Google's library is awesome and can be fine- tuned in. API is a bit awkward, probably cause they. API in 8 different languages. Also, the library does not provide any beautification of the diff- ed. They provide a reference implementation (look for. In short, it tries to bridge the gap between the.
Diff, Match and Patch libraries for Plain Text. Project Home Downloads Wiki Issues Source.
A simple example is. Customizable options. Either mark up your HTML to use the default selectors, or use these options: optiondefaultexplanationoriginal. Container. original. CSS- selector for the element that holds the original text. See the demo for the effect.
I've been using the Python difflib, with the html output. This works well but difflib is not fast. I've a test case (see inline below) that is very slow with difflib, but the output is easy to read. When ran with dmp, it is. Diff match patch library is useful to compare the differences between the two texts.It compares the texts and displays what is added, removed or unchanged. We usePythonin our example below. Diff, Match and Patch Demo of Patch. Two texts can be diffed against each other, generating a list of patches. These patches can then be applied against a third text. If the third text has edits of its own, this version of. Google-diff-match-patch.
I'm not a front end designer, so I was wondering if anyone could recommend the most visually appealing way to represent a diff result in CSS/HTML (see the kind of results that diff

Plaintext : One method is to strip the tags from the HTML using a simple regex or node- walker. Then diff the HTML content against the text content.
Don't perform any diff cleanups. This diff enables one to map character positions from one version to the other (see the diff. After this, one can apply all the patches one wants against the plain text, then safely map the changes back to the HTML. The catch with this technique is that although text may be freely edited, HTML tags are immutable. Another method is to walk the HTML and replace every opening and closing tag with a Unicode character.
Check the Unicode spec for a range that is not in use. During the process, create a hash table of Unicode characters to the original tags. The result is a block of text which can be patched without fear of inserting text inside a tag or breaking the syntax of a tag. One just has to be careful when reconverting the content back to HTML that no closing tags are lost. I have a hunch that the 2nd idea, map- HTML- tags- to- Unicode- placeholders, might work better than one would otherwise guess..
Then, perform a plaintext diff. Finally, using the diff.
