* feat(cli): support refreshInterval in statusLine for periodic refresh The statusLine (#3311) re-runs only when Agent state changes (token count, model, git branch, etc.). Commands that display *external* data — a clock, rate-limit counters, CI build status — have no Agent event to hook into and go stale between messages. Add an optional `ui.statusLine.refreshInterval` field (seconds, minimum 1) that schedules a setInterval alongside the existing event-driven updates. Overlap with state-change debounce is safe: `doUpdate` kills any in-flight child and bumps the generation counter, so only the most recent output reaches the footer. Validation lives in `getStatusLineConfig`: - Must be `number`, `Number.isFinite(...)`, `>= 1` - Anything else is silently dropped (no interval scheduled) No changes to the default behavior — configs without `refreshInterval` behave exactly as before. * fix(cli): yield periodic statusLine tick when previous exec is in flight Review feedback on #3383: with `refreshInterval: 1` and a command whose real exec time exceeds 1s, each tick was unconditionally calling `doUpdate()` — which kills the in-flight child and bumps the generation counter — so the prior exec's callback was always discarded as stale. `setOutput` was never reached and the statusline stayed empty until `refreshInterval` was removed or the command became faster. Guard the interval callback with an `activeChildRef` check so a pending exec is allowed to finish. State-change triggers (model switch, token count, branch, etc.) still go through `scheduleUpdate` → `doUpdate` directly and legitimately preempt stale children; only the periodic tick yields. The existing 5s exec timeout is still the hard ceiling. Also drop the redundant `'refreshInterval' in raw` check — the `typeof raw.refreshInterval === 'number'` guard already excludes missing / undefined values. Tests: - Add regression test `'skips periodic ticks while a previous exec is still running'` — three ticks during one unfinished exec trigger zero new spawns; the next tick after callback completion does spawn. - Update two existing tests to resolve the mount exec before expecting subsequent ticks (the old tests implicitly relied on the starvation behavior being tolerated). * test(cli): assert user-visible lines state in starvation regression Self-review insight: the existing `skips periodic ticks while a previous exec is still running` test only counted `exec` calls — it confirmed the guard prevents redundant spawns, but would have silently passed even if the eventual callback was still being discarded as stale (which is the actual user-visible symptom of the starvation bug). Add `expect(result.current.lines).toEqual(['done'])` after resolving the mount's pending callback. Without the guard, generationRef would have bumped 3 times during the yielded ticks, the callback's captured gen would fail the stale check, `setOutput` would never fire, and `lines` would stay empty — now caught explicitly. * perf(cli): dedupe statusLine output to skip unchanged Footer re-renders Review feedback on #3383 (narrow terminal stacking): when `refreshInterval` fires at 1s and the command output is unchanged, the mount-and-setOutput cycle still allocates a new array and triggers a Footer re-render. Under certain narrow-terminal conditions, Ink's erase-line accounting mis-counts wrapped rows and stale content accumulates on screen. The Footer-layout root cause is in #3311's narrow-mode flex setup and Ink's truncate semantics, which is out of scope for this PR. But we can cut the re-render surface here by preserving the `lines` array reference when the command produces identical output — a strict Pareto improvement for any caller (clock-style statuslines with second-precision still re-render; rate-limit / branch / CI-status style statuslines that change infrequently stop triggering work every tick). Tests: - `preserves the same lines array reference when output is unchanged` asserts referential equality after a re-exec with identical stdout. - `produces a new reference when output changes` guards against over-eager dedup that would miss legitimate updates. * fix(cli): stabilize Footer rendering in narrow terminals Narrow-terminal E2E feedback on #3383: with `refreshInterval` at 1s, empty lines were accumulating above the input prompt each tick. Root cause is in the Footer flex layout — originally from #3311 — where Ink miscounts logical rows vs the physical rows the terminal actually uses. Two adjustments, both idiomatic (used elsewhere in the repo already): 1. Left column — `minWidth={0}`. Without this, Yoga's `min-width: auto` default keeps the Box at its natural content width, so a statusline wider than the terminal doesn't engage `<Text wrap="truncate">`; the text renders at content-width and the terminal wraps it physically. `minWidth={0}` lets the column shrink so the text child can truncate at container width. 2. Right section — `flexWrap="wrap"`. With multiple indicators (sandbox label, debug badge, dream, context-usage) the row can exceed a narrow terminal's width. Without `flexWrap` Ink lays them out in a single logical row, but the terminal physically wraps to two — Ink's erase sequence (`\e[2K\e[1A…` per logical row) then clears one row while two exist, and the extra row ghosts every re-render. With `wrap` Ink tracks the second row explicitly and erases correctly. Together these make the Footer's row count match between Ink's logical view and the terminal's physical view, so frequent re-renders (as `refreshInterval` enables) stop accumulating ghost rows. Needs verification in a real narrow TTY — from this environment I can reason about the flex semantics and confirm both props are supported by Ink's Box, but actually observing ghost-row elimination requires process.stdout.columns on a real terminal. * Revert "fix(cli): stabilize Footer rendering in narrow terminals" This reverts commit |
