Thanks Michael,
That helped me find this page:
http://chapel.cray.com/docs/master/modules/standard/IO.html#i-o-overview
<http://chapel.cray.com/docs/master/modules/standard/IO.html#i-o-overview>
(Google is still not that friendly to Chapel, getting better) In this example:
var myFile = open("test-file.txt", iomode.r);
// create a reading channel starting at file offset 0
// (start and end offsets can be specified when creating the
// channel)
var myReadingChannel = myFile.reader();
var x: int;
// Now read a textual integer. Note that the
// channel.read function returns a bool to indicate
// if it read something or if the end of the file
// was reached before something could be read.
var readSomething = myReadingChannel.read(x);
I see that x is a primitive. Can you read JSON into an object or was that
blocked by existential questions? Good place to have existential questions: In
Chapel...
Is that sample application somewhere I can learn from it?
Thanks,
b
