Description

List

alaList :: sep -> [a] -> List sep (Identity a) a #

alaList and alaList' are simply List, with additional phantom arguments to constraint the resulting type

>>> :t alaList VCat
alaList VCat :: [a] -> List VCat (Identity a) a

>>> :t alaList' FSep Token
alaList' FSep Token :: [String] -> List FSep Token String

alaList' :: sep -> (a -> b) -> [a] -> List sep b a #

More general version of alaList.

Modifiers

data CommaVCat #

Vertical list with commas. Displayed with vcat

Constructors

CommaVCat

data CommaFSep #

Paragraph fill list with commas. Displayed with fsep

Constructors

CommaFSep

data VCat #

Vertical list with optional commas. Displayed with vcat.

Constructors

Type

data List sep b a #

List separated with optional commas. Displayed with sep, arguments of type a are parsed and pretty-printed as b.

Instances

(Newtype b a, Sep sep, Pretty b) => Pretty (List sep b a) #
Instance details Methods pretty :: List sep b a -> Doc #
(Newtype b a, Sep sep, Parsec b) => Parsec (List sep b a) #
Instance details Methods parsec :: CabalParsing m => m (List sep b a) #
Newtype (List sep wrapper a) [a] #
Instance details Methods pack :: [a] -> List sep wrapper a # unpack :: List sep wrapper a -> [a] #

Version & License

newtype SpecVersion #

Version range or just version, i.e. cabal-version field.

There are few things to consider:

Starting with 2.2 the cabal-version field should be the first field in the file and only exact version is accepted. Therefore if we get e.g. >= 2.2, we fail. See https://github.com/haskell/cabal/issues/4899
