[工具]-脚本自动化工具:按照linux kernel标准格式化输出文件(format_file)
小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
有時(shí)候?qū)懥艘欢盐募?#xff0c;從哪里抄來(lái)的，或者字節(jié)寫(xiě)的，沒(méi)有按照l(shuí)inux kernel的代碼標(biāo)準(zhǔn)，這時(shí)候手動(dòng)去改，非常繁瑣
.
寫(xiě)一個(gè)python腳本, 自動(dòng)將源代碼文件(如.c文件)格式化/規(guī)范化, 如刪除多余的空行空格, 按照l(shuí)inux kernel標(biāo)準(zhǔn)格式化.
當(dāng)前的使用方法 : python3 format.py 跟上文件名, 后續(xù)可擴(kuò)展對(duì)目錄下所有文件操作.
