Building and testing

Build, run, and test SubMiner from source. Architecture and workflow rules live in the repo's internal docs, starting at docs/README.md. Module boundaries and layering rules are in docs/architecture/README.md. The lane-by-lane test guide is docs/workflow/verification.md.

Prerequisites

• Bun, at the version pinned in package.json
• A system lua interpreter for the mpv plugin tests (bun run test:launcher, bun run test:env)
• macOS only: bun run build compiles a Swift window helper. Set SUBMINER_SKIP_MACOS_HELPER_BUILD=1 to skip it.

Setup

git clone --recurse-submodules https://github.com/ksyasuda/SubMiner.git
cd SubMiner
make deps

make deps initializes submodules and installs dependencies for the root, stats/, and vendor/texthooker-ui. The Yomitan submodule installs its own dependencies during bun run build.

Build

bun run build               # app build, including bundled Yomitan from vendor/subminer-yomitan
bun run build:appimage      # Linux AppImage
bun run build:mac           # macOS DMG + ZIP (signed)
bun run build:mac:unsigned  # macOS DMG + ZIP (unsigned)
bun run build:win           # Windows NSIS installer + ZIP
make build-launcher         # launcher only, output: dist/launcher/subminer

The launcher source is launcher/*.ts. dist/launcher/subminer is generated, so never edit it by hand. The repo-root ./subminer is a stale path and verification rejects it. make install-linux and make install-macos copy from dist/launcher/subminer. To check the launcher build:

make build-launcher
dist/launcher/subminer --help >/dev/null
bash scripts/verify-generated-launcher.sh

Run locally

bun run dev                                  # build, then launch with --start --dev
make dev-watch                               # watch TS + renderer and relaunch Electron
make dev-watch-macos                         # same, forcing --backend macos
electron . --start --dev --log-level debug   # verbose launch of an existing build
electron . --background                      # tray/background mode

To test through the mpv plugin without exporting SUBMINER_BINARY_PATH each time, point mpv.subminerBinaryPath in your config at the dev script. The launcher passes it to the plugin at runtime:

{
  "mpv": {
    "subminerBinaryPath": "/absolute/path/to/SubMiner/scripts/subminer-dev.sh"
  }
}

Test

Run the handoff gate before submitting substantial changes:

bun run typecheck
bun run test:fast
bun run test:env
bun run build
bun run test:smoke:dist

For smaller changes, start with the cheapest lane that covers what you touched:

Command	Covers
bun run test / test:fast	All src/** tests, launcher unit tests, and scripts/** tests
bun run test:config	Config schema, defaults, and config.example.jsonc generation
bun run test:launcher	Launcher tests plus the Lua plugin tests
bun run test:env	Launcher e2e smoke, Lua plugin tests, SQLite immersion tests from source
bun run test:scripts	Build and release scripts under scripts/**
bun run test:stats	Stats dashboard UI under stats/src/**
bun run test:runtime:compat	Compiled-runtime smoke against dist/ (run bun run build first)
bun run test:immersion:sqlite	Compiles, then runs the SQLite-backed immersion tracker tests
bun run test:subtitle	alass/ffsubsync subtitle sync
bun run test:docs:kb	Internal docs, AGENTS.md, and repo skills

Lane membership is defined in scripts/test-lanes.ts and discovered by directory, so a new test file joins its lane automatically. Do not hand-list test files in package.json. scripts/run-test-lane.mjs runs each file in its own bun test process, so a hanging test cannot take down the rest of the lane. Pass --jobs N to parallelize or --single-process to share one process while debugging.

Launcher smoke artifacts go to .tmp/launcher-smoke. CI uploads them when the smoke step fails.

Format

make pretty               # format the maintained source and stats files
bun run format:check:src  # check the same set without writing

bun run format runs Prettier over the whole repo. Use it only when you mean to.

Config generation

bun run electron . --generate-config   # write a default config to ~/.config/SubMiner/config.jsonc (%APPDATA%\SubMiner\config.jsonc on Windows)
bun run generate:config-example        # regenerate config.example.jsonc from the defaults

make generate-config and make generate-example-config wrap the same commands.

Config definitions are split by domain under src/config/definitions/:

• defaults: defaults-*.ts
• option metadata: options-*.ts
• generated template sections and comments: template-sections.ts

src/config/definitions.ts composes them into the public API (DEFAULT_CONFIG, registries, template export). A new key also needs a resolver entry under src/config/resolve/, or the resolved config keeps the default.

Documentation site

The user docs live in docs-site/ (VitePress).

bun --cwd docs-site install
bun run docs:dev      # dev server at http://localhost:5173
bun run docs:test     # docs regression tests (links, pinned strings)
bun run docs:build    # production build into docs-site/.vitepress/dist
bun run docs:preview  # preview the build at http://localhost:4173

Run bun run docs:test and bun run docs:build whenever you change docs-site/.

Production uses the versioned build:

bun run docs:build:versioned

It writes .tmp/docs-versioned-site: the latest stable docs at / with a generated /versions page, and development docs at /main/. Prerelease tags are skipped. Stable archives under /v/<version>/ are built once and stored in R2. Without R2 credentials the build skips archive sync, so a local run only produces / and /main/.

The docs-pages GitHub Actions workflow uploads that output to Cloudflare Pages with Wrangler. Cloudflare's Git-integration builds are disabled on purpose, so do not re-enable them in the dashboard. docs-site/README.md has the full deployment setup.

Contributor notes

• See Architecture for module boundaries and IPC + runtime contracts before adding IPC channels.
• src/core/services/overlay-manager.ts owns overlay window and visibility state.
• In src/main/ modules, pass simple dependencies as inline objects. Add a helper or adapter only when it adapts, validates, or gets reused.
• Packaged Linux desktop launches pass --background through build.linux.executableArgs in package.json.
