Enum PopupPlacement 

pub enum PopupPlacement {
    CursorAnchored,
    Centered,
    MinibufferBand,
}

Where the popup overlay anchors on screen.

Cursor-anchored popups (hover, signature help, diagnostic-at- cursor) sit adjacent to the symbol that triggered them so the user’s eye doesn’t have to leave the cursor to read them. Centred popups are command-launched and unrelated to where the cursor happens to be (:lsp-status, :describe-*, :apropos, :help, :keymap, :options, :ls, :lsp-log, …) so anchoring next to the cursor would produce a visually arbitrary placement. Centring puts them where the eye lands by default.

Variants

CursorAnchored

Anchor adjacent to the document cursor (above / below depending on screen room).

Centered

Centre over the buffer area.

MinibufferBand

Full width of the active pane, anchored to its bottom edge. Which-key’s placement.

Bottom-anchored full-width is what emacs which-key and which-key.nvim both do, and per the UX-convention rule that muscle memory is the default worth keeping. It is also the only placement where the column count is predictable, which is what lets the grid be laid out ahead of the renderer.

Height is content + border, hard-capped at half the pane so the hint can never swallow the buffer it is describing.

Slice: WK.5.
