Add a `compat` job that type-checks the whole suite and a consumer fixture
against the minimum supported TypeScript (5.9), reusing the `dist/` artifact
`build` produced and gating `publish`. The compiler is resolved by npx, so it
never enters `devDependencies` or the local `check`/`verify` loop.
The fixture imports the package by name, resolving the emitted declarations
through the `exports` map; `expectTypeOf` / `.not.toBeAny()` make it reject an
`any`-typed declaration, which a bare compile would accept.
Correct the README consumer floor from >= 5.0 to >= 5.9 (set by `type-fest`)
and drop the `node10` resolution claim, which the exports-only entry never
satisfied.
Bump every direct dependency to the latest registry version: cspell
10.3.5, oxfmt 0.71.0, oxlint 1.86.0, oxlint-tsgolint 7.0.2003,
@types/node 26.6.3, the LSP protocol types 3.18.4 and 85 transitive
entries. oxfmt is the only range widened (^0.70.0 -> ^0.71.0), because
0.x minors are breaking under semver and `npm update` stops at the
range; the rest moved within their existing ranges.
`npm run maintain:outdated` is clean and `npm run verify` is green with
no rule or format fallout. `maintain:knip` reports one configuration
hint — the redundant `src/index.ts` entry pattern in knip.json — but
knip did not move, so the hint predates this bump and stays advisory.
The README collapsed to API-only prose once the old match/P surface was
dropped. Rebuild its entry-point shape: a quick-start Synopsis walked through
a Contact union, a dedicated Installation section, and a real-world Examples
section (primitive-union dispatch, a fallback, a property union narrowed by
the tagged-union matcher, and the widening variant).
Set the tagline and Description to the library's identity — exhaustive,
type-safe pattern matching for TypeScript — and state the goal Moose-style:
type-safe pattern matching with a lean syntax, accomplished by exhaustive
branches and typed per-branch handler parameters, backed by autocomplete and
a tiny footprint. Drop the F#-style framing and the stale "matches method is
a type guard" and "(not regex)" copy from the README, AGENTS.md and the
package.json description. Every fence is a doc-test, so the examples cannot
drift from the API.
Drop the `pretest:ci` lifecycle hook and call `create:doc-tests` from the
`build` job before `test:ci`. The hook hid the step from the job log and
made `test:ci` behave differently under npm than when run directly.
An example that exercises a line no hand-written test reaches would let
the `--100` gate pass on documentation alone. Node has no file-level
exclusion, and c8's `--exclude` only filters the report, so run the two
in separate processes: `test:coverage` runs c8 over the tracked tests
only (`git ls-files`, which skips the untracked generated files), and
`test:doc` runs the generated examples without c8. `test:ci` chains
them.
Every `ts`-tagged fence in README.md / CONTRIBUTING.md now becomes an
executed `node:test` case in a gitignored generated file, so a
documented example cannot drift from the API. The generator hoists and
merges the leading imports, rewrites the library specifier to the
`#test-tiny-pattern-ts` alias, and rejects a fence with no describing
paragraph or one that re-imports a prelude module.
CI regenerates via `pretest:ci`; `create:doc-tests` runs the generator,
formats, then typechecks the output against a scoped tsconfig that
relaxes `noUnusedLocals`. c8's default excludes already omit the
generated `*.test.ts`, so `test:ci` is unchanged.
test:ci now runs c8 with --all --include "src/**/*.ts" --100, so the
build job fails when any runtime file under src/ is untested. --all is
what makes the gate non-vacuous: without it c8 counts only the files the
suite happened to load, and a new untested module stays invisible.
Add src/index.test.ts to load the public barrel, which was previously
never imported at runtime and so read as 0% under --all. matcher-shared.ts
is types-only (an empty runtime image) and carries a file-level c8 ignore
with the reason.
Why 100% and the rejected alternatives: development/ci.md § Coverage
threshold.
Bump every direct dependency to the latest registry version: cspell
10.3.3, knip 6.38.0, oxfmt 0.70.0, oxlint 1.85.0, oxlint-tsgolint
7.0.2002 and type-fest 5.10.0, plus their transitive updates. oxfmt is
the only range widened (^0.68.0 -> ^0.70.0); the rest moved within
their existing semver ranges.
`npm run maintain:outdated` is now clean and `npm run verify` is green
with no rule or format fallout. `maintain:knip` still reports the
pre-existing `src/index.ts` false positive (dist-only `exports`), which
predates this bump.
The autocomplete helper drives tsc --lsp --stdio; vscode-languageserver-protocol
supplies the transport (re-exported vscode-jsonrpc/node) and the typed LSP
requests, replacing the hand-rolled JSON-RPC client. Record the choice and
the rejected alternatives in tooling.md.
src/util/__tests__/ holds shared test helpers, reached from anywhere
in the source tree as `#test-utils/<name>.ts` through
package.json#imports. A bare `~/…` is not a valid imports key — Node
requires `#` — and a direction-free specifier keeps
import/no-relative-parent-imports from ever firing. The `__tests__`
folder name is the pattern tsconfig.build.json already excludes, so
helpers can never ship. Lint scoping: import/no-nodejs-modules off for
the folder (the probe spawns a language server) and
typescript/promise-function-async off to match its promise-returning
style. The LSP probe moves in from scripts/; a smoke test pins the
specifier's resolution and typing without starting a server.
Curried matchers over string|number literal unions in four variants
(exhaustive/partial x strict/widened return inference), per the header
matrix in src/primitive.ts.
- Adds type-fest for Simplify/ValueOf.
- Deliberate oxlint escape hatches (as any dispatch) until a cast-free
formulation lands; see the file comments.
DefinitelyTyped keeps the @types/node latest dist-tag on the LTS line,
so check-outdated compared the current-line types against a lower
version: a permanent "reverted" flag, scan exit 1, zero signal. Ignored
by package name; --types filtering and a version-scoped pin rejected
(rationale in development/tooling.md).
@types/node to ^26.6.1 and cspell to ^10.3.2 — the only packages
check-outdated found behind the registry, both bumps within the existing
semver ranges. cspell 10.3.2 drops its transitive
fast-json-stable-stringify. npm run verify is green with no rule or
format fallout. maintain:outdated still flags @types/node as "reverted"
because DefinitelyTyped's latest dist-tag stays on the 22.x LTS series;
known false positive, advisory scan only.
Latest releases of the two oxc tools; both minor bumps within 0.x/1.x
semver ranges. check-outdated now reports zero outdated dependencies
and npm run verify passes with no rule or format fallout.
The merge half of the branching model was still prose, so it drifted per
session. create:finish mirrors create:branch: it asserts the merge-side
preconditions, fast-forwards a stale main (divergence is refused), merges
--no-ff, runs npm run verify, and deletes the branch only when green. The
push stays with create:release so the merge is reviewable first.
Add scripts/precompress.ts, a dependency-free Node 26 tool that writes
.br/.gz/.zst sidecars next to every text asset and keeps the originals, so
static-web-server can serve the variant matching Accept-Encoding and fall
back to the original. The coverage publish step runs it on the copied report.
Wire scripts/*.ts into the toolchain: type-check (tsconfig include), lint and
fix (oxlint paths), knip entry (CI invokes the file rather than importing it),
and a narrow .oxlintrc override allowing node:* imports in Node CLI scripts.
tsc does not prune orphaned emit output, so dropping declarationMap left
stale *.d.ts.map files in dist/ until a manual clean. A prebuild hook now
empties dist/ first, keeping the build reproducible. It deliberately leaves
coverage/ alone, since the manual `clean` resets both.
The node -e rmSync one-liner was carried over from the build-tool
switch and only existed for cross-platform shell safety. The repo is
POSIX-only (sh scripts, Node 26, Linux CI), so rm -rf is simpler and
consistent with the rest of the tooling.
exports already declares types + import for the root entry, so the
top-level main/types pair was duplicate metadata. publint and attw stay
green with exports alone, verified against a packed consumer install.
Introduce a setup: prefix for one-time clone configuration (mutates the
local environment, never a hook or CI step) with setup as its umbrella
aggregator. Move use:git-commit-message to setup:git-commit-message as
its first member, retiring use: — the undocumented prefix tracked in the
backlog. Update both CONTRIBUTING.md prefix lists, the bare-command
inventory, and the stale use: reference in branch.sh.
`branch` and `release` were bare commands, but bare in this repo means
"how you invoke a tier" or "runs one tool" — neither fits a command that
opens or closes a unit of work. They get their own prefix now, since a
prefix is how this repo records _when_ a script runs.
`create:` because both members genuinely create something (a branch, a
release) and it is a plain verb rather than VCS slang. No bare `create`
aggregator: running "all the workflows" describes nothing anyone wants,
and `publish:*` already precedents a prefix without one.
The rule "reuse an existing prefix, never invent one" now says what it
actually means: a new prefix is allowed when the scripts belong in the
pipeline, provided it enters both lists in the same commit as its first
member. That is the lesson from `use:`, which is referenced by prose yet
in none of the lists — already tracked in backlog.tasks.
The bare-command sentence shrinks to `build`, `clean`, `verify`.
The branching model assumed a clean, current `main` and a green baseline
before any edit, but both were prose, and prose nobody checks silently
becomes a suggestion. `npm run branch -- <prefix>/<desc>` asserts the
precondition and only then creates the branch, so a later failure is
attributable to the change that caused it.
Checks run cheap-first (`--porcelain` deliberately catches untracked
files, which would otherwise ride onto the new branch) and the suite
runs last, so an ineligible tree never pays for it. `main`'s remote is
derived from its upstream rather than hardcoded: this repo has both
`origin` and `origin_https`, and `main` tracks the latter, so a
`git fetch origin main` currency check would compare against a ref that
is never updated here. The baseline runs after switching to `main`, so a
red `main` restores the starting branch instead of stranding the caller
on it.
The prefix stays a judgment call: the script validates it against the
documented vocabulary instead of inferring it.
Prose kept as index only — AGENTS.md points agents at the command from
the task workflow, CONTRIBUTING.md owns the model and the bare-script
tier (dropping its stale hardcoded count of "two" conveniences).
Release front-door: pubv runs preflight + the interactive semver
heuristic and graduates CHANGELOG.md [Unreleased] -> dated; npm version
syncs package.json + lockfile; git commit --amend folds them into
pubv's single release commit; the tag is created AFTER the amend so it
marks the exact commit on main that gets published; then push. Tags are
v-less (--tag-prefix=none) to match the changelog compare refs.
@runwisp/pubv added as a devDependency. The short "how we got here /
what was rejected" note lives as a comment atop the script; the docs/
exploration was removed as too much to read.
The repository.url shipped github.com/tmueller/... but the real remote
is gitea.e1nsnull.de/tmu/..., so the npm page's Repository link 404'd.
Add homepage + bugs, fix the URL, and rename the CONTRIBUTING "GitHub"
reference to the forge. Delete .npmignore: when a package.json `files`
allowlist is present npm never consults .npmignore, so it was dead
weight that would only drift. Add "gitea" to the cspell dictionary.
Copying the template into .git/COMMIT_EDITMSG has no lasting
effect: git pre-fills that file from the commit.template config,
so the script registered nothing and the template never appeared.
Use git's own mechanism, which is what git reads for every
interactive commit.
Name, prefix and call site are unchanged, so README's setup
bullet stays correct; only the sentence describing the old copy
in CONTRIBUTING needed rewording. Note the config holds a path
relative to the working directory, so it applies to commits made
from the repo root.
oxlint, oxfmt and oxlint-tsgolint each declare their own platform
bindings as optionalDependencies gated by os/cpu, so npm already
installs exactly the one matching the host. Listing all 20 at the
root duplicated that: the lockfile diff shows no package added or
removed, only re-tagged as a dev transitive.
The root list was also the sole reason maintain:outdated carried a
20-package --ignore-packages hack, since check-outdated scans root
deps. Without it the script is one flag and reports clean.
Verified on the pinned node 26: fresh `npm ci` in sync, `npm run
verify` green, type-aware oxlint still fires (no-floating-promises),
and `npm install --os/--cpu` dry-runs resolve the darwin-arm64 and
win32-x64 bindings from the lockfile.
