Is there F# Interactive for Linux on .NET Core, without using Mono?
dotnet core 3 preview 3 supports F# interactive as a pure .NET Core application:
dotnet fsi --readline
Yes there is, but it's hidden in a deep directory.
I have the following script in my $PATH, with name fsi
, to find it and launch it:
#!/bin/sh
dotnet=/usr/bin/dotnet
fsi=/usr/share/dotnet/sdk/*/FSharp/fsi.exe
if ! [ -f $fsi ] 2>/dev/null; then
echo ERROR Cannot find fsi.exe or more than one is present
exit 2
fi
exec $dotnet $fsi "$@"
Result:
$ fsi
Microsoft (R) F# Interactive version 10.2.3 for F# 4.5

With this, you can uninstall Mono and the old fsharp
package.
