模块:Nav

简介

本模块为优化分析器展开模板过程中耗费的各项资源，仅针对{{Navbar}}、{{Navbox}}及其姊妹模板，作者为User:サンムル，部分模板在翻译改写过程中按照使用者习惯等因素对参数有部分增删。

外部调用

nav.bar

模块的导出函数之一，在Wiki代码中通过{{#invoke:Nav|bar}}调用，用于构建模板{{Navbar}}的Wiki代码。

nav.box

模块的导出函数之一，在Wiki代码中通过{{#invoke:Nav|box}}调用，用于构建模板{{Navbox}}及其姊妹模板的Wiki代码。

模块的第二个无名参数为Navbox的辅助模板{{Navbox subgroup}}、{{Navbox with columns}}和{{Navbox with collapsible groups}}样式启用进行填写，例如：{{#invoke:Nav|box|collapsible groups}}，目前Navbox subgroup已经使用本模块，建议不要另外调用。

--[[
    获取当前参数的序号，支持多个序号，且支持多种写法兼容。
pattern:
    格式以正则表达式为基础，另增以下匹配符：
    % - 将自动替换成正则表达式的“(%d+)”，用以匹配这个位置上的序号。
    %% - 将自动替换成正则表达式的“%”，用作正则表达式中“%”字符的转义。
返回：
    【所有序号文本】     【所有序号数值】
    注：以上每个值段都是一个独立的返回值列表项；
示例：
    paramname: prefix000infix10postfix08
    pattern: ^prefix%infix%postfix%$
    返回：000     10     08     0     10     8
