clang-check
Clang-based static analysis and AST inspection tool
TLDR
Run static analysis on a source file
$ clang-check [source.cpp]
Check with specific compiler flags$ clang-check [source.cpp] -- [--std=c++17] [-I/include/path]
Run analysis with AST dump$ clang-check -ast-dump [source.cpp]
Analyze using compilation database$ clang-check -p [build/] [source.cpp]
SYNOPSIS
clang-check [options] source-files [--] [compiler-options]
DESCRIPTION
clang-check is a tool for running Clang-based static analysis on C/C++ source files. It performs syntax checking, type checking, and can dump the Abstract Syntax Tree (AST) for inspection.
Part of the LLVM/Clang toolchain, it's useful for quick validation and AST exploration without full compilation.
PARAMETERS
-p path
Path to compilation database (compile_commands.json).-ast-dump
Dump the AST to stdout.-ast-list
List AST nodes.-ast-print
Pretty-print the AST.-analyze
Run static analysis.
CAVEATS
Requires Clang to be installed. For project-wide analysis with correct include paths, use a compilation database (compile_commands.json).
