# Go Application Versioning

This repository contains a simple Go application that demonstrates how to embedded version strings that come from Git tags during the build process.

The `version.go` source contains a variable named `Version` that is initialized in the code to `undefined` string constant.
The build command replaces this values with Git tag value optionally suffixed with information about changes since the tag.

The build command uses the `-ldflags` option of the `go build` command to set the value of the `Version` variable at compile time.

```go
go build -o testver -ldflags "-X main.Version=$(VERSION)"
```

The version is captured using the following command:

```shell
VERSION=$(git describe --tags --always)
```

Use `make` command to build the application.
