Installation

pip install nekoconf

or build from source

pip install -e .

Quick Start

Web UI

Start the web server to manage your configuration through a browser:

nekoconf server --config config.yaml

This starts a web server at http://127.0.0.1:8000 where you can view and edit your configuration.

NekoConf features a modern web interface with both dark and light themes:

Command Line Interface

# View a configuration
nekoconf get --config config.yaml server.host

# Update a value
nekoconf set --config config.yaml server.port 8080

# Delete a value
nekoconf delete --config config.yaml unused.feature

# Import from another file
nekoconf import --config config.yaml other_config.json

# Create a new empty configuration file
nekoconf init --config new_config.yaml

# Validate against a schema
nekoconf validate --config config.yaml --schema schema.json

Python API

from nekoconf import ConfigAPI

# Initialize with your configuration file
config = ConfigAPI("config.yaml")

# Get values with type safety
host = config.get_str("server.host", "localhost")
port = config.get_int("server.port", 8080)
debug = config.get_bool("server.debug", False)

# Update values
config.set("server.host", "127.0.0.1")

# Observe changes
def on_config_change(config_data):
    print("Configuration changed:", config_data)

config.observe(on_config_change)

Advanced Usage

Async Support

NekoConf supports asynchronous observers for configuration changes:

import asyncio
from nekoconf import ConfigAPI

async def async_observer(config_data):
    print("Configuration changed!")
    await asyncio.sleep(0.1)  # Async processing
    print(f"Processed: {config_data}")

async def main():
    config = ConfigAPI("config.yaml")
    config.observe(async_observer)
    
    # Make a change
    config.set("server.port", 9000)
    
    # Wait for processing
    await asyncio.sleep(0.2)

asyncio.run(main())

Schema Validation

Validate your configuration against a schema:

from nekoconf import ConfigAPI

# Initialize with a schema
config = ConfigAPI("config.yaml", schema_path="schema.json")

# Validate configuration
errors = config.validate()
if errors:
    print("Validation errors:", errors)

Bulk Updates

Update multiple values at once:

from nekoconf import ConfigAPI

config = ConfigAPI("config.yaml")

# Update multiple values with deep merge
config.update({
    "server": {
        "host": "127.0.0.1",
        "port": 9000
    }
})

Framework Integration

FastAPI Example

from fastapi import FastAPI, Depends
from nekoconf import ConfigAPI

app = FastAPI()
config = ConfigAPI("config.yaml")

def get_config():
    return config

@app.get("/api/config")
def read_config(config=Depends(get_config)):
    return config.get_all()

Flask Example

from flask import Flask
from nekoconf import ConfigAPI

app = Flask(__name__)
config = ConfigAPI("config.yaml")

# Update Flask config when NekoConf changes
def sync_flask_config(config_data):
    app.config.update(config_data)

config.observe(sync_flask_config)

Django Example

from django.apps import AppConfig
from nekoconf import ConfigAPI

class MyAppConfig(AppConfig):
    name = 'myapp'
    
    def ready(self):
        from django.conf import settings
        
        config = ConfigAPI("config.yaml")
        
        # Update Django settings when configuration changes
        def update_settings(config_data):
            for key, value in config_data.items():
                if hasattr(settings, key.upper()):
                    setattr(settings, key.upper(), value)
        
        config.observe(update_settings)

API Reference

ConfigAPI

The main interface for applications to interact with configuration:

# Core methods
config.get(key, default=None)  # Get any value
config.get_str(key, default=None)  # Get string value
config.get_int(key, default=None)  # Get integer value
config.get_bool(key, default=None)  # Get boolean value
config.get_float(key, default=None)  # Get float value
config.get_dict(key, default=None)  # Get dictionary value
config.get_list(key, default=None)  # Get list value

# Update methods
config.set(key, value)  # Set a value
config.delete(key)  # Delete a value
config.update(data, deep_merge=True)  # Update multiple values

# Observer pattern
config.observe(callback)  # Register change observer
config.stop_observing(callback)  # Remove observer

# Other operations
config.reload()  # Reload from file
config.validate()  # Validate against schema
config.get_all()  # Get entire configuration

ConfigManager

Low-level class for managing configuration files:

manager = ConfigManager("config.yaml")
manager.load()  # Load from file
manager.save()  # Save to file
manager.register_observer(callback)  # Add observer

NekoConf

Web server for managing configuration through a UI:

server = NekoConf(config_manager)
server.run(host="127.0.0.1", port=8000)

Securing the Web Interface and API

You can secure the web interface and API with password authentication:

from nekoconf import ConfigManager, NekoConf

# Create a config manager
config = ConfigManager("config.yaml")

# Create a web server with authentication
server = NekoConf(
    config_manager=config,
    username="admin",  # Default username
    password="mysecretpassword"  # Set your password here
)

# Run the server
server.run(host="0.0.0.0", port=8000)

Using the command line:

nekoconf server --config=config.yaml --username=admin --password=mysecretpassword

If no password is provided, authentication will be disabled.

API Access with Authentication

When authentication is enabled, you need to provide credentials for API access:

# Get the entire configuration
curl -u admin:mysecretpassword http://localhost:8000/api/config

# Get a specific configuration value
curl -u admin:mysecretpassword http://localhost:8000/api/config/server/host

# Update a configuration value
curl -u admin:mysecretpassword -X POST \
  -H "Content-Type: application/json" \
  -d '{"value": "new_value"}' \
  http://localhost:8000/api/config/server/host

# Reload the configuration from disk
curl -u admin:mysecretpassword -X POST http://localhost:8000/api/config/reload

Development

Set up a development environment:

git clone https://github.com/nya-foundation/nekoconf.git
cd nekoconf
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install -e ".[dev]"

Run tests:

pytest
pytest --cov=nekoconf
