Awesome Clang

Useful resources and samples for using Clang-related tools, or for building stuff on top of Clang.

*Inspired by the awesome list thing.

Tools

clang-format

• clang-format docs - A tool to format C/C++/Java/JavaScript/Objective-C/Protobuf code.
• style options - clang-format style options.
• configurator - clang-format configurator.

clang-tidy

• clang-tidy - clang-based C++ linter tool.
• List of clang-tidy checks
• Writing a basic clang static analysis check

pp-trace

• pp-trace - tool that traces preprocessor activity.

Clang static analyzer

• Clang Static Analyzer - a source code analysis tool that finds bugs in C, C++, and Objective-C programs.
• scan-build -Running the analyzer from the command line.
• Static Analysis with clang
• CodeChecker - defect database and viewer extension for Clang Static Analyzer.
• clang-analyzer-guide An easy guide to Clang Static Analyzer extension.

AddressSanitizer

• AddressSanitizer - a fast memory error detector.
• Address Sanitizer - overview by Mike Ash.

Other Clang-based tools

• C++ Insights - a clang-based tool which does source to source transformation. Its goal is it to make things visible which normally, and intentionally, happen behind the scenes. Live/online demo available.
• Clang Power Tools - Visual Studio extension with Clang/LLVM tools (clang++, clang-tidy and clang-format).

Libraries

LibClang

• libclang: - C Interface to Clang.
• Introduction to libclang
• LLVM & Clang library usage samples
• lloccount - C/C++ Logical Lines Of Code Counter.
• libclangmm - C++-wrapper for libclang (developed for juCi++)
• Customizable Naming Convention Checker - similar to clang-format, but for naming conventions only.
• irony-mode - A C/C++ minor mode for Emacs powered by libclang.
• c99-to-c89 - Tool to convert C99 code to MSVC-compatible C89.
• ClangKit - Objective-C frontend to LibClang.
• Skipping library code in gdb with help from libClang - using libClang’s Python bindings.

LibTooling

• LibTooling - library to support writing standalone tools based on Clang
• Tutorial for building tools using LibTooling and LibASTMatchers
• Modern source-to-source transformation with Clang and libTooling
• AST matchers and Clang refactoring tools
• Compilation databases for Clang-based tools
• LibTooling Example

Important Clang concepts

• Quick overview of how Clang works internally
• Getting Started with LLVM Core Libraries - PacktPub books can be a bit hit and miss, but this one is excellent. (A PDF with updates for Clang 3.5 is available for free download).
• Introduction to the Clang AST - a gentle introduction to the mysteries of the Clang AST.
• Matching the Clang AST - how to use Clang’s LibASTMatchers to match interesting nodes of the AST and execute code that uses the matched nodes.
• AST Matcher Reference - AST matchers implemented by Clang.
• How to build LLVM from source - Step-by step, using the GitHub mirror.
• Writing LLVM Pass in 2018 — Part I - New Pass & Pass Manager in a Peek.
• The future of Clang-based tooling

Videos
