Copy the link and turn the HTML of the body into markdown

As I am very inefficient, sometimes it is inevitable to be urged more ha

As we all know, laziness is the motivation for people to innovate

So I wrote a copy of the crawler script, I see feel good articles, directly climb over, and then use the wechat public number format to share with you ~

(Mainly because some articles are rich in gold, but ugly, just like you and me)

Of course, THE shared content I will not mark the original, as my personal favorites, will also indicate the link to reprint

role

Convert regular blogs, through crawlers and character processing, tomarkdownFormatted text

There are similar tools online, including the more famous python third-party libraries html2text, also have some problems more or less, try once, http://www.atoolbox.net/Tool.php?Id=715 is the most accurate

So I wrote one myself

usage

python3 blog2md.py
Copy the code

After entering the link that you want to copy and collect

The terminal will then output the converted result in MD format, and in the same directory, blog.md will be generated

demo

Crawl content is from my last original article: [

Python crawler – automatically gets the title of the reference link – into markdown format](blog.csdn.net/Mxdon_on/ar…)

Console output

As you can see, we have almost all the formatting we need

The file preview

[@path/to/blog2md.py] $ ls
blog2md.py  blog.md
Copy the code

At this point, the blog.md file has been generated in the same directory. Let’s open it for a preview and see what it looks like

It’s exactly the same as the original I wrote myself

Completed function

Solve bold, strikeout, italics and other textmarkdownstyle
Solve images and linksmarkdownAccording to
Solve the multi-level title and page title selection, as well as directorytocjoin
Resolve conflicts between in-line code and block code display embedded in articles, supporting in-block code in different languages
Support zhihu articles,csdnArticles, short books and blog garden articles, others have not yet been tested
Supports the command line interaction mode

TODO

Multi-level references are not yet tested by differentmarkdownThe rendering tool decided that there would be a problem
In-block code can be a bit of a problem in some outrageous formats, but it doesn’t affect usage for now
Formula not supported
It’s not packaged graphically
Multi-level lists are also a bit problematic
Some pictures of the website do not support reference, such as some pictures of CSDN, which may need to be decoded first
Should be the final generated document, according to the title of the name to regenerate the file, ah a line of code, do not want to do, enough for my own use
Something magicalAn empty divLabel is outrageous, a label nearly 100 lines, and then it will be a bit of a problem, fortunately, not much, directly delete it first
Tables not supported
There’s a little bit of space at the beginning, not yet

Markdown is still rendered as HTML

code

I thought it might be useful, so I threw it in Gitee. If you need it, you can change it and use it together
