@awacloud/tool-fw-codegen

Code-generation tools for @awacloud/fw-shaped packages: the registry generator (the module-name → factory instance-type map that powers @awacloud/fw/typed), the deps one-shot injector (fills the deps: [...] companion field on modules declaring string-form dependencies), and the audit read-only report (classifies each module's factory @returns annotation into LOSSY/INFER/INLINE/TYPED buckets). Generalised to any fw-shaped package via a --pkg / --src seam.

The shared fw-module substrate (scanAll, relativeImport, …) is consumed from @awacloud/tool-fw-bundler/modlib (a devDep). No scan-modules.js is re-copied into this package.

Consumption shape

Autonomous — standalone bin. This package ships its own fw-codegen executable (bin/fw-codegen.ts, a thin delegate to src/index.ts — no argument parsing duplicated), so it runs directly once installed:

bunx fw-codegen registry --pkg packages/front/fw --check

Installation

npm install --save-dev @awacloud/tool-fw-codegen

Runs under Bun (the bin is TypeScript executed by Bun).

Quick Start

# Regenerate a package's typed-runtime registry (defaults to the current dir)
bunx fw-codegen registry --pkg packages/front/fw

# Verify the registry is up to date (exit 1 if stale)
bunx fw-codegen registry --pkg packages/front/fw --check

# Inject the `deps: [...]` companion field into a package's modules
bunx fw-codegen deps --pkg packages/front/office/pdf

# Report the planned deps edits without writing
bunx fw-codegen deps --pkg packages/front/office/pdf --dry-run

# Exclude an extra subtree from the deps scan (repeatable; unioned with the
# default ignore of generated `src/bundles/prebuilt/**`)
bunx fw-codegen deps --pkg packages/front/office/md --ignore "legacy/**"

# Audit a package's factory @returns annotations (read-only report)
bunx fw-codegen audit --pkg packages/front/fw

# Only print the LOSSY/INLINE fix-list sections
bunx fw-codegen audit --pkg packages/front/fw --lossy-only

--pkg <dir> selects the package root (src/, types/, dist/types/ resolve under it). When omitted it defaults to the working directory, so fw's own build scripts — which run at the fw package root — keep working unchanged. deps also accepts --src <dir> to point the scan at a source dir directly, plus --ignore <glob> to exclude subtrees.

From a consumer package (office), deps additionally ignores generated prebuilt bundles by default, resolves dependency names it cannot find locally through four static layers — the descriptor's own package imports, the entry main.js under its fw_require guard, the entry under its pkg_require guard, and one hop into a sibling package reached by a pkg_require namespace spread — and skips (rather than aborts on) a module whose names it cannot resolve. It never imports package code and never emits a private deep path across a package boundary. What it writes is always a real binding: the module name: is aliased to the actual export when the two differ, comments are not mistaken for imports, and an identifier that would not be bound in the resulting file is reported as unresolved instead of written. See docs/README.md § Consumer-package behaviour and § What is written is a real binding.

Direct invocation without the bin is equivalent:

bun node_modules/@awacloud/tool-fw-codegen/src/registry/index.js --pkg packages/front/fw --check
bun node_modules/@awacloud/tool-fw-codegen/src/deps/index.js --pkg packages/front/office/pdf --dry-run
bun node_modules/@awacloud/tool-fw-codegen/src/audit/index.js --pkg packages/front/fw --lossy-only

Structure

src/
  index.ts            CLI dispatch: `registry` | `deps` | `audit`
  registry/
    index.js          types/registry.generated.d.ts emitter (renderRegistry, runCli)
  deps/
    index.js          the deps: [...] one-shot injector (planDeps, runDeps, runCli)
  audit/
    index.js          factory @returns LOSSY/INFER/INLINE/TYPED report (computeAudit, renderAudit, runCli)
tests/                golden (registry byte, audit byte) / equivalence (deps semantic) + idempotence
  __fixtures__/
    mini-fw/          fw-shaped package for the registry write path
    deps-src/         a module missing `deps` — exercises the injector
    deps-ignore/      real modules + generated prebuilt bundles — exercises the ignore filter
    deps-fw/          an office-shaped consumer (main.js + fw_require) — exercises fw resolution
    deps-workspace/   a whole fixture workspace (root + consumer + sibling) — exercises pkg_require
    deps-noworkspace/ a manifest without `workspaces` — pins the walk-up behaviour
    deps-binding/     name ≠ export, an alias that would shadow, a JSDoc import — exercises the emit guard
    audit-src/        a module tree spanning LOSSY/INFER/INLINE/TYPED — exercises the auditor

The shared substrate lives in the sibling package:

import { scanAll, relativeImport } from '@awacloud/tool-fw-bundler/modlib';

Build

Not applicable — the tool is executed directly by Bun (no build step). The registry / deps / audit subcommands ARE the codegen machinery for downstream fw-shaped packages.

Exit codes

Tests

bun test tools/fw-codegen/

The suite byte-compares registry output against the real fw package's committed registry.generated.d.ts (the file fw's own types:registry:check validates), proves byte-idempotence, drives the deps injector on a fixture with a normalized (semantic) equivalence check on the injected imports + deps literal, and byte-compares audit's rendered report against fw's own tools/types/audit script's stdout (the verbatim-port oracle). See docs/README.md for the frozen call contract.
