Quick Start

Basic Usage

from todowrite import ToDoWrite

# Initialize the application
app = ToDoWrite("sqlite:///myproject.db")
app.init_database()

# Create a goal
goal_data = {
    "id": "GOAL-001",
    "layer": "Goal",
    "title": "Implement User Authentication",
    "description": "Create secure user authentication system",
    "metadata": {
        "owner": "developer1",
        "labels": ["security", "auth"],
        "severity": "high",
        "work_type": "implementation"
    }
}
goal = app.create_node(goal_data)

# Create a task
task_data = {
    "id": "TSK-001",
    "layer": "Task",
    "title": "Design Database Schema",
    "description": "Design and implement database schema for users",
    "metadata": {
        "owner": "developer1",
        "labels": ["database"],
        "severity": "medium",
        "work_type": "design"
    }
}
task = app.create_node(task_data)

# Link task to goal
app.link_nodes("GOAL-001", "TSK-001")

# Update progress
app.update_node("TSK-001", {"status": "in_progress", "progress": 50})

Using Different Storage Backends

SQLite

app = ToDoWrite("sqlite:///project.db")
app.init_database()

PostgreSQL

app = ToDoWrite("postgresql://user:password@localhost/projectdb")
app.init_database()

YAML Storage

app = ToDoWrite("sqlite:///project.db", yaml_base_path="./configs")
app.init_database()

Advanced Operations

Complex Hierarchies

# Create a multi-level hierarchy
goal = app.create_node({
    "id": "GOAL-001",
    "layer": "Goal",
    "title": "Main Project Goal"
})

concept1 = app.create_node({
    "id": "CON-001",
    "layer": "Concept",
    "title": "Architecture Concept"
})

concept2 = app.create_node({
    "id": "CON-002",
    "layer": "Concept",
    "title": "Security Concept"
})

task1 = app.create_node({
    "id": "TSK-001",
    "layer": "Task",
    "title": "Implementation Task 1"
})

task2 = app.create_node({
    "id": "TSK-002",
    "layer": "Task",
    "title": "Implementation Task 2"
})

# Link everything together
app.link_nodes("GOAL-001", "CON-001")
app.link_nodes("GOAL-001", "CON-002")
app.link_nodes("GOAL-001", "TSK-001")
app.link_nodes("GOAL-001", "TSK-002")

Batch Operations

# Create multiple nodes
nodes_data = [
    {"id": "GOAL-001", "layer": "Goal", "title": "Goal 1"},
    {"id": "GOAL-002", "layer": "Goal", "title": "Goal 2"},
    {"id": "TSK-001", "layer": "Task", "title": "Task 1"},
    {"id": "TSK-002", "layer": "Task", "title": "Task 2"}
]

for node_data in nodes_data:
    app.create_node(node_data)

# Get all goals
goals = app.get_nodes("Goal")

Querying and Filtering

# Get nodes by status
incomplete_tasks = app.get_nodes("Task", {"status": "in_progress"})

# Get nodes by owner
developer_tasks = app.get_nodes("Task", {"owner": "developer1"})

# Get nodes by label
critical_nodes = app.get_nodes_by_label("critical")

# Get node with links
node_with_links = app.get_node_with_links("GOAL-001")

YAML Integration

# Export nodes to YAML
from todowrite.storage.yaml_manager import YAMLManager

yaml_manager = YAMLManager(app)
yaml_manager.export_to_yaml("./exported")

# Import nodes from YAML
yaml_manager.import_yaml_files()

# Check sync status
sync_status = yaml_manager.check_yaml_sync()

Validation

# Validate node data
from todowrite.storage.validators import validate_node_data

try:
    validate_node_data(node_data)
    print("Node data is valid")
except Exception as e:
    print(f"Invalid node data: {e}")

# Validate database schema
from todowrite.storage.validators import validate_database_schema

schema_valid = validate_database_schema()

Custom Metadata

# Add custom metadata fields
node_data = {
    "id": "GOAL-001",
    "layer": "Goal",
    "title": "Custom Goal",
    "metadata": {
        "owner": "developer",
        "labels": ["custom"],
        "severity": "medium",
        "work_type": "implementation",
        "custom_field": "custom_value",
        "another_field": 42
    }
}
