The Bridge Pattern +To solve the conflict between "Phred Integration" and "Standalone Portability," Tasker will advocate for a split between **Logic** and **Presentation**: +- **Core Logic**: Remains in the library's service layer (e.g., `Pairity\Migrations\Migrator`). +- **Command Wrapper**: A thin class that implements a simple, common interface. +- **Bridges**: + - **PhredBridge**: The primary runner used by `Tasker`. + - **Bridges Package**: A dedicated, lightweight `getphred/tasker-bridges` package will provide `PhredBridge`, `SymfonyBridge`, and `LaminasBridge`. This avoids copy-pasting code across libraries while keeping the core library decoupled from the main `Tasker` runner. + +### 2. "Internal Standard" Interfaces (Proposed Implementation) +Since there is no `psr/cli`, Tasker will define a minimal, framework-agnostic set of interfaces. To ensure true decoupling, these interfaces should either: +- **Reside in a lightweight Contracts package** (e.g., `getphred/console-contracts`) that both the library and `Tasker` depend on. +- **Be duplicated/re-implemented** as a simple contract within the library if a shared package is not desired. + +#### Proposed Command API (Hybrid Approach): + +**CommandInterface** (In `ConsoleContracts`) +```php +namespace GetPhred\ConsoleContracts; + +interface CommandInterface +{ + public function getName(): string; + public function getDescription(): string; + + /** + * @return array Name => Description + */ + public function getArguments(): array; + + /** + * @return array Name => Description + */ + public function getOptions(): array; + + public function execute(InputInterface $input, OutputInterface $output): int; +} +``` + +**Base Command Implementation** (In `Tasker` or a Trait) +```php +namespace Phred\Tasker; + +use GetPhred\ConsoleContracts\CommandInterface; + +abstract class Command implements CommandInterface +{ + protected string $name = ''; + protected string $description = ''; + protected array $arguments = []; + protected array $options = []; + + public function getName(): string { return $this->name; } + public function getDescription(): string { return $this->description; } + public function getArguments(): array { return $this->arguments; } + public function getOptions(): array { return $this->options; } +} +``` + +**User Implementation Example** +```php +class MigrateCommand extends Command +{ + protected string $name = 'db:migrate'; + protected string $description = 'Run database migrations'; + + public function execute(InputInterface $input, OutputInterface $output): int + { + // Logic here + return ExitCode::OK; + } +} +``` + +**InputInterface** +```php +namespace GetPhred\ConsoleContracts; + +interface InputInterface +{ + public function getArgument(string $name, mixed $default = null): mixed; + public function getOption(string $name, mixed $default = null): mixed; + public function hasOption(string $name): bool; +} +``` + +**OutputInterface** +```php +namespace GetPhred\ConsoleContracts; + +interface OutputInterface +{ + public function write(string $message): void; + public function writeln(string $message): void; + public function success(string $message): void; + public function error(string $message): void; + public function warning(string $message): void; +} +``` + +### 3. Command Discovery & Injection (Proposed Implementation) +Tasker is designed to work with any PSR-11 container. + +#### Discovery Ideas: +1. **Explicit Registration (DI Container)**: User adds command classes to the DI container. **This takes precedence.** +2. **Auto-Discovery (Composer)**: Tasker scans for a `phred-tasker.json` file in the root of installed packages or a `extra.phred-tasker` key in `composer.json`. + ```json + "extra": { + "phred-tasker": { + "commands": [ + "Pairity\\Console\\Commands\\MigrateCommand", + "Pairity\\Console\\Commands\\SeedCommand" + ] + } + } + ``` + +#### Injection & Translation: +Commands should use **Constructor Injection** for their dependencies. Tasker will use the PSR-11 container to instantiate them. + +Translation is the **responsibility of the Command implementation**. Commands should inject a translator service (e.g., from `Langer`) via the container and handle translation before calling output methods. This keeps the `OutputInterface` lean and framework-agnostic. + +```php +namespace Pairity\Console\Commands; + +use GetPhred\ConsoleContracts\CommandInterface; +use Pairity\ORM\Manager; + +class MigrateCommand implements CommandInterface +{ + public function __construct( + private readonly Manager $manager + ) {} + + // ... getName, execute, etc. +} +``` +Proposed Flow: +1. Identify `MigrateCommand` as the handler. +2. Request `MigrateCommand` from the PSR-11 container. +3. The container injects the `Manager` (already configured in the app). +4. Tasker calls `execute()`. + +### 4. Exit Code Standards +Tasker follows the `sysexits.h` standard for exit codes to ensure interoperability with system tools and shell scripts. To simplify development, Tasker provides an `ExitCode` utility with semantic constants. + +| Constant | Code | Meaning | +|:---|:---:|:---| +| `ExitCode::OK` | **0** | Successful termination. | +| `ExitCode::USAGE` | **64** | Command line usage error (invalid arguments/options). | +| `ExitCode::DATAERR` | **65** | Data format error. | +| `ExitCode::NOINPUT` | **66** | Cannot open input (file not found/unreadable). | +| `ExitCode::UNAVAILABLE` | **69** | Service unavailable. | +| `ExitCode::SOFTWARE` | **70** | Internal software error (exceptions/logic failures). | +| `ExitCode::IOERR` | **74** | Input/output error. | +| `ExitCode::PERM` | **77** | Permission denied. | +| `ExitCode::CONFIG` | **78** | Configuration error. | + +### 5. Interactivity & Portability +To maintain extreme portability, the `OutputInterface` will remain a simple pipe for strings. Interactive features (e.g., asking questions, confirmation prompts) will NOT be part of the core `ConsoleContracts\OutputInterface`. + +Instead, Tasker will define an optional `InteractionInterface` (or similar helper) that can be injected into Commands via the DI container. This allows: +- **Standalone Library Portability**: Commands only need to know how to write output. If they need user input, they depend on an interface that can be satisfied by any runner (Tasker, Symfony, etc.). +- **Bridge Support**: `TaskerBridges` will provide implementations of this interface for `symfony/console` (wrapping `QuestionHelper`) and Tasker (using `STDIN`/`STDOUT`). +- **Clean Transitions**: If a developer switches from Tasker to native Symfony Console, they only need to swap the DI implementation for the interaction helper; the command logic remains untouched. + +### 6. Metadata Configuration (Hybrid Approach) +To balance strict interface enforcement with modern Developer Experience (DX), Tasker adopts a hybrid approach for command metadata (name, description, etc.): +- **Interface-Driven**: `CommandInterface` remains method-based (`getName()`, etc.) to ensure that any runner can reliably retrieve metadata. +- **Property-Based DX**: A base `Command` class (or trait) provides default implementations of these methods that read from protected class properties. This mimics the concise configuration style of Symfony Console while maintaining the architectural purity of interfaces. +- **Lazy Loading Readiness**: This structure allows the runner to potentially use Reflection or static analysis to read metadata without full instantiation if needed in the future (similar to Symfony's static properties or attributes). + +### Phase 1: The Standard & Bridges +- **Contracts**: Define the core interfaces in a very lightweight package (e.g., `getphred/console-contracts`). +- **Bridges Package**: Create `getphred/tasker-bridges` to house `PhredBridge`, `SymfonyBridge`, and `LaminasBridge`. +- Ensure all components use PHP 8.2+ strict typing. + +### Phase 2: Migration of Existing Libraries +- **Pairity**: Refactor `Pairity\Console\Application` logic into Tasker-compatible commands. +- **Atlas**: Formalize `Atlas\Commands\ListRoutesCommand` into the Tasker standard. +- **Scape**: Identify any CLI needs (e.g., cache clearing) and implement them. + +### Phase 3: The Framework Glue +- The `Framework` package will include Tasker by default and pre-configure it to aggregate commands from all installed Phred libraries. + +## Implementation Roadmap & Checklist + +To ensure Tasker is an efficient, user-friendly, and enterprise-ready package, the following checklist must be completed. + +### 1. Product Definition & Scope +- [ ] **Define MVP**: Confirm if the MVP is "Run registered commands with DI, explicit discovery via Composer extra, standard input/output, and `--help`/`list` UX." +- [ ] **Finalize SPECS.md**: + - [ ] Document v1 contracts (Input/Output/Command). + - [ ] Define the JSON schema for `composer.json` discovery. + - [ ] Define runner behavior (exit codes, verbosity flags, non-interactive mode). +- [ ] **Populate MILESTONES.md**: Map deliverables to specific, verifiable milestones. + +### 2.
