asteroid-lang 1.1.1

A pattern-matching oriented programming language.

Asteroid

Asteroid is a modern, multi-paradigm programming language supporting first-class patterns and pattern-matching oriented programming. More details can be found at the website asteroid-lang.org. Documentation on Asteroid can be found at asteroid-lang.readthedocs.io.

New in Release 1.1.1

• An experimental implementation of an interactive debugger that supports debugging pattern matching and in particular, pattern matching with first-class patterns.

• A Python API allowing the developer to call the Asteroid interpreter from within a Python program and also embed Python code in an Asteroid program.

• Eliminated the stride notation in list comprehensions and replaced it with the step notation.

• Lots of bug fixes.

New in Release 1.0.0

• Interpreter line-editing features similar to Python include interactive editing, history substitution and code completion on systems that support the GNU Readline library.

• New object-based modules for system modules. For example the functions within the io module are now accessed with the @ operator,

  load system io.
  io @println "Hello, World!".
  

• In the absence of explicit return statements the last expression evaluated within a function body provides an implicit return value, e.g.,

  function inc
     with i do
       i+1
     end
  

• Lots of bug fixes!
