# iced_custom_highlighter

[![builds.sr.ht status](https://builds.sr.ht/~pml68/iced_custom_highlighter.svg)](https://builds.sr.ht/~pml68/iced_custom_highlighter)

A custom syntax highlighter for iced.

It uses the colors from your app's Theme, based on a styling method (like `default_style`)

[`two-face`](https://github.com/CosmicHorrorDev/two-face) is used for providing extra syntaxes. [More info](https://github.com/CosmicHorrorDev/two-face?tab=readme-ov-file#syntaxes)

# Example

```rust
use iced::widget::{column, pick_list, text_editor};
use iced::{Element, Theme};
use iced_custom_highlighter::{Highlight, Highlighter, Settings};

#[derive(Default)]
struct State {
    content: text_editor::Content,
    theme: Option<Theme>,
}

#[derive(Debug, Clone)]
enum Message {
    Edit(text_editor::Action),
    ChangeTheme(Theme),
}

fn view(state: &State) -> Element<'_, Message> {
    column![
        text_editor(&state.content)
        .placeholder("Type something here...")
        .highlight_with::<Highlighter>(
            Settings::new(vec![], Highlight::default_style, "rs"),
            Highlight::to_format,
        )
        .on_action(Message::Edit),
        pick_list(
            state.theme.clone(),
            Theme::ALL,
            Theme::to_string
        )
        .on_select(Message::ChangeTheme),
    ].into()
}

fn update(state: &mut State, message: Message) {
    match message {
        Message::Edit(action) => {
            state.content.perform(action);
        }

        Message::ChangeTheme(theme) => {
            state.theme = Some(theme);
        }
    }
}
