Is it possible to use childframe for eglot?

[FirstLoveLife]

Just come from lsp-mode then found this great package, thanks for you great work!

I noticed unlike lsp-uii's childframe, eglot usually uses side-window(just like helm instead of minibuffer from ivy). I wonder is it possible to use childframe in eglot? Because I have to move my eyes frequently when using side-window.

I don't know what you mean by lsp-uii's childframe. What is side-window that eglot uses? I think you are talking about an Emacs feature, but it would be great if you post a screenshot so we can understand what you are talking about.

[FirstLoveLife]

Sure.

lsp-ui:

eglot:

As the pictures show, lsp-ui can use child-frame, so it has window which is close to my code. Eglot's doc window is always at bottom, just like helm's default layout. IMO, eglot will be nicer if it can use child-frame.

BTW, I know it is just personal taste for the choice of childframe or side-window and childframe will never be a must. But if eglot can provide the option of childframe, I will pretty appreciate.

Hi @FirstLoveLife ,

I wonder is it eglot-help-at-point to get this help doc? It's handy.

I try this command in a c++ project, eglot prompts me a *eglot help* buffer,
so I'm not sure if it is the command.

@whatacold Good to know this function. But i think it is not as flexible as child-frame from lsp-ui

@FirstLoveLife ,

Maybe I haven't make me clear :(

Actually I want to know how do you show up the side window as shown in the picture, in the elgot manner?
It doesn't look like a *eglot-help* buffer as I mentioned.

[FirstLoveLife]

It doesn't look like a eglot-help buffer as I mentioned.

Yes. With eglot-help-at-point, the eglot-help buffer is positioned side by side(just like what C-x 3 does.

Actually I want to know how do you show up the side window as shown in the picture, in the elgot manner?

I didn't do anything. eglot's default config use side-window above when any lsp is hooked by eglot, including ccls

I see now, it's a textDocument/hover response shown by eldoc-message function.
I haven't noticed it as I truncated the message, and now I can see the whole multi-line message
after setting (setq message-truncate-lines nil) , which is the default.

Thanks.

There seems to be a workaround, and also this kind of UI functionality isn't anything that Eglot should be supporting anyway (emacs's own display-buffer-alist or modes like company-quickhelp-mode seem more appropriate).

I cooked up some code to use childframe: https://github.com/casouri/eglot-doc

[joaotavora]

@casouri, could you maybe do this in eldoc-message-function exclusively (and thus provide this service to non-Eglot users) like I suggest in #111? It would also probably need less Eglot-specific code and custom requests.

[casouri]

Done. I removed eglot dependency and renamed it to eldoc-box.

Oh very nice, going to try it out with my minor modes
