High level string and text processing library

VSS

A high level string and text processing library.

The objectives

The objectives of this project are

• To introduce a definite type that represents a string of Unicode characters and provides a handy set of operations.
• The API should be encoding independent and allows efficient implementations depending on platform/application and avoid extra encoding conversions, e.g. an UTF-8 internal representation for Gtk+ applications, UCS-2 for native Windows applications and UTF-16 for WebAssembly.
• Besides separating string API from in-memory data representation, it should separate string API from input/output stream representation.
• To provide a clear, well-defined semantic for iteration over string elements, such as unicode unit, grapheme cluster, etc.
• To avoid string element integer indexes, because this isn't necessarily constant time and could mislead about indexed element kind.
• To prefer safe results over raising exceptions where possible.

Warning: This is experimental work in progress, everything is subject to change. It may be or may be not part of GNATCOLL or standard Ada library in the future.

Note: Some Ada 2020 features are used in source code. This requires compiler that supports them.

Install

Build from sources

Prefered way to install is to download sources and run

make all install PREFIX=/path/to/install

Using alire

Or you can use alire library manager:

alr get --build vss

Then you can use it as dependency in the project file:

with "vss_text.gpr";

For use JSON streaming API:

with "vss_json.gpr";
