implicit StreasmReader

[Alexandre Masselot]

Hello 

I really like the idea of rapture.

Nevertheless, I hit a wall with the hello world example

import rapture.core._

import rapture.uri._

import rapture.json._

import rapture.io._

import rapture.fs._

import rapture.net._

import rapture.core.strategy.throwExceptions

import platform.posix

import Encodings.`UTF-8`

val url: HttpUrl = (Http / "rapture.io" / "sample.json")

url.slurp[Char]

Returns:

Error:(14, 11) Cannot find implicit StreamReader for rapture.net.HttpUrl resources. rapture.net.HttpUrl resources can only be read if a StreamReader implicit exists within scope.

url.slurp[Char]

Error:(14, 11) not enough arguments for method slurp: (implicit accumulatorBuilder: rapture.io.AccumulatorBuilder[Char], implicit eh: rapture.core.ExceptionHandler, implicit sr: rapture.io.StreamReader[rapture.net.HttpUrl,Char], implicit mf: scala.reflect.ClassTag[Char])eh.![accumulatorBuilder.Out,Exception].

Unspecified value parameters sr, mf.

url.slurp[Char]

Thanks for the help

Thanks, Alex!

And sorry for the delay in responding.

It looks like you're using the 0.9.x version, and it can't find an implicit character encoding within scope. But you're importing Encodings.`UTF-8`!

In 0.9.x, the encodings in the `Encodings` object are not implicit. So you need to define the encoding using:

  implicit val enc = Encodings.`UTF-8`

Once I get the 0.10.0 modules released, you'll be able to import an encoding using:

  import encodings.`UTF-8`

(Note the lower-case 'e'.)

Cheers,
Jon
