Strings Overview

The String type in Beef is a mutable object with an adjustable “small string optimization” buffer, which stores character data in UTF8. StringView is a Span<char8> pointer-and-length struct. By convention, methods take string input through a StringView argument, and methods that want to return string data take a String argument which is used to append string data to.

String literals within a workspace that have equal values are guaranteed to be pooled and will have equal object addresses, and the pointer to the null-terminated C string pointer obtained through the char8* cast operator or the CStr() method are guaranteed to have the equal addresses. Generated strings whose value matchs a literal are guarnteed to return that literal’s address when passed through String.Intern().

String str = "This is a string";
char8* cStr = "This is a C string";
String str2 = "This string contains\n Two lines";
String str3 = @"C:\Path\Literal\NoSlashing";
String str4 = 
    """
    Multiline string literal
        with a tabbed second line;
    """;
