06:48 kyagrd is anyone here now?
06:50 kyagrd I've got a very basic question again. I'm learning to use Isabelle 2015. I just proved some lemma simply attaching "by blast" at the end.
06:50 kyagrd Strange thing is that jedit highlighted the "by blast" with a purple-ish background color, wondering what that means ...
09:22 ThreeOfEight kyagrd: purple background means that the command has not finished yet
09:22 ThreeOfEight it's not really "proven" until the purple background goes away
09:23 ThreeOfEight (it was a bit differently in batch mode, which is why batch mode is typically considered the definitive answer to "Does this proof work or not?")
09:31 kyagrd Oh, then it was not proved
10:42 ThreeOfEight what happens is that "by" forks proofs to the background, which is good for parallelisation
