为什么本地软件包的自动完成功能不能在Atom编辑器中工作？

Question

Autocomplete (go-plus) works fine in Atom for standard library imports, but whenever I try to import my own packages It simply doesn't work.

My package structure goes like this:

.
├── bin
├── pkg
└── src
    └── Test
        ├── MyPackage
        │   └── hello.go
        └── main.go

main.go

package main

import (
    "Test/MyPackage"
)

func main() {
    hello.SayHello("World")
}

hello.go

package hello

import "fmt"

const Msg = "Hello "

func SayHello(name string) {
    fmt.Printf("%v%v!
", Msg, name)
}

The file compiles fine, but in main.go the hello package does not invoke any autocompletion in Atom, so what could be the problem?

The issue is addressed in the README.md of the go-plus package:

First of all, make sure autocomplete-plus is present on your setup. Go-plus provides autocompletion through gocode tool, so you should ensure it's in PATH and available.

If you can't get autocompletion for the user-defined packages working, while it's there for packages from standard library, it's likely a trivial gocode-related issue. Try running gocode set. Some expected output'd be: propose-builtins false lib-path "" autobuild false force-debug-output "" package-lookup-mode "go"

What you gotta do is switching autobuild to true, by running gocode set autobuild true. Check autocompletion now, it must be working right.
