web/rest server in scheme (chibi-scheme)

Introduction

presto is basically a very basic, ad-hoc, extendable, web and rest-api-server implemented in chibi-scheme. Maybe one day it will grow up to be something more.

Dependencies:

• chibi-scheme: http://synthcode.com/scheme/chibi

Execution:

$ export CHIBI_MODULE_PATH=$CHIBI_MODULE_PATH:`pwd`/src/main
$ chibi-scheme -r src/main/boot.scm

The environment setup has been put in setup.sh which you can source for simplicity.

$ . setup.sh
$ chibi-scheme -r src/main/boot.scm

Sourcing setup.sh and starting presto (as boot.scm) has been put in presto.sh, so you don't even have to source setup. You can just run presto.sh.

$ ./presto.sh

Now that presto is running, point a browser to http://localhost:1080/.

Testsuite:

Tests are in src/test/ and can be run directly with chibi-scheme, e.g.:

$ chibi-scheme -r src/test/parse-test.scm

You can also point a browser to http://localhost:1080/testsuite to run the full test set and see the output in the browser together with timing info.

Projects & Development

The development of this project is at the moment driven by the development of https://github.com/RosenborgSupporterSoftware/storkar, which is based on a front-end architecture style I am familiar with from work projects, but here with presto as the scheme-based, written-from-scratch, back-end. It is also driven by my desire to elevate my scheme-programming skills from a quite basic level to advanced.

When this front-end is fully functional, focus will return to this back-end to explore some areas of interest. One plan is to make the request handling workflow actor-based (like akka actors) in some way or other, to really make request-handling scalable. I also want to support things like websockets. With more robustness and a more serious approach to standards compliance, presto could end up being a very scalable and usable, fun little project.
