Module documentation for 0.1.6

Data
- Data.Text
  - Data.Text.Short
    - Data.Text.Short.Partial
    - Data.Text.Short.Unsafe

Depends on 8 packages(full list with versions):

base, binary, bytestring, deepseq, ghc-prim, hashable, template-haskell, text

Used by 20 packages in nightly-2024-11-08(full list with versions):

This package provides the ShortText type which is suitable for keeping many short strings in memory. This is similiar to how ShortByteString relates to ByteString.

The main difference between Text and ShortText is that ShortText doesn't support zero-copy slicing (thereby saving 2 words), and, compared to text-1.*, that it uses UTF-8 instead of UTF-16 internally. Consequently, the memory footprint of a (boxed) ShortText value is 4 words (2 words when unboxed) plus the length of the UTF-8 encoded payload.

Changes

0.1.6

Drop support for GHC prior 8.6.5
Support GHC-9.10 (base-4.21)

0.1.5

text-2.0 support

0.1.4

Fix fromString for single character strings. https://github.com/haskell-hvr/text-short/issues/20
Add Template Haskell Lift ShortText instance.

0.1.3

Add Data ShortText instance
Define Typeable ShortText also for GHC 7.8 as well (NB: for GHC 7.10.3 and up Typeable instances are automatically defined even when not mentioned explicitly in a deriving clause)
Add equivalent verb Data.Text.split to Data.Text.Short API
```
split :: (Char -> Bool) -> ShortText -> [ShortText]
```

0.1.2

Add IsList ShortText and PrintfArg ShortText instances

Expose partial functions via new Data.Text.Short.Partial module

foldl1 :: (Char -> Char -> Char) -> ShortText -> Char
foldl1' :: (Char -> Char -> Char) -> ShortText -> Char
foldr1 :: (Char -> Char -> Char) -> ShortText -> Char
head :: ShortText -> Char
index :: ShortText -> Int -> Char
init :: ShortText -> ShortText
last :: ShortText -> Char
tail :: ShortText -> ShortText
