D10.Char

Description

Defines a D10 type as a newtype for Char, where the values are restricted to characters between '0' and '9'.

This module provides many functions for constructing D10 values, including:

With the QuasiQuotes GHC extension enabled, you can write D10 literals using the quasi-quoters d10 and d10list.

Show

show shows base-10 digits using the quasiquoters defined in this module. A single digit is displayed using d10. A list of digits is displayed using d10list.

Quasi-quoters

d10 :: QuasiQuoter Source #

A single base-10 digit.

This quasi-quoter, when used as an expression, produces a value of type D10.

>>> d10Nat [d10|5|]
5
>>> d10Nat [d10|a|]
...
... d10 must be between 0 and 9
...
>>> d10Nat [d10|58|]
...
... d10 must be a single character
...

This quasi-quoter can also be used as a pattern.

>>> :{
      case (charD10Maybe '5') of
        Just [d10|4|] -> "A"
        Just [d10|5|] -> "B"
        _             -> "C"
>>> :}
"B"
>>> :{
      case (charD10Maybe '5') of
        Just [d10|x|] -> "A"
        Just [d10|5|] -> "B"
        _             -> "C"
>>> :}
...
... d10 must be between 0 and 9
...

d10list :: QuasiQuoter Source #

A list of base-10 digits.

This quasi-quoter, when used as an expression, produces a value of type [D10].

>>> d10Nat <$> [d10list||]
[]
>>> d10Nat <$> [d10list|5|]
[5]
>>> d10Nat <$> [d10list|58|]
[5,8]
>>> d10Nat <$> [d10list|a|]
...
... d10 must be between 0 and 9
...

This quasi-quoter can also be used as a pattern.

>>> :{
      case [d10list|56|] of
        [d10list|41|] -> "A"
        [d10list|56|] -> "B"
        _             -> "C"
>>> :}
"B"
>>> :{
      case [d10list|56|] of
        [d10list|4x|] -> "A"
        [d10list|56|] -> "B"
        _             -> "C"
>>> :}
...
... d10 must be between 0 and 9
...

Splices

Expressions

d10Exp :: Integer -> Q Exp Source #

Produces an expression of type D10 that can be used in a Template Haskell splice.

>>> d10Nat $(d10Exp 5)
5
>>> d10Nat $(d10Exp 12)
...
... d10 must be between 0 and 9
...

You may also be interested in d10, a quasi-quoter which does something similar.

d10ListExp :: String -> Q Exp Source #

Produces an expression of type [D10] that can be used in a Template Haskell splice.

>>> d10Nat <$> $(d10ListExp "")
[]
>>> d10Nat <$> $(d10ListExp "5")
[5]
>>> d10Nat <$> $(d10ListExp "58")
[5,8]
>>> d10Nat <$> $(d10ListExp "a")
...
... d10 must be between 0 and 9
...

You may also be interested in d10list, a quasi-quoter which does something similar.

Patterns

d10Pat :: Integer -> Q Pat Source #

Produces a pattern that can be used in a splice to match a particular D10 value.

>>> :{
      case (charD10Maybe '5') of
        Just $(d10Pat 4) -> "A"
        Just $(d10Pat 5) -> "B"
        _                -> "C"
>>> :}
"B"

You may wish to use the d10 quasi-quoter instead.

d10ListPat :: String -> Q Pat Source #

Produces a pattern that can be used in a splice to match a particular list of D10 values.

>>> :{
      case (strD10ListMaybe "56") of
        Just $(d10ListPat "42") -> "A"
        Just $(d10ListPat "56") -> "B"
        _                       -> "C"
>>> :}
"B"

You may wish to use the d10list quasi-quoter instead.
