C++ Error Simplifier

C++ Error Simplifier

Stop digging through pages of C++ compiler output.

C++ Error Simplifier turns long, complex MSVC diagnostics into a short explanation of the root cause and a practical suggested fix.

It is especially useful for errors involving templates, concepts, type mismatches, overload resolution, and deeply nested compiler messages.

What it does

• Reads the selected C++ compiler diagnostic
• Extracts the relevant error context
• Simplifies noisy MSVC output
• Shows a concise root-cause explanation
• Suggests a practical fix
• Preserves source locations for quick navigation

How to use it

Select a compiler error or diagnostic in Visual Studio and run C++ Error Simplifier.

The extension analyzes the diagnostic and displays a cleaner explanation instead of forcing you to manually trace through long template-instantiation chains and repeated compiler output.

Requirements

• Visual Studio 2022 or later
• GitHub Copilot CLI installed
• GitHub Copilot CLI authenticated and ready to use

Privacy

C++ Error Simplifier uses the locally installed GitHub Copilot CLI to process compiler diagnostics.

The diagnostic text required for the explanation may therefore be processed by GitHub Copilot according to your GitHub account, Copilot configuration, and applicable GitHub terms and privacy policies.

Best suited for

• Template errors
• C++ concepts and constraints
• Type conversion problems
• Overload-resolution failures
• Nested STL diagnostics
• Long MSVC compiler errors

Less compiler noise. Faster root cause.
