[toronto-lisp] Interesting video of a new visual programming tool

[Vishvajit Singh]

Hello,

Today I watched this interesting video created by a researcher at MIT
CSAIL. It describes a new programming language and environment called
"Subtext":

http://subtextual.org/subtext2.html

It appears to be a sort of Lisp structure editor, mixed with the idea
of pattern-matching on the arguments using truth tables.

You have to watch until near the end to see a really complex
application of the tool. He develops a function that determines the
"attack damage" in a role-playing game, and it's really nice the way
you can literally see how the data flows through your program.

I really wanted to get my hands on it, so I downloaded the ZIP file on
his website (http://subtextual.org/subtext2.zip), but it appears to be
a Windows app so I'm not able to play with it right now.

It's interesting to see that even 50 years after Lisp was invented,
people are still trying to figure out how to get visual programming
right. It seems that there are still many possibilities to be explored
in this space.
