Introduction

ultraprint is a Python library that extends the capabilities of the standard print function. It allows you to easily print text in different colors, styles, and backgrounds in the terminal. Additionally, it includes a logger class that can log messages with different severity levels and styles, both in the terminal and to a file.

This library is ideal for developers who want to make their terminal outputs more organized and visually appealing. With ultraprint, you can quickly identify important information, warnings, errors, and other message types based on their color and style.

Installation

To install ultraprint, simply use pip:

pip install ultraprint

Basic Usage

Color Functions

The ultraprint library provides functions to print text in various colors:

import ultraprint.common as p

p.red("This is red text")
p.green("This is green text")
p.yellow("This is yellow text")
p.blue("This is blue text")
p.purple("This is purple text")
p.cyan("This is cyan text")
p.lgray("This is light gray text")
p.dgray("This is dark gray text")

Text Style Functions

In addition to colors, you can apply styles like bold, underline, and negative:

p.bold("This is bold text")
p.underline("This is underlined text")
p.negative("This is negative text")

Background Color Functions

You can also change the background color of the text:

p.red_bg("This is red background text")
p.green_bg("This is green background text")
p.yellow_bg("This is yellow background text")
p.blue_bg("This is blue background text")
p.purple_bg("This is purple background text")
p.cyan_bg("This is cyan background text")
p.lgray_bg("This is light gray background text")
p.dgray_bg("This is dark gray background text")

Newline Function

For convenience, you can easily print new lines:

p.n()  # Prints one new line

p.n(3)  # Prints three new lines

Advanced Usage: Logging

Logger Class

The ultraprint library includes a logger class for structured logging with different severity levels, timestamped entries, and optional extra contextual information (like the file name, function, and line number). Logs can be output both to the console and to a log file.

from ultraprint.logging import logger

# Create a logger object with extra info enabled
log = logger('example_log', include_extra_info=True)

# Log some messages
log.info('This is an info message')
log.error('This is an error message')
log.warning('This is a warning message')
log.success('This is a success message')
log.debug('This is a debug message')
log.critical('This is a critical message')

Logger Methods

The logger class provides the following methods:

• info(msg): Logs an informational message (in cyan).
• error(msg): Logs an error message (in red).
• warning(msg): Logs a warning message (in yellow).
• success(msg): Logs a success message (in green).
• debug(msg): Logs a debug message (in dark gray).
• critical(msg): Logs a critical message (with a red background).

Each method writes the log entry to both the console (using colored output) and to a log file named after the logger (e.g., example_log.log).

Extra Information

The logger class allows you to include extra context, such as the filename, function name, and line number where the log message was called, using the include_extra_info=True flag. This is particularly useful for debugging.

log = logger('detailed_log', include_extra_info=True)
log.info('Logging with extra information')

This will output something like:

[2024-09-29 12:34:56] [INFO] [detailed_log] Logging with extra information [script.py:my_function:42]

Custom Filename for Logs

You can specify a custom filename for the log file by passing the filename argument when creating a logger object. If not provided, the default filename will be the name of the logger followed by .log.

log = logger('custom_logger', filename='custom_log_file.log')
log.info('This will be logged in custom_log_file.log')

Color Functions

These functions print the provided text in different colors:

• red(*args): Prints text in red.
• green(*args): Prints text in green.
• yellow(*args): Prints text in yellow.
• blue(*args): Prints text in blue.
• purple(*args): Prints text in purple.
• cyan(*args): Prints text in cyan.
• lgray(*args): Prints text in light gray.
• dgray(*args): Prints text in dark gray.

Text Style Functions

These functions apply different styles to the text:

• bold(*args): Prints bold text.
• underline(*args): Prints underlined text.
• negative(*args): Prints text with a negative style.

Background Color Functions

These functions print the provided text with different background colors:

• red_bg(*args): Prints text with a red background.
• green_bg(*args): Prints text with a green background.
• yellow_bg(*args): Prints text with a yellow background.
• blue_bg(*args): Prints text with a blue background.
• purple_bg(*args): Prints text with a purple background.
• cyan_bg(*args): Prints text with a cyan background.
• lgray_bg(*args): Prints text with a light gray background.
• dgray_bg(*args): Prints text with a dark gray background.

Logger Class

The logger class provides structured logging with timestamped entries and colored outputs. Each log method corresponds to a different severity level and prints in a specific color.

Logger Methods:

• info(msg): Logs an informational message in cyan.
• error(msg): Logs an error message in red.
• warning(msg): Logs a warning message in yellow.
• success(msg): Logs a success message in green.
• debug(msg): Logs a debug message in dark gray.
• critical(msg): Logs a critical message with a red background.

You can enable extra context (like the file name, function name, and line number) with include_extra_info=True.

Setting Log Level:

By default, the log level is set to INFO, which means that all log messages with a severity level of INFO or higher will be displayed. You can change the log level by calling the set_log_level method with one of the following options: INFO, SUCCESS, WARNING, ERROR, CRITICAL.

Setting Log File:

By default, logs are written to a file with the same name as the logger followed by .log. You can disable writing to a file by setting write_to_file=False when creating the logger object or by calling the set_write_to_file method. If you want to specify a custom filename, you can pass the filename argument when creating the logger object.

Examples

Basic Color and Style Printing

import ultraprint.common as p

p.red("This is red text")
p.bold("This is bold text")
p.red_bg("This is red background text")

Using the Logger with Extra Information

from ultraprint.logging import logger

log = logger('example_log', include_extra_info=True)
log.info('Starting the process...')
log.success('Process completed successfully!')
log.warning('This is a warning')
log.error('An error occurred')
log.critical('Critical failure, system shutting down!')
