Flycheck syntax checker using clang-tidy
This library provides a flycheck checker for C/C++ source code using clang-tidy.
You'll need Emacs 24 for flycheck, so the recommended way to get
flycheck-clang-tidy is as a package from the MELPA
repository.
Alternatively you have to ensure flycheck is installed, then
download this code and add the directory to your Emacs load-path.
Then, in your init.el:
(eval-after-load 'flycheck
'(add-hook 'flycheck-mode-hook #'flycheck-clang-tidy-setup))Or, if you use use-package:
(use-package flycheck-clang-tidy
:after flycheck
:hook
(flycheck-mode . flycheck-clang-tidy-setup)
)Make sure that the clang-tidy binary is present on Emacs' exec-path, or
customize flycheck-clang-tidy-executable to point to the clang-tidy
binary.
When flycheck is enabled (e.g. with global-flycheck-mode), c-mode and
c++-mode buffers will be automatically checked using this checker.
To have clang-tidy work correctly, you usally require a compile command
database as described in clang-tidy --help. For example using CMake a file
named compile_commands.json can be created using
-DCMAKE_EXPORT_COMPILE_COMMANDS=ON. flycheck-clang-tidy then looks for this
file via variable flycheck-clang-tidy-build-path which defaults to build.
You can pass additional options to clang-tidy using the variable
flycheck-clang-tidy-extra-options.
