what am I doing wrong? ```val path = "/home/elect/...

what am I doing wrong?

val path = "/home/elect/IdeaProjects/scifio-lifesci/test.sdt".toPath()
println(HostFileSystem.exists(path))
println(HostFileSystem.source(path).buffer().buffer.size)

> true
> 0
but test.sdt is not empty..

I have my logic expecting a Buffer, that's what I understood is something I can "consume" (I need to read sequentially and sparse)

You need to read HostFileSystem.source(path).buffer() . The following will give you everything in memory

HostFileSystem.source(path).buffer().readUtf8()
HostFileSystem.source(path).buffer().readByteArray()

[elect]

exploring right now with BufferedSource

[mbonnin]

You can also read byte by byte:

HostFileSystem.source(path).buffer().apply {
  readByte()
  readByte()
}

[mbonnin]

etc...

[mbonnin]

You probably need to read in a loop:

while(!bufferedSource.exhausted()) {
  // read stuff
}

[mbonnin]

Depends your use case

If you want a good video about okio,

this video▾

is pretty cool

thanks for that, I saw the three presentations suggested on the website, but this wasnt there!

[mbonnin]

Ah, might be worth adding it, it's pretty cool with animated marbles and all 🙂

[elect]

yep

Then BufferedSource is the perfect fit, it should have all the readInt , readShort , etc..

[elect]

exactly
