Include remote .js-file in script-file (and use it's variables)

'm trying to access a remote .jsfile within an inDesign script to use it's variables. I found functions for including js-files locally but haven't found a good way to include.

http://remote-site.com/test.js:

var testVar = "it works!";

myscript.js, including locally (working):

app.doScript(new File("/Users/Popmouth/test.js")); alert(testVar);

myscript.js, including locally including remotely (not working):

app.doScript(new File("http://remote-site.com/test.js")); alert(testVar);

Error message

I also found this snippet, this alert works (alerts the content of the file, i.e. "var testVar = "it works!;") but I don't know how to use the vars in my alert function below:

var HTTPFile = function (url,port) {
          if (arguments.length == 1) {
                    url = arguments[0];
                    port = 80;
          };
          this.url = url;
          this.port = port;
          this.httpPrefix = this.url.match(/http:\/\//);
          this.domain = this.httpPrefix == null ? this.url.split("/")[0]+":"+this.port :this.url.split("/")[2]+":"+this.port;
          this.call = "GET "+ (this.httpPrefix == null ? "http://"+this.url : this.url)+" HTTP/1.0\r\nHost:" +(this.httpPrefix == null ? this.url.split("/")[0] :this.url.split("/")[2])+"\r\nConnection: close\r\n\r\n";
          this.reply = new String();
          this.conn = new Socket();
          this.conn.encoding = "binary";
          HTTPFile.prototype.getFile = function(f) {
                    var typeMatch = this.url.match(/(\.)(\w{3,4}\b)/g);
                    if (this.conn.open(this.domain,"binary")) {
                              this.conn.write(this.call);
                              this.reply = this.conn.read(9999999999);
                              this.conn.close();
                    } else {
                              this.reply = "";
                    }
                    return this.reply.substr(this.reply.indexOf("\r\n\r\n")+4);;
          };
}



var hyle = new HTTPFile("http://remote-site.com/test.js ");
alert(hyle.getFile());
hyle.getFile();

Correct answer Trevor:

This one works from a real remote.

It's Mac only I'll see about Windows for the sake of compleatness

var remoteCode = 'https://gist.githubusercontent.com/Trevor-/a297b25e270c2e19d3ba12b5406212d9/raw/88837413a0d5a234ad257bfc63c79f3fb3f87a25/gistfile1.txt';
var script = app.doScript("do shell script \"curl 'remoteCode'\"".replace("remoteCode", remoteCode), ScriptLanguage.APPLESCRIPT_LANGUAGE);
// Set script args
app.scriptArgs.setValue("scriptArg1", "Hello");
// Set environmental vars
$.setenv("envVar1", "World");
// Run the "remote" script
app.doScript(script, ScriptLanguage.JAVASCRIPT);
// Share functions and vars
blah(testVar, 'bar');

I'm really not a PS guy but this should work on Mac

if (app.name !== 'Adobe Photoshop') {
    alert('Crash,for Adobe Photoshop only!')
}
var remoteCode = 'https://gist.githubusercontent.com/Trevor-/6a02d8cb49bbfeb9822f061dea300bc1/raw';
// this function is nicked from // https: //forums.adobe.com/thread/2364797
function getSystemCommandStdout(command) {
    var stdout = "";
    var tempFile = new File(Folder.temp + "/temp.txt");
    app.system(command + " > " + tempFile.fsName);
    if (tempFile.open("r")) {
        stdout = tempFile.read();
        tempFile.close();
        tempFile.remove();
    }
    return stdout;
}
var result = getSystemCommandStdout("curl 'remoteCode'".replace("remoteCode", remoteCode));
// Set script args dosn't work on PS so just using setenv
$.setenv("envVar1", "Hello");
// Set environmental vars
$.setenv("envVar2", "World");
// Run the "remote" script
eval(result);
// Share functions and vars
blah(testVar, 'bar');

Note that after editing the gist it's getting a new URL, probably there's a simple work around

Edit 2: Changed the above seems to be be corrects and I changed the URL to the shorter form.


Yep if we just include the basic URL it should work with the updates

OK here's part one of the demo

var script= [
            'var testVar = "foo";',
            'var scriptArg1 = app.scriptArgs.getValue("scriptArg1");',
            'var envVar1 = $.getenv("envVar1");',
            'function blah(bar, baz){',
            'var result = bar + " " + baz;',
            'alert(result);}',
            'blah(scriptArg1, envVar1)'
            ].join('\n');
// Set script args
app.scriptArgs.setValue("scriptArg1", "Hello");
// Set environmental vars
$.setenv("envVar1", "World");
// Run the "remote" script
app.doScript(script,ScriptLanguage.JAVASCRIPT);
// Share functions and vars
blah(testVar, 'bar');

For now we'll use a local "remote" script but the idea will be exactly the same once you have curled it.

You can see 3 methods for passing the vars and args from one to the other.

I'll try paste a gist so I can demonstrate the real remote version.

use #include "path/to/file"

or $.evalFile(File('path/to/file')

Edit: sorry I missed the point, you need for remote.

as you're using InDesign and http you could just use a quick doScript (applescript) to curl the site that will retrieve the code then you can do another doScript to pass the arguments to the code in js. I'll see if I get a chance to paste some code later.
