copied!<p>I believe <strong>Common Lisp</strong> should suit your needs. I always have some code in my SLIME/Emacs session that wouldn't compile. You can always tweak things, redefine functions in run-time. It is actually very good for prototyping.</p> <p>A few years ago it took me quite a while to learn. But nowadays we have quicklisp and everything is so much easier.</p> <p>Here I describe my development environment: <a href="https://stackoverflow.com/questions/6546834/install-lisp-on-my-linux-machine/6548692#6548692">Install lisp on my linux machine</a></p> <p>PS: I want to give an example, where Common Lisp was useful for me: Up to maybe 2004 I used to write small programs in C (the keep it simple Unix way).</p> <p>The last 3 years I had to get lots of different hardware running. Motorized stages, scientific cameras, IO cards.</p> <p>The cameras turned out to be quite annoying. Usually you have to cool them down to -50 degree celsius or so and (in some SDKs) they don't like it when you close them. But this is exactly how my C development cycle worked: write (30s), compile (1s), run (0.1s), repeat.</p> <p>Eventually I decided to just use Common Lisp. Often it is straight forward to define the foreign function interfaces to talk to the SDKs and I can do this without ever leaving the running Lisp image. I start the editor in the morning define the open-device function, to talk to the device and after 3 hours I have enough of the functions implemented to set gain, temperature, region of interest and obtain the video.</p> <p>Then I can often put the SDK manual away and just use the camera.</p> <p>I used the same interactive programming approach when I have to parse some webpage or some weird XML. </p>
