Posting-number: Volume 4, Issue 6
Submitted-by: "John Myers" <jgm at k.gp.cs.cmu.edu>
Archive-name: psinter-patch1
These patches make several bug fixes and enhancements to the Postscript
interpreter that was posted to comp.sources.unix. They include a
driver for X11 and some speedups that I picked up off of Barry Shein.
Please read the instructions at the beginning of each of the patches
before applying them.
Bugs fixed:
Half-implemented the missing operator "vmstatus". The number of savelevels is
correct (as far as the broken implementation of "save" and "restore" allow),
but the amount of memory used and free is a lie.
Implemented the missing operator "noaccess".
Fixed a bug in the operator "stopped". Previously it only worked on arrays,
but now it works on any executable object.
Fixed the parsing bug for reals with a trailing period (e.g. "4.") which
resulted in the "undefined in operater exec" errors reported to the net.
Changed an occurance of the variable "signed" to "signedp" as the former is an
ANSI C keyword.
Added a version of the missing file postscript/demos/buildcachefont.ps
Fixed operators kshow, translate, scale, rotate, reversepath
Casted NULL to appropriate type when it was passed as a parameter.
Removed unused variables.
The fourth parameter to the "framedevice" is no longer ignored. psrc
has been modified so that if a driver defines the postscript operator
"outputpage", it will be called instead of the "beep and wait for
input" routine when the copypage or showpage command is executed.
Enhancements made:
Macroized PanicIf()
Changed "undefined in operator exec" errors to instead report
"undefined in operator foo", where "foo" is the operator that was undefined.
Fixed imagemask to deal better with images that have to be shrunk. Bitmapped
fonts intended for 300 dpi printers look much better now.
(Change courtesy of Christopher Cox, cc4b at andrew.cmu.edu)
Tweaked makefile to deal better with sun3.
Added "getenv" operator. The syntax is:
<string> getenv <string> <true>
if the environment variable exists, or
<string> getenv <false>
if it does not.
Each driver must now define the character pointer "DriverType". The
value of this variable is placed in the string produced by the
"version" operator.
Added operators letter, note, and legal.
Barry Shein's speedups have been incorporated.
A version of the X11 driver is included.

XThis is a patch for Crispin Goswell's postscript interpreter, which
Xwas posted to comp.sources.unix a while back. If you don't have the
Xinterpreter, you can get it from one of the comp.sources.unix
Xarchives.
X
XSoon after the interpreter was posted, I posted these fixes to
Xcomp.sources.bugs, but they unfortunately had lines wrapped by our
Xmailer. This first patch is equivalent to that posting (modulo line
Xwrapping) and if you successfully applied that posting, you can skip
Xto the next patch.
X
XTo install this, you need the 'patch' program which is also available
Xfrom the comp.sources.unix archives.
X
XChange directories to the top-level postscript directory (the one with
Xthe file "MANIFEST" in it) and apply this patch with the command:
X
Xpatch -p0 <ps.diff.v1

XTo apply this, you need the 'patch' program which is available from

X
XChange directories to the top-level postscript directory (the one with
Xthe file "MANIFEST" in it) and apply this patch with the command:

X
X+ Version 2:
X+
X+ Bugs fixed:
X+
X+ Fixed operators kshow, translate, scale, rotate, reversepath
X+
X+ Casted NULL to appropriate type when it was passed as a parameter.
X+
X+ Removed unused variables.
X+
X+ Enhancements made:
X+
X+ Each driver must now define the character pointer "DriverType". The
X+ value of this variable is placed in the string produced by the
X+ "version" operator.
X+
X+ Added operators letter, note, and legal.
