# Changelog

All notable changes to `move` are documented here.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

### Added
- Random pattern selection: `-r` / `--random`, and `random` as a value for
  `--pattern` and the `pattern` config key. Every time a sweep is triggered,
  a different movement pattern is chosen, so the motion varies across the day
  instead of repeating one shape. Two rules keep it predictable: the same
  pattern is never chosen twice in a row, and the pick happens once per
  trigger — in loop mode it holds for the whole loop run rather than changing
  mid-run. The pick is a real strategy, so `--verbose` logs the concrete
  pattern name and a pick with an infinite loop path (`line`, `diagonal`)
  still bounces edge-to-edge under `--loop`.

  `-r` is defined as sugar for `--pattern random`, so passing both is
  rejected (exit `2`) unless they agree: `move -r -p arc` is an error, while
  `move -r -p random` is a no-op. There is no `random` boolean config key —
  the file spells it `"pattern": "random"`.

  `random` is deliberately not a registry entry: it has no path of its own,
  and the keeper resolves it to a real strategy per sweep. `PATTERN_NAMES`
  therefore still lists only real generators, with the new
  `SELECTABLE_PATTERN_NAMES` covering what a user may select.

### Changed
- `parseCliArgs` now takes its argument list as an optional parameter
  (defaulting to the real command line), so the flag surface is unit-testable
  without touching `process.argv`. Adds `tests/cli.test.ts`, which previously
  had no coverage.

## [1.4.0] - 2026-08-17

### Added
- Loop mode: `-l` / `--loop` (and the `loop` config key) keep the mouse
  moving after a sweep is triggered until real user activity is detected,
  instead of firing a single sweep. In loop mode the cursor is never restored
  between iterations, so `line` and `diagonal` bounce edge-to-edge across the
  screen (a roaming-DVD effect) rather than stopping at the first edge.
  Patterns with a finite path (`jitter`, `walk`, `arc`, `figureEight`) chain
  that path cycle after cycle. Interruption remains mouse-movement only.

### Changed
- Simplified on-screen confinement to a single policy: the executor now
  reflects every pattern's out-of-range coordinates back inside the screen.
  The `abort` and `clamp` bounds policies (and the per-strategy `bounds`
  field) were removed. `abort` truncated a sweep at the first edge and `clamp`
  could park the cursor against an edge — both counter to keeping the cursor
  moving — while `reflect` bounces and keeps going. Behavior is unchanged for
  every pattern at normal cursor positions; the only differences are at a
  screen edge, where motion now bounces instead of stopping. No config keys,
  flags, or pattern names changed.

## [1.3.3] - 2026-08-17

### Changed
- `install.sh` now installs the newest published tag by default instead of
  tracking the `master` branch, so the plain `curl ... | sh` one-liner
  installs a real release and reports its version (e.g. `v1.3.2`). The tag is
  resolved from the Gitea tags API; if that lookup fails (offline, API
  unreachable, or no tags yet) it falls back to `master`, preserving the old
  behavior. Set `MOVE_VERSION` to pin an explicit branch or tag as before.

## [1.3.2] - 2026-08-17

### Added
- `install.sh` is now interactive. When it finds an existing install and a
  controlling terminal is available, it reports what's there and asks before
  replacing it, instead of leaving `MOVE_FORCE` as the only control. If a
  config file already exists it asks separately whether to reseed it from the
  shipped defaults. Both questions are asked before anything is downloaded or
  deleted, so declining changes nothing.
- `MOVE_RESEED_CONFIG=1` overwrites the user config with the shipped defaults
  without prompting, for unattended use. The previous file is kept as
  `config.json.bak`; the same backup is written when reseeding is confirmed
  at the prompt.

### Changed
- `MOVE_FORCE=1` now means "skip every prompt and reinstall unconditionally".
  It deliberately does not touch the user config, so automation that
  reinstalls the CLI can't take customizations down with it.
- Existing-install detection looks for the install tree and the wrapper, not
  just the `.installed-version` marker, so a half-finished or hand-moved
  install is caught rather than silently overwritten.

### Fixed
- Installing a *different* version over an existing one used to wipe and
  replace it with no warning; only an exact version match was ever reported.
  That case now prompts. With no terminal (CI, cron, container builds) the
  previous non-interactive behavior is preserved exactly: an identical
  version is a no-op, a different version is replaced.

## [1.3.1] - 2026-08-14

### Added
- `docs/execution-happy-path.md`: a sequence diagram (plus invariants) tracing
  a clean idle-triggered sweep end to end, linked from the README.

### Fixed
- Stale comments corrected to match the current code: the `install.sh` /
  `uninstall.sh` header curl URLs pointed at a nonexistent repo-root path
  (they live under `scripts/`), so the documented command 404'd; `move.ts`'s
  module list omitted `editor.ts` and the `--edit` step; and `config.ts` still
  described a removed pixel unit.

## [1.3.0] - 2026-08-14

### Added
- Pluggable movement strategies. New `-p, --pattern <name>` flag and
  `pattern` config key select how the cursor moves: `line` (default,
  unchanged behavior), `diagonal`, `jitter`, `walk`, `arc`, `figureEight`.
  Each pattern owns its own size and step count as constants; there is no
  user knob for sweep magnitude.
- Pattern names are matched leniently: case and separators are ignored, so
  `figureEight`, `figure-eight`, `figure_eight`, and `FIGUREEIGHT` are all
  accepted (on the CLI and in the config file) and resolve to the canonical
  name.
- `src/device.ts`: injectable `Device` seam over nut.js, enabling unit
  tests for movement without the native binary or a real screen.
- `src/strategies.ts`: pure, per-pattern path generators plus the registry
  and name validation.
- `src/executor.ts`: single `executePath` driver owning bounds policy
  (`abort`/`clamp`/`reflect`), pacing, interrupt detection, and restore.
- Test suites for strategies, the executor (all bounds policies, rounding,
  interrupt), and the keeper loop.

### Changed
- `simulateActivity` no longer hardcodes a straight-line sweep; it selects a
  strategy from the registry and delegates execution to `executePath`. The
  default `line` pattern is byte-for-byte the previous behavior.
- Interrupt detection now compares against the last *commanded* (rounded)
  point rather than an ideal target, so fractional/curved paths don't
  self-trip.
- `mouse.config.autoDelayMs = 0` moved from `runKeeper` into
  `createNutDevice` — the single place nut.js is wired up.
- `runKeeper(config, device?)` accepts an injected device for testing.
- Interrupt detection tolerates a small (2px) gap between the commanded and
  read-back cursor position, and the `clamp`/`reflect` patterns stay a few
  pixels off the screen edge. Together these avoid false "user activity"
  aborts from sub-pixel cursor placement on scaled or multi-monitor setups,
  which the new edge-seeking patterns would otherwise hit. `line` (policy
  `abort`) is unaffected.

### Removed
- `-n, --step-count` flag and the `stepCount` / `stepSize` config keys. Sweep
  size and step count are now intrinsic to each movement pattern, not user
  knobs. Config files that still contain these keys keep working: the loader
  ignores them with a one-line notice instead of rejecting them, so existing
  installs (all seeded with `stepCount`) don't break on upgrade. The removed
  CLI flag, however, is a hard error like any other unknown option.

## [1.2.0] - 2026-06-17

### Added
- `-e, --edit` flag opens the resolved config file in `$EDITOR`.

### Changed
- `keeper.ts` (and `@nut-tree-fork/nut-js`) is lazy-imported, so `--help`
  and `--version` skip the nut.js load and start ~10x faster.

## [1.1.1] - 2026-06-17

### Changed
- Tests moved from `src/` to a top-level `tests/` directory.
- `tsconfig.json` sets `"types": ["bun"]` so VS Code resolves `bun:test`.

### Fixed
- `package.json` version now matches the published tag.

## [1.1.0] - 2026-06-17

### Added
- JSON config file support at `${XDG_CONFIG_HOME:-~/.config}/move/config.json`.
  Precedence: CLI flags > config file > defaults. Strict validation.
- `-C, --config <path>` to override the default config path.
- Installer seeds `config.json` with project defaults on fresh install only.
- Bun test suite for `resolveConfig` and `loadConfigFile`.

### Changed
- Installer scripts now live in `scripts/`.
- `verbose` is now a first-class `Config` field; `resolveVerbose` removed.
- `CliError` extracted into `src/errors.ts`.
- `defaultConfigPath()` throws when both `$XDG_CONFIG_HOME` and `$HOME` are unset.
- `mouse.config.autoDelayMs = 0` moved into `runKeeper` (no module-load side effect).
- Runtime errors go through a `failRuntime` helper that mirrors `failUser`.
- `keeper.ts` declares a named `Logger` interface.
- `dev-setup.sh` is now POSIX `sh`.
- `tsconfig.json`: enabled `noUncheckedIndexedAccess` and `resolveJsonModule`.

## [1.0.1] - 2026-06-17

### Added
- End-user `install.sh` runnable via `curl ... | sh`. XDG-respecting, idempotent.
- `uninstall.sh` removes the wrapper and install tree; leaves Bun and user
  config alone.
- `dev-setup.sh` for contributors.

### Removed
- `DISTRIBUTION-PLAN.md` (design notes, superseded by the implementation).

## [1.0.0] - 2026-06-15

Initial release.

### Added
- `move` CLI for keeping presence-tracking apps marked Available by nudging
  the cursor after a configurable idle period.
- Flags: `-h/--help`, `-v/--version`, `-m/--move-interval`,
  `-c/--check-interval`, `-d/--step-delay`, `-n/--step-count`, `-V/--verbose`.
- Quiet-by-default logging.
- Source split into `src/{move,cli,config,keeper}.ts`.
- `bin` entry + shebang so `bun link` registers `move` globally.
