Terminal Laravel Package

Getting Started

Start by installing the package via Composer (composer require php-school/terminal). Its primary use case is detecting terminal environment properties to conditionally format output. The first thing you’ll reach for is Terminal::isatty() to verify whether output goes to an actual terminal (vs. a pipe or file), and Terminal::getSize() to get width/height for responsive layout. Look at php-school/terminal’s TerminalInterface—it defines a clean, minimal API with no heavy dependencies. Since the last release was in 2019, assume it’s stable but lightly maintained; ideal for foundational terminal introspection where full frameworks (like Symfony Console) would be overkill.

Implementation Patterns

• Conditional Styling: Use isatty() to enable colors only when supported (if ($terminal->isatty(STDOUT)) { $output->write('<fg=yellow>…</>'); }), avoiding ANSI codes breaking log files or CI outputs.
• Responsive Layouts: Pair getSize() with width()/height() to adjust table columns or progress bar width ($width = $terminal->getSize()->getWidth(); $bar->setMaxWidth($width - 10)).
• Fallback UIs: Detect capabilities via getCapabilities()—e.g., disable interactive prompts if supportsInteractive() returns false (useful for CI, cron jobs, or non-TTY CI runners).
• Integration: Often used in smaller CLIs or internal tools where extracting console abstraction isn’t justified—e.g., in custom scaffolding tools or monorepo utilities where you want php mytool.php | grep foo to work without garbled output.

Gotchas and Tips

• Windows Compatibility: Works on Windows 10+ (with ANSI support enabled), but older systems (pre– anniversary update) may fall back to limited mode; always test in actual CI environments (e.g., GitHub Actions windows-latest).
• Piped Input Detection: isatty(STDIN) is critical for tools that behave differently in pipelines (php mytool.php | grep bar). Never assume TTY → always check stdin/output separately.
• No Dependency Injection Trap: Because it’s stateful (detects environment once), avoid injecting terminal instance in long-running processes (e.g., Swoole, ReactPHP apps)—re-instantiate on context change or mock in tests.
• Mocking for Tests: In unit tests, use Terminal::mock() or a test-double that returns fixed dimensions/capabilities—don’t rely on actual terminal environment.
• Staleness Risk: Since the library hasn’t been updated since 2019, prefer it only for detection logic—not terminal control (e.g., cursor manipulation). For complex交互 (menus, progress bars), layer on top with php-school/terminal as the detection layer, but let a more active library (like symfony/console) handle rendering.
