1. many :: Alternative f => f a -> f [a]

   Cabal-syntax	Distribution.Compat.Prelude

   No documentation available.

2. getAny :: Any -> Bool

   Cabal-syntax	Distribution.Compat.Semigroup

   No documentation available.

3. PcAnyVersion :: PkgconfigVersionRange

   Cabal-syntax	Distribution.Types.PkgconfigVersionRange

   No documentation available.

4. isAnyPkgconfigVersion :: PkgconfigVersionRange -> Bool

   Cabal-syntax	Distribution.Types.PkgconfigVersionRange

   TODO: this is not precise, but used only to prettify output.

5. isAnyVersion :: VersionRange -> Bool

   Cabal-syntax	Distribution.Types.VersionRange

   Does this VersionRange place any restriction on the Version or is it in fact equivalent to AnyVersion. Note this is a semantic check, not simply a syntactic check. So for example the following is True (for all v).

   isAnyVersion (EarlierVersion v `UnionVersionRanges` orLaterVersion v)
   

6. isAnyVersionLight :: VersionRange -> Bool

   Cabal-syntax	Distribution.Types.VersionRange

   No documentation available.

7. isAbsoluteOnAnyPlatform :: FilePath -> Bool

   Cabal-syntax	Distribution.Utils.Generic

   isAbsoluteOnAnyPlatform and isRelativeOnAnyPlatform are like isAbsolute and isRelative but have platform independent heuristics. The System.FilePath exists in two versions, 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.

8. isRelativeOnAnyPlatform :: FilePath -> Bool

   Cabal-syntax	Distribution.Utils.Generic

   isRelativeOnAnyPlatform = not . isAbsoluteOnAnyPlatform
   

9. isAnyVersion :: VersionRange -> Bool

   Cabal-syntax	Distribution.Version

   Does this VersionRange place any restriction on the Version or is it in fact equivalent to AnyVersion. Note this is a semantic check, not simply a syntactic check. So for example the following is True (for all v).

   isAnyVersion (EarlierVersion v `UnionVersionRanges` orLaterVersion v)
   

10. DeriveAnyClass :: KnownExtension

    Cabal-syntax	Language.Haskell.Extension

    Enable deriving for any class.
