This adds an optional ext-terminal 1.x path for Solo's own terminal dimensions.

When the extension is available, the dashboard uses Io\Terminal\Terminal::getSize() for its initial size and resize handling. If the extension is missing, outside the supported 1.x range, or cannot resolve the size, Solo keeps using the existing Laravel Prompts / Symfony path.

I kept this intentionally narrow. The stty calls around GNU Screen are managing the child PTYs, so ext-terminal should not try to replace those. This only handles the terminal Solo itself is rendering into, where the native size API maps directly.

The resize path still updates COLUMNS and LINES for anything else in the process that relies on them. There's also a small PHPStan stub so the extension stays completely optional, plus a focused test for preferring the native dimensions path.

Small personal note: I've followed Solo since the original release and remember watching @aarondfrancis's video when it came out. I've wanted to find a useful place for php-terminal here for a while, so it was nice to finally find one that fits without forcing it.

Totally fine if an optional native extension isn't a direction you want Solo to take. I wanted to send the concrete, narrow version rather than open a broad integration proposal.

Summary by CodeRabbit

  • Bug Fixes
    • Dashboard dimensions now use the native terminal size when available, helping the display match the actual terminal. If native dimensions are unavailable, the dashboard continues to use the Laravel terminal size. After a resize, the dashboard updates its dimensions and corresponding environment settings using the available size.

Walkthrough

Dashboard now checks the native terminal extension for dimensions before using Laravel terminal dimensions. Resize handling applies the same lookup and restores COLUMNS and LINES from the selected dimensions. PHPStan loads a stub for the native terminal API, and a unit test checks native dimensions.

Changes

Terminal Dimensions

Layer / File(s) Summary
Native-first dimension lookup
stubs/ext-terminal.php, phpstan.neon.dist, src/Prompt/Dashboard.php, tests/Unit/DashboardTerminalTest.php
The stub declares the native terminal size API, and PHPStan loads it. Dashboard dimension lookup and resize handling prefer native dimensions when the extension and size are available. Otherwise, they use Laravel terminal dimensions. The test checks that getDimensions() returns native dimensions.

Merge Risk: 🔵 Low · up to a436a

Custom dashboards that override sizing may switch to different dimensions after a terminal resize. The change is otherwise mergeable with this bounded compatibility risk acknowledged or corrected.

Security Architecture Review

Security architecture risk: 🔵 Low · up to a436a

The change is limited to dashboard sizing and does not appear to expand access or privileges. One conditional failure path could leave terminal-dimension environment variables unset during resize; whether the native extension can trigger it is not established.

Retained concerns

  • Low · reliability · inferred: If the native size call throws during resize, the dashboard bypasses its fallback and leaves COLUMNS and LINES cleared until a later successful update. Runtime throw behavior is unverified.
Security review details

Security Blast Radius

  • inferred — The visible new exposure is limited to dashboard display geometry and its process-wide COLUMNS and LINES values; the examined paths do not establish a new attacker-controlled entrypoint or privilege.

Trust Boundaries and Controls

  • observed — Extension presence and version checks limit use of the native provider, while a false size result retains the Laravel fallback. These controls do not handle an exception from the native call.

Resilience and Maintainability Implications

  • inferred — An exception after resize clears COLUMNS and LINES would interrupt restoration and dimension propagation. This is a conditional failure-containment issue, not a verified native-extension failure.

Hardening Proposals

  • proposed — Consider isolating native lookup failures so resize can use the Laravel fallback, and ensuring cleared dimension variables are restored on exceptional exits.

A rabbit checks the terminal light,
Native rows and columns come in sight.
If they fail, Laravel fills the view,
Then resize sets the values true.

With tidy dimensions for the day.

instead of nativeDimensions() for resize sizing, while retaining the fallback
refresh. This ensures subclass overrides remain authoritative both during
initial sizing and after SIGWINCH.
