Syntax highlighting in scalac errors

It would be great if SBT applying a few ansi colours to scalac output to make it easier to read. When I get 50 messgaes in a row like this ↓ it’s pretty hard to even see which file the error’s in.

[error] /home/golly/XxxXxx/projects/xxxxx/Code/webapp-client/src/main/scala/xxxxx/webapp/c
lient/app/ui/xxxx/edit/ColumnEditors.scala:136: not enough arguments for method apply: (in

xx.webapp.base.data.Project], textSearch: japgolly.scalajs.react.extra.Px[xxxxx.webapp.bas
e.text.TextSearch], lookupM: japgolly.scalajs.react.extra.Px[xxxxx.base.util.Must[xxxxx.we
bapp.client.app.ui.Xxxtable.edit.ImplicationEditor.Lookup]], update: xxxxx.webapp.client.a

fect.IO[Unit])xxxxx.webapp.client.app.ui.Xxxtable.Cell.State in object ImplicationEditor.
[error] Unspecified value parameter finish.

Btw, is it possible to add this as setting in my own SBT config? I was hoping to intercept all error logging messages and just apply a few regexs it doesn’t seem possible to modify the global logger. All I could find was info on extraLoggers, where as in this case you’d wouldn’t want to add loggers, just replace the global one.

I suspect this is because Defaults.scala:849 (in sbt 0.13.9) scopes compilerReporter under both the Compile configuration and the compile task. You can see this using inspect and notice that for compile:compilerReporter there are no reverse dependencies and hence it’s not used by anything, whereas compile:compile::compilerReporter tells a different story:

> inspect compile:compilerReporter
[info] No entry for key.
...

> inspect compile:compile::compilerReporter
[info] Task: scala.Option[xsbti.Reporter]
[info] Description:
[info]  Experimental hook to listen (or send) compilation failure messages.
[info] Provided by:
[info]  {file:/data/home/dsandul/testProj/}testProj/compile:compile::compilerReporter
[info] Defined at:
[info]  (sbt.Defaults) Defaults.scala:849
[info] Reverse dependencies:
[info]  testProj/compile:compileIncremental
...

So I’d just set

compilerReporter in (Compile, compile) := Some(new MyLoggerReporter(5, streams.value.log))

I think this should be something implemented in Scala itself.
