.SH DESCRIPTION
\f3Enscript\f1 converts text files to PostScript and spools generated
PostScript output to the specified printer or leaves it to file. If
no input files are given, \f3enscript\f1 processes standard input.
\f3Enscript\f1 can be extended to handle different output media and it
has many options which can be used to customize printouts.
.SH OPTIONS
.TP 8
.B \-# \f2num\f3
Print \f2num\f1 copies of each page.
.TP 8
.B \-1, \-2, \-\-columns=\f2num\f3
Specify how many columns each page have. With long option
\f3\-\-columns=\f2num\f1 you can specify more than 2 columns per page.
.TP 8
.B \-a \f2pages\f3, \-\-pages=\f2pages\f3
Specify which pages are printed. Page specification \f2pages\f1 can
be given in following formats:
.RS 8
.TP 8
\f2begin\f1\-\f2end\f1
print pages from \f2begin\f1 to \f2end\f1
.TP 8
\-\f2end\f1
print pages from 0 to \f2end\f1
.TP 8
\f2begin\f1\-
print pages from \f2begin\f1 to end
.TP 8
\f2page\f1
print page \f2page\f1
.TP 8
odd
print odd pages
.TP 8
even
print even pages
.RE
.TP 8
.B \-A \f2align\f3, \-\-file\-align=\f2align\f3
Align separate input files to even \f2align\f1 page count. This is
handy for two-side and 2-up printings (\-\-file\-align=2).
.TP 8
.B \-b \f2header\f3, \-\-header=\f2header\f3
Use text \f2header\f1 as a page header. The default page header is
constructed from file's name and last modification time.
The header string \f2header\f1 can contain the same formatting escapes
which can be specified for the \f3%Format\f1 directives in the user
defined fancy headers. For example, the following option prints the
file name, current data and page numbers:
\f3enscript --header='$n %W Page $% of $=' *.c\f1
The header string can also contain left, center and right justified
fields which are separated with the \f3'|'\f1 character:
\f3enscript --header='$n|%W|Page $% of $=' *.c\f1
now the file name is printed left justified, the date is centered to
the header and the page numbers are printed right justified.
.TP 8
.B \-B, \-\-no\-header
Do not print page headers.
.TP 8
.B \-c, \-\-truncate\-lines
Cut lines that are too long. As a default, \f3enscript\f1 wraps long
lines so no information is lost.
See also option \f3\-\-slice\f1 which can be used to slice long lines
to separate pages.
.TP 8
.B \-C\f1[\f2start_line\f1]\f3, \-\-line\-numbers\f1[\f3=\f2start_line\f1]\f3
Precede each line with its line number. Optional argument
\f2start_line\f1 specifies the number of the first line in the input.
The number of the first line defaults to 1.
.TP 8
.B \-d \f2name\f3
Spool output to the printer \f2name\f1.
.TP 8
.B \-D \f2key\f1[\f3:\f2value\f1]\f3, \-\-setpagedevice=\f2key\f1[\f3:\f2value\f1]\f3
Pass a page device definition to the generated PostScript output. If
no value is given, key \f2key\f1 is removed from definitions.
For example, command
.B enscript \-DDuplex:true foo.txt
prints file foo.txt in duplex (two side) mode.
Page device operators are implementation dependant but they are
standardized. See section \f3PAGE DEVICE OPTIONS\f1 for details.
.TP 8
.B \-e\f1[\f2char\f1]\f3, \-\-escapes\f1[\f3=\f2char\f1]\f3
Enable special escapes interpretation (see section \f3SPECIAL
ESCAPES\f1). If argument \f2char\f1 is given, it changes the escape
character to \f2char\f1. The default escape character is 0.
.TP 8
.B \-E\f1[\f2lang\f1]\f3, \-\-pretty\-print\f1[\f3=\f2lang\f1]\f3
Pretty-print source code by creating a special input filter with the
\f3states\f1 program. Optional argument \f2lang\f1 specifies the
language to highlight, as a default \f3states\f1 makes an educated
guess.
A description of supported highlighting languages and file formats can
be printed with command:
.B enscript \-\-help\-pretty\-print
The highlighting rules are defined in the
`@prefix@/share/enscript/enscript.st' file which can be edited to
create highlighting definitions for new languages.
\f3Note!\f1 You can't use your own input filters with this
option.
.TP 8
.B \-f \f2name\f3, \-\-font=\f2name\f3
Select font that is used for body text. The default body font is
\f2Courier10\f1, unless multicolumn landscape printing mode is
selected, in which case the default is \f2Courier7\f1.
Font specification \f2name\f1 contains two parts: font's name and
font's size in points. For example "\f3Times\-Roman12\f1" selects
"Times\-Roman" font with size 12pt.
The font specification \f2name\f1 can also be given in format
`\f2name\f1@\f2ptsize\f1', where font's name and point size are
separated by a `@' character. This allows \f3enscript\f1 to use
fonts which contain digit characters in their names.
The font point size can also be given in format
\f2width\f1/\f2height\f1 where \f2width\f1 and \f2height\f1 specify
the font's size in x- and y-directions. For example
"\f3Times\-Roman@10/12\f1" selects 10 points wide and 12 points high
"Times\-Roman" font.
\f3Note!\f1 font sizes can be given as a decimal number. For example
"\f3Times\-Roman10.2\f1" selects 10.2pt "Times\-Roman" font.
.TP 8
.B \-F \f2name\f3, \-\-header\-font=\f2name\f3
Select font for header texts.
.TP 8
.B \-g, \-\-print\-anyway
Print file even if it contains binary data. Option is here only for
compatibility since \f3enscript\f1 prints binary files anyway.
.TP 8
.B \-G, \-\-fancy\-header\f1[\f3=\f2name\f1]\f3
Print fancy page header \f2name\f1 to top of each page. Option
\f3\-G\f1 specifies the default fancy header (see section
\f3CONFIGURATION FILES\f1 to see how the default fancy header can be
changed).
.TP 8
.B \-h, \-\-no\-job\-header
Suppress printing of the job header page.
.TP 8
.B \-H\f1[\f2num\f1]\f3, \-\-highlight\-bars\f1[\f3=\f2num\f1]\f3
Specify how high highlight bars are in lines. If \f2num\f1 is not
given, the default value 2 is used. As a default, no highlight bars
are printed.
.TP 8
.B \-i \f2num\f3, \-\-indent=\f2num\f3
Indent every line \f2num\f1 characters. The indentation can also be
specified in other units by appending an unit specifier after the
number. Possible unit specifiers and the corresponding units are:
.RS 8
.TP 8
.B c
centimeters
.TP 8
.B i
inches
.TP 8
.B l
characters (default)
.TP 8
.B p
PostScript points
.RE
.TP 8
.B \-I \f2filter\f3, \-\-filter=\f2filter\f1
Read all input files through input filter \f2filter\f1. Input filter
can be a single command or a command pipeline and it can refer to the
name of the input file with escape `%s'. The name of the input file
\f3stdin\f1 can be changed with option `\f3\-\-filter\-stdin\f1'.
For example, the following command can be used to print file `foo.c'
by using only upper-case characters:
enscript --filter="cat %s | tr 'a-z' 'A-Z'" foo.c
And to highlight changes made to files since the last checkout:
enscript --filter="rcsdiff %s | diffpp %s" -e *.c
\f3Note!\f1 To include string "%s" to the filter command, you must
write it as "%%s".
.TP 8

.SH CUSTOMIZATION
Users can create their own fancy headers by creating a header
description file and placing it in a directory which is in
\f3enscript\f1's library path. The name of the header file must be in
format: `\f2headername\f1.hdr'. Header can be selected by giving
option: \f3\-\-fancy\-header=\f2headername\f1.
Header description file contains PostScript code that paints the
header. Description file must provide procedure \f3do_header\f1 which
is called by \f3enscript\f1 at the beginning of every page.
Header description file contains two parts: comments and code. Parts
are separated by a line containing text:
% \-\- code follows this line \-\-
.B Enscript
copies only the code part of description file to the generated
PostScript output. The comments part can contain any data, it is not
copied. If separator line is missing, no data is copied to output.
.B Enscript
defines following constants which can be used in header description
files:

where \f2width\f1 specifies the width of the column to which the
escape is printed. For example, escape "$5%" will expand to something
like " 12". If the width is negative, the value will be printed
left-justified.
For example, the `emacs.hdr' defines its date string with the
following format comment:

According to Adobe's Document Structuring Conventions (DSC), all
resources needed by a document must be listed in document's prolog.
Since user's can create their own headers, \f3enscript\f1 don't know
what resources those headers use. That's why all headers must contain
a standard DSC comment that lists all needed resources. For example,
used fonts can be listed with following comment:
%%DocumentNeededResources: font \f2fontname1\f1 \f2fontname2\f1
Comment can be continued to the next line with the standard
continuation comment:
%%+ font \f2fontname3\f1
.SH SPECIAL ESCAPES
\f3Enscript\f1 supports special escape sequences which can be used to
add some page formatting commands to ASCII documents. As a default,
special escapes interpretation is off, so all ASCII files print out as
everyone expects. Special escapes interpretation is activated by
giving option \f3\-e\f1, \f3\-\-escapes\f1 to \f3enscript\f1.
All special escapes start with the escape character. The default
escape character is ^@ (octal 000); escape character can be changed
with option \f3\-e\f1, \f3\-\-escapes\f1. Escape character is
followed by escape's name and optional options and arguments.
Currently \f3enscript\f1 supports following escapes:
.TP 8
.B bggray
change the text background color. Escape's syntax is:
^@bggray{\f2gray\f1}
where \f2gray\f1 is the new text background gray value. The default
value is 1.0 (white).
.TP 8
.B color
change the text color. Escape's syntax is:
^@color{\f2red\f1 \f2green\f1 \f2blue\f1}
where color components \f2red\f1, \f2green\f1 and \f2blue\f1 are given
as a decimal numbers between 0 and 1.
.TP 8
.B comment
comment the rest of the line including the newline character.
Escape's syntax is:
^@comment \f2text\f1 \f2newline_character\f1
.TP 8
.B escape
change the escape character. Escape's syntax is
^@escape{\f2code\f1}
where \f2code\f1 is the decimal code of the new escape character.
.TP 8
.B epsf
inline EPS file to the document. Escape's syntax is:
^@epsf[\f2options\f1]{\f2filename\f1}
where \f2options\f1 is an optional sequence of option characters and
values enclosed with brackets and \f2filename\f1 is the name of the
EPS file.
If \f2filename\f1 ends to the `|' character, then \f2filename\f1 is
assumed to name a command that prints EPS data to its standard output.
In this case, \f3enscript\f1 opens a pipe to the specified command
and reads EPS data from pipe.
Following options can be given for the \f3epsf\f1 escape:
.RS 8
.TP 8
.B c
print image centered
.TP 8
.B r
print image right justified
.TP 8
.B n
do not update current point. Following output is printed to that
position where the current point was just before the \f3epsf\f1 escape
.TP 8
.B nx
do not update current point \f2x\f1 coordinate
.TP 8
.B ny
do not update current point \f2y\f1 coordinate
.TP 8
.B x\f2num\f3

.TP 8
.B sy\f2num\f3
scale image in \f2y\f1 direction with factor \f2num\f1
.P
As a default, all dimensions are given in lines (vertical) and
characters (horizontal). You can also specify other units by
appending an unit specifier after number. Possible unit specifiers
and the corresponding units are:
.TP 8
.B c
centimeters
.TP 8
.B i
inches
.TP 8
.B l
lines or characters (default)
.TP 8
.B p
PostScript points
.P
For example to print an image one inch high, you can specify height by
following options: \f3h1i\f1 (1 inch), \f3h2.54c\f1 (2.54 cm),
\f3h72p\f1 (72 points).
.RE
.TP 8
.B font
select current font. Escape's syntax is:
^@font{\f2fontname\f1}
where \f2fontname\f1 is a standard font specification. Special font
specification \f3default\f1 can be used to select the default body
font (\f3enscript\f1's default or the one specified by the command
line option \f3\-f\f1, \f3\-\-font\f1).
.TP 8
.B ps
include raw PostScript code to the output. Escape's syntax is:
^@ps{\f2code\f1}
.TP 8
.B shade
highlight regions of text by changing the text background color.
Escape's syntax is:
^@shade{\f2gray\f1}
where \f2gray\f1 is the new text background gray value. The default
value is 1.0 (white) which disables highlighting.
.SH PAGE DEVICE OPTIONS
Page device is a PostScript level 2 feature that offers an uniform
interface to control printer's output device. \f3Enscript\f1
protects all page device options inside an if block so they have no
effect in level 1 interpreters. Although all level 2 interpreters
support page device, they do not have to support all page device
options. For example some printers can print in duplex mode and some
can not. Refer to the documentation of your printer for supported
options.
Here are some usable page device options which can be selected with
the \f3\-D\f1, \f3\-\-setpagedevice\f1 option. For a complete listing,
see \f2PostScript Language Reference Manual\f1: section 4.11 Device
Setup.
.TP 8
.B Collate \f2boolean\f1
how output is organized when printing multiple copies
.TP 8
.B Duplex \f2boolean\f1

.TP 8
.B Tumble \f2boolean\f1
how opposite sides are positioned in duplex printing
.SH PRINTING EXAMPLES
Following printing examples assume that \f3enscript\f1 uses the
default configuration. If default actions have been changed from the
configuration files, some examples will behave differently.

A nice HTML report of your project's C source files.
.SH ENVIRONMENT VARIABLES
The environment variable \f3ENSCRIPT\f1 can be used to pass default
options for \f3enscript\f1. For example, to select the default body
font to be Times\-Roman 7pt, set the following value to the
\f3ENSCRIPT\f1 environment variable:
.TP 8
.B \-fTimes\-Roman7
.P
The value of the \f3ENSCRIPT\f1 variable is processed before the
command line options, so command line options can be used to overwrite
these defaults.
Variable \f3ENSCRIPT_LIBRARY\f1 specifies the \f3enscript\f1's
library directory. It can be used to overwrite the build-in default
`@prefix@/share/enscript'.
.SH RETURN VALUE
\f3Enscript\f1 returns value 1 to the shell if any errors were
encountered. On successfull termination, the return code is
constucted from the following flags:
.TP 8
.B 0
no errors or warnings
.TP 8
.B 2
some lines were truncated or wrapped
.TP 8
