Parsec VersionRange Source #
>>> simpleParsec "^>= 3.4" :: Maybe VersionRange
Just (MajorBoundVersion (mkVersion [3,4]))

Small history:

-any and -none removed in 3.4 Use >=0 and <0 instead.

>>> map (`simpleParsec'` "-none") [CabalSpecV3_0, CabalSpecV3_4] :: [Maybe VersionRange]
[Just (EarlierVersion (mkVersion [0])),Nothing]

Set operations are introduced in 3.0

>>> map (`simpleParsec'` "^>= { 1.2 , 1.3 }") [CabalSpecV2_4, CabalSpecV3_0] :: [Maybe VersionRange]
[Nothing,Just (UnionVersionRanges (MajorBoundVersion (mkVersion [1,2])) (MajorBoundVersion (mkVersion [1,3])))]

^>= is introduced in 2.0

>>> map (`simpleParsec'` "^>=1.2") [CabalSpecV1_24, CabalSpecV2_0] :: [Maybe VersionRange]
[Nothing,Just (MajorBoundVersion (mkVersion [1,2]))]

-none is introduced in 1.22

>>> map (`simpleParsec'` "-none") [CabalSpecV1_20, CabalSpecV1_22] :: [Maybe VersionRange]
[Nothing,Just (EarlierVersion (mkVersion [0]))]

Operators are introduced in 1.8. Issues only a warning.

>>> map (`simpleParsecW'` "== 1 || ==2") [CabalSpecV1_6, CabalSpecV1_8] :: [Maybe VersionRange]
[Nothing,Just (UnionVersionRanges (ThisVersion (mkVersion [1])) (ThisVersion (mkVersion [2])))]

Wild-version ranges are introduced in 1.6. Issues only a warning.

>>> map (`simpleParsecW'` "== 1.2.*") [CabalSpecV1_4, CabalSpecV1_6] :: [Maybe VersionRange]
[Nothing,Just (IntersectVersionRanges (OrLaterVersion (mkVersion [1,2])) (EarlierVersion (mkVersion [1,3])))]

Constructing

anyVersion :: VersionRange Source #

The version range -any. That is, a version range containing all versions.

withinRange v anyVersion = True

noVersion :: VersionRange Source #

The empty version range -none, that is a version range containing no versions.

This can be constructed using any unsatisfiable version range expression, for example < 0.

withinRange v noVersion = False

thisVersion :: Version -> VersionRange Source #

The version range == v.

withinRange v' (thisVersion v) = v' == v

notThisVersion :: Version -> VersionRange Source #

The version range /= v.

withinRange v' (notThisVersion v) = v' /= v

laterVersion :: Version -> VersionRange Source #

The version range > v.

withinRange v' (laterVersion v) = v' > v

earlierVersion :: Version -> VersionRange Source #

The version range < v.

withinRange v' (earlierVersion v) = v' < v

orLaterVersion :: Version -> VersionRange Source #

The version range >= v.

withinRange v' (orLaterVersion v) = v' >= v

orEarlierVersion :: Version -> VersionRange Source #

The version range <= v.

withinRange v' (orEarlierVersion v) = v' <= v

unionVersionRanges :: VersionRange -> VersionRange -> VersionRange Source #

The version range vr1 || vr2.

  withinRange v' (unionVersionRanges vr1 vr2)
= withinRange v' vr1 || withinRange v' vr2

intersectVersionRanges :: VersionRange -> VersionRange -> VersionRange Source #

The version range vr1 && vr2.

  withinRange v' (intersectVersionRanges vr1 vr2)
= withinRange v' vr1 && withinRange v' vr2

withinVersion :: Version -> VersionRange Source #

The version range == v.*.

For example, for version 1.2, the version range == 1.2.* is the same as >= 1.2 && < 1.3.

withinRange v' (withinVersion v) = v' >= v && v' < upper v
  where
    upper (Version lower t) = Version (init lower ++ [last lower + 1]) t

majorBoundVersion :: Version -> VersionRange Source #

The version range ^>= v.

For example, for version 1.2.3.4, the version range ^>= 1.2.3.4 is the same as >= 1.2.3.4 && < 1.3.

Note that ^>= 1 is equivalent to >= 1 && < 1.1.

Since: Cabal-syntax-2.0.0.2

Inspection

withinRange :: Version -> VersionRange -> Bool Source #

Does this version fall within the given range?

This is the evaluation function for the VersionRange type.

foldVersionRange Source #

Arguments

:: a

"-any" version

-> (Version -> a)
"== v"
-> (Version -> a)
"> v"
-> (Version -> a)
"< v"
-> (a -> a -> a)

"_ || _" union

-> (a -> a -> a)

"_ && _" intersection

-> VersionRange 
-> a 

Fold over the basic syntactic structure of a VersionRange.

This provides a syntactic view of the expression defining the version range. The syntactic sugar ">= v", "<= v" and "== v.*" is presented in terms of the other basic syntax.

For a semantic view use asVersionIntervals.

normaliseVersionRange :: VersionRange -> VersionRange Source #

Normalise VersionRange.

In particular collapse (== v || > v) into >= v, and so on.

stripParensVersionRange :: VersionRange -> VersionRange Source #

Remove VersionRangeParens constructors.

Since version 3.4 this function is id, there aren't VersionRangeParens constructor in VersionRange anymore.

Since: Cabal-syntax-2.2

hasUpperBound :: VersionRange -> Bool Source #

Does the version range have an upper bound?

Since: Cabal-syntax-1.24.0.0

hasLowerBound :: VersionRange -> Bool Source #

Does the version range have an explicit lower bound?

Note: this function only considers the user-specified lower bounds, but not the implicit >=0 lower bound.

Utilities

isAnyVersion :: VersionRange -> Bool Source #

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)

wildcardUpperBound :: Version -> Version Source #

Increment the last version number.

Example: For 1.2 this returns 1.3 so that it can be used as upper bound when resolving == 1.2.*. For 0.4.1 it returns 0.4.2.

Since: Cabal-syntax-2.2

majorUpperBound :: Version -> Version Source #

Compute next greater major version to be used as upper bound.

Example: 0.4.1 produces the version 0.5 which then can be used to construct a range >= 0.4.1 && < 0.5

versionRangeParser :: CabalParsing m => m Int -> CabalSpecVersion -> m VersionRange Source #
