feat(tui): re-baseline pi-tui on 0.84.1 and add fullscreen mode - #47
Merged
Merged
Conversation
Take upstream's re-baselined pi-tui subtree wholesale. The fork carried no pi-tui source files upstream lacks, and upstream already ships the LaTeX renderer the fork had added, so the only local patch to re-apply was the editor's placeCursorFromClick (click-to-position-cursor) along with the render-height it reads. The renderer now splits into TuiMainScreen and TuiAltScreen behind a TUI interface, so the two `new TUI(...)` call sites construct TuiMainScreen and import TUI as a type. Add an env-gated fullscreen mode (ECHADRON_TUI_FULL_SCREEN=1, with the legacy KIMI_CODE_TUI_FULL_SCREEN spelling accepted): the transcript scrolls inside a primary ScrollView with follow-end while the activity, todo, queue, btw and editor containers stack in a bottom dock. Regular mode keeps its existing layout and stays the default.
📝 WalkthroughWalkthroughChangesFullscreen application wiring
Estimated code review effort: 5 (Critical) | ~120 minutes Mergeability Score: 🟡 Moderate · up to The opt-in fullscreen mode preserves the default layout, but the current change can fail Windows native builds on x64-only MSVC environments and can misplace the cursor when clicking CJK, emoji, or wrapped text. These bounded issues should be fixed before merging. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

193-271: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueSplit this test and reduce timing sensitivity.
Two points about this block:
- Line 217 waits 30 ms for a 10 ms hide delay. On a loaded CI machine that margin is small, so the hide assertion at line 219 can fail intermittently. Increase
scrollbarHideDelayMsand the wait, or drive the hide through injected time instead ofsetTimeout.- The block asserts transient painting, hide-after-delay, follow-end growth,
autoandalwaysreservation, and thumb-height scaling. A failure does not identify which behavior broke. Split it into separateitblocks in this same file.🤖 Prompt for AI Agents

239-293: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winIncrease the timing margins in the scrollbar visibility test.
The test configures
scrollbarHideDelayMs: 50and then waits 70 ms. The margin is 20 ms. On a loaded CI machine the timer callback can run late, or the awaited render can consume most of the margin. The same pattern appears in the flash test at Lines 1189-1200, where the flash duration is 80 ms and the wait is 100 ms.Raise the wait time relative to the configured delay, for example a 50 ms delay with a 200 ms wait. This keeps the assertions unchanged and reduces flake risk.

In `@packages/pi-tui/native/win32/build.mjs`:
- Around line 93-107: Update canUseMsvc to validate both x64 and arm64 MSVC
environments before returning success, using the appropriate architecture
arguments for each probe. Only select MSVC when both target probes succeed;
otherwise preserve the existing MinGW fallback.
In `@packages/pi-tui/native/win32/README.md`:
- Line 6: Replace the invalid npm-script command in
packages/pi-tui/native/win32/README.md at lines 6 and 19 with the direct Win32
build invocation, and update the Darwin README similarly with its direct build
command. In packages/pi-tui/native/win32/build.mjs at line 201, update the
--help output to advertise the same direct Win32 command; use the
repository-root commands specified by the review.
Apply the same fix in `@packages/pi-tui/native/darwin/README.md` around lines 3 -

In `@packages/pi-tui/src/components/editor.ts`:
- Around line 691-710: Update placeCursorFromClick to convert the terminal
display column into a grapheme-boundary UTF-16 offset instead of adding
visualCol directly to visual.startCol. Use the editor’s existing grapheme
segmentation and display-width logic, clamp the click to the current visual
segment’s end so right padding cannot enter a later segment, and set the cursor
to the nearest valid grapheme boundary.
In `@packages/pi-tui/test/render-churn-bench.ts`:
- Line 16: Update the run instruction in the benchmark file to use the correct
package directory, packages/pi-tui, instead of packages/tui.
In `@packages/pi-tui/test/tui-render.test.ts`:
- Around line 119-136: Update the test around TuiMainScreen so tui.stop() runs
in a finally block that wraps the log assertion, ensuring cleanup occurs even
when the assertion fails while preserving the existing test and directory
cleanup flow.

Fullscreen was only reachable through an env var, which makes it undiscoverable and awkward to keep on. Add `[tui] tui_mode` with an `inline` default and a Display mode entry under /settings; the env override stays for one-off runs and now only applies when set. The screen is chosen when the TUI is constructed, so selecting a mode persists it and asks for a restart rather than pretending to swap live.
placeCursorFromClick added a terminal display column to a UTF-16 string offset. The two units only agree for narrow ASCII: a CJK glyph occupies two cells and an emoji several code units, so a click landed at the wrong offset and could split a grapheme. Walk the clicked visual segment grapheme by grapheme, spending display width, and clamp to the end of that segment so a click in the trailing padding cannot spill into the next one. Covered by editor-click.test.ts, kept in its own file so it does not conflict on the next re-baseline. Also correct the native win32 README: it pointed at a packages/tui path and a build:native:win32 script that this vendored copy does not define, so the documented command could not work. Point at the builder directly.
SettingsSelectorComponent ran every choice through a hand-written whitelist before calling onSelect. Rows added to the menu but missed in that list rendered normally and did nothing when picked — no dispatch, no error. Both recently added rows were affected: Display mode and Secondary model. Derive the guard from SETTINGS_SELECTION_VALUES so the menu and the guard cannot drift, and assert every menu row is selectable. The previous test compared that list against itself, which proved nothing about whether a selection reaches its handler.
