- [Internal directory](https://github.com/gophertuts/go-basics/blob/master/internal-directory)

### Installation

Before trying any of these examples make sure to have the `Go` binary installed on your platform.

OSX:

```bash
# Install Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
```

```bash
# Install Go

brew install go
```

Linux:

```bash
# Move into $HOME directory
cd ~

# Download the binary for your distribution
curl -O https://dl.google.com/go/go1.12.linux-amd64.tar.gz

# Verify that the downloaded binary is not corrupted. Check if the hash matches the one from downloads page
sha256sum go1.12.linux-amd64.tar.gz

# Extract the binary
tar xvf go1.12.linux-amd64.tar.gz

# Make root user the owner of Go workspace
sudo chown -R root:root ./go

# Move go directory to a standard location
sudo mv go /usr/local
```

For more details regarding `Go` installation check out

[Golang Installation](https://golang.org/doc/install)

For downloading `Go` binary for your platform checkout

[Golang Downloads](https://golang.org/dl/)

To check if you installed `Go` successfully type:

```bash
# Displays installed Go version
go version

# Displays all environment variables defined by Go
go env
```

Docker:

```bash
docker run -it golang:1.11
```

### Set $GOPATH variable
```bash
sudo nano ~/.profile

# Linux
export GOPATH=/usr/local/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:/$GOBIN

# OSX
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:/$GOBIN

# Save File

# Restart shell configuration
source ~/.profile
```

### Other Go tools

You can also install other `Go` tools which will help you have a more productive development process

- [Go Tools](https://github.com/golang/tools)
- [Go Lint](https://github.com/golang/lint)
- [Go Imports](https://godoc.org/golang.org/x/tools/cmd/goimports)

#### Go Tools

```bash
go get -u golang.org/x/tools/...
```

#### Go Lint

```bash
go get -u golang.org/x/lint/golint
```

#### Go Imports

```bash
go get -u golang.org/x/tools/cmd/goimports
```

#### Daily routine things

- Format your entire code recursively using
`go fmt ./...`

- Lint your entire code recursively using
`golint ./...`
