unicode-linebreak

Implementation of the Line Breaking Algorithm described in Unicode Standard Annex #14.

Given an input text, locates "line break opportunities", or positions appropriate for wrapping lines when displaying text.

Example

```rust use unicode_linebreak::{linebreaks, BreakOpportunity::{Mandatory, Allowed}};

let text = "a b \nc"; assert!(linebreaks(text).eq([ (2, Allowed), // May break after first space (5, Mandatory), // Must break after line feed (6, Mandatory) // Must break at end of text, so that there always is at least one LB ])); ```

Development

After cloning the repository or modifying LineBreak.txt the tables have to be (re-)generated:

```sh

Generate src/tables.rs

(cd gen-tables && cargo run)

Run tests to make sure it was successful

cargo test ```
