# Bevy Tasks
A **local-first, cross-platform tasks application** built with Rust. Inspired by Google Tasks, designed for speed and flexibility.
## Core Principles
- **Local-First**: Your data, your folder, your control
- **Fast**: Sub-second startup, instant response
- **Cross-Platform**: Single codebase, all platforms
- **Flexible**: Multiple workspaces for different contexts
## Project Structure
```

│ └── bevy-tasks-gui/ # GUI frontend (Phase 3+)
└── docs/
```
## Phase 1 Status: Core Library & CLI MVP ✅
Phase 1 implementation is complete with the following features:
### Core Library (`bevy-tasks-core`)
- ✅ Data models (Task, TaskList, AppConfig, WorkspaceConfig)
- ✅ Markdown file I/O with YAML frontmatter
- ✅ Local storage implementation
- ✅ Repository pattern with clean API
- ✅ Multiple workspace support
- ✅ Task ordering and grouping
### CLI (`bevy-tasks-cli`)
- ✅ Workspace management (init, add, list, switch, remove, retarget, migrate)
- ✅ Task list management (create, show, delete)
- ✅ Task operations (add, complete, delete, edit)
- ✅ Group-by-due-date toggle
- ✅ Support for `--workspace` flag on all commands
## Development Setup
### Prerequisites
- Rust 1.70+ (install from [rustup.rs](https://rustup.rs/))
- Git
### Build
```bash
# Clone and build
git clone <repository-url>
cd bevy-tasks
cargo build
# Run tests
cargo test -p bevy-tasks-core
# Run CLI
cargo run -p bevy-tasks-cli -- --help
```
## Quick Start
### Initialize your first workspace
```bash
# Initialize a new workspace
cargo run -p bevy-tasks-cli -- init ~/Documents/Tasks --name personal
# This creates:
# - A workspace named "personal" at ~/Documents/Tasks
# - A default list called "My Tasks"
# - Sets "personal" as the current workspace
```
### Add and manage tasks
```bash
# Add a task
cargo run -p bevy-tasks-cli -- add "Buy groceries"
# Add a task with due date
cargo run -p bevy-tasks-cli -- add "Review PR #123" --list "Work" --due "2025-11-15"
# List all tasks
cargo run -p bevy-tasks-cli -- list show
# Complete a task
cargo run -p bevy-tasks-cli -- complete <task-id>
# Edit a task (opens in $EDITOR)
cargo run -p bevy-tasks-cli -- edit <task-id>
# Delete a task
cargo run -p bevy-tasks-cli -- delete <task-id>
```
### Manage workspaces
```bash
# Add another workspace
cargo run -p bevy-tasks-cli -- workspace add shared ~/Dropbox/TeamTasks
# List workspaces
cargo run -p bevy-tasks-cli -- workspace list
# Switch workspace
cargo run -p bevy-tasks-cli -- workspace switch shared
# Use specific workspace for a command
cargo run -p bevy-tasks-cli -- add "Team meeting" --workspace shared
```
### Manage task lists
```bash
# Create a new list
cargo run -p bevy-tasks-cli -- list create "Work"
# Show tasks in a specific list
cargo run -p bevy-tasks-cli -- list show --list "Work"
# Delete a list
cargo run -p bevy-tasks-cli -- list delete "Work"
```
## Data Format
Tasks are stored as markdown files with YAML frontmatter (Obsidian-compatible):
```markdown
---
id: 550e8400-e29b-41d4-a716-446655440000
status: backlog
due: 2025-11-15T14:00:00Z
created: 2025-10-26T10:00:00Z
updated: 2025-10-26T12:30:00Z
---
Task description and notes go here in **markdown** format.
- Can include lists
- Rich formatting
- Links, etc.
```
## File System Structure
```
~/Documents/Tasks/ # User-selected folder
├── .metadata.json # Global: list ordering, last opened list
├── My Tasks/ # Task list folder
│ ├── .listdata.json # List metadata: task order, id, timestamps
│ ├── Buy groceries.md # Individual task files
│ └── Call dentist.md
└── Work/
├── .listdata.json
├── Review PRs.md
└── Team meeting prep.md
```
## Testing
Run the test suite:
```bash
# Run all tests
cargo test
# Run tests for specific crate
cargo test -p bevy-tasks-core
# Run tests with output
cargo test -- --nocapture
```
## What's Next?
- **Phase 2**: WebDAV sync for cross-device synchronization
- **Phase 3**: GUI with egui for desktop platforms
- **Phase 4**: Mobile support (iOS & Android)
- **Phase 5**: Advanced features and polish
- **Phase 6**: Platform-specific integrations
- **Phase 7**: Google Tasks importer and unique features
See [PLAN.md](PLAN.md) for detailed roadmap.

# Bevy Tasks Core - API Documentation
## Overview
The `bevy-tasks-core` library provides a complete backend for managing tasks in a local-first manner. Tasks are stored as markdown files with YAML frontmatter, compatible with Obsidian and other markdown editors.
## Core Concepts
### Data Models
#### Task
Represents an individual task.
```rust
pub struct Task {
pub id: Uuid,
pub title: String,
pub description: String,
pub status: TaskStatus,
pub due_date: Option<DateTime<Utc>>,
pub created_at: DateTime<Utc>,
pub updated_at: DateTime<Utc>,
pub parent_id: Option<Uuid>,
}
pub enum TaskStatus {
Backlog, // Not yet completed
Completed, // Done
}
```
**Creating a Task:**
```rust
use bevy_tasks_core::Task;
// Simple task
let task = Task::new("Buy groceries".to_string());
// Task with description and due date
let task = Task::new("Review PR #123".to_string())
.with_description("Check the authentication changes".to_string())
.with_due_date(chrono::Utc::now() + chrono::Duration::days(2));
```
#### TaskList
Represents a collection of tasks.
```rust
pub struct TaskList {
pub id: Uuid,
pub title: String,
pub tasks: Vec<Task>,
pub created_at: DateTime<Utc>,
pub updated_at: DateTime<Utc>,
pub group_by_due_date: bool,
}
```
### Configuration
#### AppConfig
Global application configuration supporting multiple workspaces.
```rust
pub struct AppConfig {
pub workspaces: HashMap<String, WorkspaceConfig>,
pub current_workspace: Option<String>,
}
```
**Location:**
- Windows: `%APPDATA%/bevy-tasks/config.json`
- Linux: `~/.config/bevy-tasks/config.json`
- macOS: `~/Library/Application Support/bevy-tasks/config.json`
**Usage:**
```rust
use bevy_tasks_core::AppConfig;
// Load config
let config_path = AppConfig::get_config_path();
let mut config = AppConfig::load_from_file(&config_path)?;
// Add workspace
config.add_workspace(
"personal".to_string(),
WorkspaceConfig::new(PathBuf::from("/home/user/tasks"))
);
// Set current workspace
config.set_current_workspace("personal".to_string())?;
// Save config
config.save_to_file(&config_path)?;
```
#### WorkspaceConfig
Configuration for a single workspace.
```rust
pub struct WorkspaceConfig {
pub path: PathBuf,
}
```
## TaskRepository API
The main interface for interacting with tasks and lists.
### Initialization
```rust
use bevy_tasks_core::TaskRepository;
use std::path::PathBuf;
// Open existing repository
let repo = TaskRepository::new(PathBuf::from("/path/to/tasks"))?;
// Initialize new repository
let repo = TaskRepository::init(PathBuf::from("/path/to/tasks"))?;
```
### Task Operations
#### Create Task
```rust
let task = Task::new("My task".to_string());
let created_task = repo.create_task(list_id, task)?;
```
#### Get Task
```rust
let task = repo.get_task(list_id, task_id)?;
```
#### Update Task
```rust
let mut task = repo.get_task(list_id, task_id)?;
task.title = "Updated title".to_string();
task.complete();
repo.update_task(list_id, task)?;
```
#### Delete Task
```rust
repo.delete_task(list_id, task_id)?;
```
#### List Tasks
```rust
let tasks = repo.list_tasks(list_id)?;
```
### List Operations
#### Create List
```rust
let list = repo.create_list("My List".to_string())?;
```
#### Get Lists
```rust
let lists = repo.get_lists()?;
```
#### Get Specific List
```rust
let list = repo.get_list(list_id)?;
```
#### Delete List
```rust
repo.delete_list(list_id)?;
```
### Task Ordering
#### Reorder Task
```rust
// Move task to position 0 (first)
repo.reorder_task(list_id, task_id, 0)?;
```
#### Get Task Order
```rust
let order = repo.get_task_order(list_id)?;
// Returns: Vec<Uuid> - ordered list of task IDs
```
### Grouping
#### Enable/Disable Group by Due Date
```rust
// Enable grouping
repo.set_group_by_due_date(list_id, true)?;
// Disable grouping
repo.set_group_by_due_date(list_id, false)?;
// Check current setting
let is_grouped = repo.get_group_by_due_date(list_id)?;
```
## File Format
### Task Files
Tasks are stored as `.md` files with YAML frontmatter:
```markdown
---
id: 550e8400-e29b-41d4-a716-446655440000
status: backlog
due: 2025-11-15T14:00:00Z
created: 2025-10-26T10:00:00Z
updated: 2025-10-26T12:30:00Z
parent: 550e8400-e29b-41d4-a716-446655440001
---
Task description and notes go here in **markdown** format.
- Can include lists
- Rich formatting
- Links, etc.
```
The filename (without `.md`) becomes the task title.
### List Metadata
Each list folder contains a `.listdata.json` file:
```json
{
"id": "list-uuid-1",
"created_at": "2025-10-26T10:00:00Z",
"updated_at": "2025-10-27T14:30:00Z",
"group_by_due_date": false,
"task_order": [
"task-uuid-1",
"task-uuid-2",
"task-uuid-3"
]
}
```
### Root Metadata
The root folder contains a `.metadata.json` file:
```json
{
"version": 1,
"list_order": ["list-uuid-1", "list-uuid-2"],
"last_opened_list": "list-uuid-1"
}
```
## Error Handling
All operations return `Result<T, Error>` where `Error` is:
```rust
pub enum Error {
Io(io::Error),
Serialization(String),
NotFound(String),
InvalidData(String),
WorkspaceNotFound(String),
ListNotFound(String),
TaskNotFound(String),
}
```
## Example: Complete Workflow
```rust
use bevy_tasks_core::{TaskRepository, Task, AppConfig, WorkspaceConfig};
use std::path::PathBuf;
fn main() -> Result<(), Box<dyn std::error::Error>> {
// Initialize repository
let path = PathBuf::from("/home/user/tasks");
let mut repo = TaskRepository::init(path.clone())?;
// Create a list
let list = repo.create_list("My Tasks".to_string())?;
// Create tasks
let task1 = Task::new("Buy groceries".to_string());
let task1 = repo.create_task(list.id, task1)?;
let task2 = Task::new("Call dentist".to_string())
.with_due_date(chrono::Utc::now() + chrono::Duration::days(1));
let task2 = repo.create_task(list.id, task2)?;
// List all tasks
let tasks = repo.list_tasks(list.id)?;
for task in tasks {
println!("- [{}] {}",
if task.status == TaskStatus::Completed { "✓" } else { " " },
task.title
);
}
// Complete a task
let mut task = repo.get_task(list.id, task1.id)?;
task.complete();
repo.update_task(list.id, task)?;
// Configure workspace
let mut config = AppConfig::new();
config.add_workspace("personal".to_string(), WorkspaceConfig::new(path));
config.set_current_workspace("personal".to_string())?;
config.save_to_file(&AppConfig::get_config_path())?;
Ok(())
}
```
## Testing
The core library includes comprehensive tests. Run them with:
```bash
cargo test -p bevy-tasks-core
```
Key test areas:
- Task CRUD operations
- List management
- Task ordering
- Markdown parsing
- Metadata persistence
- Error handling
## Thread Safety
**Note:** The current implementation is not thread-safe. If you need concurrent access:
1. Use external synchronization (e.g., `Mutex<TaskRepository>`)
2. Create separate repository instances per thread (file system will handle locking)
3. Consider implementing a service layer with proper locking
Future versions may include built-in concurrency support.

## Development Workflow
### Running Tests
```bash
# Run all tests
cargo test
# Run tests for a specific crate
cargo test -p bevy-tasks-core
# Run a specific test
cargo test -p bevy-tasks-core test_create_and_list_tasks
# Run tests with output
cargo test -- --nocapture
```
### Building
```bash
# Debug build
cargo build
# Release build (optimized)
cargo build --release
# Build specific crate
cargo build -p bevy-tasks-cli
```
### Running the CLI in Development
```bash
# Run with cargo (recommended for development)
cargo run -p bevy-tasks-cli -- init ~/test-tasks --name test
# Run the compiled binary
./target/debug/bevy-tasks init ~/test-tasks --name test
```
## Code Style
### Formatting
We use rustfmt for code formatting:
```bash
# Format all code
cargo fmt
# Check formatting without modifying files
cargo fmt -- --check
```
### Linting
We use clippy for linting:
```bash
# Run clippy
cargo clippy
# Run clippy with all warnings
cargo clippy -- -W clippy::all
```
## Architecture Guidelines
### Core Library (`bevy-tasks-core`)
**Principles:**
- Pure Rust, no CLI dependencies
- Clear separation between models, storage, and repository
- Comprehensive error handling
- Well-tested (aim for >80% coverage)
**Adding a new feature:**
1. Start with the data model in `models.rs`
2. Update storage layer in `storage.rs` if needed
3. Add repository methods in `repository.rs`
4. Write tests
5. Update API documentation
### CLI (`bevy-tasks-cli`)
**Principles:**
- Thin layer over core library
- Clear command structure using clap
- User-friendly output with colored text
- Consistent error messages
**Adding a new command:**
1. Define command in `main.rs` using clap
2. Create command handler in `commands/` directory
3. Use `get_repository()` helper to access the core
4. Format output using `output.rs` helpers
5. Update README with usage examples
## Testing Strategy
### Unit Tests
Located in the same file as the code they test:
```rust
#[cfg(test)]
mod tests {
use super::*;
#[test]
fn test_something() {
// Test code
}
}
```
### Integration Tests
Located in `tests/` directories within each crate:
```rust
// crates/bevy-tasks-core/tests/integration_test.rs
use bevy_tasks_core::*;
#[test]
fn test_full_workflow() {
// Test complete workflows
}
```
### Test Data
Use `tempfile` crate for temporary directories:
```rust
use tempfile::TempDir;
#[test]
fn test_with_temp_dir() {
let temp_dir = TempDir::new().unwrap();
let repo = TaskRepository::init(temp_dir.path().to_path_buf()).unwrap();
// ... test code
}
```
## Common Tasks
### Adding a New Field to Task
1. Update `Task` struct in `models.rs`
2. Update `TaskFrontmatter` in `storage.rs`
3. Update markdown parsing/writing in `storage.rs`
4. Add migration logic if needed
5. Update tests
6. Update documentation
### Adding a New CLI Command
1. Add command to `Commands` enum in `main.rs`
2. Add match arm in `main()` function
3. Create command handler in `commands/` directory
4. Update README with usage example
### Debugging Storage Issues
Enable detailed logging:
```rust
// In test or development code
std::env::set_var("RUST_LOG", "debug");
```
Inspect the file system directly:
```bash
# Check metadata
cat ~/test-tasks/.metadata.json | jq
# Check list metadata
cat ~/test-tasks/My\ Tasks/.listdata.json | jq
# Check task file
cat ~/test-tasks/My\ Tasks/Example\ task.md
```
## Release Process
### Version Numbering
We follow [Semantic Versioning](https://semver.org/):
- MAJOR: Incompatible API changes
- MINOR: New functionality, backwards compatible
- PATCH: Bug fixes, backwards compatible
### Creating a Release
1. Update version in all `Cargo.toml` files
2. Update `CHANGELOG.md`
3. Create git tag: `git tag v0.1.0`
4. Build release binaries: `cargo build --release`
5. Test release binaries
6. Push tag: `git push origin v0.1.0`
## Troubleshooting
### Cargo Build Fails
```bash
# Clean build artifacts
cargo clean
# Update dependencies
cargo update
# Check for errors
cargo check
```
### Tests Fail
```bash
# Run single test with output
cargo test test_name -- --nocapture
# Check for file system issues
ls -la ~/test-tasks
```
### CLI Command Doesn't Work
```bash
# Verify workspace configuration
cat ~/.config/bevy-tasks/config.json | jq
# Check current workspace
cargo run -p bevy-tasks-cli -- workspace list
# Initialize if needed
cargo run -p bevy-tasks-cli -- init ~/test-tasks --name test
```
## Contributing
### Before Submitting a PR
1. Run tests: `cargo test`
2. Format code: `cargo fmt`
3. Lint code: `cargo clippy`
4. Update documentation
5. Add tests for new features
6. Update CHANGELOG.md
