Crafting Interpreters

Read on craftinginterpreters.com

Summary

Crafting Interpreters is a hands‑on guide that walks you through building two complete Lox interpreters from scratch, writing every line of code by hand. It focuses on practical implementation, language design insights, and challenges to deepen your understanding of compilers and data structures.

  • Building an interpreter forces you to master recursion, dynamic arrays, trees, graphs, and hash tables used in everyday code.
  • The book provides every line of source for two full Lox interpreters, written by hand without lexer/parser generators.
  • Each chapter adds a language feature, includes challenges, and discusses design trade‑offs alongside implementation details.
  • The style prioritises practical, runnable code and hands‑on exercises over heavy theory, helping readers internalize concepts quickly.

Software engineers who want to understand how languages work or need to build DSLs will benefit from the concrete, end‑to‑end examples.

  1. Article: Your Next DSL Author Is a Language Model

    Typed Domain Grounding (TDG) embeds a DSL inside a mainstream language the LLM already knows (e.g., Kotlin) and uses the host compiler as an oracle. The author describes five building blocks—embedding, choosing a host language with high training‑data frequency, compiler‑driven type safety, a generate‑compile‑repair loop, and an on‑demand teaching tool—and shows measured results from kUML, a Kotli…

  2. How I Wrote a Forth (Without Knowing How)

    The author details building MoonForth, a Forth interpreter written in C that leverages Lua's C API for stack manipulation and word storage. The process was surprisingly straightforward, reinforcing the idea that Forth "writes itself" by iteratively filling missing functionality.

  3. Blog: How to Build a DevOps Agent

    This blog walks through the open‑source DevOps Agent Kit, which lets Claude Code or Cursor act as a DevOps assistant by connecting to CloudBees Unify, Jira, and Slack via MCP servers and to GitHub via the CLI. It provides a repeatable setup (Docker, Node, env file) and seven slash commands for pipeline overview, triage, security, release readiness, flag management, CI health scoring, and Jira tic…

  4. One style guide for everything Claude Code writes

    A detailed walkthrough of forking the nbj‑write‑clearly Claude Code skill to enforce the Google Developer Documentation style guide across all developer‑facing prose (docs, comments, commit messages, review feedback). The fork expands the trigger set, vendors the 70‑page guide offline via a Bun sync script, and adds a layered approach (global CLAUDE.md rules, on‑demand skill, per‑agent preloaded…

  5. Build, deploy, and operate with coding agents on Render

    Render adds OAuth‑based MCP access, expands its “skills” library to 20+ actions, and upgrades the CLI to manage full service lifecycles, enabling coding agents (Cursor, Claude, Codex, ChatGPT) to trigger deploys, adjust plans, and spin up disposable PR environments via structured JSON/YAML commands.
