I discovered today that pretty much all current documentation of how to build anything in Halogen is targeting v4.0.0. I’ve gotten past the Bower awkwardness and am using Spago, as is apparently the recommended tool for today. However, I’d like to just “make something work” and the latest Halogen has breaking changes in it. For example, the changes to Halogen.Component.ChildPath, which appears to have completely changed, based on the notes I read for version 5. I’d like to be able to tell Spago to just use the older version of Halogen, for now. However, I can’t find documentation on how to pin a specific package version in spago.dhall anywhere. Can someone point me in the right direction? Thanks.
