Is there an Ada postscript package anywhere ?

Is there an Ada postscript package anywhere ?

[CSCI1E80]

I have to write a package that generates poscript output files to be printed
on a postscript printer. Has anybody out there ever seen or heard of one ?

Basically, what I have to do is to change font sizes before
making calls to text_io procedures.

I also have to figure out how to print in "Landscape" format.

If anybody knows where I can find a package that already incorporates
postscript, PLEASE PLEASE PLEASE let me know.

Thanks bunches,
John D. Smith

ftp.rational.com:/public/apex/freeware/ada_print.3.0.0.tar.gz for
landscape postscript printing of Ada source (in Ada, of course).

John Smith asks about generating postscript

the important thing to realize is that postscript is a full blown
programming language, so what you are generating is a program, it is
not some kind of simple markup language. Now you can write a postscript
program that will process ASCII, or marked up ASCII text, so one possible
form of output from a program generating postscript is:


   (postscript program)
   (marked up text)

where the postscript program reads the text as input.

Just amplification of the previous message --- the suggested form 
>    (postscript program)
>    (marked up text)
is in fact what nearly all postscript generating programs do.
(There are a few exceptions, but not many.)  So basically you 
do the following:
  * Design your own set of markup commands.  If your markup is not
    complex, this is nearly trivial.
  * Write a PostScript procedure for each markup command.  The
    difficulty of this part depends on the complexity of the markup,
    and on familiarity with the PostScript language. Steal this code
    or get someone else to write it if you can, but if you must it's
    not really hard.  You need the PostScript Tutorial and Cookbook 
    from Adobe Press, and the PostScript Reference Manual from same. 
    There are probably copies on a bookshelf near you. The third
    manual in the series, PostScript Program Design (I've probably 
    got that slightly wrong, since I'm relying on memory) is useful
    if you do anything large or intended for widespread distribution.
    For simple layout tasks, chances are you can lift much of the 
    code you need directly from the Cookbook section of the first
    manual.  
  * Write a tiny bit of code in Ada or whatever to emit the marked up
    text.  This is certainly trivial, unless one of the other two 
    steps was badly botched or you are doing something really fancy.
