Running Rascal in Eclipse

rascal-0.40.17

After the installation procedure running Rascal in Eclipse is a matter of starting the Rascal Shell:

  1. with the command button
  2. using the the pull-down menu

Starting Rascal Shell with the command button.​

  • If no project was (ever) selected the button starts a Rascal Shell with only the standard library on its path
  • Otherwise, the last selected project in any navigator, or opened file in the edit space, selects the project that is used to configure the search paths.
  • Use the create new project instructions, or the New project Wizard in Eclipse to obtain a Rascal project setup.

The Rascal logo appears twice in the button bar:

  • the left one is to start the Rascal Shell
  • the right one is to select the Rascal Eclipse "perspective" with additional features like the "Rascal Navigator"

Starting Rascal Shell from the menu​

From the menu the behavior is exactly the same as from the button bar:

Programmatic access to Eclipse features​

  • Use IDEServices to communicate with Eclipse, to register problems, to open files and browsers, etc.
  • Use util::IDE for programming Eclipse plugins for languages designed using Rascal.
  • The project://<projectName> location scheme provides access to the root of each registered folder in the VScode workspace.
  • Use getProjectPathConfig for Java and Rascal project configuration extracted from Maven and Eclipse configuration (classpaths, sourcepaths, library dependencies).

The util::IDE module is waiting to be documented
