Usage

Here's a simple example to get you started:

import logging

import logging_bullet_train

# Set up the logger
logger = logging_bullet_train.set_logger("my_logger", level=logging.DEBUG)

# Log messages with different severity levels
logger.debug("This is a debug message")     # 🔎 DEBUG
logger.info("This is an info message")      # 💡 INFO
logger.warning("This is a warning message") # ⭐ WARNING
logger.error("This is an error message")    # 🚨 ERROR
logger.critical("This is a critical message")  # 🔥 CRITICAL
logger.log(1, "notset message")             # 🔘 UNKNOWN

Sample Output:

2024-12-21T08:08:12+00:00  🔎 DEBUG      my_logger:12  This is a debug message
2024-12-21T08:08:12+00:00  💡 INFO       my_logger:13  This is an info message
2024-12-21T08:08:12+00:00  ⭐ WARNING    my_logger:14  This is a warning message
2024-12-21T08:08:12+00:00  🚨 ERROR      my_logger:15  This is an error message
2024-12-21T08:08:12+00:00  🔥 CRITICAL   my_logger:16  This is a critical message
2024-12-21T08:08:12+00:00  🔘 UNKNOWN    my_logger:17  notset message

Advanced Configuration

Selecting an Emoji Theme

By default, the logger uses a set of emojis defined in the default theme:

• DEBUG: 🔎
• INFO: 💡
• WARNING: ⭐
• ERROR: 🚨
• CRITICAL: 🔥
• UNKNOWN: 🔘

Additional themes such as fruit, weather, and night are available in the source code. To switch themes, you can modify the formatter to use a different emoji mapping. For example:

from logging_bullet_train import level_emoji_fruit, BulletTrainFormatter, set_logger

class FruitBulletTrainFormatter(BulletTrainFormatter):
    def format(self, record):
        # Override emoji selection to use fruit theme
        level = record.levelno
        emoji = level_emoji_fruit.get(level, level_emoji_fruit[logging_bullet_train.LOGGING_UNKNOWN])
        record.levelname = f"{emoji} {record.levelname}"
        return super().format(record)

# Set up the logger with the custom formatter
logger = logging.getLogger("fruit_logger")
handler = logging.StreamHandler()
handler.setFormatter(FruitBulletTrainFormatter())
logger.addHandler(handler)
logger.setLevel(logging.DEBUG)

logger.info("This info message uses fruit emojis")

Customizing Colors and Formatting

The logger supports customization of colors and formatting. You can adjust color schemes or extend the formatter to better suit your needs by modifying the color dictionaries or overriding the BulletTrainFormatter methods.

from logging_bullet_train import set_logger, wrap_text, Fore, Back

# Set up a custom logger
custom_logger = set_logger("custom_logger", level=logging.DEBUG)

# Use custom color styling in your messages if needed
message = wrap_text("Custom styled message", fg=Fore.CYAN, bg=Back.BLACK)
custom_logger.info(message)
