Full Changelog: v0.7.9...v0.8.0

v0.7.9 2025-01-09

Fixed

• Added total_size to metadata for VLEN datasets before further processing, fixes #89

v0.7.8 2024-09-06

Added

• Add close_file method to Module API: close_file(file_id: bigint): number;

Fixed

• Fix accessing attributes of committed datatype with my_datafile.attrs.
• Fix calling get_attribute_names method of Module API on committed datatype.

Changed

• Mark optional parameters as such in the TypeScript declarations of the following H5Module methods: open, create_dataset, create_group, create_vlen_str_dataset and get_keys_vector.

v0.7.7 2024-08-28

Added

• A method to read metadata from committed datatypes in an HDF5 file

  • Datatype.metadata is a getter that returns the dtype metadata, in the same format (Metadata TypeScript interface) returned from Dataset.metadata

• Enable "track order" mode of HDF5 for attributes of Dataset, and (fields and attributes) of Group. When track_order == true for a Group, both fields and attributes keep their insertion order on read. For a Dataset, the attributes keep their insertion order when the flag is set.

  Note that the flag is not inherited, i.e. if an h5wasm.Group object is created with track_order = true, its sub-groups and contained Dataset objects will not have the flag enabled by default. The flag is added to the File constructor just to track order of immediate children of the root group.

  Changes three signatures in the h5wasm API:

  • h5wasm.File(filename: string, mode: ACCESS_MODESTRING = "r", track_order: boolean = false)
  • h5wasm.Group.create_group(name: string, track_order: boolean = false)

  • h5wasm.Group.create_dataset(args: {
      name: string,
      data: GuessableDataTypes,
      shape?: number[] | null,
      dtype?: string | null,
      maxshape?: (number | null)[] | null,
      chunks?: number[] | null,
      compression?: (number | 'gzip'),
      compression_opts?: number | number[],
      track_order?: boolean,
    })
    

  Also adds one method to the Module API:

  • open(filename: string, mode?: number, track_order?: boolean): bigint;
    (the default arguments are mode = H5F_ACC_RDONLY and track_order = false)

  and modifies the signatures of three existing methods in the Module API:

  • create_dataset
  • create_group
  • create_vlen_str_dataset
