这是模板链接：{{NavboxV2}}的Lua实现代码。

简介

合并了模板链接：{{Navbox}}相关的一系列模板。融合了模板链接：{{Navbox}}的行式、模板链接：{{Navbox subgroup}}的子代模块包含、模板链接：{{Navbox with columns}}的列式，模板链接：{{Navbox with collapsible groups}}）的折叠行式。

改写自模块:Navbox。

设计用途

在Category:引用模板后大小超过限制的页面中，有相当一部分页面是由于模板链接：{{Navbox}}模板超载导致。

  • 根据QW:模板限制中“嵌套展开”的说法，相同页面的多次嵌套调用是会被分次统计的（例如：页面A嵌入页面B，页面B嵌入页面C，页面C相对页面A统计到的展开字节数是被计算了2次）。而现在Navbox的子代块、列式，折叠行式的实现都是基于Navbox行式的模板调用或类似样式结构迭代，这样就符合内部多次调用Navbox的条件，页面很容易会超过模版展开后大小的限制。
  • 其次，实际上Lua的运行限制条件相当宽裕，50MB的内存限制，10秒的运行时限制，很多页面实际使用只在十分之一左右或以下，可以被大量压榨性能。

所以将Navbox所有的实现全部以Lua实现，希望能腾出解释器运行量到Lua运行量，降低解析器触发展开后大小限制的可能。

效果

在对于包含一层子Navbox的情况，展开后大小下降最多有50~60%左右。

参数

与模板链接：{{Navbox}}系列模板几乎兼容。但新增部分参数填入：

  • type：Navbox的类型，对应值为vertical（对应模板链接：{{Navbox}}）、horizontal（对应模板链接：{{Navbox with columns}}）、vertical_collapsible（对应模板链接：{{Navbox with collapsible groups}}），默认值为vertical。
  • border：Navbox的隐藏参数，用于控制Navbox的边框机制来使子Navbox能被嵌入到父Navbox的值字段（例如list、col等）中，实际对应模板链接：{{Navbox subgroup}}的实现机制。对应值为child、subgroup任一个。
在本模板添加子Navbox层时，必须传入这两个参数，这是本模板区分是否存在子Navbox层的依赖。本模板首层Navbox层无需添加border，按需添加type。
  • removeGroupPadding：用于区别模板链接：{{Navbox|child}}和模板链接：{{Navbox subgroup}}，后者在Groupn字段的单元格增加一组padding的配置，适用于子Navbox层。任意值，存在则可，为移除该padding配置（对应模板链接：{{Navbox|child}}）。

自模板链接：{{Navbox}}系列模板转换

将原有嵌入模板链接：{{Navbox}}系列模板的值字段listn（其他类同）改为listn-，并作为相应嵌套子Navbox模板的参数的前缀来加入，使这些模板嵌套转换为扁平化的一层模板参数。

例子
模板链接：{{Navbox}}系列 本模板 
{{Navbox
|name = Navbox/doc
|state = uncollapsed
|image = {{{image}}}
|imageleft = {{{imageleft}}}
|title = {{{title}}}
|above = {{{above}}}
|group1 = {{{group1}}}
|list1 = {{Navbox subgroup
 | title = {{{list1-title}}}
 | above = {{{list1-above}}}
 | below = {{{list1-below}}}
 | imageleft = {{{list1-imageleft}}}
 | image = {{{list1-image}}}
 | group1 = {{{list1-group1}}}
 | list1  = {{{list1-list1}}}
 | group2 = {{{list1-group2}}}
 | list2  = {{{list1-list2}}}
}}
|group2 = {{{group2}}}
|list2 = {{Navbox subgroup
| group1 = {{{list2-group1}}}
| list1  = {{{list2-list1}}}
| group2 = {{{list2-group2}}}
| list2  = {{{list2-list2}}}
}}
|below = {{{below}}}
}}

{{NavboxV2
|name = Navbox/doc
|state = uncollapsed
|image = {{{image}}}
|imageleft = {{{imageleft}}}
|title = {{{title}}}
|above = {{{above}}}
<!--  list1 -->
|group1 = {{{group1}}}
<!-- list1-sub-->
|list1-type =vertical <!--作为list1的子Navbox层，全部相应参数加上对应前缀“list1-”，下同，如此类推 -->
|list1-border=child
|list1-title = {{{list1-title}}}
|list1-above = {{{list1-above}}}
|list1-below = {{{list1-below}}}
|list1-imageleft = {{{list1-imageleft}}}
|list1-image = {{{list1-image}}}
|list1-group1 = {{{list1-group1}}}
|list1-list1  = {{{list1-list1}}}
|list1-group2 = {{{list1-group2}}}
|list1-list2  = {{{list1-list2}}}
<!--  list2 -->
|group2 = {{{group2}}}
<!-- list2-sub-->
|list2-type =vertical <!--作为list2的子Navbox层，全部相应参数加上对应前缀“list2-”，下同，如此类推 -->
|list2-border=child
|list2-group1 = {{{list2-group1}}}
|list2-list1  = {{{list2-list1}}}
|list2-group2 = {{{list2-group2}}}
|list2-list2  = {{{list2-list2}}}
<!--end-->
|below = {{{below}}}
}}

转换注意

由于模板链接：{{Navbox}}系列的实现较为复杂和涉及自我嵌套，本模板的实现也为此做了对应兼容性调整，可能会出现一些参数被过度透传（可能在样式控制部分，原因是原有设计通过控制参数传入来隔离，而本设计为了使参数扁平化，导致部分这些参数无法隔离）。而且模板参数非常依赖命名规律，在转换替换前，请进行testcase检查，确认转换后能与原来的样式、功能基本一致，才应用转换。如果出现问题，请保留案例并联系本模板维护编辑协助处理，或者放弃。

虽然可以在值字段（例如list、col等）重新嵌入模板链接：{{Navbox}}系列模板，但这和原有做法一样，失去了本模板降低解析器限制的作用，不建议这样做。
