Nooooo! :p Can you think of anything different between when it works and when it doesn't? For example, you had more applications running / more CPU load when it didn't work? Have you tried breaking down the composition into smaller pieces to try to narrow down the problem?

Bodysoulspirit, the iTunes music library is in a special (Apple-specific) XML format called a property list — which is convenient for some purposes, but unfortunately not for locating items in the XML.

Possibly we could enable the Make Tree from XML node to detect if the XML is a property list, and if so, turn the keys into element names and the values into content.

Anyone else interested in using the iTunes file or other property lists in Vuo?

Jaymie commented on Jérôme Lanon's Bug Report, “Personal node disappear

Confirmed (and there still seem to be some problems in 1.2.6 alpha1). We'll work on getting this fixed.

In the meantime, if you go to Tools > Open User Modules Folder, you can see the subcomposition files and rename them without accents. You'll have to restart Vuo Editor to reload the subcompositions with their new names.

Jaymie commented on Kewl's Discussion, “atan2(y,x): x and y switched?

No, that's the usual way for atan2 to work — https://en.wikipedia.org/wiki/Atan2#Illustrations

As your illustration shows, 0 radians (0°) is at the point x=1, y=0 — but since it's standard for the arguments to atan2 to be y then x, you would call atan2(0,1) to get this value.

Similarly, for π/2 radians (90°), at the point x=0, y=1, you would call atan2(1,0).

I guess they put the arguments as y then x because the arctangent uses the ratio y/x.

Chris, you need quotes around part of the XPath expression — replace /diplomas/program[code=scan] with /diplomas/program[code='scan'].
