# Wrapper of clang-tidy
|
|
|
|
# Use case #1: by RBE input processor to get resource dir.
|
|
# Command:
|
|
# clang-tidy.sh --version -- -print-resource-dir
|
|
# Outputs:
|
|
# same as clang-tidy --version -- -print-resource-dir
|
|
|
|
# Use case #2: by soong generated ninja build rules.
|
|
# Calls clang-tidy and touch output .tidy file.
|
|
# Calls clang or clang++ to generate .tidy.d file.
|
|
# Environment:
|
|
# CLANG_CMD: 'clang' or 'clang++'
|
|
# TIDY_FILE: path to output .tidy file
|
|
# TIDY_TIMEOUT: optional for clang-tidy
|
|
# Arguments: # same as clang-tidy
|
|
# <in-file-path> (required, input file)
|
|
# <clang-tidy flags> (optional)
|
|
# "--" (required to separate arguments)
|
|
# <clang/clang++ flags> (optional)
|
|
# Outputs:
|
|
# .../*.tidy (the output file)
|
|
# .../*.tidy.d (the dependent file is output file plus .d suffix)
|
|
# stdout and stderr from clang-tidy
|
|
# stdout and stderr from clang/clang++ if clang-tidy succeeds
