v1.2.0

This mainly a backport of enhanced XPath & Pattern Matcher from 2.0.0, but also makes serialization dependencies options as well as removes the ability of TextFileSources to guess file encoding (and chardet dependency with it).

This release was entirely contributed by @dmmoeu. Thanks a lot!

🚀 Added

• ASTNode find and findall API's (backport from v2). See README for details.

✨ Changed

• pyyaml, orjson, msgpack are now optional dependencies. They can be installed via a new set of extras: msgpack, orjson, yaml or all. E.g.: pip install pyoak[msgpack]. DataClassSerializeMixin and hence ASTNode will have to/from_yaml and to/from_msgpack methods if the corresponding dependencies are installed. to/from_json methods are always available and use json if orjson is not installed.

⚠️ Breaking

• Pattern Grammar is now the same as v2 series. This is a breaking change, check out the README for details.
• TextFileSource no longer guesses file encoding. This is a breaking change, but it's a good thing. If you need to read a file with a specific encoding, read it yourself and pass the content as a string to the TextFileSource constructor's _raw attribute.

🐛 Fixed

• A couple of bugs in v2 pattern matcher were fixed in this release.
