Easy navigation within nested data of mappings (dict, ...) and sequences (list, ...). Easy access of values via single keys within these nested data structures. Enables different (human accessable) representation of nested data structures.
augmentedtree enhances mappings and sequences (targeted for python
dictionaries and lists) preserving their native behavior and access.
The enhancement comes with getting values by single keys, human readable
viewing, selecting and setting multiple values/items within the nested
data at once, or-conditional selection of values/items. Also this package
intends to prepare the nested data for pyQt. The augmentation provides
methods and properties to be used for a

Installing the latest release using pip is recommended.

The major purpose of augmentedtree is to retrieve quickly specific value(s) from a deep nested data featuring:
- unix filename pattern
- regular expressions
- or-conditional selection
The targeted usage is to be able to write the following kind of code
# code where the nested data comes from ... # gathering parameters with AugmentedTree(nested_data) as tree: # simple selection first_value = tree.select("something", "here") last_value = tree.select("something", "there")[-1] a_slice_of_values = tree.select("a", "l?t", "of")[3:6] # selection with refinement selection_of_values = tree.select("also/a", "lot", "of") narrowed_down = selection_of_values.where("this", "or", "that")[ALL_ITEMS] ... if not tree.all_selections_succeeded: # break, exit or reacting to some value are not there ... # code which is working with requested parameters ...
