supp-vis and pdfetex

[Patrick Gundlach]

Hello,

this is slightly off-topic:

when using supp-vis in a plain-tex document, it runs ok with normal
TeX, but not with pdfetex:

\input supp-vis
Hello \TeX!
\bye

--------------------------------------------------
Running `PDFTeX' on `test' with ``pdftex  "\nonstopmode\input test.tex"''
This is pdfeTeX, Version 3.141592-1.21a-2.2 (Web2C 7.5.4)
 \write18 enabled.
entering extended mode

Any way around this?

Hello Hans,

Looks fine with several different visualizations. Thanks.

Hello again,

for those who don't know supp-vis but know what glue and penalties
are: 

try \showmakeup and you get an idea where penalties, glue etc. are
inserted. This is a very cool debugging tool, because it (amazingly)
does not interfere (as far as I can see) with the actual layout.
