"FlubuCore - Fluent Builder Core" is a cross platform build and deployment automation system. You can define your build and deployment scripts in C# using an intuitive fluent interface. This gives you code completion, IntelliSense, debugging, FlubuCore custom analyzers, and native access to the whole .NET ecosystem inside of your scripts.

FlubuCore in action

FlubuCore offers a .net (core) console application that uses power of roslyn to compile and execute scripts. Above example can be run from console with:

  • FlubuCore runner flubu.exe Default
  • FlubuCore dotnet cli tool dotnet flubu Default
  • FlubuCore global tool flubu Default

Features and Advantages

  • Intuitive an easy to learn. C#, fluent interface, and IntelliSense make even most complex script creation a breeze.
