问题描述

将MarkDown转PDF

本文比较麻烦，还可以尝试 <a href="https://www.pandoc.org/">Pandoc</a>

<a href="https://download.csdn.net/download/lly1122334/12741869">本文全部代码及其CSS下载地址</a>

解决方案

使用 Typora 结合 <a href="https://wkhtmltopdf.org/downloads.html">wkhtmltopdf</a> 使用 markdown 库和 pdfkit 库

安装 mdutils

pip install markdown
pip install pdfkit

安装 wkhtmltopdf

<a href="https://wkhtmltopdf.org/downloads.html">wkhtmltopdf 下载地址</a>

添加到环境变量 Path 中（可使用绝对路径）在这里插入图片描述

代码

test.md 参考：

<a href="https://www.zybuluo.com/mdeditor">作业部落默认 Markdown 模板</a>

import pdfkit
from markdown import markdown

input_filename = 'test.md'
output_filename = 'test.pdf'

with open(input_filename, encoding='utf-8') as f:
   text = f.read()

html = markdown(text, output_format='html')  # MarkDown转HTML
pdfkit.from_string(html, output_filename, options={'encoding': 'utf-8'})  # HTML转PDF

# wkhtmltopdf = r'C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe'  # 指定wkhtmltopdf
# configuration = pdfkit.configuration(wkhtmltopdf=wkhtmltopdf)
# pdfkit.from_string(html, output_filename, configuration=configuration, options={'encoding': 'utf-8'})  # HTML转PDF

若没有配置环境变量，使用注释里的代码

效果

不支持标注不支持表格不支持LaTeX 不支持代码块不支持流程图、序列图、甘特图在这里插入图片描述

引入更多扩展

test.md

|项目|价格|数量|
|---|---|---|
|计算机|$1600|5|
|手机|$12|12|
|管线|$1|234|

无法正确渲染在这里插入图片描述

引入扩展 tables

import pdfkit
from markdown import markdown

text = '''|项目|价格|数量|
|---|---|---|
|计算机|$1600|5|
|手机|$12|12|
|管线|$1|234|'''
html = markdown(text, output_format='html', extensions=['tables'])  # MarkDown转HTML
pdfkit.from_string(html, 'test.pdf', options={'encoding': 'utf-8'})  # HTML转PDF

在这里插入图片描述

详细阅读：<a href="https://python-markdown.github.io/extensions/">Available Extensions</a>

引入数学包

HTML 引入 KaTeX markdown库启用mdx_math

安装

pip install python-markdown-math

import pdfkit
from markdown import markdown

input_filename = 'test.md'
output_filename = 'test.pdf'
html = '<!DOCTYPE html><body><script src="https://cdn.jsdelivr.net/npm/katex/dist/katex.min.js" crossorigin="anonymous"></script><script src="https://cdn.jsdelivr.net/npm/katex/dist/contrib/mathtex-script-type.min.js" defer></script>{}</body></html>'
text = '$$E=mc^2$$'
text = markdown(text, output_format='html', extensions=['mdx_math'])  # MarkDown转HTML
html = html.format(text)
pdfkit.from_string(html, output_filename, options={'encoding': 'utf-8'})  # HTML转PDF

详细阅读：<a href="https://github.com/Python-Markdown/markdown/wiki/Third-Party-Extensions">第三方扩展</a>

网页转PDF

生成HTML代码效果不完美，可以使用<a href="https://www.zybuluo.com/mdeditor#">作业部落</a>的导出HTML功能，再转PDF

import pdfkit

pdfkit.from_file('test.html', 'test.pdf', options={'encoding': 'utf-8'})  # HTML转PDF

封装

使用<a href="https://python-markdown.github.io/extensions/">官方扩展</a>和部分<a href="https://github.com/Python-Markdown/markdown/wiki/Third-Party-Extensions">第三方扩展</a>

安装库

pip install python-markdown-math
pip install pygments
pip install pymdown-extensions

下载CSS

<a href="https://github.com/sindresorhus/github-markdown-css">github-markdown.css</a> 改名为 markdown.css codehilite.css 生成命令 pygmentize -S default -f html -a .highlight > codehilite.css linenum.css

[data-linenos]:before {
  content: attr(data-linenos);
}

tasklist.css

.markdown-body .task-list-item {
  list-style-type: none !important;
}

.markdown-body .task-list-item input[type="checkbox"] {
  margin: 0 4px 0.25em -20px;
  vertical-align: middle;
}

代码

import os
import pdfkit
from markdown import markdown
from pymdownx import superfences


def markdown2pdf(input, output='test.pdf', encoding='utf-8', savehtml=False):
   html = '''
   <!DOCTYPE html>

if __name__ == '__main__':
   markdown2pdf('test.md', 'test.pdf', savehtml=True)
   print('完成')

效果看文末

PS：

缺什么找对应扩展即可，若无可自行编写。原理为MarkDown转HTML转PDF，pdfkit效果并不好，所以效果也有限。可使用 <a href="https://acrobat.adobe.com/cn/zh-Hans/free-trial-download.html">Adobe Acrobat Pro</a> 转换，但流程图等转换依旧不完美。

额外

这部分非通用MarkDown

代码行号

linenum.md

```python
if __name__ == '__main__':
   print('Hello World!')

import math

print(math.pi)  # 圆周率

 
 
linenum.css

[data-linenos]:before { content: attr(data-linenos); }

 
 
linenum.py

from markdown import markdown

filename = 'linenum.md' html = ''' <!DOCTYPE html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, minimal-ui"> <title>linenum</title>

</head> <body> <article class="markdown-body"> {} </article> </body> </html> ''' encoding = 'utf-8' with open(filename, encoding=encoding) as f: text = f.read()

extensions = [ 'pymdownx.superfences', # 多种块功能允许嵌套，各种图表 'pymdownx.highlight' # 高亮显示代码 ] extension_configs = { 'pymdownx.highlight': { 'linenums': True, # 显示行号 'linenums_style': 'pymdownx-inline' # 代码和行号分开 } } # 扩展配置 text = markdown(text, output_format='html', extensions=extensions, extension_configs=extension_configs) # MarkDown转HTML html = html.format(text) print(html) with open(filename.replace('.md', '.html'), 'w', encoding=encoding) as f: f.write(html)

pdfkit.from_string(html, output, options={'encoding': 'utf-8'}) # HTML转PDF

print('完成')

 
 
效果
![在这里插入图片描述](https://img-blog.csdnimg.cn/20200824140228516.png)
 这样直接复制代码不会带有行号
 
 
## 进度条

pdfkit.from_string(html, output, options={'encoding': 'utf-8'}) # HTML转PDF

print('完成')

 
 
progressbar.md
