This project is not relevant anymore. Since version 3, quill has monix support in a separate quill-monix module.
Quill is great. Monix is great.
Let's bring the two closer together.
This library is in a very early stage of development:
- Only JDBC-based H2 support
- No tests at all.
Snapshot version is available, courtesy of JitPack

val ctx = new H2TaskJdbcContext(SnakeCase, "database")
case class User(name: String, age: Int)
// Plain queries return Tasks
val users: Task[List[User]] = ctx.run(ctx.query[User].take(5))

val delYounglings = ctx.run(ctx.query[User].filter(_.age <= 15).delete).void
// Since Tasks are lazy, transactions can be added on top of existing ones
val deleteJonAndGetRest = ctx.transaction {
for {
_ <- deleteJon
rest <- users
} yield rest
}
// Task-based context relies on `TaskLocal`, so local context propagation
// MUST be enabled
