INSTALLATION

Download the CoCo plug-in for Eclipse from here  and copy it to the directory <plugins> in the Eclipse home directory. You should do this before you start Eclipse. Eclipse loads the plugins from the plugins directory automatically at startup. 

START A JAVA PROJECT

This plug-in is only for the java version of Eclipse. Create a new java project. File->new project --> java project.

IMPORT REQUIRED FILES

You need to import these files to the project (only once, at the beginning) Coco.jar, Scanner.frame and Parser.frame. You will find these Files in the Directory Coco_library in the Coco Plugin directory. Please note that you need to use the Coco.jar included in this directory, as it is a special version that has been changed for this purpose. This is how the Project looks like, after you import all the required files.

CREATE A NEW FILE WITH EXTENSION .ATG

Using the right mouse click--> new file, you can create a new File. The file should have the exension .ATG. After doing this the ATGEditor is activated and you can write your attributed Grammar for your new compiler.
