# 1. 日志库
|
||
|
||
   日志库主要辅助调试和测试。
|
||
|
||
## 1.1. 基本需求：
|
||
|
||
1. 日志类型：info / error / warning / trace ；
|
||
2. 通过预编译选择开启 / 关闭；
|
||
3. 通过多态动态加载 / 卸载；
|
||
4. 通过预编译加载 / 卸载某个模块的日志；
|
||
|
||
## 1.2. 参考
|
||
|
||
* CMakeLists.txt脚本代码：
|
||
//build/global_config.cmake
|
||
```
|
||
// 文件名宏定义__F_FILE__，指定文件实现打印文件名 + 行号功能
|
||
// 不使用系统宏__FILE__是因为系统宏会打印绝对路径，日志阅读性差
|
||
function(define_file_name target)
|
||
get_target_property(source_files "${target}" SOURCES)
|
||
foreach(source_file ${source_files})
|
||
get_property(defs SOURCE "${source_file}"
|
||
PROPERTY COMPILE_DEFINITIONS)
|
||
get_filename_component(file_name "${source_file}" NAME)
|
||
list(APPEND defs "__F_FILE__=/"${file_name}/"")
|
||
set_property(
|
||
SOURCE "${source_file}"
|
||
PROPERTY COMPILE_DEFINITIONS ${defs})
|
||
endforeach()
|
||
endfunction()
|
||
// LOG_DISABLE日志使能宏，指定文件开启 / 关闭日志功能
|
||
function(log_disable target)
|
||
get_target_property(source_files "${target}" SOURCES)
|
||
foreach(source_file ${source_files})
|
||
get_property(defs SOURCE "${source_file}"
|
||
PROPERTY COMPILE_DEFINITIONS)
|
||
get_filename_component(file_name "${source_file}" NAME)
|
||
list(APPEND defs "LOG_DISABLE")
|
||
set_property(
|
||
SOURCE "${source_file}"
|
||
PROPERTY COMPILE_DEFINITIONS ${defs})
|
||
endforeach()
|
||
endfunction()
|
