Region Time Counter (ReaScript)

Region Time Counter is a minimal utility script for REAPER that displays the
total unique length of all regions in the current project.

Overlapping regions are merged, so overlapping parts are not double-counted.

Designed as a small, clean, always-on utility window.

Features

• Counts unique region time (union of all regions)
• Correct handling of overlapping regions
• Time displayed in HH:MM:SS
• Window width is fixed to 99:59:59 (no UI jumping)
• Compact, minimal UI (title + time only)
• Auto-refreshes while open
• No popups, no buttons
• No dependencies (no SWS, no js extensions)

Usage

• Launch the script to open a small floating window
• The displayed time updates automatically
• Close the window using the window close button or Esc

Notes

• The window title is intentionally empty to avoid macOS minimum titlebar width limitations.
• The visible title (“Region Time Counter”) is drawn inside the UI.
• Time is always shown in HH:MM:SS format.
