Features

• Set/get/delete/list keys with optional TTL (auto-expiry)
• Save/load to JSON file
• In-memory, case-insensitive substring search
• File management: store, retrieve, delete, search, and edit files (text, JSON, CSV)
• CLI commands and Python API
• Optional persistent user/password authentication for sensitive actions
• Advanced wipe/cleanup command
• Zero external dependencies (stdlib only)

---

Installation

You can install Quickstore from PyPI or for local development.

pip install quickstore
# For local development:
pip install .

---

Quick Start

CLI

1. Set a key-value pair:

   quickstore set hello world
   

2. Retrieve the value:

   quickstore get hello
   # Output: world
   

Python

from quickstore.db import Quickstore

db = Quickstore()
db.set("hello", "world")
print(db.get("hello"))  # Output: world

---

How It Works

• Key-Value Store: Stores data as key-value pairs in a JSON file. Supports TTL (time-to-live) for auto-expiry.
• File Management: Lets you store, retrieve, delete, search, and edit files (text, JSON, CSV) with metadata tracking.
• CLI & Python API: Use all features from the command line or in your Python code.
• Authentication: Optionally protect sensitive actions (like wipe) with a username and password.
• No Dependencies: Uses only Python’s standard library.

CLI Usage

General Options

quickstore --help        # Show help for all commands
quickstore <command> --help  # Show help for a specific command
quickstore --version     # Show the installed version
quickstore -v            # Show the installed version (short flag)

Key-Value Operations

quickstore set mykey myvalue
quickstore set tempkey tempvalue --ttl 10
quickstore get mykey
quickstore list
quickstore delete mykey
quickstore search my

File Management

quickstore storefile path/to/file.txt
quickstore listfiles
quickstore getfile file.txt
quickstore deletefile file.txt
quickstore searchfiles txt

File Editing (Text, JSON, CSV only)

quickstore editfile file.txt --content "new content"
quickstore editfile file.txt --from-file path/to/newfile.txt
quickstore editfile file.txt --content "append this" --append

Security & Wipe

quickstore setpass myuser mypass      # Set DB credentials
quickstore removepass                 # Remove credentials
quickstore wipe                       # Wipe all data/files (requires auth if set)

Python API Usage

Key-Value Store

from quickstore.db import Quickstore

db = Quickstore()
db.set("foo", "bar")
print(db.get("foo"))
db.set("temp", "expire", ttl=5)
print(db.list_keys())
print(db.search("foo"))
db.delete("foo")

File Management

from quickstore.filedb import FileDB
filedb = FileDB()
filedb.store_file("test_files/test.txt")
print(filedb.list_files())
print(filedb.get_file("test.txt"))
filedb.delete_file("test.txt")
filedb.search_files("test")

File Editing (Text, JSON, CSV only)

filedb.edit_file("test.txt", content="new content")
filedb.edit_file("test.txt", from_file="newfile.txt")
filedb.edit_file("test.txt", content="append this", append=True)

Security & Wipe

filedb.setpass("myuser", "mypass")
filedb.removepass()
filedb.wipe(require_auth=False)  # Set to True to require auth if set

---

TTL (Time-to-Live) Example

from quickstore.db import Quickstore
import time

db = Quickstore()
db.set("temp", "should_expire", ttl=2)
print(db.get("temp"))  # Output: should_expire
print("Waiting...")
time.sleep(3)
print(db.get("temp"))  # Output: None (expired)

---

Example Outputs

CLI

$ quickstore set foo bar
Set foo
$ quickstore get foo
bar
$ quickstore set temp expire --ttl 2
Set temp
$ quickstore get temp
expire
$ sleep 3
$ quickstore get temp
Key not found
$ quickstore storefile test.txt
Stored file: test.txt
$ quickstore listfiles
['test.txt']
$ quickstore editfile test.txt --content "new content"
Edited file: test.txt
$ quickstore editfile test.txt --content "append this" --append
Appended to file: test.txt
$ quickstore wipe
Username: myuser
Password: mypass
Are you sure you want to wipe ALL Quickstore data and files? This cannot be undone. (yes/no): yes
Deleted quickstore.json
Deleted filemeta.json
Deleted quickstore/files directory
Database and file storage wiped.

Python

from quickstore.db import Quickstore
from quickstore.filedb import FileDB
import time

db = Quickstore()
db.set("foo", "bar")
print(db.get("foo"))  # bar
filedb = FileDB()
filedb.store_file("test.txt")
print(filedb.list_files())  # ['test.txt']
filedb.edit_file("test.txt", content="new content")
filedb.edit_file("test.txt", content="append this", append=True)
filedb.delete_file("test.txt")
filedb.setpass("myuser", "mypass")
filedb.wipe(require_auth=True)  # Prompts for username/password

Troubleshooting / FAQ

Q: Why is my key missing?

• The key may have expired if you set a TTL.
• Use quickstore list or db.list_keys() to see all current keys.

Q: Can I store images or binary files?

• Yes, but you cannot edit them in-place. Use storefile and getfile to manage them.

Q: How do I reset everything?

• Use quickstore wipe or filedb.wipe() to delete all data and files.

Q: What if I forget my password?

• Delete quickstore_auth.json manually to remove authentication (local use only).

Q: Where is my data stored?

• Key-value data: quickstore.json
• File metadata: filemeta.json
• Files: quickstore/files/

Security Notes

• Passwords are stored as SHA-256 hashes in quickstore_auth.json.
• Authentication is only required for sensitive actions (e.g., wipe) if credentials are set.
• If no credentials are set, all actions are open.
• For production-grade security, consider additional encryption or access controls.
