Simplify Source Generator creation the RoslynGenerator template

I’m currently writing my own Source generator which can become quite challenge. Yesterday I talked about RoslynQuoter as one of the tools that helped me along the way. Today I want to show you an easy way to get started thanks to the F0.Templates project.

Start by installing the F0.templates using dotnet new --install F0.Templates:

Now create a new project using the installed RoslynGenerator template dotnet new roslyngenerator.

This will create not only a SourceGenerator project but also a unit and integration tests project and a benchmark project:

Inside the projects we find a simple example of an incremental source generator that searches for methods with the [HelloWorld] attribute and generates an implementation:

Remark: If you are looking for a list of existing generators, take a look here: amis92/csharp-source-generators: A list of C# Source Generators (not necessarily awesome) and associated resources: articles, talks, demos. (github.com)

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cleaner switch expressions with pattern matching in C#

Ever find yourself mapping multiple string values to the same result? Being a C# developer for a long time, I sometimes forget that the C# has evolved so I still dare to chain case labels or reach for a dictionary. Of course with pattern matching this is no longer necessary. With pattern matching, you can express things inline, declaratively, and with zero repetition. A small example I was working on a small script that should invoke different actions depending on the environment. As our developers were using different variations for the same environment e.g.  "tst" alongside "test" , "prd" alongside "prod" .  We asked to streamline this a long time ago, but as these things happen, we still see variations in the wild. This brought me to the following code that is a perfect example for pattern matching: The or keyword here is a logical pattern combinator , not a boolean operator. It matches if either of the specified pattern...
