NAME
trueprint - print program listings on postscript printer.
SYNOPSIS
trueprint [ options ] [ files ]
DESCRIPTION
trueprint is a general purpose program printing program. It tries to
produce everything that anybody could need in a program printout
without the need for large numbers of switches or pipelines. trueprint
can currently handle C, C++, Java, Perl, Verilog, shell (including
ksh), Pascal, pseudo C, report files (trueprint report file, see
NOTES), listing files, text files.
Each page in the output has a default header consisting of the date or
a user-defined string, the current function name, and the overall page
number (which is used in the indexes); and a footer consisting of the
date, the current file name and page number within file, and the
overall page number. If the language contains the concept of braces
then trueprint will include a braces depth count in the left-hand
margin.
The printout has two function indexes at the front - one is an
alphabetical list of all functions and the other is a list of files
with functions in each file in alphabetical order. The first is
suppressed if there are no functions and the second is suppressed if
there is only one file.
If no language is specified on the command line then options are
defaulted to be appropriate for the first file specified on the command
line. The filetype is taken from the suffix - valid suffixes are
Language Suffix language option
C .c .h -language=c
C++ .cxx .cpp .cc -langauge=cxx
.C .hpp .H
Java .java -language=java
Shell .sh -language=sh
Perl .pl -language=perl
Pascal .pas -language=pascal
Verilog .v -language=v
Pseudo C .pc .ph -language=pseudoc
Report format .rep -language=report
Listing .lst -language=list
Plain Text default -language=text
When Trueprint starts it uses four sets of options:
— Hard-coded defaults
— Language-specific defaults
— Options taken from the environment variable ‘$TP_OPTS’
— Command-line options
Each set of options overrides the earlier sets, so command-line options
override all other sets.
If you want to set some personal default options, then simply set the
environment variable ‘$TP_OPTS’.

USAGE
The usage of the ‘-D <string>’, ‘--debug=<string>’ is as follows:
Each letter turns on a set of debugging messages, and the corresponding
digit indicates the level of messages, with 1 indicating the least
number of messags and 9 turning on all messages. The letter ‘@’ can be
used to turn on all areas, so ‘--debug=@9’ will turn on all messages.
Use ‘--help=debug’ for details of what letters turn on what areas.
Note that this feature is not uniformly implemented - messages were
only typically added where they were needed. Also note that messages
will not be generated in code prior to the code that sets the debug
string!
The usage of the ‘-O <string>’, ‘--diff=<string>’ option looks as
follows:
You specify the old version of the file or files with
‘--diff=<pathname>’. If <pathname> suffixed with the current filename
is a valid file then the differences between <pathname>/<filename> are
displayed. Alternatively, if <pathname> is a file and you’re printing
one file, then the differences between <pathname> and the current file
are displayed. Examples how to make it are shown below:
trueprint --diff=../old- this.c that.c
will print the differences between ../old-this.c and this.c, and
../old-that.c and that.c.
trueprint --diff=../old/ this.c that.c
will print the differences between ../old/this.c and this.c, and
../old/that.c and that.c. Note that the trailing / is important.
trueprint --diff=this.c that.c
will print the differences between this.c and that.c.
The usage of the ‘-A <selection>’, ‘--print-pages=<selection>’ option
looks as follows:
<selection> consists of a comma-seperated list of page selections:
‘<number>’ -- print the specific page
‘<number>-<number>’ -- Print all pages between, and including,
the specified pages
‘<function-name>’ -- Print all pages that include function-name.
‘d’ -- Print all pages that have changed (this is only useful
with the ‘--diff’ (see above) option.
‘D’ -- Print all pages containing functions that have changed
(this is only useful with the ‘--diff’ (see above) option.
‘f’ -- Print the function index
‘F’ -- Print the file index.
For example,
--print-pages=1-5,main,f
will print the function index, pages 1 to 5, and all the pages for the
function ‘main’.
If you specify ‘--prompt’then trueprint will prompt you for each page,
whether or not it should print that page. It will give you information
such as the current filename, current functionname, page number, and so
on. The possible responses are:
‘y’ -- Print this page.
‘y<number>’ -- Print <number> pages.
‘y*’ -- Print all the remaining pages.
‘n’ -- Skip this page
‘n<number>’ -- Skip <number> pages.
‘n*’ -- Skip all the remaining pages.
‘p<selection>’ -- Print all remaining pages that match
<selection>, where <selection> is in the format defined above.
‘?’ -- Print a help message.
The ‘--message=<string>’ option takes a few % escapes for <string>
which are listed below:
‘%%’ -- Print a simple %.
‘%m’ -- Print the current month of the year as a number, e.g.
05.
‘%d’ -- Print the current day of the month, e.g. 01.
‘%y’ -- Print the current year, e.g. 1999
‘%D’ -- Print the date in the format mm/dd/yy.
‘%L’ -- Print the date and time in long format, e.g. Fri Oct 8
11:49:51 1999
‘%c’ -- Print the last modified date of the current file in the
format mm/dd/yy.
‘%C’ -- Print the last modified date and time of the current
file in long format, e.g. Fri Oct 8 11:49:51 1999
‘%H’ -- Print the current hour.
‘%M’ -- Print the current minute.
‘%S’ -- Print the current second.
‘%T’ -- Print the time in the format HH:MM:SS.
‘%j’ -- Print the day of the year, e.g. 095.
‘%w’ -- Print the day of the week, e.g. Sunday.
‘%a’ -- Print the
abbreviated day of the week, e.g. Sun.
‘%h’ -- Print the abbreviated month name, e.g. Mar.
‘%r’ -- Print the time in am/pm notation, e.g. 10:45pm.
‘%p’ -- Print the page number in the current file.
‘%P’ -- Print the overall page number.
‘%f’ -- Print the total number of pages of the current file.
‘%F’ -- Print the total number of pages.
‘%n’ -- Print the current filename.
‘%N’ -- Print the current function name.
‘%l’ -- Print the username of the current user.
Default Values are:
‘left-header’ ‘%L’
‘center-header’ ‘%N’
‘right-header’ ‘Page %P of %F’
‘left-footer’ ‘%L’
‘center-footer’ ‘%n %p’
‘right-footer’ ‘Page %P of %F’
NOTES
For most of the languages, trueprint uses the language to work out
where comments are (so it can print them in italics) and where the
function names are (so it can print them in bold and include them in
the function index). However there are some special features for some
of the languages:
Pseudo C is like C, except it has a more forgiving syntax. In
particular it ignores strings, so if you leave off a closing quote then
pseudo C will print out using a vaguely sensible format. Pseudo C is
intended for printing code that doesn’t yet compile.
Listing format assumes very wide lines and a fixed page length of
sixty-six characters, so it turns off line-wrap and sets the page
length appropriately.
Report format uses a few special characters: anything between ^A and ^E
is printed in bold and included in the function index, and anything
between a pair of ^Cs is printed in italics.
ENVIRONMENT
By default Trueprint uses environment variables and the current
username.
PRINTER
Specify the printer to use when sending postscript output to the
printer.
TP_OPTS
Specify options. These options override any default options
including language defaults, but are overridden by command line
options.
TP_DIFF_CMD
Specify the diff command to be used. The command must produce
output in the same format as the classic Unix diff. This
variable can be used to add flags to the diff command used, for
example to make diff ignore whitespace.
TP_PRINT_CMD
Specify the print command. The default is lpr. If this is set
then it should be set to a command that takes standard input.
If this is set then the destination and number of copies have no
effect, i.e. there is no mechanism to pass these values to your
print command. If you set this to /bin/cat then the postscript
output will appear on stdout.
TP_PRINTERS_FILE
Specify the printers file. The default is the printers file
that was initially configured when trueprint was installed.
This can be used to test out a new printers file.
