From 0ee04ecc43e047b00437fb660e71f7dd67dd3afc Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Sat, 24 Jan 2015 22:38:10 -0400 Subject: GADT properties seem to work (untested) * 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. --- src/Propellor/Property/SiteSpecific/GitHome.hs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/Propellor/Property/SiteSpecific/GitHome.hs') diff --git a/src/Propellor/Property/SiteSpecific/GitHome.hs b/src/Propellor/Property/SiteSpecific/GitHome.hs index 6ed02146..59e62d80 100644 --- a/src/Propellor/Property/SiteSpecific/GitHome.hs +++ b/src/Propellor/Property/SiteSpecific/GitHome.hs @@ -6,7 +6,7 @@ import Propellor.Property.User import Utility.SafeCommand -- | Clones Joey Hess's git home directory, and runs its fixups script. -installedFor :: UserName -> Property +installedFor :: UserName -> Property NoInfo installedFor user = check (not <$> hasGitDir user) $ property ("githome " ++ user) (go =<< liftIO (homedir user)) `requires` Apt.installed ["git"] -- cgit v1.2.3
