A modular CLI pattern engine

Pytterns

One stop library for all your Terminal Patterns

With pytterns, you can make your projects pop with patterns and shapes. With this, you can print any pattern, with high customization, in any senario in the terminal. You can even make your custom Patterns through .py based pattern template system. This project has solid security and large compatibility with terminal sizes, color rendering, and OS. If you are working on a terminal project, need a loading page or you need to print shapes in any case, No need to learn each and every pattern. Just use Pytterns!

How it works

Pytterns has default patterns which can be used to get basic shapes with quite a lot of customization directly printed in the console.

You may also make your own pattern theme by making your own .py templates. Once added to Pytterns, you can use it in your code RIGHT AWAY!

Installation

To get started, you can use 2 options.

1. Download the files from git and integrate with your code.

OR

2. Download the library through pip. → Download Through PIP

Get started with Default Pytterns

Each Pyttern Pattern file which is made by me is heavily documented, so if you open it in the /patterns folder, you can get a good understanding of the args and how its processed.

Once installed, just use this to start using Pytterns in your code

from pytterns import Pytterns
pt = Pytterns()

Basic Default Args for Patterns

To make any supported shape, we use the following method to print it in the terminal:

pt.<shape name>(<size>, char=<char>, center=<Bool>, color=<color> ...)

For a simple square of side length 10:

pt.square(10)

Output:

* * * * * * * * * *
* * * * * * * * * *
* * * * * * * * * *
* * * * * * * * * *
* * * * * * * * * *
* * * * * * * * * *
* * * * * * * * * *
* * * * * * * * * *
* * * * * * * * * *
* * * * * * * * * *

Char

To make this same square with different characters, we can use the char arg.

Char takes in a String Input.

For Example, to make the above square with "x":

pt.square(10,char="x")

You get a square made with x

Center

With the center arg, we can center most of the shapes perfectly in the terminal.

Center takes a boolean input, True/False

For Example, to center the above square, we use:

pt.square(10, char="x", center=True)

Color

With the color arg, you can color your shapes with the following colors:

• red
• green
• blue
• yellow
• magenta
• cyan
• white
• reset

For example, you can color the above square like:

pt.square(10, char="x", center=True,color="red")

Hollow

With the hollow arg, you can make shapes hollow, and just get its border.

The hollow arg takes in a Boolean, True/False.

For Example, you can make a Red Centered hollow square of radius 10, made with $ like:

pt.square(10, char="$",center=True,color="red",hollow=True)

Output:

-$ $ $ $ $ $ $ $ $ $
-$                 $
-$                 $
-$                 $
-$                 $
-$                 $
-$                 $
-$                 $
-$                 $
-$ $ $ $ $ $ $ $ $ $

Terminal render would be proper and centered.

Filler

As you may have noticed in above output examples, each shape has a space (filler) between the characters. This is a space by default, but we can customize this through the filler arg.

For Example, for the above hollow square filled with Spaces, we can make it fill with - through:

pt.square(10, char="$",center=True,color="red",hollow=True, filler="-")

Output:

- $-$-$-$-$-$-$-$-$-$
- $-----------------$
- $-----------------$
- $-----------------$
- $-----------------$
- $-----------------$
- $-----------------$
- $-----------------$
- $-----------------$
- $-$-$-$-$-$-$-$-$-$

Terminal render would be proper and centered.

Other Important Args

For special shapes like Triangles or Pyramids, which could be flipped upside down, Direction and Invert can be used.

Direction:

Used to set pointing direction of a supported shape.

For Example, We can make a triangle point to 2 directions, Left and Right:

pt.triangle(10, char="*",hollow=True,filler="-",direction="left")

Output:

*-
*-*-
*- -*-
*- - -*-
*- - - -*-
*- - - - -*-
*- - - - - -*-
*- - - - - - -*-
*- - - - - - - -*-
*-*-*-*-*-*-*-*-*-*-

Invert:

With this, we can make supported shapes Upside-Down. This can be used with direction arg to gain full control of the shape's pointing.

For example, to make a left triangle inverted we use:

pt.triangle(10, char="*",hollow=True,filler="-",direction="left",invert=True)

Output:

*-*-*-*-*-*-*-*-*-*-
*- - - - - - - -*-
*- - - - - - -*-
*- - - - - -*-
*- - - - -*-
*- - - -*-
*- - -*-
*- -*-
*-*-

Custom Templates

Through templates, we can make custom patterns based on our own code, and seamlessly use it just like we did with the default code.

This may sound difficult, but we don't even need a bit of advanced programming for this.

Getting Started:

Firstly ensure Pytterns is installed in your project. Then make a folder /patterns in your project's root directory.

You can create files in this folder now, and through this you can add custom patterns to your projects.

Once you make a .py file, start with the draw() function and define the args you need for the pattern you are trying to make. Size and Center is always must to keep, rest args are based on your wish.

For Example, this is the function definition for Triangles.

def draw(size,center, char="*", filler=" ", hollow=False, direction="left", invert=False):

In this, Size (int) is the shape's size, and Center is a boolean telling if trigger has opted for centering or not.

⭐Note: If you wish to use centering in your code, you need not to make any centering system in your template file. Just make sure its compatible with our centering and you are good to go. Similarly, you also do not need to worry about colors, those get added automatically too!

After this, you can just make your pattern function, and print the output in that function itself and the Pytterns takes care of everything!

Panels

Pytterns can also make Panels. To make a Panel List, you can use the pt.panel() Function

Panels are extremely customizable. You can use the following arguments by default.

Size [int]

Horizontal Width of the Panel

Center [bool]

To horizontally center the panel in terminal

Title [str]

The Heading/Title of the panel

Content [list]

List of items to add to contents of panel

Padding [int]

Set minimum distance of text from borders

Customize Border Characters & Corners Characters

• v_border Vertical Line Characters

• h_border Horizontal Line Characters

• top_left Top Left Corner Merger Character

• top_right Top Right Corner Merger Character

• bottom_left Bottom Left Corner Merger Character

• bottom_right Bottom Right Corner Merger Character

border_bold [bool]

This makes the border characters bold, thick and bright.

center_content [bool]

This makes the content itself center within the panel's borders.

All Color args work same as they did in Shapes, and would work same in all types of patterns.

Examples for Panels.

pt.panel(
    size=80, 
    content=["Onion","Carrot","Pencils","RTX4090"],
    title="Shopping List",
    padding=2,
    border_bold=True,
    center_content=False,
    color="Magenta"
)

You may also use Colorama's editing in the content, to give each line its own color and style. The framework adapts accordingly.

Advanced Use

With pytterns, you can also make terminal animations/loading-graphics.

Eg. 1

For Example, if you want fast upward moving arrows, use this:

import time
colors=["red", "green", "yellow", "blue", "magenta", "cyan"]

while True:
    for i in range(0, 6):
        pt.triangle(i, char="-", color=colors[i], hollow=False, center=True)
        time.sleep(0.05)
    

Output:

*It would be animated due to loop, demo videos in /images folder

Eg. 2

Or, For Example you can use my favorite, the Square Loading:

import time,os
colors=["red", "green", "yellow", "blue", "magenta", "cyan"]
while True:
    for i in range(0, 6):
        pt.square(i, char="-", color=colors[i], hollow=False, center=True)
        time.sleep(0.05)
        os.system("cls" if os.name == "nt" else "clear")

For this you would need to see the video at /images folder

Eg. 3

You can use this to make a fun dynamic display of text through Panels.

import time, os
from colorama import Fore, Style

from pytterns import Pytterns
pt = Pytterns()

os.system('cls' if os.name == 'nt' else 'clear')
print("\033[?25l", end="") 

logs = [
    f"{Fore.CYAN}My code is hungry... it hasn't seen a 'Star' in weeks.",
    f"{Fore.RED}If you use 1960s Print() statements, {Style.BRIGHT}Users CRY.",
    f"{Fore.GREEN}I spent {Style.BRIGHT}3 business days {Style.NORMAL}fixing this right border.",
    f"{Fore.YELLOW}My family thinks I'm {Style.BRIGHT}studying.{Style.NORMAL} I'm actually just making {Style.BRIGHT}boxes centered.{Style.NORMAL}",
    f"{Fore.LIGHTBLUE_EX}Please use Pytterns or I'll be forced to use Light Mode.",
    f"{Fore.MAGENTA}Status: Desperately seeking validation (and a snack).",
    f"{Fore.MAGENTA}and Maybe a Break.. idk."
]

try:
    for i in range(1, len(logs) + 1):
        if i ==len(logs):
            time.sleep(4)
        print("\033[H", end="") 
        pt.panel(size=80, content=logs[:i], title="DEV-DESPERATION",padding=2,
                border_bold=True, center_content=False,color="Magenta"
        )
        time.sleep(3)
    print(f"\n{Fore.WHITE}{Style.BRIGHT}   >> Hehe hope this was fun :)")
finally:
    print("\033[?25h")
