Streaming JSON data into Max

August 20, 2013 | 9:42 am


So I have some data within a JSON package that I’d like to stream into Max. I then intend to manipulate the data in Max. Are there any objects that enable this? If not, does any body have any suggestions as to how to go about achieving this?

I just did this in a very brute-force way; reading through the file line-by-line and unpacking/parsing. That was lame, I wouldn’t recommend it.

JavaScript is the obvious solution; I’ll see if I can put that together.

Something like this should work:

function readlines(s)
var f = new File(s);
var i,a,c;

if (f.isopen) {
while ((a=f.readline()) && i<10) { // returns a string
var parsed = JSON.parse(a);
outlet(0, + " " + parsed.value);
} else {
post("could not open file: " + s + "\n");

The [dict] object can read and write json files…

Hi mzed – re: your post on putting together a way to use javascript for reading json data – have you made anything that can do this yet or should i use the [dict] object as suggested at the end of this thread?

thanks anom

Using the dict object with Javascript can probably do everything you want. There’s a lot of information in the documentation and on the forums.

This is solved with different approaches now, choose yours.
Password for file is "noleak"

OK here without windows node setup batch, so that forum security is ok.
No more password is needed, especially if you are not interested in the nodejs part of the solution.

The website got updated!
The setup pages are greatly simplified
There is the preview of the webdemo

In your case you only care about tcpigola, ignore node and tcpigolo.
This will work untill you have somthing sending ascii encoded JSON via udp to your max.
