Problem:
Spacing around inlay hints has the same highlight as the hint itself.
The LSP spec for inlay hints specifically mentions the padding should not be
coloured:
/**
Render padding before the hint.
Note: Padding should use the editor's background color, not the
background color of the hint itself. That means padding can be used
to visually align/separate an inlay hint.
*/
paddingLeft?: boolean;
/**
Render padding after the hint.
Note: Padding should use the editor's background color, not the
background color of the hint itself. That means padding can be used
to visually align/separate an inlay hint.
*/
paddingRight?: boolean;
Solution:
Add the space as separate parts of the virtual text, don't add the space to the
text itself.
Add automatic refresh and a public interface on top of #23736
* add on_reload, on_detach handlers in `enable()` buf_attach, and
LspDetach autocommand in case of manual detach
* unify `__buffers` and `hint_cache_by_buf`
* use callback bufnr in `on_lines` callback, bufstate: remove __index override
* move user-facing functions into vim.lsp.buf, unify enable/disable/toggle
