Convert TeX's pascal to javascript

web2js

This is a Pascal compiler that targets WebAssembly, designed specifically to compile TeX so it can be run inside the browser. More specifically, this repository includes a TeX engine called jsTeX which is like LuaTeX but instead of embedding Lua it embeds JavaScript.

Importantly, the jsTeX engine passes the trip tests which you can verify by running make test.

There is a live demo and a short overview available at

J. Fowler, Both TEX and DVI viewers inside the web browser, TUGboat, Volume 40 (2019), No. 1.

Prerequisites

This projects depends on NodeJS for executing the javascript. To post-process the WebAssembly, you will need wasm-opt on your path.

You will need a full TeX installation (e.g., TeX Live) with access to kpsewhich in order that library.js can find the necessary TeX files. You also need tie and tangle to turn the WEB sources into Pascal which can be fed to the compiler.

The contents of the texk, triptrap, and etexdir subdirectories were copied from tug.org via

mkdir texk
rsync -a --delete --exclude=.svn tug.org::tldevsrc/Build/source/texk/web2c/tex.web texk
rsync -a --delete --exclude=.svn tug.org::tldevsrc/Build/source/texk/web2c/triptrap .
rsync -a --delete --exclude=.svn tug.org::tldevsrc/Build/source/texk/web2c/etexdir .

Getting started

After cloning this repository, run npm install.

Then run

make core.dump

to apply the changefiles, compile the resulting Pascal source to WebAssembly, and run initex.js to produce a format file and its corresponding memory dump.

Then you can run TeX on a file called sample.tex with

node tex.js sample.tex

jsTeX

The main innovation of jsTeX is \directjs primitive similar to LuaTeX's \directlua. For example,

\documentclass[12pt]{article}

\newcommand{\cubeit}[1]{\directjs{
  tex.print('$');
  tex.print(`#1^3 = ${#1*#1*#1}`);
  tex.print('$');
}}

\begin{document}

Let's multiply eight by eight by eight.  \cubeit{8}

\end{document}

Inside \directjs, the JavaScript function tex.print can be used to emit strings back into TeX for further processing.

`Package pgf Error: Driver file pgfsys-ximera.def not found`

I'm trying to run make and get this error - I'm not sure if the def file is supposed to be in the texlive distribution - I've scoured everywhere but can't find it... Please could someone help thanks!

The current date is not displayed in the TeX banner

4 JUL 1776 is not the current date
It's just a default that Knuth left in tex.web for system-dependent changes to replace with a function for getting current date and time.

Cannot build the project due to missing Makefile target

Multiple problems building project:

For Makefile, target bigmem.ch does not exist, therefore does not compile.

Even if removing bigmem.ch and bigmem-changes.ch from Makefile, got a very obscure error in node compile.js (something about jump target label 9998 not found).

Hoping to use this in a project with circuitikz, would very much appreciate you checking this error out. I suspect perhaps you did not git add all your .ch files from local (specifically, bigmem.ch)?

I am running on Ubuntu with full TeXLive in case that helps.

Web deployment core.dump size

In your tikzjax project, you were able to deploy the core.dump file with only 500 KB of WASM. However, my core.dump is ~160MB due to the 2500 pages of memory. How did you have such a lightweight deployment package?

My goal is to enable circuitikz, amsmath, and siunitx support for tikzjax basically.

web2js's \openin or \ifeof don't work in the same way as the standard primitives

detailed documentation at StackExchange TeX question:
Where do I have to store “babel-latex.cfg” so “kpsewhich” can find it? What do I have to put in the file “babel-latex.cfg”?

Another thing, is there anything (legal or something?) stopping you from distributing the core.dump files etc.? If not, why not create Releases here on GitHub with the Files attached.
This would really help others use your Project!

Create Docker environment

web2js has some dependencies to produce core.dump. It is hard to setup the local environment, therefore I want the Docker environment.

This is my Dockerfile but ! I can't read TEX.POOL. error has occurred at node initex.js.

The following is that log.

! I can't read TEX.POOL.
[Object: null prototype] {
  '0': Memory [WebAssembly.Memory] {},
  getStackPointer: [Function: 20],
  setStackPointer: [Function: 21],

  asyncify_start_rewind: [Function: 388],
  asyncify_stop_rewind: [Function: 387]
}
! I can't read TEX.POOL.

This message is sent out from the source file but I don't know what is needed or wrong.
tex.pool file is certainly exist by tangle. How can I fix it?

eTeX instead of TeX => ! You have to increase POOLSIZE.

No problems if I take exactly your instruction steps:

1. tangle -underscore tex.web
2. ...
3. compile.js
4. initex.js

If I try with eTeX:

1. tangle -underscore tex.web etex.ch
2. renaming etex.src to plain.tex so the format file fits
3. ...
4. compile.js
5. initex.js
   => error:
   ! You have to increase POOLSIZE.

I have a TeX Live 2019 distribution under Windows 10, for more background of this issue see TeX SX: Detailed description of my case

Your example drawing a circle with TikZ works with eTeX:

This is e-TeX, Version 3.14159265-2.6 (preloaded format=latex 2019.2.23)

(sample.aux) ABD: EveryShipout initializing macros [1] (sample.aux) )
Output written on sample.dvi (1 page, 2976 bytes).

How to fix this?
What am I doing wrong?

I think my etex.ch file doesn't contain all necessary changes, e.g. memory managament pool_size ....

Do you have a working etex.ch or ready-to-use etex.web?
