Configrity README file
Configrity is a configuration library for Scala 2.9 or +. Configuration instances are immutable, thread-safe and allow functional design patterns, such as:
- Getting options to values
- Converting implicitly values via type-classes
- Reader monad
The API is now stable and covered by tests. However, as it is very young, it may contain some bugs.
import org.streum.configrity._ val config = Configuration.load( "server.conf" ) val hostname = config[String]("host") val port = config[Int]("port") val updatedConfig = config.set ("port",8080 ) upddatedConfig.save( "local.conf" )
- Automatic values conversions via type classes.
- Loading configurations from any source (File, InputStream, URL, etc.)
- Loading configurations from system properties and environment variables.
- Saving configurations to files.
- Interoperability with java properties.
- Hierarchical configuration blocks.
- Configuration chaining (such as to provide default values).
- Single import:
import org.streum.configrity._imports all you need.
- Access through reader monads
- Values can be lists (v0.7.0)
- Extra value converters: File, Color, URL, URI (v0.7.0)
includedirective is supported, adding compatibility with Akka and Configgy configurations files.
- Loading configurations from classpath/resources (v0.9.0)
- YAML format support (v0.10.0)
- More export/Import formats: INI, JSON, XML, apache, etc.
- Build configurations from command line arguments
Configrity depends on Scala 2.8.1 or newer.
While core features do not depend on external libraries, some modules may. In that case, the approriate dependencies will be automatically installed by sbt/maven.
The dependency line is:
"org.streum" %% "configrity-core" % "0.10.2"
Additional modules require addition dependency lines. Check the wiki for more information: https://github.com/paradigmatic/Configrity/wiki/Modules
From Maven, Buildr, Ivy, Grape and Grails
Follow the repository instructions.
From source (master branch)
To install Configrity you just need a working java installation (tested with JDK 1.6, but may work with 1.5) and SBT 0.11+:
$ git clone git://github.com/paradigmatic/Configrity.git $ cd Configrity $ sbt > test > doc > package
If you want to cross-build, you will need to generate adapters for Scala 2.8.x via sbt-scalashim:
$ sbt > project configrity-core > scalashim > project configrity > +test > +package
See the wiki: https://github.com/paradigmatic/Configrity/wiki
