##### Flags
- `--audio` » forces audio of the video(s)
- `--subtitle` » forces subtitle of the video(s)

- `--only-sub` » downloads only the subtitles without the corresponding video
- `-d`, `--directory` » directory to download the video(s) to
- `-o`, `--output` » name of the output file
The following flags can be (optional) passed to modify the [download](#download) process.
- `-r`, `--resolution` » the resolution of the video(s). `best` for best resolution, `worst` for worst
| Short | Extended | Description |
|-------|----------------|--------------------------------------------------------------------------------|
| `-a` | `--audio` | Forces audio of the video(s). |

### Archive

Archive works just like [download](#download). It downloads the given videos as `.mkv` files and stores all (soft) subtitles in it.
Default audio locales are japanese and your system language (if available) but you can set more or less with the `--language` flag.

## 📚 Library
Download the library via `go get`
```
```shell
$ go get github.com/ByteDream/crunchyroll-go
```
### 📝 Examples
```go
func main() {
// login with credentials
crunchy, err := crunchyroll.LoginWithCredentials("user@example.com", "password", crunchyroll.US, http.DefaultClient)
if err != nil {
panic(err)
}
The documentation is available on [pkg.go.dev](https://pkg.go.dev/github.com/ByteDream/crunchyroll-go).
// finds a series or movie by a crunchyroll link
video, err := crunchy.FindVideo("https://www.crunchyroll.com/darling-in-the-franxx")
if err != nil {
panic(err)
}
Examples how to use the library and some features of it are described in the [wiki](https://github.com/ByteDream/crunchyroll-go/wiki/Library).
series := video.(*crunchyroll.Series)
seasons, err := series.Seasons()
if err != nil {
panic(err)
}
fmt.Printf("Found %d seasons for series %s\n", len(seasons), series.Title)
# ☝️ Disclaimer
// search `Darling` and return 20 results
series, movies, err := crunchy.Search("Darling", 20)
if err != nil {
panic(err)
}
fmt.Printf("Found %d series and %d movies for query `Darling`\n", len(series), len(movies))
}
```
This tool is **ONLY** meant to be used for private purposes.
To use this tool you need crunchyroll premium anyway, so there is no reason why rip and share the episodes.
```go
func main() {
crunchy, err := crunchyroll.LoginWithSessionID("8e9gs135defhga790dvrf2i0eris8gts", crunchyroll.US, http.DefaultClient)
if err != nil {
panic(err)
}
// returns an episode slice with all episodes which are matching the given url.
// the episodes in the returning slice differs from the underlying streams, but are all pointing to the first ditf episode
episodes, err := crunchy.FindEpisode("https://www.crunchyroll.com/darling-in-the-franxx/episode-1-alone-and-lonesome-759575")
if err != nil {
panic(err)
}
fmt.Printf("Found %d episodes\n", len(episodes))
}
```
<h4 align="center">Structure</h4>
Because of the apis structure, it can lead very fast much redundant code for simple tasks, like getting all episodes
with japanese audio and german subtitle. For this case and some other, the api has a utility called `Structure` in its utils.
```go
func main() {
crunchy, err := crunchyroll.LoginWithCredentials("user@example.com", "password", crunchyroll.US, http.DefaultClient)
if err != nil {
panic(err)
}
// search `Darling` and return 20 results (series and movies) or less
series, movies, err := crunchy.Search("Darling", 20)
if err != nil {
panic(err)
}
fmt.Printf("Found %d series and %d movies for search query `Darling`\n", len(series), len(movies))
seasons, err := series[0].Seasons()
if err != nil {
panic(err)
}
// in the crunchyroll.utils package, you find some structs which can be used to simplify tasks.
// you can recursively search all underlying content
seriesStructure := utils.NewSeasonStructure(seasons)
// this returns every format of all the above given seasons
formats, err := seriesStructure.Formats()
if err != nil {
panic(err)
}
fmt.Printf("Found %d formats\n", len(formats))
filteredFormats, err := seriesStructure.FilterFormatsByLocales(crunchyroll.JP, crunchyroll.DE, true)
if err != nil {
panic(err)
}
fmt.Printf("Found %d formats with japanese audio and hardsubbed german subtitles\n", len(filteredFormats))
// reverse sorts the formats after their resolution by calling a sort type which is also defined in the api utils
// and stores the format with the highest resolution in a variable
sort.Sort(sort.Reverse(utils.FormatsByResolution(filteredFormats)))
format := formats[0]
// get the episode from which the format is a child
episode, err := seriesStructure.FilterEpisodeByFormat(format)
if err != nil {
panic(err)
}
file, err := os.Create(fmt.Sprintf("%s.ts", episode.Title))
if err != nil {
panic(err)
}
// download the format to the file
if err := format.DownloadGoroutines(file, 4, nil); err != nil {
panic(err)
}
fmt.Printf("Downloaded %s with %s resolution and %.2f fps as %s\n", episode.Title, format.Video.Resolution, format.Video.FPS, file.Name())
// for more useful structure function just let your IDE's autocomplete make its thing
}
```
As you can see in the example above, most of the `crunchyroll.utils` Structure functions are returning errors. There is
a build-in functionality with are avoiding causing the most errors and let you safely ignore them as well.
**Note that errors still can appear**
```go
func main() {
crunchy, err := crunchyroll.LoginWithCredentials("user@example.com", "password", crunchyroll.US, http.DefaultClient)
if err != nil {
panic(err)
}
foundEpisodes, err := crunchy.FindEpisode("https://www.crunchyroll.com/darling-in-the-franxx/episode-1-alone-and-lonesome-759575")
if err != nil {
panic(err)
}
episodeStructure := utils.NewEpisodeStructure(foundEpisodes)
// this function recursively calls all api endpoints, receives everything and stores it in memory,
// so that after executing this, no more request to the crunchyroll server has to be made.
// note that it could cause much network load while running this method.
//
// you should check the InitAllState before, because InitAll could have been already called or
// another function has the initialization as side effect and re-initializing everything
// will change every pointer in the struct which can cause massive problems afterwards.
if !episodeStructure.InitAllState() {
if err := episodeStructure.InitAll(); err != nil {
panic(err)
}
}
formats, _ := episodeStructure.Formats()
streams, _ := episodeStructure.Streams()
episodes, _ := episodeStructure.Episodes()
fmt.Printf("Initialized %d formats, %d streams and %d episodes\n", len(formats), len(streams), len(episodes))
}
```
### Tests
You can also run test to see if the api works correctly.
Before doing this, make sure to either set your crunchyroll email and password or sessions as environment variable.
The email variable has to be named `EMAIL` and the password variable `PASSWORD`. If you want to use your session id, the variable must be named `SESSION_ID`.
You can run the test via `make`
```
$ make test
```
or via `go` directly
```
$ go test .
```

# 🗒️ Notice
Sometimes the download stops without a reason on linux and does not go further. In this case the `tmpfs` / `/tmp` directory may be full. Execute `df /tmp` to see how much of the space is used.
I would really appreciate if someone rewrites the complete cli. I'm not satisfied with it's current structure but at the moment I have no time and no desire to do it myself.
**The responsibility for what happens to the downloaded videos lies entirely with the user who downloaded them.**
