Paths.append() broken?

[Mark (Mark Frömberg aka Mark2Mark)]

myPaths = Layer.paths # also with `.__copy__()`
print myPaths
Layer.paths.append(myPaths)

fails:

layer.paths.append(myPath)
  File "GlyphsApp/GlyphsApp/__init__.py", line 2181, in append
ValueError

Builds 1137 and 1139

Any ideas?

You cannot append a list of paths. What you want is called .extend(). Type help(list). and you will amongst other things see this:

 |  extend(...)
 |      L.extend(iterable) -- extend list by appending elements from the iterable

And you probably want to make a .copy() of the paths before. You may end up iterating through your paths and do something like Layer.paths.append(myPath.copy())

The append method was wrong before. I fixed it and added the .extend() method.

You cannot append a list of paths.

true. But as Georg now wrote, it worked before
I dind’t make the copy here for the example. In real life I’m not even appending this layer’s paths

@mekkablue @GeorgSeifert Thanks for the quick feedback, I’ll change it now.
