[NTG-context] Makempy ...

However I get no output with ConTeXt MKIV ver: 2012.01.02 21:59 When processing the file with MKII there is a fatal error, which is after stoptext in the attached test-file.

Hi Hans, thank you for your immediate reply.

Re: [NTG-context] makempy (pstoedit - gs) hangs
Hallo!
I think I've identified the problem: in the PostScript prologue
file for
pstoedit you find the following bit of code (slightly simplified):
/getorigfont
{
dup /OrigFont known
{
/OrigFont get getorigfont
}
if
}
def
I guess anyone, even not familiar with PostScript, can spot the
error here:
getorigfont is called recursively ad infinitum! I have no idea why
this is so,
but this mistake is easy to correct, by simply commenting out the
innermost
?getorigfont?; and it indeed fixes the problem with Wolfgang's
code.
Why the error wouldn't happen with older versions of gs isn't
clear to me and
I haven't tested it (for debugging I used pstoedit 3.44 and gs
8.56
throughout); on the other hand, it's quite clear why the bug
wouldn't show up
on code that uses only outlines and no font, like in the last
example of
http://wiki.contextgarden.net/User-Defined_Enumerations as George
pointed out:
the spurious piece of code is only used for font redefinitions and
is therefore
not called in the case of the fuzzy itemize style, because the
symbols are not
taken from a font.
For people wanting to compile an amended version of pstoedit, the
attached
patch should do the trick, although hand-editing the relevant file
(src/pstoedit.ph) should be just as easy (this is really a 2-byte
patch ? and
you can even turn it into a 2-bit patch ;-).
Thank you Arthur!
I have patched 'pstoedit.dll' version 3.44 (0x6B674: 0x20 -- 0x25)
and so it works with gs 8.57 for me!

That's what I thought too (even if the bug had nothing to do with that
apparently). I wonder if all that is really needed and if it wouldn't be
simpler and less error-prone to use a custom dictionary where all the
overriding functions are defined. Instead the author of pstoedit does quite
scary things with systemdict ...
Maybe it is time for ghostscript to get
an mpost driver.
Sure, wouldn't harm either.

Don't know if this matters! But the temporary created pdf (input for
pstoedit) is a bit smaller then the string to render '123'. The
overshut of the round charakters '2' and '3' is cut.
try \ruledhbox{...} and you will observe similar effects, traditional
tex has alimited number of heights and depths for fonts and glyphs
themselves may have a practical boundingbox different from the tight
fitting one; just add struts or enlarge the box

I've written to the author of pstoedit exactly two years ago, when
pstoedit v. 3.40 was indeed broken (approved by the author). He sent
me a patch, but I didn't know how to compile the program, and I never
tested it since then.
Hans claimed that version 3.33 worked for him (and others approved
that downgrading worked), but it didn't work for me, since I would
need an older GS version as well.
Here some infinite loop occurs when I call
pstoedit -ssp -dt -f mpost mpy-bla-mpgraph.pdf mpy-bla-mpgraph.tmp
(which is what ConTeXt does in line 328 of makempy.pl)
I have no dea whether that's pdtoedit's or ghostscript's problem. I
hope that the author of pstoedit will reply and figure out what the
problem could be.
