Windows diff patch

It makes changes visible and helps you understand them. In this article, we've compiled a short list that helps you get an overview of the best diff tools on Windows. Being free and open source , Meld is a very popular tool on Windows it's also available for Linux.

It supports three-way comparing and merging and lets you edit files directly from the comparison view. Apart from diffing files , Meld also supports comparison of folders. It goes well beyond pun intended diffing simple text and also allows comparing PDF, Excel and image files. The "Pro" version also includes a solid three-way merge. Just like Beyond Compare, Araxis Merge supports more than just text and image files.

It comes in standard and professional editions, and for people working on both Windows and macOS, it's good to know that a single license is valid for both platforms. Another free and open source tool answers to the name of KDiff3. The project hasn't seen many updates in recent years though you may be able to find more recent releases through this page , but it remains a solid diff and merge tool that should satisfy basic needs.

Much like Araxis, the DeltaWalker diff tool also lets you compare office files. If you're regularly performing comparisons on a folder basis, it's good to know that DeltaWalker shines with great performance in this area.

Perforce , the company best known for its enterprise version control platform, also offers a solid diff tool: P4Merge is free of charge and comes with a basic feature set that makes it an interesting option on Windows, macOS and Linux. Reason 1 : diff can be useful by itself to see what has changed between files, even if you never use patch.

Reason 2 : Sometimes you can get patches from third parties and apply them to your files. This can be beneficial in cases when the files being patched are large, but the number of changes is relatively small: transferring a patch file is more efficient than transferring the entire file.

Reason 3: You can apply patches to files that don't perfectly match the original file used in diff. For example, if you use a CMS with a configuration file, and make local modifications to that configuration file, you want to preserve those local changes when you upgrade your CMS.

Copying the vendor's new configuration over your version will lose your changes. However, in many cases, you can still safely use patch to apply the vendor's changes from the most recent version without losing your own changes. For example, if you have an original file, then make some changes and save it under another name, you could compare the two using diff.

The basic diff syntax looks like this:. This command sets up the basic structure for comparing one file to another. There are also options to add more functionality to a command. Replace [original filename] and [changed filename] with the actual names of the files. Be sure to include the file extensions with the file names.

A basic diff command without options may look something like this:. In this example, the command would compare file1. However, options will change the command syntax a little. You can also combine multiple options in one command. It will end up looking something like this:. You may also see a variation that gives each option its own dash -. Both methods of adding multiple options are valid. See below for a list of commonly used options:.

For more options, see this list of diff options by GNU. When a diff command is run, the basic output will look similar to this:. Using the -y option will change how the output is displayed.

Instead, diff compares and pulls the changes out for you to view. The header should be something like view it in Notepad or your fav text editor :. For Java projects, I have used NetBeans to apply patch files.

If the Java code you are patching is not already a NetBeans project, create a project for it. To create a new project:. Note that these will commit the changes by default; you can avoid this using hg import --no-commit option if using the command-line, or if you used Hg Workbench, you might find it useful to issue hg rollback after the merge. When applying patches using TortoiseSVN, I typically save the path in the root of the checked out repository.

ApplyPatch should automatically figure out which level in the directory hierarchy the patch was created. I have, however, had issues in the past with applying patches that contain new files, or which involve renames to files. Unicode can give you similar issues. Do you have two monitors? I was having the same issue with TortoiseMerge and I realized that when I disabled one of the monitors the little window with the file list showed up.

Hope this helps you. A BusyBox port for Windows has both a diff and patch command, but they only support unified format.
