Sorry for the late reply, been super busy at work. But this is exactly 
what I needed, thanks! I could tell makeSimpleTag() was a convenience 
function but for some reason I was having trouble finding where and how 
makeTagEntry was being used. I seem to have it working, when I run ctags 
with a QML file now it prints js functions and QML Objects, and if it 
finds their id it prints that as well.
Here's a sample of what it prints:
Item    main.qml    /^Item {$/;"    o
Timer createLibraryTimer    main.qml    /^        Timer {$/;"    o
Timer firstRunTimer    main.qml    /^        Timer {$/;"    o
Timer loadLibraryTimer    main.qml    /^        Timer {$/;"    o
Timer scanFoldersTimer    main.qml    /^        Timer {$/;"    o
testFunc1    main.qml    /^    function testFunc1(variable) {$/;" f
testFunc2    main.qml    /^        function testFunc2() {$/;"    f

Does that look about right?
One thing I notice is I don't see line numbers on output, is there an 
option I have to run ctags with to show the line numbers maybe?
