This is the official MiniCompiler web page. MiniCompiler is used at the Department of Information Technology, Klagenfurt University, Austria for the compiler construction course. It translates the PL0 language to MIPS assembler code and is hand-written in Java. The compiler is separated into five stages, each stage adding functionality to the compiler.

MiniCompiler Visualization

Visualizes the compilation process of the MiniCompiler. The main features are

• Visualization of symbol table
• Visualization of parse tree
• Live MIPS code generation

The Visualization Applet can be started online here!!

Download the Stages

MiniCompiler - Stage1: Lexer
MiniCompiler - Stage2: Parser
MiniCompiler - Stage3: Symbol Table
MiniCompiler - Stage4: TypeChecking
MiniCompiler - Stage5: Code Generator

Each stage can be (optionally) added to an Eclipse workspace. Furthermore ANT build files exist for easy compilation.
