Introduction

Runesmith is a code editor for Windows, Linux and macOS, built on .NET 10 and Avalonia. It opens a folder, shows its files, and edits them with highlighting for more than 60 languages. For C#, Runesmith's own analyzer adds completion, signature help, hover, go to definition and problems as you type, and Build runs dotnet build and lists what the compiler found.

What this version does​

This is the first version, the MVP. It focuses on editing C#:

  • A docking workspace in light and dark. Panels and editors drag to any edge, into another group or out into a window of their own.
  • An editor with syntax highlighting, typing aids such as closing brackets and keeping indentation, and find and replace.
  • Completion, signature help, hover, go to definition and problems. For C# they come from Runesmith's own analyzer, built on the C# compiler, with nothing to install; plugins can add language servers for other languages.
  • Quick open, the command palette, find in files, the Problems and Output panels and building.
  • Settings for you and for each folder, key bindings you can change, and plugins that add languages, commands, panels and more.
