ltoolboxLib 1.1.2

Python utilities for dynamic strings, sandboxed files, multiuse-case classes, and ANSI colors

ltoolboxLib

A Swiss Army knife for Python scripting and automation

ltoolboxLib is a powerful utility library for Python that simplifies file operations, text manipulation, encoding, system tasks, and more, with built-in sandbox mode for safe testing.

Features

• File Operations - Read, write, copy, grep, and manage files (with sandbox support).
• Dynamic Strings - S() and M() for runtime string interpolation.
• Encoding/Decoding - Secure encode()/decode() with shadow keys.
• System Utilities - Cross-platform notifications, clipboard access, and public IP fetching.
• ANSI Styling - RGB colors and text formatting for terminals.
• Sandbox Mode - Virtual filesystem for testing without touching real files.
• Smart Functions - Fuzzy matching, random generators, UUIDs, and more.
• Temporary Variables - Values that expire over time, after use, or permanently transform.
• Debugging Tools - Tracebacks, watches, pauses, and safe evaluations.
• Utility Classes - Including Toggle, Undo, and Lock for stateful logic and memory control.

Quick Start

1. File Operations (Sandbox Supported)

from ltoolboxLib import *

debug.sandbox(True)
rw_file("test.txt", "Hello, sandbox!")
print(file_exists("test.txt"))  # True (in sandbox)

debug.sandbox(False)
rw_file("real_file.txt", "This writes to disk.")

1-B. JSON

data = rwe_json("config.json") # Returns full JSON
rwe_json("config.json", {"a": {"b": 2}}) # Sets entire JSON
print(rwe_json("config.json", E="a/b"))  # Returns a nested value (ie. a: {b: 2})
rwe_json("config.json", 42, E="x/y/z") # Sets that nested value (ie. x: {y: {z: 42}})

2. Dynamic Strings (S and M)

user = "Alice"
id_num = 42

greeting = S("User {user} (ID: {id_num}) logged in at {timestamp()}")
m_greeting = M("User {user} (ID: [id_num]) logged in at {timestamp()}")

user = "Bob"
id_num = 99

print(greeting)     # User Bob (ID: 99) ...
print(m_greeting)   # User Bob (ID: 42) ...

3. Encoding & Security

encoded = encode("Secret Message")
decoded = decode(encoded)
print(decoded.decode())

4. System Utilities

notify("Done!", "Script complete!")
clipboard_copy("Text copied.")
print(censor(get_public_ip(), '-'))  # "118.---.---.93"

5. Temporary Variables

t = Temporary("Code: 1337", delay=5, expiry="Expired")
print(t)  # "Code: 1337"
time.sleep(5)
print(t)  # "Expired"

t2 = Temporary("Limited use", uses=2, expiry="Gone")
print(t2)  # "Limited use"
print(t2)  # "Limited use"
print(t2)  # "Gone"

6. Other Classes

Toggle("A", "B", "C")  # Cycles through values
Undo("Initial").set("Change 1").undo()  # Reverts
Lock("Secret").lock().set("Still secret")  # Cannot overwrite if locked
