Editor

保留式原生代码编辑器，支持语法着色、行号、缩进和双轴滚动。

默认不包含任何语言语法。Rust 可注册静态链接的语法；Go 和 TypeScript 可通过 LoadLanguagePack / loadLanguagePack 加载单个跨平台包，其中包含所选 Tree-sitter Wasm 语法与查询。

组件默认不带视觉样式：文本和行号继承颜色，不添加背景、边框、圆角、内边距或语法／差异配色。外观由应用显式提供样式与颜色。

#导入

启用 QuickGUI 可选的 editor crate feature，并导入保留式编辑器类型。

use quickgui::{Editor, IntoElement, SyntaxLanguage, View, ViewContext};

#用法

struct EditorExample {
    editor: Editor,
}

impl View for EditorExample {
    fn render(&mut self, cx: &mut ViewContext<'_, Self>) -> impl IntoElement {
        let changed = cx.input_listener("source", |view, value, cx| {
            if view.editor.set_text(value).changed {
                cx.invalidate();
            }
        });
        self.editor.element("source").on_input(changed)
    }
}

#语法高亮

SyntaxLanguage 选择已注册的 Tree-sitter 语法和高亮查询。查询捕获结果会归并为八种稳定的 SyntaxTheme 类别，并以只影响前景色的 HighlightStyle 区间应用，因此颜色不会改变文本尺寸。源码或语言变化时重新解析受限文档；调色板变化只重新映射已有捕获，滚动不会执行语法分析。解析最多处理 2 MiB，超过 32 KiB 的单行保持普通颜色，捕获数量也有上限。这是结构化语法高亮，不是语言服务器语义标记。
