# GOLANG configurations in .config/fish/config.fish
set -x GOPATH $HOME/<Go_directory>
set -x GOROOT /usr/local/opt/go/libexec
set PATH $GOPATH/bin $GOROOT/bin $PATH

# test your setup 
# inside the hello directory create a file named hello.go with the following contents:

package main

import "fmt"

func main() {
    fmt.Printf("hello, world\n")
}

# Then compile it with the go tool:
go install github.com/<user>/hello

# The above command will put an executable command named hello (or hello.exe) inside the bin directory of your workspace.
# Execute the command to see the greeting:
$GOPATH/bin/hello
