Ye I tried that first but it didn't work, nb_available was always zero.
For now I have a hack that works:
while true
statement, newpos = parse(code, __pos, raise=false)
statement.head == :error ? break: (__pos = newpos)
__io, _ = redirect_stdout()
print("x")
eval(statement)
redirect_stdout(STDOUT_OLD)
result = readavailable(__io)
close(__io)
if length(result) > 1
push!(__output, (__pos, result[2:end]))
end
end
