A FiM++ interpreter written in Haskell, using Parsec as a parser.

This project uses stack, a tool for repeatable, cross-platform builds of haskell projects. You'll need to install stack to build the binaries or run the tests.

• Boolean, Character, Number, and String literals
• Assigning to/reading from variables
• Arithmatic Operators
• Comparison Operators
• Boolean Operators
• Branching Statements
• While and Do While, and For loops
• User Input
• Calling Methods
• Comments
• Increment/Decrement
• String concatenation
• Creating arrays
• Reading elements from arrays
• Writing to arrays
• Switches

• The error messages are... not good, especially for parsing/lexing

• Interfaces (what does this even mean in a language without objects?)
• Inheritence (Not much point without libraries)
• More than one class (no syntax for calling other classes or creating objects)
