feat(ui): snow winter scene, rain panel size, and snow fixes#13
Merged
Conversation
… canvas Add snow animation with falling flakes, unbounded ground accumulation, log cabin with chimney smoke and lit windows, random trees with frost, and a staged snowman. Introduce rain_panel_size (compact/comfortable/tall) with terminal clamping via panel height measurement. Default comfortable (8 rows). Settings TUI and README updated.
- Break rainVisible vs measured header cycle (rainStripIncludedInLayoutMeasure + header gate)\n- Add snow_accumulation_rate (1–8× per landing) and settings TUI row\n- Trees spawn at init; snowman elevated above ground bank; bolder styling and split parens on base

290-294: Stream init skips snow tuning.Unlike the static ctor (line 213) which calls
base.applyGardenTuning(base.rainBg), the stream path only wires garden tuning viaSetGardenTuningand never appliesSetSnowAccumPerLanding. IfRainAnimationMode == "snow",snowAccumPerLandingremains 0 until the firsttea.WindowSizeMsg(line 348) runsapplyGardenTuning. In practice the first WindowSizeMsg arrives early so the runtime guard atrain_bg.go:788(if add < 1 { add = 1 }) masks this, but the two initializers drifting apart will bite the next time snow-only tuning is added.♻️ Proposed alignment

747-773: Clamp loop allocates a fresh RainBackground per probe.
clampedRainBackgroundHeightlinearly steps frompresetdown to 3, and eachrainPanelFitsHeightcall allocates a newRainBackground(plusFlowers/CloudRow/garden state) and runs two binary-searchedlipgloss.Heightmeasurements of the rendered panel. This runs on everytea.WindowSizeMsg, andUpdate'sWindowSizeMsghandler itself reconstructsm.rainBgright after. Not a correctness issue, but worth reusing a single probeRainBackground(e.g. mutate itsHeight/re-Reset) or short-circuiting once the first fitting height is found via binary search rather than linear scan when responsiveness matters on large terminals.

Inline comments:
In `@internal/ui/config_view.go`:
- Around line 199-217: The switch in snowAccumLabel incorrectly maps unspecified
values (5 and 7) to "1×"; instead compute n :=
config.SnowAccumPerLanding(cfg.UI.SnowAccumulationRate) and return a dynamic
label using that value (e.g. format "%d×") so any integer 1–8 is shown
correctly; update snowAccumLabel to handle nil cfg as before, then use
fmt.Sprintf with the computed n to produce the label.
In `@internal/ui/rain_bg_test.go`:
- Around line 298-351: Tests call the deprecated global rand.Seed which triggers
staticcheck SA1019; make RainBackground (and its snow scene) accept an injected
*rand.Rand (add RainBackground.SetRand(r *rand.Rand) and use that RNG in
spawnDrop/spawnDropGarden/snowNoteFlakeLand/snowAdvanceScene instead of
package-level rand) so tests can do rb.SetRand(rand.New(rand.NewSource(42))) for
deterministic behavior; if that refactor is out of scope for this PR, suppress
the linter in the test by replacing the rand.Seed calls with a
`//nolint:staticcheck` comment on the same line to unblock CI.
In `@internal/ui/snow_scene.go`:
- Around line 61-68: The current Snowman placement logic sets rb.SnowmanX to
rb.Width-5 (or falls back left of the cabin) which lets the snowman hat/scarf
overlap the cabin for mid-range widths; change the computation of rb.SnowmanX to
ensure a 3-column buffer to the right of the cabin by taking rb.SnowmanX =
max(rb.SnowCabinLeft + snowCabinW + 3, rb.Width - 5) and then clamp that value
into the valid horizontal bounds (at least 2 and at most rb.Width-3) before
using it; update the branch that sets rb.SnowmanX (and any fallback logic) to
use these max/clamp calculations and reference rb.SnowmanX, rb.SnowCabinLeft,
snowCabinW and rb.Width when making the change.
- Around line 289-297: snowPaintLine misuses the range loop index (byte offset)
causing multi-byte runes to be placed at wrong columns; fix by iterating runes
and maintaining a separate column counter (e.g., col) instead of using the range
index i, so compute x := left + col and call rb.snowPaintCell(cells, x, y,
string(r), st) while incrementing col for each rune; update the loop in
snowPaintLine to use for _, r := range line with a column counter (or iterate
over []rune(line)) so multi-byte characters like '█' and '≋' map to consecutive
terminal cells.

+### Snow mode and rain panel size
+
+`rain_animation_mode = "snow"` uses the same animation strip for a winter scene:
+falling snowflakes, snow that keeps piling on the ground, a small log cabin
+with chimney smoke and lit windows, occasional evergreen trees that pick up
+frost, and a snowman that grows in stages (two spheres, then face, pipe, and
+top hat).
+
+`rain_panel_size` controls how many terminal rows the animation canvas uses:
+`compact` (5), `comfortable` (8, default), or `tall` (11). The TUI clamps the
+height automatically so the bordered panel still fits short terminals.

### Config file, locks, and crashes
**Registry (`repos.toml`)** — Writes use a cross-process lock file (`repos.toml.lock`), atomic replace, and stale-lock detection (owner PID). If a process dies mid-run you may still see a leftover lock: the CLI prompts to remove it when safe, or you can use **`--force-unlock-registry`** in scripts. This is the same class of “stale lock / don’t corrupt the database” problem as other multi-repo tools; treat lock removal like any other forced unlock — only when you are sure no other `git-rain` is running.

snowPaintLine used the range index as x offset; in Go that index is the UTF-8 byte position, so multi-byte glyphs (█, ≋, ─) were spaced incorrectly. Track a rune/column counter for correct cell placement. Co-authored-by: Ben Schellenberger <bschellenberger2600@users.noreply.github.com>
Replace fixed width slots with rejection sampling: tree count scales with width and height, minimum trunk spacing scales with width, canopy uses a 3-column footprint check vs cabin/snowman. Add tests for spacing and valid sites.

- Around line 460-471: The scarf is being drawn above the face because scarfY is
set to feetY - 3 (above faceY = feetY - 2); change the scarf row to sit below
the face by setting scarfY to faceY + 1 (or feetY - 1) where scarfY is computed,
and keep the existing rb.snowPaintLine call that uses scarfY so the scarf
renders at the neck between head and body instead of above the face (update the
variable assignment near the snowman layout code that defines scarfY).
- Around line 398-412: The loop in snow_scene.go repeatedly calls
lipgloss.NewStyle() per cell; hoist the three depth styles (e.g.,
sLight="#E3F2FD", sMid="#BBDEFB", sDeep="#90CAF9") and the faint variant once
outside the for loop and pick the appropriate precomputed style inside it
instead of allocating new ones each iteration; update the branch that sets st
and the faint usage (st.Faint(true)) to use the precomputed faint-style
variable, keeping rb.SnowGround, snowGroundGlyph and rb.snowPaintCell calls
unchanged.
- Around line 74-101: In snowSpawnInitialTrees the slots slice can contain
duplicate or too-close x positions and snowFootprintFree only checks
cabin/snowman, so dedupe and enforce spacing before appending: compute a unique,
sorted list of candidate x positions from slots, then for each candidate check
snowFootprintFree(x,1) AND ensure no existing rb.SnowTrees (including ones just
appended in this call) have abs(tree.x - x) < MIN_GAP (choose MIN_GAP=2 or 3),
and skip candidates that are outside safe bounds or violate the gap; finally
append only when both checks pass (update references to snowSpawnInitialTrees,
slots, snowFootprintFree, rb.SnowTrees, and the snowTree struct).

Cursor Bugbot has reviewed your changes and found 2 potential issues.
Bugbot Autofix prepared fixes for both issues found in the latest run.
- ✅ Fixed: Snow accumulation rate not applied at stream startup
- NewRepoSelectorModelStream now assigns the rain background and calls applyGardenTuning so snow accumulation rate is applied on startup, not only after WindowSizeMsg.
- ✅ Fixed: Trees placed at snowman's future position during init
- snowFootprintFree now treats the snowman reservation as active during phase none when Width >= 18, matching when the snowman will spawn so initial trees avoid that band.

+### Snow mode and rain panel size
+
+`rain_animation_mode = "snow"` uses the same animation strip for a winter scene:
+falling snowflakes, snow that keeps piling on the ground, a small log cabin
+with chimney smoke and lit windows, occasional evergreen trees that pick up
+frost, and a snowman that grows in stages (two spheres, then face, pipe, and
+top hat).
+
+`rain_panel_size` controls how many terminal rows the animation canvas uses:
+`compact` (5), `comfortable` (8, default), or `tall` (11). The TUI clamps the
+height automatically so the bordered panel still fits short terminals.
+
+```toml
+[ui]
+rain_animation_mode = "snow"

### Config file, locks, and crashes
**Registry (`repos.toml`)** — Writes use a cross-process lock file (`repos.toml.lock`), atomic replace, and stale-lock detection (owner PID). If a process dies mid-run you may still see a leftover lock: the CLI prompts to remove it when safe, or you can use **`--force-unlock-registry`** in scripts. This is the same class of “stale lock / don’t corrupt the database” problem as other multi-repo tools; treat lock removal like any other forced unlock — only when you are sure no other `git-rain` is running.

Summary
Adds snow
rain_animation_modewith a winter strip (flakes, drifting ground snow, cabin, smoke, evergreens, staged snowman), rain_panel_size presets (compact / comfortable / tall) with runtime clamping, and follow-up fixes for stability and polish.Fixes (second commit)
rainVisibleno longer calls layout measurement that re-entered the header; measurement usesrainStripIncludedInLayoutMeasure()while the live view still usesrainVisible().snow_accumulation_rate(1–8× depth per landing), settings row in snow mode, loader default, tests.Tests
go test ./...(pass)Docs
README + example TOML updated on the base commit for snow and panel size.
Note
Medium Risk
Changes TUI layout measurement and visible rain-strip logic; mistakes could hide the animation or mis-size panels, but scope is UI-only with added tests.
Overview
Adds
snowas arain_animation_modewith a new winter strip: falling flakes, per-column ground depth, cabin/smoke/trees/frost, and a snowman that advances from nearby landings. Scene logic lives insnow_scene.goand hooks intoRainBackgroundupdate/render paths.Introduces
rain_panel_size(compact/comfortable/tall) andsnow_accumulation_rate(1–8× depth per landing viaSnowAccumPerLanding). Defaults, loader normalization, example TOML, and README are updated; the settings TUI adds Rain panel size, snow in the mode list, and a Snow accumulation row when snow is selected (garden extension rows are generalized the same way).The animation canvas is no longer fixed at five rows: height comes from the preset and
clampedRainBackgroundHeight, which shrinks the canvas until main and ignored panels fit. Fixes a stack overflow by measuring layout withrainStripIncludedInLayoutMeasure()and gated header helpers instead ofrainVisible()during capacity math;rainVisible()still decides whether to paint the strip once sizes are known.Reviewed by Cursor Bugbot for commit b21ba56.
