Development

Prerequisites

• Node.js (LTS)
• pnpm
• Bun (for the subminer wrapper script)

Setup

git clone https://github.com/ksyasuda/SubMiner.git
cd SubMiner
make deps
# or manually:
pnpm install
pnpm -C vendor/texthooker-ui install

Building

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

# 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)

Running Locally

pnpm run dev    # builds + launches with --start --dev flags

Testing

pnpm run test:config       # Config schema and validation tests (build + run)
pnpm run test:core         # Core service tests (~67 tests) (build + run)
pnpm run test:subtitle     # Subtitle pipeline tests (build + run)

All legacy test commands build first, then run via Node's built-in test runner (node --test).

For faster iteration while editing test code:

pnpm run build             # one-time compile
pnpm run test:config:dist  # no rebuild
pnpm run test:core:dist    # no rebuild
pnpm run test:subtitle:dist # no rebuild
pnpm run test:fast         # run all tests without rebuild (assumes build is already current)

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: pnpm 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 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 or change a config option, update src/config/definitions.ts first. Defaults, runtime-option metadata, and generated config.example.jsonc are derived from this centralized source.
• Overlay window/visibility state is owned by src/core/services/overlay-manager-service.ts.
• Main process composition is now split across src/main/ modules (startup.ts, app-lifecycle.ts, startup-lifecycle.ts, state.ts, ipc-runtime.ts, cli-runtime.ts, overlay-runtime.ts, subsync-runtime.ts).
• MPV service has been split into transport, protocol, state, and properties layers in src/core/services/.
• 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).
• See Architecture for the composition model and extension rules.
