Just wondering whether the repo contains e-tex supports?

Cheers

There are some very minor differences between the DVI files generated by rsTeX, and those generated by the tex that comes with TeX Live. They do not seem to affect the generated output itself in any visual way (at least, as tried with a book-length .tex file), but the DVI files differ.

I plan to look at this later, but just documenting this here for now; hope you don't mind. The “error” may well be in the tex output (I know the implementation in TeX Live makes some changes and is not 100% true to the Pascal code in tex.web.) A difference shows up in this minimal example, say test.tex:

\input plain

Now the good news: straightforward text

\end

The difference seems to be (using dvitype and diffing the output) is that the rsTeX-generated DVI file contains a right3 instruction (opcode) where the tex one contains a w0 (and this shifts some future bytes).

These are the commands I'm using to compare them (./a.out is rsTeX):

tex -ini test.tex
mv test.dvi test-TeX.dvi
mv test.log test-TeX.log
dvitype test-TeX.dvi > test-TeX.dvi.txt

./a.out test.tex
mv test.log test-rsTeX.log
mv test.dvi test-rsTeX.dvi
dvitype test-rsTeX.dvi > test-rsTeX.dvi.txt
