Terminapy

Terminapy is a lightweight Python library for creating a simple ASCII/Unicode-based terminal "screen" with sub-screens. It allows you to divide the terminal into multiple panels, each managed independently, and safely share screens between threads.

What Is It For?

Terminapy provides a Screen class that help you create and manage a display of the terminal:

╭───────────────────────┬───────────────────────╮
│                       │                       │
│                       │                       │
│      Sub-Screen 1     │     Sub-Screen 2      │
│   (displaying text)   │  (displaying text 2)  │
│                       │                       │
│                       │                       │
╰───────────────────────┴───────────────────────╯

the lib provide function to print directly the screen on the terminal but you can get the screen as a str and display it on you own there will be some example

External Lib use:

In this lib i will try to use as little as possible external lib

• os
• math
• time
• threading

Installation

pip install terminapy

Usage Examples

Simple loop

import terminapy as tp

screen = tp.screen()
while True:
    screen.draw_terminal_screen()

Split vertically

import terminapy as tp

screen = tp.screen()
screen.split_vertical(0.5)
while True:
    screen.draw_terminal_screen()

Updating content

import terminapy as tp
import time

screen = tp.screen()
screen.split_vertical(0.5)
left = screen.get_screen(0)
right = screen.get_screen(1)

left.append("Left panel: Hello!")
right.append("Right panel: Counter")

counter = 0
while True:
    counter += 1
    right.rewrite_last_line(f"Right panel: {counter}")
    screen.draw_terminal_screen()
    time.sleep(1)

Threading Example

import terminapy as tp
import threading
import time

def worker(sub):
    for i in range(20):
        sub.append(f"Thread says {i}")
        time.sleep(0.5)

screen = tp.screen()
screen.split_vertical(0.5)
left = screen.get_screen(0)
right = screen.get_screen(1)

t = threading.Thread(target=worker, args=(right,))
t.start()

for _ in range(40):
    screen.draw_terminal_screen()
    time.sleep(0.25)
t.join()

split_horizontally(ratio: float)	Split top/bottom
split_vertically(ratio: float)	Split left/right
change_line(lines:list[str],copy:bool = True)	Replace all the previous lines by the new line
append(message: str)	Append text to sub-screen
clear()	Clear a screen
rewrite_last_line(message: str)	Replace last line
get_screen(index: int)	Get a sub-screen
get_terminal_screen()	Get the str of the screen (what is use in draw_terminal_screen)
draw_terminal_screen()	Render terminal screen
full_autonome(refresh_rate : float)	Start a thread and refresh the terminal on it's own you do not need to have a loop do draw the screen on the terminal
