Rapture is an evolving collection of useful libraries for solving common, everyday programming tasks, using advanced features of Scala to offer better type-safety through powerful APIs that all Scala developers, beginners and advanced users, should find intuitive.
Rapture consists of a number of modules, the most notable of which are:
- Core (
core) — a library of common utilities for other projects, notably modes and the
- [JSON](doc/json.md) (
json) — comprehensive support for working with JSON data
- XML (
xml) — comprehensive, but experimental, support for working with XML data
- I/O (
io) — I/O (network, filesystem) functionality and infrastructure
- I18n (
i18n) — simple, typesafe representation of internationalized strings
- CLI (
cli) — support for working with command-line applications and shell interaction
Themes in Rapture
The Rapture modules share a common philosophy that has evolved over time and experience. Here are a few of the philosophical themes crosscutting all of the Rapture modules.
- A primary goal of intuitive, readable APIs and minimal code repetition
- Extreme type-safety, with a goal to reduce the surface area of code exposed to runtime exceptions
- Thoroughly typeclass-driven design, for extensibility
- Fearless exploitation of all Scala features, where (but only where) it is appropriate
- Agnostic support for multiple, alternative implementations of many operations with pluggable backends
- Extensive, but principled, usage of implicits to configure and constrain operations
- Support for modes in most APIs; the ability to change how failures are handled through return types
Snapshots of Rapture are available for Scala 2.10 and 2.11 under the Apache

is the name of the module, as taken from the list above.
Development work to get most Rapture modules working on [Scala.JS](htp://www.scala-js.org/) is ongoing.

Rapture openly welcomes contributions! We would love to receive pull requests of bugfixes and enhancements from other developers. To avoid potential wasted effort, bugs should first be reported on the Github issue tracker, and it's normally a good idea to talk about enhancements on the Gitter channel before embarking on any development.
Alternatively, just send Jon Pretty (@propensive) a tweet to start a conversation.
