cmake获取svn版本信息

说明

通过cmake在编译阶段获取svn版本信息，并生成宏提供代码使用

获取svn信息

cmake获取svn信息，并定义宏

if(UNIX)
	# 获取svn信息，svn info 可以填相对/绝对路径或者远程地址
	execute_process(COMMAND svn info http://192.168.6.124/usvn/public/svn/develop_cpp
					COMMAND grep -E "Rev:|Author:|Date:"
					COMMAND cut -d " " -f 4
					TIMEOUT 3
					OUTPUT_VARIABLE SvnData)
	# 拆分信息
	string(REPLACE "\n" ";" SEXY_LIST ${SvnData})
	list(GET SEXY_LIST 0 SvnAuthor)
	list(GET SEXY_LIST 1 SvnRev)
	list(GET SEXY_LIST 2 SvnDate)
	message(STATUS "SvnAuthor: ${SvnAuthor}")
	message(STATUS "SvnRev: ${SvnRev}")
	message(STATUS "SvnDate: ${SvnDate}")
	# 定义宏
	target_compile_definitions(${PROJECT_NAME} PUBLIC SVN_REV=${SvnRev})
	target_compile_definitions(${PROJECT_NAME} PUBLIC SVN_AUTHOR=${SvnAuthor})
	target_compile_definitions(${PROJECT_NAME} PUBLIC SVN_DATE=${SvnDate})
endif()

使用svn信息宏

c++打印svn信息

#ifndef WIN32
#	define MACRO_(v) #v
#	define SHOWMACOR(v) MACRO_(v)
    LogDebug("=============Svn Info===============");
    LogDebug("Last Changed Author: {}", SHOWMACOR(SVN_AUTHOR));
    LogDebug("Last Changed Rev: {}", SHOWMACOR(SVN_REV));
    LogDebug("Last Changed Date: {}", SHOWMACOR(SVN_DATE));
#endif    // !1
