The TextShow classes
TextShow
class TextShow a where Source #
Conversion of values to Text. Because there are both strict and lazy Text
variants, the TextShow class deliberately avoids using Text in its functions.
Instead, showbPrec, showb, and showbList all return Builder, an
efficient intermediate form that can be converted to either kind of Text.
Builder is a Monoid, so it is useful to use the mappend (or <>) function
to combine Builders when creating TextShow instances. As an example:
import Data.Semigroup
import TextShow
data Example = Example Int Int
instance TextShow Example where
showb (Example i1 i2) = showb i1 <> showbSpace <> showb i2
If you do not want to create TextShow instances manually, you can alternatively
use the TextShow.TH module to automatically generate default TextShow
instances using Template Haskell, or the TextShow.Generic module to
quickly define TextShow instances using GHC.Generics.

Methods
Arguments
| :: Int | The operator precedence of the enclosing context (a number
from |
| -> a | The value to be converted to a |
| -> Builder |
Convert a value to a Builder with the given predence.
Since: 2
Converts a value to a strict Text. If you hand-define this, it should
satisfy:
showb=showbPrec0
Since: 2
Converts a list of values to a Builder. By default, this is defined as
'showbList = , but it can be overridden to allow
for specialized displaying of lists (e.g., lists of showbListWith showbChars).

Arguments
| :: Int | The operator precedence of the enclosing context (a number
from |
| -> a | The value to be converted to a strict |
| -> Text |
Converts a value to a strict Text with the given precedence. This
can be overridden for efficiency, but it should satisfy:
showtPrecp =toStrict.showtlPrecp
Since: 3
Converts a value to a strict Text. This can be overridden for
efficiency, but it should satisfy:
showt=showtPrec0showt=toStrict.showtl
The first equation is the default definition of showt.

Converts a list of values to a strict Text. This can be overridden for
efficiency, but it should satisfy:

showtlPrecp =toLazyText.showbPrecp
Since: 3
Converts a value to a lazy Text. This can be overridden for
efficiency, but it should satisfy:
showtl=showtlPrec0showtl=toLazyText.showb
The first equation is the default definition of showtl.

Builders
The Builder type
A Builder is an efficient way to build lazy Text values.
There are several functions for constructing builders, but only one
to inspect them: to extract any data, you have to turn them into
lazy Text values using toLazyText.
Internally, a builder constructs a lazy Text by filling arrays
piece by piece. As each buffer is filled, it is 'popped' off, to
become a new chunk of the resulting lazy Text. All this is
hidden from the user of the Builder.
