Hi All,
Context: Thanks to developments in the JavaScript world, we can now
run Python in the browser. See the projects emscripten
<https://emscripten.org/>, Pyodide <https://pyodide.org/en/stable/>,
and JupyterLite
<https://jupyterlite.readthedocs.io/en/latest/>/Pyolite
<https://jupyterlite.readthedocs.io/en/latest/kernels/pyolite.html>
for more about this. Essentially, modern web browsers are capable of
running the real CPython interpreter, and not only that but most
pure-Python packages can be imported
<https://pyodide.org/en/stable/usage/api/micropip-api.html> and run
without issues!
Several SymPy users proposed the idea of using this new functionality
to create a new SymPy shell that runs in the browser. I'm happy to
announce this idea is now a reality. Navigate to this URL
*https://www.sympy.org/en/shell.html* to check it out.
Some notes, in point form, about this project:
* based on latest version of SymPy (the version on pypi)
* initial load takes between 15 and 30 seconds (on desktop)
* running commands is very fast after initial load
* supports modern web browsers like Firefox and Chrome
* works on some mobile browsers (more testing needed)
Many thanks to Jeremy Tuloup who showed how the JupyterLite REPL can
be customized to create a SymPy shell.
The new SymPy shell on the sympy.org website is an experiment that
allows us to test the new JupyterLite-based REPL and iron out any edge
cases, with the goal of eventually using the same approach on
https://live.sympy.org/ (which has been becoming increasingly
difficult to maintain and keep up to date).
I invite you all to try out the new shell
<https://www.sympy.org/en/shell.html> by running your favorite SymPy
calculations (see bit.ly/sympyjstest <https://bit.ly/sympyjstest> for
examples). If you encounter problems, bugs, or other unexpected
behavior during testing, please add a comment to this issue:

I tried a simple indefinite integral - integrate(sin(x**3),x). This
displayed beautifully, but I discovered that I could not click on the
command I'd just entered to alter it. I guess this is a limitation of
the implementation, but I thought I'd point this out.
