**Functional programming toolkit aimed at taming the complexity of Tagless Final approach.** 

# Quick Start

## see [the docs on the microsite](https://tofu-tf.github.io/tofu)

## see the [examples in the `examples` directory](https://github.com/tofu-tf/tofu/tree/master/examples)

To use the whole utils pack just add to your `build.sbt`: 

```scala

libraryDependencies += "tf.tofu" %% "tofu" % "latest version in badge"

```

Of course, you can also specify an exact list of `tofu` modules that you want to add to your dependencies (used in place

of `"tofu"`):

* `tofu-kernel` for core independent utils

  * `tofu-kernel-cats-mtl` for interop between `tofu-kernel` and [Cats MTL](https://github.com/typelevel/cats-mtl)

* `tofu-core-*` for core utils (replace suffix `*` with `ce2` or `ce3` depends on which cats-effect version you use)

* `tofu-core-higher-kind` for higher kinded utils

* `tofu-concurrent` for concurrent utils

* `tofu-config` for config utils

* `tofu-data` for data utils

* `tofu-derivation` for derivation utils and [derevo](https://github.com/tofu-tf/derevo) annotations

* `tofu-doobie` for [Doobie](https://github.com/tpolecat/doobie) utils

* `tofu-enums` for [Enumeratum](https://github.com/lloydmeta/enumeratum) utils

* `tofu-env` for `Env` (a variation of a Reader Monad based on [Monix](https://github.com/monix/monix) Task)

* `tofu-fs2-interop` for interop with [fs2](https://github.com/functional-streams-for-scala/fs2)

* `tofu-streams` for streaming utils

* `tofu-logging` for the whole set of logging utils (derivation, layout, structured, util, interop)

  * `tofu-logging-derivation` for logging derivation only

  * `tofu-logging-layout` for logging layout only

  * `tofu-logging-structured` for logging structured only

  * `tofu-logging-util` for logging util only

  * `tofu-logging-refined` for interop between tofu-logging and [Refined](https://github.com/fthomas/refined) 

  * `tofu-logging-shapeless` for interop between tofu-logging and [Shapeless](https://github.com/milessabin/shapeless) tag

  * `tofu-logging-log4cats` for interop with [Log4Cats](https://github.com/typelevel/log4cats)

* `tofu-memo` for caching utils

* `tofu-observable` for `monix.reactive.Observable` utils

* `tofu-zio-interop` for interop with [ZIO](https://zio.dev) (core, logging)

  * `tofu-zio-core` for ZIO instances only

  * `tofu-zio-logging` for ZIO logging only
