TAR reader and writer (ustar, PAX, GNU extensions) for the koni_archive ecosystem.

koni_tar

TAR reader + writer (ustar, PAX, GNU extensions) for the koni_archive ecosystem. Pure Dart, runs everywhere Dart runs including the web (dart2js and dart2wasm).

Most applications should depend on the koni_archive facade, which registers this format automatically:

import 'package:koni_archive/io.dart';

final archive = await openArchiveFile('comics.cbt'); // format auto-detected
final page = archive.glob('*.png').first;
await for (final chunk in archive.openRead(page)) {
  // bounded-memory streaming
}

Depend on koni_tar directly only to build a custom format registry:

import 'package:koni_archive_core/koni_archive_core.dart';
import 'package:koni_tar/koni_tar.dart';

final registry = ArchiveFormatRegistry([const TarFormat()]);
final reader = await registry.openReader(source);

Reading: ustar, PAX (per-file + global), GNU long names/links, v7, base-256 fields, all entry types as metadata. GNU sparse entries are detected and throw a typed error (deferred). Writing emits ustar with PAX extensions where needed, from streaming input, interop-verified against bsdtar. See doc/features.md for the full matrix and doc/notes.md for design decisions.
