# Contributing to PolyScribe
# Contributing
Thanks for your interest in contributing! This guide explains the workflow and the checklist to follow before opening a Pull Request.
Thank you for your interest in contributing!
Workflow (fork → branch → PR)
1) Fork the repository to your account.
2) Create a feature branch:
- git checkout -b feat/short-description
3) Make changes with focused commits and good messages.
4) Run the checklist below.
5) Push and open a Pull Request against the main repository.
Development setup
- Install Rust via rustup.
- Ensure ffmpeg is installed and available on PATH.
- For GPU builds, install the appropriate runtime (CUDA/ROCm/Vulkan) and enable the matching features.
Developer checklist (before opening a PR)
- Build:
- cargo build (preferably without warnings)
- Tests:
- cargo test (all tests pass)
- Lints:
- cargo clippy --all-targets -- -D warnings (fix warnings)
- Documentation:
- Update README/docs for user-visible changes
- Update CHANGELOG.md if applicable
- Tests for changes:
- Add or update tests for bug fixes and new features where reasonable
Coding guidelines
- Prefer small, focused changes.
- Add tests where reasonable.
- Keep user-facing changes documented in README/docs.
- Run clippy and fix warnings.
Local development tips
- Use `cargo run -- <args>` during development.
- For faster feedback, keep examples in the examples/ folder handy.
- Keep functions small and focused; prefer clear error messages with context.
CI checklist
- Build: cargo build --all-targets --locked
- Tests: cargo test --all --locked
- Lints: cargo clippy --all-targets -- -D warnings
- Optional: smoke-run examples inline (from README):
- ./target/release/polyscribe --update-models --no-interaction -q
- ./target/release/polyscribe -o output samples/podcast_clip.mp3
Code of conduct
- Be respectful and constructive. Assume good intent.
Notes
- For GPU features, use --features gpu-cuda|gpu-hip|gpu-vulkan as needed in your local runs.
- For docs-only changes, please still ensure the project builds.

# Pull Request: PolyScribe workspace + plugin system
This PR refactors the repository into a multi-crate Cargo workspace and adds a minimal, working plugin system scaffold over NDJSON/stdio, while preserving existing CLI behavior. It also introduces a stub plugin `polyscribe-plugin-tubescribe` and documentation updates.
Differences & Adaptations
- The repository already contained most of the workspace and plugin scaffolding; this PR focuses on completing and verifying the setup, fixing a symlink path issue in the plugin Makefile, and adding documentation and minor cleanup.
- Existing CLI commands and flags are preserved; a new `plugins` command group is added (list/info/run) without breaking existing outputs.
## Commits
### 1) chore(workspace): scaffold workspace + move crates
Rationale
- Ensure workspace members and resolver are properly defined. The repository already contained these crates; this commit documents the layout and confirms no absolute paths are used.
Updated files (representative snapshots)
- Cargo.toml (workspace):
```
[workspace]
members = [
"crates/polyscribe-core",
"crates/polyscribe-protocol",
"crates/polyscribe-host",
"crates/polyscribe-cli",
"plugins/polyscribe-plugin-tubescribe",
]
resolver = "2"
```

├── Cargo.toml
├── crates
│ ├── polyscribe-cli
│ ├── polyscribe-core
│ ├── polyscribe-host
│ └── polyscribe-protocol
└── plugins
└── polyscribe-plugin-tubescribe
```
### 2) feat(plugins): host/stdio runner + CLI plugin commands
Rationale
- Provide plugin discovery and stdio NDJSON JSON-RPC runner in host crate; add `plugins` subcommands to CLI. These were already implemented; this commit verifies and documents behavior.
Updated files (representative snapshots)
- crates/polyscribe-host/src/lib.rs: discover(), capabilities(), run_method().
- crates/polyscribe-cli/src/main.rs: `plugins list|info|run` wired to host, forwarding progress.
Repository tree after this commit: unchanged from above.
### 3) feat(plugin): add stub polyscribe-plugin-tubescribe + docs
Rationale (risky change explained)
- Fixed a symlink path issue in the Makefile by switching from $(PWD) to $(CURDIR) to avoid brittle relative paths. This ensures discovery finds the plugin consistently on all shells.
- Removed an unused import to keep clippy clean.
- Added README docs covering workspace layout and verification commands.
Updated files (full contents included in repo):
- plugins/polyscribe-plugin-tubescribe/Makefile
- plugins/polyscribe-plugin-tubescribe/src/main.rs
- README.md (appended Workspace & Plugins section)

## Verification commands
- Build the workspace:
- cargo build --workspace --all-targets
- Show CLI help and plugin subcommands:
- cargo run -p polyscribe-cli -- --help
- Discover plugins (before linking, likely empty):
- cargo run -p polyscribe-cli -- plugins list
- Build and link the stub plugin:
- make -C plugins/polyscribe-plugin-tubescribe link
- Discover again:
- cargo run -p polyscribe-cli -- plugins list
- Show plugin capabilities:
- cargo run -p polyscribe-cli -- plugins info tubescribe
- Run a plugin command and observe progress + JSON result:
- cargo run -p polyscribe-cli -- plugins run tubescribe generate_metadata --json '{"input":{"kind":"text","summary":"hello world"}}'
All acceptance checks pass locally.

# CI checklist and job outline
Checklist to keep docs and code healthy in CI
- Build: cargo build --all-targets --locked
- Tests: cargo test --all --locked
- Lints: cargo clippy --all-targets -- -D warnings
- Optional: check README and docs snippets (basic smoke run of examples scripts)
- bash examples/update_models.sh (can be skipped offline)
- bash examples/transcribe_file.sh (use a tiny sample file if available)
Example GitHub Actions job (outline)
- name: Rust
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: dtolnay/rust-toolchain@stable
- name: Build
run: cargo build --all-targets --locked
- name: Test
run: cargo test --all --locked
- name: Clippy
run: cargo clippy --all-targets -- -D warnings
Notes
- For GPU features, set up appropriate runners and add `--features gpu-cuda|gpu-hip|gpu-vulkan` where applicable.
- For docs-only changes, jobs still build/test to ensure doctests and examples compile when enabled.
