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);

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();

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');

Here's Windows InDesign version.

I like it as it returns the result of the powershell script to the jsx engine which has some nice potential to it.

// For InDesign Windows !!!!!
var remoteCode = 'https://gist.githubusercontent.com/Trevor-/a297b25e270c2e19d3ba12b5406212d9/raw/';
var vbs = [
    'Set shell = CreateObject("WScript.Shell")',
    'Set executor = shell.Exec("powershell.exe  -windowstyle hidden Invoke-WebRequest -Uri remoteCode | Select-Object -ExpandProperty Content")'.replace("remoteCode", remoteCode),
    'executor.StdIn.Close',
    'returnValue = executor.StdOut.ReadAll',
].join('\n');
var script = app.doScript(vbs, ScriptLanguage.VISUAL_BASIC);
// 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');

This one demonstrates sharing vars simply in both directions without needing environmental variables or ScriptArgs.

Works for both Mac and Windows on InDesign

See the gists Demo for running remote scripts on InDesign. Shares vars and arguments with "local" script. See 1st comment for link to …

P.s. The end!

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.

Trevor:

Legend

use #include "path/to/file"

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

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

Trevor:

Legend

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.
