Add CHANGELOG.md

v1.2.0
Notable changes since v1.1.1: - New -e/--edit flag opens the active config file in $EDITOR. - Lazy import of keeper.ts so --help and --version skip the nut.js native load on cold start. - Various audit cleanups: failRuntime() mirror, named Logger interface, errors.ts module, autoDelayMs moved out of module-load side effects, defaultConfigPath guards against unset HOME, noUncheckedIndexedAccess enabled in tsconfig. - Added Bun test suite (34 tests across resolveConfig, loadConfigFile, editConfig). - scripts/dev-setup.sh made POSIX-portable.

+# 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).
+
+## [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.

-# Distribution Plan for `move`
-
-**Status:** Tabled 2026-06-15. Revisit after the initial Gitea push lands
-and the repo is publicly reachable at <https://gitea.cahlen.com/nokeo08/Move>.
-
-This document captures the analysis and decisions for distributing the
-`move` CLI as an end-user-friendly tool, so we can resume without redoing
-the discussion.
-
---
-
-## Decisions locked in
-
-| Decision | Choice |
-| -------- | ------ |
-| Primary hosting | Self-hosted Gitea (`https://gitea.cahlen.com/nokeo08/Move`) |
-| Default branch | `master` |
-| Audience | Anyone who finds the repo (broader public-ish) |
-| Effort budget for now | Smallest viable curl-able `install.sh` |
-| Bun handling | Fail with a clear message when missing (no auto-install) |
-| Reinstall behavior | Idempotent via a version-marker file; `MOVE_FORCE=1` overrides |
-| Install location | `~/.local/bin` + `~/.local/share/move` (XDG, no sudo), env-overridable |
-| `move` shim | Bash wrapper script, not symlink |
-| PATH rc files | Never modified; print instructions if PATH isn't right |
-| Uninstaller | In scope; same `curl ... \| sh` pattern |
-| npm publishing | Out of scope |
-| Standalone binaries (`bun build --compile`) | Future work; depends on nut.js native-bundling testing |
-| Homebrew tap | Future work; cheap once releases exist |
-
---
-
-## Distribution-option survey (from the discussion)
-
-Four options were weighed:
-
-1. **Compiled standalone binary** (`bun build --compile`). Best UX (single
-   binary, no Bun needed) but needs per-platform builds, a release
-   pipeline, code signing on macOS, and depends on nut.js's prebuilt native
-   `.node` files bundling correctly under `--compile` — **unverified**.
-2. **Curl-piped installer** — **chosen**. Single command, no clone,
-   source-and-Bun model. Conventions used by bun, deno, rustup, nvm.
-   Slight cold-start cost vs. compiled binary; tradeoff accepted.
-3. **Package-manager distribution** (`bun add -g`, brew). `move` is taken
-   on npm; brew is macOS-centric; both add publishing overhead. Out of
-   scope for first cut.
-4. **Status quo** (clone + `./install.sh` + `bun link`). Developer flow
-   only; will be renamed to `dev-setup.sh`.
-
---
-
-## Target end-user UX
-
-```sh
-curl -fsSL https://gitea.cahlen.com/nokeo08/Move/raw/branch/master/install.sh | sh
-move --help
-```
-
-One command. No clone. No `bun link`. No `chmod`. After this the user has
-a global `move` on their PATH.
-
---
-
-## `install.sh` design (end-user, curl-able)
-
- **Shebang:** `#!/usr/bin/env sh` (POSIX).
- **Strict mode:** `set -eu`. Trap on errors with a clear
-  "install failed at <step>" message.
-
-### Top-to-bottom behavior
-
-1. **Platform detection:**
-   - `uname -s` → `Darwin` / `Linux` / else → "unsupported OS" + exit 1.
-   - `uname -m` → `arm64` / `x86_64` (mapped to `x64`) / else →
-     "unsupported arch" + exit 1.
-   - nut.js supports darwin-arm64/x64, linux-x64, win32-x64. WSL users
-     fall under Linux.
-2. **Bun check:**
-   - `command -v bun` present → continue.
-   - Absent → print
-     `Error: bun is not installed. Install from https://bun.sh (e.g. 'curl -fsSL https://bun.sh/install | bash'), then re-run.`
-     → exit 1.
-3. **Resolve paths:**
-   - `INSTALL_DIR=${MOVE_PREFIX:-$HOME/.local/share/move}`
-   - `BIN_DIR=${MOVE_BIN_DIR:-$HOME/.local/bin}`
-   - `mkdir -p` both.
-4. **Resolve version:**
-   - `VERSION=${MOVE_VERSION:-master}`.
-5. **Idempotence check:**
-   - If `$INSTALL_DIR/.installed-version` exists AND its content equals
-     `$VERSION` AND `${MOVE_FORCE:-0}` is not `1`:
-     - Print `move <version> already installed at $BIN_DIR/move. Set MOVE_FORCE=1 to reinstall, or pass a different MOVE_VERSION.`
-     - Exit 0.
-6. **Clean install dir:** `rm -rf "$INSTALL_DIR"/*` (preserving the dir
-   itself so user-set permissions on it are kept).
-7. **Download source:**
-   - `TARBALL="https://gitea.cahlen.com/nokeo08/Move/archive/${VERSION}.tar.gz"`
-   - `curl -fsSL "$TARBALL" -o "$TMP"` (mktemp) → on failure, fail
-     loudly with the offending URL.
-   - `tar -xzf "$TMP" -C "$INSTALL_DIR" --strip-components=1`
-   - `rm -f "$TMP"`
-8. **Install deps:** `cd "$INSTALL_DIR" && bun install --production`.
-   `--production` skips devDependencies (TypeScript, @types/bun); saves
-   tens of MB and seconds per install.
-9. **Drop the wrapper:**
-   ```sh
-   cat > "$BIN_DIR/move" <<EOF
-   #!/usr/bin/env sh
-   exec bun "$INSTALL_DIR/src/move.ts" "\$@"
-   EOF
-   chmod +x "$BIN_DIR/move"
-   ```
-   Wrapper, not a symlink, so the path is absolute and stable regardless
-   of how the user's shell resolves things.
-10. **Write version marker:** `printf '%s\n' "$VERSION" > "$INSTALL_DIR/.installed-version"`.
-11. **PATH sanity check:**
-    - If `$BIN_DIR` is not on `$PATH`, print:
-      `Warning: $BIN_DIR is not on your PATH. Add this to your shell rc: export PATH="$BIN_DIR:$PATH"`
-    - Do **not** mutate the user's rc files — that breaks the "clean
-      uninstall" contract.
-12. **macOS Accessibility hint** (carried over from current `install.sh`).
-13. **Final message:** `Installed move $VERSION at $BIN_DIR/move. Run 'move --help' to get started.`
-
-### Env vars
-
-| Var | Default | Purpose |
-| --- | ------- | ------- |
-| `MOVE_VERSION` | `master` | Branch or tag to fetch from Gitea. |
-| `MOVE_PREFIX` | `$HOME/.local/share/move` | Source install location. |
-| `MOVE_BIN_DIR` | `$HOME/.local/bin` | Wrapper install location. |
-| `MOVE_FORCE` | unset | Force reinstall even if version marker matches. |
-
---
-
-## `uninstall.sh` design
-
-```sh
-curl -fsSL https://gitea.cahlen.com/nokeo08/Move/raw/branch/master/uninstall.sh | sh
-```
-
-**Behavior:**
-
-1. `set -eu`.
-2. Respect `MOVE_PREFIX` and `MOVE_BIN_DIR` env vars (same defaults as
-   install).
-3. `rm -f "$BIN_DIR/move"`.
-4. `rm -rf "$INSTALL_DIR"`.
-5. Print `Uninstalled. (Bun was not touched.)`.
-
-Does **not** uninstall Bun — that's the user's runtime, not ours.
-
---
-
-## `dev-setup.sh` design (renamed from current `install.sh`)
-
-The current `install.sh` is appropriate for contributors but inappropriate
-as the end-user installer. Rename to `dev-setup.sh`. Content stays nearly
-identical:
-
- Verify Bun is installed (hard-error if missing).
- `bun install`.
- macOS Accessibility hint.
- Trailing message updated to:
-  `Done. Dev workflow: 'bun run start' to run, or 'bun link' to install the global 'move' command. End-user installer is install.sh.`
-
---
-
-## README changes (when we resume)
-
- `## Install` section becomes the curl one-liner targeting `master`, plus
-  a short note about env-var overrides and a pointer to uninstall.
- `## Run` section collapses to `move` / `move --help` for the global
-  install path.
- New `## Uninstall` section with the curl-pipe uninstall command.
- New `## For contributors` section absorbing the existing
-  `bun run start` / `bun run src/move.ts` / `bun link` examples; points
-  at `dev-setup.sh`.
- `## Files` table updates: add `install.sh` (end-user, curl-able),
-  `uninstall.sh` (end-user, curl-able), `dev-setup.sh` (contributor
-  bootstrap).
-
---
-
-## Verification plan (when we resume)
-
-1. `sh -n install.sh` and `sh -n uninstall.sh` — POSIX syntax check.
-2. Local end-to-end with overridden paths:
-   ```sh
-   MOVE_PREFIX=/tmp/movetest MOVE_BIN_DIR=/tmp/movetest/bin ./install.sh
-   /tmp/movetest/bin/move --help
-   ./install.sh                          # second run: already-installed message
-   MOVE_FORCE=1 ./install.sh             # forced reinstall
-   ```
-3. Uninstall against the test prefix; confirm nothing left under it.
-4. Re-run existing acceptance tests (`tsc`, `--help`, `--version`,
-   `--bogus`) — should be unaffected; no source changes in this milestone.
-5. After committing/pushing, end-to-end against the actual Gitea URL.
-
---
-
-## Caveat: Gitea archive URL shape
-
-The plan assumes
-`https://gitea.cahlen.com/nokeo08/Move/archive/<ref>.tar.gz` returns a
-tarball whose top-level directory contains the project files (peeled by
-`--strip-components=1`). This is the standard Gitea archive format, but
-if your Gitea version produces a different layout the installer will need
-a small tweak. The installer should error loudly with the offending URL
-if extraction fails.
-
---
-
-## Open future work (out of scope for the resume session)
-
- Switch `MOVE_VERSION` default from `master` to "latest tag" via the
-  Gitea API (`/api/v1/repos/nokeo08/Move/tags`) once tagged releases are
-  routine.
- Investigate `bun build --compile` + nut.js native-binary bundling for
-  true zero-Bun installs. If it works, layer prebuilt binaries onto the
-  curl installer so users without Bun also get one-command installs.
- Homebrew tap for macOS users (cheap once a release pipeline exists).
- Possible: PowerShell installer (`install.ps1`) for native Windows users
-  without WSL.

 ```

-The installer verifies `bun` is on `PATH` and runs `bun install`. It does
-not auto-install Bun; if Bun is missing it prints a hard error pointing at
-<https://bun.sh>.
+This fetches the latest `master` from Gitea, runs `bun install --production`
+under the install dir, and drops a `move` wrapper on your bin dir.
+
+The installer respects the XDG Base Directory Specification:
+
+- Source lives at `$XDG_DATA_HOME/move` (default `~/.local/share/move`).
+- Wrapper goes to `$XDG_BIN_HOME/move` (default `~/.local/bin/move`).
+  `XDG_BIN_HOME` is the widely-recognized de facto convention; XDG itself
+  doesn't standardize a user bin dir.
+
+Env vars (all optional):
+
+| Var | Default | Purpose |
+| --- | ------- | ------- |
+| `MOVE_VERSION` | `master` | Branch or tag to install. Pin with e.g. `v1.0.0`. |
+| `MOVE_FORCE` | unset | Set to `1` to reinstall when the same version is already present. |
+| `XDG_DATA_HOME` | `$HOME/.local/share` | Where the source tree is installed (under `move/`). |
+| `XDG_BIN_HOME` | `$HOME/.local/bin` | Where the `move` wrapper is placed. |
+
+Bun must already be installed; the installer fails with a clear pointer
+to <https://bun.sh> if it isn't.
+
+If your bin dir isn't on `PATH`, the installer prints the line to add to
+your shell rc. It will not modify rc files for you.

 ## Run

 ```sh
-bun run start
-```
-
-Or directly:
-
-```sh
-bun run src/move.ts
-```
-
-Or install it as a global `move` command via Bun's bin-linking:
-
-```sh
-bun link
 move
+move --help
 ```

-`bun link` registers the `bin.move` entry from `package.json` (`./src/move.ts`,
-which carries `#!/usr/bin/env bun`) as an executable on your `PATH`.
-
 Stop with `Ctrl+C`. If `SIGINT` arrives mid-sweep, the cursor stays at
 whichever step was last commanded — by design.

+## Uninstall
+
+```sh
+curl -fsSL https://gitea.cahlen.com/nokeo08/Move/raw/branch/master/scripts/uninstall.sh | sh
+```
+
+Removes the wrapper at `$XDG_BIN_HOME/move` and the install tree at
+`$XDG_DATA_HOME/move`. Bun stays — it's your runtime, not ours.
+
+Your config file at `$XDG_CONFIG_HOME/move/config.json` is **intentionally
+left behind**, whether you customized it or never touched the seeded
+defaults. The uninstaller prints a one-line notice pointing at the path
+so you can remove it manually if you want:
+
+```sh
+rm -rf "${XDG_CONFIG_HOME:-$HOME/.config}/move"

+## Configuration
+
+`move` reads an optional JSON config file at:
+
+```
+${XDG_CONFIG_HOME:-$HOME/.config}/move/config.json
+```
+
+The installer seeds this file with the default values on a fresh install,
+**only if no file already exists at that path**. Existing configs — yours
+or from a previous install — are never overwritten. If you remove the
+file later, `move` still works: missing defaults fall back to the values
+baked into the binary (which match what was seeded, since both come from
+`scripts/config.default.json`).
+
+Pass `-C` / `--config <path>` to point at a different file; in that mode
+the file must exist.
+
+### Precedence
+
+```
+CLI flags  >  config file  >  built-in defaults
+```
+
+CLI flags always win. The config file fills in any flag the user didn't
+pass on the command line. Built-in defaults fill in anything the file
+doesn't set.
+
+### Example
+
+```jsonc
+{
+  "moveInterval":  240,
+  "checkInterval": 10,
+  "stepDelay":     50,
+  "stepCount":     250,
+  "verbose":       false
+}
+```
+
+All keys are optional; supply only the ones you want to override. Keys
+and units mirror the CLI flags exactly: `moveInterval` and
+`checkInterval` are seconds, `stepDelay` is milliseconds, `stepCount` is
+pixels, `verbose` is a boolean.
+
+### Editing
+
+```sh
+move -e         # or --edit
+move --edit --config /path/to/another.json
+```
+
+Opens the active config file in `$EDITOR` (honors flags in the value,
+so `EDITOR="code --wait"` and `EDITOR=vim` both work). Refuses with
+exit `2` if:
+
+- `$EDITOR` is unset or empty.
+- The target file doesn't exist. (Run `move` once or reinstall to
+  re-seed the default file.)
+
+The editor's own exit code is propagated, so you can chain
+`move -e && move` to validate-by-running after every edit.
+
+### Validation
+
+The loader is strict:
+
+- Root must be a JSON object.
+- Unknown keys are rejected (catches typos like `"movInterval"`).
+- Numeric values must be finite and strictly positive.
+- `verbose` must be a boolean.
+
+Any validation failure prints a message naming the file and the offending
+key to `stderr` and exits `2`.
+
+### Known limitation: `verbose` can be turned on but not off from the CLI
+
+`--verbose` is a presence-only flag (there is no `--no-verbose`). If the
+config file sets `"verbose": true`, the CLI cannot force quiet mode in
+that invocation. Workarounds: edit the file, or point at a different
+file with `--config`.

nokeo08	7777b16540	Add CHANGELOG.md	2026-06-29 12:27:16 -05:00
nokeo08	cff1c482a3	v1.2.0 Notable changes since v1.1.1: - New -e/--edit flag opens the active config file in $EDITOR. - Lazy import of keeper.ts so --help and --version skip the nut.js native load on cold start. - Various audit cleanups: failRuntime() mirror, named Logger interface, errors.ts module, autoDelayMs moved out of module-load side effects, defaultConfigPath guards against unset HOME, noUncheckedIndexedAccess enabled in tsconfig. - Added Bun test suite (34 tests across resolveConfig, loadConfigFile, editConfig). - scripts/dev-setup.sh made POSIX-portable.	2026-06-17 22:20:59 -05:00
nokeo08	10dcc1791a	Add -e/--edit flag: open config file in $EDITOR New module src/editor.ts handles the flag end-to-end: - editorCommand(editor, path) returns the sh -c argv that lets the shell tokenize multi-word $EDITOR values like 'code --wait'. Extracted so editor.test.ts can verify construction without actually launching an editor. - editConfig(path) checks $EDITOR is set, checks the target file exists, spawns 'sh -c <editor> "$@" -- <path>' with stdio inherited, and exits with the editor's status code. Refuses (CliError -> exit 2) when: - $EDITOR is unset or empty. - The target config file doesn't exist. (Same recovery hint as elsewhere: 'run move once or reinstall'.) src/cli.ts adds the flag to the parser and printHelp(). src/move.ts dispatches it after --version and before config-load. Resolution mirrors the loader: --config <path> wins, else defaultConfigPath(). 8 new tests in src/editor.test.ts cover the pure helper and both refusal paths; the spawn success path is verified via manual 'EDITOR=true move -e' (would otherwise kill the test process). README Usage block, Configuration section (new Editing subsection), and Files table all updated to match.	2026-06-17 22:20:27 -05:00
nokeo08	cc7a487aca	Lazy-import keeper.ts so --help and --version skip nut.js load keeper.ts statically imports @nut-tree-fork/nut-js, which dlopens a sizeable native .node binary. That load dominated cold-start: ~1.2s for 'move --version' immediately after install, vs ~125ms warm. For a flag that just prints a string, that's all overhead. Change: dynamic 'await import("./keeper.ts")' placed after the --help and --version short-circuits. The dynamic import is wrapped in try/catch so import-time failures (e.g., missing native binary, unsupported architecture) route through the same failRuntime() path as anything thrown by the loop. Expected cold start for --help and --version drops to ~50-150ms (Bun + reading a handful of small files, no native module load). move with no flags pays the same load cost as today. tsc --noEmit and the test suite remain clean.	2026-06-17 21:57:42 -05:00
nokeo08	10172f11b0	Bump package.json to 1.1.1 to match next release tag The CLI reads its version string from package.json at runtime, so 'move --version' was printing 1.0.0 even after the v1.1.0 tag landed. Bumping the manifest here so v1.1.1 (carrying the tests/ move and the TS LSP fix) ships with matching output: $ move --version move 1.1.1 Discipline going forward: bump package.json BEFORE creating a tag.	2026-06-17 21:45:00 -05:00
nokeo08	add4a2d60c	tsconfig: explicit 'types': ['bun'] for VS Code LSP bun:test types live in 'bun-types', which is pulled in transitively by @types/bun via a /// <reference types="bun-types" /> directive. bunx tsc finds this via auto-discovery, but VS Code's TS Language Server doesn't always honor auto-discovered @types/* packages under moduleResolution: bundler, so it shows a phantom 'Cannot find module bun:test' error in the editor. Adding 'types': ['bun'] to compilerOptions makes the inclusion explicit and matches what 'bun init' generates for new projects. tsc still passes; the bun test suite still passes; the editor LSP now resolves bun:test correctly.	2026-06-17 21:15:41 -05:00
nokeo08	fec35a2333	Move tests out of src/ into a top-level tests/ directory src/ now contains only source code; tests live alongside it under tests/. Bun's test runner discovers '*/.test.ts' so no test-runner config change is needed. Changes: - tests/config.test.ts (was src/config.test.ts) - tests/configFile.test.ts (was src/configFile.test.ts) - Imports updated: ./config.ts -> ../src/config.ts (likewise for configFile.ts and errors.ts). - tsconfig.json include adds 'tests/*/.ts' so tsc type-checks the test files too. All 25 tests still pass; tsc clean.	2026-06-17 21:05:20 -05:00
nokeo08	9617758d8b	Enable noUncheckedIndexedAccess in tsconfig Tighter type-checking: array indexing and dynamic property access now return T \| undefined rather than T. Catches bugs where code assumes a key exists without checking. No code changes were needed — the existing modules already either: - cast through Record<string, unknown> (configFile.ts), where access is already 'unknown'; - cast values from parseArgs to '... \| undefined' (cli.ts), already nullable; or - use static, statically-known fields (Config, ConfigOverrides, DEFAULT_CONFIG). tsc --noEmit remains clean. The full test suite still passes.	2026-06-17 16:35:33 -05:00
nokeo08	94d963d8ef	Make scripts/dev-setup.sh POSIX-portable The contributor bootstrap script was bash-only ('#!/usr/bin/env bash', 'set -euo pipefail', '[[ ... == ... ]]') while install.sh and uninstall.sh are POSIX sh. Consistency lines them up: - shebang -> '#!/usr/bin/env sh' - 'set -euo pipefail' -> 'set -eu' (pipefail isn't POSIX; not needed here either, no risky pipelines in this script) - '[[ ... == ... ]]' -> '[ ... = ... ]' Also added a 'bun run test' hint to the post-install workflow note now that there's a test suite to run.	2026-06-17 16:35:04 -05:00
nokeo08	1a857de5ed	Add Bun tests for resolveConfig and loadConfigFile Two new test files exercise the layered config resolver and the JSON config-file loader: src/config.test.ts 25 cases: - resolveConfig precedence (CLI > file > default) per field - seconds-to-ms conversion at the resolver boundary - verbose precedence across all four cells - defaultConfigPath: XDG honored, HOME fallback, empty-as-unset, throws CliError when both are missing src/configFile.test.ts 11 cases: - valid file -> overrides, with undefined for unspecified keys - missing explicit path throws - malformed JSON / non-object root throws with file path - unknown key / wrong type / non-positive number all throw with the offending key named - default path missing -> null (silent default) Runs via 'bun test' (or 'bun run test', now wired in package.json). All 25 tests pass on the current codebase.	2026-06-17 16:34:27 -05:00
nokeo08	5af253283e	Introduce failRuntime() to mirror failUser() in move.ts The two stderr-fatal paths used to be asymmetric: failUser() is a named helper with 'move:' prefix and a 'Try --help' hint, while the runKeeper catch was an inline 'console.error("Error:", err)' + process.exit(1). failRuntime() now sits next to failUser(), so the entry-point reads as 'one of two well-named fatal paths.' It also prefers err.stack when available, giving better diagnostics for nut.js / Accessibility-permission failures than the previous formatter. Same observable behavior on the success path; failure messages on the runtime path are now more debuggable.	2026-06-17 16:32:29 -05:00
nokeo08	7120c06bbe	Introduce named Logger interface in keeper.ts Replaces 'ReturnType<typeof makeLogger>' with a small named interface so simulateActivity's signature reads as (config, log: Logger) instead of a type-derivation chain. Also makes it cleaner to substitute a mock logger if simulateActivity is ever unit-tested. No behavior change.	2026-06-17 16:24:56 -05:00
nokeo08	d5656efe5b	Move 'mouse.config.autoDelayMs = 0' from module-load to runKeeper The assignment used to run at import time, mutating the shared nut.js singleton the second anything imported keeper.ts. Moved into the top of runKeeper(), where the only caller actually needs it. Same observable behavior — runKeeper is called exactly once per process — but keeper.ts is now import-side-effect-free, which makes it straightforward to import for tests or future tooling without touching global mouse state.	2026-06-17 16:24:24 -05:00
nokeo08	8eac51cd45	Extract CliError into src/errors.ts CliError used to live in cli.ts and was imported by configFile.ts purely to grab a one-line class — the dependency arrow said 'config-file loader depends on the CLI parser' when really it just needed a shared error type. Moving CliError to its own errors.ts module flattens the graph: errors.ts (no internal deps) \| +-- cli.ts +-- configFile.ts +-- config.ts (will use it in the next commit) cli.ts re-exports CliError for any consumer that prefers to keep importing it from there; the canonical home is now errors.ts.	2026-06-17 16:22:33 -05:00
nokeo08	7714a6ad1a	Seed default config on install; share defaults JSON with runtime The defaults now live in a single file, scripts/config.default.json: - src/config.ts imports it via 'with { type: "json" }' and derives DEFAULT_CONFIG (with seconds->ms conversion at the boundary), so the CLI help text always matches what the seeded user config contains. - scripts/install.sh copies the same file to $XDG_CONFIG_HOME/move/config.json only if no file is already there. Existing configs (yours or from a previous install) are never overwritten. - scripts/uninstall.sh does not touch the user config file at all, following the strict Unix convention. It does print a one-line notice pointing at the path so the user can rm -rf the dir themselves if they want a fully-clean removal. - tsconfig.json gains resolveJsonModule:true so tsc accepts the JSON import. - A small runtime assertion in src/config.ts (assertSeedShape) fails loudly if the seed file is missing keys or has wrong types. - README Configuration section documents the seed behavior; Uninstall section documents the leave-config-behind policy with the rm-it- yourself command; Files table gains scripts/config.default.json.	2026-06-17 13:13:49 -05:00
nokeo08	940113019d	Move verbose into Config; drop resolveVerbose Verbose was awkwardly a separate runKeeper argument with a separate resolveVerbose helper, even though it's just another tunable on the same precedence ladder as the numeric fields. This commit collapses it. Changes: - Config gains 'readonly verbose: boolean'. DEFAULT_CONFIG sets it to false. - resolveConfig now returns the full Config including verbose. Verbose layers with the same 'first defined value wins' precedence as the numeric fields. - resolveVerbose is gone. - ParsedCliArgs.verbose becomes boolean \| undefined: undefined when -V was not passed, true when it was. parseCliArgs maps accordingly. This lets the layered resolver treat verbose uniformly. - runKeeper takes a single Config arg. The internal logger reads from config.verbose at the top of runKeeper. - move.ts no longer plumbs verbose separately; the single resolved Config drives everything. - README How-it-works and Files-table entries updated to match. Behavior verified for all five verbose-precedence cases (no file/no flag, no file/-V, file:true/no flag, file:false/-V, file:false/no flag) and config-error scenarios remain intact.	2026-06-17 12:45:46 -05:00
nokeo08	ccc136f727	Sync README Usage block with current --help The static usage example in README.md was added in milestone 1 and hand-maintained. When -C/--config landed in the JSON-config-file commit, printHelp() was updated but this block wasn't. This commit brings them back in sync and adds the precedence line.	2026-06-17 12:42:37 -05:00
nokeo08	df9305c6ac	Add JSON config file support (XDG-respecting) End users can now set defaults in a config file at: ${XDG_CONFIG_HOME:-$HOME/.config}/move/config.json CLI flags continue to win when both are set: CLI flags > config file > built-in defaults Schema mirrors the CLI flag names and units. Loader is strict: unknown keys, wrong types, and non-positive numerics are rejected with a clear message naming the file and key, and the process exits 2. Changes: - New src/configFile.ts: existence-aware loader + strict schema validation. Throws CliError; the entry point converts those to exit 2. - src/config.ts: ConfigOverrides gains 'verbose'; resolveConfig takes both file and CLI override layers; new defaultConfigPath() honors XDG_CONFIG_HOME; new resolveVerbose() layers verbose with the presence-only-CLI semantics documented. - src/cli.ts: -C/--config <path> flag. printHelp prints the default config path and the precedence rule. - src/move.ts: loads the config file (default XDG path or --config), passes both override layers into resolveConfig, resolves verbose separately, exits 2 on any validation failure. - README: new Configuration section with path, precedence, example, validation rules, and the verbose CLI-can't-turn-off limitation. Files table gains src/configFile.ts.	2026-06-17 12:27:50 -05:00
nokeo08	c9645b374c	Move installer scripts into scripts/ directory - install.sh, uninstall.sh, dev-setup.sh now live under scripts/. - dev-setup.sh's 'cd $(dirname $0)' updated to '.../..' so it lands at the repo root regardless of CWD. - README install/uninstall curl URLs now reference scripts/<name>.sh. - README contributor section and Files table updated to match. Behavior is unchanged. The curl one-liner URL changes from .../master/install.sh to .../master/scripts/install.sh; users following the pre-v1.0.2 README will get a 404 from the old URL.	2026-06-17 12:17:32 -05:00
nokeo08	b43d5aad2d	Add curl-pipe installer, uninstaller, and contributor bootstrap End-user installation collapses to a single command: curl -fsSL https://gitea.cahlen.com/nokeo08/Move/raw/branch/master/install.sh \| sh Changes: - install.sh rewritten as a POSIX sh, curl-pipeable end-user installer. Honors XDG_DATA_HOME and XDG_BIN_HOME (de facto). Idempotent via a version-marker file at $INSTALL_DIR/.installed-version; MOVE_FORCE=1 overrides. Hard-fails if Bun is missing (no auto-install). Includes a safety guard refusing rm -rf on too-broad install dirs. - uninstall.sh added; same curl-pipe pattern, shared XDG path resolution, leaves Bun alone. - dev-setup.sh added (= the previous install.sh content, retitled for contributors and pointing at bun run start / bun link / install.sh). - README updated: curl one-liner Install section, XDG behavior tables, new Uninstall section, new 'For contributors' section, Files table rows for all three scripts.	2026-06-17 11:55:03 -05:00
nokeo08	081f94088d	Remove distribution plan (resolved) The plan is being implemented in the following commit. The working-notes document has served its purpose and is removed to keep master focused on shipping artifacts.	2026-06-17 11:48:36 -05:00
