Notepad++ is a powerful and popular text editor favored by many for its lightweight nature and extensive plugin ecosystem. When working with code or text documents, the need to Compare Two Files In Notepad++ to identify differences is a common task. While Notepad++ itself doesn’t have a built-in file comparison feature, it thankfully offers plugins like ComparePlus to bridge this gap. This article delves into how you can effectively compare two files in Notepad++ using the ComparePlus plugin and explores its functionalities, limitations, and potential workarounds.
Utilizing the ComparePlus Plugin for File Comparison
ComparePlus is a plugin for Notepad++ designed to facilitate file comparison directly within the editor. It allows you to visually identify the differences between two files side-by-side, highlighting additions, deletions, and modifications.
To start comparing two files in Notepad++ with ComparePlus, you would typically:
- Install the ComparePlus plugin: If you haven’t already, you can install ComparePlus through Notepad++’s Plugin Manager. Navigate to
Plugins > Plugins Admin, search for “ComparePlus”, and install it. - Open the two files: Open the two files you wish to compare in Notepad++.
- Initiate the comparison: Go to
Plugins > ComparePlus > Compare. This will typically split your Notepad++ window and display the two files side by side with differences highlighted.
ComparePlus provides visual cues to differentiate between the files:
- Lines present only in the first file might be highlighted in one color.
- Lines present only in the second file in another color.
- Modified lines are usually marked with a different color or style, indicating changes within the lines themselves.
Understanding the “Copy Diffs” Limitation in ComparePlus
A user might expect a feature to directly “copy all diffs” – meaning extracting only the lines that are different between the two files. However, as highlighted in the original discussion, ComparePlus, unfortunately, doesn’t offer a straightforward “copy all diffs” command.
While ComparePlus excels at visually presenting the differences, directly copying only the differing lines isn’t a built-in function. Buttons like “Next” and “Previous” in the ComparePlus toolbar section allow you to navigate through each difference, enabling manual copying of those specific lines if needed.
The “Show Only Diffs” feature (Plugins > ComparePlus > Show Only Diffs) is available to filter the view and display only the lines that are different. However, even with “Show Only Diffs” active, using Ctrl+A, Ctrl+C to copy content will still copy all lines from the file, including the hidden, non-differing lines, not just the visible differences.
Workarounds and Alternative Approaches
Despite the lack of a direct “copy all diffs” feature, there are a few approaches you can consider when you need to work with the differences identified by ComparePlus:
-
Manual Copying with Navigation: Utilize the “Next” and “Previous” difference buttons in the ComparePlus toolbar to step through each change. Manually select and copy the lines you need as you navigate. This is suitable when you only need to extract a few specific differences.
-
Screenshot and Re-typing (For Small Differences): If the differences are minimal and primarily for documentation or quick reference, taking a screenshot of the ComparePlus view highlighting the differences might be a quick visual capture method. You could then manually re-type the necessary parts if needed, although this is not ideal for larger sections of differing code or text.
-
Consider External Diff Tools for Advanced Merge Needs: For users requiring more advanced features like merging differences or generating detailed diff reports, dedicated diff and merge tools might be more appropriate. Tools like TortoiseMerge (mentioned in the original text, often used with TortoiseSVN for version control) or other standalone diff/merge utilities offer functionalities beyond basic visual comparison, including “merge” capabilities to integrate changes between files and generate diff reports in standard formats. These tools often provide options to copy or export differences in various formats, which might be closer to a “copy all diffs” functionality.
Feature Requests and the Future of ComparePlus
The original discussion touches upon the idea of “merge” features and exporting diff reports. Many compare tools in other environments do offer capabilities to not just view differences but also to merge them – allowing users to selectively apply changes from one file to another.
Requesting features like “merge” functionalities or a “copy diffs” option directly to the ComparePlus plugin developers could be valuable. Checking the plugin’s issue tracker (often found on platforms like GitHub if the plugin is open source) or community forums to see if similar feature requests exist and adding your voice can help prioritize future development.
Conclusion
While ComparePlus for Notepad++ is a very useful plugin for visually comparing two files in Notepad++ and identifying differences, it currently lacks a direct “copy all diffs” feature. Users can utilize workarounds like manual copying while navigating differences or consider external diff/merge tools for more advanced needs. Understanding the current limitations and exploring alternative solutions or feature requests ensures you can effectively manage file comparisons in your workflow.
