#22Anyone got it working?
I managed to compile both build/circa and build/circa_d (build/circa_t is broken).
circa ➤ export CIRCA_HOME=`pwd`
~CIRCA_HOME ➤ export PATH=$PATH:$CIRCA_HOME/build
~CIRCA_HOME ➤ python tools/prebuild.py
~CIRCA_HOME ➤ scons build/circa build/circa_d
~CIRCA_HOME ➤ tools/ca-tests.py
Ran 105 tests, 0 failed, 11 disabled.
Am I missing something?

#23Significant whitespace in a live coding language? I like and use Python, but that seems like a show-stopper of a bad idea for a language designed for throwing code around in real time.
Can you expand on this? If I get my indentation wrong then it will be obvious very quickly. I'm guessing that it will only update if the basic syntax is correct though.

#24I really like this! One thing that wasn't shown is having variables in the CPP code get modified from in game. Would that be possible?

Not if the language allows you to mix tabs and spaces; in that case semantic details can be invisible.

#26Anyone got it working?

But I can't launch the repl (circa_d --repl) nor get any…
For the repl, can you try "circa_d -repl" (one dash instead of two)?
There is definitely some breakages in there, and most of those samples won't run currently. I'm rewriting the app that runs things in a graphical shell and I hope to have that ready soon. If you are feeling brave, you can go back in time to use Plastic (the SDL-based shell that I was relying on for a while). Instructions for that:
Checkout revision efb5300
Delete the files at src/generated/*.cpp and run prebuild.py again
scons build/plas_r (this will require SDL)
Launch with: build/plas_r samples/asteroids.ca (or some other sample)

#27I really like this! One thing that wasn't shown is having variables in the CPP code get modified from in game. Would that be possible?
Definitely possible, though you would store those tweakable variables in special MyVariable objects (rather than have them be normal C++ variables). With Circa you could grab the object that holds then variable's data, and then have C++ code that reads it as often as you want.
Game devs love to have tweakable variables, so there's a lot of libraries that will help with this. One example: http://www.antisphere.com/Wiki/tools:anttweakbar

#28I always wonder why so many languages eschew multiline comments. Is it monumentally harder to make a parser that supports it or is this a conscious decision?
It's not too hard, it was just a combination of laziness plus not being able to decide on a multiline comment syntax that looks nice. Anyway I just added it, using {- and -} separators (as in Haskell)

Ah, interesting :-)
I was just curious since there seem to be a few languages that only have single line comments. But usually it just results in people finding "hacks" so they can make them anyway (like Python's doc-strings) which just ends up being uglier than supporting them natively.

#30How can you have a website displaying a live-coding language, without a video displaying someone actually live-coding? :P Seriously though, I'd love to see a video of someone doing live-coding. I've been looking for a good live-coding environment ever since I found fluxus[1], and subsequently found out that development of it had stopped. [1] http://www.pawfal.org/fluxus/
Why would you think development of fluxus "has stopped"? The mailing list [1] is active enough for such a minority project, and the git repo [2] shows a reasonable activity for a mature (i.e. "done") project, with functionality commits from October last year, and French localisation commits from April this year (last one on the 19th, so less than 24h ago). [1] http://lists.pawfal.org/pipermail/fluxus-pawfal.org/ [2]…
I say its stopped because it is lacking a lot to get it working on OS X, so its not "done", and the latest release is for 10.5
