μscala is a set of general purpose micro libraries written in Scala.
What can I find in here?
In this project you'll find a set of general purpose micro libraries written in scala.
List is as follows:
- i18n: message internationalization scala micro library with no dependencies for the JVM.
- resources: helps dealing with resources in the classpath, allowing null-safe access and listing resources from packages.
- result: a right biased union type that holds a value for a successful computation or a value for a failed one.
- result-async: A right biased union type that holds a value for an asynchronous/future successful computation or a value for a failed one.
- result-specs2: specs2 matchers for the result type
- retry: small utility that retries a computation until it is successful using a backoff algorithm (exponential backoff by default).
- timeout: class that allows to query if a specific amount of time has elapsed or not.
- url: immutable URL class with some useful methods to construct it, get the params, convert it to other types...
Sometimes the Scala/Java ecosystem forces you to include huge libraries when you only want to get a small piece of functionality. It's not strange to find projects that include Cats, Scalaz, Guava or Apache Commons (or all of them!) just because they want to use a simple piece of functionality from each of those projects.
The idea behind μscala is to create a set of very small libraries that offer some of the most common used functionality that is missing from the standard Scala & Java standard libraries.
It's important to note that μscala is not and will never be a replacement for any of the above libraries. They are excellent libraries that I use in lots of projects.
What defines a μ-library?
In order to be included in μscala, a library must fulfill the following requisites:
- Shall be composed by a single functionality (oversimplifying, 1 single file)
- Shall not have any external dependency, except for:
- Test libraries
- A maximum of 2 μ-libraries
- Shall cover a very common functionality
- Shall be well tested
- Shall be MIT licensed unless for licensing compatibility issues a different open source license is needed.
Can I contribute?
Yes, of course, any contribution is welcome. You can contribute either by:
- Adding a new μ-library
- Adding some function to an existing one
