假设我有事实文件:
code_in_git(a)
code_in_git(b)
code_in_git(c)
build_on_disk(a)
build_on_disk(c)
我想断言规则"如果code_in_git($branch)而不是build_on_disk($branc),则创建事实needs_build($branch)"。我该怎么做?
好吧,看来我可以用notany
:断言它们
no_build_on_disk
foreach
deploy.code_in_git($branch)
notany
deploy.build_on_disk($branch)
assert
deploy.needs_build($branch)
