-- $usage
-- This module stores some user contributed themes which can be used
-- with decorated layouts (such as Tabbed). (Note that these themes
-- only apply to decorated layouts, such as those found in
-- "XMonad.Layout.Tabbed" and "XMonad.Layout.DecorationMadness"; they
-- do not apply to xmonad as a whole.)
--
-- If you want to use one of them with one of your decorated layouts,
-- you need to substitute defaultTheme with, for instance, (theme
-- smallClean).
--
-- Here is an example:
--
-- > import XMonad
-- > import XMonad.Util.Themes
-- > import XMonad.Layout.Tabbed
-- >
-- > myLayout = tabbed shrinkText (theme smallClean)
-- >
-- > main = xmonad defaultConfig {layoutHook = myLayout}
--
-- If you have a theme you would like to share, adding it to this
-- module is very easy.
--
-- You can use 'xmonadTheme' or 'smallClean' as a template.
--
-- At the present time only the 'themeName' field is used. But please
-- provide all the other information, which will be used at a later
-- time.
--
-- Please, remember to add your theme to the list of exported
-- functions, and to the 'listOfThemes'.
--
-- Thanks for your contribution!

Only certain blessed classes can be used in a deriving clause (without the

are listed below in the definition of hasStockDeriving. The sideConditions
function determines the criteria that needs to be met in order for a particular

A class might be able to be used in a deriving clause if -XDeriveAnyClass

Note [Deriving and unused record selectors]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Consider this (see Trac #13919):
module Main (main) where
data Foo = MkFoo {bar :: String} deriving Show
main :: IO ()
main = print (Foo "hello")
Strictly speaking, the record selector `bar` is unused in this module, since
neither `main` nor the derived `Show` instance for `Foo` mention `bar`.
However, the behavior of `main` is affected by the presence of `bar`, since
it will print different output depending on whether `MkFoo` is defined using
record selectors or not. Therefore, we do not to issue a
"Defined but not used: ‘bar’" warning for this module, since removing `bar`
changes the program's behavior. This is the reason behind the [Name] part of
the return type of `hasStockDeriving`—it tracks all of the record selector
`Name`s for which -Wunused-binds should be suppressed.
Currently, the only three stock derived classes that require this are Read,
Show, and Generic, as their derived code all depend on the record selectors
of the derived data type's constructors.
See also Note [Newtype deriving and unused constructors] in TcDeriv for
another example of a similar trick.

Note [Deriving any class]
~~~~~~~~~~~~~~~~~~~~~~~~~
Classic uses of a deriving clause, or a standalone-deriving declaration, are
for:
* a stock class like Eq or Show, for which GHC knows how to generate
the instance code
* a newtype, via the mechanism enabled by GeneralizedNewtypeDeriving
The DeriveAnyClass extension adds a third way to derive instances, based on
empty instance declarations.
The canonical use case is in combination with GHC.Generics and default method
signatures. These allow us to have instance declarations being empty, but still
useful, e.g.
data T a = ...blah..blah... deriving( Generic )
instance C a => C (T a) -- No 'where' clause
where C is some "random" user-defined class.
This boilerplate code can be replaced by the more compact
data T a = ...blah..blah... deriving( Generic, C )
if DeriveAnyClass is enabled.
This is not restricted to Generics; any class can be derived, simply giving
rise to an empty instance.
Unfortunately, it is not clear how to determine the context (when using a
deriving clause; in standalone deriving, the user provides the context).
GHC uses the same heuristic for figuring out the class context that it uses for
Eq in the case of *-kinded classes, and for Functor in the case of
* -> *-kinded classes. That may not be optimal or even wrong. But in such
cases, standalone deriving can still be used.
Note [Check that the type variable is truly universal]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For Functor and Traversable instances, we must check that the *last argument*
of the type constructor is used truly universally quantified. Example
data T a b where
T1 :: a -> b -> T a b -- Fine! Vanilla H-98
T2 :: b -> c -> T a b -- Fine! Existential c, but we can still map over 'b'
T3 :: b -> T Int b -- Fine! Constraint 'a', but 'b' is still polymorphic
T4 :: Ord b => b -> T a b -- No! 'b' is constrained
T5 :: b -> T b b -- No! 'b' is constrained
T6 :: T a (b,b) -- No! 'b' is constrained
Notice that only the first of these constructors is vanilla H-98. We only
need to take care about the last argument (b in this case). See Trac #8678.
Eg. for T1-T3 we can write
fmap f (T1 a b) = T1 a (f b)
fmap f (T2 b c) = T2 (f b) c
fmap f (T3 x) = T3 (f x)
We need not perform these checks for Foldable instances, however, since
functions in Foldable can only consume existentially quantified type variables,
rather than produce them (as is the case in Functor and Traversable functions.)
As a result, T can have a derived Foldable instance:
foldr f z (T1 a b) = f b z
foldr f z (T2 b c) = f b z
foldr f z (T3 x) = f x z
foldr f z (T4 x) = f x z
foldr f z (T5 x) = f x z
foldr _ z T6 = z
See Note [DeriveFoldable with ExistentialQuantification] in TcGenFunctor.
For Functor and Traversable, we must take care not to let type synonyms
unfairly reject a type for not being truly universally quantified. An
example of this is:
type C (a :: Constraint) b = a
data T a b = C (Show a) b => MkT b
Here, the existential context (C (Show a) b) does technically mention the last
type variable b. But this is OK, because expanding the type synonym C would
give us the context (Show a), which doesn't mention b. Therefore, we must make
sure to expand type synonyms before performing this check. Not doing so led to
Trac #13813.
