Safety-first Python desktop text editor
PyTextEditor
PyTextEditor is a modern desktop text editor engineered in Python with Tkinter, focusing on data safety, file integrity, and daily productivity. It implements atomic file writing to prevent data corruption during unexpected crashes or power loss, alongside automatic background saving with on-launch crash recovery. The editor provides BOM-aware encoding detection with explicit character set selection upon saving, robust regex-powered find and replace with live match navigation, theme customization (light/dark modes), line/column indicators, recent files tracking, and a clean CLI packaging entrypoint.

Problem
Basic text editors often lack vital data-safety mechanisms like atomic writes, crash recovery, and multi-encoding detection, putting uncommitted work at risk during unexpected system interruptions.
Solution
PyTextEditor combines zero-dependency Tkinter UI architecture with production-grade file handling, crash recovery buffers, atomic file overwrites, and configurable interface themes.
Outcome
A dependable, lightweight desktop productivity application that showcases Python desktop software engineering, robust file I/O safety patterns, and comprehensive unit-tested architecture.
