SYNOPSIS

c2ps [ -?h124abceikmnruvwx ] [ -F defaultfont ] [ -C commentfont ] [ -K keywordfont ] [ -N lnumberfont ] [ -P preprocfont ] [ -S stringfont ] [ -T typefont ] [ -U functionfont ] [ -X nonlatinfont ] [ -d dim ] [ -f fontsize ] [ -l lines ] [ -p paper ] [ -o outputfile ] [ -s space ] [ -t tabsize ] [ -_ fun_highlight ] [ -DPREPROC_VAR ... ] [ -UPREPROC_VAR ... ] [ file ... ]

DESCRIPTION

Converts the specified file(s) containing C/C++ code to Postscript output conforming to the Adobe Structuring Conventions.

If no input file is specified then input is accepted from stdin. Postscript output is directed to stdout unless you specify an output file. The actual output page may be out with one, two or four columns.

Supported paper types are A4 and Letter.

Tabs in the input stream are expanded (by default) by blank characters to the closest modulo 8 position. You can specify your own constant number of blanks different from 8 for a tab to expand.

A formfeed (^L) character makes the converter move to the next column.

By default, C/C++ constructs are highlighted with following standard fonts presented on every Postscript printer:

     Preprocessor directivesCourier-BoldOblique

     Comments              Helvetica-Oblique

     Strings               Courier-Oblique

     Keywords              Courier-Bold

     Line numbers          Times-Roman

     Types                 Courier-Bold

     Function identificatorsBookman-LightItalic

The rest is printed with Courier (default font). If highlighting is disabled only the default font is used to print the read code (but not line numbers).

Comments may be printed dimmed to a configurable degree in a way that allows reader to concentrate mainly on the source itself referring to comments only when needed.

c2ps has basic preprocessor capabilities. You may define/undefine preprocessor variables in the command line. c2ps will neglect those pieces of code that are cut out by the preprocessor given a set of mentioned variables.

By default, on each column c2ps draws an alphabetic index of all function id definitions with locations, scanned from the beginning of the file being printed. As the number of these id’s grows the font used to print the index may get smaller in order to accommodate all the entries.

Occasionally, function index is drawn upon already printed source code. To cope with this you can either cancel the index option or use smaller fonts.

All the read symbols with codes 128..255 (0x80..0xff) are printed escaped so that c2ps output is all clean 7-bit ascii and can be sent over the Internet without uuencoding.

You can easily print source including fragments in Cyrillic, Hebrew, Arabic etc. which may be found in string and/or comments if you’re printing C/C++ code and anywhere otherwise. You just need a postscript font with encoding corresponding to the one that is used in the above fragments. If there’s no suitable built-in font in your PS printer you will have to prepend one to c2ps output.

If the symbols from the both halves of the code table are implemented in your PS font, you may simply use it to print any constructs that include 8-bit text (don’t forget to disable ISO Latin 1 font reencoding). Otherwise, with only upper half symbols (with codes > 127(0x7f)) implemented, there is an option to set a font to print specifically these symbols leaving the rest to be printed by either default or newly set fonts.

Also, as much as we know there exists a version of c2ps modified to support Chinese (Hanja) and Korean (Hangul). An address of the implementor is on the c2ps web page.

This is a manual page for c2ps ver4.0

OPTIONS

-? -h Print usage message.

-1 Specify single column per page output - default (portrait).

-2 Specify two columns per page output (1/2 size, landscape).

-4 Specifiy four columns per page output (1/4 size, portrait).

-a Disable adjusted multiple lines comments printing.

-b Disable drawing a box containing alphabetic index of functions scanned from the beginning of the file.

-c Disable C/C++ construct highlighting.

-e Disable printing entry/exit function name in the column’s header.

-i Disable ISO 8859-1 (ISO Latin 1) character encoding.

-k Use standard set of keywords rather than extended one.

-m When printing a file use the date of printing instead of file’s last modification date.

-n Disable line numbering.

-r Draw a frame round each column.

-u Disable drawing header at the top of each column.

-v Print current version.

-w Disable wrapping too wide lines onto following lines. Note, that when wrapping is enabled the maximum number of characters in line printed with any font is the number of the same point size Courier characters that may appear in single line without crossing column’s border.

-x Automatically toggle C/C++ highlight flag for each file according to its extension. ( Applicable extensions include .c .h .cc .hh .cpp .hpp )

-F defaultfont
  Use defaultfont as default font.

-C commentfont
  Use commentfont to print comments.

-K keywordfont
  Use keywordfont to print keywords.

-N lnumberfont
  Use lnumberfont to print line numbers.

-P preprocfont
  Use preprocfont to print preprocessor directives.

-S stringfont
  Use stringfont to print strings.

-T typefont
  Use typefont to print types.

-U functionfont
  Use functionfont to print function identificators being defined.

-X nonlatinfont
  Use nonlatinfont to print all symbols with codes > 127(0x7f). ISO Latin 1 encoding is automatically cancelled.

-d dim Print comments dimmed with the coefficient dim.
( black: 0.0 <= dim <= 1.0 :white ). Default is 0.75. So you can actually get rid of the comments in your printout by setting dim coef. to 1.0

-f pointsize
  Use pointsize -scaled fonts ( 10 - default ).

-l lines Make converter start a new column after each set of lines printed lines. You may want to use the resulted at the bottom of the column white space for notes if the space on the right is not sufficient.

-p paper Paper type specification ( A4 - default, Letter ).

-s points Leave points * 1/72 inch space between lines ( 0.0 - default ).

-t tabsize
  Expand each read tab with blanks to a next modulo tabsize position ( 8 - default ).

-_ fun_highlight
  Specify function id highlighting type ( none, box, underline - default ).

-DPREPROC_VAR
-UPREPROC_VAR
  You may define or undefine preprocessor variables in a standard compiler option fashion.

Below:
+/-: printed/not printed by c2ps
column 1: for variable X not mentioned in command line
column 2: for variable X defined
column 3: for variable X undefined

 1  2  3
 +  -  -  #ifdef X
 +  +  -   C/C++ code (+ preprocessor directives)
 +  -  -  #else
 +  -  +   C/C++ code (+ preprocessor directives)
 +  -  -  #endif

Similarly for #ifndef, just switch columns 2 and 3.

EXAMPLES

Multiple files
c2ps *.c *.h | lpr

Ordinary text
c2ps note.txt -c -n -u > note.ps

ISO Latin 1 font reencoding by default
c2ps -2 -c -n -F Times-Roman german.txt > german.ps

A different look
c2ps -F Times-Roman -C Palatino-BoldItalic -K Times-Bold
-N Helvetica -P Helvetica-Bold -S Times-Italic
-T Times-BoldItalic -_ box -w sample.c > sample.ps

An option set looking better on low resolution printers
c2ps -d 0 -C Palatino-Italic main.cc > main.ps

Partial preprocessing, selective printing
c2ps -DDEBUG -DSUN_SPECIFIC -UPRINT *.cc | lpr

Temporarily commented out code (still looks like a part of the code but a little bit dimmed)
c2ps -C Courier -d 0.5 temp.c -o temp.ps

Getting rid of comments
c2ps -_ box -d 1 main.cc | lpr

Printing 8-bit text (e.g. Cyrillic, koi-8 encoding)
c2ps -i -C Antique-Italic -S Antique koi8.cc > tmp
cat Antique-Italic.pfa Antique.pfa tmp | lpr

c2ps -i -c -n -F Antique koi8.cc > tmp
cat Antique.pfa tmp | lpr

c2ps -X Cyrillic-Italic-koi8 koi8.cc > tmp
cat Cyrillic-Italic-koi8.ps tmp | lpr
