DESCRIPTION
Converts the specified file(s) containing C/C++ code to Postscript out‐
put conforming to the Adobe Structuring Conventions.
If no input file is specified then input is accepted from stdin. Post‐
script 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 directives Courier-BoldOblique
Comments Helvetica-Oblique
Strings Courier-Oblique
Keywords Courier-Bold
Line numbers Times-Roman
Types Courier-Bold
Function identificators Bookman-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 pre‐
processor variables in the command line. c2ps will neglect those
pieces of code that are cut out by the preprocessor given a set of men‐
tioned variables.
By default, on each column c2ps draws an alphabetic index of all func‐
tion 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 reencod‐
ing). 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 imple‐
mentor 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 accord‐
ing 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 posi‐
tion ( 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
