基于LLVM開(kāi)發(fā)Clang插件進(jìn)行代碼風(fēng)格檢查

摘要：其實(shí)和我還沒(méi)有好好研究過(guò)，之前大部分都是用開(kāi)發(fā)，代碼風(fēng)格檢查都是用的，所以這次選擇的代碼檢查作為開(kāi)始，通過(guò)實(shí)踐找找感覺(jué)和興趣，之后再一點(diǎn)一點(diǎn)精進(jìn)。

這個(gè)很多人都做過(guò)，文章也挺多的，我也是參考別人文章的，不過(guò)直到真正實(shí)現(xiàn)還是踩了許多坑，所以記錄下來(lái)，或許對(duì)其他人有幫助。其實(shí)LLVM和Clang我還沒(méi)有好好研究過(guò)，之前大部分都是用Swift開(kāi)發(fā)，代碼風(fēng)格檢查都是用的Swiftlint，所以這次選擇OC的代碼檢查作為開(kāi)始，通過(guò)實(shí)踐找找感覺(jué)和興趣，之后再一點(diǎn)一點(diǎn)精進(jìn)。

下載源碼

代開(kāi)終端

sudo mkdir llvm
sudo chown `whoami` llvm
cd llvm
export LLVM_HOME=`pwd`

git clone -b release_60 https://github.com/llvm-mirror/llvm.git llvm  
git clone -b release_60 https://github.com/llvm-mirror/clang.git llvm/tools/clang  
git clone -b release_60 https://github.com/llvm-mirror/clang-tools-extra.git llvm/tools/clang/tools/extra  
git clone -b release_60 https://github.com/llvm-mirror/compiler-rt.git llvm/projects/compiler-rt

下載源碼會(huì)比較慢，另外網(wǎng)上有其他文章，有的文章比較老，版本也比較老，建議用最新的release_60。

安裝cmake

如果沒(méi)有安裝cmake需要安裝一下，后面需要用。

brew update
brew install cmake

開(kāi)始編寫(xiě)插件

cd到llvm/llvm/tools/clang/examples

1.打開(kāi)這個(gè)目錄下的CMakeLists.txt文件，然后添加add_subdirectory(CodeChecker)

2.在當(dāng)前目錄創(chuàng)建新的文件夾CodeChecker，并cd到CodeChecker

mkdir CodeChecker
cd CodeChecker

3.在新建的CodeChecker目錄下創(chuàng)建三個(gè)文件

touch  CMakeLists.txt
touch  CodeChecker.cpp
touch  CodeChecker.exports

在新創(chuàng)建的CMakeLists.txt中添加

if( NOT MSVC ) # MSVC mangles symbols differently
  if( NOT LLVM_REQUIRES_RTTI )
    if( NOT LLVM_REQUIRES_EH )
      set(LLVM_EXPORTED_SYMBOL_FILE ${CMAKE_CURRENT_SOURCE_DIR}/CodeChecker.exports)
    endif()
  endif()
endif()

add_llvm_loadable_module(CodeChecker CodeChecker.cpp)

if(LLVM_ENABLE_PLUGINS AND (WIN32 OR CYGWIN))
  target_link_libraries(CodeChecker ${cmake_2_8_12_PRIVATE}
    clangAST
    clangBasic
    clangFrontend
    LLVMSupport
    )
endif()

在CodeChecker.cpp文件中加入

使用cmake編譯源代碼

1.cd到llvm，注意不是llvm/llvm，執(zhí)行

mkdir llvm_build && cd llvm_build
cmake -G Xcode ../llvm -DCMAKE_BUILD_TYPE:STRING=MinSizeRel

2.然后會(huì)在llvm_build文件目錄中看到LLVM.xcodeproj，用xcode打開(kāi)，選擇Automatically Create Schemes

3.編譯 clang，CodeChecker，libclang

4.在llvm_build/Debug/lib目錄下可以找到我們的插件，如下圖：

Xcode集成Plugin

創(chuàng)建需要加載插件的項(xiàng)目，在Build Settings欄目中的OTHER_CFLAGS添加上如下內(nèi)容：

-Xclang -load -Xclang (.dylib)動(dòng)態(tài)庫(kù)路徑 -Xclang -add-plugin -Xclang 插件名字

我把插件拷貝的桌面了，所以我的是：

-Xclang -load -Xclang /Users/roy.cao/Desktop/CodeChecker.dylib -Xclang -add-plugin -Xclang CodeChecker

然后你build項(xiàng)目，可能有unable to load plugin "/Users/roy.cao/Desktop/CodeChecker.dylib"的error，這是由于Clang插件需要對(duì)應(yīng)的Clang版本來(lái)加載，如果版本不一致會(huì)導(dǎo)致編譯錯(cuò)誤。

在Build Settings欄目中新增兩項(xiàng)用戶定義的設(shè)置，分別為CC和CXX CC對(duì)應(yīng)的是自己編譯的clang的絕對(duì)路徑，CXX對(duì)應(yīng)的是自己編譯的clang++的絕對(duì)路徑

/Users/roy.cao/llvm/llvm_build/Debug/bin/clang
/Users/roy.cao/llvm/llvm_build/Debug/bin/clang++

再build，會(huì)有以下錯(cuò)誤：

在Build Settings欄目中搜索index，將Enable Index-Wihle-Building Functionality的Default改為NO.

再build可能會(huì)出現(xiàn)一大堆系統(tǒng)庫(kù)的 symbol not found 錯(cuò)誤

這個(gè)時(shí)候需要在剛剛OTHER_CFLAGS的

-Xclang -load -Xclang /Users/roy.cao/Desktop/CodeChecker.dylib -Xclang -add-plugin -Xclang CodeChecker

后面再加上-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator12.0.sdk

注意iPhoneSimulator12.0.sdk，每個(gè)人的可能不同，需要到目錄下看看自己的版本。那么完整的就是下圖這樣：

再build就能做代碼風(fēng)格檢查啦，慶祝一下吧~~~~
