tex--'s Issues

Include tangle (or build instructions) in web

Bryan,

first of all, thanks for the amazing job!

I just tried to rebuild tex.p from tex.web/tex.ch (to increase TeX's constants further) by running $ ./tangle tex.web tex.ch with a tangle I built from a kertex distribution. My tangle does not recognize the underline option, however, thus stripping out all underscores, which consequently breaks tex.sh (expecting identifiers with underscores).

Can you please either include the tangle binary in the repo, or add instructions on how to build tangle from some TeX distribution?

many thanks,
Karl

Test on Mac OSX 10.9

Hi there, I just test the project on Mac OSX 10.9, it works very well.

The only problem is that tex.pool is not found under tex/, maybe it should be moved from web/ to tex/, otherwise the program utters:

$ ./a.out test.tex 
! I can't read tex.pool.

I want to port this to iOS and Android so that I can compile TeX scripts to get some images of formula. So I need to convert the .dvi files to .png or .svg, I'm currently investigating dvisvgm and dvipng, do you know any other better options?

Thanks.

TeX fails when given non-ASCII paths.

Specifically, TeX goes out of its way to detect non-ASCII paths and returns with an error: ! Text line contains an invalid character.

Loading tex.hpp problem

Hi there, I'm trying this project out. I tried to load tex.hpp with g++ -std=c++11 but received several errors. I'm using fedora and the version of my compiler:

$ g++ --version
g++ (GCC) 4.8.2 20131212 (Red Hat 4.8.2-7)
Copyright (C) 2013 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

My ultimate goal is to port this to mobile platforms, and I want to make sure this solution works. Which platform did you use to test things out?

Example on how to use with LaTeX

Do you have a simple example on how you intend people to use TeX-- with LaTeX? Is the idea to overload the tex class similar to what you did with plain?

DVI output incorrect.

Consider for example the simple tex file:
test.tex with content:
"
This is \TeX
\end
"

DVI output generated by TeX-Live:

DVI output generated by the program:

These HEX 0D (corresponding to unsigned int 13) should not be there. For some reason when Font Def 1(DVI command 243) gets executed the program adds this hexadecimal in the dvi, causing the DVI to be improper DVI output.
