warpui_core: TUI presenter, runtime (crossterm), and end-to-end integration by zachbai · Pull Request #12601 · warpdotdev/warp

Description

Final PR in the stack: wires the TUI elements (#12634) into a working backend. Behind the tui feature; default builds are unaffected.

TUI presenter (presenter/tui.rs): an immediate-mode render pass that lays out the TuiElement tree and feeds the shared view hierarchy via report_view_embeddings (the map introduced in warpui_core: backend-neutral view hierarchy for a shared responder chain #12413) — so focus and action dispatch work identically to GUI.
Runtime (runtime/*): a crossterm renderer plus terminal-event → warpui event conversion, driving redraws through the same window_invalidations the GUI uses.
crossterm added as an optional dependency, gated on tui.
End-to-end integration test (tests/tui_integration.rs) exercising the full stack.

Design note: TUI rendering is intentionally immediate-mode and does not adopt the GUI's two-phase scene cache — the two render paths stay divergent by design.

Reviewing: start at presenter/tui.rs (render pass + embedding wiring), then runtime/ (crossterm renderer + event conversion). Everything is tui-gated.

Stack

#12413 → #12633 → #12634 → #12601 (this)

Testing

cargo check -p warpui_core -p warp -p warpui clean in both default and --features tui.
cargo nextest -p warpui_core --features tui: 365/7; integration test passes.

…ain (#12413) ## Description First PR in a stack that adds an optional TUI backend to `warpui`. This PR is **only** the backend-neutral groundwork — no TUI code, no behavioral change. Today the view responder chain (focus/blur, action dispatch, ancestor walks) is derived from the **GUI presenter's** layout-time parent map. This PR moves that ownership into `AppContext` so any backend can drive it: - New `AppContext.view_parents` — a per-window child→parent view map. - Fed from two sources: creation-time structural parentage (`record_view_parent`) and the active backend's render pass (`report_view_embeddings`). - Walked by `view_ancestors` / `view_parent_map`; all responder-chain / focus / dispatch sites now read this map instead of `presenter.ancestors()`. - The GUI presenter is updated to feed `report_view_embeddings`, so GUI behavior is unchanged. This is a behavior-preserving, GUI-only refactor. The TUI presenter feeds the same map later in the stack (#12601). **Reviewing (3 files):** `app.rs` is the substance — the map, its accessors, and the call-site swaps. `presenter.rs` wires the GUI render pass to report embeddings. The test swaps `presenter.ancestors()` → `ctx.view_ancestors()`. ## Stack `master` → **#12413 (this)** → #12633 → #12634 → #12601 ## Testing - [x] `cargo check -p warpui_core -p warp -p warpui` clean; `cargo nextest -p warpui_core` 279 passed / 7 skipped. - No manual run: no behavioral change. ## Agent Mode - [x] Warp Agent Mode CHANGELOG-NONE --------- Co-authored-by: Oz <oz-agent@warp.dev>

## Description * Add `tui` cargo feature flag * Add `TuiElement` interface which diverges from gui `Element` * Add TUI-specific mirrors of `View` traits and APIs; these depend on `TuiElement` * Abstract out `AnyView to wrapper "router" `StoredView` enum which delegates to `AnyView`/`AnyTuiView` wrapper * Implement initial `Tui` presenter types - event context, presentation context * Move all existing GUI elements to re-exported GUI submodule of elements ## Stack #12413 → **#12633 (this)** → #12634 → #12601 ## Testing - [x] `cargo check -p warpui_core -p warp -p warpui` clean in **both** default and `--features tui`. - [x] `cargo nextest -p warpui_core`: 286/7 (default), 311/7 (`--features tui`). ## Agent Mode - [x] Warp Agent Mode CHANGELOG-NONE --------- Co-authored-by: Oz <oz-agent@warp.dev>

…ration Adds the TUI presenter (presenter/tui.rs: lays out and paints a root element tree and reports view embeddings into the neutral view hierarchy) and the crossterm runtime (runtime/: the alternate-screen draw+event loop, renderer, and crossterm -> warp event conversion), dispatching typed actions through the shared responder chain. Drops the scoped #[allow(dead_code)] from the seam slice now that the runtime drains those event.rs methods/fields and constructs TuiPresentationContext. Includes the end-to-end tui_integration test.
