script-monad v0.0.3 Release Notes

Release Date: 2019-01-01 // over 5 years ago

  • 🚀 This release has some significant changes to type names and signatures. The good news is that these changes make the code simpler and more modular. The bad news is that it now uses the QuantifiedConstraints extension, available only in GHC >=8.6.

    • ➕ Added
      • liftScriptTT and liftHttpTT
    • 🔄 Changed
      • Most functions now have additional Monad and MonadTrans constraints.
      • ScriptT is now ScriptTT and takes the effect monad as an explicit type parameter. Now acts like a monad transformer transformer.
      • Script is now ScriptT and takes the effect monad as an explicit type parameter, reflecting its status as a monad transformer
      • HttpT is now HttpTT and takes the effect monad as an explicit type parameter. Now acts like a monad transformer transformer.
      • Http is now HttpT and takes the effect monad as an explicit type parameter, reflecting its status as a monad transformer
      • execScriptTM is now execScriptTT and does not take an explicit lift parameter, using the generic MonadTrans instance instead.
      • checkScriptTM is now checkScriptTT and does not take an explicit lift parameter, using the generic MonadTrans instance instead.
      • execHttpTM is now execHttpTT and does not take an explicit lift parameter, using the generic MonadTrans instance instead.
      • checkHttpTM is now checkHttpTT and does not take an explicit lift parameter, using the generic MonadTrans instance instead.
    • ✂ Removed
      • Script.lift, in favor of a generic MonadTrans instance
      • liftHttpT, in favor of a generic MonadTrans instance
      • execScriptT, execScript, checkScript, and checkScript, which use a pure evaluator. These are subsumed by ScriptTT where the base monad is Identity.
      • execScriptM and checkScriptM, which are subsumed by ScriptTT with the IdentityT transformer.
      • execHttpM and checkHttpM, which are subsumed by HttpTT with the IdentityT transformer.
