I just figured out why the tests were failing for me. I have syck 
installed, and just realized that Horde calls syck, which outputs 
different YAML than Horde/Yaml does. When I disabled syck temporarily 
all of the tests pass.

FWIW, you might consider making your tests do round-trip tests like so:

$this->assertEquals($inputPhpStruct, load(dump($inputPhpStruct)))

Also you might consider an option to "disable" syck use and use this 
option for the tests to ensure that testing is actually testing the 
Horde/Yaml code!

Thanks for accepting the patch.

Committed, thanks; I don't see any tests fail, so I'm closing this... 
if you have a failing test for the extra \n, please comment and I'll 
reopen and/or fix.

I have written up a patch with some tests (attached).

I have the dumper side working, but something odd is happening on the 
loading side. There is an extra \n at the end. I am not sure why.... 
maybe you could figure that part out.

Well, you could supply a unit test, to help prove the patch was 
correct and not breaking anything else.

How is this still not fixed 1 yr later? I even supplied a patch! Very 
frustrating to remember i have to work around this bug every time I 
set up a new machine...

Is there anything I can do to further this?

I have run into a problem with dumping PHP arrays that contain "#" 
characters, which is a comment signifier in YAML. I have a proposed

There might be more cases, and I don't know if this breaks in the case 
of folded code, but it's a start for you hopefully. This is a pretty 
important bug I think because it really breaks YAML dumping if you 
have this character in a string, which is a common occurrence.
