longDescription = ''
|
|
Astring exposes an alternative String module for OCaml. This module tries
|
|
to balance minimality and expressiveness for basic, index-free, string
|
|
processing and provides types and functions for substrings, string sets
|
|
and string maps.
|
|
|
|
Remaining compatible with the OCaml String module is a non-goal.
|
|
The String module exposed by Astring has exception safe functions, removes
|
|
deprecated and rarely used functions, alters some signatures and names,
|
|
adds a few missing functions and fully exploits OCaml's newfound string
|
|
immutability.
