module Distribution.Compat.Stack
type WithCallStack a = HasCallStack => a

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

-- | This is a library of parser combinators, originally written by Koen

--   Why do both <a>readsPrec</a> and <a>readPrec</a> exist, and why does
--   GHC opt to implement <a>readPrec</a> in derived <a>Read</a> instances
--   instead of <a>readsPrec</a>? The reason is that <a>readsPrec</a> is
--   based on the <a>ReadS</a> type, and although <a>ReadS</a> is mentioned
--   in the Haskell 2010 Report, it is not a very efficient parser data
--   structure.
--   
--   <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>
--   whenever possible for the efficiency improvements it brings.
--   
--   As mentioned above, derived <a>Read</a> instances in GHC will
--   implement <a>readPrec</a> instead of <a>readsPrec</a>. The default
--   implementations of <a>readsPrec</a> (and its cousin, <a>readList</a>)
--   will simply use <a>readPrec</a> under the hood. If you are writing a
--   <a>Read</a> instance by hand, it is recommended to write it like so:
--   
--   <pre>
--   instance <a>Read</a> T where
--     <a>readPrec</a>     = ...
--     <a>readListPrec</a> = <a>readListPrecDefault</a>

--   Derived instances of <a>Show</a> have the following properties, which

--   
--   <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>

--   
--          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) $

--   </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

--   
--   Further, any definition must satisfy the following:

--   <ul>
--   <li><i><i>identity</i></i> <pre><a>pure</a> <a>id</a> <a>&lt;*&gt;</a>

--   </ul>
--   
--   The other methods have the following default definitions, which may be

--   <pre>
--   forall x y. p (q x y) = f x . g y

--   
--   it follows from the above that

-- | Left-associative fold of a structure.
--   
--   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

--   <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. This means that <a>foldl'</a>
--   will diverge if given an infinite list.
--   
--   Also note that if you want an efficient left-fold, you probably want
--   to use <a>foldl'</a> instead of <a>foldl</a>. The reason for this is

--   x1</tt> in the above example) before applying them to the operator
--   (e.g. to <tt>(<tt>f</tt> x2)</tt>). This results in a thunk chain

--   <a>Integer</a> values. A rational number may be constructed using the
--   <a>%</a> operator.
type Rational = Ratio 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
--           parseMultiple = do
--             x &lt;- parseEither 'm'
--             y &lt;- parseEither '2'
--             return (x + y)
--   
--   &gt;&gt;&gt; :}

readFile :: FilePath -> IO String

-- | The <a>interact</a> function takes a function of type

--   <pre>
--   &gt;&gt;&gt; unlines ["Hello", "World", "!"]
--   "Hello\nWorld\n!\n"

unlines :: [String] -> String

-- | <a>lines</a> breaks a string up into a list of strings at newline
--   characters. The resulting strings do not contain newlines.
--   
--   Note that after splitting the string at newline characters, the last
--   part of the string is considered a line even if it doesn't end with a
--   newline. For example,
--   
--   <pre>
--   &gt;&gt;&gt; lines ""

--   <pre>
--   &gt;&gt;&gt; lines "\n"

-- | The <a>lex</a> function reads a single lexeme from the input,

-- | The class <a>Typeable</a> allows a concrete representation of a type

class Typeable (a :: k)

-- | 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 withing 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

--   
--       gunfold k z c = case constrIndex c of
--                           1 -&gt; k (k (z C1))
--                           2 -&gt; z C2

-- | A data type representing directed graphs, backed by <a>Data.Graph</a>.

--   The current implementation has somewhat peculiar performance

module Distribution.Types.CondTree

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

--   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>

-- | <a>isAbsoluteOnAnyPlatform</a> and <a>isRelativeOnAnyPlatform</a> are

--   Windows and Posix. The two versions don't agree on what is a relative
--   path and we don't know if we're given Windows or Posix paths. This
--   results in false positives when running on Posix and inspecting
--   Windows paths, like the hackage server does.
--   System.FilePath.Posix.isAbsolute "C:\hello" == False
--   System.FilePath.Windows.isAbsolute "/hello" == False This means that
--   we would treat paths that start with "/" to be absolute. On Posix they
--   are indeed absolute, while on Windows they are not.
--   
--   The portable versions should be used when we might deal with paths
--   that are from another OS than the host OS. For example, the Hackage
--   Server deals with both Windows and Posix paths while performing the
--   PackageDescription checks. In contrast, when we run 'cabal configure'
--   we do expect the paths to be correct for our OS and we should not have
--   to use the platform independent heuristics.

module Distribution.Types.VersionInterval

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

--   The key point is that this representation gives a canonical

--   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

--

module Distribution.Types.SourceRepo

-- | Information about the source revision control system for a package.
--   
--   When specifying a repo it is useful to know the meaning or intention
--   of the information as doing so enables automation. There are two
--   obvious common purposes: one is to find the repo for the latest
--   development version, the other is to find the repo for this specific
--   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

-- | The kind of repo. This field is required.
[repoKind] :: SourceRepo -> RepoKind

-- | The type of the source repository system for this repo, eg
--   <a>Darcs</a> or <a>Git</a>. This field is required.
[repoType] :: SourceRepo -> Maybe RepoType

-- | The location of the repository. For most <a>RepoType</a>s this is a
--   URL. This field is required.
[repoLocation] :: SourceRepo -> Maybe String

-- | <a>CVS</a> can put multiple "modules" on one server and requires a
--   module name in addition to the location to identify a particular repo.
--   Logically this is part of the location but unfortunately has to be
--   specified separately. This field is required for the <a>CVS</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.

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

-- | The repository for the "head" or development version of the project.
--   This repo is where we should track the latest development activity or

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

--   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

--   
--   For parsing OS and arch names in .cabal files we really want everyone
--   to be referring to the same or 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

-- | This has an enumeration of the various compilers that Cabal knows
--   about. It also specifies the default compiler. Sadly you'll often see
--   code that does case analysis on this compiler flavour enumeration
--   like:
--   
--   <pre>
--   case compilerFlavor comp of
--     GHC -&gt; GHC.getInstalledPackages verbosity packageDb progdb
--   </pre>
--   
--   Obviously it would be better to use the proper <tt>Compiler</tt>
--   abstraction because that would keep all the compiler-specific code
--   together. Unfortunately we cannot make this change yet without
--   breaking the <tt>UserHooks</tt> api, which would break all custom
--   <tt>Setup.hs</tt> files, so for the moment we just have to live with
--   this deficiency. If you're interested, see ticket #57.

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 <a>display</a> function, which will work on all versions

--   
--   
--   <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 lossly
--   represent it as an 'OpenUnitId 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>.

mkMungedPackageName :: String -> MungedPackageName

-- | Computes the package name for a library. If this is the public
--   library, it will just be the original package name; otherwise, it will
--   be a munged package name recording the original package name as well
--   as the name of the internal library.
--   
--   A lot of tooling in the Haskell ecosystem assumes that if something is
--   installed to the package database with the package name <tt>foo</tt>,
--   then it actually is an entry for the (only public) library in package
--   <tt>foo</tt>. With internal packages, this is not necessarily true: a
--   public library as well as arbitrarily many internal libraries may come
--   from the same package. To prevent tools from getting confused in this
--   case, the package name of these internal libraries is munged so that
--   they do not conflict the public library proper. A particular case
--   where this matters is ghc-pkg: if we don't munge the package name, the
--   inplace registration will OVERRIDE a different internal library.
--   
--   We munge into a reserved namespace, "z-", and encode both the
--   component name and the package name of an internal library using the
--   following format:
--   
--   compat-pkg-name ::= "z-" package-name "-z-" library-name
--   
--   where package-name and library-name have "-" ( "z" + ) "-" segments
--   encoded by adding an extra "z".
--   
--   When we have the public library, the compat-pkg-name is just the
--   package-name, no surprises there!

-- | The directories where we will install files for packages.

-- | The installation directories in terms of <a>PathTemplate</a>s that
--   contain variables.
--   
--   The defaults for most of the directories are relative to each other,
--   in particular they are all relative to a single prefix. This makes it
--   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 $-style variables in the dirs.
--   These are expanded by textual substitution (see
--   <a>substPathTemplate</a>).
--   
--   A few of these installation directories are split into two components,
--   the dir and subdir. The full installation path is formed by combining
--   the two together with <tt>/</tt>. The reason for this is compatibility
--   with other Unix build systems which also support <tt>--libdir</tt> and
--   <tt>--datadir</tt>. We would like users to be able to configure
--   <tt>--libdir=/usr/lib64</tt> for example but because by default we
--   want to support installing multiple versions of packages and building
--   the same package for multiple compilers we append the libsubdir to
--   get: <tt>/usr/lib64/$libname/$compiler</tt>.
--   
--   An additional complication is the need to support relocatable packages
--   on systems which support such things, like Windows.

module Distribution.Types.LegacyExeDependency

-- | Describes a legacy `build-tools`-style dependency on an executable
--   
--   It is "legacy" because we do not know what the build-tool referred to.
--   It could refer to a pkg-config executable (PkgconfigName), or an
--   internal executable (UnqualComponentName). Thus the name is stringly
--   typed.

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.

-- | This defines the data structure for the <tt>.cabal</tt> file format.
--   There are several parts to this structure. It has top level info and
--   then <a>Library</a>, <a>Executable</a>, <a>TestSuite</a>, and
--   <a>Benchmark</a> sections each of which have associated
--   <a>BuildInfo</a> data that's used to build the library, exe, test, or
--   benchmark. To further complicate things there is both a
--   <a>PackageDescription</a> and a <tt>GenericPackageDescription</tt>.
--   This distinction relates to cabal configurations. When we initially
--   read a <tt>.cabal</tt> file we get a
--   <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.

-- | <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.

-- | Information about the source revision control system for a package.
--   
--   When specifying a repo it is useful to know the meaning or intention
--   of the information as doing so enables automation. There are two
--   obvious common purposes: one is to find the repo for the latest
--   development version, the other is to find the repo for this specific
--   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

-- | The kind of repo. This field is required.
[repoKind] :: SourceRepo -> RepoKind

-- | The type of the source repository system for this repo, eg
--   <a>Darcs</a> or <a>Git</a>. This field is required.
[repoType] :: SourceRepo -> Maybe RepoType

-- | The location of the repository. For most <a>RepoType</a>s this is a
--   URL. This field is required.
[repoLocation] :: SourceRepo -> Maybe String

-- | <a>CVS</a> can put multiple "modules" on one server and requires a
--   module name in addition to the location to identify a particular repo.
--   Logically this is part of the location but unfortunately has to be
--   specified separately. This field is required for the <a>CVS</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.
RepoHead :: RepoKind

-- | The repository containing the sources for this exact package version
--   or release. For this kind of repo a tag should be given to give enough
--   information to re-create the exact sources.
RepoThis :: RepoKind
RepoKindUnknown :: String -> RepoKind

-- | An enumeration of common source control systems. The fields used in
--   the <a>SourceRepo</a> depend on the type of repo. The tools and
--   methods used to obtain and track the repo depend on the repo type.

SetupBuildInfo :: [Dependency] -> Bool -> SetupBuildInfo
[setupDepends] :: SetupBuildInfo -> [Dependency]

-- | Is this a default 'custom-setup' section added by the cabal-install
--   code (as opposed to user-provided)? This field is only used
--   internally, and doesn't correspond to anything in the .cabal file. See
--   #3199.
[defaultSetupDepends] :: SetupBuildInfo -> Bool


-- | This modules provides functions for working with both the legacy
--   "build-tools" field, and its replacement, "build-tool-depends". Prefer
--   using the functions contained to access those fields directly.
module Distribution.Simple.BuildToolDepends

-- | Desugar a "build-tools" entry into proper a executable dependency if
--   possible.
--   
--   An entry can be so desguared in two cases:
--   
--   <ol>
--   <li>The name in build-tools matches a locally defined executable. The
--   executable dependency produced is on that exe in the current
--   package.</li>
--   <li>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
--   package of the same, but the hard-coding could just as well be
--   per-key.</li>
--   </ol>
--   
--   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
--   <a>buildToolDepends</a> field directly.
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 <a>BuildInfo</a>s 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
--   <a>Check</a>) 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
--   restrictions that apply to <a>isInternal</a> also apply to this
--   function.

-- | A large and somewhat miscellaneous collection of utility functions
--   used throughout the rest of the Cabal lib and in other tools that use
--   the Cabal lib like <tt>cabal-install</tt>. It has a very simple set of
--   logging actions. It has low level functions for running programs, a
--   bunch of wrappers for various directory and file functions that do
--   extra logging.
module Distribution.Simple.Utils
cabalVersion :: Version

-- | <i>Deprecated: Messages thrown with die can't be controlled with

die :: String -> IO a

dieNoWrap :: Verbosity -> String -> IO a
topHandler :: IO a -> IO a

-- | Non fatal conditions that may be indicative of an error or problem.
--   
--   We display these at the <a>normal</a> verbosity level.
warn :: Verbosity -> String -> IO ()

-- | Useful status messages.
--   
--   We display these at the <a>normal</a> verbosity level.
--   
--   This is for the ordinary helpful status messages that users see. Just
--   enough information to know that things are working but not floods of
--   detail.
notice :: Verbosity -> String -> IO ()

-- | Display a message at <a>normal</a> verbosity level, but without
--   wrapping.
noticeNoWrap :: Verbosity -> String -> IO ()

-- | Pretty-print a <a>Doc</a> status message at <a>normal</a> verbosity

noticeDoc :: Verbosity -> Doc -> IO ()

-- | Display a "setup status message". Prefer using setupMessage' if

setupMessage :: Verbosity -> String -> PackageIdentifier -> IO ()

-- | More detail on the operation of some action.
--   
--   We display these messages when the verbosity level is <a>verbose</a>
info :: Verbosity -> String -> IO ()
infoNoWrap :: Verbosity -> String -> IO ()

-- | Detailed internal debugging information
--   
--   We display these messages when the verbosity level is <a>deafening</a>
debug :: Verbosity -> String -> IO ()

-- | A variant of <a>debug</a> that doesn't perform the automatic line

debugNoWrap :: Verbosity -> String -> IO ()

-- | Perform an IO action, catching any IO exceptions and printing an error
--   if one occurs.
chattyTry :: String -> IO () -> IO ()

-- | Given a block of IO code that may raise an exception, annotate it with
--   the metadata from the current scope. Use this as close to external
--   code that raises IO exceptions as possible, since this function
--   unconditionally wraps the error message with a trace (so it is NOT

printRawCommandAndArgs :: Verbosity -> FilePath -> [String] -> IO ()
printRawCommandAndArgsAndEnv :: Verbosity -> FilePath -> [String] -> Maybe FilePath -> Maybe [(String, String)] -> IO ()

-- | Wrap output with a marker if <tt>+markoutput</tt> verbosity flag is

--   
--   NB: Why is markoutput done with start/end markers, and not prefixes?
--   Markers are more convenient to add (if we want to add prefixes, we
--   have to <a>lines</a> and then <a>map</a>; here's it's just some
--   concatenates). Note that even in the prefix case, we can't guarantee
--   that the markers are unambiguous, because some of Cabal's output comes

rawSystemStdout :: Verbosity -> FilePath -> [String] -> IO String

-- | Run a command and return its output, errors and exit status.

maybeExit :: IO ExitCode -> IO ()

-- | Like the Unix xargs program. Useful for when we've got very long

--   and so you need to invoke a command multiple times to get all the args
--   in.
--   
--   Use it with either of the rawSystem variants above. For example:
--   
--   <pre>
--   xargs (32*1024) (rawSystemExit verbosity) prog fixedArgs bigArgs

findProgramLocation :: Verbosity -> FilePath -> IO (Maybe FilePath)

-- | Look for a program and try to find it's version number. It can accept

--   we will look for the program on the path.
findProgramVersion :: String -> (String -> String) -> Verbosity -> FilePath -> IO (Maybe Version)

smartCopySources :: Verbosity -> [FilePath] -> FilePath -> [ModuleName] -> [String] -> IO ()

-- | Same as <tt>createDirectoryIfMissing</tt> but logs at higher verbosity
--   levels.
createDirectoryIfMissingVerbose :: Verbosity -> Bool -> FilePath -> IO ()

-- | Copies a file without copying file permissions. The target file is
--   created with default permissions. Any existing target file is
--   replaced.
--   
--   At higher verbosity levels it logs an info message.
copyFileVerbose :: Verbosity -> FilePath -> FilePath -> IO ()

-- | <i>Deprecated: You probably want installDirectoryContents instead</i>
copyDirectoryRecursiveVerbose :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Copies a bunch of files to a target directory, preserving the
--   directory structure in the target location. The target directories are
--   created if they do not exist.
--   
--   The files are identified by a pair of base directory and a path
--   relative to that base. It is only the relative part that is preserved
--   in the destination.
--   
--   For example:
--   
--   <pre>
--   copyFiles normal "dist/src"
--      [("", "src/Foo.hs"), ("dist/build/", "src/Bar.hs")]
--   </pre>
--   
--   This would copy "src/Foo.hs" to "dist/src/src/Foo.hs" and copy
--   "dist/build/src/Bar.hs" to "dist/src/src/Bar.hs".
--   
--   This operation is not atomic. Any IO failure during the copy
--   (including any missing source files) leaves the target in an unknown
--   state so it is best to use it with a freshly created directory so that
--   it can be simply deleted if anything goes wrong.
copyFiles :: Verbosity -> FilePath -> [(FilePath, FilePath)] -> IO ()

-- | Given a relative path to a file, copy it to the given directory,
--   preserving the relative path and creating the parent directories if
--   needed.
copyFileTo :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Install an ordinary file. This is like a file copy but the permissions
--   are set appropriately for an installed file. On Unix it is
--   "-rw-r--r--" while on Windows it uses the default permissions for the
--   target directory.
installOrdinaryFile :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Install an executable file. This is like a file copy but the
--   permissions are set appropriately for an installed file. On Unix it is
--   "-rwxr-xr-x" while on Windows it uses the default permissions for the
--   target directory.
installExecutableFile :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Install a file that may or not be executable, preserving permissions.
installMaybeExecutableFile :: Verbosity -> FilePath -> FilePath -> IO ()

-- | This is like <a>copyFiles</a> but uses <a>installOrdinaryFile</a>.
installOrdinaryFiles :: Verbosity -> FilePath -> [(FilePath, FilePath)] -> IO ()

-- | This is like <a>copyFiles</a> but uses <a>installExecutableFile</a>.
installExecutableFiles :: Verbosity -> FilePath -> [(FilePath, FilePath)] -> IO ()

-- | This is like <a>copyFiles</a> but uses
--   <a>installMaybeExecutableFile</a>.
installMaybeExecutableFiles :: Verbosity -> FilePath -> [(FilePath, FilePath)] -> IO ()

-- | This installs all the files in a directory to a target location,
--   preserving the directory layout. All the files are assumed to be
--   ordinary rather than executable files.
installDirectoryContents :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Recursively copy the contents of one directory to another path.
copyDirectoryRecursive :: Verbosity -> FilePath -> FilePath -> IO ()

-- | Like <a>doesFileExist</a>, but also checks that the file is
--   executable.
doesExecutableExist :: FilePath -> NoCallStackIO Bool
setFileOrdinary :: FilePath -> NoCallStackIO ()
setFileExecutable :: FilePath -> NoCallStackIO ()

-- | The path name that represents the current directory. In Unix, it's

currentDir :: FilePath
shortRelativePath :: FilePath -> FilePath -> FilePath

-- | Drop the extension if it's one of <a>exeExtensions</a>, or return the

dropExeExtension :: FilePath -> FilePath

-- | List of possible executable file extensions on the current platform.
exeExtensions :: [String]

-- | Find a file by looking in a search path. The file path must match

findFile :: [FilePath] -> FilePath -> IO FilePath
findFirstFile :: (a -> FilePath) -> [a] -> NoCallStackIO (Maybe a)

-- | Find a file by looking in a search path with one of a list of possible
--   file extensions. The file base name should be given and it will be
--   tried with each of the extensions in each element of the search path.
findFileWithExtension :: [String] -> [FilePath] -> FilePath -> NoCallStackIO (Maybe FilePath)

-- | Like <a>findFileWithExtension</a> but returns which element of the

--   base directory.
findFileWithExtension' :: [String] -> [FilePath] -> FilePath -> NoCallStackIO (Maybe (FilePath, FilePath))
findAllFilesWithExtension :: [String] -> [FilePath] -> FilePath -> NoCallStackIO [FilePath]

-- | Find the file corresponding to a Haskell module name.
--   
--   This is similar to <a>findFileWithExtension'</a> but specialised to a
--   module name. The function fails if the file corresponding to the
--   module is missing.
findModuleFile :: [FilePath] -> [String] -> ModuleName -> IO (FilePath, FilePath)

-- | Finds the files corresponding to a list of Haskell module names.
--   
--   As <a>findModuleFile</a> but for a list of module names.
findModuleFiles :: [FilePath] -> [String] -> [ModuleName] -> IO [(FilePath, FilePath)]

-- | List all the files in a directory and all subdirectories.
--   
--   The order places files in sub-directories after all the files in their
--   parent directories. The list is generated lazily so is not well
--   defined if the source directory structure changes before the list is
--   used.
getDirectoryContentsRecursive :: FilePath -> IO [FilePath]

-- | Is this directory in the system search path?
isInSearchPath :: FilePath -> NoCallStackIO Bool
addLibraryPath :: OS -> [FilePath] -> [(String, String)] -> [(String, String)]

-- | Compare the modification times of two files to see if the first is
--   newer than the second. The first file must exist but the second need
--   not. The expected use case is when the second file is generated using
--   the first. In this use case, if the result is True then the second
--   file is out of date.
moreRecentFile :: FilePath -> FilePath -> NoCallStackIO Bool

-- | Like <a>moreRecentFile</a>, but also checks that the first file

-- | A somewhat extended notion of the normal program search path concept.

--   Usually when finding executables we just want to look in the usual
--   places using the OS's usual method for doing so. In Haskell the normal
--   OS-specific method is captured by <a>findExecutable</a>. On all common
--   OSs that makes use of a <tt>PATH</tt> environment variable, (though on
--   Windows it is not just the <tt>PATH</tt>).
--   
--   However it is sometimes useful to be able to look in additional
--   locations without having to change the process-global <tt>PATH</tt>
--   environment variable. So we need an extension of the usual
--   <a>findExecutable</a> that can look in additional locations, either
--   before, after or instead of the normal OS locations.

module Distribution.Simple.Program.Hpc

-- | Invoke hpc with the given parameters.
--   
--   Prior to HPC version 0.7 (packaged with GHC 7.8), hpc did not handle
--   multiple .mix paths correctly, so we print a warning, and only pass it
--   the first path in the list. This means that e.g. test suites that

-- | This should be a much more sophisticated abstraction than it is.
--   Currently it's just a bit of data about the compiler, like its flavour
--   and name and version. The reason it's just data is because currently
--   it has to be in <a>Read</a> and <a>Show</a> so it can be saved along
--   with the <tt>LocalBuildInfo</tt>. The only interesting bit of info it
--   contains is a mapping between language extensions and compiler command
--   line flags. This module also defines a <a>PackageDB</a> type which is
--   used to refer to package databases. Most compilers only know about a
--   single global package collection but GHC has a global and per-user one
--   and it lets you create arbitrary other package databases. We do not

instance Data.Binary.Class.Binary Distribution.Simple.Program.Db.ProgramDb


-- | This provides an abstraction which deals with configuring and running
--   programs. A <a>Program</a> is a static notion of a known program. A
--   <a>ConfiguredProgram</a> is a <a>Program</a> that has been found on
--   the current machine and is ready to be run (possibly with some
--   user-supplied default args). Configuring a program involves finding
--   its location and if necessary finding its version. There is also a
--   <a>ProgramDb</a> type which holds configured and not-yet configured
--   programs. It is the parameter to lots of actions elsewhere in Cabal
--   that need to look up and run programs. If we had a Cabal monad, the
--   <a>ProgramDb</a> would probably be a reader or state component of it.
--   
--   The module also defines all the known built-in <a>Program</a>s and the
--   <a>defaultProgramDb</a> which contains them all.
--   
--   One nice thing about using it is that any program that is registered
--   with Cabal will get some "configure" and ".cabal" helpers like
--   --with-foo-args --foo-path= and extra-foo-args.
--   
--   There's also good default behavior for trying to find "foo" in PATH,
--   being able to override its location, etc.
--   
--   There's also a hook for adding programs in a Setup.lhs script. See
--   hookedPrograms in <a>UserHooks</a>. This gives a hook user the ability
--   to get the above flags and such so that they don't have to write all
--   the PATH logic inside Setup.lhs.
module Distribution.Simple.Program

-- | The simple name of the program, eg. ghc
[programName] :: Program -> String

-- | A function to search for the program if its location was not specified
--   by the user. Usually this will just be a call to
--   <a>findProgramOnSearchPath</a>.
--   
--   It is supplied with the prevailing search path which will typically
--   just be used as-is, but can be extended or ignored as needed.

-- | Try to find the version of the program. For many programs this is not

[programFindVersion] :: Program -> Verbosity -> FilePath -> IO (Maybe Version)

-- | A function to do any additional configuration after we have located
--   the program (and perhaps identified its version). For example it could
--   add args, or environment vars.
[programPostConf] :: Program -> Verbosity -> ConfiguredProgram -> IO ConfiguredProgram

-- | A function that filters any arguments that don't impact the output
--   from a commandline. Used to limit the volatility of dependency hashes
--   when using new-build.
[programNormaliseArgs] :: Program -> Maybe Version -> PackageDescription -> [String] -> [String]

-- | A search path to use when locating executables. This is analogous to

--   to use the system default method for finding executables
--   (<a>findExecutable</a> which on unix is simply looking on the
--   <tt>$PATH</tt> but on win32 is a bit more complicated).
--   
--   The default to use is <tt>[ProgSearchPathDefault]</tt> but you can add

-- | 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 <tt>configure</tt>,
--   <tt>build</tt> etc) it defines a type that holds all the flags, the
--   default set of flags and a <a>CommandUI</a> that maps command line
--   flags to and from the corresponding flags type.
--   
--   All the flags types are instances of <a>Monoid</a>, see
--   <a>http://www.haskell.org/pipermail/cabal-devel/2007-December/001509.html</a>
--   for an explanation.
--   
--   The types defined here get used in the front end and especially in
--   <tt>cabal-install</tt> 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.

-- | 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.

-- | 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
--   <tt>make</tt> program. All the commands just end up calling
--   <tt>make</tt> 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 <a>Distribution.Simple.Setup</a> 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:
--   
--   <ul>
--   <li><i>ConfigCmd</i> We assume the configure script accepts
--   <tt>--with-hc</tt>, <tt>--with-hc-pkg</tt>, <tt>--prefix</tt>,
--   <tt>--bindir</tt>, <tt>--libdir</tt>, <tt>--libexecdir</tt>,
--   <tt>--datadir</tt>.</li>
--   <li><i>BuildCmd</i> We assume that the default Makefile target will
--   build everything.</li>
--   <li><i>InstallCmd</i> We assume there is an <tt>install</tt> target.
--   Note that we assume that this does *not* register the package!</li>
--   <li><i>CopyCmd</i> We assume there is a <tt>copy</tt> target, and a
--   variable <tt>$(destdir)</tt>. The <tt>copy</tt> target should probably
--   just invoke <tt>make install</tt> recursively (e.g. <tt>$(MAKE)
--   install prefix=$(destdir)/$(prefix) bindir=$(destdir)/$(bindir)</tt>.
--   The reason we can't invoke <tt>make install</tt> directly here is that
--   we don't know the value of <tt>$(prefix)</tt>.</li>
--   <li><i>SDistCmd</i> We assume there is a <tt>dist</tt> target.</li>
--   <li><i>RegisterCmd</i> We assume there is a <tt>register</tt> target
--   and a variable <tt>$(user)</tt>.</li>
--   <li><i>UnregisterCmd</i> We assume there is an <tt>unregister</tt>
--   target.</li>
--   <li><i>HaddockCmd</i> We assume there is a <tt>docs</tt> or
--   <tt>doc</tt> target.</li>

-- | 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 slighly 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.

module Distribution.Simple.PackageIndex

-- | The default package index which contains
--   <tt>InstalledPackageInfo</tt>. Normally use this.
type InstalledPackageIndex = PackageIndex InstalledPackageInfo

-- | The collection of information about packages from one or more
--   <tt>PackageDB</tt>s. These packages generally should have an instance
--   of <a>PackageInstalled</a>
--   
--   Packages are uniquely identified in by their <a>UnitId</a>, they can
--   also be efficiently looked up by package name or by name and version.
data PackageIndex a

-- | Build an index out of a bunch of packages.
--   
--   If there are duplicates by <a>UnitId</a> then later ones mask earlier
--   ones.
fromList :: [InstalledPackageInfo] -> InstalledPackageIndex

-- | Merge two indexes.
--   
--   Packages from the second mask packages from the first if they have the
--   exact same <a>UnitId</a>.
--   
--   For packages with the same source <a>PackageId</a>, packages from the
--   second are "preferred" over those from the first. Being preferred
--   means they are top result when we do a lookup by source
--   <a>PackageId</a>. This is the mechanism we use to prefer user packages
--   over global packages.
merge :: InstalledPackageIndex -> InstalledPackageIndex -> InstalledPackageIndex

-- | Inserts a single package into the index.
--   
--   This is equivalent to (but slightly quicker than) using <a>mappend</a>
--   or <a>merge</a> with a singleton index.
insert :: InstalledPackageInfo -> InstalledPackageIndex -> InstalledPackageIndex

-- | Removes a single installed package from the index.
deleteUnitId :: UnitId -> InstalledPackageIndex -> InstalledPackageIndex

-- | Removes all packages with this source <a>PackageId</a> from the index.
deleteSourcePackageId :: PackageId -> InstalledPackageIndex -> InstalledPackageIndex

-- | Removes all packages with this (case-sensitive) name from the index.
--   
--   NB: Does NOT delete internal libraries from this package.
deletePackageName :: PackageName -> InstalledPackageIndex -> InstalledPackageIndex

-- | Does a lookup by unit identifier.
--   
--   Since multiple package DBs mask each other by <a>UnitId</a>, then we
--   get back at most one package.
lookupUnitId :: PackageIndex a -> UnitId -> Maybe a

-- | Does a lookup by component identifier. In the absence of Backpack,
--   this is just a <a>lookupUnitId</a>.
lookupComponentId :: PackageIndex a -> ComponentId -> Maybe a

-- | Does a lookup by source package id (name &amp; version).
--   
--   There can be multiple installed packages with the same source
--   <a>PackageId</a> but different <a>UnitId</a>. They are returned in
--   order of preference, with the most preferred first.
lookupSourcePackageId :: PackageIndex a -> PackageId -> [a]

-- | Convenient alias of <a>lookupSourcePackageId</a>, but assuming only
--   one package per package ID.
lookupPackageId :: PackageIndex a -> PackageId -> Maybe a

-- | Does a lookup by source package name.
lookupPackageName :: PackageIndex a -> PackageName -> [(Version, [a])]

-- | Does a lookup by source package name and a range of versions.
--   
--   We get back any number of versions of the specified package name, all
--   satisfying the version range constraint.
--   
--   This does NOT work for internal dependencies, DO NOT use this function
--   on those; use <a>lookupInternalDependency</a> instead.
--   
--   INVARIANT: List of eligible <a>InstalledPackageInfo</a> is non-empty.
lookupDependency :: InstalledPackageIndex -> Dependency -> [(Version, [InstalledPackageInfo])]

-- | Does a lookup by source package name and a range of versions.
--   
--   We get back any number of versions of the specified package name, all
--   satisfying the version range constraint.
--   
--   INVARIANT: List of eligible <a>InstalledPackageInfo</a> is non-empty.
lookupInternalDependency :: InstalledPackageIndex -> Dependency -> Maybe UnqualComponentName -> [(Version, [InstalledPackageInfo])]

-- | Does a case-insensitive search by package name.
--   
--   If there is only one package that compares case-insensitively to this
--   name then the search is unambiguous and we get back all versions of
--   that package. If several match case-insensitively but one matches
--   exactly then it is also unambiguous.
--   
--   If however several match case-insensitively and none match exactly
--   then we have an ambiguous result, and we get back all the versions of
--   all the packages. The list of ambiguous results is split by exact
--   package name. So it is a non-empty list of non-empty lists.
searchByName :: PackageIndex a -> String -> SearchResult [a]
data SearchResult a
None :: SearchResult a
Unambiguous :: a -> SearchResult a
Ambiguous :: [a] -> SearchResult a

-- | Does a case-insensitive substring search by package name.
--   
--   That is, all packages that contain the given string in their name.
searchByNameSubstring :: PackageIndex a -> String -> [a]

-- | Get all the packages from the index.
allPackages :: PackageIndex a -> [a]

--   
--   (Doesn't include private libraries.)
allPackagesByName :: PackageIndex a -> [(PackageName, [a])]

--   (Doesn't include private libraries)
allPackagesBySourcePackageId :: HasUnitId a => PackageIndex a -> [(PackageId, [a])]

-- | Get all the packages from the index.
--   
--   They are grouped by source package id and library name.
--   
--   This DOES include internal libraries.
allPackagesBySourcePackageIdAndLibName :: HasUnitId a => PackageIndex a -> [((PackageId, Maybe UnqualComponentName), [a])]

-- | All packages that have immediate dependencies that are not in the
--   index.
--   
--   Returns such packages along with the dependencies that they're
--   missing.
brokenPackages :: PackageInstalled a => PackageIndex a -> [(a, [UnitId])]

-- | Tries to take the transitive closure of the package dependencies.
--   
--   If the transitive closure is complete then it returns that subset of
--   the index. Otherwise it returns the broken packages as in
--   <a>brokenPackages</a>.
--   
--   <ul>
--   <li>Note that if the result is <tt>Right []</tt> it is because at
--   least one of the original given <a>PackageId</a>s do not occur in the
--   index.</li>
--   </ul>
dependencyClosure :: InstalledPackageIndex -> [UnitId] -> Either InstalledPackageIndex [(InstalledPackageInfo, [UnitId])]

-- | Takes the transitive closure of the packages reverse dependencies.
--   
--   <ul>
--   <li>The given <a>PackageId</a>s must be in the index.</li>
--   </ul>
reverseDependencyClosure :: PackageInstalled a => PackageIndex a -> [UnitId] -> [a]
topologicalOrder :: PackageInstalled a => PackageIndex a -> [a]
reverseTopologicalOrder :: PackageInstalled a => PackageIndex a -> [a]

-- | Given a package index where we assume we want to use all the packages
--   (use <a>dependencyClosure</a> if you need to get such a index subset)
--   find out if the dependencies within it use consistent versions of each
--   package. Return all cases where multiple packages depend on different
--   versions of some other package.
--   
--   Each element in the result is a package name along with the packages
--   that depend on it and the versions they require. These are guaranteed
--   to be distinct.
dependencyInconsistencies :: InstalledPackageIndex -> [(DepUniqueKey, [(UnitId, [InstalledPackageInfo])])]

-- | Find if there are any cycles in the dependency graph. If there are no
--   cycles the result is <tt>[]</tt>.
--   
--   This actually computes the strongly connected components. So it gives
--   us a list of groups of packages where within each group they all
--   depend on each other, directly or indirectly.
dependencyCycles :: PackageInstalled a => PackageIndex a -> [[a]]

-- | Builds a graph of the package dependencies.
--   
--   Dependencies on other packages that are not in the index are
--   discarded. You can check if there are any such dependencies with
--   <a>brokenPackages</a>.
dependencyGraph :: PackageInstalled a => PackageIndex a -> (Graph, Vertex -> a, UnitId -> Maybe Vertex)

-- | A rough approximation of GHC's module finder, takes a

-- | The installation directories in terms of <a>PathTemplate</a>s that

--   
--   A few of these installation directories are split into two components,

--   with other Unix build systems which also support <tt>--libdir</tt> and
--   <tt>--datadir</tt>. We would like users to be able to configure

--   the same package for multiple compilers we append the libsubdir to
--   get: <tt>/usr/lib64/$libname/$compiler</tt>.

-- | This has code for checking for various problems in packages. There is
--   one set of checks that just looks at a <a>PackageDescription</a> in
--   isolation and another set of checks that also looks at files in the
--   package. Some of the checks are basic sanity checks, others are
--   portability standards that we'd like to encourage. There is a
--   <a>PackageCheck</a> type that distinguishes the different kinds of
--   check so we can see which ones are appropriate to report in different
--   situations. This code gets uses when configuring a package when we
--   consider only basic problems. The higher standard is uses when when
--   preparing a source tarball and by Hackage when uploading new packages.
--   The reason for this is that we want to hold packages that are expected
--   to be distributed to a higher standard than packages that are only
--   ever expected to be used on the author's own environment.

PackageBuildImpossible :: String -> PackageCheck
[explanation] :: PackageCheck -> String

PackageBuildWarning :: String -> PackageCheck
[explanation] :: PackageCheck -> String

-- | An issue that might not be a problem for the package author but might

-- | This is a fairly large module. It contains most of the GHC-specific
--   code for configuring, building and installing packages. It also
--   exports a function for finding out what packages are already
--   installed. Configuring involves finding the <tt>ghc</tt> and
--   <tt>ghc-pkg</tt> programs, finding what language extensions this
--   version of ghc supports and returning a <a>Compiler</a> value.
--   
--   <a>getInstalledPackages</a> involves calling the <tt>ghc-pkg</tt>
--   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 <tt>-split-objs</tt> feature. We
--   have to compile any C files using ghc. Linking, especially for
--   <tt>split-objs</tt> is remarkably complex, partly because there tend
--   to be 1,000's of <tt>.o</tt> files and this can often be more than we
--   can pass to the <tt>ld</tt> or <tt>ar</tt> 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.

-- | 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 <tt>ghc-pkg</tt>. 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.

--   <tt>cpphs</tt>, <tt>c2hs</tt>, <tt>hsc2hs</tt>, <tt>happy</tt>,
--   <tt>alex</tt> etc and lists them in <a>knownSuffixHandlers</a>. On top
--   of this it provides a function for actually preprocessing some sources
--   given a bunch of known suffix handlers. This module is not as good as
--   it could be, it could really do with a rewrite to address some of the
--   problems we have with pre-processors.

-- | Convenience function; get the suffixes of these preprocessors.
ppSuffixes :: [PPSuffixHandler] -> [String]

-- | A preprocessor for turning non-Haskell files with the given extension
--   into plain Haskell source files.
type PPSuffixHandler = (String, BuildInfo -> LocalBuildInfo -> ComponentLocalBuildInfo -> PreProcessor)

-- | 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:
--   
--   <pre>
--   ppTestHandler :: PreProcessor
--   ppTestHandler =
--     PreProcessor {
--       platformIndependent = True,
--       runPreProcessor = mkSimplePreProcessor $ \inFile outFile verbosity -&gt;
--         do info verbosity (inFile++" has been preprocessed to "++outFile)
--            stuff &lt;- readFile inFile
--            writeFile outFile ("-- preprocessed as a test\n\n" ++ stuff)
--            return ExitSuccess
--   </pre>
--   
--   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 <tt>Setup.hs</tt> scripts can use to

--   are defined in <a>Distribution.Simple</a>. The <a>UserHooks</a> is a

--   
--   This hooks type is widely agreed to not be the right solution. Partly
--   this is because changes to it usually break custom <tt>Setup.hs</tt>

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):
--   
--   <ol>
--   <li>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.</li>
--   <li>In GHC 7.8, the string had to be a valid package identifier like
--   foo-0.1.</li>
--   </ol>
--   
--   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:
--   
--   <ul>
--   <li>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
--   <a>computeCompatPackageName</a> for more details.</li>
--   </ul>
--   
--   The mapping for GHC 7.10:
--   
--   <ul>
--   <li>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
--   <a>ABCDEF</a>. (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 <a>computeComponentId</a> are
--   guaranteed to have this form.If it is not of this form, we rehash the
--   IPID into the correct form and pass that.</li>
--   <li>For sub-components, we rehash the IPID into the correct format and
--   pass that.</li>
--   </ul>
computeCompatPackageKey :: Compiler -> MungedPackageName -> Version -> UnitId -> String

-- | Computes the package name for a library. If this is the public
--   library, it will just be the original package name; otherwise, it will
--   be a munged package name recording the original package name as well
--   as the name of the internal library.
--   
--   A lot of tooling in the Haskell ecosystem assumes that if something is
--   installed to the package database with the package name <tt>foo</tt>,
--   then it actually is an entry for the (only public) library in package
--   <tt>foo</tt>. With internal packages, this is not necessarily true: a
--   public library as well as arbitrarily many internal libraries may come
--   from the same package. To prevent tools from getting confused in this
--   case, the package name of these internal libraries is munged so that
--   they do not conflict the public library proper. A particular case
--   where this matters is ghc-pkg: if we don't munge the package name, the
--   inplace registration will OVERRIDE a different internal library.
--   
--   We munge into a reserved namespace, "z-", and encode both the
--   component name and the package name of an internal library using the
--   following format:
--   
--   compat-pkg-name ::= "z-" package-name "-z-" library-name
--   
--   where package-name and library-name have "-" ( "z" + ) "-" segments
--   encoded by adding an extra "z".
--   
--   When we have the public library, the compat-pkg-name is just the
--   package-name, no surprises there!
