I need to make a custom REPL, and spoiled by bpython/ipython I wonder if exist something similar to it?
I wish to provide colored output, history, code completion, as close to http://ballingt.com/2014/05/13/bpython-curtsies-release.html as possible.
Check out FSharp.Compiler.Services.
I don't know bpython, but this sounds reasonably close.
