"Switch Tab On Check" not working?

[edsko]

After building finishes, it stays on the "Build" tab, rather than switch the "Error" tab, independent of whether this setting is checked or not.

Well, that's kinda expected, although maybe not necessarily wanted. The idea here is as follows: the leftmost tab that has received messages is activated. Problem is, build output usually keeps going even after errors are reported. Maybe grouping messages that came in some reasonable time window (say, about 150 ms?) will resolve this.

I see. So what is your workflow here? Every time I build I then have to manually click on the 'Error' tab to see my compile errors.

I usually see errors before building, actually, either via ghc-mod or ghci, so this doesn't bother me as much. I definitely see your point though, so I'm not saying that this isn't a problem. Just that it behaves exactly as intended by the implementation. I'll look into it in the next couple days.

Meanwhile, patching https://github.com/atom-haskell/ide-haskell/blob/master/lib/output-panel/index.js#L51 to read

this.activateFirstNonEmptyTab(this.tabs.keys());

should work, although with it's own set of challenges (f.ex. if there are warnings, it will lock on to warnings, regardless of anything else going on, etc)

Okay, so I actually managed to find a bug in the implementation and fixing it helped somewhat. But I also added temporal grouping to messages just in case. Published as [email protected]

Indeed, much better! Thanks so much for the quick turnout, as always :)
