模块:Utils

可在模块:Utils/doc创建此模块的帮助文档

local p = {}

-- 辅助函数：去除字符串尾部的所有空白字符（空格、换行、回车等）
local function trimTrailing(str)
    if str then
        return str:gsub("%s+$", "")
    end
    return str
end

-- 条件函数，用法：{{#invoke:utils|ifeq|条件|为真输出|为假输出}}
function p.ifeq(frame)
    local cond = frame.args[1] or ''
    if cond ~= '' then
        return frame.args[2]
    else
        return frame.args[3]
    end
end
-- 一个用来打表的函数，会自动适配内容数量，用法：{{#invoke:utils|row|目标1|注释1|...}}
function p.row(frame)
    local args = frame.args
    local cells = {}

    local i = 1
    while true do
        local val1 = args[i]
        if val1 == nil then break end
        val1 = trimTrailing(val1)
        i = i + 1
        local val2 = args[i]
        if val2 == nil then break end
        val2 = trimTrailing(val2)
        table.insert(cells,val1.." || "..val2)
        i = i + 1
    end
    if #cells == 0 then return "no arg" end
    return "|-\n| " .. table.concat(cells, "\n|-\n| ")
end

-- 打表专用的配套函数
function p.showIf(frame)
    local cond = frame.args['cond'] or ''
    local thenText = frame.args['then'] or ''
    local elseText = frame.args['else'] or ''

    if cond ~= '' then
        return thenText
    else
        return elseText
    end
end

return p
