Add configuration service: JSONC parsing, OS paths, layered settings, file watching - #49
Merged
Conversation
… file watching Implements Task 1.10 (Issue #11, Req 9, design.md §11): the config service backing tecode.config. - host/paths.ts: OS-dependent config-directory resolution (POSIX ~/.config/tecode/, Windows %APPDATA%\tecode\), confined to this module so no other code branches on process.platform. Derives the user settings.json / keybindings.json paths and a workspace .tecode/settings.json path. - config/jsonc.ts: a small hand-written, never-throwing JSONC parser (no dependency, per design.md §11/§15) that strips // and block comments plus trailing commas while tracking string-literal state (escaped quotes included), then delegates to JSON.parse. Failures report a message with a best-effort 1-based line/column; Bun's JSON.parse carries no position info, so that path documents and falls back to line 1, column 1 while still attempting to recover a V8-style "position N" when present. - config/service.ts: createConfigService(deps) layers defaults (from registerConfiguration's ConfigurationContribution schemas) under user settings.json under workspace .tecode/settings.json (later wins), exposes get()/onDidChange (ConfigChangeEvent with a dot-boundary-aware affectsConfiguration), watches all three files plus keybindings.json via an injectable fs seam (defaulting to node:fs/promises + node:fs.watch, guarded against watching a missing file), diffs merged keys structurally so a reload that reproduces identical values fires no event, keeps the last-good layer on a parse error while reporting through the log/sink, and best-effort validates value types against registered schemas (mismatch => warning, still served). Initialization returns synchronously and exposes a `ready` promise rather than making the factory async, matching every other createX() in core. - Wires both modules into their barrels, replacing the CONFIG_PLACEHOLDER export. Tests: 50 new (21 jsonc, 7 paths, 22 service — including a fake-fs suite covering layering, defaults, live reload, affectsConfiguration boundary cases, parse-error resilience, and type-mismatch warnings, plus one real-filesystem watch integration test). Full suite: 300 pass, 0 fail. `bun run lint` and `tsc --noEmit` clean across every package.

519-542: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win同一キーの多重登録で dispose が他の登録を消します。
複数の contribution が同じキーを登録した場合、
schemasとdefaultsLayerは後勝ちで上書きされます。片方を dispose すると、もう一方が登録した default とスキーマも削除されます。MVP として許容するなら、その方針を TSDoc に明記してください。厳密にするなら、キー毎に登録スタックを保持し、dispose 時に直前の登録へ戻す実装が必要です。

fs.watchは 1 回の保存で複数イベントを発火することがあります。エディタが書き込み途中のファイルを読むと、解析エラーになりsinkへユーザー向けエラーが通知されます。直列化は正しく実装されていますが、イベント合流の抑制はありません。数十ミリ秒のデバウンスをスケジューラに追加すると、重複読み取りと一時的な誤ったエラー通知の両方を減らせます。

298-310: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winスキーマ登録後にも既存レイヤを再検証してください。
validateLayerTypesはレイヤ読み込み時にのみ実行されます。registerConfigurationが初期ロード完了後に呼ばれると、すでに読み込み済みの user / workspace レイヤは検証されません。その結果、型不一致の警告が出ません。
service.test.tsの型検証テストはawait service.readyより前に登録しているため通ります。これはマイクロタスク順序への依存です。実ホストでは拡張のスキーマ登録が初期ロード後になる可能性があります。♻️ 提案する変更

… view
Two review findings:
- An FSWatcher is an EventEmitter: an "error" event with no listener is
rethrown as an uncaught exception and would kill the whole process on
an asynchronous watcher failure (file deleted, OS watch limit, stale
handle). The fs seam's watch() now takes an onError callback; the node
implementation absorbs the "error" event, closes the dead watcher, and
hands the failure to the service, which logs a warning noting that live
reload for that file stops until restart.
- The merged view was a plain object literal, so get("toString") and
friends returned inherited Object.prototype members for unconfigured
keys. The merged view is now built on a null prototype (initial value
included).
Regression tests cover both: prototype-member lookups return undefined,
and firing a watcher's error callback records a warning without throwing.

Claude-Session: https://claude.ai/code/session_01WELSsojQQL1cTAR5iUUsTK- registerConfiguration revalidates the already-loaded user/workspace layers, so type-mismatch warnings no longer depend on whether a schema registration landed before or after the initial load. - The duplicate-key registration policy (last-write-wins; dispose removes the key outright without restoring an earlier contribution) is recorded as a deliberate MVP trade-off in TSDoc, as is the decision not to debounce watch events (serialized reloads self-heal a mid-write parse error on the burst's final event). - The JSONC error-position regex is anchored to "at position N" so a config file merely containing the words "position 123" cannot skew the reported line/column. - The real-filesystem integration test redirects HOME/APPDATA into its temp dir for the factory call, so it never reads or watches the real user's ~/.config/tecode files.

Implements Task 1.10: the configuration service (Req 2.x, design.md §11/§15/§17), following the CodeRabbit plan on the issue.
What's included
packages/core/src/host/paths.ts(new)~/.config/tecode/on POSIX,%APPDATA%\tecode\on Windows.

Re-exported from the host barrel.packages/core/src/config/jsonc.ts(new)//or,inside a string survives, escaped quotes handled), then delegates toJSON.parse.JSON.parse(JavaScriptCore) carries no position info in its errors — verified empirically — so a position regex is attempted for portability and the fallback is documented.packages/core/src/config/service.ts(new)createConfigService({ log, sink, workspaceRoot?, fs? })— synchronous factory matching every othercreateXin core, exposingready: Promise<void>;get()never blocks.registerConfigurationcollectsConfigurationPropertySchemaentries whosedefaults form the defaults layer; a type-mismatched user value is logged as a warning but still served (MVP best-effort validation).settings.json← workspace.tecode/settings.jsonwith flat dot-separated keys;get<T>(key)resolves from the merged view.node:fs): on change, re-read and re-parse; parse failure keeps the last-good layer and reports the position through the sink without touching the merged view; success rebuilds the view, diffs keys with structural equality (re-parsing identical JSON must not fire), and firesonDidChangeonly on real changes.affectsConfiguration(section)matches exact keys, dot-ancestors, and dot-descendants — never bare-prefix collisions likeeditorX.keybindings.jsonentries are held for the keymap layer (wiring lands in a later task);dispose()closes all watchers.Barrels
