🎨 Palette: Prevent trailing text artifacts in dynamic CLI updates#95
🎨 Palette: Prevent trailing text artifacts in dynamic CLI updates#95
Conversation
Replaced hardcoded padding spaces with the ANSI escape sequence \033[K (Erase in Line) immediately after a carriage return (\r) in src/main.cpp. This provides a cleaner and more robust dynamic terminal UI update by guaranteeing that shorter texts completely overwrite longer ones without leaving visual artifacts. Also added a journal entry in .Jules/palette.md to record this UX learning. Co-authored-by: EiJackGH <172181576+EiJackGH@users.noreply.github.com>

💡 What:
Added the ANSI escape sequence
\033[K(Erase in Line) after carriage returns (\r) in the dynamic terminal UI, replacing hardcoded padding spaces.🎯 Why:
When updating a single line in a terminal with new, shorter text, the end of the older, longer text is typically left visible unless padding spaces are used. However, padding spaces are a fragile solution, particularly when the exact length needed is variable or when dealing with smaller terminal sizes where word wrap might occur. Utilizing the
\033[Kescape sequence ensures a mathematically clean update, completely erasing any text from the cursor position to the end of the line, guaranteeing no trailing artifacts and maintaining a pristine view.📸 Before/After:
N/A (This fixes potential rendering artifacts, making dynamic strings like the countdown or score shorter/longer robust on line changes).
♿ Accessibility/UX:
Provides a much cleaner and glitch-free real-time updating experience for users interacting with the terminal application, ensuring that score and status updates are consistently legible and professionally displayed regardless of terminal width.
