ihs29x

A simple spec-driven streaming ("SAX-style") parser for IHS 297 and 298 files, based on the specifications provided by twoninetyex. It handles 297 and 298 files in either fixed or comma delimited format. In accordance with my reading of the spec, it even handles intermixed formats within a single file, based on (sub-)file headers.

The only interesting function is ihs29x.stream_records, which may be called on an open file-like object in text mode.

Live documentation is available at https://derrickturk.github.io/ihs29x-python/docs/ihs29x.html.

Usage

For example, try:

import sys

from ihs29x import stream_records


def main(argv: list[str]) -> int:
    if len(argv) != 2:
        print(f'Usage {argv[0]} <298-or-297-file>', file=sys.stderr)
        return 2

    with open(argv[1]) as f:
        for r in stream_records(f):
            print(r)

    return 0


if __name__ == '__main__':
    sys.exit(main(sys.argv))
