Can't get CoffeeScript mode to work.

JamesWlf

I'm using Processing 2.2. I have already installed and uninstalled twice. :S

GoToLoop

Does JavaScript Mode fail too? Can you at least run any CoffeeScript Mode's bundled examples?

JamesWlf

Javascript seems to work fine. And no, I can't even run the examples in CoffeeScript Mode. :S

GoToLoop

Does the CoffeeScript Mode show up for selection along the others?
The other option is manually downloading it from the link below:
https://github.com/fjenett/coffeescript-mode-processing/archive/master.zip

• Open it and go to: "/coffeescript-mode-processing-master/release/" and open "CoffeeScriptMode.zip" file.
• Find your "sketchbook" folder and enter its "/modes" subfolder.
• Now you gotta unpack "CoffeeScriptMode.zip" into "sketchbook/modes/".

Yes, it's listed. It opens, but I don't see any buttons, and when I try to run a sketch (any sketch) it blows. That was on my Mac.

I'm on my PC now and it's listed, it opens, I can run the examples, but the code has no color coding. :S And when I try to run the simplest sketch written by me I only get this in my browser:

I'm going to try to install it manually now, thanks.

I can run the examples, but the code has no color coding.

Unfortunately, coding color highlight wasn't implemented yet. It's all mono black! :-&
Auto-format (CTRL+T) doesn't work either! :o3

If you successfully installed it in any system, you can simply copy 'n' paste that "/CoffeeScriptMode" subfolder to another "sketchbook/modes/"! B-)
Just remember to close all instances & re-open Processing after that though! L-)

Writing web apps is more difficult b/c it runs in a browser and we don't explicitly see "compile errors".
Rather, we gotta open a browser's console in order to inspect for any lurking exceptions! :-B
For Firefox family browsers, hit SHIFT + CTRL + J. And for Chromium's, hit SHIFT + CTRL + I. *-:)

CoffeeScript & Python languages use indentation instead of curly braces in order to denote scope blocks.
And "CoffeeScript Mode" is even more strict. We gotta choose how many spaces to use for it and stick to it!

This example below uses a 4-space indentation:
