Hi @BlackKite84 can you produce a jsfiddle with the problem?

BlackKite84 commented 9 years ago

http://jsfiddle.net/pytm9ueL/1/

yes

arnab commented 9 years ago

Huh, I am missing something here. You specified (in that jsfiddle):

arnab commented 9 years ago

Also, the "title" of this issue is set to <br>. Could you please change that to the actual problem/question you are reporting/asking?

BlackKite84 commented 9 years ago

unbenannt

I overwrite the change Content with the diff (i will see only change and original)

A new line (

arnab commented 9 years ago

Add debug: true to when you call prettyTextDiff: http://jsfiddle.net/pytm9ueL/4/

This will show you what this library found. Looks like the underlying Google diff-match-patch library shows the "↵ " also as a diff.

BlackKite84 commented 9 years ago

and why "Enter" i use Tab

arnab commented 9 years ago

Like I said, what you are seeing is coming from the underlying library. Please ask your question there: https://code.google.com/p/google-diff-match-patch/

I have Fix ist with

        } else {
          original = $(settings.originalContainer, this).text().trim();
          changed = $(settings.changedContainer, this).text().trim();
        }

I am running into the same issue that @BlackKite84 was seeing. I have two divs that appear to have identical content (including whitespace). If I pass parameters via originalContainer and changedContainer, PrettyTextDiff appears to pass slightly different strings (different in their whitespace) to google-diff-match-patch. Here is the result of a call to .prettyTextDiff( ) when I use originalContainer and changedContainer parameters. Note the <br>'s that are inserted at the beginning and end of .immutable-clause-pretty-diff

And here is the result of a call to .prettyTextDiff( ) when I use originalContent and changedContent parameters with the trim( ) function, as suggested by @BlackKite84. It works as expected:

It appears that if there are matching newline characters inside the originalContent and changedContent divs, google-diff-match-patch passes the newline character back, but PrettyTextDiff converts said newline character to a <br> here

I'm not sure if it would break things for other users, but it seems like substituting <br>s for newline characters may not be necessary.

I think that any problems like \t, \b, or whitespace would be solved by using <pre></pre>
