Comparing files is a common task for developers, writers, and anyone who works with text documents. Notepad++, a popular free source code editor for Windows, offers a plugin called ComparePlus to help users identify differences between files. While ComparePlus is a useful tool, users often wonder about its capabilities, specifically concerning managing and copying these differences. This article explores how to Compare Files In Notepad++ using ComparePlus and discusses the options available for handling the identified discrepancies.
Understanding ComparePlus in Notepad++ for File Comparison
Notepad++ itself doesn’t have a built-in file comparison feature. To compare files, you need to install the ComparePlus plugin. Once installed, ComparePlus allows you to open two files side-by-side and visually highlight the differences between them. This is incredibly helpful for tasks like code review, document version control, or simply identifying changes you’ve made to a file.
However, a frequent question arises: “How do I copy only the differences between the files in Notepad++ ComparePlus?” Unfortunately, ComparePlus, at the time of writing, does not offer a direct “copy all differences” feature. This means there isn’t a single button or command to automatically extract and copy only the lines that are different between the compared files.
Navigating and Viewing File Differences in ComparePlus
Despite the lack of a direct “copy diffs” function, ComparePlus provides efficient ways to navigate and view the differences, which can indirectly help you manage them.
-
Next/Previous Difference Navigation: The ComparePlus toolbar includes “Next” and “Previous” buttons. These buttons are crucial for stepping through each identified difference between your files. By clicking these, you can quickly jump from one change to the next, visually inspecting each modification. This allows you to methodically review all discrepancies.
-
“Show Only Diffs” Feature: For a focused view, ComparePlus offers a “Show Only Diffs” option, accessible via Plugins > ComparePlus > Show Only Diffs or the “ShowOnlyDiffs” button on the toolbar. This feature filters the display to present only the lines that are different, hiding the identical content. This can be extremely useful when you want to concentrate solely on the modifications. However, it’s important to note that while “Show Only Diffs” visually isolates the changes, using
Ctrl+A, Ctrl+Cto copy the content will still copy all lines from the file, including the hidden identical lines, not just the displayed differences.
The Missing “Merge” Feature and the Need for Enhanced Difference Management
The original query implicitly points to a desire for more advanced difference management, similar to the “merge” functionalities found in dedicated comparison and version control tools like TortoiseDiff or TortoiseMerge. These tools often allow users to not only view differences but also to actively merge changes between files. Features like “Use Left Block” or “Use Right Block” enable users to selectively incorporate changes from one file into another, streamlining the process of reconciling different versions.
ComparePlus in Notepad++ currently lacks such direct merge capabilities. Users wanting to integrate changes typically need to manually copy lines from one file to the other based on the highlighted differences identified by ComparePlus. While functional, this manual process can be less efficient, especially when dealing with numerous or complex differences.
Feature Requests and Practical Workarounds for Managing Differences
Given the limitations, users seeking more advanced features like “copy diffs” or “merge” within Notepad++ ComparePlus should consider submitting a feature request to the plugin developers. Requesting features like a “copy all differences” command or, even better, merge functionalities similar to TortoiseMerge, could significantly enhance the plugin’s utility for a wider range of users.
In the meantime, practical workarounds for managing differences in Notepad++ using ComparePlus include:
- Manual Copy-Paste: Utilizing the “Next/Previous Difference” navigation to identify each change and then manually copying and pasting the desired lines between files. This is straightforward but can be time-consuming.
- Using “Show Only Diffs” for Review, then Manual Copy: Employing “Show Only Diffs” to get a focused view of changes, then manually copying relevant sections. Remember that
Ctrl+A, Ctrl+Cwill copy the entire file content, not just the visible differences. - Considering External Tools for Merging: For more complex merging tasks, especially in version control scenarios, consider using dedicated diff/merge tools like TortoiseDiff/TortoiseMerge, especially if you are already using TortoiseSVN for version control. These tools offer robust merge capabilities that go beyond basic file comparison.
Conclusion: Efficient File Comparison in Notepad++ with Room for Improvement
ComparePlus is a valuable Notepad++ plugin for visually identifying differences between files. While it effectively highlights changes and provides navigation tools to review them, it currently lacks features like directly copying only the differences or offering integrated merge functionalities. For users needing to simply compare and manually manage minor differences, ComparePlus offers a workable solution. However, for users seeking more advanced difference management and merging capabilities, exploring external dedicated tools or requesting enhanced features for ComparePlus would be beneficial. By understanding the current capabilities and limitations of ComparePlus, users can effectively leverage it for file comparison within Notepad++ and make informed decisions about their workflow.
