Installation

pip install pigmento

Quick Start

from pigmento import pnt

class Test:
    @classmethod
    def class_method(cls):
        pnt('Hello World')

    def instance_method(self):
        pnt('Hello World')

    @staticmethod
    def static_method():
        pnt('Hello World')
        

def global_function():
    pnt('Hello World')

Test.class_method()
Test().instance_method()
Test.static_method()
global_function()

|Test| (class_method) Hello World
|Test| (instance_method) Hello World
|Test| (static_method) Hello World
(global_function) Hello World

Style Customization

from pigmento import pnt, Color

pnt.set_display_style(
    method_color=Color.RED,
    method_bracket=('<', '>'),
    class_color=Color.BLUE,
    class_bracket=('[', ']'),
)

Test.class_method()
Test().instance_method()
Test.static_method()

[Test] <class_method> Hello World
[Test] <instance_method> Hello World
[Test] <static_method> Hello World

Display Mode Customization

from pigmento import pnt

pnt.set_display_mode(
    display_method_name=False,
)

Test.class_method()

|Test| Hello World

Prefixes

Pigmento supports customized prefixes for each print. It is important to note that all prefixes are in first-in-first-print order.

from pigmento import pnt, Prefix, Color, Bracket

pnt.add_prefix(Prefix('DEBUG', bracket=Bracket.DEFAULT, color=Color.GREEN))

global_function()

[DEBUG] (global_function) Hello World

Dynamic Prefix

Texts inside prefix can be dynamically generated.

from pigmento import pnt, Prefix, Color, Bracket

class System:
    STATUS = 'TRAINING'
    
    @classmethod
    def get_status(cls):
        return cls.STATUS
    
    
pnt.add_prefix(Prefix(System.get_status, bracket=Bracket.DEFAULT, color=Color.GREEN))

global_function()
System.STATUS = 'TESTING'
global_function()

[TRAINING] (global_function) Hello World
[TESTING] (global_function) Hello World

Build-in Time Prefix

TimePrefix is a build-in prefix that can be used to display time.

import time
import pigmento
from pigmento import pnt

pigmento.add_time_prefix()

Test.class_method()
time.sleep(1)
Test.class_method()

[00:00:00] |Test| (class_method) Hello World
[00:00:01] |Test| (class_method) Hello World

Plugins

Pigmento supports plugins to extend its functionalities.

Build-in Logger

Everytime you print something, it will be logged to a file.

import pigmento
from pigmento import pnt

pigmento.add_log_plugin('log.txt')

global_function()

(global_function) Hello World

The log file will be created in the current working directory and the content will be removed the color codes.

cat log.txt

[00:00:00] (global_function) Hello World

Build-in Dynamic Color

DynamicColor will map caller class names to colors.

import pigmento
from pigmento import pnt


class A:
    @staticmethod
    def print():
        pnt(f'Hello from A')


class B:
    @staticmethod
    def print():
        pnt(f'Hello from B')


class D:
    @staticmethod
    def print():
        pnt(f'Hello from C')


A().print()
B().print()
D().print()

pigmento.add_dynamic_color_plugin()

A().print()
B().print()
D().print()

|A| (print) Hello from A
|B| (print) Hello from B
|D| (print) Hello from C
|A| (print) Hello from A
|B| (print) Hello from B
|D| (print) Hello from C

Plugin Customization

from pigmento import pnt, BasePlugin


class RenamePlugin(BasePlugin):
    def middleware_before_class_prefix(self, name, bracket, color):
        return name.lower(), bracket, color

    def middleware_before_method_prefix(self, name, bracket, color):
        return name.replace('_', '-'), bracket, color


pnt.add_plugin(RenamePlugin())

Test.class_method()
Test().instance_method()
Test.static_method()

|test| (class-method) Hello World
|test| (instance-method) Hello World
|test| (static-method) Hello World

Multiple Printers

Pigmento supports multiple printers.

from pigmento import Pigmento, Bracket, Color, Prefix

debug = Pigmento()
debug.add_prefix(Prefix('DEBUG', bracket=Bracket.DEFAULT, color=Color.GREEN))

info = Pigmento()
info.add_prefix(Prefix('INFO', bracket=Bracket.DEFAULT, color=Color.BLUE))

error = Pigmento()
error.add_prefix(Prefix('ERROR', bracket=Bracket.DEFAULT, color=Color.RED))


def divide(a, b):
    if not isinstance(a, int) or not isinstance(b, int):
        error('Inputs must be integers')
        return

    if b == 0:
        debug('Cannot divide by zero')
        return

    info(f'{a} / {b} = {a / b}')


divide(1, 2)
divide(1, 0)
divide('x', 'y')

[INFO] (divide) 1 / 2 = 0.5
[DEBUG] (divide) Cannot divide by zero
[ERROR] (divide) Inputs must be integers
