propertyList :: Desc -> [Property] -> PropertySource
Combines a list of properties, resulting in a single property that when run will run each property in the list in turn, and print out the description of each as it's run. Does not stop on failure; does propigate overall success/failure.
combineProperties :: Desc -> [Property] -> PropertySource
Combines a list of properties, resulting in one property that ensures each in turn. Does not stop on failure; does propigate overall success/failure.
before :: Property -> Property -> PropertySource
Combines together two properties, resulting in one property that ensures the first, and if the first succeeds, ensures the second. The property uses the description of the first property.
flagFile :: Property -> FilePath -> PropertySource
Makes a perhaps non-idempotent Property be idempotent by using a flag file to indicate whether it has run before. Use with caution.
check :: IO Bool -> Property -> PropertySource
Makes a Property only need to do anything when a test succeeds.
trivial :: Property -> PropertySource
Marks a Property as trivial. It can only return FailedChange or NoChange.
Useful when it's just as expensive to check if a change needs to be made as it is to just idempotently assure the property is satisfied. For example, chmodding a file.
withOS :: Desc -> (Maybe System -> Propellor Result) -> PropertySource
Makes a property that is satisfied differently depending on the host's operating system.
Note that the operating system may not be declared for some hosts.
revert :: RevertableProperty -> RevertablePropertySource
Undoes the effect of a property.
host :: HostName -> HostSource
Starts accumulating the properties of a Host.
host "example.com" & someproperty ! oldproperty & otherproperty
(&) :: IsProp p => Host -> p -> HostSource
Adds a property to a Host
Can add Properties and RevertableProperties
(!) :: Host -> RevertableProperty -> HostSource
Adds a property to the Host in reverted form.
combineInfo :: (IsProp p, IsProp q) => p -> q -> InfoSource
combineInfos :: IsProp p => [p] -> InfoSource
makeChange :: IO () -> Propellor ResultSource
