str_view

Pictured Above: Mocking up a mini grep program is easy with the right tools. Use mini_grep and any other sample programs as they arrive in the samples/ folder to test the utility and convenience of a str_view.

The str_view type is a simple, copyable, flexible, read only view of const char * data in C, modeled after std::string_view in C++. However, there are a few extra features including read-only tokenization and threeway comparison between plain const char * data and a str_view.

A str_view is a 16-byte struct and, due to this size, is treated throughout the interface as a copyable type. This is neither a trivially cheap nor excessively expensive type to copy. The intention of this library is to abstract away many sharp edges of working with C-strings to provide usage that "just works," not optimize for performance yet.

Install Instructions

This library offers a manual installation through the Releases page or a port installation through the vcpkg package manager.

See INSTALL.md file for instructions on how to install the str-view port through vcpkg or how to manually download, build, and install the library.

Interface

Read the str_view.h interface for the full API and documentation.

Status

This library is not yet version 1.0. To reach 1.0 I would like to implement the following.

• More robust suite of tests to detect Undefined Behavor common with string handling.
• Better documentation highlighting when I cannot protect the user from Undefined Behavior through programmer error.
• SIMD intrinsics. At the very least, SIMD implemented for the short string brute force searches is critical.

That being said, I have already found this library very helpful whenever I need to write C code. Please consider giving it a try.
