Integrating CoffeeScript with Eclipse?

Question

Is there a way to integrate CoffeeScript and Eclipse, so that when I write CoffeeScript in one window the other will show the compiled code as Javascript?

I\'ll wait for

Answer 1

I wrote a plugin to automatically transpile CoffeeScript files (amongst others) automatically.

-> https://github.com/gossi/eclipse-transpiler-plugin

Basically, it does the same as Jon Stevens Shell script, but has a nice UI for the configuration.

I'm using coffees -w option for this. Open a terminal, cd to your project directory and then run coffee -w ./coffee -c ./js. Assuming that your coffee files are stored in a folder named coffee and you are compiling your files to a folder named js.

Keep the terminal open while your coding session. coffee will compile your script every time you resave the file.

I've done it with a builder and a small shell script in my project. Every time I save a .coffee file, it compiles all my scripts. Works great.

Right click on your project. Select properties near the bottom of the menu.

• Builders
• New...
• Location: ${workspace_loc:/ProjectName/coffee-compile.sh}
• Working Directory: ${workspace_loc:/ProjectName}
• Refresh: Specify the folder where your generated .js files live. This allows you to keep the .js file open as well and it'll auto update when things re-compile.
• Build Options: Specify the folder where your .coffee files live.

ProjectName/coffee-compile.sh:

#!/bin/bash

if [ ! -d ./target/coffee ]; then
    mkdir -p ./target/coffee
fi

echo "Compiling coffee script files..."
/usr/bin/coffee --output ./target/coffee --compile ./coffee

echo "Done..."

The builder definition is saved as part of your project. It is in the .settings folder. That way, other developers can check out your project as well and have everything already set up.

Update: For code formatting and coloring, I ended up installing the latest beta of Aptana into Eclipse.

Update2: I've stopped using Eclipse in favor of Intellij. The editors and built in support for compiling code are wonderful. I highly suggest you try it out.
