C++ library for Unicode Strings, with value semantics on reference-counted shared slices

strpp - StringPlusPlus - pronounced "strip"

A value-oriented character string library with reference-counting to manage shared slices

Features

• By-value semantics (use StrRef like int, no explicit allocation, pass by reference/pointer, etc)
• Copies and substrings (aka slices) are free (do not copy the data)
• Any StrRef may be mutated - it will safely make a private copy of any shared data
• Content sharing is thread-safe and SMP safe using atomic reference counting and garbage collection
• All strings are stored as UTF-8
• All references to individual characters are UCS4 (UTF-32, aka Runes)
• All string indexing is by character position not byte offsets
• String scanning and indexing is made efficient through the use of bookmarks

Example

// This example creates precisely three strings, but with four references
#include        
   
    
#include        "strpp.h"

void greet(StrVal greeting)
{
	StrVal  decorated = greeting + "! 🎉🍾\n";
	fputs(decorated.asUTF8(), stdout);
}

int main()
{
	StrVal  hello("Hello, world");

	greet(hello);
}
