anitomy-ng

A pure-Rust port of erengy/anitomy, an anime video filename parser, with Python bindings. No unsafe, no C dependencies.

[TaigaSubs]_Toradora!_(2008)_-_01v2_-_Tiger_and_Dragon_[1280x720_H.264_FLAC][1234ABCD].mkv

parses into release group, title, year, episode, resolution, video/audio codec, release version, and file checksum — see the examples below.

Status: conformance-tested against upstream's own bundled test data (the current C++ rewrite on the develop branch and the original, long-frozen master implementation), plus the anitopy Python port's fixtures. On each suite it scores at least as high as that suite's reference parser, run as a compiled/installed binary rather than judged from its source.

Install

Rust:

cargo add anitomy-ng

Python (wheels built via maturin):

pip install anitomy-ng

Usage

Rust:

let elements = anitomy_ng::parse(
    "[TaigaSubs]_Toradora!_(2008)_-_01v2_-_Tiger_and_Dragon_[1280x720_H.264_FLAC][1234ABCD].mkv",
    anitomy_ng::Options::default(),
);
for element in &elements {
    println!("{:?}: {}", element.kind, element.value);
}

Python:

import anitomy_ng

for element in anitomy_ng.parse(
    "[TaigaSubs]_Toradora!_(2008)_-_01v2_-_Tiger_and_Dragon_[1280x720_H.264_FLAC][1234ABCD].mkv"
):
    print(element.kind, element.value)

Both return an ordered list of elements (position in the filename, kind, and value); ElementKind/kind covers title, episode, season, release group, video/audio terms, resolution, checksum, and so on — see anitomy/src/element.rs for the full set.
