goimports无法与vim-go插件配合使用

Question

I followed the installation instructions here https://github.com/fatih/vim-go and ran goimports hello.go. The output was my code with the imported package but when I opened hello.go the file did not have the code for the imported package.

Am I missing something?

Answer 1

try

goimports -w=true hello.go

to rewrite source instead of output to stdout

Answer 2

Open the following go source file with your vim.

package main

func main() {
    fmt.Println(strings.ToUpper("hello"))
}

Then run GoImports in vim command line, the file should be updated to:

package main

import (
    "fmt"
    "strings"
)

func main() {
    fmt.Println(strings.ToUpper("gopher"))
}

I am using mvim 8.0.1420 on macOS 10.13.2. And vim-go version is d2b0a234ffb5441a3488c78fe8e5f551ddbdd454.
