Z Language Development Plan

This document outlines the development plan for the Z Language, focusing on language design, parsing, semantic analysis, code generation, and AI integration. All implementation is based on Python. The content is divided into contributions from team members, with tasks and timelines clearly defined.

Recommended Resources:

  • Compilers: Principles, Techniques, and Tools (Dragon Book) - Chapters 2, 3
  • Stanford CS143 Course
  • Paper: "Formal Language Theory and Language Design" by Noam Chomsky

Practice Suggestions:

  • Define a simple calculator grammar using EBNF
  • Identify different language types (regular, context-free, recursively enumerable)
  • Analyze the syntax rules of existing programming languages

1.2 Programming Language Design Principles

Why Learn: Helps establish core design principles and syntactic features for the Z Language.

Content:

  • Trade-offs in language design (simplicity vs. expressiveness)

  • Error handling and recovery strategies

Recommended Resources:

  • Programming Language Pragmatics by Michael Scott
  • Beautiful Code by Andy Oram & Greg Wilson

Practice Suggestions:

  • Analyze design decisions in Python, JavaScript, etc.
