// The goal here is to produce a set of tables that represent a category of code point properties for every code point.
|
||||
// The most naive method would be to generate a single table per category, each with one entry per code point. Each of
|
||||
// those tables would have a size of 0x10ffff though, which is a non-starter. Instead, we create a set of 2-stage lookup
|
||||
// tables per category.
|
||||
//
|
||||
// To do so, it's important to note that Unicode tends to organize code points with similar properties together. This
|
||||
// leads to long series of code points with identical properties. Therefore, if we divide the 0x10ffff code points into
|
||||
// fixed-size blocks, many of those blocks will also be identical.
|
||||
//
|
||||
// So we iterate over every code point, classifying each one for the category of interest. We represent a classification
|
||||
// as a list of booleans. We store the classification in the CodePointTables::unique_properties list for this category.
|
||||
// As the name implies, this list is de-duplicated; we store the index into this list in a separate list, which we call
|
||||
// a "block".
|
||||
//
|
||||
// As we iterate, we "pause" every BLOCK_SIZE code points to examine the block. If the block is unique so far, we extend
|
||||
// CodePointTables::stage2 with the entries of that block (so CodePointTables::stage2 is also a list of indices into
|
||||
// CodePointTables::unique_properties). We then append the index of the start of that block in CodePointTables::stage2
|
||||
// to CodePointTables::stage1.
|
||||
//
|
||||
// The value of BLOCK_SIZE is determined by CodePointTables::MSB_COUNT and CodePointTables::LSB_COUNT. We need 24 bits
|
||||
// to describe all code points; the blocks we create are based on splitting these bits into 2 segments. We currently use
|
||||
// a 16:8 bit split. So when perform a runtime lookup of a code point in the 2-stage tables, we:
|
||||
//
|
||||
// 1. Use most-significant 16 bits of the code point as the index into CodePointTables::stage1. That value is the
|
||||
// index into CodePointTables::stage2 of the start of the block that contains properties for this code point.
|
||||
//
|
||||
// 2. Add the least-significant 8 bits of the code point to that value, to use as the index into
|
||||
// CodePointTables::stage2. As described above, that value is the index into CodePointTables::unique_properties,
|
||||
// which contains the classification for this code point.
|
||||
//
|
||||
// Using the code point GeneralCategory as an example, we end up with a CodePointTables::stage1 with a size of ~4000,
|
||||
// a CodePointTables::stage2 with a size of ~40,000, and a CodePointTables::unique_properties with a size of ~30. So
|
||||
// this process reduces over 1 million entries (0x10ffff) to ~44,030.
