pocketberserker / diff.match.patch Goto Github PK

Please make DiffLinesToChars and DiffCharsToLines methods public so it would be possible to do a line diff as described here https://github.com/google/diff-match-patch/wiki/Line-or-Word-Diffs.

I'd like to use this great library to help with failing unit tests comparing expected/actual string values.

I'd like the diff to be pretty printed pretty much like github shows with each line prefixed with + and - and few lines of context around each diff.

I figured out how to use the library to get the list of diff but couldn't figure out how to implement the appropriate pretty-printing to do what I described.

I'd appreciate minimal code sample to do that!

I am comparing two string

problem is that not get expected output

when I enter run time:

This is my testing for matching algoritham - first string

This is my testing for matchings algoritham for application by website - second string

see my output:

when I remove the is keyword then I dont want to display in param1:

what I want to:

testing matching
testings matchings

            var slist = stextbox.Text.Split(' ');
            var flist = ftextbox.Text.Split(' ');

            int minWordCount = Math.Min(slist.Length, flist.Length);

            var diffWords = slist.Take(minWordCount).Where(x => flist.Contains(x) == false).ToList();

            var diffWordsf = flist.Take(minWordCount).Where(x => slist.Contains(x) == false).ToList();

           Label2.Text = "param2:" + string.Join("  ", diffWords);

            Label1.Text = "param1:" + string.Join("  ", diffWordsf);
        } 
     }

The code requires the FSharp.Core library which hasn't been referenced after adding Diff.Match.Patch to my project using NuGet.

There might be a missing dependency information in the .nuspec file.
