Some Scala utilities

Version Matrix

tmmUtils

Continuous Integration Maven Central

A bunch of Scala utilities I've found myself writing that I haven't (yet) decided to spin out into their own projects.

val tmmUtilsVersion = "0.7.0"

libraryDependencies += "au.id.tmm.tmm-utils" %% "tmm-utils-cats"               % tmmUtilsVersion        // Cats utilities
libraryDependencies += "au.id.tmm.tmm-utils" %% "tmm-utils-circe"              % tmmUtilsVersion        // Circe hashing
libraryDependencies += "au.id.tmm.tmm-utils" %% "tmm-utils-errors"             % tmmUtilsVersion        // Errors
libraryDependencies += "au.id.tmm.tmm-utils" %% "tmm-utils-syntax"             % tmmUtilsVersion        // Syntax utils
libraryDependencies += "au.id.tmm.tmm-utils" %% "tmm-utils-testing-core"       % tmmUtilsVersion % Test // Test utilities
libraryDependencies += "au.id.tmm.tmm-utils" %% "tmm-utils-testing-cats"       % tmmUtilsVersion % Test // Cats instances for tests
libraryDependencies += "au.id.tmm.tmm-utils" %% "tmm-utils-testing-scalacheck" % tmmUtilsVersion % Test // Scalacheck instances for tests

Cats

Some utilities for interaction with the cats-core library

Errors

Some type aliases and extension methods for dealing with types like Either[Throwable, A].

Circe

Some utilities relating to circe

Testing

  • JreVersionDependentFlatSpec, which provides utilities for ignoring tests based on the Java version
  • au.id.tmm.utilities.testing.syntax, which provides syntax to replace the old right.get method on Either
  • A set of ADTs that might be useful as test data (Animal, Fruit, CoinToss, Planet and TrafficLight)

Syntax

Some general syntax extensions.

Tuple syntax

import au.id.tmm.utilities.syntax.tuples._

val tuple: String -> Int = "hello" -> 5

val tuples: List[String -> Int] = List(
  "hello" -> 1,
  "world" -> 2,
)
