Basic Programming

rascal-0.28.2

Rascal is a programming languages geared towards language processing:

• the backbone is procedural/functional programming with immutable data
• abstract and concrete grammars define parsers and hierarchical data-types
• relations and relational calculus provide database/logic query functionality

Here we briefly introduce the most relevant skills by example:

• source comments
• ./static typing
• Datatypes
• immutable values
• Enumerating
• ./Comprehensions
• pattern matching
• control structures
• case distinction
• Visiting
• ./Functions
• syntax definition and parsing
• Rewriting
• IDEConstruction
• code models
• equation solving

The reference manual spells out all syntax and semantics organized per language feature.
