Core Concepts

Oni has two application stacks that share Oni\Core:

• Oni\Web\App handles HTTP requests, static files, cached pages, controller dispatch, and view rendering.
• Oni\CLI\App handles command-line task routing and task lifecycle execution.
• Oni\Core\Loader registers application namespaces to filesystem paths via Loader::append($namespace, $path).
• Oni\Core\Basic provides the shared setAttr() / getAttr() configuration container.

Web Applications

A web app configures controller, view, static, and cache paths before calling run().

<?php
declare(strict_types=1);

require __DIR__ . '/../../vendor/autoload.php';

$root = __DIR__ . '/..';

$app = new Oni\Web\App();
$app->setAttr('controller/namespace', 'WebApp\Controller');
$app->setAttr('controller/path', "{$root}/controllers");
$app->setAttr('view/paths', ["{$root}/views"]);
$app->setAttr('static/paths', ["{$root}/static"]);
$app->setAttr('cache/path', "{$root}/caches");
$app->run();

Optional lifecycle hooks run before and after each request:

$app->setAttr('router/event/up',   function() { /* before dispatch */ });
$app->setAttr('router/event/down', function() { /* after dispatch  */ });

Controllers are named {Name}Controller and actions are named {action}Action.

Supported controller modes:

• Page: renders a view and can write GET responses to cache.
• Ajax: returns action data as JSON.
• Rest: maps HTTP methods to actions such as getAction() and postAction().

View

Oni\Web\View is a singleton injected by Web\App into Page controllers. Key methods:

• setData(array $data) — exposes variables to view templates.
• setIndexPath(string $path) — overrides the default index template path.
• setLayoutPath(string $path) — sets the layout template path.
• setContentPath(string $path) — sets the content partial path.
• render() — renders and returns the output as a string.

Model

Oni\Web\Model is a thin base class that extends Oni\Core\Basic, providing the setAttr() / getAttr() configuration container for application models.

CLI Applications

A CLI app configures the task namespace/path and an optional default task before calling run().

#!/usr/bin/env php
<?php
declare(strict_types=1);

require __DIR__ . '/../../vendor/autoload.php';

$root = __DIR__;

$app = new Oni\CLI\App();
$app->setAttr('task/namespace', 'CLIApp\Task');
$app->setAttr('task/path', "{$root}/tasks");
$app->setAttr('router/task/default', 'Help');
$app->run();

Tasks are named {Name}Task and implement run(array $params = []): void.

Task lifecycle:

up() -> run($params) -> down()

Run the CLI example:

php example/CLI/boot.php Help

IO

Oni\CLI\IO is a singleton that parses command input and provides output helpers.

Input parsing splits $argv into three buckets:

• arguments: positional values
• options: short flags such as -x or -x value
• configs: long options such as --key or --key=value

Access methods: getArguments(), getOptions(), getConfigs() and their has* counterparts.

Output helpers:

$io->write($text, $fgColor, $bgColor);   // write without newline
$io->writeln($text, $fgColor, $bgColor); // write with newline
$io->error($text);    // red
$io->warning($text);  // yellow
$io->notice($text);   // green
$io->info($text);     // bright black (dim)
$io->debug($text);    // white
$io->log($text);      // plain

Interactive methods:

• ask(string $text, ?callable $callback) — prompts the user, repeating until the callback returns true.
• menuSelector(string $text, array $options) — interactive arrow-key menu; returns the selected index (0-based) or null for an empty list.

ANSIEscapeCode

Oni\CLI\Helper\ANSIEscapeCode provides ANSI escape code constants and helpers for cursor movement, color output (color()), and cursor visibility (cursorShow() / cursorHide()).

Testing

Run the test suite:

vendor/bin/phpunit

The test suite covers core attributes, autoloading, CLI argument parsing, CLI task lifecycle, request accessors, view rendering, and HTML helper output.

Specifications

Current behavior is documented in:

• docs/specs/core.md
• docs/specs/cli.md
• docs/specs/web.md

These files describe the expected behavior that the automated tests should preserve.
