Augeas parses configuration files into a tree structure, which it exposes through its public API. Changes made through the API are written back to the initially read files. The transformation works very hard to preserve comments and formatting details. It is controlled by ``lens'' definitions that describe the file format and the transformation into a tree. z/Nathaniel McCallum <nathaniel@natemccallum.com>z�Jeff Schroeder <jeffschroeder@computer.org> Harald Hoyer <harald@redhat.com> - initial python bindings, packaging Nils Philippsen <nils@redhat.com> � N)� version_info)�reduce)� �utf8c C � | r| � t�S d S �N)�encode�AUGENC��st� r �(/usr/lib/python3/dist-packages/augeas.py�enc: � �r c C r r )�decoder r r r r �dec? r r c G s@ dd� dd� | D �D �}t dd� |d�}|s td| d ��|S ) z]Search for one of the libraries given as arguments and load it.

The returned paths are sufficiently qualified to make sure that they match exactly one node in the current tree. Path expressions use a very simple subset of XPath: the path 'path' consists of a number of segments, separated by '/'; each segment can either be a '*', matching any tree node, or a string, optionally followed by an index in brackets, matching tree nodes labelled with exactly that string. If no index is specified, the expression matches all nodes with that label; the index can be a positive number N, which matches exactly the Nth node with that label (counting from 1), or the special expression 'last()' which matches the last node with the given label. All matches are done in fixed positions in the tree, and nothing matches more than one path segment.r? r@ r z Error during match procedure!)r- r. r/ r3 r4 r �POINTERr5 r# r1 � aug_matchr rD �range�appendr �castrB rF � pythonapi� PyMem_Free)r6 rH �arrayrI �matches�ir r r �match� s, � ��� z Augeas.matchc C s� t |t�s td��| jstd��t�� }t�� }t�� }t�� }t�� }t�� }t�� }tj} t j � | jt |�| |�| |�| |�| |�| |�| |�| |�� } | dk rVt d��t|j�|j|j|j|j|j|jfS )ai Get the span according to input file of the node associated with PATH.

Which files to load and what lenses to use on them is specified under /augeas/load in the tree; each entry /augeas/load/NAME specifies a 'transform', by having itself exactly one child 'lens' and any number of children labelled 'incl' and 'excl'. The value of NAME has no meaning. The 'lens' grandchild of /augeas/load specifies which lens to use, and can either be the fully qualified name of a lens 'Module.lens' or '@Module'. The latter form means that the lens from the transform marked for autoloading in MODULE should be used. The 'incl' and 'excl' grandchildren of /augeas/load indicate which files to transform. Their value are used as glob patterns. Any file that matches at least one 'incl' pattern and no 'excl' pattern is transformed. The order of 'incl' and 'excl' entries is irrelevant. When AUG_INIT is first called, it populates /augeas/load with the transforms marked for autoloading in all the modules it finds.
