python () is shorthand for "python __anonymous ()". It declares an anonymous function, which is executed automatically at the end of parsing. for example we can modify package version python __anonymous () { import bb, re new_version = '3.0.0' bb.data.setVar('PV',new_version,d) 本文来自ChinaUnix博客,如果查看原文请点:http://blog.chinauni...
