# delphi-dev

A Claude Code plugin for Delphi work. It applies coding standards, reviews projects, creates tests and runs guided end-to-end checks for desktop apps.

## What it does

delphi-dev switches on when Claude Code encounters `.pas`, `.dpr`, `.dfm`, `.dpk` or `.dproj` files, or references to Object Pascal, FireMonkey, VCL, FireDAC or RAD Studio. It supplies Delphi Style Guide, Clean Code and SOLID context without a separate prompt.

The plugin includes commands for technical audits, code review, new project scaffolding, `SPEC.md` generation and DUnitX test suites. `/e2e` builds a project, opens its `.exe`, drives the real screens and reports a verdict for each scenario while checking the application log. Before actions that write data, it shows the planned cases and waits for approval.

The `/e2e` build flow requires Windows and RAD Studio; FireMonkey is validated, while VCL is treated as a fallback and Android is outside its scope. Installation requires Node.js 18+, the Claude Code CLI and git. Automation hooks are disabled, so automatic per-prompt knowledge injection and session capture are currently off.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install delphi-dev@claude-community
```

## When to use it
- audit a Delphi codebase
- spot violations in existing source
- scaffold a layered Delphi project
- generate a DUnitX test suite
- exercise desktop app scenarios end to end

## Example prompts
- Run `/delphi-dev:audit` on this Delphi project and produce a scored audit with a modernization roadmap.
- Use `/delphi-dev:review` to inspect this unit, flag standards violations and show corrected code.
- Run `/delphi-dev:e2e` for login cases with a blank password, a wrong password and a valid password.

## What is it

**delphi-dev** activates automatically whenever Claude Code detects Delphi-related content — `.pas`, `.dpr`, `.dfm`, `.dpk`, `.dproj` files, or any mention of Object Pascal, FireMonkey, VCL, FireDAC, or RAD Studio. Once active, Claude applies the full Delphi Style Guide, Clean Code principles, and SOLID patterns without being asked.

## Features

| Command | Description |
|---|---|
| **Auto Delphi Mode** | Opening any `.pas`, `.dpr` or `.dfm` file activates the full coding standards context automatically |
| **`/audit`** | Generates a complete professional technical audit with per-dimension scoring and a prioritized modernization roadmap |
| **`/review`** | Quick code review — detects violations and provides corrected examples |
| **`/write`** | Writes new code with all standards applied from the start |
| **`/new-project`** | Scaffolds a new project with standardized layered folder structure |
| **`/spec`** | Analyzes the current project source code and auto-generates a complete `SPEC.md` |
| **`/tdd`** | Generates a complete DUnitX unit test suite for the project |
| **`/e2e`** | Runs end-to-end scenarios against a running Delphi desktop app — builds it, opens the `.exe`, drives the screens and reports a verdict per scenario |
| **`/contribute-kb`** | Packages local learnings captured by the hooks and opens a PR to the community knowledge base *(needs hooks, currently disabled — see Installation)* |
| **`/dashboard`** | Displays GitHub repository metrics — stars, forks, issues, PRs, commits, releases, contributors |
| **`/about`** | Displays plugin info, version, and available commands |

## End-to-end testing with `/e2e` <sub>new in 3.2.0</sub>

Think of it as **Playwright for Delphi desktop apps**. You describe test scenarios in plain
language; the plugin builds the project, opens the `.exe`, drives the real screens, and returns
a **verdict per scenario** — correlated with your app's log.

```
/e2e login: blank password, wrong password, correct password
```

Without arguments, `/e2e` derives an "opens without error" scenario for each screen of the
main menu.

### Four verdicts, not two

The distinction is what separates a useful report from noise:

| Verdict | Meaning |
|---|---|
| ✅ PASS | Ran and matched the expectation |
| ❌ FAIL | Ran and diverged — **the app is wrong** |
| ⛔ BLOCKED | Couldn't run — **I don't know whether the app is wrong** |
| ⏭️ SKIPPED | Writes data and wasn't authorized at the gate |

A report that blames a bug where there was only state contamination is worse than no report.
So when a scenario can't be returned to its starting point, it comes back **⛔ BLOCKED, never
❌ FAIL**.

### It never steals focus

Clicks go through `PostMessage`, text through `WM_CHAR`, screenshots through `PrintWindow` —
so the plugin **never grabs your keyboard and never moves your cursor**. Screenshots work even
with the window fully covered, and `WM_CHAR` is immune to the dead-key problem of ABNT
keyboards that breaks `SendKeys`.

By default the app runs in the foreground so you can watch. Pass `--background` and it runs
behind your other windows without interrupting you.

### It stops and asks before touching your data

Before the first click, `/e2e` presents the scenarios it intends to run, **which ones write
data and what they write**, and waits. It never writes on its own initiative — it explores,
captures, and leaves through Cancel/Back.

### It reads your app's log

Delivery is not effect: a message can reach the window and still do nothing if the control
isn't in the expected state. That's why `/e2e` reads your log in parallel — it's the difference
between ⛔ BLOCKED and ❌ FAIL. If your app has no log, the plugin **offers** (never imposes)
either a minimal logging unit or a headless `--selftest` mode, and generates it following the
plugin's own coding standards.
