# 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. |
