diff

生成差异并输出Github风格的HTML。

>>> import ghdiff
>>> from six import print_
>>> print_(ghdiff.diff("a\nb", "b\nb"))
<style type="text/css">
...
</style>
<div class="diff">
    <div class="control">@@&nbsp;-1,2&nbsp;+1,2&nbsp;@@
    </div>
    <div class="delete">-a</div>
    <div class="">&nbsp;b</div>
    <div class="insert">+b</div>
</div>

css选项控制输出是否包含CSS。

>>> print_(ghdiff.diff("blah blah blah\nb", "blah zxqq blah\nb", css=False))
<div class="diff">
    <div class="control">@@&nbsp;-1,2&nbsp;+1,2&nbsp;@@
    </div>
    <div class="delete">-blah&nbsp;<span class="highlight">blah</span>&nbsp;blah</div>
    <div class="insert">+blah&nbsp;<span class="highlight">zxqq</span>&nbsp;blah</div>
    <div class="">&nbsp;b</div>
</div>

diff还接受表示行的字符串列表。

>>> print_(ghdiff.diff(["blah blah blah", "b"], ["blah zxqq blah", "b"]))
<style type="text/css">
...
</style>
<div class="diff">
    <div class="control">@@&nbsp;-1,2&nbsp;+1,2&nbsp;@@
    </div>
    <div class="delete">-blah&nbsp;<span class="highlight">blah</span>&nbsp;blah</div>
    <div class="insert">+blah&nbsp;<span class="highlight">zxqq</span>&nbsp;blah</div>
    <div class="">&nbsp;b</div>
