Extends SECTION_DEFAULTS so the out-of-the-box TUI shows the turn as
a live transcript (reasoning + tool calls streaming inline) instead of
a wall of `▸` chevrons the user has to click every turn.
Final default matrix:
- thinking: expanded
- tools: expanded
- activity: hidden (unchanged from the previous commit)
- subagents: falls through to details_mode (collapsed by default)
Everything explicit in `display.sections` still wins, so anyone who
already pinned an override keeps their layout. One-line revert is
`display.sections.<name>: collapsed`.
Copilot review on #14968 caught that the early returns gated on the
global `detailsMode === 'hidden'` short-circuited every render path
before sectionMode() got a chance to apply per-section overrides — so
`details_mode: hidden` + `sections.tools: expanded` was silently a no-op.
Three call sites had the same bug shape; all now key off the resolved
section modes:
- ToolTrail: replace the `detailsMode === 'hidden'` early return with
an `allHidden = every section resolved to hidden` check. When that's
true, fall back to the floating-alert backstop (errors/warnings) so
quiet-mode users aren't blind to ambient failures, and update the
comment block to match the actual condition.
- messageLine.tsx: drop the same `detailsMode === 'hidden'` pre-check
on `msg.kind === 'trail'`; only skip rendering the wrapper when every
section resolves to hidden (`SECTION_NAMES.some(...) !== 'hidden'`).
- useMainApp.ts: rebuild `showProgressArea` around `anyPanelVisible`
instead of branching on the global mode. This also fixes the
suppressed Copilot concern about an empty wrapper Box rendering above
the streaming area when ToolTrail returns null.
Regression test in details.test.ts pins the override-escapes-hidden
behaviour for tools/thinking/activity. 271/271 vitest, lints clean.
- domain/details: extract `norm()`, fold parseDetailsMode + resolveSections
into terser functional form, reject array values for resolveSections
- slash /details: destructure tokens, factor reset/mode into one dispatch,
drop DETAIL_MODES set + DetailsMode/SectionName imports (parseDetailsMode
+ isSectionName narrow + return), centralize usage strings
- ToolTrail: collapse 4 separate xxxSection vars into one memoized
`visible` map; effect deps stabilize on the memo identity instead of
4 primitives
The activity panel (gateway hints, terminal-parity nudges, background
notifications) is noise for the typical day-to-day user, who only cares
about thinking + tools + streamed content. Make `hidden` the built-in
default for that section so users land on the quiet mode out of the box.
Tool failures still render inline on the failing tool row, so this
default suppresses the noise feed without losing the signal.
Opt back in with `display.sections.activity: collapsed` (chevron) or
`expanded` (always open) in `~/.hermes/config.yaml`, or live with
`/details activity collapsed`.
Implementation: SECTION_DEFAULTS in domain/details.ts, applied as the
fallback in `sectionMode()` between the explicit override and the
global details_mode. Existing `display.sections.activity` overrides
take precedence — no migration needed for users who already set it.
Trim comment noise, remove redundant typing, normalize sticky prompt viewport args to top→bottom order, and reuse one sticky viewport helper instead of duplicating the math.
Sticky prompt selection only considered the top edge of the viewport, so it could keep showing an older user prompt even when a newer one was already visible lower down. Suppress sticky output whenever a user message is visible in the viewport and cover it with a regression test.
- providers.ts: drop the `dup` intermediate, fold the ternary inline
- paths.ts (fmtCwdBranch): inline `b` into the `tag` template
- prompts.tsx (ConfirmPrompt): hoist a single `lower = ch.toLowerCase()`,
collapse the three early-return branches into two, drop the
redundant bounds checks on arrow-key handlers (setSel is idempotent
at 0/1), inline the `confirmLabel`/`cancelLabel` defaults at the
use site
- modelPicker.tsx / config/env.ts / providers.test.ts: auto-formatter
reflows picked up by `npm run fix`
- useInputHandlers.ts: drop the stray blank line that was tripping
perfectionist/sort-imports (pre-existing lint error)
If the gateway returns two providers that resolve to the same display name
(e.g. `kimi-coding` and `kimi-coding-cn` both → "Kimi For Coding"), the
picker now appends the slug so users can tell them apart, in both the
provider list and the selected-provider header. No-op when names are
already unique.
Refs #10526 — the Python backend dedupe from #10599 skips one alias, but
user-defined providers, canonical overlays, and future regressions can
still surface as indistinguishable rows in the picker. This is a
client-side safety net on top of that.
Adds useGitBranch hook (async, cached, 15s TTL) and fmtCwdBranch
helper so the footer shows `~/repo (main)` instead of just `~/repo`.
Degrades silently when git is unavailable or cwd is outside a repo.
Partial fix for #12267 (TUI portion; #12277 covers the Python side).
Sticky prompt:
The loop was skipping `first` (the first row in the viewport) when
looking for a user message scrolled above the top edge. If `first`
itself was a user row that had just ticked above the viewport, we'd
fall through the early-return guard (`role === 'user' && !above`),
then walk from `first - 1` backward — never rechecking `first`, never
finding anything, returning '' and leaving the sticky empty. This is
why it felt "stuck" at the start: one-turn sessions with the user row
exactly at/near the top never surfaced the breadcrumb.
Collapsed the two branches into one loop starting at `first`: nearest
user wins — still-on-screen → empty (redundant to echo), already
above → text. Same semantics, covers the gap.
Scrollbar:
`useSyncExternalStore` snapshot was `scrollTop:vp:scrollHeight` —
scrollHeight ticks up by ~1 row on every streamed chunk, forcing a
re-render per chunk. Quantized snapshot to the displayed values
(`thumbTop:thumbSize:vp`) so we only re-render when the bar actually
changes. Drops render count per turn by ~100x during streaming and
stops the "constantly resizes" flicker.
Hoist turn state from a 286-line hook into $turnState atom + turnController
singleton. createGatewayEventHandler becomes a typed dispatch over the
controller; its ctx shrinks from 30 fields to 5. Event-handler refs and 16
threaded actions are gone.
Fold three createSlash*Handler factories into a data-driven SlashCommand[]
registry under slash/commands/{core,session,ops}.ts. Aliases are data;
findSlashCommand does name+alias lookup. Shared guarded/guardedErr combinator
in slash/guarded.ts.
Split constants.ts + app/helpers.ts into config/ (timing/limits/env),
content/ (faces/placeholders/hotkeys/verbs/charms/fortunes), domain/ (roles/
details/messages/paths/slash/viewport/usage), protocol/ (interpolation/paste).
Type every RPC response in gatewayTypes.ts (26 new interfaces); drop all
`(r: any)` across slash + main app.
Shrink useMainApp from 1216 -> 646 lines by extracting useSessionLifecycle,
useSubmission, useConfigSync. Add <Fg> themed primitive and strip ~50
`as any` color casts.
Tests: 50 passing. Build + type-check clean.
