-- | A library for working with .cabal files

-- | Compatibility layer for <a>Control.Monad.Fail</a>
module Distribution.Compat.MonadFail

-- | When a value is bound in <tt>do</tt>-notation, the pattern on the left
--   hand side of <tt>&lt;-</tt> might not match. In this case, this class
--   provides a function to recover.
--   
--   A <a>Monad</a> without a <a>MonadFail</a> instance may only be used in
--   conjunction with pattern that always match, such as newtypes, tuples,
--   data types with only a single data constructor, and irrefutable
--   patterns (<tt>~pat</tt>).
--   
--   Instances of <a>MonadFail</a> should satisfy the following law:
--   <tt>fail s</tt> should be a left zero for <a>&gt;&gt;=</a>,
--   
--   <pre>
--   fail s &gt;&gt;= f  =  fail s
--   </pre>
--   
--   If your <a>Monad</a> is also <a>MonadPlus</a>, a popular definition is
--   
--   <pre>
--   fail _ = mzero
--   </pre>
--   
--   <tt>fail s</tt> should be an action that runs in the monad itself, not
--   an exception (except in instances of <tt>MonadIO</tt>). In particular,
--   <tt>fail</tt> should not be implemented in terms of <tt>error</tt>.

fail :: MonadFail m => String -> m a


-- | Per Conor McBride, the <a>Newtype</a> typeclass represents the packing

module Distribution.Compat.Newtype

-- | The <tt>FunctionalDependencies</tt> version of <a>Newtype</a>

--   
--   Since Cabal-3.0 class arguments are in a different order than in
--   <tt>newtype</tt> package. This change is to allow usage with
--   <tt>DeriveAnyClass</tt> (and <tt>DerivingStrategies</tt>, in GHC-8.2).

--   <pre>

--   Another approach would be to use <tt>TypeFamilies</tt> (and possibly
--   compute inner type using <a>GHC.Generics</a>), but we think
--   <tt>FunctionalDependencies</tt> version gives cleaner type signatures.

-- | This module does two things:
--   
--   <ul>
--   <li>Acts as a compatibility layer, like <tt>base-compat</tt>.</li>
--   <li>Provides commonly used imports.</li>
--   </ul>
module Distribution.Compat.Prelude

-- | A fixed-precision integer type with at least the range <tt>[-2^29 ..
--   2^29-1]</tt>. The exact range for a given implementation can be
--   determined by using <a>minBound</a> and <a>maxBound</a> from the
--   <a>Bounded</a> class.
data () => Int

-- | Single-precision floating point numbers. It is desirable that this
--   type be at least equal in range and precision to the IEEE
--   single-precision type.
data () => Float

-- | The character type <a>Char</a> is an enumeration whose values
--   represent Unicode (or equivalently ISO/IEC 10646) code points (i.e.
--   characters, see <a>http://www.unicode.org/</a> for details). This set
--   extends the ISO 8859-1 (Latin-1) character set (the first 256
--   characters), which is itself an extension of the ASCII character set
--   (the first 128 characters). A character literal in Haskell has type
--   <a>Char</a>.
--   
--   To convert a <a>Char</a> to or from the corresponding <a>Int</a> value
--   defined by Unicode, use <a>toEnum</a> and <a>fromEnum</a> from the
--   <a>Enum</a> class respectively (or equivalently <a>ord</a> and
--   <a>chr</a>).
data () => Char

-- | A value of type <tt><a>IO</a> a</tt> is a computation which, when
--   performed, does some I/O before returning a value of type <tt>a</tt>.
--   
--   There is really only one way to "perform" an I/O action: bind it to
--   <tt>Main.main</tt> in your program. When your program is run, the I/O
--   will be performed. It isn't possible to perform I/O from an arbitrary
--   function, unless that function is itself in the <a>IO</a> monad and
--   called at some point, directly or indirectly, from <tt>Main.main</tt>.
--   
--   <a>IO</a> is a monad, so <a>IO</a> actions can be combined using
--   either the do-notation or the <a>&gt;&gt;</a> and <a>&gt;&gt;=</a>
--   operations from the <a>Monad</a> class.
data () => IO a
data () => Bool
False :: Bool
True :: Bool

-- | Double-precision floating point numbers. It is desirable that this
--   type be at least equal in range and precision to the IEEE
--   double-precision type.
data () => Double
data () => Ordering
LT :: Ordering
EQ :: Ordering
GT :: Ordering

-- | The <a>Maybe</a> type encapsulates an optional value. A value of type
--   <tt><a>Maybe</a> a</tt> either contains a value of type <tt>a</tt>
--   (represented as <tt><a>Just</a> a</tt>), or it is empty (represented
--   as <a>Nothing</a>). Using <a>Maybe</a> is a good way to deal with
--   errors or exceptional cases without resorting to drastic measures such
--   as <a>error</a>.
--   
--   The <a>Maybe</a> type is also a monad. It is a simple kind of error
--   monad, where all errors are represented by <a>Nothing</a>. A richer
--   error monad can be built using the <a>Either</a> type.
data () => Maybe a
Nothing :: Maybe a
Just :: a -> Maybe a

-- | Lifted, homogeneous equality. By lifted, we mean that it can be bogus
--   (deferred type error). By homogeneous, the two types <tt>a</tt> and
--   <tt>b</tt> must have the same kinds.
class a ~# b => (a :: k) ~ (b :: k)

-- | Arbitrary precision integers. In contrast with fixed-size integral
--   types such as <a>Int</a>, the <a>Integer</a> type represents the
--   entire infinite range of integers.
--   
--   Integers are stored in a kind of sign-magnitude form, hence do not
--   expect two's complement form when using bit operations.
--   
--   If the value is small (fit into an <a>Int</a>), <a>IS</a> constructor
--   is used. Otherwise <a>Integer</a> and <a>IN</a> constructors are used
--   to store a <a>BigNat</a> representing respectively the positive or the
--   negative value magnitude.
--   
--   Invariant: <a>Integer</a> and <a>IN</a> are used iff value doesn't fit
--   in <a>IS</a>
data () => Integer

-- | The <a>Either</a> type represents values with two possibilities: a
--   value of type <tt><a>Either</a> a b</tt> is either <tt><a>Left</a>
--   a</tt> or <tt><a>Right</a> b</tt>.
--   
--   The <a>Either</a> type is sometimes used to represent a value which is
--   either correct or an error; by convention, the <a>Left</a> constructor
--   is used to hold an error value and the <a>Right</a> constructor is
--   used to hold a correct value (mnemonic: "right" also means "correct").
--   
--   <h4><b>Examples</b></h4>
--   
--   The type <tt><a>Either</a> <a>String</a> <a>Int</a></tt> is the type
--   of values which can be either a <a>String</a> or an <a>Int</a>. The
--   <a>Left</a> constructor can be used only on <a>String</a>s, and the
--   <a>Right</a> constructor can be used only on <a>Int</a>s:
--   
--   <pre>
--   &gt;&gt;&gt; let s = Left "foo" :: Either String Int
--   
--   &gt;&gt;&gt; s
--   Left "foo"
--   
--   &gt;&gt;&gt; let n = Right 3 :: Either String Int
--   
--   &gt;&gt;&gt; n
--   Right 3
--   
--   &gt;&gt;&gt; :type s
--   s :: Either String Int
--   
--   &gt;&gt;&gt; :type n
--   n :: Either String Int
--   </pre>
--   
--   The <a>fmap</a> from our <a>Functor</a> instance will ignore
--   <a>Left</a> values, but will apply the supplied function to values
--   contained in a <a>Right</a>:
--   
--   <pre>
--   &gt;&gt;&gt; let s = Left "foo" :: Either String Int
--   
--   &gt;&gt;&gt; let n = Right 3 :: Either String Int
--   
--   &gt;&gt;&gt; fmap (*2) s
--   Left "foo"
--   
--   &gt;&gt;&gt; fmap (*2) n
--   Right 6
--   </pre>
--   
--   The <a>Monad</a> instance for <a>Either</a> allows us to chain
--   together multiple actions which may fail, and fail overall if any of
--   the individual steps failed. First we'll write a function that can
--   either parse an <a>Int</a> from a <a>Char</a>, or fail.
--   
--   <pre>
--   &gt;&gt;&gt; import Data.Char ( digitToInt, isDigit )
--   
--   &gt;&gt;&gt; :{
--       let parseEither :: Char -&gt; Either String Int
--           parseEither c
--             | isDigit c = Right (digitToInt c)
--             | otherwise = Left "parse error"
--   
--   &gt;&gt;&gt; :}
--   </pre>
--   
--   The following should work, since both <tt>'1'</tt> and <tt>'2'</tt>
--   can be parsed as <a>Int</a>s.
--   
--   <pre>
--   &gt;&gt;&gt; :{
--       let parseMultiple :: Either String Int
--           parseMultiple = do
--             x &lt;- parseEither '1'
--             y &lt;- parseEither '2'
--             return (x + y)
--   
--   &gt;&gt;&gt; :}
--   </pre>
--   
--   <pre>
--   &gt;&gt;&gt; parseMultiple
--   Right 3
--   </pre>
--   
--   But the following should fail overall, since the first operation where
--   we attempt to parse <tt>'m'</tt> as an <a>Int</a> will fail:
--   
--   <pre>
--   &gt;&gt;&gt; :{
--       let parseMultiple :: Either String Int

--             return (x + y)
--   
--   &gt;&gt;&gt; :}

--   <a>readPrec</a>, on the other hand, is based on a much more efficient
--   <a>ReadPrec</a> datatype (a.k.a "new-style parsers"), but its
--   definition relies on the use of the <tt>RankNTypes</tt> language
--   extension. Therefore, <a>readPrec</a> (and its cousin,
--   <a>readListPrec</a>) are marked as GHC-only. Nevertheless, it is
--   recommended to use <a>readPrec</a> instead of <a>readsPrec</a>

--   
--   As mentioned above, derived <a>Read</a> instances in GHC will

--   will simply use <a>readPrec</a> under the hood. If you are writing a

--   <pre>
--   instance <a>Read</a> T where

--   Derived instances of <a>Show</a> have the following properties, which
--   are compatible with derived instances of <a>Read</a>:
--   
--   <ul>
--   <li>The result of <a>show</a> is a syntactically correct Haskell
--   expression containing only constants, given the fixity declarations in
--   force at the point where the type is declared. It contains only the
--   constructor names defined in the data type, parentheses, and spaces.
--   When labelled constructor fields are used, braces, commas, field
--   names, and equal signs are also used.</li>
--   <li>If the constructor is defined to be an infix operator, then
--   <a>showsPrec</a> will produce infix applications of the
--   constructor.</li>
--   <li>the representation will be enclosed in parentheses if the
--   precedence of the top-level constructor in <tt>x</tt> is less than
--   <tt>d</tt> (associativity is ignored). Thus, if <tt>d</tt> is
--   <tt>0</tt> then the result is never surrounded in parentheses; if
--   <tt>d</tt> is <tt>11</tt> it is always surrounded in parentheses,
--   unless it is an atomic expression.</li>
--   <li>If the constructor is defined using record syntax, then
--   <a>show</a> will produce the record-syntax form, with the fields given
--   in the same order as the original declaration.</li>
--   </ul>
--   
--   For example, given the declarations
--   
--   <pre>
--   infixr 5 :^:
--   data Tree a =  Leaf a  |  Tree a :^: Tree a
--   </pre>
--   
--   the derived instance of <a>Show</a> is equivalent to
--   
--   <pre>
--   instance (Show a) =&gt; Show (Tree a) where
--   
--          showsPrec d (Leaf m) = showParen (d &gt; app_prec) $
--               showString "Leaf " . showsPrec (app_prec+1) m
--            where app_prec = 10
--   
--          showsPrec d (u :^: v) = showParen (d &gt; up_prec) $
--               showsPrec (up_prec+1) u .

--               showsPrec (up_prec+1) v
--            where up_prec = 5
--   </pre>
--   
--   Note that right-associativity of <tt>:^:</tt> is ignored. For example,
--   
--   <ul>
--   <li><tt><a>show</a> (Leaf 1 :^: Leaf 2 :^: Leaf 3)</tt> produces the
--   string <tt>"Leaf 1 :^: (Leaf 2 :^: Leaf 3)"</tt>.</li>

--   
--   Some type constructors with two parameters or more have a

--   
--   It may seem surprising that the function is only applied to the last

--   <tt>fmap</tt>).
--   
--   It explains why <tt>fmap</tt> can be used with tuples containing
--   values of different types as in the following example:

-- | Left-associative fold of a structure, lazy in the accumulator. This is
--   rarely what you want, but can work well for structures with efficient
--   right-to-left sequencing and an operator that is lazy in its left
--   argument.
--   
--   In the case of lists, <a>foldl</a>, when applied to a binary operator,
--   a starting value (typically the left-identity of the operator), and a
--   list, reduces the list using the binary operator, from left to right:
--   
--   <pre>
--   foldl f z [x1, x2, ..., xn] == (...((z `f` x1) `f` x2) `f`...) `f` xn
--   </pre>
--   
--   Note that to produce the outermost application of the operator the
--   entire input list must be traversed. Like all left-associative folds,
--   <a>foldl</a> will diverge if given an infinite list.
--   
--   If you want an efficient strict left-fold, you probably want to use
--   <a>foldl'</a> instead of <a>foldl</a>. The reason for this is that the
--   latter does not force the <i>inner</i> results (e.g. <tt>z `f` x1</tt>
--   in the above example) before applying them to the operator (e.g. to
--   <tt>(`f` x2)</tt>). This results in a thunk chain <i>O(n)</i> elements
--   long, which then must be evaluated from the outside-in.
--   
--   For a general <a>Foldable</a> structure this should be semantically
--   identical to:
--   
--   <pre>
--   foldl f z = <a>foldl</a> f z . <a>toList</a>
--   </pre>
--   
--   <h4><b>Examples</b></h4>
--   
--   The first example is a strict fold, which in practice is best
--   performed with <a>foldl'</a>.
--   
--   <pre>
--   &gt;&gt;&gt; foldl (+) 42 [1,2,3,4]
--   52
--   </pre>
--   
--   Though the result below is lazy, the input is reversed before
--   prepending it to the initial accumulator, so corecursion begins only
--   after traversing the entire input string.
--   
--   <pre>
--   &gt;&gt;&gt; foldl (\acc c -&gt; c : acc) "abcd" "efgh"
--   "hgfeabcd"
--   </pre>
--   
--   A left fold of a structure that is infinite on the right cannot
--   terminate, even when for any finite input the fold just returns the
--   initial accumulator:
--   
--   <pre>
--   &gt;&gt;&gt; foldl (\a _ -&gt; a) 0 $ repeat 1
--   * Hangs forever *

-- | The <a>Data</a> class comprehends a fundamental primitive
--   <a>gfoldl</a> for folding over constructor applications, say terms.
--   This primitive can be instantiated in several ways to map over the
--   immediate subterms of a term; see the <tt>gmap</tt> combinators later
--   in this class. Indeed, a generic programmer does not necessarily need
--   to use the ingenious gfoldl primitive but rather the intuitive
--   <tt>gmap</tt> combinators. The <a>gfoldl</a> primitive is completed by
--   means to query top-level constructors, to turn constructor
--   representations into proper terms, and to list all possible datatype
--   constructors. This completion allows us to serve generic programming
--   scenarios like read, show, equality, term generation.
--   
--   The combinators <a>gmapT</a>, <a>gmapQ</a>, <a>gmapM</a>, etc are all
--   provided with default definitions in terms of <a>gfoldl</a>, leaving
--   open the opportunity to provide datatype-specific definitions. (The
--   inclusion of the <tt>gmap</tt> combinators as members of class
--   <a>Data</a> allows the programmer or the compiler to derive
--   specialised, and maybe more efficient code per datatype. <i>Note</i>:
--   <a>gfoldl</a> is more higher-order than the <tt>gmap</tt> combinators.
--   This is subject to ongoing benchmarking experiments. It might turn out
--   that the <tt>gmap</tt> combinators will be moved out of the class
--   <a>Data</a>.)
--   
--   Conceptually, the definition of the <tt>gmap</tt> combinators in terms
--   of the primitive <a>gfoldl</a> requires the identification of the
--   <a>gfoldl</a> function arguments. Technically, we also need to
--   identify the type constructor <tt>c</tt> for the construction of the
--   result type from the folded term type.
--   
--   In the definition of <tt>gmapQ</tt><i>x</i> combinators, we use
--   phantom type constructors for the <tt>c</tt> in the type of
--   <a>gfoldl</a> because the result type of a query does not involve the
--   (polymorphic) type of the term argument. In the definition of
--   <a>gmapQl</a> we simply use the plain constant type constructor
--   because <a>gfoldl</a> is left-associative anyway and so it is readily
--   suited to fold a left-associative binary operation over the immediate
--   subterms. In the definition of gmapQr, extra effort is needed. We use
--   a higher-order accumulation trick to mediate between left-associative
--   constructor application vs. right-associative binary operation (e.g.,
--   <tt>(:)</tt>). When the query is meant to compute a value of type
--   <tt>r</tt>, then the result type within generic folding is <tt>r -&gt;
--   r</tt>. So the result of folding is a function to which we finally
--   pass the right unit.
--   
--   With the <tt>-XDeriveDataTypeable</tt> option, GHC can generate
--   instances of the <a>Data</a> class automatically. For example, given
--   the declaration
--   
--   <pre>
--   data T a b = C1 a b | C2 deriving (Typeable, Data)
--   </pre>
--   
--   GHC will generate an instance that is equivalent to
--   
--   <pre>
--   instance (Data a, Data b) =&gt; Data (T a b) where
--       gfoldl k z (C1 a b) = z C1 `k` a `k` b
--       gfoldl k z C2       = z C2
--   
--       gunfold k z c = case constrIndex c of
--                           1 -&gt; k (k (z C1))
--                           2 -&gt; z C2

-- | Right-associative fold of a structure, lazy in the accumulator.
--   
--   In the case of lists, <a>foldr</a>, when applied to a binary operator,
--   a starting value (typically the right-identity of the operator), and a
--   list, reduces the list using the binary operator, from right to left:

--   <pre>
--   foldr f z [x1, x2, ..., xn] == x1 `f` (x2 `f` ... (xn `f` z)...)

--   application of the operator to the first element of the list, given an
--   operator lazy in its right argument, <a>foldr</a> can produce a
--   terminating expression from an unbounded list.
--   
--   For a general <a>Foldable</a> structure this should be semantically

--   
--   It may still terminate under one of the following conditions:
--   
--   <ul>
--   <li>the folding function is short-circuiting</li>
--   <li>the folding function is lazy on its second argument</li>
--   </ul>
--   
--   <h6>Short-circuiting</h6>
--   
--   <tt>(<a>||</a>)</tt> short-circuits on <a>True</a> values, so the
--   following terminates because there is a <a>True</a> value finitely far
--   from the left side:
--   
--   <pre>
--   &gt;&gt;&gt; foldr (||) False (True : repeat False)
--   True
--   </pre>
--   
--   But the following doesn't terminate:
--   
--   <pre>
--   &gt;&gt;&gt; foldr (||) False (repeat False ++ [True])
--   * Hangs forever *
--   </pre>
--   
--   <h6>Laziness in the second argument</h6>
--   
--   Applying <a>foldr</a> to infinite structures terminates when the
--   operator is lazy in its second argument (the initial accumulator is
--   never used in this case, and so could be left <a>undefined</a>, but
--   <tt>[]</tt> is more clear):
--   
--   <pre>
--   &gt;&gt;&gt; take 5 $ foldr (\i acc -&gt; i : fmap (+3) acc) [] (repeat 1)
--   [1,4,7,10,13]
--   </pre>
foldr :: Foldable t => (a -> b -> b) -> b -> t a -> b

-- | Test whether the structure is empty. The default implementation is
--   Left-associative and lazy in both the initial element and the
--   accumulator. Thus optimised for structures where the first element can
--   be accessed in constant time. Structures where this is not the case
--   should have a non-default implementation.
--   
--   <h4><b>Examples</b></h4>

--   
--   <pre>
--   &gt;&gt;&gt; null [1]
--   False
--   </pre>
--   
--   <a>null</a> is expected to terminate even for infinite structures. The
--   default implementation terminates provided the structure is bounded on
--   the left (there is a leftmost element).

null :: Foldable t => t a -> Bool

guard :: Alternative f => Bool -> f ()

-- | This is the simplest of the exception-catching functions. It takes a

--   Otherwise, the result is returned as normal. For example:
--   
--   <pre>
--   catch (readFile f)
--         (\e -&gt; do let err = show (e :: IOException)
--                   hPutStr stderr ("Warning: Couldn't open " ++ f ++ ": " ++ err)

--   </pre>
--   
--   Note that we have to give a type signature to <tt>e</tt>, or the

--   possible to catch exceptions of any type, see the section "Catching
--   all exceptions" (in <a>Control.Exception</a>) for an explanation of
--   the problems with doing so.
--   
--   For catching exceptions in pure (non-<a>IO</a>) expressions, see the
--   function <a>evaluate</a>.
--   
--   Note that due to Haskell's unspecified evaluation order, an expression
--   may throw one of several possible exceptions: consider the expression
--   <tt>(error "urk") + (1 `div` 0)</tt>. Does the expression throw
--   <tt>ErrorCall "urk"</tt>, or <tt>DivideByZero</tt>?
--   
--   The answer is "it might throw either"; the choice is
--   non-deterministic. If you are catching any type of exception then you
--   might catch either. If you are calling <tt>catch</tt> with type <tt>IO
--   Int -&gt; (ArithException -&gt; IO Int) -&gt; IO Int</tt> then the
--   handler may get run with <tt>DivideByZero</tt> as an argument, or an
--   <tt>ErrorCall "urk"</tt> exception may be propagated further up. If
--   you call it again, you might get the opposite behaviour. This is ok,
--   because <a>catch</a> is an <a>IO</a> computation.
catch :: Exception e => IO a -> (e -> IO a) -> IO a

-- | A variant of <a>throw</a> that can only be used within the <a>IO</a>
--   monad.
--   
--   Although <a>throwIO</a> has a type that is an instance of the type of
--   <a>throw</a>, the two functions are subtly different:
--   
--   <pre>
--   throw e   `seq` ()  ===&gt; throw e
--   throwIO e `seq` ()  ===&gt; ()
--   </pre>
--   
--   The first example will cause the exception <tt>e</tt> to be raised,
--   whereas the second one won't. In fact, <a>throwIO</a> will only cause
--   an exception to be raised when it is used within the <a>IO</a> monad.
--   
--   The <a>throwIO</a> variant should be used in preference to
--   <a>throw</a> to raise an exception within the <a>IO</a> monad because
--   it guarantees ordering with respect to other operations, whereas
--   <a>throw</a> does not. We say that <a>throwIO</a> throws *precise*
--   exceptions and <a>throw</a>, <a>error</a>, etc. all throw *imprecise*
--   exceptions. For example
--   
--   <pre>
--   throw e + error "boom" ===&gt; error "boom"
--   throw e + error "boom" ===&gt; throw e
--   </pre>
--   
--   are both valid reductions and the compiler may pick any (loop, even),
--   whereas
--   
--   <pre>
--   throwIO e &gt;&gt; error "boom" ===&gt; throwIO e
--   </pre>
--   
--   will always throw <tt>e</tt> when executed.
--   
--   See also the <a>GHC wiki page on precise exceptions</a> for a more
--   technical introduction to how GHC optimises around precise vs.
--   imprecise exceptions.
throwIO :: Exception e => e -> IO a

-- | Evaluate the argument to weak head normal form.
--   
--   <a>evaluate</a> is typically used to uncover any exceptions that a
--   lazy value may contain, and possibly handle them.
--   
--   <a>evaluate</a> only evaluates to <i>weak head normal form</i>. If
--   deeper evaluation is needed, the <tt>force</tt> function from
--   <tt>Control.DeepSeq</tt> may be handy:
--   
--   <pre>
--   evaluate $ force x
--   </pre>
--   
--   There is a subtle difference between <tt><a>evaluate</a> x</tt> and
--   <tt><a>return</a> <a>$!</a> x</tt>, analogous to the difference
--   between <a>throwIO</a> and <a>throw</a>. If the lazy value <tt>x</tt>
--   throws an exception, <tt><a>return</a> <a>$!</a> x</tt> will fail to
--   return an <a>IO</a> action and will throw an exception instead.
--   <tt><a>evaluate</a> x</tt>, on the other hand, always produces an
--   <a>IO</a> action; that action will throw an exception upon
--   <i>execution</i> iff <tt>x</tt> throws an exception upon
--   <i>evaluation</i>.
--   
--   The practical implication of this difference is that due to the
--   <i>imprecise exceptions</i> semantics,
--   
--   <pre>
--   (return $! error "foo") &gt;&gt; error "bar"
--   </pre>
--   
--   may throw either <tt>"foo"</tt> or <tt>"bar"</tt>, depending on the
--   optimizations performed by the compiler. On the other hand,
--   
--   <pre>
--   evaluate (error "foo") &gt;&gt; error "bar"
--   </pre>
--   
--   is guaranteed to throw <tt>"foo"</tt>.
--   
--   The rule of thumb is to use <a>evaluate</a> to force or handle
--   exceptions in lazy values. If, on the other hand, you are forcing a
--   lazy value for efficiency reasons only and do not care about
--   exceptions, you may use <tt><a>return</a> <a>$!</a> x</tt>.
evaluate :: a -> IO a

-- | Any type that you wish to throw or catch as an exception must be an
--   instance of the <tt>Exception</tt> class. The simplest case is a new
--   exception type directly below the root:
--   
--   <pre>
--   data MyException = ThisException | ThatException
--       deriving Show
--   
--   instance Exception MyException
--   </pre>
--   
--   The default method definitions in the <tt>Exception</tt> class do what
--   we need in this case. You can now throw and catch
--   <tt>ThisException</tt> and <tt>ThatException</tt> as exceptions:
--   
--   <pre>
--   *Main&gt; throw ThisException `catch` \e -&gt; putStrLn ("Caught " ++ show (e :: MyException))
--   Caught ThisException
--   </pre>
--   
--   In more complicated examples, you may wish to define a whole hierarchy
--   of exceptions:
--   
--   <pre>
--   ---------------------------------------------------------------------
--   -- Make the root exception type for all the exceptions in a compiler
--   
--   data SomeCompilerException = forall e . Exception e =&gt; SomeCompilerException e
--   
--   instance Show SomeCompilerException where
--       show (SomeCompilerException e) = show e
--   
--   instance Exception SomeCompilerException
--   
--   compilerExceptionToException :: Exception e =&gt; e -&gt; SomeException
--   compilerExceptionToException = toException . SomeCompilerException
--   
--   compilerExceptionFromException :: Exception e =&gt; SomeException -&gt; Maybe e
--   compilerExceptionFromException x = do
--       SomeCompilerException a &lt;- fromException x
--       cast a
--   
--   ---------------------------------------------------------------------
--   -- Make a subhierarchy for exceptions in the frontend of the compiler
--   
--   data SomeFrontendException = forall e . Exception e =&gt; SomeFrontendException e
--   
--   instance Show SomeFrontendException where
--       show (SomeFrontendException e) = show e
--   
--   instance Exception SomeFrontendException where
--       toException = compilerExceptionToException
--       fromException = compilerExceptionFromException
--   
--   frontendExceptionToException :: Exception e =&gt; e -&gt; SomeException
--   frontendExceptionToException = toException . SomeFrontendException
--   
--   frontendExceptionFromException :: Exception e =&gt; SomeException -&gt; Maybe e
--   frontendExceptionFromException x = do
--       SomeFrontendException a &lt;- fromException x
--       cast a
--   
--   ---------------------------------------------------------------------
--   -- Make an exception type for a particular frontend compiler exception
--   
--   data MismatchedParentheses = MismatchedParentheses
--       deriving Show
--   
--   instance Exception MismatchedParentheses where
--       toException   = frontendExceptionToException
--       fromException = frontendExceptionFromException
--   </pre>
--   
--   We can now catch a <tt>MismatchedParentheses</tt> exception as
--   <tt>MismatchedParentheses</tt>, <tt>SomeFrontendException</tt> or
--   <tt>SomeCompilerException</tt>, but not other types, e.g.
--   <tt>IOException</tt>:
--   
--   <pre>
--   *Main&gt; throw MismatchedParentheses `catch` \e -&gt; putStrLn ("Caught " ++ show (e :: MismatchedParentheses))
--   Caught MismatchedParentheses
--   *Main&gt; throw MismatchedParentheses `catch` \e -&gt; putStrLn ("Caught " ++ show (e :: SomeFrontendException))
--   Caught MismatchedParentheses
--   *Main&gt; throw MismatchedParentheses `catch` \e -&gt; putStrLn ("Caught " ++ show (e :: SomeCompilerException))
--   Caught MismatchedParentheses
--   *Main&gt; throw MismatchedParentheses `catch` \e -&gt; putStrLn ("Caught " ++ show (e :: IOException))
--   *** Exception: MismatchedParentheses

-- | <a>deepseq</a>: fully evaluates the first argument, before returning
--   the second.
--   
--   The name <a>deepseq</a> is used to illustrate the relationship to
--   <a>seq</a>: where <a>seq</a> is shallow in the sense that it only
--   evaluates the top level of its argument, <a>deepseq</a> traverses the
--   entire data structure evaluating it completely.
--   
--   <a>deepseq</a> can be useful for forcing pending exceptions,
--   eradicating space leaks, or forcing lazy I/O to happen. It is also
--   useful in conjunction with parallel Strategies (see the
--   <tt>parallel</tt> package).
--   
--   There is no guarantee about the ordering of evaluation. The
--   implementation may evaluate the components of the structure in any
--   order or in parallel. To impose an actual order on evaluation, use
--   <tt>pseq</tt> from <a>Control.Parallel</a> in the <tt>parallel</tt>
--   package.

--   <pre>
--   force x = x `deepseq` x
--   </pre>
--   
--   <tt>force x</tt> fully evaluates <tt>x</tt>, and then returns it. Note
--   that <tt>force x</tt> only performs evaluation when the value of
--   <tt>force x</tt> itself is demanded, so essentially it turns shallow
--   evaluation into deep evaluation.
--   
--   <a>force</a> can be conveniently used in combination with
--   <tt>ViewPatterns</tt>:
--   
--   <pre>
--   {-# LANGUAGE BangPatterns, ViewPatterns #-}
--   import Control.DeepSeq
--   
--   someFun :: ComplexData -&gt; SomeResult
--   someFun (force -&gt; !arg) = {- 'arg' will be fully evaluated -}
--   </pre>
--   
--   Another useful application is to combine <a>force</a> with
--   <a>evaluate</a> in order to force deep evaluation relative to other
--   <a>IO</a> operations:
--   
--   <pre>
--   import Control.Exception (evaluate)
--   import Control.DeepSeq
--   
--   main = do
--     result &lt;- evaluate $ force $ pureComputation
--     {- 'result' will be fully evaluated at this point -}
--     return ()

--   
--   Finally, here's an exception safe variant of the <tt>readFile'</tt>
--   example:
--   
--   <pre>
--   readFile' :: FilePath -&gt; IO String
--   readFile' fn = bracket (openFile fn ReadMode) hClose $ \h -&gt;

--   
--   See <a>isUpperCase</a> for a more intuitive predicate. Note that

isAlpha :: Char -> Bool

-- | Selects alphabetic or numeric Unicode characters.

module Distribution.Types.CondTree

-- | A <a>CondTree</a> is used to represent the conditional structure of a
--   Cabal file, reflecting a syntax element subject to constraints, and
--   then any number of sub-elements which may be enabled subject to some
--   condition. Both <tt>a</tt> and <tt>c</tt> are usually <a>Monoid</a>s.
--   
--   To be more concrete, consider the following fragment of a
--   <tt>Cabal</tt> file:
--   
--   <pre>
--   build-depends: base &gt;= 4.0
--   if flag(extra)
--       build-depends: base &gt;= 4.2
--   </pre>
--   
--   One way to represent this is to have <tt><a>CondTree</a>
--   <tt>ConfVar</tt> [<tt>Dependency</tt>] <tt>BuildInfo</tt></tt>. Here,
--   <a>condTreeData</a> represents the actual fields which are not behind
--   any conditional, while <a>condTreeComponents</a> recursively records
--   any further fields which are behind a conditional.
--   <a>condTreeConstraints</a> records the constraints (in this case,
--   <tt>base &gt;= 4.0</tt>) which would be applied if you use this
--   syntax; in general, this is derived off of <tt>targetBuildInfo</tt>
--   (perhaps a good refactoring would be to convert this into an opaque
--   type, with a smart constructor that pre-computes the dependencies.)

-- | This module implements a view of a <a>VersionRange</a> as a finite
--   list of separated version intervals and provides the Boolean algebra
--   operations union, intersection, and complement.
--   
--   It interprets the caret operator <tt>^&gt;=x.y</tt> as simply
--   <tt>==x.y.*</tt>. Until <tt>Cabal &lt; 3.6</tt>, this module was
--   called <a>Distribution.Types.VersionInterval</a>. The current module
--   <a>Distribution.Types.VersionInterval</a> (refurbished since <tt>Cabal
--   &gt;= 3.6</tt>) makes some effort to preserve the caret operator, but
--   so far does not expose the Boolean algebra structure.
module Distribution.Types.VersionInterval.Legacy

-- | A complementary representation of a <a>VersionRange</a>, using an
--   increasing sequence of separated (i.e., non-overlapping, non-touching)
--   non-empty intervals. The represented range is the union of these
--   intervals, meaning that the empty sequence denotes the empty range.
--   
--   As ranges form a Boolean algebra, we can compute union, intersection,
--   and complement. These operations are all linear in the size of the
--   input, thanks to the ordered representation.
--   
--   The interval-sequence representation gives a canonical representation
--   for the semantics of <a>VersionRange</a>s. This makes it easier to
--   check things like whether a version range is empty, covers all
--   versions, or requires a certain minimum or maximum version. It also
--   makes it easy to check equality (just <a>==</a>) or containment. It
--   also makes it easier to identify 'simple' version predicates for
--   translation into foreign packaging systems that do not support complex
--   version range expressions.

-- | Convert a <a>VersionRange</a> to a sequence of version intervals.
toVersionIntervals :: VersionRange -> VersionIntervals

-- | Convert a <a>VersionIntervals</a> value back into a

fromVersionIntervals :: VersionIntervals -> VersionRange

-- | Test if a version falls within the version intervals.

unionVersionIntervals :: VersionIntervals -> VersionIntervals -> VersionIntervals

-- | The intersection &lt;math&gt; of two interval sequences &lt;math&gt;
--   and &lt;math&gt; of lengths &lt;math&gt; and &lt;math&gt;, resp.,
--   satisfies the specification &lt;math&gt;. Thanks to the ordered
--   representation of intervals it can be computed in &lt;math&gt; (rather

relaxLastInterval :: VersionIntervals -> VersionIntervals

-- | Remove the first lower bound (i.e, make it &lt;math&gt;. Empty ranges
--   stay empty. &lt;math&gt;.
relaxHeadInterval :: VersionIntervals -> VersionIntervals

-- | View a <a>VersionRange</a> as a sequence of separated intervals.
--   
--   This provides a canonical view of the semantics of a
--   <a>VersionRange</a> as opposed to the syntax of the expression used to
--   define it. For the syntactic view use <tt>foldVersionRange</tt>.
--   
--   <i>Canonical</i> means that two semantically equal ranges translate to
--   the <i>same</i> <tt>[<a>VersionInterval</a>]</tt>, thus its <a>Eq</a>
--   instance can decide semantical equality of ranges.
--   
--   In the returned sequence, each interval is non-empty. The sequence is
--   in increasing order and the intervals are separated, i.e., they
--   neither overlap nor touch. Therefore only the first and last interval
--   can be unbounded. The sequence can be empty if the range is empty
--   (e.g. a range expression like <tt>&gt; 2 &amp;&amp; &lt; 1</tt>).
--   
--   Other checks are trivial to implement using this view. For example:
--   
--   <pre>
--   isNoVersion vr | [] &lt;- asVersionIntervals vr = True
--                  | otherwise                   = False

--   release. The <tt>ReopKind</tt> specifies which one we mean (or another
--   custom one).
--   
--   A package can specify one or the other kind or both. Most will specify
--   just a head repo but some may want to specify a repo to reconstruct
--   the sources for this package release.
--   
--   The required information is the <a>RepoType</a> which tells us if it's
--   using <a>Darcs</a>, <a>Git</a> for example. The <a>repoLocation</a>
--   and other details are interpreted according to the repo type.
data SourceRepo
SourceRepo :: RepoKind -> Maybe RepoType -> Maybe String -> Maybe String -> Maybe String -> Maybe String -> Maybe FilePath -> SourceRepo

[repoLocation] :: SourceRepo -> Maybe String

-- | <a>CVS</a> can put multiple "modules" on one server and requires a

--   <a>RepoType</a> and should not be given otherwise.
[repoModule] :: SourceRepo -> Maybe String

-- | The name or identifier of the branch, if any. Many source control
--   systems have the notion of multiple branches in a repo that exist in
--   the same location. For example <a>Git</a> and <a>CVS</a> use this
--   while systems like <a>Darcs</a> use different locations for different
--   branches. This field is optional but should be used if necessary to
--   identify the sources, especially for the <a>RepoThis</a> repo kind.
[repoBranch] :: SourceRepo -> Maybe String

-- | The tag identify a particular state of the repository. This should be
--   given for the <a>RepoThis</a> repo kind and not for <a>RepoHead</a>
--   kind.
[repoTag] :: SourceRepo -> Maybe String

-- | Some repositories contain multiple projects in different
--   subdirectories This field specifies the subdirectory where this
--   packages sources can be found, eg the subdirectory containing the
--   <tt>.cabal</tt> file. It is interpreted relative to the root of the
--   repository. This field is optional. If not given the default is "." ie
--   no subdirectory.
[repoSubdir] :: SourceRepo -> Maybe FilePath

-- | What this repo info is for, what it represents.
data RepoKind

-- | The repository for the "head" or development version of the project.
--   This repo is where we should track the latest development activity or
--   the usual repo people should get to contribute patches.

-- | Cabal often needs to do slightly different things on specific

--   very inconvenient because it is a string and different Haskell
--   implementations do not agree on using the same strings for the same
--   platforms! (In particular see the controversy over "windows" vs
--   "mingw32"). So to make it more consistent and easy to use we have an
--   <a>OS</a> enumeration.

--

-- | How strict to be when classifying strings into the <a>OS</a> and

--   
--   The reason we have multiple ways to do the classification is because
--   there are two situations where we need to do it.
--   
--   For parsing OS and arch names in .cabal files we really want everyone
--   to be referring to the same or arch by the same name. Variety is not a
--   virtue in this case. We don't mind about case though.
--   
--   For the System.Info.os/arch different Haskell implementations use
--   different names for the same or/arch. Also they tend to distinguish
--   versions of an OS/arch which we just don't care about.
--   
--   The <a>Compat</a> classification allows us to recognise aliases that
--   are already in common use but it allows us to distinguish them from
--   the canonical name which enables us to warn about such deprecated
--   aliases.

-- | A data type representing directed graphs, backed by <a>Data.Graph</a>.
--   It is strict in the node type.
--   
--   This is an alternative interface to <a>Data.Graph</a>. In this
--   interface, nodes (identified by the <a>IsNode</a> type class) are
--   associated with a key and record the keys of their neighbors. This
--   interface is more convenient than <a>Graph</a>, which requires
--   vertices to be explicitly handled by integer indexes.
--   
--   The current implementation has somewhat peculiar performance
--   characteristics. The asymptotics of all map-like operations mirror
--   their counterparts in <a>Data.Map</a>. However, to perform a graph
--   operation, we first must build the <a>Data.Graph</a> representation,
--   an operation that takes <i>O(V + E log V)</i>. However, this operation
--   can be amortized across all queries on that particular graph.
--   
--   Some nodes may be broken, i.e., refer to neighbors which are not
--   stored in the graph. In our graph algorithms, we transparently ignore
--   such edges; however, you can easily query for the broken vertices of a
--   graph using <a>broken</a> (and should, e.g., to ensure that a closure
--   of a graph is well-formed.) It's possible to take a closed subset of a
--   broken graph and get a well-formed graph.

-- | A complementary representation of a <a>VersionRange</a>. Instead of a

module Distribution.Types.UnitId

-- | A unit identifier identifies a (possibly instantiated)
--   package/component that can be installed the installed package
--   database. There are several types of components that can be installed:
--   
--   <ul>
--   <li>A traditional library with no holes, so that <tt>unitIdHash</tt>
--   is <tt>Nothing</tt>. In the absence of Backpack, <a>UnitId</a> is the
--   same as a <a>ComponentId</a>.</li>
--   <li>An indefinite, Backpack library with holes. In this case,
--   <tt>unitIdHash</tt> is still <tt>Nothing</tt>, but in the install,
--   there are only interfaces, no compiled objects.</li>
--   <li>An instantiated Backpack library with all the holes filled in.
--   <tt>unitIdHash</tt> is a <tt>Just</tt> a hash of the instantiating
--   mapping.</li>
--   </ul>
--   
--   A unit is a component plus the additional information on how the holes
--   are filled in. Thus there is a one to many relationship: for a
--   particular component there are many different ways of filling in the
--   holes, and each different combination is a unit (and has a separate
--   <a>UnitId</a>).
--   
--   <a>UnitId</a> is distinct from <tt>OpenUnitId</tt>, in that it is
--   always installed, whereas <tt>OpenUnitId</tt> are intermediate unit
--   identities that arise during mixin linking, and don't necessarily
--   correspond to any actually installed unit. Since the mapping is not
--   actually recorded in a <a>UnitId</a>, you can't actually substitute
--   over them (but you can substitute over <tt>OpenUnitId</tt>). See also
--   <a>Distribution.Backpack.FullUnitId</a> for a mechanism for expanding
--   an instantiated <a>UnitId</a> to retrieve its mapping.
--   
--   Backwards compatibility note: if you need to get the string
--   representation of a UnitId to pass, e.g., as a <tt>-package-id</tt>
--   flag, use the <tt>display</tt> function, which will work on all
--   versions of Cabal.

module Distribution.Types.Module

-- | This module defines the core data types for Backpack. For more
--   details, see:
--   
--   
--   <a>https://github.com/ezyang/ghc-proposals/blob/backpack/proposals/0000-backpack.rst</a>
module Distribution.Backpack

-- | An <a>OpenUnitId</a> describes a (possibly partially) instantiated
--   Backpack component, with a description of how the holes are filled in.
--   Unlike <a>OpenUnitId</a>, the <tt>ModuleSubst</tt> is kept in a
--   structured form that allows for substitution (which fills in holes.)
--   This form of unit cannot be installed. It must first be converted to a
--   <a>UnitId</a>.
--   
--   In the absence of Backpack, there are no holes to fill, so any such
--   component always has an empty module substitution; thus we can lossily
--   represent it as a 'DefiniteUnitId uid'.
--   
--   For a source component using Backpack, however, there is more
--   structure as components may be parametrized over some signatures, and
--   these "holes" may be partially or wholly filled.
--   
--   OpenUnitId plays an important role when we are mix-in linking, and is
--   recorded to the installed packaged database for indefinite packages;
--   however, for compiled packages that are fully instantiated, we
--   instantiate <a>OpenUnitId</a> into <a>UnitId</a>.
--   
--   For more details see the Backpack spec
--   <a>https://github.com/ezyang/ghc-proposals/blob/backpack/proposals/0000-backpack.rst</a>

module Distribution.Types.HookedBuildInfo

-- | <a>HookedBuildInfo</a> is mechanism that hooks can use to override the
--   <a>BuildInfo</a>s inside packages. One example use-case (which is used
--   in core libraries today) is as a way of passing flags which are
--   computed by a configure script into Cabal. In this case, the autoconf
--   build type adds hooks to read in a textual <a>HookedBuildInfo</a>
--   format prior to doing any operations.
--   
--   Quite honestly, this mechanism is a massive hack since we shouldn't be
--   editing the <tt>PackageDescription</tt> data structure (it's easy to
--   assume that this data structure shouldn't change and run into bugs,
--   see for example 1c20a6328579af9e37677d507e2e9836ef70ab9d). But it's a
--   bit convenient, because there isn't another data structure that allows
--   adding extra <a>BuildInfo</a> style things.
--   
--   In any case, a lot of care has to be taken to make sure the
--   <a>HookedBuildInfo</a> is applied to the <tt>PackageDescription</tt>.
--   In general this process occurs in <a>Distribution.Simple</a>, which is
--   responsible for orchestrating the hooks mechanism. The general
--   strategy:
--   
--   <ol>
--   <li>We run the pre-hook, which produces a <a>HookedBuildInfo</a>
--   (e.g., in the Autoconf case, it reads it out from a file).</li>
--   <li>We sanity-check the hooked build info with
--   <tt>sanityCheckHookedBuildInfo</tt>.</li>
--   <li>We update our <tt>PackageDescription</tt> (either freshly read or
--   cached from <tt>LocalBuildInfo</tt>) with
--   <tt>updatePackageDescription</tt>.</li>
--   </ol>
--   
--   In principle, we are also supposed to update the copy of the
--   <tt>PackageDescription</tt> stored in <tt>LocalBuildInfo</tt> at
--   <tt>localPkgDescr</tt>. Unfortunately, in practice, there are lots of
--   Custom setup scripts which fail to update <tt>localPkgDescr</tt> so
--   you really shouldn't rely on it. It's not DEPRECATED because there are
--   legitimate uses for it, but... yeah. Sharp knife. See
--   <a>https://github.com/haskell/cabal/issues/3606</a> for more
--   information on the issue.
--   
--   It is not well-specified whether or not a <a>HookedBuildInfo</a>
--   applied at configure time is persistent to the
--   <tt>LocalBuildInfo</tt>. The fact that <a>HookedBuildInfo</a> is
--   passed to <tt>confHook</tt> MIGHT SUGGEST that the
--   <a>HookedBuildInfo</a> is applied at this time, but actually since
--   9317b67e6122ab14e53f81b573bd0ecb388eca5a it has been ONLY used to
--   create a modified package description that we check for problems: it
--   is never actually saved to the LBI. Since <a>HookedBuildInfo</a> is
--   applied monoidally to the existing build infos (and it is not an
--   idempotent monoid), it could break things to save it, since we are
--   obligated to apply any new <a>HookedBuildInfo</a> and then we'd get
--   the effect twice. But this does mean we have to re-apply it every
--   time. Hey, it's more flexibility.

--   <tt>GenericPackageDescription</tt> which has all the conditional
--   sections. Before actually building a package we have to decide on each
--   conditional. Once we've done that we get a <a>PackageDescription</a>.
--   It was done this way initially to avoid breaking too much stuff when
--   the feature was introduced. It could probably do with being
--   rationalised at some point to make it simpler.

-- | Backwards compatibility reexport of most things you need to know about

module Distribution.PackageDescription


-- | This is about the cabal configurations feature. It exports
--   <a>finalizePD</a> and <a>flattenPackageDescription</a> which are
--   functions for converting <a>GenericPackageDescription</a>s down to
--   <a>PackageDescription</a>s. It has code for working with the tree of
--   conditions and resolving or flattening conditions.
module Distribution.PackageDescription.Configuration

-- | Create a package description with all configurations resolved.
--   
--   This function takes a <a>GenericPackageDescription</a> and several
--   environment parameters and tries to generate <a>PackageDescription</a>
--   by finding a flag assignment that result in satisfiable dependencies.
--   
--   It takes as inputs a not necessarily complete specifications of flags
--   assignments, an optional package index as well as platform parameters.
--   If some flags are not assigned explicitly, this function will try to
--   pick an assignment that causes this function to succeed. The package
--   index is optional since on some platforms we cannot determine which
--   packages have been installed before. When no package index is
--   supplied, every dependency is assumed to be satisfiable, therefore all
--   not explicitly assigned flags will get their default values.
--   
--   This function will fail if it cannot find a flag assignment that leads
--   to satisfiable dependencies. (It will not try alternative assignments
--   for explicitly specified flags.) In case of failure it will return the
--   missing dependencies that it encountered when trying different flag
--   assignments. On success, it will return the package description and
--   the full flag assignment chosen.
--   
--   Note that this drops any stanzas which have <tt>buildable: False</tt>.
--   While this is arguably the right thing to do, it means we give bad
--   error messages in some situations, see #3858.
finalizePD :: FlagAssignment -> ComponentRequestedSpec -> (Dependency -> Bool) -> Platform -> CompilerInfo -> [PackageVersionConstraint] -> GenericPackageDescription -> Either [Dependency] (PackageDescription, FlagAssignment)

-- | Flatten a generic package description by ignoring all conditions and
--   just join the field descriptors into on package description. Note,
--   however, that this may lead to inconsistent field values, since all
--   values are joined into one field, which may not be possible in the
--   original package description, due to the use of exclusive choices (if
--   ... else ...).
--   
--   TODO: One particularly tricky case is defaulting. In the original
--   package description, e.g., the source directory might either be the
--   default or a certain, explicitly set path. Since defaults are filled
--   in only after the package has been resolved and when no explicit value
--   has been set, the default path will be missing from the package
--   description returned by this function.

-- | This module provides a <tt>FieldGrammarParser</tt>, one way to parse
--   <tt>.cabal</tt> -like files.
--   
--   Fields can be specified multiple times in the .cabal files. The order
--   of such entries is important, but the mutual ordering of different
--   fields is not.Also conditional sections are considered after
--   non-conditional data. The example of this silent-commutation quirk is
--   the fact that
--   
--   <pre>
--   buildable: True
--   if os(linux)
--     buildable: False
--   </pre>
--   
--   and
--   
--   <pre>
--   if os(linux)
--     buildable: False
--   buildable: True
--   </pre>
--   
--   behave the same! This is the limitation of
--   <tt>GeneralPackageDescription</tt> structure.
--   
--   So we transform the list of fields <tt>[<a>Field</a> ann]</tt> into a
--   map of grouped ordinary fields and a list of lists of sections:
--   <tt><a>Fields</a> ann = <a>Map</a> <a>FieldName</a>
--   [<a>NamelessField</a> ann]</tt> and <tt>[[<a>Section</a> ann]]</tt>.
--   
--   We need list of list of sections, because we need to distinguish
--   situations where there are fields in between. For example
--   
--   <pre>
--   if flag(bytestring-lt-0_10_4)
--     build-depends: bytestring &lt; 0.10.4
--   
--   default-language: Haskell2020
--   
--   else
--     build-depends: bytestring &gt;= 0.10.4
--   </pre>
--   
--   is obviously invalid specification.
--   
--   We can parse <a>Fields</a> like we parse <tt>aeson</tt> objects, yet
--   we use slightly higher-level API, so we can process unspecified
--   fields, to report unknown fields and save custom <tt>x-fields</tt>.

-- | This is the information about an <i>installed</i> package that is
--   communicated to the <tt>ghc-pkg</tt> program in order to register a
--   package. <tt>ghc-pkg</tt> now consumes this package format (as of
--   version 6.4). This is specific to GHC at the moment.
--   
--   The <tt>.cabal</tt> file format is for describing a package that is
--   not yet installed. It has a lot of flexibility, like conditionals and
--   dependency ranges. As such, that format is not at all suitable for
--   describing a package that has already been built and installed. By the
--   time we get to that stage, we have resolved all conditionals and
--   resolved dependency version constraints to exact versions of dependent
--   packages. So, this module defines the <a>InstalledPackageInfo</a> data
--   structure that contains all the info we keep about an installed
--   package. There is a parser and pretty printer. The textual format is
--   rather simpler than the <tt>.cabal</tt> format: there are no sections,
--   for example.

-- | An ABI dependency is a dependency on a library which also records the

--   
--   The primary utility of this is to enable an extra sanity when GHC
--   loads libraries: it can check if the dependency has a matching ABI and
--   if not, refuse to load this library. This information is critical if
--   we are shadowing libraries; differences in the ABI hash let us know
--   what packages get shadowed by the new version of a package.
