shadecrypt 0.2.9

A lightweight, class-oriented database server with a CLI wrapper for instant querying on any device.Store, update, fetch, and remove structured data with a single command. Designed for speed and simplicity, it’s perfect for embedded systems, mobile devices, developer tools, and quick local services.

♟️ Mission

🚀 shadecrypt, also know as shadeDB beta, is a lightweight, multipurpose CLI + api database server — small enough to run anywhere, yet powerful enough to manage structured data with speed and simplicity.

Unlike traditional file-based CLIs, shadecrypt works more like Redis:

• You initialize once → a background server process holds the live database in memory.
• All future CLI commands (put, get, update, etc.) talk to that server via a local socket.
• The server automatically persists data to a .scdb file, with optional write and backup controls.

---

✨ Features

• Class-oriented design — core database logic is in the shadecrypt class.
• Persistent workflow — one live server handles all operations.
• Background persistence — in-memory with disk persistence.
• Portable — runs on Linux, macOS, Windows, Android (via Termux).
• Multipurpose CLI — simple commands: init, start, use, pull, get, update, remove, ls, stop.
• Config-aware — automatically tracks the “current” DB in ~/.shadecrypt/config.scdb.

🔧 Installation

pip install shadecrypt

After install, the shadecrypt command is available globally. A shorter keyword for shadecrypt - scdb

---

⚡ Quickstart (CLI)

1. Initialize a database

Creates ./mydb.scdb, starts the server, and sets it as default:

shadecrypt init ./mydb.scdb backup

⚠️ Only provide the "backup" argument if you intend for the server to register newer backups as you make new changes.

2. Start database server

This is necessary, as the cli wrapper only communicates with the database server to retrieve,update,remove and store data.

3. Insert data

shadecrypt update alice.age 17 && scdb update alice.gender female

---

4. Fetch data

shadecrypt get alice
# {"nickname": "Shade", "status": "active"}

---

5. Nested access

shadecrypt pull alice.nickname
# "Shade"

---

Making single value updates, it is compulsory to surround with double quotes.

6. Update

shadecrypt update alice "my name is alice"

---

7. Remove

shadecrypt remove alice 
# deletes {"nickname":"shade","status":"active"}

8. Remove nested

shadecrypt remove alice.nickname
# deletes {"nickname":"shade"} 

---

9. Check for the current database

shadecrypt ls
# ./mysql.scsb

---

10. Switch database

shadecrypt use ./backup.scdb backup
# Only provide the backup argument, if it need arises.

---

11. Stop server

shadecrypt stop

---

📚 Python API

shadecrypt can also be embedded directly into Python apps using the shadecrypt class.

🔧 Initialize

from shadecrypt.core import shadecrypt

db = shadecrypt(
    file="./data.scdb",
    write=True,
    id=True,
    backup=False,
    silent=False
)

Parameters

• file (str) → Path to .scdb file
• write (bool) → Persist changes to disk (default: True)
• id (bool) → Assign unique ID per entry (default: True)
• backup (bool) → Keep backup copy (default: False)
• silent (bool) → Whether to display a welcome message via cli on the disk's first initialisation

🛠️ Key Methods

db.update(("alice", {"nickname": "Shade", "status": "active"}))   # Insert/update
db.get("alice", multiple=True/False)      # Fetch record
db.get("alice.nickname")  # Fetch nested value
db.get_context("alice")   # Get full dict
db.get_by_id(1) # Fetch by ID
db.get_id("alice",multiple=True/False) # Get ID of key
db.items()                # List all entries
db.import_dict({...},overwrite=True/False)     # Import dictionary, can also overwrite existing records
db.export_dict()          # Export to dictionary
db.remove("alice")        # Delete entry
db.clear()                # Clear all
db.status()               # DB status
db.__performance__()      # Performance stats

---

⚡ Example Workflow

from shadecrypt.core import shadecrypt

db = shadecrypt("./appdata.scdb", write=True)

# Insert
db.update(("alice", {"nickname": "Shade", "status": "active"}))

# Nested access
print(db.get("alice.nickname"))   # Shade

# Full context
print(db.get_context("alice"))    # {'nickname': 'Shade', 'status': 'active'}

# Export
print(db.export_dict())

🔮 Few hints on what's to come in future updates

• Remote mode → optional TCP listener so shadecrypt can be queried from another device (like Redis-lite networking).
• Replication/Sync → lightweight push/pull sync between devices.
• Faster query returns → implement a new algorithm to speed up query processing.
• Custom encryption algorithm → device based encryption algorithm.
• Plugin system → user-defined operations via Python modules.
