On windows, I have two source files and want to create a patch with difference, like this one. But I'm unsure, what format this patch is and what app to use in order to create it? GNU diff output is very different from the patch I can see in the link above.
Use File -> Open... to open the two versions for comparison. This will give you a nice view of what you have changed. Then do Tools -> Generate patch .... In the dialogue box, make sure you select Style: Unified in the Format box.
The patch file (also called a patch for short) is a text file that consists of a list of differences and is produced by running the related diff program with the original and updated file as arguments. Updating files with patch is often referred to as applying the patch or simply patching the files.
Try WinMerge. You'll find a patch generator in the "Tools" menu.
Thanks, PhiLho & Lukáš! The diff program from UnxUtils works great under Windows 7 to generate the patch file:
diff -u oldfile newfile >patchfile
Likewise, the patch program from UnxUtils works great to apply the patch:
patch -u oldfile patchfile
