Projekt Barium - A Basic Compiler for Barium Programming Language

This is the compiler i built for my programming lanugage barium, a fun little project to understand compilers.

Tech Stack : Flex, Bison, LLVM

The Compiler Recipe

Lexical Analyzer (Lex) -> Semantic Parsing (Bison) -> Assembly (LLVM) -> Executable

Task List

• Add Data Types (decimal, fraction)
• Operators, Symbols, Reserved Keywords
• Add Looping Statements - ongoing (parse done)
• Add Control Statements - ongoing (parse done)
• Add Output Statements - uses vprintf
• Add Input Statements
• Add Arrays Support - ongoing (parse done)
• Create a CI/CD Pipeline
• Output executables instead of obj files (partial support)
• locations (YYLTYPE, and @$)

Far-fetched task list

• Make it a Library
• Add Boost Math Support
• Containerize the Compiler using Docker

Dependencies

• LLVM 9.0.1
• Bison 3.5.2
• Flex 2.6.4

Known Issues

• Spacing is required between operators to remove ambiguity
