lua-widow-control：是否可以将警告更改为信息

我正在使用 nice 包lua-widow-control来稍微改善文档的外观。但是，警告消息“未在页面 ... 上删除寡妇/孤儿/损坏的连字符”太长（包含太多行），并且当文档变得冗长时，大量此类警告消息有时会淹没其他重要警告。我想知道在文档未完成时是否有某种方法可以将这些消息从“警告”级别更改为“信息”？

下面是此类警告消息的一个示例。

Widow/Orphan/Broken Hyphen NOT removed on page 10
[10] [11]
warning  (pdf backend): ignoring duplicate destination with the name 'page.11'
[11] (./the-document.aux))

--- When we are unable to remove a widow/orphan, print a warning
---
--- @return nil
local function remove_widows_fail()
    warning("Widow/Orphan/Broken Hyphen NOT removed on page " .. pagenum)

在texmf-dist/tex/luatex/lua-widow-control/lua-widow-control.lua

因此，它是声明内部的本地定义函数调用 ( warning) local。因此，根据设计，您无法从外部对其进行修补。

但是，您可以将该文件复制到当前目录（或路径中的任何位置），然后在第 242 行左右看到

        warning = function(str) luatexbase.module_warning(lwc.name, str) end
        info = function(str) luatexbase.module_info(lwc.name, str) end

如果你改为，_warning那么_info就会warning()像info()只写入日志
