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?

If I define my custom source generator it is executed in parallel with Twirl generator, not before or after. I haven't found a way to make one source generator dependent on another one. – Prothallus

Answer 1

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

pipelineStages := Seq(myPreProcessorTask, myTwirlTask)

Interestring. I'll try to use the same idea. – Prothallus
