app.doProgress() and other undocumented app methods

[DBarranca]

Hi,

I was playing with the ExtendScript reflection interface and I've run into few app's methods that I've no use for, and to the best of my knowledge aren't documented, i.e.

app.doForcedProgress()
app.doProgress()
app.doProgressSegmentTask()
app.doProgressSubTask()
app.doProgressTask()
app.updateProgress()

Does anybody have any clue about them?

Thank you,

Davide Barranca

I don't know anything about them. But, if your really curious, you should be able to use the Reflection api determine what arguments these methods require.

I just checked Adobe's scripts and don't see them used anywhere.

Hi X,

thank you! How do I inspect the arguments? I've been using just this:

function prop (f) {
    $.writeln (f.reflect.name);
    var props = f.reflect.properties;
    var array = [];
    for (var i = 0; i < props.length; i++) {
        try {array.push (props.name + ": " + f[props.name])} catch (_){} array.sort ();
    }
    $.writeln (array.join ("\r"));
}
function meth (m) {
    var props = m.reflect.methods.sort(); $.writeln ("\rMethods");
    for (var i = 0; i < props.length; i++) {
        $.writeln (props.name);
    }
}
app.meth()

How do I inspect the arguments? I've been using just this:

The methods ReflectInfo object have an 'arguments' property which are also ReflectInfo objects which have all the details you'll need.

doProgress (progressString, javaScriptString);

Performs a task with a progress bar. Other progress APIs must be called periodically to update the progress bar and allow canceling. The progressString parameter is the string to show in the progress window, the javaScriptString parameter is the string to execute.

JavaScript Guide 2015 have some new JSX features:

1) app.currentTool: "The name of the current tool selected".

2) app.toolSupportsBrushes(): "Returns true if the specified tool supports brushes".

3) app.doProgress() [and many related methods]: "Performs a task with a progress bar".

Good find, Nemo. It would be nice if the had a ChangeLog for the PDFs.

Also, this progress bar looks like it will be difficult to retrofit into existing scripts.

Thanks nvkzNemo‌! Your answer more importantly has showed me that I've kept looking at the CC2014 JS scripting reference and not the CC2015... too bad!

xbytor2‌, I've tried but unsuccessfully to use it:

app.reflect.methods['doProgress'].arguments[0] // undefined is not an object
