You might have heard about the Cloud9 IDE. It's a collaborative development environment in the cloud. Having the Auto-Save and Auto-Merge turned on in the Preferences, it's almost as good as these web based tools which show all the cursors of the collaborators:
or these native ones:
# Get Rebol 2 curl -A '' -O http://www.rebol.com/downloads/v278/rebol-core-278-4-2.tar.gz tar zxvf rebol-core-278-4-2.tar.gz mv releases/rebol-core/rebol . rm -rf releases/ # Get Rebol 3 community build curl -O http://rebolsource.net/downloads/linux-x86/r3-g4d9840f # Get Rebmu curl -O https://raw.github.com/hostilefork/rebmu/master/mulibrary.rebol curl -O https://raw.github.com/hostilefork/rebmu/master/mushing.rebol curl -O https://raw.github.com/hostilefork/rebmu/master/rebmu.rebol # Try it! ./r3-g4d9840f -q --do 'do %rebmu.rebol rebmu [pr"HEllO, REBmu!"]'
But let's not just stop there! What if we can actually work the development of Red together?
git clone https://github.com/red/red cd red ../rebol --do 'do/args %red.r "%red/tests/console.red"'
and half a minute later you will get a Red prompt! (It takes the long only because at the moment it loads Red/System first into Rebol 2, then compiles the Red interpreter into Red/System for compilation or something like that :) The point is, it will improve a lot within a few weeks) Here is a screenshot:
