dlogger 1.0.3

Dynamic Console Logger for Python with colored output, custom icons, and other features.

DLogger

A lightweight, dynamic console logger for Python with colored output, automatic method generation, and optional timestamps.

Installation

pip install dlogger

Or just copy dlogger.py into your project.

Quick Start

from dlogger import DLogger

# Create your logger with custom icons and colors
Log = DLogger(
    icons={
        'success': 'OK',
        'error': 'ERR',
        'warning': 'WARN',
        'info': 'INFO',
    },
    styles={
        'success': 'bright_green',
        'error': 'bright_red',
        'warning': 'bright_yellow',
        'info': 'bright_cyan',
    }
)

# Use the dynamically generated methods
Log.success("Operation completed!")
Log.error("Something went wrong!")
Log.warning("Be careful!")
Log.info("Just so you know...")

Output:

[OK] Operation completed!        # in bright green
[ERR] Something went wrong!      # in bright red
[WARN] Be careful!               # in bright yellow
[INFO] Just so you know...       # in bright cyan

Timestamps (Optional)

Enable timestamps with customizable formats:

Log = DLogger(
    icons={'info': 'INFO', 'error': 'ERR'},
    styles={'info': 'bright_cyan', 'error': 'bright_red'},
    show_time=True,                      # Enable timestamps (default: False)
    time_format='%H:%M:%S',              # Customize format (default: '%H:%M:%S')
    time_style='bright_white'            # Timestamp color (default: 'bright_white')
)

Log.info("Application started")
Log.error("Connection failed")

Output:

[14:30:45] [INFO] Application started
[14:30:47] [ERR] Connection failed

Common Time Formats

• '%H:%M:%S' → 14:30:45
• '%Y-%m-%d %H:%M:%S' → 2024-03-15 14:30:45
• '%I:%M:%S %p' → 02:30:45 PM
• '%b %d %H:%M:%S' → Mar 15 14:30:45
• '%Y-%m-%d' → 2024-03-15

Custom Delimiters

Customize the brackets around icons and timestamps:

Log = DLogger(
    icons={'info': 'INFO', 'error': 'ERR'},
    styles={'info': 'bright_cyan', 'error': 'bright_red'},
    delimiters='()' # Use parentheses instead of brackets
)

Log.info("Message with parentheses")

Output:

(INFO) Message with parentheses

Available delimiter styles:

• '[]' → [INFO] (default)
• '()' → (INFO)
• '{}' → {INFO}
• '<>' → <INFO>
• '||' → |INFO|
• '--' → -INFO-

Note: Delimiters must have an even number of characters. The first half becomes the left delimiter, the second half becomes the right delimiter.

Available Colors

DLogger supports the following color styles:

Standard Colors

black, red, green, yellow, blue, magenta, cyan, white, gray

Bright Colors

bright_red, bright_green, bright_yellow, bright_blue, bright_magenta, bright_cyan, bright_white

Special Colors

orange, purple, pink

Text Styles

bold, dim, italic, underline, blink, reverse, hidden, strikethrough

Background Colors

bg_black, bg_red, bg_green, bg_yellow, bg_blue, bg_magenta, bg_cyan, bg_white, bg_gray, bg_orange, bg_purple, bg_pink

Bright Background Colors

bg_bright_red, bg_bright_green, bg_bright_yellow, bg_bright_blue, bg_bright_magenta, bg_bright_cyan, bg_bright_white

Advanced Color Options

True Color (RGB)

Use 16 million colors with RGB values:

# Create a custom RGB color
coral = Log.rgb(255, 127, 80)
Log.print("Beautiful coral text", style=coral, icon='RGB')

# Background colors
bg_color = Log.rgb(50, 50, 50, background=True)
Log.print("Text with custom background", style=bg_color, icon='BG')

# Combine with other styles
Log.print("Bold coral", style=f'bold {coral}', icon='MIX')

256-Color Palette

Access the 256-color terminal palette:

# Use 256-color codes (0-255)
orange = Log.c256(208)
Log.print("Orange text", style=orange, icon='256')

# Background colors
bg = Log.c256(234, background=True)
Log.print("Dark background", style=bg, icon='BG')

Combining Styles

Mix multiple styles together:

# Multiple styles with spaces
Log.print("Bold + Underline + Color", 
          style='bold underline bright_green', 
          icon='MIX')

# RGB with text styles
custom = Log.rgb(255, 100, 50)
Log.print("Bold custom color", style=f'bold {custom}', icon='RGB')

# Inline style definitions
Log.print("Inline RGB", style='rgb(255, 100, 50)', icon='RGB')
Log.print("Inline 256", style='c256(208)', icon='256')
Log.print("Combined", style='bold underline rgb(255,100,50)', icon='ALL')

Inline Style Formats:

• RGB: 'rgb(r,g,b)' or 'rgb(r,g,b,bg)' for background
• 256-color: 'c256(code)' or 'c256(code,bg)' for background

Additional Features

Headers and Sections

Log.header("My Application")
Log.section("Configuration")

Progress Bars

for i in range(101):
    Log.progress_bar(i, 100, prefix='Loading:', suffix='Complete')

Output:

Loading: [#####################---------] 70.0% Complete

Manual Printing

# Print without using generated methods
Log.print("Custom message", style='magenta', icon='CUSTOM')

Saving Logs to Files

DLogger can save logs to files in addition to displaying them in the console:

Single File Mode

Save all logs to a single file:

Log = DLogger(
    icons={'info': 'INFO', 'error': 'ERR', 'success': 'OK'},
    styles={'info': 'bright_cyan', 'error': 'bright_red', 'success': 'bright_green'},
    save=True,
    single_file=True,
    save_to='app.log'  # File path
)

Log.info("Application started")
Log.error("Connection failed")
Log.success("Recovered successfully")

Result: All logs saved to app.log:

[INFO] Application started
[ERR] Connection failed
[OK] Recovered successfully

Multiple Files Mode

Save logs to separate files based on their icon names:

Log = DLogger(
    icons={'info': 'INFO', 'error': 'ERR', 'success': 'OK'},
    styles={'info': 'bright_cyan', 'error': 'bright_red', 'success': 'bright_green'},
    save=True,
    single_file=False,
    save_to='./logs'  # Directory path
)

Log.info("Application started")
Log.error("Connection failed")
Log.success("Recovered successfully")

Result: Creates separate files:

• ./logs/INFO.log → [INFO] Application started
• ./logs/ERR.log → [ERR] Connection failed
• ./logs/OK.log → [OK] Recovered successfully

Save Options

Log = DLogger(
    icons={'info': 'INFO'},
    save=True,              # Enable saving (default: False)
    single_file=True,       # One file vs. multiple files (default: False)
    save_to='app.log',      # File or directory path (default: '.')
    strip_ansi=True         # Remove color codes from files (default: True)
)

Parameters:

• save: Enable or disable file saving
• single_file: If True, all logs go to one file. If False, separate files per icon
• save_to: File path (single file mode) or directory path (multiple files mode)
• strip_ansi: If True, removes color codes from saved logs for clean text files

With Timestamps

Timestamps are automatically included in saved logs when enabled:

Log = DLogger(
    icons={'info': 'INFO'},
    show_time=True,
    time_format='%Y-%m-%d %H:%M:%S',
    save=True,
    save_to='app.log'
)

Log.info("Server started")

Saved to file:

[2024-03-15 14:30:45] [INFO] Server started

How It Works

DLogger automatically generates methods based on your icons dictionary. Each key becomes a method name:

Log = DLogger(
    icons={'database': 'DB', 'api': 'API', 'cache': 'CACHE'},
    styles={'database': 'green', 'api': 'blue', 'cache': 'yellow'}
)

Log.database("Connected to PostgreSQL")  # [DB] Connected to PostgreSQL
Log.api("Request received")              # [API] Request received
Log.cache("Cache hit!")                  # [CACHE] Cache hit!

You can create any method names you want - DLogger dynamically generates them at initialization!

Complete Example

from dlogger import DLogger
import time

# Initialize with timestamps
Log = DLogger(
    icons={
        'start': '▶',
        'done': '✓',
        'fail': '✗',
        'info': 'ℹ'
    },
    styles={
        'start': 'bright_blue',
        'done': 'bright_green',
        'fail': 'bright_red',
        'info': 'bright_cyan'
    },
    show_time=True,
    time_format='%H:%M:%S',
    save=True,
    single_file=True,
    save_to='application.log'
)

Log.header("Application Startup")
Log.start("Initializing...")

Log.section("Database Connection")
Log.info("Connecting to database...")
time.sleep(1)
Log.done("Database connected successfully")

Log.section("Loading Configuration")
for i in range(101):
    Log.progress_bar(i, 100, prefix='Loading:', suffix='Complete', 
                     fill='█', style='bright_green')
    time.sleep(0.02)

Log.done("Application ready!")
# All logs are now saved to 'application.log' without color codes
