Preprocessing of sbt-twirl templates

Question

I need to preprocess some Twirl templates in my sbt project. Is it possible to define a task in build.sbt that will run before Twirl plugin compiles its templates?

Answer 1

sbt-web allows the sequencing of the asset pipeline through pipelineStages:

pipelineStages := Seq(myPreProcessorTask, myTwirlTask)
