Bug Fixes:
* Under certain conditions, some YAML changes were affecting unexpected nodes
which had identical original values.
* YAMLValueFormats.DEFAULT was identifying all CLI-supplied values as String
rather than their most-likely data-type.
API COMPATIBILITY WARNING:
Previous versions of the library returned only selected data nodes. Now,
instead of data nodes, NodeCoords objects are returned. This is necessary in
order to resolve Issue 44, which was caused by Python over-aggressively
optimizing memory, making non-String data nodes references to any other node
with the same value. This made changing exactly one of those data nodes
impossible because all nodes with the same original value would change with it.
Now, the NodeCoords class carries DOM tracking data along with each data
node making precise node changes possible. However, your queries will now
return this more complex additional data. In order to evaluate just the data,
please refer to this before-and-after example:
BEFORE:
for node in processor.get_values(yaml_path):
do_something_with(node)
AFTER:
for node_coordinate in processor.get_values(yaml_path):
do_something_with(node_coordinate.node)
If you need to recursively remove DOM tracking data from the results, a new
utility function is available: func.unwrap_node_coords(data). Note however
that you need that tracking data in order to change data within the DOM.
This does not affect the output of the sample command-line utilities.
