2015-10-27Explicit Info/NoInfo for RevertableProperty (API change)Joey Hess
RevertableProperty used to be assumed to contain info, but this is now made explicit, with RevertableProperty HasInfo or RevertableProperty NoInfo. Transition guide: - If you define a RevertableProperty, expect some type check failures like: "Expecting one more argument to ‘RevertableProperty’". - Change it to "RevertableProperty NoInfo" - The compiler will then tell you if it needs "HasInfo" instead. - If you have code that uses the RevertableProperty constructor that fails to type check, use the more powerful <!> operator
2015-10-19improve Info type using GADT, at nomeata's suggestionJoey Hess
This makes Show Info work, and simplifies the implementation.

2015-10-10tighten focus of Propellor module, adding Propellor.Base for all the exportsJoey Hess
2015-10-10Improved documentation, particularly of the Propellor module.Joey Hess
This involved some code changes, including some renaming of instance methods. (ABI change)
2015-09-30change HostContext for containersJoey Hess
Privdata that uses HostContext inside a container will now have the name of the container as its context, rather than the name of the host(s) where the container is used. This allows eg, having different passwords for a user in different containers. Note that previously, propellor would prompt using the container name as the context, but not actually use privdata using that context; so this is a bug fix. I don't entirely like the implementation; I had to put the code to change the context in PropAccum, and it's not generalized past PrivInfo.

2015-09-06Added Propellor.Property.Rsync. WIP; untestedJoey Hess
Convert Info to use Data.Dynamic, so properties can export and consume info of any type that is Typeable and a Monoid, including data types private to a module. (API change) Thanks to Joachim Breitner for the idea.
2015-01-25store PropList reversed to optimise &Joey Hess
PropList is now an opaque type, to prevent misuse. Note that the PropAccum Host instance cannot use reversed order.
2015-01-24GADT properties seem to work (untested)Joey Hess
* Property has been converted to a GADT, and will be Property NoInfo or Property HasInfo. This was done to make sure that ensureProperty is only used on properties that do not have Info. Transition guide: - Change all "Property" to "Property NoInfo" or "Property WithInfo" (The compiler can tell you if you got it wrong!) - To construct a RevertableProperty, it is useful to use the new (<!>) operator - Constructing a list of properties can be problimatic, since Property NoInto and Property WithInfo are different types and cannot appear in the same list. To deal with this, "props" has been added, and can built up a list of properties of different types, using the same (&) and (!) operators that are used to build up a host's properties.

2015-01-19rename HostLike to PropAccumJoey Hess
This is more general; it doesn't need to contain a Host. It would, for example, be possible to make Property itself be an instance of PropAccum.
