vb-console 1.0.0

Logger and object inspector for Python

vb-console

A custom Python object inspector with a fancy style.

Installation

$ pip install vb-console

By default, console output is disabled. You can enable output via

• setting ENABLE_CONSOLE environment variable
• passing enabled=True keyword argument

Usage

Let’s try with-in the python repl:

$ ENABLE_CONSOLE=1 python

then;

Python 3.8.5 (default, Nov 17 2020, 17:58:11) 
[Clang 12.0.0 (clang-1200.0.32.27)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from console import console
>>> console = console(source='repl', enabled=True)
>>> console('hello', 'world')
('hello', 'world')
>>> 

This usage above is always better choice. Helps you to keep out un-wanted outputs in the production environment!

Let’s try with enabled=True;

$ python

then;

Python 3.8.5 (default, Nov 17 2020, 17:58:11) 
[Clang 12.0.0 (clang-1200.0.32.27)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from console import console
>>> console = console(source='repl', enabled=True)
>>> console.dir([1,2])
{   'internal_methods': [   '__add__', '__class__', '__contains__', '__delattr__', '__delitem__', '__dir__', '__doc__', '__eq__',
                            '__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__iadd__', '__imul__',
                            '__init__', '__init_subclass__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__',
                            '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__reversed__', '__rmul__', '__setattr__',
                            '__setitem__', '__sizeof__', '__str__', '__subclasshook__'],
    'public_attributes': ['append', 'clear', 'copy', 'count', 'extend', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort']}
>>> 

In this mode, console will always be available. Here is a quick usage with Django:

from django.conf import settings
from console import console

console = console(source='repl', enabled=settings.DEBUG)  # will be disabled in production!

You have few options for console output:

• console(object)
• console(object, object, object, ...)
• console.dir(object)

All you need is this piece of code:

# import area
from console import console

console = console(source=__name__, enabled=True)

console('hello', 'world')
console.dir([])

Here is an example class:

class MyClass:
    """Example class"""

    klass_var1 = 1
    klass_var2 = 2
    klass_var3 = 'string'
    klass_var4 = list()
    klass_var5 = dict()
    klass_var6 = set()

    def __init__(self):
        self.name = 'Name'

    def get_name_and_method(self):
        return self.name + ' get_name_and_method'

    def _private_method(self):
        return self.name + ' _private_method'

    @property
    def admin(self):
        return True

    @staticmethod
    def statik():
        return 'Static'

    @classmethod
    def klass_method(cls):
        return 'kls'

my_class_instance = MyClass()
console.dir(my_class_instance)

outputs:

{   'class_methods': ['klass_method'],
    'class_variables': ['klass_var1', 'klass_var2', 'klass_var3', 'klass_var4', 'klass_var5', 'klass_var6'],
    'data_attributes': ['name'],
    'internal_methods': [   '__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__',
                            '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__',
                            '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__',
                            '__str__', '__subclasshook__', '__weakref__'],
    'methods': ['get_name_and_method'],
    'private_methods': ['_private_method'],
    'properties': ['admin'],
    'public_attributes': [   'admin', 'get_name_and_method', 'klass_method', 'klass_var1', 'klass_var2', 'klass_var3', 'klass_var4',
                             'klass_var5', 'klass_var6', 'name', 'statik'],
    'static_methods': ['statik']}

Now, let’s disable basic output:

from console import console
console = console(source=__name__, enabled=True, basic=False)

outputs with header and footer. source gets it’s value from __name__ and currently the value is set to __main__:

[__main__ : instance of MyClass | <class '__main__.MyClass'>].........................................................................
{   'class_methods': ['klass_method'],
    'class_variables': ['klass_var1', 'klass_var2', 'klass_var3', 'klass_var4', 'klass_var5', 'klass_var6'],
    'data_attributes': ['name'],
    'internal_methods': [   '__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__',
                            '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__',
                            '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__',
                            '__str__', '__subclasshook__', '__weakref__'],
    'methods': ['get_name_and_method'],
    'private_methods': ['_private_method'],
    'properties': ['admin'],
    'public_attributes': [   'admin', 'get_name_and_method', 'klass_method', 'klass_var1', 'klass_var2', 'klass_var3', 'klass_var4',
                             'klass_var5', 'klass_var6', 'name', 'statik'],
    'static_methods': ['statik']}
......................................................................................................................................

Options

• source: Name of the header if the basic option is set to False. It’s good idea to set to __name__
• indent: Indentation value, default is: 4
• width: Output’s width. Default is set to Terminal’s current width.
• enabled: Default is False. Can be modified via ENABLE_CONSOLE env-var or setting this arg to True
• seperator_char: Default is: .
• colored: Default is False. Set this to True for colored output
• dir_colors: This is a dict, default is dict(keys='yellow', values='default')
• header_color: Default is green
• footer_color: Default is green
• basic: Default is True. In basic mode, header and footer are not available
• writer: Default is sys.stdout

Valid colors are: black, red, green, yellow, blue, magenta, cyan, white and default

Development

I’ve prepared few rake tasks:

$ rake -T

rake build           # Build package
rake bump[revision]  # Bump version
rake clean           # Remove/Delete build..
rake default         # Default task => :install
rake install         # Install package for local development purpose
rake test            # Run test
rake upload:main     # Upload package to main distro (release)
rake upload:test     # Upload package to test distro

Default rake task installs package locally for development purposes:

$ rake       # runs rake install
