🔢 NumpyGui Update Patch Notes

---

🔖 Version Comparison

Feature	🏛️ Previous Version	🚀 Updated Version
Architecture	Long if-elif chains	Dictionary Dispatching (Clean & Fast)
Theme Engine	Static / Buggy	Dynamic Tracking (Glitch-free switching)
Input Engine	1D Lists (Flattened)	2D Matrices (Multi-line Detection)
UI Theme	Mixed (Native + Custom)	Fully Consistent (CTkToplevel)
Feedback	Console Prints	In-App Status Bar (Color-coded)
Stability	Prone to crashes	Global Error Handling

---

✨ Detailed Changes

🛠️ 1. Core Architecture & Optimization

• Dictionary Dispatching: Replaced repetitive if-elif blocks with dictionary mappings for Arithmetic, Trigonometry, Statistics, and UI generation. This significantly reduces code complexity and improves performance.
• Dynamic Widget Tracking: Implemented a robust system to track UI elements. Widgets are registered in optimized batches, ensuring that theme changes (Light/Dark) apply instantly and correctly to every button and label, fixing previous visual glitches.
• Smart Input Parsing: The turn_into_array engine was rewritten. It now detects newlines to construct 2D Numpy Arrays, enabling true matrix operations instead of flattening everything into a list.
• Safety Pipeline: All mathematical operations are now wrapped in try-except blocks. Invalid inputs trigger a UI warning instead of crashing the application.

🎨 2. User Interface (UI/UX)

• Enhanced Night Mode: Fixed issues where tab labels and button edges would remain in the wrong color state. The new theme engine recursively updates all nested widgets.
• Consistent Theming: All popup windows—Results, Size Filter, Parity Filter, Search—now use CTkToplevel. They automatically inherit the user's Dark/Light theme preference.
• Visual Clarity: Added "Array A" and "Array B" labels to the input fields, eliminating confusion during binary operations.
• Status Bar: A new status label at the bottom of the screen provides immediate feedback (e.g., "Calculated Sin" or "Invalid Input").

🚀 3. Functional Enhancements

• Matrix Support: Full support for 2D array inputs. Operations like Get shape now return (rows, columns) correctly.
• Fixed "Mode" Statistic: The previous version incorrectly used numpy.mod (remainder) for the "Mode" button, causing crashes. The update now safely implements scipy.stats.mode with a fallback check.
• Dual Clipboard Export:
  • "Copy Array": Copies the formatted Numpy string (e.g., [1 2 3]).
  • "Copy Numbers": Restored the ability to copy raw, space-separated numbers (e.g., 1 2 3), optimized for pasting into Excel.

This update transforms NumpyGui from a menu-driven, single-window application into a modern, dual-pane interface with persistent state management. It introduces a tabbed operations panel, inline controls for complex functions, and significantly refactors the codebase for maintainability and stability.

---

🚀 New Features

💾 Persistent State Management

• New StateManager Class: Implemented to handle saving and loading settings via numpygui_state.json.
• Persisted Settings:
  • Theme: Remembers "Light" vs "Dark" mode preference across restarts.
  • View Configuration: Remembers the visibility state of the Operations Tabs and Menu Bar.

🗂️ Tabbed Operations Interface

• Side Panel: Added a CTkTabview on the right side of the window, organizing operations into 10 distinct categories (Arithmetic, Rounding, Trig, Stats, etc.).
• Dynamic Resizing:
  • Compact Mode: Width 725px (Tabs hidden).
  • Expanded Mode: Width 1050px (Tabs visible).
• View Control: Added a View menu to toggle the Side Tabs and Top Menus independently.

🧮 Calculator Grid (Arithmetic Tab)

• Visual Update: Replaced the list of text-based arithmetic commands with a Calculator-style Grid.
• Symbols: Uses mathematical symbols (+, -, ×, ÷, x², √, |x|) for faster recognition.

---

🛠️ Functional Overhaul: Inline Controls

Many operations that previously required popup windows (CTkToplevel) or lacked parameter inputs have been upgraded to use Inline Controls directly within the tabs.

Feature	Old Behavior	New Behavior
Data Filtering	Opened a popup window for "Size" and "Parity".	Inline: CTkEntry for threshold, CTkSegmentedButton for >/< and Even/Odd.
Search	Opened a popup window.	Inline: CTkEntry to input search value + "Find" button.
Linspace	Called linspace(array) (often incorrect usage).	Inline Generator: Inputs for Start, Stop, and Count.
Random Int	Used array data as bounds.	Inline Generator: Inputs for Min, Max, and Count.
Rounding	Always rounded to integer.	Precision Control: Added input for Decimal Places.
Log/Power	Standard bases only ($e, 10, 2$).	Custom Base: Added input to calculate $log_b(x)$ or $b^x$.
Constants	Menu items inserted values.	Dropdown: CTkOptionMenu to select constant + "Insert" button.
Num Systems	Separate menu items.	Selector: CTkSegmentedButton (Bin/Oct/Hex) + Convert button.

---

🎨 UI/UX Improvements

Layout & Styling

• Grid System: Migrated main layout from pack() to grid() to support the split-pane design.
• Input Frame: Grouped the two main input textboxes into a transparent input_frame for better alignment.
• Widget Upgrade: Replaced standard tkinter.Text with customtkinter.CTkTextbox.
  • Note: Explicitly enabled undo=True on the underlying widget to maintain previous functionality.

Grouping

• Trigonometry: Functions are now visually grouped: Standard, Conversion, Hyperbolic, Inverse Hyperbolic.
• Statistics: Grouped into Central Tendency, Extremes, and Dispersion.

---

💻 Code Refactoring & Quality

Architecture

• Modular Construction: The __init__ method was monolithic. It has been refactored into specific helper methods for each tab:
  • create_arithmetic_widgets
  • create_data_widgets
  • create_calculus_widgets
  • (and others...)
• Centralized Config: A self.tabs dictionary now defines the structure of both the Tabs and the Menus, ensuring they stay in sync.

Logic & Stability

• Input Safety: Added try-except blocks in turn_into_array and all inline operation methods.
  • Fix: Prevents the app from crashing if the user enters non-numeric text.
• Theme Logic: Refactored themes() into set_theme() and toggle_theme().
  • Improvement: Relies more on customtkinter's native theming rather than manually configuring widget colors line-by-line.
• Random Generator Fix: Updated generate_op_num to correctly format list data as a space-separated string before inserting it into the text box (' '.join(map(str, ...))).

Imports

• Added json and os to support the new StateManager.

---

🐛 Bug Fixes

• Result Window Centering: Improved the math used to center the result popup window on the screen.
• Copy Error Handling: Added safety checks when copying results to the clipboard to prevent errors if the result format is unexpected.

V0.27 - EgonDV, Refactor & QOL ✨

Patch Notes: EgonDV Refactoring & QOL Update

🚀 Major Updates

1. Architecture Refactoring (OOP)

• New Base Class (BasePlotMaker):
  • Introduced BasePlotMaker inheriting from customtkinter.CTk.
  • Centralized window initialization logic (title, geometry, resize behavior).
  • Centralized protocol handling (WM_DELETE_WINDOW) and window tracking (opened_programs list).
  • Added finalize_setup() method to handle common finalization tasks like centering the window (place_w_middle) and initializing "Fun Numbers".
• Inheritance Update:
  • All specific graph maker classes (GraphMaker, BarMaker, BoxPlot, etc.) now inherit from BasePlotMaker instead of directly from customtkinter.CTk.
  • Removed redundant __init__ boilerplate code across all classes.

2. User Interface Redesign (Tabs)

• Tabbed Navigation:
  • Replaced monolithic grid layouts with customtkinter.CTkTabview for most tools.
  • Controls are now organized into logical categories (e.g., Data, Style, Options, Legend) to reduce window clutter and improve usability.
• Layout Improvements:
  • Standardized grid layouts within tabs using sticky='ew' for better responsiveness.

3. Enhanced Data Import

• Advanced CSV Upload:
  • Replaced the generic upload() function with a robust ask_for_file() and ask_for_columns() workflow.
  • Column Selector: When uploading a CSV, a new popup window allows users to select specific columns to map to input fields, rather than dumping the entire file content into a single entry.
