Type hinting on cursor hover

[pkieltyka]

Is there a way for go-plus, or something in combination with it to output the type of a variable or function definition where the cursor is placed? This is something GoSublime does in Sublime and its very useful. The auto-complete stuff is cool, albeit, a bit overzealous (ie. its code-completing in a comment...), but knowing the types of code once its already written would be very nice :)

I agree, this is worth doing.

You can suppress completion in a comment via the Autocomplete Scope Blacklist preference, which is set by default to a scope of .source.go .comment. If you're getting suggestions in comments, they're not coming from gocode, they are from other packages you have installed. You can suppress scopes for all providers using the autocomplete-plus preference: Scope Blacklist.

Type hinting is probably the one thing I miss the most. This is also very close to godoc support. Depending on how the UI is constructed.

What I'd actually love is something similar to GoInfo from vim-go where it shows the type info for the item under the cursor in the statusline:

That is very nice. In atom that could be combined with links to definition and documentation.

Here's some code we use for @OmniSharp https://github.com/OmniSharp/omnisharp-atom/blob/1babb843c03982f18ab8819274d14e1225c54194/lib/omnisharp-atom/views/tooltip-view.ts

That will give the tooltips in Atom, we just need the API to call out when the mouse is hovering over a type

Yes, this would be really awesome

+1 This is what I would really need for productive go coding in Atom.
I use the hinting feature all the time in Sublime Text 3 + GoSublime Plugin to see the parameters and return values of functions.

+1 you can see this working nicely as well in the https://github.com/Microsoft/vscode-go package

Is there any workaround available until this is officially implemented?

This functionality is provided in https://atom.io/packages/go-signature-statusbar. I think it would be nice to include this in go-plus, but I want to come up with an effective solution for #469 (comment) before including it.

[joefitzgerald]

This is now included in v5.0.0 of go-plus.
