Quick Start

from pathlib import Path

from vcti.pathformat import FormatRegistry, FormatIdentifier
from vcti.pathformat.descriptors import register_all_formats

# Register all built-in format descriptors
registry = FormatRegistry()
register_all_formats(registry)

# Identify a file
identifier = FormatIdentifier(registry)
results = identifier.identify_file_format(Path("data.h5"))

Individual descriptors

from vcti.pathformat.descriptors import get_hdf5_file_descriptor, get_cax_file_descriptor

registry = FormatRegistry()
registry.register(get_hdf5_file_descriptor())
registry.register(get_cax_file_descriptor())
