Purifyeps under Win32/fpTeX-- Problem and workarounds
Peter Denisevich
under Windows 2000. I ran into problems involving the TEMP
environment variable -- on my system the default tempdir is the
horrible:
C:\Documents and Settings\Peter Denisevich\Local Settings\Temp
which is referenced by the environment variable
TEMP=C:\DOCUME~1\PETERD~1\LOCALS~1\Temp
Purifyeps chokes on this as follows:
F:\home\pdenis\mp>purifyeps.pl t.eps t1.eps

Is this expected MetaPost behavior, a Web2C problem, something
specific to this build, or what? (Note that my METAFONT doesn't
work on such filenames either, though TeX does...)
In the meantime I can get around it at least for my single-user
home system either by defining another temp directory (set
TMPDIR=f:\temp) but I'm not sure this is portable to multiuser
Win2K/XPsetups. Or I can edit the purifyeps Perl script to write
its temp files to the current directory where the purified eps
file is to be output (replacing both occurences of
File::Spec->tmpdir() with "\.") -- this *looks* safe from what I
can make of the Perl.
Comments (in addition to curses at Bill Gates)?

I'd suspect an fpTeX problem, as I can't reproduce it on Win32/MikTeX
(which does not use Web2C):

Mine (same version) adds this:
kpathsea: Illegal fontname 'test?1.eps': contains '?'
And putting "input test~1.eps" in an mp file causes no problem.
Nor does running
mpost
and then typing test~1.mp at the ** prompt.
It would appear that the problem happens somewhere between the
command line and the call to the kpathsea routines.
If it will help any one, here is a portion of the output of
mpost --kpathsea-debug=5 test~1.mp
It shows tha first instance of the correct filename through the
first instance of the mangle version:
kdebug:kpse_normalize_path (.) => 0
kdebug:kpse_normalize_path (.) => 0
kdebug:kpse_normalize_path (.) => 0
path . is a directory
kdebug:kpse_normalize_path (./test~1.mp) => 0
kdebug:fopen(./test~1.mp, r) => 0x7c38b548
kdebug:fclose(0x7c38b548) => 0
kdebug:kpse_normalize_path (c:/TeX/texmf-var/web2c) => 3
kdebug:kpse_normalize_path (c:/TeX/texmf-local/web2c) => 3
kdebug:kpse_normalize_path (c:/TeX/texmf/web2c) => 3
kdebug:kpse_normalize_path (c:/TeX/texmf/web2c/cp8bit.tcx) => 3
kdebug:fopen(c:/TeX/texmf/web2c/cp8bit.tcx, r) => 0x7c38b548
kdebug:fclose(0x7c38b548) => 0
kdebug:kpse_normalize_path (.) => 0
kdebug:kpse_normalize_path (./mpost.mem) => 0
kdebug:kpse_normalize_path (c:/TeX/texmf-var/web2c) => 3
kdebug:kpse_normalize_path (c:/TeX/texmf-var/web2c/mpost.mem) => 3
kdebug:fopen(c:/TeX/texmf-var/web2c/mpost.mem, rb) => 0x7c38b548
kdebug:fclose(0x7c38b548) => 0
kdebug:kpse_normalize_path (.) => 0
kdebug:kpse_normalize_path (./test?1.mp) => 0
I thought cp8bit.tcx might be the culprit, but TeX uses the same
file and it ends up with the correct filename throughout the
corresponding debug output.

It should be OK.
I have always set TEMP (as well as HOME) to a pathname without
spaces. It was bad enough that Windows 95 put programs in
"Program Files", but WinXP putting everyone's temp and home directories
under "Documents and Settings" was a new level of evil.

Since you ask for comments "in addition to curses", here are my
required curses:
May he be condemned to use Windows software through eternity
_without_ any help from his employees at Redmond.
May he be required to apologize to Windows users for eternity
(or until all forgive him, whichever is soonest).

Thanks, Dan and Scott for your help. I'll send a copy of this to
Fabrice via the fpTeX mailing list.

I can confirm that part of the problem is a bug in fptex. The support
for file names with spaces is broken for mf.exe and mpost.exe. Sorry
for that. It is fixed in my build tree and I will make new binaries
available.
May I also remember people that win32 filenames shouldn't be \input
into tex with the usual windows syntax because \, ~ etc. are or maybe
active chars interpreted by tex. So the syntax to use would rather be:
c:/documents and settings/user/local settings/temp/...
