Main> interface Prelude.Show : Type -> Type
|
|
Things that have a canonical `String` representation.
|
|
A minimal implementation includes either `show` or `showPrec`.
|
|
Parameters: ty
|
|
Constructor: MkShow
|
|
Methods:
|
|
show : ty -> String
|
|
Convert a value to its `String` representation.
|
|
@ x the value to convert
|
|
showPrec : Prec -> ty -> String
|
|
Convert a value to its `String` representation in a certain precedence
|
|
context.
|
|
|
|
A value should produce parentheses around itself if and only if the given
|
|
precedence context is greater than or equal to the precedence of the
|
|
outermost operation represented in the produced `String`. *This is
|
|
different from Haskell*, which requires it to be strictly greater. `Open`
|
|
should thus always produce *no* outermost parens, `App` should always
|
|
produce outermost parens except on atomic values and those that provide
|
|
their own bracketing, like `Pair` and `List`.
|
|
@ d the precedence context.
|
|
@ x the value to convert
