PSCAL Project Overview

At the time of this writing PSCAL is possibly the world's largest and most complex vibe coding project. It was created primarily with Gemini 2.5 Pro's Coding partner and more recently, Open AI's Codex utilizing GPT-5. Other AI tools were utilized in early development, which dates back to March of 2025. This release comes just nine days after the initial release. See the "What's Changed" section below for details on how much has changed in that time. One of many additions was the creation and incorporation of a new front end reminiscent of C.

PSCAL is an extensible virtual machine and compiler suite implemented in C. The project ships with multiple frontends that all target the shared, stack-based virtual machine:

• Pascal compiler: A frontend for a Pascal-like language with a hand-written lexer and parser.
• Clike compiler: A compact, C-style language frontend that includes its own preprocessor and a REPL for interactive sessions.
• Tiny compiler: An educational frontend written in Python.

All frontends generate a compact bytecode stream that is executed by the VM. This virtual machine provides a rich set of built-in routines and offers optional integrations with SDL2 for graphics and audio, and libcurl for networking. The system is designed to be easily extensible, allowing for the addition of new built-in functions.

---

Core Architecture

The project follows a classic compiler and virtual machine design:

• Frontends: Each frontend is responsible for parsing its respective language (Pascal-like or C-like) and constructing an Abstract Syntax Tree (AST).
• Compiler: A compiler processes the AST, performs semantic analysis (for the C-like language), and generates bytecode. The C-like frontend also includes an optimization pass to improve the generated code.
• Virtual Machine (VM): A stack-based VM executes the bytecode, providing a portable runtime environment.
• Symbol Table: A hash table-based symbol table manages variables, functions, and types during compilation.

---

Key Features and Capabilities

• Dual Language Support: The ability to compile both Pascal-like and C-like code to the same bytecode is a major feature.
• Graphics and Audio: Through SDL bindings, the language supports creating graphical applications with audio capabilities, including window creation, shape and text rendering, and sound playback.
• Networking: A networking API using libcurl allows for making HTTP requests and handling responses.
• Rich Built-in Library: A comprehensive set of built-in functions is provided for:
  • File I/O (readln, writeln, fileexists).
  • Math (sin, cos, sqrt, factorial, fibonacci, chudnovsky).
  • String manipulation (copy, pos, length).
  • System interaction (getpid, dos_exec).
• Bytecode Caching: To speed up subsequent runs, the compiler can cache bytecode for source files that have not been modified.

---

How It Works

1. Parsing: Source code is processed by the appropriate lexer and parser to build an Abstract Syntax Tree (AST).
2. Semantic Analysis: For the C-like language, a semantic analysis pass checks the AST for correctness, such as type errors.
3. Compilation: The compiler traverses the AST to generate a portable, low-level bytecode representation of the program.
4. Execution: The virtual machine executes the bytecode. As a stack-based machine, it uses a stack for data manipulation and calculations while processing the bytecode instructions.

---

Requirements

• C compiler with C11 support
• CMake 3.24 or newer
• libcurl
• Optional: SDL2, SDL2_image, SDL2_mixer and SDL2_ttf when building with -DSDL=ON

---

Building

mkdir build && cd build
cmake ..          # add -DSDL=ON to enable SDL support
make

To explicitly disable SDL support:

cmake -DSDL=OFF ..

---

Testing

After compiling, run the regression suite:

cd Tests; ./run_all_tests

Directory Layout

• src/: Core compiler(s) and virtual machine sources
  • backend_ast: Contains the backend of the compiler, focusing on the Abstract Syntax Tree (AST). It includes the code for built-in functions and interface.s
  • clike: The complete frontend for the C-like language.
  • compiler: Contains core components of the compiler that are shared across the different language frontends such as bytecode definition and the portion that translates the AST into bytecode.
  • core: Houses fundamental utilities and data structures used throughout the project. This includes implementations for lists, bytecode caching, and common type definitions.
  • ext_builtins: The source code for additional, "external" built-in functions. This modular design allows for new features to be added to the language easily.
  • pascal: The Pascal-like language frontend, containing its lexer, parser, and AST implementation.
  • symbol: The implementation of the symbol table, which is a critical component for the compiler to manage identifiers such as variables and functions.
  • vm: The source code for the stack-based virtual machine that executes the bytecode produced by the front ends.
• lib/pascal/: Standard library units written in Pscal
• lib/clike/: Standard modules written in clike
• lib/sounds/: Audio assets shared by front ends
• Examples/: Sample programs for each front end
• Docs/: Project and language documentation
• tools/: Additional front ends and utilities (e.g. tools/tiny)
