TheAngryByrd.TypeSafeInternals

What

This uses Myriad to generate type safe reflection calls to internal functions/properties/methods.

Why

Sometimes you have to use reflection and there's no simple way around it. When creating reflection calls to internal/private functions/properties/methods, the underlying function may change when you go to upgrade the dependency. With TypeSafeInternals, it will re-generate the code for the calls so you would get a compile error if the API has drifted.

How

1. Install TheAngryByrd.Myriad.Plugins.TypeSafeInternals via Nuget or Paket.

2. Create an empty myriad.toml file next to your fsproj file.

3. Add this xml snippet to your fsproj file.

   <Compile Include="Generated.fs">
       <MyriadFile>TypeSafeInternals.txt</MyriadFile>
   </Compile>

4. Create TypeSafeInternals.txt next to you fsproj file.

5. Add the name of the Nuget package (such as Npgsql.FSharp) to TypeSafeInternals.txt.

6. run dotnet build

Developing

Make sure the following requirements are installed on your system:

• dotnet SDK 5.0 or higher

or

• VSCode Dev Container

---

Environment Variables

• CONFIGURATION will set the configuration of the dotnet commands. If not set, it will default to Release.
  • CONFIGURATION=Debug ./build.sh will result in -c additions to commands such as in dotnet build -c Debug
• GITHUB_TOKEN will be used to upload release notes and Nuget packages to GitHub.
  • Be sure to set this before releasing
• DISABLE_COVERAGE Will disable running code coverage metrics. AltCover can have severe performance degradation so it's worth disabling when looking to do a quicker feedback loop.
  • DISABLE_COVERAGE=1 ./build.sh

---

Building

> build.cmd <optional buildtarget> // on windows
$ ./build.sh  <optional buildtarget>// on unix

The bin of your library should look similar to:

$ tree src/MyCoolNewLib/bin/
src/MyCoolNewLib/bin/
└── Debug
    └── net50
        ├── MyCoolNewLib.deps.json
        ├── MyCoolNewLib.dll
        ├── MyCoolNewLib.pdb
        └── MyCoolNewLib.xml

Build Targets

• Clean - Cleans artifact and temp directories.
• DotnetRestore - Runs dotnet restore on the solution file.
• DotnetBuild - Runs dotnet build on the solution file.
• DotnetTest - Runs dotnet test on the solution file.
• GenerateCoverageReport - Code coverage is run during DotnetTest and this generates a report via ReportGenerator.
• WatchTests - Runs dotnet watch with the test projects. Useful for rapid feedback loops.
• GenerateAssemblyInfo - Generates AssemblyInfo for libraries.
• DotnetPack - Runs dotnet pack. This includes running Source Link.
• SourceLinkTest - Runs a Source Link test tool to verify Source Links were properly generated.
• PublishToNuGet - Publishes the NuGet packages generated in DotnetPack to NuGet via paket push.
• GitRelease - Creates a commit message with the Release Notes and a git tag via the version in the Release Notes.
• GitHubRelease - Publishes a GitHub Release with the Release Notes and any NuGet packages.
• FormatCode - Runs Fantomas on the solution file.
• BuildDocs - Generates Documentation from docsSrc and the XML Documentation Comments from your libraries in src.
• WatchDocs - Generates documentation and starts a webserver locally. It will rebuild and hot reload if it detects any changes made to docsSrc files, libraries in src, or the docsTool itself.
• ReleaseDocs - Will stage, commit, and push docs generated in the BuildDocs target.
• Release - Task that runs all release type tasks such as PublishToNuGet, GitRelease, ReleaseDocs, and GitHubRelease. Make sure to read Releasing to setup your environment correctly for releases.

Releasing

• Start a git repo with a remote

git add .
git commit -m "Scaffold"
git remote add origin https://github.com/user/MyCoolNewLib.git
git push -u origin master

• Create your NuGeT API key

  • Add your NuGet API key to paket

    paket config add-token "https://www.nuget.org" 4003d786-cc37-4004-bfdf-c4f3e8ef9b3a

  • or set the environment variable NUGET_TOKEN to your key

• Create a GitHub OAuth Token

  • You can then set the environment variable GITHUB_TOKEN to upload release notes and artifacts to github
  • Otherwise it will fallback to username/password

• Then update the CHANGELOG.md with an "Unreleased" section containing release notes for this version, in KeepAChangelog format.

NOTE: Its highly recommend to add a link to the Pull Request next to the release note that it affects. The reason for this is when the RELEASE target is run, it will add these new notes into the body of git commit. GitHub will notice the links and will update the Pull Request with what commit referenced it saying "added a commit that referenced this pull request". Since the build script automates the commit message, it will say "Bump Version to x.y.z". The benefit of this is when users goto a Pull Request, it will be clear when and which version those code changes released. Also when reading the CHANGELOG, if someone is curious about how or why those changes were made, they can easily discover the work and discussions.

Here's an example of adding an "Unreleased" section to a CHANGELOG.md with a 0.1.0 section already released.

## [Unreleased]

### Added
- Does cool stuff!

### Fixed
- Fixes that silly oversight

## [0.1.0] - 2017-03-17
First release

### Added
- This release already has lots of features

[Unreleased]: https://github.com/user/MyCoolNewLib.git/compare/v0.1.0...HEAD
[0.1.0]: https://github.com/user/MyCoolNewLib.git/releases/tag/v0.1.0

• You can then use the Release target, specifying the version number either in the RELEASE_VERSION environment variable, or else as a parameter after the target name. This will:
  • update CHANGELOG.md, moving changes from the Unreleased section into a new 0.2.0 section
    • if there were any prerelease versions of 0.2.0 in the changelog, it will also collect their changes into the final 0.2.0 entry
  • make a commit bumping the version: Bump version to 0.2.0 and adds the new changelog section to the commit's body
  • publish the package to NuGet
  • push a git tag
  • create a GitHub release for that git tag

macOS/Linux Parameter:

./build.sh Release 0.2.0

macOS/Linux Environment Variable:

RELEASE_VERSION=0.2.0 ./build.sh Release
