Closes #33945. Here's my attempt to describe what's going on in that issue and what this fix is doing: We always render the terminal inline assistant starting on the line after the cursor, with a height of 4 lines. When deploying it, we scroll the viewport to the bottom of the terminal so that the assistant will be in view. When scrolling while the assistant is deployed (including in that case), we need to make an adjustment that "pushes up" the terminal content by the height of the assistant, so that we can scroll to see all the normal content plus the assistant itself. That quantity is `scroll_top`, which represents _how much height in the current viewport is occupied by the assistant that would otherwise be occupied by terminal content_. So when you scroll up and a line of the assistant's height goes out of view, `scroll_top` decreases by 1, etc. When we scroll to the bottom after deploying the assistant, we set `scroll_top` to the result of calling `max_scroll_top`, which computes it this way: ``` block.height.saturating_sub(viewport_lines.saturating_sub(terminal_lines)) ``` Which, being interpreted, is "the height of the assistant, minus any viewport lines that are not occupied by terminal content", i.e. the assistant is allowed to eat up vertical space below the last line of terminal content without increasing `scroll_top`. The problem comes when we clear the screen---this adds a full screen to `terminal_lines`, but the cursor is positioned at the top of the viewport with blank lines below, just like at the beginning of a session when `terminal_lines == 1`. Those blank lines should be available to the assistant, but the `scroll_top` calculation doesn't reflect that. I've tried to fix this by basing the `max_scroll_top` calculation on the position of the cursor instead of the raw `terminal_lines` value. There was also a special case for `viewport_lines == terminal_lines` that I think can now be removed. Release Notes: - Fixed the positioning of the terminal inline assistant when it's deployed after clearing the terminal. |
