Most codepoints correspond to the intuitive notion of a -// "letter", which is more formally known as a "grapheme cluster". A grapheme -// cluster is roughly speaking the amount of text that your cursor moves over -// when you press the arrow key once. However, some codepoints act as modifiers -// on other codepoints. For example, U+0301 (COMBINING ACUTE ACCENT) can modify -// a letter like "e" to form "é". During normalization, this frequently -// resolves down to a single unicode codepoint, in this case, "é" resolves to -// the single codepoint U+00E9 (LATIN SMALL LETTER E WITH ACUTE). However, in -// some cases, multiple codepoints make up a grapheme cluster but *don't* -// normalize to a single codepoint. For example, LATIN SMALL LETTER E (U+0065) -// + COMBINING VERTICAL LINE BELOW (U+0329) combine to form an unusual glyph -// that is not used frequently enough to warrant its own unique codepoint (this -// is basically what Zalgo text is). -// -// There are a lot of benefits to storing unicode text with one grapheme -// cluster per index in a densely packed array instead of storing the text as -// variable-width UTF8-encoded bytes. It lets us have one canonical length for -// the text that can be precomputed and is meaningful to users. It lets us -// quickly get the Nth "letter" in the text. Substring slicing is fast. -// However, since not all grapheme clusters take up the same number of -// codepoints, we're faced with the problem of how to jam multiple codepoints -// into a single 32-bit slot. Inspired by Raku and MoarVM's approach, this -// implementation uses "synthetic graphemes" (in Raku's terms, Normal Form -// Graphemes, aka NFG). A synthetic grapheme is a negative 32-bit signed -// integer that represents a multi-codepoint grapheme cluster that has been -// encountered during the program's runtime. These clusters are stored in a -// lookup array and hash map so that we can rapidly convert between the -// synthetic grapheme integer ID and the unicode codepoints associated with it. -// Essentially, it's like we create a supplement to the unicode standard with -// things that would be nice if they had their own codepoint so things worked -// out nicely because we're using them right now, and we'll give them a -// negative number so it doesn't overlap with any real codepoints. -// -// Example 1: U+0048, U+00E9 AKA: LATIN CAPITAL LETTER H, LATIN SMALL LETTER E -// WITH ACUTE This would be stored as: (int32_t[]){0x48, 0xE9} Example 2: -// U+0048, U+0065, U+0309 AKA: LATIN CAPITAL LETTER H, LATIN SMALL LETTER E, -// COMBINING VERTICAL LINE BELOW This would be stored as: (int32_t[]){0x48, -2} -// Where -2 is used as a lookup in an array that holds the actual unicode -// codepoints: (ucs4_t[]){0x65, 0x0309} - -#include <assert.h> -#include <ctype.h> -#include <gc.h> -#include <printf.h> -#include <stdbool.h> -#include <stdint.h> -#include <stdlib.h> -#include <sys/param.h> - -#include <unicase.h> -#include <unictype.h> -#include <unigbrk.h> -#include <uniname.h> -#include <unistr.h> -#include <unistring/version.h> -#include <uniwidth.h> - -#include "arrays.h" -#include "integers.h" -#include "patterns.h" -#include "tables.h" -#include "text.h" - -// Use inline version of the siphash code for performance: -#include "siphash.h" -#include "siphash-internals.h" - -typedef struct { - ucs4_t main_codepoint;
