轉化爲結構化的標準xhtml或html。markdown最初用perl寫成,後來移植到python,java,php.這裏主要
介紹下python-markdown的用法。
python-markdown模塊使用有兩個模式,一種是做爲獨立的命令行,另外一種是做爲python的模塊使用。
1. 命令行模式
在Fedora下,命令行名稱是markdown:
[ray@localhost markdown]$ markdown
Usage: markdown INPUTFILE [options]
Options:
-h, --help show this help message and exit
-f OUTPUT_FILE, --file=OUTPUT_FILE
write output to OUTPUT_FILE
-e ENCODING, --encoding=ENCODING
encoding for input and output files
-q, --quiet suppress all messages
-v, --verbose print info messages
-s SAFE_MODE, --safe=SAFE_MODE
same mode ('replace', 'remove' or 'escape' user's
HTML tag)
--noisy print debug messages
-x EXTENSION, --extension=EXTENSION
load extension EXTENSION
使用起來很簡單, 直接運行markdown input.txt > output.html即可。例如:
[ray@localhost markdown]$ cat notes.txt
Who am I?
===========
This is Ray Chen speaking.
Where am I from?
====================
I'm from SH, China. I love this place.
What's next?
=================
* nothing
* sleep
* study
* reading book
[ray@localhost markdown]$ markdown notes.txt > notes.html
[ray@localhost markdown]$ cat notes.html
<h1>Who am I?</h1>
<p>This is Ray Chen speaking.
</p>
<h1>Where am I from?</h1>
<p>I'm from SH, China. I love this place.
</p>
<h1>What's next?</h1>
<ul>
<li>
nothing
</li>
<li>
sleep
</li>
<li>
study
</li>
<li>
reading book
</li>
2. 模塊用法
[ray@localhost markdown]$ cat test_markdown.py
#!/usr/bin/python
import markdown
import codecs
# Open input file in read, utf-8 mode
input_file = codecs.open("notes.txt", mode="r", encoding="utf8")
text = input_file.read()
html = markdown.markdown(text)
print html
# Write string html to disk
output_file = codecs.open("notes_py.html", mode="w", encoding="utf8")
output_file.write(html)
[ray@localhost markdown]$ python test_markdown.py
<h1>Who am I?</h1>
<p>This is Ray Chen speaking.
</p>
<h1>Where am I from?</h1>
<p>I'm from SH, China. I love this place.
</p>
<h1>What's next?</h1>
<ul>
<li>
nothing
</li>
<li>
sleep
</li>
<li>
study
</li>
<li>
reading book
</li>
</ul>
[ray@localhost markdown]$ cat notes_py.html
<h1>Who am I?</h1>
<p>This is Ray Chen speaking.
</p>
<h1>Where am I from?</h1>
<p>I'm from SH, China. I love this place.
</p>
<h1>What's next?</h1>
<ul>
<li>
nothing
</li>
<li>
sleep
</li>
<li>
study
</li>
<li>
reading book
</li>
後記:
markdown工具在很多程序中用到,比如說wordpress, pybb等,特別適合wiki, blog,forum等。
