Awesome Lists containing this project

• awesome-programming-languages - RascalMpl - Rascal Metaprogramming Language. Rascal is a programming language; such that meta programs can be created by, understood by, and debugged by programmers. Rascal primitives include immutable data, context-free grammars and algebraic data-types, relations, relational calculus operators, advanced patterns matching, generic type-safe traversal, comprehensions, concrete syntax for objects, lexically scoped backtracking, and string templates for code generation. It has libraries for integrating language front-ends, for reusing analysis algorithms, for getting typed meta-data out of version management systems, for interactive visualization, etc. (Uncategorized / Uncategorized)

# Rascal - Metaprogramming Language

[![Build and Deploy](https://github.com/usethesource/rascal/actions/workflows/build.yaml/badge.svg)](https://github.com/usethesource/rascal/actions/workflows/build.yaml)

This is the core implementation of the Rascal meta-programming language. It contains the interpreter, the parser generator, the parser run-time,

the (documented) standard library, the type checker, the compiler, and the documentation compiler ("tutor").
