go-ptn - Parse Torrent File Name

Extract media information from movie and tv series filename

A port of middelink/go-parse-torrent-name awesome library.

Extract all possible media information present in filenames. Multiple regex rules are applied on filename string each of which extracts corresponding information from the filename. If a regex rule matches, the corresponding part is removed from the filename. In the end, the remaining part is taken as the title of the content.

Why?

Online APIs by providers like TMDb, TVDb and OMDb don't react to well to search queries which include any kind of extra information. To get proper results from these APIs, only the title of the content should be provided as the search query where this library comes into play. The accuracy of the results can be improved by passing in the year which can also be extracted using this library.

This port assumes the files folllow the current (2022) formats, and puts less focus on older naming styles. This port fixed some bugs with file extentions (containter) and various title issues. It includes a test file which can easily be updated as a json file.

Usage

package main

import (
	"fmt"
	"github.com/razsteinmetz/go-ptn"
)

func main() {
	filename := "series.title.s01e03.720p.hdtv-GROUP.avi"
	info,_ := ptn.Parse(filename)
	fmt.Println(info)
}

// info has all the data you need

PTN works well for both movies and TV episodes. All meaningful information is extracted and returned together in a dictionary.
