ioCSV v 0.67 (release)

Can Koluman, PhD Candidate, City, University of London, Department of Computer Science

A simple CSV (comma separated values) io Library in Scala https://github.com/cankoluman/ioCSV

Also available at https://search.maven.org/artifact/com.cankoluman/ioCSV For Maven, Groovy DSL, Kotlin DSL, Scala SBT, Ivy, and others.

News

Version 0.67 uses Scala 3.2.0. Also, the project now is IDE independent. Maven is sufficient to run it, even from a bash shell.

Introduction

This is a very lightweight csv (comma separated values) exporter implementation. The to be exported data is wrapped in a Frame[A] structure, which is passed to the csvRead(source: String, gZip: Boolean): Frame[A] or csvWrite(source: Frame[A], target: String, gZip: Boolean, append: Boolean): Unit methods. At the moment, we only have read / write for [A] = Vector[Vector[B]] via the VectorToCsv class. More info in the comments. The implementation will grow slightly over time.

Customizables

  • Headers: true / false, Frame.header: Option[Vector[String]]
  • Separator: Char
  • Encoding: Codec, e.g. Codec(StandardCharsets.UTF_8)
  • Gzip: true / false (when reading from / writing to a file)
  • Append: true / false (when writing to a file)

Dependencies

  • Scala
  • Scala Library
  • Scalatest 3
  • Scalatestplus:mockito 4-5_3
  • Mockito Core

TO DO

  • Add csv io for transposed Vector[Vector[A]]
  • Add csv io for ListMap[String, Vector[A]]
  • Add csv io for DenseMatrix[A] (Breeze)
