📝 Walkthrough

Walkthrough

This PR adds the stellarwp/foundation-view split package. It introduces view-rendering contracts, a PhpView implementation, provider bindings, package metadata, tests, fixtures, and documentation. It also wires the package into the monorepo and docs navigation.

Changes

Foundation View package

Layer / File(s) Summary
Package setup
AGENTS.md, README.md, composer.json, src/View/composer.json, src/View/README.md, src/View/.gitattributes, src/View/.gitignore, src/View/.github/workflows/close-pull-request.yml
Added stellarwp/foundation-view to the monorepo package lists and Composer replacement map. Added PSR-4 autoloading for StellarWP\Foundation\View\. Added the split-package manifest, package README, archive rules, local ignore rules, and the PR-closing workflow for the split repository.
Contracts and provider
AGENTS.md, src/View/Contracts/*, src/View/Exceptions/ViewNotFoundException.php, src/View/ViewProvider.php
Added the View and DirectoryAwareView public contracts, the ViewNotFoundException, and ViewProvider. The provider validates view.directory, constructs PhpView, and binds PhpView, View, and DirectoryAwareView as shared services.
PHP renderer
src/View/PhpView.php
Added PhpView as a readonly, directory-aware renderer. It validates configured directories and view names, resolves readable .php files inside the trusted directory, supports immutable withDirectory(), renders with extracted data, and restores caller-owned output buffers while rejecting unsafe buffer changes.
Tests and fixtures
tests/Support/Fixtures/View/*, tests/Unit/View/*, tests/_data/View/...
Added fixtures and unit tests for the renderer contracts, provider registration, runtime directory changes, escaping, nested views, protected internal variables, invalid directories and names, missing files, output-buffer edge cases, thrown exceptions, and symlink traversal outside the configured directory.
Documentation
src/Docs/astro.config.mjs, src/Docs/src/content/docs/components/view.mdx, src/Docs/src/content/docs/start/what-is-foundation.md
Added the View component guide and linked it from the Components sidebar. Updated the Foundation overview to include view conventions.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 00d05

The new view package can leave output buffering active when a template creates a non-removable buffer, potentially corrupting subsequent response output; this should be fixed or explicitly accepted before merging. The documentation example and pull-request workflow also need bounded follow-up.

I'm not sure we need to be so strict. I would prefer to throw an exception in configurable debug or develop mode (WP_DEBUG is WordPress's way). In production, I would render an empty string if something goes wrong. We can pass a PSR logger if we want to log that.

Not sure I agree, for our internal projects I want to fail hard and fail fast. The programming where things sort of silently fallback can mask seriously hard to find bugs in my experience, where if this happened it would point the developer where to look, but let me think about it a bit.

Nested sounds like nested templates. But it's just second-level directory 😄

Remove the unnecessary Container alias.

No visible class-name collision requires C. Import Container directly and use Container $container in both factory closures.

Proposed change
-use lucatume\DI52\Container as C;
+use lucatume\DI52\Container;
 ...
-		$this->container->singleton(View::class, static fn (C $c): PhpView => $c->get(PhpView::class));
-		$this->container->singleton(DirectoryAwareView::class, static fn (C $c): PhpView => $c->get(PhpView::class));
+		$this->container->singleton(View::class, static fn (Container $container): PhpView => $container->get(PhpView::class));
+		$this->container->singleton(DirectoryAwareView::class, static fn (Container $container): PhpView => $container->get(PhpView::class));

As per coding guidelines, “Avoid use ... as ... import aliases unless they resolve a real class-name collision or ambiguity.”

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Handle reopened pull requests.

When a contributor reopens a closed pull request, types: [opened] does not run. Add the reopened event so the read-only repository closes and redirects reopened pull requests as well.
