Disable lsp-ui-doc on cursor by default

[ericdallo]

I'm opening this as IMO we should not show the lsp-ui-doc glance popup when cursor stops on a symbol, IMO we should only show if hovering with the mouse, this causes a lot of notice on lsp-ui package.

WDYT?

Can you elaborate on exactly how this would work? As I mentioned in gitter yesterday I love being able to get docs, but as a focus-follows-mouse user it badly breaks my workflow because as I move point around if a doc popup appears under my mouse cursor it "breaks" continuous key presses. For example, I use C-s then type something then start hitting C-s repeatedly; when the popup breaks this it stops repeating. Continuously hitting C-s doesn't help because it constantly breaks. I have to remember to keep my mouse cursor down near the bottom of the window to reduce the chances that the popup appears under it, which I consistently fail to do.

Even more galling is when I'm in the middle of an undo cycle: once the undo cycle is broken then it starts to redo! I am so used to the traditional undo in Emacs, and normally like it, that I can't switch to one of the new different undo methods.

Anyway. I would like it if I explicitly move the mouse to hover over something and then a doc popup appeared. But how is that distinguished from, say, page down and your mouse now happens to hover over some symbol? Would a doc popup appear here as well?

I've been meaning to investigate how lsp-ui-doc-show-with-mouse and lsp-ui-doc-show-with-cursor work but haven't found time: how is this request different from those?

Well you can already disable the popup: just set lsp-ui-doc-enable to nil :). The question is really, what operation should show the popup and how exactly will it work (from a user perspective)?

Thanks for raising this.

I have my lsp-ui-doc-enable disabled already, the problem I see here is that when lsp-ui-doc-enable is t, it shows only with cursor hover without any user action like calling a command or hovering with mouse instead of cursor, which makes most users want to disable that annoying popup.
When I want to see the docs I can manually trigger lsp-ui-doc-glance or lsp-ui-doc-show.

Ok if you use a mouse -- believe it or not there are some of us that don't -- also I've noticed that lsp-haskell is not reliable in showing the brief type info the modeline (which is odd as the doc seems to work better) thus so I've had to re-enable it.

@sebeaumont

Most likely setting lsp-eldoc-render-all to t will fix this issue.

@yyoncho Thanks for the tip.

[Martinsos]

If I am correct, lsp-ui-doc on cursor is now disabled on default, is it? In that case, is there a way to re-enable this behaviour via some setting?

[ericdallo]

yes, (setq lsp-ui-doc-show-with-cursor t)
