附： md 批量转换到 pdf 文件
a) 需安装 pandoc， 拷贝 template.tex 到 /usr/share/pandoc/data/templates/ 目录中。
b) 需安装中文字体。
c) 需安装 xelatex.
d) 代码 md2pdfs.py 及模板 template.tex 如下：
from pathlib import Path
import os
def md2pdfs(currdir='.'):
dir = os.path.abspath(currdir)
files = os.listdir(dir)
for f in files:
path = os.path.join(dir, f)
if os.path.isdir(path):
md2pdfs(path)
dir = os.path.dirname(path)
continue
name = os.path.splitext(f)[0]
ext = os.path.splitext(f)[1]
if ext == '.md':
mdfile = f
pdffile = name + '.pdf'
os.chdir(dir)
print(os.getcwd() + '/' + f)
cmd = "pandoc '{0}' -o '{1}' --latex-engine=xelatex -V mainfont='PingFang SC' --template=template.tex".format(mdfile, pdffile)
os.system(cmd)
