Thanks for the contribution. CI says

/home/travis/build/foundweekends/giter8/library/src/main/scala/g8.scala isn't formatted properly!

could you run scalafmt from sbt please?

[pme123]

Sorry - I saw that it failed - but I could not find to Travis Logs;(.

[pme123]

Thanks for merging. Are there nightly releases - or is there a release plant with this fix?

[eed3si9n]

I guess 0.13.0 at some point? It would be good to get a new ST4 for antlr/stringtemplate4#254 when it comes out.

0.13.0-M1 released

[PashoQ]

Is it possible to use version 0.13.0-M1 together with sbt new command?
