我正在尝试为clang-tidy创建一个自定义cmake目标,以便对我的项目进行lint。源文件夹看起来像这样:
src/scripts/run-clang-tidy.py
src/.clang-tidy
src/...
到目前为止,我的计划是使用自定义命令将这两个文件复制到构建目录:
add_custom_command(
OUTPUT run-clang-tidy.py .clang-tidy
COMMAND cp ${CMAKE_SOURCE_DIR}/scripts/run-clang-tidy.py ${CMAKE_SOURCE_DIR}/.clang-tidy ${CMAKE_CURRENT_BINARY_DIR})
我现在想在构建目录(应该是工作目录)中使用自定义目标调用run-clang-tidy.py
,以便我可以调用:
make lint
哪个应运行.clang-tidy
中指定的检查。
要使此脚本生效,它还需要CMAKE_EXPORT_COMPILE_COMMANDS
选项。我尝试使用以下命令设置它,但它无法识别它:
add_definitions(-DCMAKE_EXPORT_COMPILE_COMMANDS=ON)
add_custom_target
的调用怎么样?

答案 1 :(得分:10)
我可以建议另一种方法,不需要额外的Python脚本。
首先,我想在自定义CMake规则中集成clang-tidy
和clang-format
,因此我首先生成了位于根目录下的.clang-tidy
和.clang-format
个文件该项目。
要生成.clang-tidy
,请先找到适合您项目的选项,然后执行以下操作:
$> clang-tidy <source-files> -dump-config <tidy-options> -- <compile-options> > .clang-tidy
对于clang-format
,您可以使用-style=xxx
选项以默认样式开头,然后将其转储。例如,从LLVM样式开始:
$> clang-format -style=LLVM -dump-config > .clang-format
然后,编辑它并根据需要正确配置它。看起来应该是这样的:

CMake允许以非常简单的方式定义自定义规则,您只需要通过调用add_custom_target()
过程在文件中编写一组CMake命令,然后将其包含在{{1文件。这就是我们要做的,我们首先在项目的根目录创建一个CMakeList.txt
文件:
cmake/clang-dev-tools.cmake
然后,编辑# Additional target to perform clang-format/clang-tidy run
# Requires clang-format and clang-tidy
# Get all project files
file(GLOB_RECURSE ALL_SOURCE_FILES *.cpp *.hpp)
add_custom_target(
clang-format
COMMAND /usr/bin/clang-format
-style=file
-i
${ALL_SOURCE_FILES}
)
add_custom_target(
clang-tidy
COMMAND /usr/bin/clang-tidy
${ALL_SOURCE_FILES}
-config=''
--
-std=c++11
${INCLUDE_DIRECTORIES}
)
并添加:
CMakeLists.txt
然后,一旦构建系统重新生成,您应该能够运行# Including extra cmake rules
include(cmake/clang-dev-tools.cmake)
和make clang-tidy
。

Alexander Shukaev提到的文档有点细节,所以我添加了一个例子。警告字符串的格式化使IDE认为铿锵有力的结果是编译器警告,并将标记源代码。此外,它在创建目标文件后并行运行每个文件。
public class Foo {
public static void main (String[] args) {
int[] values = {1,2,3}; //1
int[] list = new int[3]; //2
list[0] = 1;
list[1] = 2;
list[2] = 3;
}
}
我遇到的唯一问题是,它仍会检查自动生成的if ( CMAKE_VERSION GREATER "3.5" )
set(ENABLE_CLANG_TIDY OFF CACHE BOOL "Add clang-tidy automatically to builds")
if (ENABLE_CLANG_TIDY)
find_program (CLANG_TIDY_EXE NAMES "clang-tidy" PATHS /usr/local/opt/llvm/bin )
if (CLANG_TIDY_EXE)
message(STATUS "clang-tidy found: ${CLANG_TIDY_EXE}")
set(CLANG_TIDY_CHECKS "-*,modernize-*")
set(CMAKE_CXX_CLANG_TIDY "${CLANG_TIDY_EXE};-checks=${CLANG_TIDY_CHECKS};-header-filter='${CMAKE_SOURCE_DIR}/*'"
CACHE STRING "" FORCE)
else()
message(AUTHOR_WARNING "clang-tidy not found!")
set(CMAKE_CXX_CLANG_TIDY "" CACHE STRING "" FORCE) # delete it
endif()
endif()
endif()

add_definitions
设置 CMake 变量,仅限配置阶段。如果要为构建阶段执行的命令设置 environment 变量,请使用COMMAND
关键字的相应shell机制:
add_custom_target(lint
COMMAND CMAKE_EXPORT_COMPILE_COMMANDS=ON python run-clang-tidy.py
DEPENDS ${CMAKE_CURRENT_BINARY_DIR}/run-clang-tidy.py
${CMAKE_CURRENT_BINARY_DIR}/.clang-tidy
为COMMAND
关键字指定的所有内容都将由shell“按原样”解释(在解释CMake之后,这里是no-op)。
