TVrank: A Rust library and command-line utility for ranking movies and series

Github Repository

tvrank is a library and command-line utility written in Rust for querying and ranking information about movies and series. It can be used to query a single title or scan directories.

Currently, tvrank only supports IMDB's TSV dumps which it automatically downloads, caches and periodically updates. More work is required to be able to support and cache live-query services like TMDB.

Additionally, the "in-memory database" could use improvements through indexing and through adding support for a persistent cache. Also, the library's documentation is missing but there is an example on how to use it.

For now, the command-line utility of tvrank works well and fast enough to be usable.

Note that tvrank depends on the flate2 crate for decompression of IMDB TSV dumps. flate2 is extremely slow when built in debug mode, so it is recommended to always run tvrank in release mode unless there are good reasons not to. By default, release mode is built with debugging information enabled for convenience during development.

Usage

For information on how to use the library, see below.

The tvrank command-line interface has a few modes enabled by the use of sub-commands: title "TITLE (YYYY)" to search for titles (by title and year), title "keyword1 keyword2 ..." to search titles based on keywords, movies-dir and series-dir to make batch queries based on directory scans.

To query a single title:

sh tvrank title "the great gatsby (2013)"

To query based on keywords:

sh tvrank title "the great gatsby"

To query a series directory:

sh tvrank series-dir <MEDIA_DIR>

Also, by default tvrank will sort by rating, year and title. To instead sort by year, rating and title, --sort-by-year can be passed before any sub-command:

sh tvrank --sort-by-year title "house of cards"

To print out more information about what the application is doing, use -v before any sub-command. Multiple occurrences of -v on the command-line will increase the verbosity level:

sh tvrank -vvv --sort-by-year title "city of god"

To find help, see the help sub-command:

sh tvrank help tvrank help title tvrank help series-dir tvrank help movies-dir

Screencast

Please note that the screencast is slightly outdated. Please use the movies-dir or series-dir sub-commands instead of -d as used in the screencast.

Using the library

Add the dependency to your Cargo.toml:

toml [dependencies] tvrank = "0.4"

Or, using cargo add:

sh $ cargo add tvrank

Include the Imdb type:

rust use tvrank::imdb::{Imdb, ImdbQueryType};

Create a directory for the cache using the tempfile crate then create the database service. The closure passed to the service constructor is a callback for progress updates and is a FnMut to be able to e.g. mutate a progress bar object.

rust let cache_dir = tempfile::Builder::new().prefix("tvrank_").tempdir()?; let imdb = Imdb::new(cache_dir.path(), false, &mut |_| {})?;

Afterwards, one can query the database using either imdb.by_id(...), imdb.by_title(...), imdb.by_title_and_year(...) or imdb.by_keywords(...), and print out some information about the results.

```rust let title = "city of god"; let year = 2002;

println!("Matches for {} and {:?}:", title, year);

for title in imdb.bytitleandyear(title, year, ImdbQueryType::Movies)? { let id = title.titleid();

println!("ID: {}", id); println!("Primary name: {}", title.primarytitle()); if let Some(originaltitle) = title.originaltitle() { println!("Original name: {}", originaltitle); } else { println!("Original name: N/A"); }

if let Some((rating, votes)) = title.rating() { println!("Rating: {}/100 ({} votes)", rating, votes); } else { println!("Rating: N/A"); }

if let Some(runtime) = title.runtime() { println!("Runtime: {}", humantime::format_duration(runtime)); } else { println!("Runtime: N/A"); }

println!("Genres: {}", title.genres()); println!("--"); } ```

See the query example under the examples/ directory for a fully-functioning version of the above.
