10.1, and some new stuff

10.1 is out. Nothing major, but it has some cleanups and bugfixes. It's worth switching to IMO.

Beyond that, 10.2 is being worked on. The development branches (now with live snapshots) has a .NET implementation of the VM, reduced memory requirements, new tools to shrink a saved image, and the start of a debugging tool (already capable of decompiling most compiled code). In the optional modules, I've started work on extending the compiler to generate smaller, faster code.

does>

A few days ago, someone in the IRC channel asked about implementing does>
The code below provides an implementation, though it does require my extensions
package to be loaded first.

                         ( it can be used by the .does class.                    )
    ['] .does compile    ( And finally, compile a call to the .does class, which )
                         ( will take care of compile-time and interpret-time bits)

Back on IRC

After a long break from IRC due to connectivity problems, I will now be back on a regular basis.

Even better, I now have an irc-via-email client, which means that I am now able to monitor the #retro channel continually throughout the day, so if you have questions, I'll be able to respond far more quickly.

Misc. Updates and an introduction to Motu

10.0 (Stable) has been out for a while now, and I'm nearing completion on 10.0.1 (documentation updates to cover missing words, a fixed version of ' and movement of a few state variables to specific places at the start of the image).

In addition, I've been working on reviving an app I first created back in the Retro 7 days. The current incarnation of this is Motu, a notepad with a Retro system built in. I used to use it to keep notes and bits of code I was working on together.

Motu is implemented as a client-side web app, storing data in a cookie, and allowing trial and debugging of code. I've tested it in Safari, FireFox, and Chrome. (It will *not* work in IE). Chrome users need to start Chrome with the --enable-file-cookies flag for this to work.

Motu uses a 10.0.1 (development) image, and needs access to the state variables I mentioned earlier (it uses them to allow resetting the image to a default state without a restart). 

You can get a copy of Motu from the git repository:

git clone git://github.com/crcx/motu
