Oyster is a forking server which remotely runs Perl code. It makes the program's STDIN and STDOUT available as Redis lists, and communicates with its frontend via Redis as well.
The upshot is that you can write naive Perl code and run it interactively in the browser. This doesn't simply eval code and print the output: you can accept textual input in real time. We think this is neat.
We have written an example web application using PocketIO; the relevant code is in app.psgi (and usage is below). It exists to showcase the current features of oyster. We encourage people to come up with their own frontends to oyster for any purpose they see fit.
First, install and run Redis. This is left as an exercise for the reader.Then, run oyster:
and technically you're done. But it's useless without a frontend interface.
We have a simple PSGI-based web interface. We recommend running with plackup, eg
plackup app.psgi -s Twiggy
Useful modules to have installed:
- Redis::Handle (Tron created this!)
- No code sanitation
- Had to turn off strict to get a pipe to the forked child.
