def traverse_obj(
Each of the provided `paths` is tested and the first producing a valid result will be returned.
The next path will also be tested if the path branched but no results could be found.
Supported values for traversal are `Mapping`, `Sequence` and `re.Match`.
- A value of None is treated as the absence of a value.
+ Unhelpful values (`{}`, `None`) are treated as the absence of a value and discarded.
The paths will be wrapped in `variadic`, so that `'key'` is conveniently the same as `('key', )`.
The keys in the path can be one of:
- `None`: Return the current object.
- - `str`/`int`: Return `obj[key]`. For `re.Match, return `obj.group(key)`.
+ - `set`: Requires the only item in the set to be a type or function,
+ like `{type}`/`{func}`. If a `type`, returns only values
+ of this type. If a function, returns `func(obj)`.
+ - `str`/`int`: Return `obj[key]`. For `re.Match`, return `obj.group(key)`.
- `slice`: Branch out and return all values in `obj[key]`.
- `Ellipsis`: Branch out and return a list of all values.
- `tuple`/`list`: Branch out and return a list of all matching values.
- `function`: Branch out and return values filtered by the function.
Read as: `[value for key, value in obj if function(key, value)]`.
For `Sequence`s, `key` is the index of the value.
+ For `re.Match`es, `key` is the group number (0 = full match)
+ as well as additionally any group names, if given.
- `dict` Transform the current object and return a matching dict.
Read as: `{key: traverse_obj(obj, path) for key, path in dct.items()}`.
@params paths Paths which to traverse by.
@param default Value to return if the paths do not match.
+ If the last key in the path is a `dict`, it will apply to each value inside
+ the dict instead, depth first. Try to avoid if using nested `dict` keys.
@param expected_type If a `type`, only accept final values of this type.
If any other callable, try to call the function on each result.
+ If the last key in the path is a `dict`, it will apply to each value inside
+ the dict instead, recursively. This does respect branching paths.
@param get_all If `False`, return the first matching result, otherwise all matching ones.
@param casesense If `False`, consider string dictionary keys as case insensitive.
@param traverse_string Whether to traverse into objects as strings.
If `True`, any non-compatible object will first be
converted into a string and then traversed into.
+ The return value of that path will be a string instead,
+ not respecting any further branching.
@returns The result of the object traversal.
If successful, `get_all=True`, and the path branches at least once,
then a list of results is returned instead.
- A list is always returned if the last path branches and no `default` is given.
+ If no `default` is given and the last path branches, a `list` of results
+ is always returned. If a path ends on a `dict` that result will always be a `dict`.
