Pekspro.BuildInformationGenerator 0.0.1-preview03

Pekspro.BuildInformationGenerator

A source generator package that generates build information constants, like build time, commit id, branch etc.

Installation

Add the package to your application with:

dotnet add package Pekspro.BuildInformationGenerator

This adds a <PackageReference> to your project. You can additionally mark the package as PrivateAssets="all" and ExcludeAssets="runtime".

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
  </PropertyGroup>

  
  <PackageReference Include="Pekspro.BuildInformationGenerator" Version="0.0.1" 
    PrivateAssets="all" ExcludeAssets="runtime" />
  

</Project>

Setting PrivateAssets="all" means any projects referencing this one won't get a reference to the Pekspro.BuildInformationGenerator package.

Setting ExcludeAssets="runtime" ensures the Pekspro.BuildInformationGenerator.Attributes.dll file is not copied to your build output (it is not required at runtime).

Usage

Create a new partial class in your project and add the [BuildInformation] (from the Pekspro.BuildInformationGenerator namespace) attribute to it. For example:

[BuildInformation]
partial class MyBuildInformation
{

}

This will generate a class called MyBuildInformation (by default), which contains a number of constants. For example:

static partial class MyBuildInformation
{
    /// <summary>
    /// Build time: 2024-06-09 13:12:59
    /// </summary>
    public static readonly global::System.DateTime BuildTime = new global::System.DateTime(638535355790224470L, global::System.DateTimeKind.Utc);

    /// <summary>
    /// The commit id in Git at the time of build: 712f143d13df1dcffad122a4184cb19b0c5424f3
    /// </summary>
    public const string GitCommitId = "712f143d13df1dcffad122a4184cb19b0c5424f3";

    /// <summary>
    /// The short commit id in Git at the time of build: 712f143
    /// </summary>
    public const string GitShortCommitId = "712f143";
}

You can also specify which properties to include in the generated class. For example:

[BuildInformation(IncludeGitBranch = true)]
partial class MyBuildInformation
{

}

This will add the GitBranch property to the generated class:

/// <summary>
/// Git branch: master
/// </summary>
public const string GitBranch = "master";

Configuration

The [BuildInformation] attribute has a number of properties you can set to control the generated class.

If everything is set to true, the generated class will look like this:

static partial class BuildInfoAll
{
    /// <summary>
    /// Build time: 2024-06-09 14:05:48
    /// </summary>
    public static readonly global::System.DateTime BuildTime = new global::System.DateTime(638535387484914951L, global::System.DateTimeKind.Utc);

    /// <summary>
    /// Build time: 2024-06-09 16:05:48 (+02:00))
    /// </summary>
    public static readonly global::System.DateTimeOffset LocalBuildTime = new global::System.DateTimeOffset(638535459484914951L, new global::System.TimeSpan(72000000000));

    /// <summary>
    /// OS version of the building machine: Microsoft Windows NT 10.0.22631.0
    /// </summary>
    public const string OSVersion = "Microsoft Windows NT 10.0.22631.0";

    /// <summary>
    /// The commit id in Git at the time of build: 712f143d13df1dcffad122a4184cb19b0c5424f3
    /// </summary>
    public const string GitCommitId = "712f143d13df1dcffad122a4184cb19b0c5424f3";

    /// <summary>
    /// The short commit id in Git at the time of build: 712f143
    /// </summary>
    public const string GitShortCommitId = "712f143";

    /// <summary>
    /// Git branch: master
    /// </summary>
    public const string GitBranch = "master";

    /// <summary>
    /// .NET SDK version: 8.0.300
    /// </summary>
    public const string DotNetSdkVersion = "8.0.300";

    /// <summary>
    /// Workload MAUI version: 8.0.21/8.0.100
    /// </summary>
    public const string WorkloadMauiVersion = "8.0.21/8.0.100";

    /// <summary>
    /// Workload wasm-tools version: 8.0.5/8.0.100
    /// </summary>
    public const string WorkloadWasmToolsVersion = "8.0.5/8.0.100";
}

Performance

You can also specify if you want to have faked values (to increase build time) with these settings:

Requirements

This source generator requires the .NET 7 SDK. You can target earlier frameworks like .NET Core 3.1 etc, but the SDK must be at least 7.0.100.
