我能够做到。我对自己的解决方案并不完全满意，但这已经足够了。等待其他人提供更好的解决方案。
该过程如下。将markdown转换为html并将其附加到邮件。将此附件转为inline附件。但是现在我有两个附件，第一个是markdown，第二个是html。将markdown内容替换为空字符串，以便仅发送html。
我在~/.muttrc文件中添加了以下行。
macro compose B ":set editor=text2mime-markdown.py<enter>E:set editor=email-editor<enter>Da/tmp/html-markdown-alternative.html<enter>^Du"
这是email-editor从有问题的链接中借来的。
#!/bin/sh
if grep -q In-Reply-To $1; then
# Jump to first line of message
exec vim -c 'norm }j' $1
else
# Enter insert mode on the To: line
exec vim $1
fi
然后是主要的python文件。这是从相关链接的perl脚本中得到的启发。
#!/usr/bin/env python
import os
import sys
from formatter import *
version = "0.1"
file = sys.argv[1]
new_file = "/tmp/html-markdown-alternative.html"
with open(file, "r") as f:
text = f.read()
lines = text.split('\n')
header = []
body = []
headerStart = True
for l in lines:
if headerStart:
m = re.search(r'^[\w\-]+\:', l)
if m:
header.append(l)
else:
headerStart = False
body.append(l)
else:
body.append(l)
header = '\n'.join(header)
body = '\n'.join(body)
htmlBody = markdownToHtml(body);
html = []
html.append('<html>')
html.append('<head>')
html.append('<meta name=\"generator\" content=\"text2mime-markdown{}\">'.format(version))
html.append('<style>')
html.append("code { font-family: 'Andale Mono', 'Lucida Console', \
'Bitstream Vera Sans Mono', 'Courier New', monospace; }")
html.append('pre { border-left: 20px solid #ddd; margin-left: 10px; \
padding-left: 5px; }')
html.append('</style>')
html.append('</head>')
html.append('<body>')
html.append('{0}'.format(body))
html.append('</body>')
html.append('</html>')
html = '\n'.join(html)
with open(new_file, "w") as newF:
newF.write(html)
with open(file, 'w') as f:
f.write(header)
这取决于另一个名为python的python文件formatter.py，该文件pandoc用于格式化我的邮件，但如果pandoc不可用，则可以使用python-markdown2包。该脚本如下。
