# Profile Builder
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
|
||
|
|
Azure Profiles offer a means of virtualizing the API Versions of services that should be targeted by an application or SDK.
|
||
|
|
This concept was introduced for [Azure Stack](https://azure.microsoft.com/overview/azure-stack), where the environment in
|
||
|
|
which applications will be executed is less consistent than when targeting the public cloud. However, its usefulness as a
|
||
|
|
means of easily snapping to versions of a service is broadly applicapable. Using profiles, it is easy to use a single version
|
||
|
|
of models and operations throughout an application, or a means of locking to versions of services that have been tested and
|
||
|
|
are guaranteed to work together.
|
||
|
|
|
||
|
|
[Type aliases were introduced in Go 1.9](https://golang.org/doc/go1.9#language), effectively allowing for multiple symbols
|
||
|
|
to be mapped to a single type. The impact of this for our support of profiles is tremendous. It allows for seamless
|
||
|
|
interoperability between packages using different profiles, but where those profiles still target the same API Version of a
|
||
|
|
service. Without type aliases, we would have been forced to generate code in a way that required some ugly casts to be
|
||
|
|
scattered throughout the consumer's code.

## Installation
|
||
|
|
|
||
|
|
*Note:* These installation notes assume that you have [Go 1.9](https://blog.golang.org/go1.9) or higher, [Glide](http://github.com/Masterminds/glide), and [Git](https://git-scm.com/) installed.
|
||
|
|
|
||
|
|
The simplest version of installation is simple, just run the following command:
|
||
|
|
|
||
|
|
``` bash
|
||
|
|
go get -u github.com/Azure/azure-sdk-for-go/tools/profileBuilder
|
||
|
|
```
|
||
|
|
|
||
|
|
If that causes you trouble, run the following commands:
|
||
|
|
|
||
|
|
``` bash
|
||
|
|
# bash
|
||
|
|
go get -d github.com/Azure/azure-sdk-for-go/tools/profileBuilder
|
||
|
|
cd $GOPATH/src/github.com/Azure/azure-sdk-for-go/tools/profileBuilder
|
||
|
|
glide install
|
||
|
|
go install
|
||
|
|
```
|
||
|
|
|
||
|
|
``` PowerShell
|
||
|
|
# PowerShell
|
||
|
|
go get -d github.com/Azure/azure-sdk-for-go/tools/profileBuilder
|
||
|
|
cd $env:GOPATH\src\github.com\Azure\azure-sdk-for-go\tools\profileBuilder
|
||
|
|
glide install
|
||
|
|
go install
|
||
|
|
```
|
||
|
|
Taking things a step further, if you'd like the profileBuilder to stamp the version of itself in the code it generates, you can install as below:
|
||
|
|
|
||
|
|
``` bash
|
||
|
|
# bash
|
||
|
|
go get -d github.com/Azure/azure-sdk-for-go/tools/profileBuilder
|
||
|
|
cd $GOPATH/src/github.com/Azure/azure-sdk-for-go/tools/profileBuilder
|
||
|
|
glide install
|
||
|
|
export currentCommit=$(git rev-parse HEAD)
|
||
|
|
go install -ldflags "-X main.version=$currentCommit"
|
||
|
|
```
|
||
|
|
|
||
|
|
``` PowerShell
|
||
|
|
# PowerShell
|
||
|
|
go get -d github.com/Azure/azure-sdk-for-go/tools/profileBuilder
|
||
|
|
cd $env:GOPATH\src\github.com\Azure\azure-sdk-for-go\tools\profileBuilder
|
||
|
|
glide install
|
||
|
|
$currentCommit = git rev-parse HEAD
|
||
|
|
go install -ldflags "-X main.version=$currentCommit"
|
||
|
|
```
