2016-03-28type safe targets for propertiesJoey Hess
* Property types have been improved to indicate what systems they target. This prevents using eg, Property FreeBSD on a Debian system. Transition guide for this sweeping API change: - Change "host name & foo & bar" to "host name $ props & foo & bar" - Similarly, `propertyList` and `combineProperties` need `props` to be used to combine together properties; they no longer accept lists of properties. (If you have such a list, use `toProps`.) - And similarly, Chroot, Docker, and Systemd container need `props` to be used to combine together the properies used inside them. - The `os` property is removed. Instead use `osDebian`, `osBuntish`, or `osFreeBSD`. These tell the type checker the target OS of a host. - Change "Property NoInfo" to "Property UnixLike" - Change "Property HasInfo" to "Property (HasInfo + UnixLike)" - Change "RevertableProperty NoInfo" to "RevertableProperty UnixLike UnixLike" - Change "RevertableProperty HasInfo" to "RevertableProperty (HasInfo + UnixLike) UnixLike" - GHC needs {-# LANGUAGE TypeOperators #-} to use these fancy types. This is enabled by default for all modules in propellor.cabal. But if you are using propellor as a library, you may need to enable it manually. - If you know a property only works on a particular OS, like Debian or FreeBSD, use that instead of "UnixLike". For example: "Property Debian" - It's also possible make a property support a set of OS's, for example: "Property (Debian + FreeBSD)" - Removed `infoProperty` and `simpleProperty` constructors, instead use `property` to construct a Property. - Due to the polymorphic type returned by `property`, additional type signatures tend to be needed when using it. For example, this will fail to type check, because the type checker cannot guess what type you intend the intermediate property "go" to have: foo :: Property UnixLike foo = go `requires` bar where go = property "foo" (return NoChange) To fix, specify the type of go: go :: Property UnixLike - `ensureProperty` now needs to be passed a witness to the type of the property it's used in. change this: foo = property desc $ ... ensureProperty bar to this: foo = property' desc $ \w -> ... ensureProperty w bar - General purpose properties like cmdProperty have type "Property UnixLike". When using that to run a command only available on Debian, you can tighten the type to only the OS that your more specific property works on. For example: upgraded :: Property Debian upgraded = tightenTargets (cmdProperty "apt-get" ["upgrade"]) - Several utility functions have been renamed: getInfo to fromInfo propertyInfo to getInfo propertyDesc to getDesc propertyChildren to getChildren * The new `pickOS` property combinator can be used to combine different properties, supporting different OS's, into one Property that chooses which to use based on the Host's OS. * Re-enabled -O0 in propellor.cabal to reign in ghc's memory use handling these complex new types. * Added dependency on concurrent-output; removed embedded copy.

2015-09-29add Maintainer entries for contributed modulesJoey Hess
These show up in the haddock documentation on the sidebar. The author emails are not hyperlinked, so hopefully this is not a spam source. Keeping track of Maintainers of modules is becoming necessary because I don't use all these modules and am not the best person to maintain them, beyond simple changes to keep them building. I'll loop in the Maintainer if there's a bug etc on their module.
