First steps using Rascal


You can start using Rascal by following these steps:

  • Download and Install Rascal by carefully following the instructions at the Rascal Website.

Please respect the recommended versions of Java (JDK) and Eclipse (Eclipse for RCP Developers). In case of installation problems you can consult the trouble shooting page or StackOverflow.
  • Start Rascal. The Rascal system comes in two flavours: a command line version and a version integrated in Eclipse.

At the command line the Rascal system can be invoked by typing the command rascal. Next, the Rascal prompt rascal> appears and you can start typing commands (declarations, statements, expressions). To simplify interactive use, semicolons (;) that end commands may be omitted at the top level.
