stv_utils - Python Utility Library

stv_utils is a Python utility library containing commonly used functions, particularly useful for projects requiring terminal output beautification, system environment detection, and console operations.

Features

🎨 Terminal Colors & Styles

• Generate ANSI escape codes
• Control foreground, background colors and text styles
• Includes normal and bright versions of colors

🌈 Colorized Output

• Enhanced print function supports hex color codes
• Automatically converts hex colors to the closest 256-color ANSI codes
• Maintains all parameters of native print function

🎭 Output Control

• Colorize output based on specific string prefixes
• Suppress output of specific lines by prefix
• Decorators simplify output control

🖥️ System Utilities

• Detect Chinese language environment
• Identify operating system type
• Check if running in IDLE environment
• Cross-platform console clearing function

Installation

pip install stv_utils

Quick Start

Basic Color Control

from stv_utils import color

# Get color and style dictionaries
fg, bg, styles = color()

print(f"{fg['red']}Red text{styles['reset_all']}")
print(f"{bg['blue']}Blue background{styles['reset_all']}")
print(f"{styles['bold']}Bold text{styles['reset_all']}")

Colorized Output

from stv_utils import print

# Using hex color codes
print(";#ff0000;This is red text")
print(";#00ff00;This is green text")
print(";#0000ff;This is blue text")

Output Control

from stv_utils import colorize, suppress_print

@colorize(color_code="\033[93m")  # Yellow
def my_function():
    print("|> This line will be colored")
    print("This line remains default color")

@suppress_print(start_str="|>")
def my_quiet_function():
    print("|> This line will be suppressed")
    print("This line will display normally")

System Utilities

from stv_utils import is_ch, system_check, system_clear

# Detect Chinese environment
if is_ch():
    print("Chinese environment detected")

# Get OS information
print(f"Current system: {system_check(verbose=True)}")

# Clear screen
system_clear()

Module Overview

color.py

Provides ANSI escape sequence generation:

• 8 basic colors (black, red, green, yellow, blue, magenta, cyan, white) and their bright versions
• 9 text styles (bold, dim, italic, underline, blink, reverse, hidden, strikethrough, reset_all)

output.py

Extends Python's built-in print function to support hex color codes in ;#xxxxxx; format, automatically converting to the closest 256-color ANSI code.

output_control.py

Provides output control capabilities:

• ColorizedOutput: Colorize text with specific prefixes
• SuppressedOutput: Suppress text output with specific prefixes
• colorize decorator: Simplify function output coloring
• suppress_print decorator: Simplify function output suppression

system_utils.py

System utility functions:

• is_ch(): Detect Chinese language environment
• system_check(): Get operating system information
• is_idle(): Check if running in IDLE environment
• system_clear(): Cross-platform screen clearing function
