Experiments on Go

Go is an open source programming language. To install it, you can either download it from golang.org or use brew:

brew install golang
...
go version
>> go version go1.11.2 darwin/amd64

Run you script hello.go with:

go run pkg/examples/hello.go
>> Hello, World!

Install it in your $GOPATH/bin with:

go install hello.go

You need to set your own $GOPATH for it to work. Check setup.sh to see which path to export, Add the change to your .bashrc to make it permanent.

Run the following command to create a new module:

go mod init <module-name>

This will create a go.mod file in the current directory.

To add a dependency, run:

go get <package-name>

This will add the package to the go.mod file. To install all dependencies, and clean up the go.mod file, run:

go mod tidy

You can also use go mod download which will download all dependencies in the cache.

Run unit tests:

go test ./...

This should run all the tests in the current directory and subdirectories.
