[英]How to modify an inline element in Pandoc using lua filter?
I am beginner in Pandoc and Lua who is experimenting with converting Word documents to Markdown. I want to convert chapter headings in Word to paragraph of text in Markdown. Furthermore, I want to insert some text before and after the chapter headings.我是 Pandoc 和 Lua 的初学者,正在尝试将 Word 文档转换为 Markdown。我想将 Word 中的章节标题转换为 Markdown 中的文本段落。此外,我想在章节标题前后插入一些文本。
To achieve that, I used the following lua filter (sample.lua)为此,我使用了以下 lua 过滤器 (sample.lua)
function Header(el)
if el.level == 1 then
return {"something before (",el.content,") something after"}
end
end
after which I performed the conversion using之后我使用
pandoc --lua-filter=sample.lua -s file.docx -t markdown -o file.txt
pandoc --lua-filter=sample.lua -s file.docx -t markdown -o file.txt
where file.docx is just minimal example document containing one chapter heading.其中 file.docx 只是包含一个章节标题的最小示例文档。 However, using this filter, I obtained
但是,使用这个过滤器,我得到了
something before (
Chapter title
) something after
What I want to get, however, is然而,我想要得到的是
something before (Chapter title) something after
but since (if I am not mistaken) el.content is inline element, there are linebreaks around it.但是因为(如果我没记错的话)el.content 是内联元素,所以它周围有换行符。 I tried to solve this problem by using pandoc documentation and various lua functions, but to no avail, which is why I would kindly ask for help.
我试图通过使用 pandoc 文档和各种 lua 函数来解决这个问题,但无济于事,这就是为什么我会请求帮助。
Try this instead:试试这个:
function Header(el)
if el.level == 1 then
return {{"something before ("} .. el.content .. {") something after"}}
end
end
The reason is that el.content
is a list of inline elements, and it can be be extended by concatenating lists with additional content.原因是
el.content
是一个内联元素列表,可以通过将列表与附加内容连接起来进行扩展。 The operator ..
is the concatenation operator;运算符
..
是串联运算符; it works with strings and pandoc lists.它适用于字符串和 pandoc 列表。
