[Reduce-algebra-developers] Web REDUCE

[Francis W. <f.j...@li...>]

I have updated the Web REDUCE<https://reduce-algebra.sourceforge.io/web-reduce/about.php?start> framework to provide initial support for plotting using a version of Gnuplot compiled to WebAssembly, as for REDUCE itself. This is based on work by CD Clark III<https://github.com/CD3/gnuplot-in-the-browser> and work by Hermann Rolfes<https://github.com/kungfooman/WebREDUCE/>. There is a separate button to start desktop REDUCE with plotting, partly because plotting requires additional resources. Currently there are some restrictions:

  *   only the last plot is visible since each plot overwrites any previous plot;
  *   plotting can cause spurious end-of-file warnings and fatal end-of-file errors;
  *   mobile Web REDUCE does not support plotting.

I had hoped to update the version of REDUCE itself, which is getting a bit out of date, but I have run into some problems, so I will do that later.

If you want to try plotting in Web REDUCE<https://reduce-algebra.sourceforge.io/web-reduce/about.php?start>, you should be able to copy and paste all the examples in the manual, GNUPLOT: Display of Functions and Surfaces<https://reduce-algebra.sourceforge.io/manual/manualse116.html#x151-27700018.1>, (one at a time!) and they should all work. If you run into any problems  please let me know.
