@felixcheung @jongyoul I have updated the PR to run the paragraph text once
instead of breaking it into lines. But it leads one behavior change: the order
of output is changed compared to previous implementation. Basically there're
two kinds of outputs: repl output and code execution output. e.g.g
```
val a = "hello world"
println(a)
```
Output
```
hello world (This is code execution output)
a: String = hello world (This is repl output)
```
Code execution output will be displayed while code is running, but repl
output is only displayed after scala repl complete the code execution. That's
why you will see that the repl output is always after the code execution
output, that's why I update some test code in this PR.
