Webpage2html

 

save/convert web pages to a standalone editable html file for offline archive/view/edit/play.

Build Status

Webpage2html: Save web page to a single html file

This is a simple script to save a web page to a single html file. No mhtml or pdf stuff, no xxx_files directory, just one single readable and editable html file.

The basic idea is to insert all css/javascript files into html directly, and use base64 data URI for image data.

Usage and Example

Save web page directly from url (recommended way):

$ python webpage2html.py https://www.google.com > google.html

or save web page first using browsers such as Chrome, to something.html with something_files directory beside.

$ python webpage2html.py /path/to/something.html > something_single.html

But note that the second method may not always work as expected, because there may be urls like //ssl.gstatic.com/gb/images/v1_c69d5271.png (from google index page), but the file is missing in Google_files directory saved by browsers.

Enable javascript, for example, save 2048 game page into a single html for offline playing

$ python webpage2html.py -s http://gabrielecirulli.github.io/2048/ > 2048.html

Dependency

BeautifulSoup4, lxml, termcolor(optional)

$ pip install -r requirements.txt

or install them manually

$ pip install lxml BeautifulSoup4 requests termcolor

I have tried the default HTMLParser and html5lib as the backend parser for BeautifulSoup, but both of them are buggy, HTMLParser handles self closing tags (like <br> <meta>) incorrectly(it will wait for closing tag for <br>, so If too many <br> tags exist in the html, BeautifulSoup will complain RuntimeError: maximum recursion depth exceeded), and html5lib will encode encoded html entities such as &lt; again to &amp;lt;, which is definitly unacceptable. I have tested many cases, and lxml works perfectly, so I choose to use lxml now.

The termcolor package is for colored log output support if you like.

Unsupported Cases

browser side less compiling

The page embeds less css directly and use less.js to compile in browser. In this case, I still cannot find a way to embed the less code into generated html to make it work.

<link rel="stylesheet/less" type="text/css" href="http://dghubble.com/blog/theme/css/style.less">
<script src="http://dghubble.com/blog/theme/js/less-1.5.0.min.js" type="text/javascript"></script>

srcset attribute in img tag (html5)

Currently srcset is discarded.
