MyPL - Programming Language Interpreter

Description

This programming language is a work in progress. I finished a basic set of operations, constructs, and methods that can be performed as per the requirements of a PL course. Beyond this, I have started extending this language by adding an additional construct: dictionaries (Python) or undordered maps (C++).

Installation

To "install" this language one must run a set of commands:

• CMake to build tools that will process dependencies

cmake .

• Make to process dependencies and build the language

make

Usage

To run:

./mypl [flag] [file]

Available flags:
--lex: lexical analysis
--parse: parsing, AST generation
--print: pretty printer
--check: semantic checking
--ir: machine instruction generation
--help: usage message

Features:

• lexical analysis
• simple parsing
• AST generation
• pretty printer
• semantic checking
• machine instruction generation with VM
• running programs written in 'MyPL'

Language Benefits:

• types
  • user-defined struct [name] { [fields]* }
  • 1D arrays array [type] [id] = new [type][ [size] ]
  • primitive [type] [id] = [val]
• methods
  • length (string, arrays) length([id])
  • get/set fields [id][val]
  • get/set array index [id][val]
  • get char in string get(val)
  • terminal I/O (print, input) print([type]), input()
• extended use
  • dictionary (unordered map) type dict [type1] [type2] [id] = new dict{type1, type2}
  • methods: keys, values keys([id]), values([id])

An example of this language's use has been published to YouTube.
