Narwhal speed about coffeescript

[jashkenas]

Is coffee -i not working for you at all? On the latest 0.1.5? Let me know if it isn't.

So, the interactive mode is still a huge hack -- it's shelling out to the compiler (in Ruby) for every line you type, and then taking that JS back and evaling it. I wouldn't worry too much about the speed.

That said, the idea with Narwhal is to provide multiple backing engines that you can choose from. I haven't tried it, but I think you should be able to install the "k7" engine, which uses Google's V8, and get much faster script execution.

coffee --version
CoffeeScript version 0.1.5

coffee -i
require error: couldn't find "/Users/tbd/lib/coffee_script/narwhal/js/launcher.js"

if I add Dir.chdir(CS path) in command_line.rb:launch_repl then I get
require error: couldn't find "coffee-script"

narwhal was installed via source /Users/tbd/Software/narwhal/bin/activate

for now I created a command in TextMate CoffeeScript bundle to compile and run it in jsdb and I am happy ;)

Whoa. Thanks for the bug report -- coffeescript -i was completely broken when running outside of the coffee-script directory, and I never noticed. I've pushed out a 0.1.6 update that fixes the problem. Closing this ticket -- if it doesn't work for you, let me know.

problem fixed. thank you and keep up the good work !
