模組:Hatnote list

模块文档[查看] [编辑] [历史] [清除缓存]

從維基文本中的使用

雖然forSee接受一個初始的frame參數，並且可能可以從維基文本中使用，但這個模塊並不是直接設計用於維基文本的，例如：

• {{hatnote|PREFIX {{#invoke:Hatnote list|forSee|{{tl|For}}|Module:For|{{tl|About}}|Module:About}} POSTFIX}} →
  PREFIX 关于{{For}}，请见「Module:For」。关于{{About}}，请见「Module:About」。 POSTFIX

從 Lua 中的使用

要調用該模塊，請使用

local mHatList = require('Module:Hatnote list')

或類似的方式，然後通過 mHatList 變量（或其他使用的變量）訪問其方法。

andList（和列表）

andList 接受一個表格形式的列表，返回一個字符串，其中列表以「和」以及適當的逗號分隔。

orList（或列表）

orList 接受一個表格形式的列表，返回一個字符串，其中列表以「或」以及適當的逗號分隔。

forSee（參見）

_forSee 接受三個參數：一個修剪過且去除空白的參數表，一個從哪個索引開始的「from」數字，以及一個選項表，並返回一個字符串，其中包含一系列 "For X, see [[Y]]" 句子。鏈接使用 Module:Hatnote 中的方法格式化。

為方便起見，forSee 方法（去掉前面的底線）接受相同的參數，除了使用框架而不是參數表，使用 Module:Arguments 中的 getArgs() 預處理參數。

-- This module produces and formats lists for use in hatnotes. In particular, --
-- it implements the for-see list, i.e. lists of "For X, see Y" statements,   --
-- as used in {{about}}, {{redirect}}, and their variants. Also introduced    --
-- are andList & orList helpers for formatting lists with those conjunctions. --
