Scaruby is not a thin layer of java.io but a thick layer of it. Users of Scaruby don't need to
know the detail of java.io. Instead, Scaruby provides the way to do file I/O independently.
- Builtin loan pattern
- Simple operation can be done by simple method call
- Base64 encode/decode
- Every SReader/Swriter can be used in
for-expression, which is implemented asforeachmethod. - Support reading text/binary content from SURL
- Minimize overloading! Instead, use type classes or default arguments
- Additional features will be added as needed
Now Scaruby supports Scala 2.11.X, Scala 2.12.X, and Scala 2.13.X.
Add the following lines to your build.sbt:
libraryDependencies += "com.github.scaruby" %% "scaruby" % "0.6"If you'd like to use SNAPSHOT version, add the following lines:
resolvers += "Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"
libraryDependencies += "com.github.scaruby" %% "scaruby" % "0.7-SNAPSHOT"and you can use Scaruby like the following:
Read from text file:
import com.github.scaruby._
val content = SFile.read("file.txt")Read lines from text file:
import com.github.scaruby._
val lines = SFile.readLines("file.txt")Read from binary file:
import com.github.scaruby._
val content = SFile.readBytes("files.bin")Base64 encode/decode:
import com.github.scaruby._
val input = "Hello, World!"
val encoded = SBase64.encode(input.getBytes("UTF-8"))
val decoded = new String(SBase64.decode(encoded), "UTF-8")
assert(input == decoded)Read from URL:
import com.github.scaruby._
val content = for {
r <- SURL("https://srad.jp/").openReader
} r.readAll
println(content)Calculate the average:
import com.github.scaruby.collection._
val seq = Seq(1.0, 2.0, 3.0)
assert(2.0 == seq.average)upward indexed loop (from 0.6-SNAPSHOT):
