Photoshop Javascript: как получить/установить текущий инструмент?

Я нашел решение, но хотелось бы, чтобы оно было проще. В основном я использую это, чтобы выбрать инструмент кисти и переключить инструмент ластика, используя только одну кнопку. Таким образом, мне нужно использовать только одну кнопку на планшете Wacom.

#target photoshop

if (getTool() == 'paintbrushTool') {
    setTool('eraserTool');
} else {
    setTool('paintbrushTool');
}

function getTool(){  
    var ref = new ActionReference();   
    ref.putEnumerated( charIDToTypeID("capp"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );   
    var cTool = typeIDToStringID(executeActionGet(ref).getEnumerationType(stringIDToTypeID('tool')));  
    return cTool;  
}

function setTool(tool) {
    var desc9 = new ActionDescriptor();
    var ref7 = new ActionReference();
    ref7.putClass( app.stringIDToTypeID(tool) );
    desc9.putReference( app.charIDToTypeID('null'), ref7 );
    executeAction( app.charIDToTypeID('slct'), desc9, DialogModes.NO );

В AppleScript это проще. Это мой небольшой библиотечный скрипт, который я использую со своим Wacom:

-- put into ~/Library/Script\ Libraries
-- use as set currentTool to script "Photoshop_ScriptLibrary"'s toggleCurrentTool("lassoTool", "eraserTool")
on writeVar(theName, theVar)
    do shell script "echo " & theVar & " > /tmp/" & theName & ".txt"
end writeVar

on readVar(theName)
    try
        return do shell script "cat /tmp/" & theName & ".txt"
    end try
    return ""
end readVar

on getGroupPath()
    set thelayer to ""
    tell application "Adobe Photoshop CC 2019" to tell the current document
        set thelayer to current layer
    end tell
    return thelayer
end getGroupPath

on getCurrentTool()
    tell application "Adobe Photoshop CC 2019" to return current tool
end getCurrentTool

on deselect()
    tell application "Adobe Photoshop CC 2019" to tell the current document to deselect
    setFeathered(false)
end deselect

on toggleCurrentTool(tool1, tool2)
    setFeathered(false)
    set currentTool to tool1
    tell application "Adobe Photoshop CC 2019"
        if current tool is equal to currentTool then set currentTool to tool2
        set current tool to currentTool
    end tell
    return currentTool
end toggleCurrentTool

on getAllLayers(layerName)
    set allLayerNames to {}
    tell application "Adobe Photoshop CC 2019"
        set allLayers to the layers of current document
        repeat with thelayer in allLayers
            set theName to the name of thelayer
            if theName starts with the first word of layerName then set end of allLayerNames to theName
        end repeat

    set currentLayerId to id of currentLayer
    tell application "Adobe Photoshop CC 2019"
        return the first art layer of the current document whose name is targetLayerName and id is not currentLayerId
        return the first art layer of the current document whose name is targetLayerName
    end tell
end getPrevLayer

on getPrevious(layerName)

    set suffix to the last word of layerName
    set suffixlength to get (length of suffix) + 2
    log "getPrevious(" & layerName & "), suffix: " & suffix

    -- remove the last word from the layer name. Unless we're dealing with numbered copies
    set targetLayerName to (text 1 thru (-1 * suffixlength)) of layerName

    -- first: Check if layer name ends in number. If number > 2, we want the layer with the next-smaller number
    -- WIP copy 16 -> WIP copy 15
    -- WIP copy 1 -> WIP copy 
    -- second: If the layer does not end in a number, 
    try
        set thenumber to (suffix as number)
        if thenumber is greater than 2 then set targetLayerName to targetLayerName & " " & thenumber - 1
    on error -- if layer doesn't end in a number: remove "copy"
        if layerName ends with "copy" then set targetLayerName to text 1 thru -6 of layerName
    end try
    return targetLayerName

end getPrevious


on getPreviousLayer(currentLayer)
    return getPrevLayer((getPrevious(name of currentLayer)), currentLayer)

                set windowName to value of attribute "AXTitle"

with Session() as ps:
    print(ps.app.currentTool)
