Installation

ilrepl needs the .NET 10 SDK or runtime. The front-end is a Native AOT executable; the part that compiles and runs IL is a small framework-dependent host that ships inside the package and runs on your dotnet.

dotnet tool

dotnet tool install -g ilrepl
ilrepl

On the platforms with a native package (Windows, Linux, macOS on x64 and Arm64) the SDK installs the Native AOT build. Everywhere else the portable build runs on the JIT.

From source

git clone https://github.com/willibrandon/ilrepl
cd ilrepl
dotnet run --project src/IlRepl

dotnet build also publishes the host into host/ beside the front-end, which is how the tool finds it. To point at a different host, set ILREPL_HOST_PATH.

Checking the install

ilrepl -e 'ldc.i4 6; ldc.i4 7; mul; ret'

prints
