Clang-analyzer

clang-analyzer is a simple Python script that invokes clang++'s static analyzer with cross-translation unit support. It runs the steps described in the following web page:

https://clang.llvm.org/docs/analyzer/user-docs/CrossTranslationUnit.html

Usage

clang-analyzer [-p <compile_command.json_dir>] [--exclude=re] [c++ files...]

You must create a compile_commands.json file that lists the source files and its compile flags.

• The -p flag sets the directory that contains the compile_commands.json file. It defaults to '.'.

• All the c++ files in the commandline must appear in compile_commands.json.

• The --exclude flag sets the regexp patterns to exclude c++ files.
