bb.utils

• bitbake/lib 에 각종 bb util이 있다.
  • 레시피에서 from bb.utils import Class,Method... 등을 가져오면 된다.
    

bb.utils.lockfile

file_name = 'FILENAME'
lock = bb.utils.lockfile(file_name + '.lock')
with open(file_name, mode) as f:
    f.write(...)
bb.utils.unlockfile(lock)

bb.utils.contains('DISTRO_FEATURES', 'x11', 'true', 'false', d)

bb.data

bb.data.inherits_class('image',d))

• 해당 레시피가 이미지 레시피인지 여부 확인

import bb
print( bb.data.inherits_class('image', d) )
# === 출력 === #
True

bb.plain

bb.plain("string")

• 
• Recipe 개발 시 print에 유용함

• python Task, def PythonFunction 에서 print( ) 안됨
  • bb.plain( ) 사용할 것!
