Delphi in all its glory: AI-assisted development: Tested on 150000 lines of code: An honest guide to AI for the Delphi programmers

By Gabriel Moraru and eng. Gabriel Moraru

It is a known fact that AI writes code faster than you. The same can be said about the number of bugs.

Your LinkedIn feed says programmers will be obsolete by next Thursday. Meanwhile, you're looking at real production code that real customers depend on, thinking: "Does any of this actually work for what I do?"

This book answers that question - honestly. No hype. No inflated promises. Just raw results from testing Claude Code on over 200,000 lines of production Delphi code. Failures included.

"Delphi in All Its Glory - Part 5" is the AI book that the big publishers won't write - because our community is too small for them. But not for us.

There are a gazillion books about AI out there. This is the only one written for Delphi developers.

What You'll Master

How LLMs actually work: tokens, context windows, hallucinations, and why Claude produces better Delphi code than the alternatives (while still making maddening mistakes).

Installation to production in one book: step-by-step setup on Windows, connecting Claude to your Delphi project, compiling from the command line, and interpreting errors through AI.

The day-to-day workflow: essential commands, code review techniques, and practical patterns for making AI useful rather than impressive.

Real-world stress tests - not toy calculators: Claude was tested on actual production projects with documented results - what it did well, what it got wrong, how much it cost, and how much time it actually saved. No cherry-picked examples.

The single most important thing you can do: creating skill documents (CLAUDE.md) that teach Claude your coding conventions. This alone transforms AI output from "generic code that compiles" to "code that looks like mine."

Advanced techniques: MCP servers, hooks, sub-agents, IDE integration options, and the tools that multiply AI's effectiveness.

Under the hood: how Claude Code actually works, best practices, common workflows, cost management, data privacy, and security. Know exactly where your code goes and who sees it.

The verdict: an honest, numbers-backed assessment of whether AI-assisted Delphi development is worth your time and money right now.

Who Benefits Most?

Everyone will see some benefit. But if you maintain legacy code - especially pre-Unicode Delphi - AI is a direct ticket to heaven. Here's a secret: AI is much better at fixing broken code than at writing new clean code. If you're on Delphi 2009 or older, drop the hammer. You don't need it anymore.

Why Claude Code?

It works as an agent - reading files, understanding project structure, running your compiler, and iterating on errors. This is fundamentally different from autocomplete-style tools. And the concepts (tokens, prompting, context management) transfer to any AI tool you'll use in the future.

The Series

Part of "Delphi in All Its Glory" - five books, 2,000+ pages, seven years in the making.
Part 1 lays the foundation.
Part 2 covers the compiler, debugging, memory management, and exceptions.
Part 3 tackles libraries and packages - the architectural backbone that makes large-scale Delphi development possible.
Part 4 goes cross-platform with FMX.
Part 5 brings in AI-assisted development with Claude Code.
