模块:效果说明高亮

此模块的文档可以在模块:效果说明高亮/doc创建

-- Module:KeywordTooltip
local p = {}

-- 1. 模块加载时只解析一次关键词
local txt = mw.title.new('模板:效果说明'):getContent() or ''
local descDict = {}
for key, desc in string.gmatch(txt, '|%s*([^=|]+)%s*=%s*([^\n]+)') do
    key = mw.text.trim(key)
    desc = mw.text.trim(desc)
    if key ~= '' and desc ~= '' then
        descDict[key] = desc
    end
end

-- 2. 关键词按长度排序
local sorted = {}
for k in pairs(descDict) do table.insert(sorted, k) end
table.sort(sorted, function(a, b) return #a > #b end)

-- 3. esc函数
local function esc(s)
    return s:gsub('[%(%)%.%%%+%-%*%?%[%]%^%$]', '%%%1')
end

-- 4. 带内存保护的缓存
local cache = {}
local cacheSize = 0
local MAX_CACHE_SIZE = 5000 -- 最多缓存5000个技能描述

function p.annotate(frame)
    local text = frame.args[1] or ''

    if cache[cacheKey] then
        return cache[cacheKey]
    end
    
    -- 扫描所有关键词位置
    local marks = {}
    for _, k in ipairs(sorted) do
        local pat = esc(k)
        local startPos = 1
        while true do
            local pos = text:find(pat, startPos, true)
            if not pos then break end

                end
            end
            
            if not conflict then

                })
            end
            startPos = pos + 1
        end
    end
    
    -- 倒序替换为HTML
    table.sort(marks, function(a, b) return a.start > b.start end)

            mw.text.nowiki(m.desc),
            m.keyword
        ) .. after
    end
    
    -- 缓存并控制大小
    if cacheSize < MAX_CACHE_SIZE then
        cache[cacheKey] = result
        cacheSize = cacheSize + 1
