## 📋 Task Workflow
### Task Status
- ⬜ **Not Started** - Available for assignment
- 🟡 **In Progress** - Currently being worked on
- ✅ **Completed** - Done and merged
- 🔄 **Blocked** - Waiting on dependencies
- ❌ **Cancelled** - No longer needed
### Updating Task Status
Update status in `roadmap/TASKS.md` when:
- Starting: ⬜ → 🟡
- Completing: 🟡 → ✅
- Blocked: 🟡 → 🔄
**Note:** Update via PR, not directly in main branch.
## 🛠️ Development Guidelines
### Code Style
- Follow Rust standard formatting (`cargo fmt`)
- Run clippy and fix warnings (`cargo clippy`)
- Use 4 spaces for indentation
- Keep line length < 100 characters
- Follow Rust naming conventions
### Pre-commit Hooks
A pre-commit hook is automatically installed that runs the following checks before each commit:
1. **Code Formatting** (`cargo fmt --check`)
- Ensures code follows Rust standard formatting
- If formatting fails, run `cargo fmt` to auto-format
2. **Clippy** (`cargo clippy -- -D warnings`)
- Catches common mistakes and enforces idiomatic Rust
- All warnings must be fixed before committing
3. **Compilation Check** (`cargo check`)
- Verifies code compiles successfully
- Catches compilation errors early
4. **Tests** (`cargo test`)
- Runs all tests to ensure nothing is broken
- All tests must pass before committing
**Note:** If you need to skip the pre-commit hook (e.g., for WIP commits), use `git commit --no-verify`. However, **never skip hooks for final commits** - all checks must pass before merging.
### Zero Dependencies Principle
**CRITICAL:** The core library must use only Rust's standard library.
- ✅ Use `std` only for core functionality
- ✅ Optional features (like `serde`) behind feature flags
- ❌ Never add dependencies to core library
- ✅ Dev-dependencies (like `criterion`) are OK for benchmarks
### Testing
- Write tests for all public functions
- Test edge cases (empty strings, Unicode, special chars)
- Run `cargo test` before submitting
- Aim for 100% test coverage
### Documentation
- Every public function needs doc comments (`///`)
- Include `# Examples` section
- Document security use cases
- Reference related functions
### Performance
- Use `String::with_capacity` when size is known
- Avoid unnecessary allocations
- Profile performance-critical paths
- Benchmark new functions
## 📝 Commit Messages
**We enforce conventional commits using `cc-check` in CI.**
### Format
```
[TASK-ID] <type>(<scope>): <subject>
<body>
<footer>
```
### Types
- `feat`: New feature
- `fix`: Bug fix
- `docs`: Documentation changes
- `style`: Code style changes (formatting, etc.)
- `refactor`: Code refactoring
- `test`: Adding or updating tests
- `chore`: Maintenance tasks
- `perf`: Performance improvements
### Examples
```
[CF-001] feat(cloudflare): add Turnstile challenge variation
Implements cloudflare_turnstile_variation() for bot detection evasion.
- Add function to cloudflare.rs
- Add comprehensive tests
- Add documentation with examples
Closes #123
```
```
[PKG-001] feat(packaging): create Debian package structure
Adds debian/ directory with control, rules, and changelog files.
- Create debian/control
- Add debian/rules for building
- Add debian/changelog
```
```
fix(encoding): correct URL encoding for special characters
Fixes issue where certain Unicode characters were not properly encoded.
Fixes #456
```
### Validation
Commit messages are automatically validated in CI. The format must be:
```
[TASK-ID] <type>(<scope>): <subject>
```
Where:
- `TASK-ID` is optional but recommended (e.g., `CF-001`)
- `type` is required (feat, fix, docs, etc.)
- `scope` is optional (module name)
- `subject` is required (brief description)
**CI will fail if commits don't follow this format.**
## 🚀 Release Process
### Creating a Release
We use [`cargo-release`](https://github.com/crate-ci/cargo-release) to automate the release process and prevent version mismatches.
#### Prerequisites
Install `cargo-release` (one-time setup):
```bash
cargo install cargo-release
```
#### Recommended: Use cargo-release
The easiest way to create a release is using `cargo-release`:
**For semantic versioning:**
```bash
cargo release patch # 0.1.0 -> 0.1.1
cargo release minor # 0.1.0 -> 0.2.0
cargo release major # 0.1.0 -> 1.0.0
```
**For specific version:**
```bash
cargo release 0.2.0
```
**Dry run (preview changes without committing):**
```bash
cargo release --dry-run patch
```
`cargo-release` will:
1. ✅ Update `Cargo.toml` version
2. ✅ Update `Cargo.lock` if needed
3. ✅ Create a git commit with the version change
4. ✅ Create a git tag `v<version>`
5. ✅ Optionally push to origin (use `--execute` flag)
**Full release workflow:**
```bash
# Preview what will happen
cargo release --dry-run minor
# Execute the release (updates version, commits, tags)
cargo release minor --execute
# Push the commit and tag
git push origin main
git push origin --tags
```
### CI Validation & Publishing
The GitHub Actions workflow automatically:
- ✅ Validates that `Cargo.toml` version matches the tag version
- ✅ Publishes to crates.io when validation passes
- ✅ Uses Trusted Publishing (no API tokens needed)
**Workflow:** Push tag → CI validates → Auto-publishes to crates.io
## 🔍 Code Review Process
1. **Automated Checks**
- Tests must pass
- Clippy must pass
- Formatting must be correct
2. **Review Criteria**
- Code follows style guide
- Tests are comprehensive
- Documentation is complete
- Zero dependencies maintained
- Performance considered
3. **Review Feedback**
- Address all comments
- Update code as needed
- Re-request review when ready
## 🎯 Task Priorities
### Priority Levels
- **Critical**: Must have for next release
- **High**: Important feature
- **Medium**: Nice to have
- **Low**: Future consideration
### Complexity Levels
- **Simple**: 1-2 days
- **Medium**: 3-5 days
- **Complex**: 1-2 weeks

## 🚀 Quick Start Examples
### Adding a New Transformation Function
1. Create function in appropriate module:
```rust
pub fn new_function(input: &str) -> String {
}
```
2. Add tests:
```rust
#[cfg(test)]
mod tests {
use super::*;
#[test]
fn test_new_function() {
}
}
```
3. Export in `src/lib.rs`:
```rust
pub use transformations::cloudflare::new_function;
```
4. Add to `TransformBuilder` if applicable
5. Create example in `examples/`
### Creating a New Integration
1. Research integration points
2. Create `docs/{platform}_integration.md`
3. Create `integrations/{platform}/` directory
4. Implement integration
5. Add examples and documentation
