Forever Scalable

Neuraldig is a Python based toolkit for writing Command-Line Interface(CLI) applications. Quo is making headway towards composing speedy and orderly CLI applications while forestalling any disappointments brought about by the failure to execute a CLI API. Simple to code, easy to learn, and does not come with needless baggage.

Compatibility

Neuraldig works flawlessly with Linux, OSX, and Windows. Neuraldig requires Python 3.8 or later.

Features

• Support for Ansi, RGB and Hex color models
• Support for tabular presentation of data
• Intuitive progressbars
• Code completions
• Nesting of commands
• Customizable Text User Interface (TUI) dialogs.
• Automatic help page generation
• Syntax highlighting
• Autosuggestions
• Key Binders

Getting Started

Installation

You can install quo via the Python Package Index (PyPI)

pip install -U quo

Run the following to test Quo output on your terminal:

python -m quo

Quo echo

To output formatted text to your terminal you can import the echo method. Try this:

Example 1

 from quo import echo

 echo(f"Hello, World!", fg="red", italic=True, bold=True))

Example 2

 from quo import echo

 echo(f"Quo is ", nl=False)
 echo(f"scalable", bg="red", fg="black") 

Alternatively, you can import print

 from quo import print
 from quo.text import Text

 print(Text('<b>This is bold</b>'))
 print(Text('<i>This is italic</i>'))
 print(Text('<u>This is underlined</u>'))                        
 # Colors from the ANSI palette.
 print(Text('<red>This is red</red>'))
 print(Text('<style fg="green" bg="red">Green on red background</stlye>'))

Quo prompt

• Using quo.prompt method.

 from quo import prompt

 prompt("What is your name?")

• Using quo.prompt.Prompt object

 from quo.prompt import Prompt
   
 session = Prompt()
 session.prompt("Type something:")

Quo Library

Quo contains a number of builtin features you can use to create elegant output in your CLI.

Click the following headings for details:»

Console

For more control over quo terminal content, import and construct a `Console` object.

   
  from quo import Console

  console = Console()

Launching Applications

Quo supports launching applications through Console.launch. This can be used to open the default application associated with a URL or filetype.

 from quo import Console
   
 console = Console()
 console.launch("https://quo.rtfd.io/")

Completion

Autocompletion

Press [Tab] to autocomplete

 from quo.prompt import Prompt
 from quo.completion import WordCompleter
 example = WordCompleter(['USA', 'UK', 'Canada', 'Kenya'])
 session = Prompt(completer=example)
 session.prompt('Which country are you from?: ')

Autosuggestion

Auto suggestion is a way to propose some input completions to the user. Usually, the input is compared to the history and when there is another entry starting with the given text, the completion will be shown as gray text behind the current input. Pressing the right arrow → or ctrl-e will insert this suggestion, alt-f willinsert the first word of the suggestion.

 from quo.prompt import Prompt
 from quo.completion import AutoSuggestFromHistory
 from quo.history import InMemoryHistory

 history = InMemoryHistory(
 history.append("import os")
 history.append('print("hello")') 
 history.append('print("world")')  
 history.append("import path"

 session = Prompt(auto_suggest=AutoSuggestFromHistory(), history=history)

 while True:
    session.prompt('> ')

Documenting Scripts

Quo automatically generates help pages for your command-line tools.

 from quo import print
 from quo.console import command
 from quo.console import app

 @command()
 @app('--count', default=1, help='number of greetings')
 @app('--name', prompt="What is your name?", help="The person to greet")

def hello(count: int, name: str):
    """This script prints hello NAME COUNT times."""
       for x in range(count):
           print(f"Hello {name}!")

 if __name__ == "__main__:
          hello()

And what it looks like:

Progress

Creating a new progress bar can be done by calling the class **ProgressBar** The progress can be displayed for any iterable. This works by wrapping the iterable (like ``range``) with the class **ProgressBar**

 import time
 from quo.progress import ProgressBar
  
 with ProgressBar() as pb:
               for i in pb(range(800)):
                             time.sleep(.01)

Key Binding

A key binding is an association between a physical key on a keyboard and a parameter.

  
 from quo import echo
 from quo.prompt import Prompt
 from quo.keys import Bind
 
 bind = Bind()
 # Print "Hello world" when ctrl-h is pressed
 @bind.add("ctrl-h")
 def _(event):
     echo("Hello, World!")
 session.prompt(">>", bind=bind)

Dialog

High level API for displaying dialog boxes to the user for informational purposes, or get input fromthe user.

1. Example of a message box dialog.

 from quo.dialog import MessageBox

 MessageBox(
         title="Message pop up window",
         text="Do you want to continue?\nPress ENTER to quit.").run()                                       

The above produces the following output

2. Example of a prompt box dialog

 from quo.dialog import PromptBox

 PromptBox(
           title="PromptBox shenanigans",
           text="What Country are you from?:").run()

Read more on Dialogs

Table

Function Table offers a number of configuration options to set the look and feel of the table, including how borders are rendered and the style and alignment of the columns.

Example

 from quo import echo
 from quo.table import Table

 data = [
   ["Name", "Gender", "Age"],
   ["Alice", "F", 24],
   ["Bob", "M", 19],
   ["Dave", "M", 24]
 ]
 echo(Table(data))

Widgets

A collection of reusable components for building full screen applications.

Label

Widget that displays the given text. It is not editable or focusable.

 from quo.console import Console
 from quo.keys import Bind
 from quo.layout import Layout
 from quo.widget import Label

 root = Label("Hello, World", style="fg:black bg:red")
  
 layout = Layout(root)
  
 # Ctrl-c to exit
 bind = Bind()
  
 @bind.add("ctrl-c")
 def _(event):
    event.app.exit()

 Console(
     layout=layout,
     bind=bind,
     full_screen=True).run()
