neoprint 0.1.6

The artistic print for modern consoles.

Neoprint

A powerful alternative to Python's built-in print function with rich features for console output.

TODO(Image): Main picture showing neoprint in action.

Features

• Colored output with BBCode-style markup ([red]text[/], [bold]text[/], etc.)
• Variable names auto-detection (:n markup)
• Verbosity levels for different message types (debug, info, success, warning, error)
• Index counters for tracking sequences (:i markup)
• Timestamp support for timing operations (:t markup)
• Progress bars for long-running operations
• Pretty exception formatting with Rich library integration
• Source location display for easier debugging

Installation

pip install neoprint

Requires Python 3.9 and above.

Quick Start

Hello World

import neoprint as np

np.show('Hello, World!')
np.show('Multiple', 'arguments', 'are', 'semicolon-separated')
np.show(123, 456, 'mixed types', True, False, None)

TODO(Image): Show basic hello world output with colored text.

Print with Variable Names

import neoprint as np

name = 'Alice'
age = 30
city = 'New York'
np.show(name, age, city, ':n')

TODO(Image): Show variable names output - name = "Alice"; age = 30; city = "New York".

Highlighting and Verbosity Levels

import neoprint as np

# Basic text highlighting with BBCode
np.show('[red]error[/] [yellow]warning[/] [green]success[/]', ':r')

# Verbosity levels (:v0 to :v8)
np.show(':v1', 'DEBUG message - dim gray')
np.show(':v2', 'INFO message - cyan')
np.show(':v4', 'SUCCESS message - bright green')
np.show(':v6', 'WARNING message - bright yellow')
np.show(':v8', 'ERROR message - bright red')

# Using shorthand functions
np.debug('This is a debug message')
np.info('This is an info message')
np.success('This is a success message')
np.warning('This is a warning message')
np.error('This is an error message')

TODO(Image): Show verbosity levels and color highlighting.

Indexing

import neoprint as np

np.show(':i', 'first item')
np.show(':i', 'second item')
np.show(':i', 'third item')
np.show(':i0')  # reset counter
np.show(':i', 'counting starts over')

TODO(Image): Show indexed output with counter numbers.

Timing

import neoprint as np
from time import sleep

np.show(':t', 'starting...')
sleep(1)
np.show(':t', 'after 1 second')
sleep(2)
np.show(':t', 'after 3 seconds total')

TODO(Image): Show timing output with elapsed time.

Progress Bars

import neoprint as np
from time import sleep

# Basic progress bar
with np.Progress(total=100) as prog:
    for i in range(100):
        prog.update(f'Processing item {i + 1}')
        sleep(0.03)

# Simple iteration wrapper
items = range(50)
for item in np.progress(items):
    sleep(0.05)

TODO(Image): Record a GIF to show the progress effect.

Exception Formatting

import neoprint as np

try:
    result = 1 / 0
except ZeroDivisionError:
    np.show(':e')

TODO(Image): Show pretty exception output.

Custom Scopes

import neoprint as np

with np.scope():
    np.show(':i', 'anonymous scope - item 1')
    np.show(':i', 'anonymous scope - item 2')

with np.scope(name='MyScope'):
    np.show(':i', 'MyScope - item 1')
    np.show(':i', 'MyScope - item 2')

TODO(Image): Show scoped indexing with different scopes.

Markup Reference

Markups are short codes starting with : that modify the output behavior. They can be placed as the first or last argument.

Mark	Description
:d	Divider line
:e	Exception formatting
:i	Auto-increment index
:l	Long/expanded format (multiple lines)
:n	Show variable names
:r	Rich text/BBCode rendering
:t	Timestamp/timing
:v	Verbosity level (:v0 to :v8)

Common options:

• :d1 - thin divider, :d2 - thick divider
• :e1 - simple exception, :e2 - pretty exception (default)
• :i0 - reset all counters
• :l1 - expanded format, :l2 - special expanded (tables)
• :n0 - hide varnames, :n1 - show varnames (default)
• :r0 - disable rich, :r1 - enable rich (default)
• :v0 - trace, :v1 - debug, :v2 - info, :v4 - success, :v6 - warning, :v8 - error

For more advanced markups and detailed documentation, see markup_list.md.
