User Commands 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) output.
This includes links, but the more advanced graphics
packages of Lout are not supported.
-PDF Synonym for -Z.
Cross-reference database
-s Suppress all reading and writing of the cross reference
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 compilation
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 certainly 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 installation
(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 mul-
tiple -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). @SysInclude 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 mul-
tiple -C options; the directories are searched in the
order given, and finally the default character 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 mul-
tiple -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). @SysData-
base omits the search of the current directory.
Miscellaneous options
-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 refer-
ence 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.
