Tasks

Backlog and tracking for tiny-pattern-ts. Managed in vscode-todotasks format.

---

Setup:
✔ Establish release CI workflow: post-tag checks + npm publish after release tag push => pi --session 01a06e72-e61e-7327-b3e9-3e11749a523f @high @done (9/11/2026, 12:37:35 AM)
☐ Add gitea release page in CI @high
☐ Split off template into separate package => pi --session 01a07dde-7050-7054-bb36-1606d7eb2bc3 @high
✔ Make the pi-lsp install reproducible @done
    - `.pi/npm/.gitignore` is `*` / `!.gitignore`, so only `.gitignore` is committed; `.pi/npm/package.json` and `package-lock.json` are untracked
    - the README insists `@spences10/pi-lsp` is "pinned to 0.0.46", but the lockfile that pins the transitive tree does not survive a fresh clone
    ✔ Resolved by design, no change: `.pi/settings.json` is the shared committed declaration (`npm:@spences10/pi-lsp@0.0.46`), and `.pi/npm/` is a gitignored install cache pi recreates on a trusted startup (settings.md: trusting a project allows pi to "install missing project packages"). The .gitignore is intentional; the exact pin lives in the committed settings file. README clarified @done
✔ Gate the emit path in `npm run verify` @done
    - `verify = check + test:unit`; `check:tsc` uses the root config (`noEmit: true`), so `tsconfig.build.json` is only exercised by `build`
    - a broken build config (bad `rootDir`, emit-option typo) passes `verify` and only fails in CI
    ✔ Confirmed no change: `verify` is the local quick source-correctness check; the emit path is gated by CI's `build` job (`npm run build`), so adding `build` locally only adds inner-loop friction @done
☐ Fix `.ts` extensions in emitted `.d.ts`
    - emitted JS rewrites `./pattern.ts` → `./pattern.js`, but `dist/*.d.ts` still imports `"./pattern.ts"` / `"./match.ts"`
    - resolves under TS7, but a portability risk for older resolvers/bundlers; `attw` does not catch it
    ☐ Fix the declaration emit (`.d.ts` post-step) or stop using relative `.ts` in the declaration surface
    ☐ Reconcile the README/CONTRIBUTING claim that `rewriteRelativeImportExtensions` yields "conventional ESM imports"
    ☐ Add a consumer-resolution test to the suite (durable guard; `attw` currently misses it)
☐ Document pi-lsp false-positive diagnostics
    - `lsp_diagnostics` reports TS1295/TS1287 "CommonJS file under `verbatimModuleSyntax`" errors that `check:tsc` never produces — the server is not picking up the repo's `tsconfig.json`
    - AGENTS.md only warns that empty LSP output is inconclusive, not that it can emit false errors
    ☐ Add a line to AGENTS.md: ignore LSP errors that `check:tsc` does not reproduce
    ☐ Or fix the LSP server configuration so it picks up `tsconfig.json`
✔ Run packaging checks in CI `build` @done
    - `publish:publint` / `publish:attw` only run in the tag-triggered `publish` job, so a PR that breaks packaging stays green until release
    ✔ At minimum add `publish:publint` to the `build` job (offline, fast); `attw` needs a pack @done
✔ Publish the exact artifact CI tested @done
    - `publish: needs: build`, then re-runs `npm ci` + `build` from scratch, discarding the tested output
    - tag push pays a double build and the two builds could differ
    ✔ Persist `dist/` as an artifact in `build` and consume it in `publish` @done
✔ Confirm pre-push gate strength @done
    - pre-push runs `npm test` (`check:tsc` + tests), not full `check`; the staged-file oxlint/oxfmt/cspell checks live in pre-commit, whole-project correctness in CI
    ✔ Confirmed intended: pre-push is a local quick check, not a gate — CI on Gitea is the authoritative whole-project gate and checks the pushed commits' content; dirty working-tree files are out of scope by design @done
✔ Clean stale `coverage/` in `npm run clean` @done
    ✔ `npm run clean` only removes `dist`; add `coverage` (both are gitignored but bloat the working tree) @done
✔ Drop redundant `main`/`types` top-level fields @done
    ✔ `exports` is the source of truth; `main`/`types` are redundant (harmless, but publint/ATTW prefer `exports`) @done
✔ Silence the knip `@runwisp/pubv` false positive @done
    - `pubv` is a CLI invoked by `release.sh`, not imported, so knip flags it as an unused devDependency and advisory output stays permanently red
    ✔ Add a knip `ignoreDependencies` entry @done
☐ Resolve sourcemap sources for consumers
    - `dist/*.map` `sources` are `../src/*.ts`, but `src` is not in `files`, so debuggers get missing sources
    ☐ Ship `src`, or disable `sourceMap`/`declarationMap` for the published artifact
✔ Sweep doc/formatter drift before v1.0 @done
    ✔ README says `--experimental-strip-types`; scripts use `--strip-types` @done
    ✔ `.vscode/settings.json` bundles `[markdown]`/`[yaml]` oxfmt formatters separately from `.oxfmtrc.json`'s `ignorePatterns` — align @done
✔ Document branching model @done
    ✔ Describe branching model: when to branch, base branch, naming @done
    ✔ Clarify release workflow: who pushes `main`, CI as post-merge gate, drop PR usage @done (9/8/2026, 2:54:32 PM)
✔ Evaluate connecting the agent to lsp typescript server @done
    - might be more difficult with TS7, since LSP Server has changed from 6
    - but since vscode is running TS7, maybe it is possible to connect to the TS7 LSP server of vscode
    - LSP servers in general?
    - maybe skills?
    → resolved: adopted @spences10/pi-lsp@0.0.46 as a project-local pi extension (`.pi/settings.json`). It auto-detects the repo's TypeScript 7 (no `lib/tsserver.js`) and spawns `tsc --lsp --stdio` — the same tsgo binary VS Code's native-preview uses. Read-only: hover / definition / references / symbols / diagnostics. No skill; skills don't own persistent processes.

✔ Adopt a `setup:` prefix for one-time clone configuration @done
    ✔ Register `use:git-commit-message` as its first member (and retire `use:` — it is in no prefix list) @done
    ✔ Create an umbrella 'setup' task that runs all setup tasks - currently one @done

v1.0:
☐ API surface is stable and fully typed
    ☐ Finalize public exports in `src/index.ts`
    ☐ Document all exported types and functions
    ☐ Add JSDoc for public APIs
☐ Test coverage meets threshold
    ☐ Achieve 100% branch coverage on `src/pattern.ts`
    ☐ Achieve 100% branch coverage on `src/match.ts`
    ☐ Achieve 100% branch coverage on `src/index.ts`
☐ `dist/` output is clean
    ☐ Verify `.d.ts` declarations match public exports
    ☐ Ensure `.js` files use `.js` extensions (not `.ts`)
    ☐ Test `attw --profile esm-only` passes

Bugs:

Enhancements:

Documentation:
☐ Add usage examples to README.md
☐ Create `examples/` directory with runnable snippets
☐ Add comparison section vs. other TS pattern-matching libs
☐ Write migration guide for users coming from discriminated unions
☐ Create backlog tasks for implementation

Maintenance:
☐ Serve CI coverage over a tiny self-hosted webserver (replace the zip artifact) @low
    ☐ Add a minimal dir-listing webserver to the gitea docker setup (e.g. caddy `file_server browse` reusing the existing reverse proxy, or any single-binary static server, lipanski/docker-static-website)
    ☐ CI writes each run's `coverage/` into a shared volume keyed by project + tag (e.g. `/coverage/tiny-pattern-ts/<tag>/`)
    ☐ Browse to `…/coverage/<repo>/<tag>/index.html` in the browser; drop the `actions/upload-artifact` coverage step in favour of the shared-dir layout
    → design: no deploy step in CI; the webserver just exposes the shared directory (decided over Gitea Pages / Codecov — neither confirmed available/ wanted)
