• API Documentation
• Samples (TODO)

⚠️ UNDER ACTIVE DEVELOPMENT

Quick Start

Usage

TODO

Development

Build

With dotnet installed with all needed frameworks and Rust installed (i.e. cargo on the PATH), run:

dotnet build

Or for release:

dotnet build --configuration Release

Code formatting

This project uses StyleCop analyzers with some overrides in .editorconfig. To format, run:

dotnet format

Can also run with --verify-no-changes to ensure it is formatted.

VisualStudio Code

When developing in vscode, the following JSON settings will enable StyleCop analyzers in:

    "omnisharp.enableEditorConfigSupport": true,
    "omnisharp.enableRoslynAnalyzers": true

Testing

Run:

dotnet test

Can add options like:

• --logger "console;verbosity=detailed" to show logs
  • TODO(cretz): This doesn't show Rust stdout. How do I do that?
• --filter "FullyQualifiedName=Temporalio.Tests.Client.TemporalClientTests.ConnectAsync_Connection_Succeeds" to run a specific test
• --blame-crash to do a host process dump on crash

To help debug native pieces, this is also available as an in-proc test program. Run:

dotnet run --project tests/Temporalio.Tests

Extra args can be added after --, e.g. -- --verbose would show verbose logs and -- --help would show other options. If the arguments are anything but --help, the current assembly is prepended to the args before sending to the xUnit runner.

Rebuilding Rust extension and interop layer

To regen core interop from header, install ClangSharpPInvokeGenerator like:

dotnet tool install --global ClangSharpPInvokeGenerator

Then, run:

ClangSharpPInvokeGenerator @src/Temporalio/Bridge/GenerateInterop.rsp

The Rust DLL is built automatically when the project is built. protoc may need to be on the PATH to build the Rust DLL.

Regenerating protos

Must have protoc on the PATH. Note, for now you must use protoc 3.x until our GH action downloader is fixed or we change how we download protoc and check protos (since protobuf changed some C# source).

Then:

dotnet run --project src/Temporalio.Api.Generator

Regenerating API docs

Install docfx, then run:

docfx src/Temporalio.ApiDoc/docfx.json

TODO:

• Fix generated api doc
  • Specifically make Temporalio.Api have children collapsed by default
  • Switch/update template to full width
• Formatting/style guide:
  • Line len 100 max on everything where reasonable
  • Rules for options classes
    • Shallow-copyable via virtual clone
    • Empty constructor and constructor with required params
    • TODO(cretz): Validation? Probably don't want attributes?
• Source generator for workflows
