Fedora 27 : Go and atom editor.

The Go programming language was created at Google in 2009 by Robert Griesemer, Rob Pike, and Ken Thompson.
The Go often referred to as golang is a programming language created at Google.
Using go with Fedora 27 is very simple , just install it with dnf tool.
#sudo dnf install golang
To use it with atom editor you need to install the atom editor , see this tutorial.
The next step is to set the atom editor with the packages for go programming language, like:
  • go-plus
  • go-get
  • go-imports
  • platformio-ide-terminal
The go command come with this help:
Go is a tool for managing Go source code.


go command [arguments]
The commands are:

build       compile packages and dependencies
clean       remove object files
doc         show documentation for package or symbol
env         print Go environment information
bug         start a bug report
fix         run go tool fix on packages
fmt         run gofmt on package sources
generate    generate Go files by processing source
get         download and install packages and dependencies
install     compile and install packages and dependencies
list        list packages
run         compile and run Go program
test        test packages

packages    description of package lists

testfunc    description of testing functions
The next step is to install your packages with go command and get:
go get -u golang.org/x/tools/
go get -u github.com/golang/lint/golint
Let's make a simple example:
package main
import "fmt"
func main() {
    fmt.Println("Hello world !")
Let's test it with go command. To run the program, create a file named hello-world.go put the code in and use go run:
$ go run hello-world.go
hello world
If you want to build our programs into binaries, we can do this using go build :
$ go build hello-world.go
$ ls
hello-world hello-world.go
Finally, we can then execute the built binary directly.
$ ./hello-world
hello world
After I searched the internet I found a website with many examples and I recommend it. You can find him here.
