Treepace (tree pattern replace) is a Python library offering a concise, embeddable language for searching and replacing parts of tree structures.
The main features are:
- an intuitive API, similar to regex
- "one line per transformation" syntax - e.g.
tree.transform('item -> li') - bidirectional integration with the host language - transformations can execute Python code easily
- node values are real objects, not only strings
- thanks to node inheritance, nodes can react to changes which is useful for debugging and mapping to resources like GUI components
The simplest way is to install the package from PyPI: pip install treepace.
Alternatively, clone this repository and run: python setup.py install.
The tutorial is available in a form of IPython Notebook.
