Module Completion Menu Redrawing

Problem

• After the module completion menu exits, it redraws the content in its area

• Some special colors and characters may display abnormally due to redrawing

  

Cause

• Some special colors and characters are not standard PowerShell supported
  • For example, some colors and shape characters used in Oh-My-Posh or Starship
• When getting the buffer through PowerShell methods, differences appear
• Redrawing based on these different buffers causes problems

• #49 - emoji/text rendering issue
• PowerShell#15484 - Color and Text properties not getting restored properly

Solutions

Set Height Offset

• It can make the module completion menu avoid the terminal theme area:

  psc menu config height_from_menu_bottom_to_cursor_when_above 1

  

Force Menu Below

• If you want the module completion menu to always display below, use:

  psc menu config enable_menu_show_below 1

• When the height below is not enough for the module completion menu to display below, it will scroll the buffer upward and display at the top
