mermaid

I wrote about PlantText before. It is about creating diagrams with code. mermaid is another one from the same category. Recently GitHub has given support for this.

I tried to create some class diagrams with mermaid online editor.

    class ILog {
        <<interface>>
        void LogInfo(string message)
        void LogWarn(string message)
        void LogError(string message)
    }

    class ConsoleLog {
        void LogInfo(string message)
        void LogWarn(string message)
        void LogError(string message)
    }
    ILog --|> ConsoleLog : Implements

Azure DevOps release pipeline

Some days ago I wrote a blog post about Azure release Pipelines (CD) and how we can’t use YAML in that. The only option is to do it visually with designer. If I compare this with GitHub workflows, there we can write CI and CD both in YAML syntax.

After that I found a blog post from Microsoft dev blog saying we can use YAML for CD in Azure Pipelines as well. Designing a release pipeline visually with designer, is a legacy way of doing CD now.
