Development

Prerequisites

• Bun

Setup

git clone --recurse-submodules https://github.com/ksyasuda/SubMiner.git
cd SubMiner
# if you cloned without --recurse-submodules:
git submodule update --init --recursive

make deps
# or manually:
bun install
(cd vendor/texthooker-ui && bun install --frozen-lockfile)

Building

# TypeScript compile (fast, for development)
bun run build

# Generate launcher wrapper artifact
make build-launcher
# output: dist/launcher/subminer

# Full platform build (includes texthooker-ui + AppImage/DMG)
make build

# Platform-specific builds
make build-linux          # Linux AppImage
make build-macos          # macOS DMG + ZIP (signed)
make build-macos-unsigned # macOS DMG + ZIP (unsigned)

Launcher Artifact Workflow

• Source of truth: launcher/*.ts
• Generated output: dist/launcher/subminer
• Do not hand-edit generated launcher output.
• Repo-root ./subminer is a stale artifact path and is rejected by verification checks.
• Install targets (make install-linux, make install-macos) copy from dist/launcher/subminer.

Verify the workflow:

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

Running Locally

bun run dev    # builds + launches with --start --dev
electron . --start --dev --log-level debug   # equivalent Electron launch with verbose logging
electron . --background                       # tray/background mode, minimal default logging
make dev-start                                # build + launch via Makefile
make dev-watch                                # watch TS + renderer and launch Electron (faster edit loop)
make dev-watch-macos                          # same as dev-watch, forcing --backend macos

For mpv-plugin-driven testing without exporting SUBMINER_BINARY_PATH each run, set a one-time dev binary path in ~/.config/mpv/script-opts/subminer.conf:

binary_path=/absolute/path/to/SubMiner/scripts/subminer-dev.sh

Testing

CI-equivalent local gate:

bun run tsc --noEmit
bun run test:fast
bun run test:launcher:smoke:src
bun run build
bun run test:smoke:dist
bun run docs:build

Common focused commands:

bun run test:config       # Source-level config schema/validation tests
bun run test:launcher     # Launcher regression tests (config discovery + command routing)
bun run test:launcher:smoke:src # Launcher e2e smoke: launcher -> mpv IPC -> overlay start/stop wiring
bun run test:core         # Source-level core regression tests (default lane)
bun run test:fast         # Source-level config + core lane (no build prerequisite)
bun run test:immersion:sqlite:src # Source lane; warns/skips if node:sqlite is unavailable in Bun
bun run test:immersion:sqlite # Build + Node-backed SQLite persistence/finalization lane

Dist-level tests are now an explicit smoke lane used to validate compiled/runtime assumptions.

Launcher smoke artifacts are written to .tmp/launcher-smoke locally and uploaded by CI/release workflows when the smoke step fails.

Smoke and optional deep dist commands:

bun run build                 # compile dist artifacts
bun run test:immersion:sqlite # compile + run SQLite-backed immersion tests with Node --experimental-sqlite
bun run test:smoke:dist       # explicit smoke scope for compiled runtime
bun run test:config:dist      # optional full dist config suite
bun run test:core:dist        # optional full dist core suite

Use bun run test:immersion:sqlite when you need real DB-backed coverage for the immersion tracker. The Bun source lane may skip those tests when node:sqlite is unavailable, but the dedicated Node-backed lane is what CI/release now uses for reproducible persistence verification.

bun run test:subtitle and bun run test:subtitle:dist are currently placeholders and do not run an active suite.

Config Generation

# Generate default config to ~/.config/SubMiner/config.jsonc
make generate-config

# Regenerate the repo's config.example.jsonc from centralized defaults
make generate-example-config
# or: bun run generate:config-example

Documentation Site

The docs use VitePress:

make docs-dev     # Dev server at http://localhost:5173
make docs         # Build static output
make docs-preview # Preview built site at http://localhost:4173

Makefile Reference

Run make help for a full list of targets. Key ones:

Target	Description
make build	Build platform package for detected OS
make build-launcher	Generate Bun launcher wrapper at dist/launcher/subminer
make install	Install platform artifacts (wrapper, theme, AppImage/app bundle)
make install-plugin	Install mpv Lua plugin and config
make deps	Install JS dependencies (root + texthooker-ui)
make generate-config	Generate default config from centralized registry
make docs-dev	Run VitePress dev server

Contributor Notes

• To add/change a config default, edit the matching domain file in src/config/definitions/defaults-*.ts.
• To add/change config option metadata, edit the matching domain file in src/config/definitions/options-*.ts.
• To add/change generated config template blocks/comments, update src/config/definitions/template-sections.ts.
• Keep src/config/definitions.ts as the composed public API (DEFAULT_CONFIG, registries, template export) that wires domain modules together.
• Overlay window/visibility state is owned by src/core/services/overlay-manager.ts.
• Runtime architecture/module-boundary conventions are documented in Architecture; keep contributor changes aligned with that canonical guide.
• Linux packaged desktop launches pass --background using electron-builder build.linux.executableArgs in package.json.
• Prefer direct inline deps objects in src/main/ modules for simple pass-through wiring.
• Add a helper/adapter service only when it performs meaningful adaptation, validation, or reuse (not identity mapping).
