parse-torrent-title

Extract media information from torrent-like filename

Originally based off of this JavaScript library.

Extract all possible media information from a filename. Multiple regex rules are applied on the filename, each of which extracts appropriate information. If a rule matches, the corresponding part is removed from the filename. Finally, what remains is taken as the title of the content.

Install

PTN can be installed automatically using pip.

$ pip install parse-torrent-title

Requirements

Requirements are optional. That being said, the regex library increases performance on Python 2 by more than 10x, so it might be worth installing with:

$ pip install -r requirements.txt

With Python 3, the default re module is faster than regex, so it will always be used regardless of installed requirements.

Why?

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

Examples

Movies, series (seasons & episodes), and subtitles can be parsed. All meaningful information is extracted and returned in a dictionary. Text which couldn't be parsed is returned in the excess field.

More examples (inputs and outputs) can be found looking through tests/files.

CLI

You can use PTN from your command line, where the output will be printed as JSON:

$ python cli.py 'Insecure.S04.COMPLETE.720p.AMZN.WEBRip.x264-GalaxyTV'

 {
     'title': 'Insecure'
     'encoder': 'GalaxyTV',
     'codec': 'H.264',
     'season': 4,
     'resolution': '720p',
     'network': 'Amazon Studios',
     'quality': 'WEBRip',
 }

For help, use the -h or --help flag:

$ python cli.py --help

This will provide a brief overview of the available options and their usage.

Raw info

The matches in the torrent name are standardised into specific strings, according to scene rules where possible - 'WEBDL', 'WEB DL', and 'HDRip' are all converted to 'WEB-DL', for example. 'DDP51' becomes 'Dolby Digital Plus 5.1'. ['ita', 'eng'] becomes ['Italian', 'English'].To disable this, and return just what was matched in the torrent, run:

PTN.parse('A freakishly cool movie or TV episode', standardise=False)

In the CLI, you can use the --raw flag:

$ python cli.py --raw 'A freakishly cool movie or TV episode'

Types of parts

The types of parts can be strings, integers, booleans, or lists of the first 2. To simplify this, you can enable the coherent_types flag. This will override the types described below according to these rules:

• title and episodeName will always be strings.
• All other non-boolean fields will become lists of the type they currently are. For example, language will always be a list of strings, and episode a list of episodes. This can be weird for some fields, but it avoids a lot of isinstance calls - just always use x in y and you should be fine.
• Boolean types will remain as booleans.

To enable this flag:

PTN.parse('An even cooler movie or TV episode', coherent_types=True)

In the CLI, you can use the --coherent-types flag:

$ python cli.py --coherent-types 'A freakishly cool movie or TV episode'

Contributing

Submit a PR on the dev branch. If you have changed the regex for a pattern, I can assume this is because you had a title that was being incorrectly processed, and your change fixes it. Please add the title to the test suite!

To add new titles to the tests, you have 2 options (the first is easier):

• Add the titles to tests/test_generator's main method (in add_titles()), and run it. When asked for input, type 's', and it will automatically add what's needed to files/input.json, files/output_raw.json, and files/output_standard.json. The fields encoder, excess, site, and episodeName don't always have to be correct - if they're giving you issues, or seem wrong, feel free to manually remove them from the output test files.

• Otherwise, you must add input torrent names to tests/files/input.json and full output json objects (with standardise=False) to tests/files/output_raw.json. Also add the standardised output to tests/files/output_standard.json, only including fields that are different from output_raw.json, along with title.

Additions to parse-torrent-name

Below are the additions that have been made to /u/divijbindlish's original repo, including other contributors' work. parse-torrent-title was initially forked from here, but a lot of extra work has been done since, and given that the original repo is inactive, it was unforked.

Updates on top of /u/roidayan's work

• Added standardisation of output strings.
• Added multi-language support.
• Added multi-episode support.
• Added a basic CLI.
• Added thread safety.
• Improved support for anime tv releases.
• Improved support for Indian releases.
• Added various fields (see field list above).
• Added proper subtitle support.
• Added proper support for matching episode names.
• Added support for full YYYY-MM-DD-type dates, usually useful for daily shows that otherwise have no episode name.
• Added support for 2020s release years.
• Added exceptions list for media with known, non-fixable issues.
• Expanded and improved matching for various fields.
• Fixed incorrect parsing of titles containing years.
• Fixed groups/encoders/websites mixups: a group/encoder is now just called an encoder, and a public tracker site goes under website.
• Added more tests and cleaned up previous ones.

/u/roidayan's work on top of the original

• Added support for complete season parsing (either just a full season, or a range), not just single episodes.
• Added to various fields' patterns.
• Improved season & episode matching.
• Fixed group names from having the container & bt site name.
• Added more tests.
