hypher

hypher separates words into syllables.

toml [dependencies] hypher = "0.1"

Features

• All-inclusive: Hyphenation patterns are embedded into the binary as efficiently encoded finite automata at build time.
• Zero load time: Hyphenation automata operate directly over the embedded binary data with no up-front decoding.
• No allocations unless when hyphenating very long words (>= 39 bytes). You can disable the alloc feature, but then overly long words lead to a panic.
• Support for many languages.
• No unsafe code, no dependencies, no std.

Example

```rust use hypher::{hyphenate, Lang};

let syllables = hyphenate("extensive", Lang::English); assert_eq!(syllables.join("-"), "ex-ten-sive"); ```

Languages

By default, this crate supports hyphenating more than 30 languages. Embedding automata for all these languages will add ~1.1 MiB to your binary. Alternatively, you can disable support for all languages and manually choose which ones get added:

toml [dependencies] hypher = { version = "0.1", default-features = false, features = ["english", "greek"] }

Each language added individually contributes:

| Language | Space | |------------|---------| | Afrikaans | 60 KiB | | Belarusian | 3.9 KiB | | Bulgarian | 13 KiB | | Danish | 5.7 KiB | | German | 192 KiB | | Greek | 2.0 KiB | | English | 27 KiB | | Spanish | 14 KiB | | Estonian | 19 KiB | | Finnish | 1.3 KiB | | French | 6.9 KiB | | Croatian | 2.0 KiB | | Hungarian | 346 KiB | | Icelandic | 21 KiB | | Italian | 1.6 KiB | | Georgian | 11 KiB | | Kurmanji | 1.4 KiB | | Latin | 1003 B | | Lithuanian | 6.5 KiB | | Mongolian | 4.9 KiB | | Dutch | 63 KiB | | Norwegian | 153 KiB | | Portuguese | 343 B | | Russian | 33 KiB | | Serbian | 13 KiB | | Slovak | 13 KiB | | Slovenian | 5.5 KiB | | Albanian | 1.4 KiB | | Swedish | 24 KiB | | Turkmen | 1.4 KiB | | Turkish | 526 B | | Ukrainian | 21 KiB |
