Visual Comparer is intended mainly for software and web site developers that require dedicated text editor with syntax highlighting and visual comparison feature. However, the application can be used by anyone who has to deal with several versions of the same text file. Visual Comparer is highly configurable, allowing customization of nearly every single part of the interface. Besides that, Visual Comparer supports plug-in architecture, which in turn allows end users expand the program functionality by adding new syntax highlighting patterns. The ability to display line numbers and create custom bookmarks makes navigating text documents real easy, while the reporting feature allows for creation of printable HTML reports covering all the differences between files.
