EzScala is a Scala library that helps write Scala easier.

It provides the following features:

• Extension methods
  • Operators
    • &&: AND operator for Truthy/Falsy value
    • ||: OR operator for Truthy/Falsy value
    • |: map left value to another value, by right function
      • For String: write string in UTF-8 encoding to a File or OutputStream
      • For Array[Byte], Iterator[Byte], Iterable[Byte], InputStream: write bytes in UTF-8 encoding to a File or OutputStream
    • |=: call right function, and return left value
    • |==: assert left value is true, or throw AssertionError
    • |>: alias of Iterable.map, Iterator.map
    • |>|: alias of Iterable.flatmap, Iterator.flatmap
    • |?: alias of Iterable.filter, Iterator.filter
    • |!=: alias of Iterable.tapeach, Iterator.tapeach
    • |!: alias of Iterable.foreach, Iterator.foreach
  • String:
    • bytes: get UTF-8 encoded bytes of String
    • find, find1, find2, find3: find substring by regular expression, and return found substring, or group 1/2/3
    • replace, replaceAll: replace substring by regular expression
    • file: use this string as file path to create a File object
    • http: use this string as URL to create a Http request HttpRequestData object. See IO section
  • Array[Byte]
    • string: UTF-8 decode to String
    • base64: Base64 encode to String
    • base64Url: Base64 encode to String, with URL safe
  • IO operations
    • AutoClosable
      • use: consume resource, and auto close it
    • File
      • bytes: return all bytes as a Array[Byte]
      • /: resolve child item in directory
      • parent: resolve parent directory
    • InputStream
      • bytes: return all bytes as a Array[Byte]
    • HttpRequestData:
      • header: add http request header to request
      • get, post: send HTTP Get/Post request, and return a HttpResponseWrapper
        • HttpResponseWrapper:
          • close: implementation of AutoClosable
          • statusCode: return status code of HTTP response
          • withStream: call a function with an InputStream of HTTP response
          • bytes: return all bytes as a Array[Byte]
          • text: return http response content as UTF-8 String
  • OS interaction
    • os.run: run a command line, check its return status, and return its output as String
    • os.sh: run a command line in shell, check its return status, and return its output as String
