to system(3). This
is usually the default behavior, but it is possible
to make safe execution the default during installa
tion (use -V option to find out whether this was
done or not), hence the need for this flag.
Changing document setup options
--option{value}
Set setup file option to value, overriding any
value assigned to option in the setup file. For
example, --@PageType{Letter} will set the @PageType
setup file option to Letter. The value may be a
sequence of words but not an arbitrary Lout object.
If there are spaces you must ensure that it is
passed to Lout as a single option; the usual way to
do this is to enclose it in quotes.
Searching for files
-i filename
Search the directories of the include file path
(see below) for filename or filename.lt and include
it. There may be multiple -i options.
-I dirname
Add dirname to the list of directories searched for
@Include files and -i option files. There may be
multiple -I options. @Include first searches the
current directory, then searches the -I directories
in the order given, and finally searches the
default include file directory (see below). @Sys
Include and the -i option omit the search of the
current directory.
-C dirname
Add dirname to the list of directories searched for
Lout character mapping (.LCM) files. There may be
multiple -C options; the directories are searched
in the order given, and finally the default charac
ter mappings directory is searched (see below).
-F dirname
Add dirname to the list of directories searched for
font metrics (formerly .AFM) files. There may be
multiple -F options; the directories are searched
in the order given, and finally the default font
metrics directory is searched (see below).
-H dirname
Add dirname to the list of directories searched for
hyphenation patterns files, both unpacked (.lh) and
packed (.lp). There may be multiple -H options;
the directories are searched in the order given,
and finally the default hyphenation directory is
searched (see below).
-D dirname
Add dirname to the list of directories searched for
Lout database files. There may be multiple -D
options. @Database searches the current directory,
then the -D directories in the order given, and
finally searches the default databases directory
(see below). @SysDatabase omits the search of the
current directory.
Miscellaneous options
-r num Run Lout num times, producing output only on the
last run. Useful for bringing cross references up
to date quickly.
-x Initializing run, not for ordinary use: read and
check all font files mentioned in font definitions,
read and check all hyphenation files mentioned in
language definitions and build compressed versions,
read and check all database files mentioned in
database clauses and build index files.
-u Print usage information on stderr and exit.
-V Print version information on stderr and exit.
-M Use less memory and run more slowly (the cross ref
erence database index will be kept in a file rather
than in memory).
-w Show the total number of non-empty words printed in
the output file. This includes words and numbers
in page headers and footers; section numbers and
other numbers; every punctuation character in a
font different from its adjacent word; and every
little fragment of every equation; so it will
always somewhat overestimate the true number.
FILES AND ENVIRONMENT VARIABLE
Default include file directory: LOUTLIB/include
Default databases directory: LOUTLIB/data
Default font metrics directory: LOUTLIB/font
Default hyphenation directory: LOUTLIB/hyph
Default character mappings dir.: LOUTLIB/maps
Default locales directory: LOUTLIB/locale
The default library directory, usually
/usr/local/lib/lout, can be changed by setting environment
variable LOUTLIB to an alternative directory name.
