• PyProg.spinners: The module for creating terminal spinners.
• PyProg.ntbk_progbars: The module for creating progressbars in notebooks.
• PyProg.ntbk_spinner: The moduel for creating spinners in notebook environement.
• PyProg.utils: The module providing different utilites.
• PyProg.manager: The theme and style manager.

1. PyProg.progress_bar Module

This module includes powerful classes and utilities to handle different styles of terminal progress bars:

🧱 1. ProgressBar (Class)

A flexible class for custom and advanced progress bar handling.

from PyProg.progress_bar import ProgressBar, time

pb = ProgressBar(txt_lf='Progress {percent:.0f}%: ')
total = 100

for i in range(total + 1):
    pb.update(i / total, i, total)
    time.sleep(0.1)  # Simulate work
print()  # Ensure a newline after completion

🔁 2. simple() (Function)

A lightweight wrapper generator — just like tqdm.

from PyProg.progress_bar import simple, time
from PyProg.utils import gradient_colors

iterable = range(101)
for i in simple(iterable, txt_lf='Progress {percent:.0f}%: ',
                colors = gradient_colors('#00ff00', '#0000ff', 20),
            paint = 'bar-by-bar'):
    time.sleep(0.1)  # Simulate work

• Automatically detects iterable length
• Supports optional args dictionary or keyword arguments

🧩 3. nested_bar() (Function)

Enables parent-child progress bar setups — helpful for managing parallel or dependent tasks.

from PyProg.progress_bar import ProgressBar, nested_bar, time

def task1(bar):
    for i in range(100):
        time.sleep(0.01)
        bar.update(i / 99, i + 1, 100)

def task2(bar):
    for i in range(50):
        time.sleep(0.01)
        bar.update(i / 49, i + 1, 50)

main = ProgressBar({'line': 2})
childs = {
    "Task1": [task1, {"txt_lf": "Task1 {percent:.0f}%"}],
    "Task2": [task2, {"txt_lf": "Task2 {percent:.0f}%"}]
}

nested_bar(main, childs, auto_arrangement=True)

⚠️ Important Notes on nested_bar

• If auto_arrangement=False, you must explicitly set the line for all bars.

• Never assign the same line number to multiple bars unless intentionally overlapping.

• To reserve vertical space:

  • Set child bars to line = n
  • Set parent bar to line = n + 1

2. PyProg.spinner Module

This module provides dynamic, colored, and customizable terminal spinners.

1. Spinner (Class)

Create and manage animated terminal spinners.

from PyProg.spinner import Spinner
import time

spn = Spinner({"text": "Loading", "interval": 0.1})
spn.start()

time.sleep(3)  # Simulate work

spn.stop()

Colors can cycle dynamically by using lists like ['red', 'blue', 'green']. You can use the spinner in a with block:

from PyProg.spinner import Spinner
import time

with Spinner({"text": "Please wait..."}) as spn:
    time.sleep(3)

2. spinning_work() (Function)

Runs a spinner during execution of a custom task.

from PyProg.spinner import spinning_work
import time

def task(spn):
    time.sleep(3)
    return "Done!"

spinner, result = spinning_work({"text": "Working..."}, work=task)

3. run_spinner_with_bar() (Function)

🌀 Combines a spinner with a progress bar, updating the spinner text live with bar content.

🔧 Example:

from PyProg.spinner import run_spinner_with_bar
import time

def work(pb, spn):
    for i in range(101):
        pb.update(i/100, i, 100)
        spn.text = "Working: " + pb.bar_str.replace('\r', '')
        time.sleep(0.05)

run_spinner_with_bar({}, {}, work)

🔁 Spinner Control Methods

Method	Description
start()	Begin spinner animation
stop()	Stop spinner and show final message
pause()	Pause spinner (non-terminating)
resume()	Resume paused spinner
hide()	Temporarily hide spinner output
show()	Re-show spinner if hidden

Awesome! Here's the continued documentation for the PyProg.ntbk_progbar module, picking up from your fun and expressive intro 😄:

3. PyProg.ntbk_progbar Module

Most powerful module in notebook environments! Hack-to-the-core system here! 💥

But it is so powerful because it allows you to customize progress bars via CSS — fully HTML-rendered, styleable, and beautiful 🤩.

If we were to calculate a score for customization, it would be literally ∞... (unless someone doesn’t know even the "C" of CSS 😜 — but hey, that’s not our fault 😎).

It provides these utilities:

🧱 1. NotebookProgressBar (Class)

HTML/CSS-based progress bar made for Jupyter/Colab environments. Custom colors, gradients, labels, tokens, animations — you name it!

🔧 Example Usage:

from PyProg.ntbk_progbar import NotebookProgressBar
from PyProg.utils import gradient_colors
import time

pb = NotebookProgressBar({
    'txt_lf': "Neon Progress {iters} | {percent:.0f}%",
    'txt_rt': "| ETA {eta} | Elapsed {elapsed}",
    'colors': gradient_colors('#00ff00', '#0000ff', 10) + gradient_colors('#0000ff', '#00ff00', 10),
    'paint': 'bar-by-bar',
    'length': 30,
    'text_color': ['#efa', '#afe']
})

total = 100
for i in range(total + 1):
    pb.update(i / total, current_iter=i, total_iter=total)
    time.sleep(0.03)

print("Progress Complete!")

🛠️ Customization (Arguments)

Key	Type	Description
txt_lf	str	Text on the left (supports tokens like {percent}, {iters})
txt_rt	str	Text on the right (ETA, speed etc)
bar	str or list	Character(s) to build the bar
space	str	Character for unfilled part
paint	"bar" / "bar-by-bar" / "progress-bar"	Paint strategy
colors	list[str]	List of CSS colors (or hex codes)
bar_style	str	Inline CSS for each bar block
space_style	str	CSS for empty segments
progressbar_style	str	Style for wrapper container
add_css	str	Inject your own custom CSS rules
text_color	str or list	Colors for text (left and right)
tokens	dict	Custom tokens like {spinner}, {file} etc
freq	float	Min time between updates (smoothing)

🎯 You can use it in context managers, attach HTML inline outputs, or integrate into live dashboards.

🔁 2. simple() (Function)

A quick plug-and-play generator for notebooks!

from PyProg.ntbk_progbar import simple
import time

for i in simple(range(100), txt_lf="Doing... {percent:.0f}%"):
    time.sleep(0.05)

It auto-detects len() of the iterable or uses total from arguments. Internally uses NotebookProgressBar.

🌲 3. nested_bar() (Function)

Manage multiple subtasks with individual progress bars — all under one master bar.

from PyProg.ntbk_progbar import NotebookProgressBar, nested_bar
import time

def task1(pb):
    for i in range(100):
        pb.update(i / 99, i+1, 100)
        time.sleep(0.01)

def task2(pb):
    for i in range(50):
        pb.update(i / 49, i+1, 50)
        time.sleep(0.01)

main = NotebookProgressBar({'txt_lf': "Overall Progress {percent:.0f}%"})
tasks = {
    "Task 1": [task1, {"txt_lf": "Task 1: {percent:.0f}%"}],
    "Task 2": [task2, {"txt_lf": "Task 2: {percent:.0f}%"}],
}

nested_bar(main, tasks)

🧪 Notes:

• Parent bar = outer progress
• Child bars = separate for each task
• You can customize each bar individually!

✨ Advanced Tricks

🎨 Animated Gradients:

from PyProg.utils import gradient_colors
colors = gradient_colors("#ff0000", "#0000ff", 15)

🔌 Add Custom Tokens:

NotebookProgressBar({
    'txt_lf': "📁 File: {filename} - {percent:.0f}%",
    'tokens': {
        'filename': lambda self: 'data.csv'
    }
})

🧩 Inline HTML:

bar = NotebookProgressBar({...})
some_html = f"<div>{bar.get_inline_html()}</div>"

4. PyProg.ntbk_spinner Module

⚙️ Spinner-as-a-Show — not just a spinning icon, but a complete animated display component with CSS + live-updated bar inside!

In notebooks, visual feedback during longer tasks really helps. This module takes it further by allowing:

• 🌀 Animated spinners (CSS or SVG)
• 🎨 Dynamic color cycles (background + foreground)
• 📊 Embedding progress bars directly into spinner text
• 🤝️ Full integration with NotebookProgressBar

🌀 1. NotebookDivSpinner (Class)

Create a stylish spinner that can also display dynamic text or even embed inline progress bars 😎.

✅ Example:

from PyProg.ntbk_spinner import NotebookDivSpinner
import time

spn = NotebookDivSpinner({
    "text": "Processing",
    "fg_text": ["#00ff00", "#00ccff"],
    "bg_text": ["transparent", "#222"],
    "clr_interval": [0.5, 0.5]
})

spn.start()
time.sleep(3)
spn.stop()

.hide() / .show()	Hide or reveal the spinner
.pause() / .resume()	Stop animation loop or resume it
.set_text("New...")	Live update the text next to spinner

🔗 2. run_spin_with_bar() (Function)

Attach a spinner ☸ and embed a progress bar 📈 directly into it as live updating text!

from PyProg.ntbk_spinner import run_spin_with_bar
import time

def work(pb, spn):
    for i in range(101):
        pb.update(i/100, i, 100)
        spn.set_text(pb.get_inline_html())  # Embed bar into spinner text
        time.sleep(0.025)

run_spin_with_bar({}, {}, work)

🔄 Parameters

Param	Description
spinner_args	Dict for spinner customization
bar_args	Dict for progress bar styling
work	A function of (pb, spn) where progress and text are updated

🔁 Returns

(pb, spn)  # ProgressBar instance, Spinner instance

You can use them later if needed!

🧪 Pro Tip:

You can embed inline progress bar segments inside the spinner like this:

spn.set_text(pb.get_inline_html())

Or display custom values or tokenized stats if you set bar_args['txt_lf'].
