v0.5.2 2023-05-17

Added

v0.5.0 2023-05-15

Fixed

  • with emscripten >= 3.1.28, the shim for ES6 builds in nodejs is no longer needed (see emscripten-core/emscripten#17915)
  • added malloc and free to the list of explicit exports for the Module (newer emscripten was optimizing them away)

Changed

  • POSSIBLY BREAKING: building as MAIN_MODULE=2 with POSITION_INDEPENDENT_CODE ON (to allow dynamic linking)
  • Using newer HDF5 version 1.12.2 libraries
  • compiled using Emscripten 3.1.28
  • simplified imports for tests to use "h5wasm" directly

Added

  • Plugins can now be used if they are compiled as SIDE_MODULE, by loading them into the expected plugin folder /usr/local/hdf5/lib/plugin in the emscripten virtual file system (might need the name of the plugin file to end in .so, even if it is WASM)

v0.4.11 2023-04-19

Fixed

  • all datasets and attributes are read out in little-endian order (closes #49)

Added

  • New method to overwrite slice of an existing dataset: Dataset.write_slice(ranges: Array<Array<number>>, data: any): void;
  • Method to delete an attribute from a dataset or group (can be used to update an attribute by deleting it then re-creating it)
    • Dataset.delete_attribute(name: str): number (returns non-zero value if it fails for some reason)
    • Group.delete_attribute(name: str): number
  • Ability to specify chunks and maxshape when creating dataset (to make a resizable dataset): Group.create_dataset(name: string, data: GuessableDataTypes, shape?: number[] | null, dtype?: string | null, maxshape?: (number | null)[] | null, chunks?: number[] | null): Dataset
  • New method to resize datasets (only works if chunks and maxshape were defined): Dataset.resize(new_shape: number[]): void

Changed

  • Metadata now includes chunks: Array<number> | null, information and maxshape: Array<number> | null

v0.4.10 2023-02-19

Added

  • Group.paths(): string[]; // returns a list of all link paths found below the group in the tree. (Use on root object to get all paths in the file)

v0.4.9 2022-12-21

Added

  • Group.create_soft_link(target: string, name: string): number; // creates a soft link in a group with name: name (target must be absolute path)
  • Group.create_hard_link(target:string, name: string): number; //
  • Group.create_external_link(file_name: string, target: string, name: string): number;

All of these return non-zero values on error. To create links with absolute path, just use e.g. File.create_soft_link(target_path, link_path);

v0.4.8 2022-12-05

Added

  • IIFE build at ./dist/iife/h5wasm.js, to support use in Firefox workers (which don't currently support ESM)
  • WORKERFS support in ESM/IIFE builds, for loading local files with random access instead of copying whole file into memory

v0.4.6 2022-08-04

v0.4.5 2022-08-04

Fixed

  • H5Create should only be called with access modes H5F_ACC_TRUNC (w) and H5F_ACC_EXCL (x)

Added

  • support for SWMR read with refresh on a dataset: e.g.
const file = new hdf5.File("swmr.h5", "Sr");
let ds=file.get("data");
ds.auto_refresh=true;
ds.shape;
// returns 12
ds.shape;
// returns 16 because dataset was updated with SWMR write
ds.value
// has size=16
