module Distribution.Compat.Stack
type WithCallStack a = HasCallStack => a
-- | CallStacks are a lightweight method of obtaining a partial
-- call-stack at any point in the program.
--
-- A function can request its call-site with the HasCallStack
-- constraint. For example, we can define
--
--
-- putStrLnWithCallStack :: HasCallStack => String -> IO ()
--
--
-- as a variant of putStrLn that will get its call-site and
-- print it, along with the string given as argument. We can access the
-- call-stack inside putStrLnWithCallStack with
-- callStack.
--
--
-- putStrLnWithCallStack :: HasCallStack => String -> IO ()
-- putStrLnWithCallStack msg = do
-- putStrLn msg
-- putStrLn (prettyCallStack callStack)
--
--
-- Thus, if we call putStrLnWithCallStack we will get a
-- formatted call-stack alongside our string.
--
--
-- >>> putStrLnWithCallStack "hello"
-- hello
-- CallStack (from HasCallStack):
-- putStrLnWithCallStack, called at <interactive>:2:1 in interactive:Ghci1
--
--
-- GHC solves HasCallStack constraints in three steps:
--
--
-- - If there is a CallStack in scope -- i.e. the enclosing
-- function has a HasCallStack constraint -- GHC will append the
-- new call-site to the existing CallStack.
-- - If there is no CallStack in scope -- e.g. in the GHCi
-- session above -- and the enclosing definition does not have an
-- explicit type signature, GHC will infer a HasCallStack
-- constraint for the enclosing definition (subject to the monomorphism
-- restriction).
-- - If there is no CallStack in scope and the enclosing
-- definition has an explicit type signature, GHC will solve the
-- HasCallStack constraint for the singleton CallStack
-- containing just the current call-site.
--
--
-- CallStacks do not interact with the RTS and do not require
-- compilation with -prof. On the other hand, as they are built
-- up explicitly via the HasCallStack constraints, they will
-- generally not contain as much information as the simulated call-stacks
-- maintained by the RTS.
--
-- A CallStack is a [(String, SrcLoc)]. The
-- String is the name of function that was called, the
-- SrcLoc is the call-site. The list is ordered with the most
-- recently called function at the head.
--
-- NOTE: The intrepid user may notice that HasCallStack is just an
-- alias for an implicit parameter ?callStack :: CallStack. This
-- is an implementation detail and should not be considered part
-- of the CallStack API, we may decide to change the
-- implementation in the future.

-- Derived instances of Read make the following assumptions, which
-- derived instances of Show obey:
--
--
-- - If the constructor is defined to be an infix operator, then the
-- derived Read instance will parse only infix applications of the
-- constructor (not the prefix form).
-- - Associativity is not used to reduce the occurrence of parentheses,
-- although precedence may be.
-- - If the constructor is defined using record syntax, the derived
-- Read will parse only the record-syntax form, and furthermore,
-- the fields must be given in the same order as the original
-- declaration.
-- - The derived Read instance allows arbitrary Haskell
-- whitespace between tokens of the input string. Extra parentheses are
-- also allowed.
--
--
-- For example, given the declarations
--
--
-- infixr 5 :^:
-- data Tree a = Leaf a | Tree a :^: Tree a
--
--
-- the derived instance of Read in Haskell 2010 is equivalent to
--
--
-- instance (Read a) => Read (Tree a) where
--
-- readsPrec d r = readParen (d > app_prec)
-- (\r -> [(Leaf m,t) |

--
-- where app_prec = 10
-- up_prec = 5
--
--
-- Note that right-associativity of :^: is unused.
--
-- The derived instance in GHC is equivalent to
--
--
-- instance (Read a) => Read (Tree a) where
--
-- readPrec = parens $ (prec app_prec $ do
-- Ident "Leaf" <- lexP

-- v <- step readPrec
-- return (u :^: v))
--
-- where app_prec = 10
-- up_prec = 5
--
-- readListPrec = readListPrecDefault
--
--
-- Why do both readsPrec and readPrec exist, and why does
-- GHC opt to implement readPrec in derived Read instances
-- instead of readsPrec? The reason is that readsPrec is
-- based on the ReadS type, and although ReadS is mentioned
-- in the Haskell 2010 Report, it is not a very efficient parser data
-- structure.
--
-- readPrec, on the other hand, is based on a much more efficient
-- ReadPrec datatype (a.k.a "new-style parsers"), but its
-- definition relies on the use of the RankNTypes language
-- extension. Therefore, readPrec (and its cousin,
-- readListPrec) are marked as GHC-only. Nevertheless, it is
-- recommended to use readPrec instead of readsPrec
-- whenever possible for the efficiency improvements it brings.
--
-- As mentioned above, derived Read instances in GHC will
-- implement readPrec instead of readsPrec. The default
-- implementations of readsPrec (and its cousin, readList)
-- will simply use readPrec under the hood. If you are writing a
-- Read instance by hand, it is recommended to write it like so:
--
--
-- instance Read T where
-- readPrec = ...
-- readListPrec = readListPrecDefault

-- Derived instances of Show have the following properties, which
-- are compatible with derived instances of Read:
--
--
-- - The result of show 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.
-- - If the constructor is defined to be an infix operator, then
-- showsPrec will produce infix applications of the
-- constructor.
-- - the representation will be enclosed in parentheses if the
-- precedence of the top-level constructor in x is less than
-- d (associativity is ignored). Thus, if d is
-- 0 then the result is never surrounded in parentheses; if
-- d is 11 it is always surrounded in parentheses,
-- unless it is an atomic expression.
-- - If the constructor is defined using record syntax, then
-- show will produce the record-syntax form, with the fields given
-- in the same order as the original declaration.
--
--
-- For example, given the declarations
--
--
-- infixr 5 :^:
-- data Tree a = Leaf a | Tree a :^: Tree a

-- Also note that if you want an efficient left-fold, you probably want

-- that latter does not force the "inner" results (e.g. z `f` x1

-- | The Data class comprehends a fundamental primitive
-- gfoldl 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 gmap combinators later
-- in this class. Indeed, a generic programmer does not necessarily need
-- to use the ingenious gfoldl primitive but rather the intuitive
-- gmap combinators. The gfoldl 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 gmapT, gmapQ, gmapM, etc are all
-- provided with default definitions in terms of gfoldl, leaving
-- open the opportunity to provide datatype-specific definitions. (The
-- inclusion of the gmap combinators as members of class
-- Data allows the programmer or the compiler to derive
-- specialised, and maybe more efficient code per datatype. Note:
-- gfoldl is more higher-order than the gmap combinators.
-- This is subject to ongoing benchmarking experiments. It might turn out
-- that the gmap combinators will be moved out of the class
-- Data.)
--
-- Conceptually, the definition of the gmap combinators in terms
-- of the primitive gfoldl requires the identification of the
-- gfoldl function arguments. Technically, we also need to
-- identify the type constructor c for the construction of the
-- result type from the folded term type.
--
-- In the definition of gmapQx combinators, we use
-- phantom type constructors for the c in the type of
-- gfoldl because the result type of a query does not involve the
-- (polymorphic) type of the term argument. In the definition of
-- gmapQl we simply use the plain constant type constructor
-- because gfoldl 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.,
-- (:)). When the query is meant to compute a value of type
-- r, then the result type within generic folding is r ->
-- r. So the result of folding is a function to which we finally
-- pass the right unit.
--
-- With the -XDeriveDataTypeable option, GHC can generate
-- instances of the Data class automatically. For example, given
-- the declaration
--
--
-- data T a b = C1 a b | C2 deriving (Typeable, Data)
--
--
-- GHC will generate an instance that is equivalent to
--
--
-- instance (Data a, Data b) => Data (T a b) where
-- gfoldl k z (C1 a b) = z C1 `k` a `k` b
-- gfoldl k z C2 = z C2

foldMap :: (Foldable t, Monoid m) => (a -> m) -> t a -> m
-- | Right-associative fold of a structure.
--
-- In the case of lists, foldr, 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:
--
--
-- foldr f z [x1, x2, ..., xn] == x1 `f` (x2 `f` ... (xn `f` z)...)
--
--
-- Note that, since the head of the resulting expression is produced by
-- an application of the operator to the first element of the list,
-- foldr can produce a terminating expression from an infinite
-- list.
--
-- For a general Foldable structure this should be semantically
-- identical to,
--
--
-- foldr f z = foldr f z . toList
--
--
-- Examples
--
-- Basic usage:
--
--
-- >>> foldr (||) False [False, True, False]
-- True
--
--
--
-- >>> foldr (||) False []
-- False
--
--
--
-- >>> foldr (\nextChar reversedString -> reversedString ++ [nextChar]) "foo" ['a', 'b', 'c', 'd']
-- "foodcba"
--
--
-- Infinite structures
--
-- ⚠️ Applying foldr to infinite structures usually doesn't
-- terminate.
--
-- It may still terminate in one of the following conditions:
--
--
-- - the folding function is short-circuiting
-- - the folding function is lazy on its second argument
--
--
-- Short-circuiting
--
-- '(||)' short-circuits on True values, so the following
-- terminates because there is a True value finitely far from the
-- left side:
--
--
-- >>> foldr (||) False (True : repeat False)
-- True
--
--
-- But the following doesn't terminate:
--
--
-- >>> foldr (||) False (repeat False ++ [True])
-- * Hangs forever *
--
--
-- Laziness in the second argument
--
-- Applying foldr to infinite structures terminates when the
-- folding function is lazy on its second argument:
--
--
-- >>> foldr (\nextElement accumulator -> nextElement : fmap (+3) accumulator) [42] (repeat 1)
-- [1,4,7,10,13,16,19,22,25,28,31,34,37,40,43...

toList :: Foldable t => t a -> [a]
-- | Functors representing data structures that can be traversed from left

--
-- A definition of traverse must satisfy the following laws:
--
--
--
-- A definition of sequenceA must satisfy the following laws:
--
--
--
-- where an applicative transformation is a function
--
--
-- t :: (Applicative f, Applicative g) => f a -> g a
--
--
-- preserving the Applicative operations, i.e.
--
--
-- t (pure x) = pure x
-- t (f <*> x) = t f <*> t x
--
--
-- and the identity functor Identity and composition functors
-- Compose are from Data.Functor.Identity and
-- Data.Functor.Compose.
--
-- A result of the naturality law is a purity law for traverse
--
--
-- traverse pure = pure
--
--
-- (The naturality law is implied by parametricity and thus so is the
-- purity law [1, p15].)
--
-- Instances are similar to Functor, e.g. given a data type
--
--
-- data Tree a = Empty | Leaf a | Node (Tree a) a (Tree a)
--
--
-- a suitable instance would be
--
--
-- instance Traversable Tree where
-- traverse f Empty = pure Empty
-- traverse f (Leaf x) = Leaf <$> f x
-- traverse f (Node l k r) = Node <$> traverse f l <*> f k <*> traverse f r
--
--
-- This is suitable even for abstract types, as the laws for
-- <*> imply a form of associativity.
--
-- The superclass instances should satisfy the following:
--
--
-- - In the Functor instance, fmap should be equivalent
-- to traversal with the identity applicative functor
-- (fmapDefault).
-- - In the Foldable instance, foldMap should be
-- equivalent to traversal with a constant applicative functor
-- (foldMapDefault).

module Distribution.Types.CondTree
-- | A CondTree 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 a and c are usually Monoids.
--
-- To be more concrete, consider the following fragment of a
-- Cabal file:
--
--
-- build-depends: base >= 4.0
-- if flag(extra)
-- build-depends: base >= 4.2
--
--
-- One way to represent this is to have CondTree
-- ConfVar [Dependency] BuildInfo. Here,
-- condTreeData represents the actual fields which are not behind
-- any conditional, while condTreeComponents recursively records
-- any further fields which are behind a conditional.
-- condTreeConstraints records the constraints (in this case,
-- base >= 4.0) which would be applied if you use this
-- syntax; in general, this is derived off of targetBuildInfo
-- (perhaps a good refactoring would be to convert this into an opaque
-- type, with a smart constructor that pre-computes the dependencies.)

module Distribution.Types.VersionInterval
-- | A complementary representation of a VersionRange. Instead of a
-- boolean version predicate it uses an increasing sequence of
-- non-overlapping, non-empty intervals.
--
-- The key point is that this representation gives a canonical
-- representation for the semantics of VersionRanges. 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 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.

--
withinIntervals :: Version -> VersionIntervals -> Bool

-- | View a VersionRange as a union of intervals.
--
-- This provides a canonical view of the semantics of a
-- VersionRange as opposed to the syntax of the expression used to
-- define it. For the syntactic view use foldVersionRange.
--
-- Each interval is non-empty. The sequence is in increasing order and no
-- intervals overlap or touch. Therefore only the first and last can be
-- unbounded. The sequence can be empty if the range is empty (e.g. a
-- range expression like && 2).
--
-- Other checks are trivial to implement using this view. For example:
--
--
-- isNoVersion vr | [] <- asVersionIntervals vr = True
-- | otherwise = False
--
--
--
-- isSpecificVersion vr
-- | [(LowerBound v InclusiveBound
-- ,UpperBound v' InclusiveBound)] <- asVersionIntervals vr

-- | A data type representing directed graphs, backed by Data.Graph.
-- It is strict in the node type.
--
-- This is an alternative interface to Data.Graph. In this
-- interface, nodes (identified by the IsNode type class) are
-- associated with a key and record the keys of their neighbors. This
-- interface is more convenient than Graph, 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 Data.Map. However, to perform a graph
-- operation, we first must build the Data.Graph representation,
-- an operation that takes O(V + E log V). 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 broken (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.

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:
--
--
-- - A traditional library with no holes, so that unitIdHash
-- is Nothing. In the absence of Backpack, UnitId is the
-- same as a ComponentId.
-- - An indefinite, Backpack library with holes. In this case,
-- unitIdHash is still Nothing, but in the install,
-- there are only interfaces, no compiled objects.
-- - An instantiated Backpack library with all the holes filled in.
-- unitIdHash is a Just a hash of the instantiating
-- mapping.
--
--
-- 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
-- UnitId).
--
-- UnitId is distinct from OpenUnitId, in that it is
-- always installed, whereas OpenUnitId 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 UnitId, you can't actually substitute
-- over them (but you can substitute over OpenUnitId). See also
-- Distribution.Backpack.FullUnitId for a mechanism for expanding
-- an instantiated UnitId to retrieve its mapping.

module Distribution.Types.HookedBuildInfo
-- | HookedBuildInfo is mechanism that hooks can use to override the
-- BuildInfos 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 HookedBuildInfo
-- format prior to doing any operations.
--
-- Quite honestly, this mechanism is a massive hack since we shouldn't be
-- editing the PackageDescription 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 BuildInfo style things.
--
-- In any case, a lot of care has to be taken to make sure the
-- HookedBuildInfo is applied to the PackageDescription.
-- In general this process occurs in Distribution.Simple, which is
-- responsible for orchestrating the hooks mechanism. The general
-- strategy:
--
--
-- - We run the pre-hook, which produces a HookedBuildInfo
-- (e.g., in the Autoconf case, it reads it out from a file).
-- - We sanity-check the hooked build info with
-- sanityCheckHookedBuildInfo.
-- - We update our PackageDescription (either freshly read or
-- cached from LocalBuildInfo) with
-- updatePackageDescription.
--
--
-- In principle, we are also supposed to update the copy of the
-- PackageDescription stored in LocalBuildInfo at
-- localPkgDescr. Unfortunately, in practice, there are lots of
-- Custom setup scripts which fail to update localPkgDescr so
-- you really shouldn't rely on it. It's not DEPRECATED because there are
-- legitimate uses for it, but... yeah. Sharp knife. See
-- https://github.com/haskell/cabal/issues/3606 for more
-- information on the issue.
--
-- It is not well-specified whether or not a HookedBuildInfo
-- applied at configure time is persistent to the
-- LocalBuildInfo. The fact that HookedBuildInfo is
-- passed to confHook MIGHT SUGGEST that the
-- HookedBuildInfo 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 HookedBuildInfo 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 HookedBuildInfo 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.

-- | HookedBuildInfo is mechanism that hooks can use to override the
-- BuildInfos 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 HookedBuildInfo
-- format prior to doing any operations.
--
-- Quite honestly, this mechanism is a massive hack since we shouldn't be
-- editing the PackageDescription 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 BuildInfo style things.
--
-- In any case, a lot of care has to be taken to make sure the
-- HookedBuildInfo is applied to the PackageDescription.
-- In general this process occurs in Distribution.Simple, which is
-- responsible for orchestrating the hooks mechanism. The general
-- strategy:
--
--
-- - We run the pre-hook, which produces a HookedBuildInfo
-- (e.g., in the Autoconf case, it reads it out from a file).
-- - We sanity-check the hooked build info with
-- sanityCheckHookedBuildInfo.
-- - We update our PackageDescription (either freshly read or
-- cached from LocalBuildInfo) with
-- updatePackageDescription.
--
--
-- In principle, we are also supposed to update the copy of the
-- PackageDescription stored in LocalBuildInfo at
-- localPkgDescr. Unfortunately, in practice, there are lots of
-- Custom setup scripts which fail to update localPkgDescr so
-- you really shouldn't rely on it. It's not DEPRECATED because there are
-- legitimate uses for it, but... yeah. Sharp knife. See
-- https://github.com/haskell/cabal/issues/3606 for more
-- information on the issue.
--
-- It is not well-specified whether or not a HookedBuildInfo
-- applied at configure time is persistent to the
-- LocalBuildInfo. The fact that HookedBuildInfo is
-- passed to confHook MIGHT SUGGEST that the
-- HookedBuildInfo 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 HookedBuildInfo 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 HookedBuildInfo 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.

-- | A CondTree is used to represent the conditional structure of a

--
--
-- build-depends: base >= 4.0
-- if flag(extra)

-- One way to represent this is to have CondTree
-- ConfVar [Dependency] BuildInfo. Here,
-- condTreeData represents the actual fields which are not behind
-- any conditional, while condTreeComponents recursively records
-- any further fields which are behind a conditional.
-- condTreeConstraints records the constraints (in this case,

-- syntax; in general, this is derived off of targetBuildInfo
-- (perhaps a good refactoring would be to convert this into an opaque

-- | Information about the source revision control system for a package.

-- release. The ReopKind specifies which one we mean (or another

--
-- 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 RepoType which tells us if it's

[repoLocation] :: SourceRepo -> Maybe String
-- | CVS can put multiple "modules" on one server and requires a

-- Logically this is part of the location but unfortunately has to be
-- specified separately. This field is required for the CVS
-- RepoType 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 Git and CVS use this
-- while systems like Darcs use different locations for different
-- branches. This field is optional but should be used if necessary to
-- identify the sources, especially for the RepoThis repo kind.

-- | The tag identify a particular state of the repository. This should be
-- given for the RepoThis repo kind and not for RepoHead
-- kind.
[repoTag] :: SourceRepo -> Maybe String
-- | Some repositories contain multiple projects in different

-- | Desugar a "build-tools" entry into proper a executable dependency if

--
-- An entry can be so desguared in two cases:

-- - The name in build-tools matches a locally defined executable. The
-- executable dependency produced is on that exe in the current
-- package.
-- - The name in build-tools matches a hard-coded set of known tools.
-- For now, the executable dependency produced is one an executable in a

-- per-key.
--
--
-- The first cases matches first.
desugarBuildTool :: PackageDescription -> LegacyExeDependency -> Maybe ExeDependency
-- | Get everything from "build-tool-depends", along with entries from
-- "build-tools" that we know how to desugar.
--
-- This should almost always be used instead of just accessing the

getAllToolDependencies :: PackageDescription -> BuildInfo -> [ExeDependency]
-- | Does the given executable dependency map to this current package?
--
-- This is a tiny function, but used in a number of places.
--
-- This function is only sound to call on BuildInfos from the
-- given package description. This is because it just filters the package
-- names of each dependency, and does not check whether version bounds in
-- fact exclude the current package, or the referenced components in fact
-- exist in the current package.
--
-- This is OK because when a package is loaded, it is checked (in
-- Check) that dependencies matching internal components do indeed
-- have version bounds accepting the current package, and any depended-on
-- component in the current package actually exists. In fact this check
-- is performed by gathering the internal tool dependencies of each
-- component of the package according to this module, and ensuring those
-- properties on each so-gathered dependency.
--
-- version bounds and components of the package are unchecked. This is
-- because we sanitize exe deps so that the matching name implies these
-- other conditions.
isInternal :: PackageDescription -> ExeDependency -> Bool
-- | Get internal "build-tool-depends", along with internal "build-tools"
--
-- This is a tiny function, but used in a number of places. The same

-- | This manages everything to do with where files get installed (though

-- relative to some $prefix and by changing the prefix all other

-- PathTemplate type and functions for substituting for these

-- | The installation directories in terms of PathTemplates that

--
-- The defaults for most of the directories are relative to each other,

-- convenient for the user to override the default installation directory
-- by only having to specify --prefix=... rather than overriding each
-- individually. This is done by allowing $-style variables in the dirs.
-- These are expanded by textual substitution (see
-- substPathTemplate).
--
-- A few of these installation directories are split into two components,
-- the dir and subdir. The full installation path is formed by combining
-- the two together with /. The reason for this is compatibility
-- with other Unix build systems which also support --libdir and
-- --datadir. We would like users to be able to configure
-- --libdir=/usr/lib64 for example but because by default we
-- want to support installing multiple versions of packages and building
-- the same package for multiple compilers we append the libsubdir to
-- get: /usr/lib64/$libname/$compiler.
--
-- An additional complication is the need to support relocatable packages
-- on systems which support such things, like Windows.

instance GHC.Base.Functor Distribution.Simple.Command.CommandParse
-- | This is a big module, but not very complicated. The code is very
-- regular and repetitive. It defines the command line interface for all
-- the Cabal commands. For each command (like configure,
-- build etc) it defines a type that holds all the flags, the
-- default set of flags and a CommandUI that maps command line
-- flags to and from the corresponding flags type.
--
-- All the flags types are instances of Monoid, see
-- http://www.haskell.org/pipermail/cabal-devel/2007-December/001509.html
-- for an explanation.
--
-- The types defined here get used in the front end and especially in
-- cabal-install which has to do quite a bit of manipulating
-- sets of command line flags.
--
-- This is actually relatively nice, it works quite well. The main change
-- it needs is to unify it with the code for managing sets of fields that
-- can be read and written from files. This would allow us to save
-- configure flags in config files.

-- functions for converting GenericPackageDescriptions down to
-- PackageDescriptions. 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 GenericPackageDescription and several
-- environment parameters and tries to generate PackageDescription
-- 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 buildable: False.
-- 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 -> [Dependency] -> 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 is an alternative build system that delegates everything to the
-- make program. All the commands just end up calling
-- make with appropriate arguments. The intention was to allow
-- preexisting packages that used makefiles to be wrapped into Cabal
-- packages. In practice essentially all such packages were converted
-- over to the "Simple" build system instead. Consequently this module is
-- not used much and it certainly only sees cursory maintenance and no
-- testing. Perhaps at some point we should stop pretending that it
-- works.
--
-- Uses the parsed command-line from Distribution.Simple.Setup in
-- order to build Haskell tools using a back-end build system based on
-- make. Obviously we assume that there is a configure script, and that
-- after the ConfigCmd has been run, there is a Makefile. Further
-- assumptions:
--
--
-- - ConfigCmd We assume the configure script accepts
-- --with-hc, --with-hc-pkg, --prefix,
-- --bindir, --libdir, --libexecdir,
-- --datadir.
-- - BuildCmd We assume that the default Makefile target will
-- build everything.
-- - InstallCmd We assume there is an install target.
-- Note that we assume that this does *not* register the package!
-- - CopyCmd We assume there is a copy target, and a
-- variable $(destdir). The copy target should probably
-- just invoke make install recursively (e.g. $(MAKE)
-- install prefix=$(destdir)/$(prefix) bindir=$(destdir)/$(bindir).
-- The reason we can't invoke make install directly here is that
-- we don't know the value of $(prefix).
-- - SDistCmd We assume there is a dist target.
-- - RegisterCmd We assume there is a register target
-- and a variable $(user).
-- - UnregisterCmd We assume there is an unregister
-- target.
-- - HaddockCmd We assume there is a docs or
-- doc target.

-- | This is the information about an installed package that is

--
-- The .cabal 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 InstalledPackageInfo 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 .cabal format: there are no sections,
-- for example.

-- database which is used by GHC during compilation. For example, this
-- data structure is used by 'ghc-pkg' and Cabal to do
-- consistency checks on the database (are the references closed).
-- - Given a set of dependencies, we can compute the transitive closure
-- of dependencies. This is to check if the versions of packages are
-- consistent, and also needed by multiple tools (Haddock must be

-- linking; preprocessors must know about the include paths of all
-- transitive dependencies.)

-- individually. This is done by allowing $-style variables in the dirs.
-- These are expanded by textual substitution (see
-- substPathTemplate).
--
-- A few of these installation directories are split into two components,
-- the dir and subdir. The full installation path is formed by combining
-- the two together with /. The reason for this is compatibility
-- with other Unix build systems which also support --libdir and
-- --datadir. We would like users to be able to configure
-- --libdir=/usr/lib64 for example but because by default we
-- want to support installing multiple versions of packages and building

-- | This is a fairly large module. It contains most of the GHC-specific

-- version of ghc supports and returning a Compiler value.
--
-- getInstalledPackages involves calling the ghc-pkg
-- program to find out what packages are installed.
--
-- Building is somewhat complex as there is quite a bit of information to
-- take into account. We have to build libs and programs, possibly for
-- profiling and shared libs. We have to support building libraries that
-- will be usable by GHCi and also ghc's -split-objs feature. We
-- have to compile any C files using ghc. Linking, especially for
-- split-objs is remarkably complex, partly because there tend
-- to be 1,000's of .o files and this can often be more than we
-- can pass to the ld or ar programs in one go.
--
-- Installing for libs and exes involves finding the right files and
-- copying them to the right places. One of the more tricky things about
-- this module is remembering the layout of files in the build directory
-- (which is not explicitly documented) and thus what search dirs are
-- used for various kinds of files.

--
--
-- - type: the type of the component (one of lib,
-- exe, test, bench, or flib)
-- - name: a string serving to uniquely identify the component
-- within the package.
-- - compiler-args: the command-line arguments Cabal would

-- - src-dirs: a list of directories where the modules might
-- be found
-- - src-files: any other Haskell sources needed by the

-- | This module deals with registering and unregistering packages. There
-- are a couple ways it can do this, one is to do it directly. Another is
-- to generate a script that can be run later to do it. The idea here
-- being that the user is shielded from the details of what command to
-- use for package registration for a particular compiler. In practice
-- this aspect was not especially popular so we also provide a way to
-- simply generate the package registration file which then must be
-- manually passed to ghc-pkg. It is possible to generate
-- registration information for where the package is to be installed, or
-- alternatively to register the package in place in the build tree. The
-- latter is occasionally handy, and will become more important when we
-- try to build multi-package systems.
--
-- This module does not delegate anything to the per-compiler modules but
-- just mixes it all in in this module, which is rather unsatisfactory.
-- The script generation and the unregister feature are not well used or
-- tested.

-- | This defines a PreProcessor abstraction which represents a

-- | The interface to a preprocessor, which may be implemented using an
-- external program, but need not be. The arguments are the name of the
-- input file, the name of the output file and a verbosity level. Here is
-- a simple example that merely prepends a comment to the given source
-- file:
--
--
-- ppTestHandler :: PreProcessor
-- ppTestHandler =
-- PreProcessor {
-- platformIndependent = True,
-- runPreProcessor = mkSimplePreProcessor $ \inFile outFile verbosity ->
-- do info verbosity (inFile++" has been preprocessed to "++outFile)
-- stuff <- readFile inFile
-- writeFile outFile ("-- preprocessed as a test\n\n" ++ stuff)
-- return ExitSuccess
--
--
-- We split the input and output file names into a base directory and the
-- rest of the file name. The input base dir is the path in the list of
-- search dirs that this file was found in. The output base dir is the
-- build dir where all the generated source files are put.
--
-- The reason for splitting it up this way is that some pre-processors
-- don't simply generate one output .hs file from one input file but have
-- dependencies on other generated files (notably c2hs, where building
-- one .hs file may require reading other .chi files, and then compiling
-- the .hs file may require reading a generated .h file). In these cases
-- the generated files need to embed relative path names to each other
-- (eg the generated .hs file mentions the .h file in the FFI imports).
-- This path must be relative to the base directory where the generated
-- files are located, it cannot be relative to the top level of the build
-- tree because the compilers do not look for .h files relative to there,
-- ie we do not use "-I .", instead we use "-I dist/build" (or whatever
-- dist dir has been set by the user)
--
-- Most pre-processors do not care of course, so mkSimplePreProcessor and
-- runSimplePreProcessor functions handle the simple case.

-- | This defines the API that Setup.hs scripts can use to

-- are defined in Distribution.Simple. The UserHooks is a
-- big record of functions. There are 3 for each action, a pre, post and

-- extend the set of programs and preprocessors and one to override the
-- function used to read the .cabal file.
--
-- This hooks type is widely agreed to not be the right solution. Partly
-- this is because changes to it usually break custom Setup.hs
-- files and yet many internal code changes do require changes to the
-- hooks. For example we cannot pass any extra parameters to most of the
-- functions that implement the various phases because it would involve
-- changing the types of the corresponding hook. At some point it will

computeComponentId :: Bool -> Flag String -> Flag ComponentId -> PackageIdentifier -> ComponentName -> Maybe ([ComponentId], FlagAssignment) -> ComponentId
-- | In GHC 8.0, the string we pass to GHC to use for symbol names for a
-- package can be an arbitrary, IPID-compatible string. However, prior to
-- GHC 8.0 there are some restrictions on what format this string can be
-- (due to how ghc-pkg parsed the key):
--
--
-- - In GHC 7.10, the string had either be of the form foo_ABCD, where
-- foo is a non-semantic alphanumeric/hyphenated prefix and ABCD is two
-- base-64 encoded 64-bit integers, or a GHC 7.8 style identifier.
-- - In GHC 7.8, the string had to be a valid package identifier like
-- foo-0.1.
--
--
-- So, the problem is that Cabal, in general, has a general IPID, but
-- needs to figure out a package key / package ID that the old ghc-pkg
-- will actually accept. But there's an EVERY WORSE problem: if ghc-pkg
-- decides to parse an identifier foo-0.1-xxx as if it were a package
-- identifier, which means it will SILENTLY DROP the "xxx" (because it's
-- a tag, and Cabal does not allow tags.) So we must CONNIVE to ensure
-- that we don't pick something that looks like this.
--
-- So this function attempts to define a mapping into the old formats.
--
-- The mapping for GHC 7.8 and before:
--
--
-- - We use the *compatibility* package name and version. For public
-- libraries this is just the package identifier; for internal libraries,
-- it's something like "z-pkgname-z-libname-0.1". See
-- computeCompatPackageName for more details.
--
--
-- The mapping for GHC 7.10:
--
--
-- - For CLibName: If the IPID is of the form foo-0.1-ABCDEF where
-- foo_ABCDEF would validly parse as a package key, we pass
-- ABCDEF. (NB: not all hashes parse this way, because GHC 7.10
-- mandated that these hashes be two base-62 encoded 64 bit integers),
-- but hashes that Cabal generated using computeComponentId are
-- guaranteed to have this form.If it is not of this form, we rehash the
-- IPID into the correct form and pass that.
-- - For sub-components, we rehash the IPID into the correct format and
-- pass that.
