sbt clear screen command

Question

I am learning sbt build tool. I use interpreted sbt. I run lot of commands and get lot of output which clutters up the screen.

The question

Answer 1

Sbt will load ~/.sbt/1.0/build.sbt as global settings.

commands += Command.command("cls") { state =>
  print("\033c")
  state
}

Then you can run any commands with cls. For example:

• ~;cls;compile
• ~;cls;testOnly

Answer 2

In bash you should be able to use Ctrl+L, on OSX you can also use Cmd+K.

Answer 3

This specifically helps when you're doing something in continuous mode, ala `compile:

maxErrors := 5
triggeredMessage := Watched.clearWhenTriggered

This works as of 0.13.7. The second line clears the screen before each command runs. The first line limits the number of errors. With this config, you only ever have one screen full of errors to work through. Obviously could adjust maxErrors depending on your sbt window.
