Display the signature of the current Go function under the cursor in the status bar of Atom
License: MIT License
Warmest greetings.
Is it possible to display current variable type as it occurs for functions?
Thanks.

Hi, I'm 'kinda' new to Atom and I've just installed go-plus which I believe installed go-signature-statusbar too. But I noticed that Atom became very slow while moving the cursor around, so I tried disabling packages one by one... then I found out that when I disable go-signature-statusbar, editing and cursor moving becomes responsive again.
Is there a reason that this package makes my Atom so slow while editing? Perhaps I'm doing something wrong? I'm using 1.17.2 on Windows 10.
Thanks
For example err := json.NewDecoder(r.Body).Decode(&request)
Given this line, the statusbar usually only shows the NewDecoder signature, not the Decode, even when the cursor is within Decode.
The issue has to do with matches.reverse() causing issues with the later loop in lib/go-signature-statusbar-view.js the trivial solution is to funcs.reverse() prior to that loop.
I often have the following problem:
Variable names are not short enough and too many arguments are present in function signature.
Thus, I can only see some portion of it. It may be nice if I can adjust the width. I noticed your commit 17ff9e0 and changed package.json to increase the width. After restarting Atom width increased but nevertheless some functions just don't fit there.
In fact, it would be great if a popup is shown since functions may have many arguments and status bar i not long enough to show it. However this repo's name is go-signature-statusbar so maybe it's not fit for this project :)
Is it possible to add type info for variables?

It seems that the method signature is truncated after it reaches a certain length. I had a quick look at the code and couldn't see this happening intentionally so it may be coming from autocomplete.

When I check which version of go-plus that is installed in the packages list the version is "undefined".
Could it be some local config causing it?
Happens only if the function is not returning anything.
First, I really like the plugin.
Have you looked at Guru instead if GoCode? With Guru I think your code would become a bit easier and you could also get more information. Please note that I have truncated file paths bellow to make examples easier to read in the issue.
Package: golang.org/x/tools/cmd/guru
Example on function:
guru describe main.go:#323
main.go:21.25-21.39: reference to method func (*github.com/gorilla/mux.Route).GetPathTemplate() (string, error)
github.com/gorilla/mux/route.go:549:17: defined here
Example on variable (definition):
main.go:21.2-21.9: definition of var template string
Example on variable (same as above but when used)
main.go:25.31-25.38: reference to var template string
main.go:21:2: defined here
Example of constant:
main.go:27.42-27.44: reference to const url untyped string of constant value "http://example.com"
main.go:12:7: defined here
With this type of information there are two benefits:
1 . Support is extended to show type information on variables and constants, and not just function signature
2. Links can be created for "jump to definition"
If possible please add an option for setting default font size, this will be very useful.
