## Subtitles

```elixir
alias GoSaveTool.Subtitles

vtt = Subtitles.convert(File.read!("movie.srt"), :vtt)
cues = Subtitles.parse(text)                     # [%Cue{start: 1000, stop: 3500, settings: "", text: "Hello"}, ...]
later = cues |> Subtitles.shift(1500) |> Subtitles.to_srt()
{fixed, n} = Subtitles.repair(cues)              # sorted, no overlaps, no empty cues
```

## Text

```elixir
alias GoSaveTool.Text

Text.stats(post)                                 # %{words: 42, chars: 230, chars_no_spaces: 190, lines: 3, sentences: 4, read_seconds: 11}
Text.check_limits(post)["x-post"].fits           # also instagram-caption, tiktok-caption, youtube-title, seo-title, ...
Text.title("the lord of the rings")              # "The Lord of the Rings"
Text.slug("Ölçü Birimi & Çeviri!")               # "olcu-birimi-ceviri"
Text.camel("best posting time")                  # "bestPostingTime"
```

Characters are Unicode code points, so an emoji counts as one, as on social media. The rules are the same as the [`@gosavetool/subtitles`](https://www.npmjs.com/package/@gosavetool/subtitles) and [`@gosavetool/text`](https://www.npmjs.com/package/@gosavetool/text) JavaScript packages.

## Tests
