Scripting: how to pass arguments to a script?

There are 2 scripts that can work both independently of each other, and together. To work together, they need to pass parameters to each other. Now I do it through app.putCustomOptions (but this is not very convenient).

Maybe it is possible to pass arguments when calling executeAction (AdobeScriptAutomation Scripts, desc) (since this is done, for example, by the Photoshop event subsystem)? I can write jsMs (javaScriptMessage) in the descriptor, but it may not be related to the arguments - I tried to put variables, objects, functions there, but the script of which I call with this jsMs does not see them in the arguments

I noticed ScriptListener creates 'javaScriptMessage' with """1""" value when in triggered code Window exists with OK button that then is pressed, and 2 when cancel button is pressed. So the same as win.show() returns.

I was not able to use those values for 'javaScriptMessage' to trigger script with clicked OK or Cancel button.

Probably it's only information for Photoshop listener, to note result of called script, but what for, I don't know.

How do you call a third-party script?
Could you give an example of what parameters you would like to pass to a third-party script?

originally i called the second script through:

function s2t(s) {return stringIDToTypeID(s)}
function t2s(t) {return typeIDToStringID(t)}

var pth = new File ("e:/_Output/test.jsx")

var desc = new ActionDescriptor()
desc.putPath( s2t ("javaScript"), pth)
desc.putString( s2t("javaScriptMessage"), "tried to put variables, objects, functions here" )
executeAction(s2t( "AdobeScriptAutomation Scripts" ), desc)

i need to pass a number of parameters: integer, strings, booleans and an array of objects that describe the set of actions, for example structure of settings object:

function initObj (s) 
{
        s.autoStart = true
        s.allowContinue = true
        s.saveMode = 0
        s.lastSavePath = ""
        s.fileFormat = 0
        s.flatten = false
        s.jpgQuality = 12
        s.override = false
        s.options = []
        s.doneCounter = -1
        s.continue = 0
}

where s.options are:

[{active:true, set:"test set", action:"test action 1", stop: false}, {active:false, set:"test set", action:"test action 2", stop: true}, {active:true, set:"test set", action:"test action 3", stop: false}]

on advice JJMack now I call the script through

executeAction (runtimeEventID, desc)

(accordingly, I pre-generated a unique runtimeEventID, in desc I put ActionDescriptor into which I write all the variables beforehand (for ease of processing, I convert the s.options array to a string) - accordingly, in the header of the script that is running, each variable is also declared and there is a corresponding settings object in the script body. A little cumbersome, but quite functional)

You can try this.

// script1.jsx

var param;

if (param == undefined) alert("Call without params")
else alert("Call with params=" + param.toSource())

// script1.jsx eof



// script2.jsx

call_script1();

function call_script1()
    {
    var param = new Object();

    param.x = 1;
    param.y = "2";
    param.z = [1, "2"];

    var script1_file = new File(new File($.fileName).parent.fullName + "/script1.jsx");
    if (script1_file.exists) $.evalFile(script1_file.fsName);
    }        

// script2.jsx eof

I use objects and common code goes into a .jsxinc file that is included in multiple scripts. That way I can pass variables to the common code or to an object parameter. No messaging required.

Thanks for the advice! But I don’t like when there are a lot of files in a folder, besides I need to not only transfer, but also store variables - for this I use the "registry" of Photoshop and app.putCustomOptions 🙂🙂
The problem is that both scripts can work not only together, but also independently of each other. If you use a common set of variables, then some of them will change in cases where this is not necessary - this forces me to duplicate variables (a separate set of variables for self-contained work and a separate set for starting from the second script).
The method proposed by JJMack is almost ideal for my case - the variables are transferred only for a specific instance of the script and you do not need to duplicate the variables or monitor their state since the main settings in the registry will not change.

You can avoid namespace collisions with objects. I write data to XML so its on disk, but typically my scripts don't need to talk directly to each other.

Use ScriptUI the create a dialog for the script so that you can set the parameters you want the script you use. I you do not want a dialog. You can code the script as a Photoshop plug-in. Plug-in have a dialog that can be bypassed by recording the plug-in in an action. When you record the Action the Script will displaye its dialog. However, the script will record the parameters you use in its dialog into the Action step being recorded. When the action is played the script will bypass displaying its dialog and use the parameters passed by the action. If you want to read the code of a Plug-in Script look in Photoshop Presets\Sctipts folders at "Fit Image.jsx". To look at scripts that work together look at "Image Processor.jsx" It pass parameters to "Fit Image.jsx" To resize image to fits area sizes you set in "Images Processor dialog" for the various resizes you set in its dialog for output file sizes.

Thank! I did not look very carefully at the Image Processor code - there really is a useful way to call another script by its identifier with parameter transfer (as if it had been called from the operation panel with pre-saved parameters). This is exactly what will help me solve my problem!
