# Filename Tool
|
||||
|
||||
TypeScript library for extracting metadata from media filenames, designed for the Meta Orbit ecosystem.
|
||||
|
||||
## Overview
|
||||
|
||||
Filename Tool parses media filenames to extract structured metadata such as titles, seasons, episodes, quality, languages, and other relevant information. It's designed to work with various naming conventions used in media files.
|
||||
|
||||
## Features
|
||||
|
||||
- **Title Extraction**: Identifies show/movie titles from filenames
|
||||
- **Episode & Season Detection**: Parses episode and season numbers in various formats
|
||||
- **Quality Detection**: Identifies resolution (1080p, 720p, 4K) and quality indicators
|
||||
- **Language Detection**: Extracts language codes and audio track information
|
||||
- **Release Group**: Identifies fansub/release group tags
|
||||
- **Format Support**: Handles multiple filename patterns and conventions
|
||||
- **Platform Agnostic**: Dual builds for Node.js and browser environments
|
||||
|
||||
## Installation
|
||||
|
||||
From the monorepo root:
|
||||
```bash
|
||||
pnpm install
|
||||
```
|
||||
|
||||
When using as a dependency:
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"@metazla/filename-tool": "workspace:*"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```typescript
|
||||
import { FilenameParser } from '@metazla/filename-tool';
|
||||
|
||||
// Parse a filename
|
||||
const result = FilenameParser.parse('[SubsPlease] Naruto - 01 (1080p) [12345678].mkv');
|
||||
|
||||
console.log(result);
|
||||
// {
|
||||
// title: 'Naruto',
|
||||
// episode: 1,
|
||||
// season: 1,
|
||||
// quality: '1080p',
|
||||
// releaseGroup: 'SubsPlease',
|
||||
// hash: '12345678',
|
||||
// extension: 'mkv'
|
||||
// }
|
||||
```
|
||||
|
||||
## Supported Filename Patterns
|
||||
|
||||
### TV Shows
|
||||
- `ShowName S01E01.mkv`
|
||||
- `ShowName - 01.mkv`
|
||||
- `[Group] ShowName - 01 (1080p).mkv`
|
||||
- `ShowName.S01E01.1080p.WEB-DL.mkv`
|
||||
|
||||
### Movies
|
||||
- `MovieName (2024) 1080p BluRay.mkv`
|
||||
- `MovieName.2024.1080p.BluRay.x264.mkv`
|
||||
- `[Group] MovieName (2024).mkv`
|
||||
|
||||
### Quality Detection
|
||||
- Resolution: `1080p`, `720p`, `2160p`, `4K`, `8K`
|
||||
- Source: `BluRay`, `WEB-DL`, `HDTV`, `DVDRip`
|
||||
- Codec: `x264`, `x265`, `HEVC`, `AV1`
|
||||
|
||||
### Language Detection
|
||||
- Audio languages: `eng`, `jpl`, `spa`, `fre`, etc.
|
||||
- Subtitle languages: `[eng sub]`, `[multiple subs]`
|
||||
- Dual audio: `[eng+jpl]`
|
||||
|
||||
## Architecture
|
||||
|
||||
### Build Configuration
|
||||
Built with `tsup` for dual output:
|
||||
- **Node.js**: `dist/index.js` (ESM) and `dist/index.cjs` (CommonJS)
|
||||
- **Browser**: `dist/index-browser.js` (ESM) and `dist/index-browser.cjs` (CommonJS)
|
||||
|
||||
### Pattern Matching
|
||||
Uses regex patterns and heuristics to handle various filename formats:
|
||||
- Episode number detection with multiple patterns
|
||||
- Title cleanup (remove tags, group names)
|
||||
- Quality and resolution parsing
|
||||
- Hash/CRC extraction
|
||||
|
||||
## Development
|
||||
|
||||
### Building
|
||||
|
||||
```bash
|
||||
# From monorepo root
|
||||
pnpm run build
|
||||
|
||||
# From package directory
|
||||
cd packages/filename-tool
|
||||
pnpm run build
|
||||
```
|
||||
|
||||
### Testing
|
||||
|
||||
```bash
|
||||
cd packages/filename-tool
|
||||
pnpm test
|
||||
```
|
||||
|
||||
Uses Vitest for unit tests with comprehensive filename pattern coverage.
|
||||
|
||||
## Integration
|
||||
|
||||
Used by:
|
||||
- **meta-mesh**: Primary metadata extraction from filenames
|
||||
- **meta-orbit**: Filename normalization for distributed queries
|
||||
- **meta-ui**: Display and search filename metadata
|
||||
|
||||
## Examples
|
||||
|
||||
### Anime Filenames
|
||||
```typescript
|
||||
const result = FilenameParser.parse('[HorribleSubs] Attack on Titan - 25 [1080p].mkv');
|
||||
// { title: 'Attack on Titan', episode: 25, quality: '1080p', releaseGroup: 'HorribleSubs' }
|
||||
```
|
||||
|
||||
### Movie Filenames
|
||||
```typescript
|
||||
const result = FilenameParser.parse('The.Matrix.1999.1080p.BluRay.x264-GROUP.mkv');
|
||||
// { title: 'The Matrix', year: 1999, quality: '1080p', source: 'BluRay', codec: 'x264' }
|
||||
```
|
||||
|
||||
### Multi-Episode
|
||||
```typescript
|
||||
const result = FilenameParser.parse('Show.Name.S01E01-E03.1080p.mkv');
|
||||
// { title: 'Show Name', season: 1, episodes: [1, 2, 3], quality: '1080p' }
|
||||
```

# Meta-Hash
|
||||
|
||||
Meta-Hash is a TypeScript library designed to monitor a specified folder and compute hashes for any new files detected within it. This library leverages an index system to avoid recomputing hashes if the program is restarted, ensuring efficiency and continuity in hash computation. The hashes are computed in the Content Identifier (CID) format, making them compatible with systems like IPFS (InterPlanetary File System).
|
||||
|
||||
## Features
|
||||
|
||||
- **Platform Agnostic**: Dual builds for Node.js and browser environments
|
||||
- **Efficient Hash Computation**: Computes hashes using multiple algorithms (SHA2-256, SHA1, MD5, SHA3-256, SHA3-384, CRC32)
|
||||
- **Persistent Indexing**: CSV-based index system tracks file hashes, sizes, and modification times
|
||||
- **CID Format**: Uses IPFS Content Identifiers (multiformat, multicodec, multihash)
|
||||
- **Worker Thread Support**: Node.js build can use worker threads for parallel hashing
|
||||
- **Incremental Hashing**: Only rehashes files when size or mtime changes
|
||||
- **Multiple Hash Types**: Supports all major cryptographic and checksum algorithms
|
||||
|
||||
## CID Format and Inspection
|
||||
|
||||
The Content Identifier (CID) is a label used to point to material in IPFS. It doesn't indicate where the content is stored, but it forms a kind of address based on the content itself. CIDs are used as a standard way of pointing to pieces of information. A single CID can represent a piece of content that is distributed across multiple systems.
|
||||
|
||||
The list of CID formats used in this project can be found at the following link:
|
||||
[Multicodecs Table](https://ipfs.io/ipfs/QmXec1jjwzxWJoNbxQF5KffL8q6hFXm9QwUGaa3wKGk6dT/#title=Multicodecs&src=https://raw.githubusercontent.com/multiformats/multicodec/master/table.csv)
|
||||
|
||||
To inspect the details of a CID, including its version, codec, multihash and more, you can use the CID Inspector tool. This tool allows you to enter a CID and it will break it down into its component parts and provide a detailed explanation of each part.
|
||||
|
||||
[CID Inspector Tool](https://cid.ipfs.tech/)
|
||||
|
||||
## Installation
|
||||
|
||||
This package is part of the Meta Orbit monorepo and uses pnpm workspaces.
|
||||
|
||||
From the monorepo root:
|
||||
```bash
|
||||
pnpm install
|
||||
```
|
||||
|
||||
When using as a dependency in other packages:
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"@metazla/meta-hash": "workspace:*"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Usage of ComputeHashIndexCache
|
||||
|
||||
To integrate Meta-Hash into your application, follow these steps:
|
||||
|
||||
1. **Import the Library**: Import the necessary components from the library.
|
||||
|
||||
```typescript
|
||||
import { ComputeHashIndexCache, CID_ALGORITHM_NAMES } from "./folder-watch-hasher";
|
||||
```
|
||||
|
||||
2. **Initialize the Watcher**: Create an instance of `ComputeHashIndexCache`, specifying the path to the folder you want to monitor and the hash algorithms you wish to use.
|
||||
|
||||
```typescript
|
||||
//note that the csv file will be derived from the path provided into multiple files (one for each algorithm)
|
||||
const computer = new ComputeHashIndexCache("path/to/your/indexfile/index.csv", [CID_ALGORITHM_NAMES.sha256, CID_ALGORITHM_NAMES.sha1]);
|
||||
```
|
||||
|
||||
3. **Compute Hashes**: Invoke the `computeMissingHash` method for each file you wish to hash. This method will automatically check the index for existing hashes and compute missing ones.
|
||||
|
||||
```typescript
|
||||
let hash:MultiHashData = {};
|
||||
await computer.computeMissingHash("path/to/your/file.txt", hash);
|
||||
console.log(hash[CID_ALGORITHM_NAMES.sha256]);
|
||||
```
|
||||
|
||||
## Example of Index File
|
||||
|
||||
An example index file (`index-cid_sha2-256.csv`) is shown below, demonstrating how file paths, sizes, modification times, and computed hashes are stored:
|
||||
|
||||
```
|
||||
path,size,mtime,cid_sha2-256
|
||||
file.mkv,230265591,2023-01-17T18:53:37.692Z,baejbeif45glg263244x7cbjzyd3ssp5edzae7bxurzxjhnogazcwmj32wa
|
||||

## Platform-Specific Builds
|
||||
|
||||
### Node.js Environment
|
||||
|
||||
```typescript
|
||||
import { HashComputerIndexCache, CID_ALGORITHM_NAMES } from '@metazla/meta-hash';
|
||||
import path from 'path';
|
||||
|
||||
// With worker threads for parallel processing
|
||||
const packageEntryPath = path.dirname(import.meta.resolve("@metazla/meta-hash")) + "/worker.js";
|
||||
const hashComputer = new HashComputerIndexCache(
|
||||
'/path/to/index/folder',
|
||||
[CID_ALGORITHM_NAMES.sha256, CID_ALGORITHM_NAMES.sha1],
|
||||
packageEntryPath
|
||||
);
|
||||
|
||||
// Hash a file
|
||||
const hashes = {};
|
||||
await hashComputer.computeMissingHash('/path/to/file.mkv', hashes);
|
||||
console.log(hashes[CID_ALGORITHM_NAMES.sha256]);
|
||||
```
|
||||
|
||||
### Browser Environment
|
||||
|
||||
```typescript
|
||||
import { HashComputerIndexCache, CID_ALGORITHM_NAMES } from '@metazla/meta-hash/index-browser';
|
||||
|
||||
// Browser build (no worker threads, uses Web Crypto API where available)
|
||||
const hashComputer = new HashComputerIndexCache(
|
||||
'/virtual/index/path',
|
||||
[CID_ALGORITHM_NAMES.sha256]
|
||||
);
|
||||
```
|
||||
|
||||
## Architecture
|
||||
|
||||
### Build Configuration
|
||||
|
||||
Built with `tsup` for dual output:
|
||||
- **Node.js**: `dist/index.js` (ESM) and `dist/index.cjs` (CommonJS)
|
||||
- **Browser**: `dist/index-browser.js` (ESM) and `dist/index-browser.cjs` (CommonJS)
|
||||
|
||||
### Worker Thread Support (Node.js)
|
||||
|
||||
The Node.js build includes `worker.js` for parallel hash computation:
|
||||
```typescript
|
||||
// Automatic worker path resolution
|
||||
const workerPath = path.join(
|
||||
path.dirname(import.meta.resolve('@metazla/meta-hash')),
|
||||
'worker.js'
|
||||
);
|
||||
```
|
||||
|
||||
## Development
|
||||
|
||||
### Building
|
||||
|
||||
```bash
|
||||
# From monorepo root
|
||||
pnpm run build
|
||||
|
||||
# From package directory
|
||||
cd packages/meta-hash
|
||||
pnpm run build
|
||||
```
|
||||
|
||||
### Testing
|
||||
|
||||
```bash
|
||||
cd packages/meta-hash
|
||||
pnpm test
|
||||
```
|
||||
|
||||
Uses Vitest for unit tests.
|
||||
|
||||
## Integration
|
||||
|
||||
Used by:
|
||||
- **meta-mesh**: File content hashing for deduplication
|
||||
- **meta-orbit**: Content addressing for distributed storage
|
||||
- **meta-ui**: Browser-based file verification
|
||||
|
||||
## Performance
|
||||
|
||||
- **Index Cache**: Avoids rehashing unchanged files (checks size + mtime)
|
||||
- **Worker Threads**: Parallel hashing on multi-core systems (Node.js only)
|
||||
- **Streaming**: Hashes large files without loading into memory
|
||||
- **CSV Index**: Fast lookup and incremental updates

# Meta Interface
|
||||
|
||||
Shared TypeScript interfaces and types for the Meta Orbit ecosystem, providing type definitions used across all packages.
|
||||
|
||||
## Overview
|
||||
|
||||
Meta Interface is the foundational package that defines common TypeScript interfaces, types, and constants shared across the entire Meta Orbit monorepo. It has no dependencies and serves as the base layer for type safety.
|
||||
|
||||
## Features
|
||||
|
||||
- **Zero Dependencies**: Foundation package with no external dependencies
|
||||
- **Type Definitions**: Comprehensive TypeScript interfaces for metadata structures
|
||||
- **Shared Constants**: Common enums and constant values
|
||||
- **Platform Agnostic**: Works in both Node.js and browser environments
|
||||
- **Strict Typing**: Enables type safety across all packages
|
||||
|
||||
## Installation
|
||||
|
||||
This package is automatically available in the monorepo workspace:
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"@metazla/meta-interface": "workspace:*"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```typescript
|
||||
import type {
|
||||
HashMeta,
|
||||
FileMetadata,
|
||||
VideoType,
|
||||
MediaType
|
||||
} from '@metazla/meta-interface';
|
||||
|
||||
// Use interfaces for type safety
|
||||
const metadata: HashMeta = {
|
||||
cid_sha256: 'baejbei...',
|
||||
fileName: 'episode.mkv',
|
||||
sizeByte: '1024000',
|
||||
videoType: 'tvshow',
|
||||
season: '1',
|
||||
episode: '1',
|
||||
titles: { eng: 'Show Name' }
|
||||
};
|
||||
```
|
||||
|
||||
## Key Interfaces
|
||||
|
||||
### HashMeta
|
||||
Complete metadata structure for media files:
|
||||
```typescript
|
||||
interface HashMeta {
|
||||
// Content identifiers
|
||||
cid_sha1?: string;
|
||||
cid_sha256?: string;
|
||||
cid_md5?: string;
|
||||
cid_sha3_256?: string;
|
||||
cid_sha3_384?: string;
|
||||
cid_crc32?: string;
|
||||
|
||||
// File information
|
||||
fileName: string;
|
||||
extension?: string;
|
||||
sizeByte: string;
|
||||
fileType?: MediaType;
|
||||
|
||||
// Video metadata
|
||||
videoType?: VideoType;
|
||||
season?: string;
|
||||
episode?: string;
|
||||
originalTitle?: string;
|
||||
titles?: Record<string, string>;
|
||||
|
||||
// Classification
|
||||
anime?: string;
|
||||
genres?: string[];
|
||||
languages?: string[];
|
||||
tags?: string[];
|
||||
|
||||
// Paths
|
||||
privateFilePath?: string;
|
||||
publicFilePath?: string;
|
||||
}
|
||||
```
|
||||
|
||||
### VideoType
|
||||
```typescript
|
||||
type VideoType = 'movie' | 'tvshow' | 'anime' | 'documentary' | 'unknown';
|
||||
```
|
||||
|
||||
### MediaType
|
||||
```typescript
|
||||
type MediaType = 'video' | 'audio' | 'image' | 'document' | 'unknown';
|
||||
```
|
||||
|
||||
## Architecture
|
||||
|
||||
### Build Configuration
|
||||
Built with `tsup` for dual output:
|
||||
- **ESM**: `dist/index.js`
|
||||
- **CommonJS**: `dist/index.cjs`
|
||||
|
||||
### Package Structure
|
||||
```
|
||||
meta-interface/
|
||||
├── src/
|
||||
│ └── lib/
|
||||
│ ├── interfaces.ts # Core interface definitions
|
||||
│ ├── types.ts # Type aliases and unions
|
||||
│ ├── constants.ts # Shared constants
|
||||
│ └── index.ts # Public exports
|
||||
├── package.json
|
||||
└── tsconfig.json
|
||||
```
|
||||
|
||||
## Development
|
||||
|
||||
### Building
|
||||
|
||||
```bash
|
||||
# From monorepo root
|
||||
pnpm run build
|
||||
|
||||
# From package directory
|
||||
cd packages/meta-interface
|
||||
pnpm run build
|
||||
```
|
||||
|
||||
### Testing
|
||||
|
||||
```bash
|
||||
cd packages/meta-interface
|
||||
pnpm test
|
||||
```
|
||||
|
||||
Uses Mocha for type validation and interface tests.
|
||||
|
||||
## Used By
|
||||
|
||||
All packages in the monorepo depend on meta-interface:
|
||||
- **meta-hash**: Hash metadata structures
|
||||
- **meta-db**: Database record types
|
||||
- **meta-mesh**: File processing interfaces
|
||||
- **meta-orbit**: Network message types
|
||||
- **meta-ui**: UI component prop types
|
||||
- **filename-tool**: Parsing result types
|
||||
|
||||
## Dependency Flow
|
||||
|
||||
```
|
||||
meta-interface (foundation, no deps)
|
||||
↓
|
||||
All other packages depend on it
|
||||
```
|
||||
|
||||
This ensures:
|
||||
- Consistent types across the entire codebase
|
||||
- Single source of truth for interfaces
|
||||
- Type safety in all inter-package communication
|
||||
|
||||
## Contributing
|
||||
|
||||
When adding new interfaces:
|
||||
1. Add to appropriate file in `src/lib/`
|
||||
2. Export from `src/lib/index.ts`
|
||||
3. Document with JSDoc comments
|
||||
4. Ensure backward compatibility
|
||||
|
||||
This package is part of the Meta Orbit monorepo. See the root README for contribution guidelines.
