Also, I would suggest to use the LastLogEntry action from xbytor's XTools to "clean" the ScriptingListener code.
For instance it turns this blob:
var idMk = charIDToTypeID( "Mk " );
var desc2 = new ActionDescriptor();
var idNw = charIDToTypeID( "Nw " );
var desc3 = new ActionDescriptor();
var idNm = charIDToTypeID( "Nm " );
desc3.putString( idNm, """myCopy""" );
var idMd = charIDToTypeID( "Md " );
var idBlnM = charIDToTypeID( "BlnM" );
var idDrkn = charIDToTypeID( "Drkn" );
desc3.putEnumerated( idMd, idBlnM, idDrkn );
var idLyr = charIDToTypeID( "Lyr " );
desc2.putObject( idNw, idLyr, desc3 );
var idUsng = charIDToTypeID( "Usng" );
var idArSl = charIDToTypeID( "ArSl" );
var idSlct = charIDToTypeID( "Slct" );
desc2.putEnumerated( idUsng, idArSl, idSlct );
var idCpy = charIDToTypeID( "Cpy " );
desc2.putBoolean( idCpy, true );
executeAction( idMk, desc2, DialogModes.NO );
into this nicer function:
function ftn1() {
function cTID(s) { return app.charIDToTypeID(s); };
function sTID(s) { return app.stringIDToTypeID(s); };
var desc2 = new ActionDescriptor();
var desc3 = new ActionDescriptor();
desc3.putString( cTID('Nm '), """myCopy""" );
desc3.putEnumerated( cTID('Md '), cTID('BlnM'), cTID('Drkn') );
desc2.putObject( cTID('Nw '), cTID('Lyr '), desc3 );
desc2.putEnumerated( cTID('Usng'), cTID('ArSl'), cTID('Slct') );
desc2.putBoolean( cTID('Cpy '), true );
executeAction( cTID('Mk '), desc2, DialogModes.NO );
};
Even if it's time consuming - in fact not that much using a text editor which supports multiple cursors like SublimeText - I use to "translate" all charIDs to stringIDs since they're more meaningful to me:
$.writeln(typeIDToStringID(charIDToTypeID('Nm '))); // name
$.writeln(typeIDToStringID(charIDToTypeID('Md '))); // mode
$.writeln(typeIDToStringID(charIDToTypeID('BlnM'))); // blendMode
$.writeln(typeIDToStringID(charIDToTypeID('Drkn'))); // darken
$.writeln(typeIDToStringID(charIDToTypeID('Nw '))); // new
$.writeln(typeIDToStringID(charIDToTypeID('Lyr '))); // layer
$.writeln(typeIDToStringID(charIDToTypeID('Usng'))); // using
$.writeln(typeIDToStringID(charIDToTypeID('ArSl'))); // areaSelector
$.writeln(typeIDToStringID(charIDToTypeID('Slct'))); // selectionEnum
$.writeln(typeIDToStringID(charIDToTypeID('Cpy '))); // copy
$.writeln(typeIDToStringID(charIDToTypeID('Mk '))); // make
Finally you can further manipulate the "cleaned" output with stringIDs, for instance this way:
function duplicateLayer(layerName, blendMode) {
function s2t(s) { return app.stringIDToTypeID(s) }
var d1 = new ActionDescriptor();
var d2 = new ActionDescriptor();
d2.putString(s2t("name"), layerName);
d2.putEnumerated(s2t("mode"), s2t("blendMode"), s2t(blendMode));
d1.putObject(s2t("new"), s2t("layer"), d2);
d1.putEnumerated(s2t("using"), s2t("areaSelector"), s2t("selectionEnum"));
d1.putBoolean(s2t("copy"), true);
executeAction(s2t("make"), d1, DialogModes.NO);
};
Over time, patterns start to appear and it gets less ugly than expected. Even if I still fail 1 out of 3 or 4 times with ActionManager, I'd say that it's a puzzle that I enjoy solving!
Besides, lot of people have already covered the basics (layers, layersets, etc) in the past so I'd first look for information in the forums - chances are that you'll find there what you need.
Also, be aware that ActionManager code is usually faster than DOM equivalent - especially when looping through layers - because you can extract from the each layer's Descriptor exactly the chunk of information you're interested into, while DOM as far as I know always include stuff like histogram values etc, which slow down the execution.
