claire

System: Microsoft Windows 10 Home Edition
CPUs: Intel(R) Core(TM) i5-3230M CPU @2.60GHz
GPU: Mesa DRI Intel(R) HD Graphics 4000
Deps: go1.24.3.windows-amd64.zip

Y. Caseau's claire uses Go as its target language.

https://go.dev/doc/install

This is beta as of January 3, 2025.

Use a system installed Go.

In PowerShell from $home run these commands after cloning the repository.

    •  New-Item -ItemType Directory -Name "go"
    •  Move-Item CLAIRE4\init.cl go
    •  Move-Item CLAIRE4\src go
    •  Set-Location go
    •  $env:GO111MODULE = "off"
    •  go build src\claire4.go

You should then have a claire4.exe file in the current directory.
