How to use

You can find multiple examples in the examples directory and the package API in the documentation (still WIP). Here are a few examples.

import json

from yarrow import YarrowDataset

# say you have a yarrow file at path
file_path = "path/to/file.yarrow.json"

yar_set = YarrowDataset.parse_file(file_path)
# You now have a YarrowDataset !

# Add annotations
annot = Annotation(...) # see documentation for parameters
yar_set.add_annotation(annot)

# now save it somewhere else
with open("path/to/other/file.yarrow.json", "w") as fp:
    json.dump(yar_set.pydantic().dict(), fp, default=str)
