Hi,
yes, I can add a --safe command line option. Shared variables can
already be disabled with --noSV.

I can set it up for testing purposes. I already have
some servers available.
Would it be possible to add a flag that enables "safe
mode"? This would restrict the availability of shared variables
and native functions?

Hi Thomas,
nice idea, we should try that.
I believe that it should already be possible to start
GNU APL from eg. an apache web-server; the missing
piece could be the backward direction (user input ->
webserver).
Security should not be too hard on linux systems.
A problem remaining is where to host this in a permanent
fashion.
Probably the GNU project will not be too happy if we use their
capacity
for (possibly heavy) APL demos.

Hi,
it is well known that Dyalog APL and NGN APL both have an
online demo version
which is a very nice feature:
* for trying some quick idea when not at home;
* for letting other people discover GNU APL;
* for providing some kind of "permanent link" in forums,
etc. (for instance
on "golf" challenge forums;
* etc.
Both systems are quite different:
* Dyalog APL has a server-side software
* NGN APL has a client-side _javascript_ software
Of course, the server-side software needs some special care:
* security issues if the user is allowed to execute some
system commands;
* CPU/memory/time quotas
Wouldn't it be nice to have GNU APL providing its own
demo-version?
I browsed a little and found about Emscripten:
https://github.com/kripken/emscripten/wiki
https://github.com/kripken/emscripten/wiki/Tutorial
It looks like even some large projects could be "easely"
compiledinto _javascript_.
Do you think it would be easy to do it with GNU APL?
If someone is able to compile it to _javascript_, I could
perfectly write the HTML/CSS/_javascript_
web interface as a contribution.
Best regards,
