ExportUtil 导出模块

本模块负责将比赛成绩导出为 HTML 或 CSV 格式。

HTML 导出采用 JSON + 模板 方案：C++ 端通过 buildExportJson() 构建包含全部比赛数据的 JSON 对象，然后将其嵌入 export_template.html 中的 %%DATA%% 占位符，由浏览器端 JavaScript 完成页面渲染。这种方式将数据构造与页面展示解耦，C++ 代码只需关注 JSON 结构，无需拼接 HTML 字符串。

以下是 JSON 数据的结构说明。

顶级字段

字段名 类型 说明 举例
name string 比赛名称 "contest"
version string LemonLime 版本 "Lemonlime Version 0.3.6.1:7545e02"
task_names string[] 题目名称数组 ["plus", "minus"]
i18n object i18n 字典 见下节
contestants object[] 选手成绩数据数组 见下节

i18n

字段名 举例
rank_list "排名表"
hint "点击名字或单题分数跳转到详细信息。使用 LemonLime 评测"
rank "排名"
name "名称"
total "总分"
contestant "选手"
task "试题"
source_file "源程序："
no_source "未找到选手程序"
testcase "测试点"
input "输入文件"
result "测试结果"
time "运行用时"
memory "内存消耗"
score "得分"
return_to_top "返回顶部"

contestants 数组内对象

字段名 类型 说明 举例
name string 选手姓名 "Alice"
rank number 选手排名 1
total_score number 选手总分 200
total_bg string 总分单元格背景 (HSL) "0, 70%, 90%"
total_border string 总分单元格边框 (HSL) "0, 70%, 50%"
tasks object[] 题目结果数组 见下节

tasks 数组内对象

字段名 类型 说明 举例
score number 该题单项得分 100
bg string 该题得分背景 (HSL) "120, 30%, 60%"
file string 选手程序文件名（可选，若无该字段则表示找不到选手程序） "plus.cpp"
details object[] 测试点详情数组 见下节

details 数组内对象

字段名 类型 说明 举例
label string 测试点编号或子任务信息，允许使用 <br> "#2<br/>子任务依赖情况:Pure"
row_span number 合并单元格行数（0 表示该行被合并，1 表示该行不合并） 1
input string 该测试点输入文件名 "plus2.in"
result string 评测状态结果文字 "评测通过"
time string 运行耗时字符串 "0.005 s"
memory string 内存占用字符串 "5.34 MB"
score number 该项得分 20
full_score number 该项满分 20
bg string 状态背景 (RGB) "rgb(192, 255, 192)"
info string 测评信息（可选） 在第四行，读取到 123456，但期望 789123
