Dynamic Textarea Example

This example demonstrates the dynamic height functionality of the bubble-textarea component.

Running the Example

go run main.go

What to Try

1. Type text: Watch the textarea grow as you type
2. Add newlines: Press Enter to see hard line breaks expand the height
3. Long lines: Type very long lines to see soft wrapping in action
4. Reach the limit: Keep typing until you hit the MaxHeight (5 lines) and see scrolling take over
5. Delete content: Remove text and watch the textarea shrink back down

Key Features Demonstrated

• Dynamic height starting from 1 line
• Maximum height of 5 lines with viewport scrolling
• Debug information showing:
  • Current visual height
  • Maximum height setting
  • Hard line count (actual newlines)
  • Content length
  • Window width
• Custom prompt styling
• Border styling

Controls

• Ctrl+C or Esc: Quit the application
• Enter: Insert newline
• Backspace/Delete: Remove characters
• Standard text navigation keys work as expected
