Are you fixing the same bug over and over again?

This replicated code is a nightmare for development teams since nobody knows for certain where duplications exist. A critical bug is fixed once only to pop up again in another place – often in a serious customer situation. Merging enhancements and fixes across all branches and versions becomes impossible, especially when dealing with open source updates. And to make this problem even harder, most code replications include insertions, deletions, different variable names and other changes. When you’re looking for replicated code, it can be impossible to find using traditional keyword-based search methods.

Find once, fix everywhere

• Quickly find all instances of a known defect - even if it has been modified - across an entire codebase including all branches
• Identify similarities and differences in source code to enable refactoring and code merge operations
• Simplify ongoing maintenance by identifying duplicate and similar code sequences that can be extracted into libraries
• Ensure open source applications are completely synched with public releases

Pattern Insight fits into your existing development environments

When it comes to source code, Pattern Insight is intelligent. Because we understand and leverage syntax, Pattern Insight is able to parse code and find patterns that traditional search approaches can’t – for example “x = foo (y)” is the same pattern as “a = foo (b)”.

Pattern Insight is able to recognize code that is alike even if variable names, function names, or parameter options have been renamed. We can even understand code similarities that have statements inserted between them. We can identify the common pattern between “x = foo (y); z = x*20” and “a = foo (b); e = b; c = a*20”.
