QuickGUI

CodeBlock

可选择、无插入光标的代码视图，支持 Tree-sitter 着色和逻辑行虚拟化。

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

go get github.com/egoist/quickgui/extensions/editor
import (
	"github.com/egoist/quickgui/extensions/editor"
	"github.com/egoist/quickgui/go/ui"
)

#用法

func CodeExample() *ui.Element {
	return editor.CodeBlock(editor.CodeBlockProps{
		Value:       "package main\n\nfunc main() {}\n",
		Language:    "go",
		LineNumbers: true,
		Wrap:        false,
		Props:       ui.Props{Style: ui.Style().Width("100%").Height(280)},
	})
}

#语法高亮

Language 选择已注册的 Tree-sitter 语法和高亮查询。捕获结果通过 SyntaxTheme 映射为只影响前景色的区间，因此高亮不会改变布局。源码或语言变化时由 Rust 核心解析；滚动只挂载逻辑行并创建预先计算的区间。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。
