PARI in the browser, but served from a local Raspberry Pi?

["Georg.Fischer" <georg.fischer@t-online.de>]

Bonjour,

Neil Sloane's OEIS currently has 111610 PARI scripts.
I'm one of the OEIS editors, and I started to set up a
Raspberry Pi that offers a suite of math software packages
for testing program snippets in the OEIS.

Users should be able to test PARI (and other) scripts
from any device (Windows, Mac, Linux, Android) on the
local (W)LAN, without Internet connection, and without
installing the software packages themselves.

PARI/GP is running fine on the Raspi's commandline,
but I want to offer it by the Apache2 server on the Raspi
with a heavily stripped-down/modified version of your evaluation
page at <https://pari.math.u-bordeaux.fr/gp.html>.

What do I need?

Meilleures salutations - Georg
