ComparePlus is a powerful, free plugin designed to offer advanced file comparison features right inside your Notepad++ editor.

Key Features of the ComparePlus Plugin

ComparePlus is not just a simple file comparison tool; it’s packed with features to handle various comparison needs:

• Side-by-Side File Comparison: The core feature, ComparePlus displays two files in adjacent panels, clearly highlighting the differences line by line. This visual approach makes it easy to spot changes, additions, and deletions at a glance.
• Selection-Based Comparison: Need to compare only specific sections of two files? ComparePlus allows you to select portions of text in each file and compare just those selections. This is incredibly useful for focusing on particular code blocks or text segments.
• Find Unique Lines: Beyond just showing differences, ComparePlus can identify lines that are unique to each file. This is invaluable for tasks like merging lists or isolating specific entries in datasets.
• Integration with Git and SVN: For developers, ComparePlus offers seamless integration with version control systems. You can directly compare a file against its Git or SVN repository version, making it easy to track changes and revisions within your projects. This feature relies on libgit2 and sqlite libraries for robust version control interaction.
• Compare Against Last Saved Version: Ever make changes and wish you could quickly see what you altered since the last save? ComparePlus lets you diff the current file against its previously saved state, perfect for reviewing recent edits.
• Clipboard Comparison: Compare text directly from your clipboard against a file or a selection within a file. This is handy for quickly comparing snippets of text copied from websites, emails, or other applications.
