GNU diffutils?

[goes2bob]

I am trying to create a "pretty" diff tool that uses the GNUWin32 diffutils. Color a lines that differs between two versions of the same file, another color for added lines to a file etc. I am not sure how to approach using the GNU tool within a QT4 program. I have a simple GUI, but I do not have any ideas about how to invoke the "diff" command of the tool OR how to use the output that the diffUtils will return.
I am developing for Windows, which "diff -y <directory1> <directory2>" in a dos shell produces an output like this:

where the "|" says that the lines are different , and ">" says that a line has been added to the file on the right.

You will have to use QProcess to run diff or any other tool.
Also, with QProcess, you can read the stdout of the process in a buffer.

You will still have to create a parser for that output.

Also, you are not necessarily obligated to use diff. A much easier way would be to "look" at the sources of WinMerge(www.winmerge.org), or any other open source diff tool, even"diff".
