languages system tag list to the language subtags of the BCP 47 language
subtag registry, with some manual adjustments. The mappings are
supplemented with macrolanguages' sublanguages and retired codes'
replacements, according to BCP 47 and some manual additions where BCP 47
omits a retired code entirely.
Also generated is a function, ``hb_ot_ambiguous_tag_to_language``,
intended for use by ``hb_ot_tag_to_language``. It maps OpenType tags
back to BCP 47 tags. Ambiguous OpenType tags (those that correspond to
multiple BCP 47 tags) are listed here, except when the alphabetically
first BCP 47 tag happens to be the chosen disambiguated tag. In that
case, the fallback behavior will choose the right tag anyway.

Regarding these various memory-modes:
- In no case shall the HarfBuzz client modify memory
that is passed to HarfBuzz in a blob. If there is
any such possibility, @HB_MEMORY_MODE_DUPLICATE should be used
such that HarfBuzz makes a copy immediately,
- Use @HB_MEMORY_MODE_READONLY otherwise, unless you really really
really know what you are doing,
- @HB_MEMORY_MODE_WRITABLE is appropriate if you really made a
copy of data solely for the purpose of passing to
HarfBuzz and doing that just once (no reuse!),
- If the font is mmap()ed, it's okay to use
@HB_MEMORY_MODE_READONLY_MAY_MAKE_WRITABLE, however, using that mode
correctly is very tricky. Use @HB_MEMORY_MODE_READONLY instead.

@short_description: Input and output buffers
@include: hb.h
Buffers serve a dual role in HarfBuzz; before shaping, they hold
the input characters that are passed to hb_shape(), and after
shaping they hold the output glyphs.
The input buffer is a sequence of Unicode codepoints, with
associated attributes such as direction and script. The output
buffer is a sequence of glyphs, with associated attributes such
as position and cluster.
|
58609 |
| hb-buffer.h |
hb_glyph_info_t:
@codepoint: either a Unicode code point (before shaping) or a glyph index
(after shaping).
@cluster: the index of the character in the original text that corresponds
to this #hb_glyph_info_t, or whatever the client passes to
hb_buffer_add(). More than one #hb_glyph_info_t can have the same
@cluster value, if they resulted from the same character (e.g. one
to many glyph substitution), and when more than one character gets
merged in the same glyph (e.g. many to one glyph substitution) the
#hb_glyph_info_t will have the smallest cluster value of them.
By default some characters are merged into the same cluster
(e.g. combining marks have the same cluster as their bases)
even if they are separate glyphs, hb_buffer_set_cluster_level()
allow selecting more fine-grained cluster handling.
The #hb_glyph_info_t is the structure that holds information about the
glyphs and their relation to input text.

to store the key and the value.
The value is stored in the least significant bits of the integer.
The key is stored in the most significant bits of the integer.

@short_description: Font face objects
@include: hb.h
A font face is an object that represents a single face from within a
font family.
More precisely, a font face represents a single face in a binary font file.
Font faces are typically built from a binary blob and a face index.
Font faces are used to create fonts.
A font face can be created from a binary blob using hb_face_create().
The face index is used to select a face from a binary blob that contains
multiple faces. For example, a binary blob that contains both a regular
and a bold face can be used to create two font faces, one for each face
index.

@short_description: Font objects
@include: hb.h
Functions for working with font objects.
A font object represents a font face at a specific size and with
certain other parameters (pixels-per-em, points-per-em, variation
settings) specified. Font objects are created from font face
objects, and are used as input to hb_shape(), among other things.
Client programs can optionally pass in their own functions that
implement the basic, lower-level queries of font objects. This set
of font functions is defined by the virtual methods in
#hb_font_funcs_t.
HarfBuzz provides a built-in set of lightweight default
functions for each method in #hb_font_funcs_t.
The default font functions are implemented in terms of the
#hb_font_funcs_t methods of the parent font object. This allows
client programs to override only the methods they need to, and
otherwise inherit the parent font's implementation, if any.

Unified iterator object.
The goal of this template is to make the same iterator interface
available to all types, and make it very easy and compact to use.
hb_iter_tator objects are small, light-weight, objects that can be
copied by value. If the collection / object being iterated on
is writable, then the iterator returns lvalues, otherwise it
returns rvalues.
If iterator implementation implements operator!=, then it can be
used in range-based for loop. That already happens if the iterator
is random-access. Otherwise, the range-based for loop incurs
one traversal to find end(), which can be avoided if written
as a while-style for loop, or if iterator implements a faster
__end__() method. |

HIGHLEVEL DESIGN:
This file exports one main function: _hb_ot_shape_normalize().
This function closely reflects the Unicode Normalization Algorithm,
yet it's different.
Each shaper specifies whether it prefers decomposed (NFD) or composed (NFC).
The logic however tries to use whatever the font can support.
In general what happens is that: each grapheme is decomposed in a chain
of 1:2 decompositions, marks reordered, and then recomposed if desired,
so far it's like Unicode Normalization. However, the decomposition and
recomposition only happens if the font supports the resulting characters.
The goals are:
- Try to render all canonically equivalent strings similarly. To really
achieve this we have to always do the full decomposition and then
selectively recompose from there. It's kinda too expensive though, so
we skip some cases. For example, if composed is desired, we simply
don't touch 1-character clusters that are supported by the font, even
though their NFC may be different.
- When a font has a precomposed character for a sequence but the 'ccmp'
feature in the font is not adequate, use the precomposed character
which typically has better mark positioning.
- When a font does not support a combining mark, but supports it precomposed
with previous base, use that. This needs the itemizer to have this
knowledge too. We need to provide assistance to the itemizer.
- When a font does not support a character but supports its canonical
decomposition, well, use the decomposition.
- The shapers can customize the compose and decompose functions to
offload some of their requirements to the normalizer. For example, the
Indic shaper may want to disallow recomposing of two matras.

Glyph paint callbacks.
The callbacks assume that the caller maintains a stack
of current transforms, clips and intermediate surfaces,
as evidenced by the pairs of push/pop callbacks. The
push/pop calls will be properly nested, so it is fine
to store the different kinds of object on a single stack.
Not all callbacks are required for all kinds of glyphs.
For rendering COLRv0 or non-color outline glyphs, the
gradient callbacks are not needed, and the composite
callback only needs to handle simple alpha compositing
(#HB_PAINT_COMPOSITE_MODE_SRC_OVER).
The paint-image callback is only needed for glyphs
with image blobs in the CBDT, sbix or SVG tables.
The custom-palette-color callback is only necessary if
you want to override colors from the font palette with
custom colors.

Sanitize
=== Introduction ===
The sanitize machinery is at the core of our zero-cost font loading. We
mmap() font file into memory and create a blob out of it. Font subtables
are returned as a readonly sub-blob of the main font blob. These table
blobs are then sanitized before use, to ensure invalid memory access does
not happen. The toplevel sanitize API use is like, eg. to load the 'head'
table:
hb_blob_t *head_blob = hb_sanitize_context_t ().reference_table<OT::head> (face);
The blob then can be converted to a head table struct with:
const head *head_table = head_blob->as<head> ();
What the reference_table does is, to call hb_face_reference_table() to load
the table blob, sanitize it and return either the sanitized blob, or empty
blob if sanitization failed. The blob->as() function returns the null
object of its template type argument if the blob is empty. Otherwise, it
just casts the blob contents to the desired type.
Sanitizing a blob of data with a type T works as follows (with minor
simplification):
- Cast blob content to T*, call sanitize() method of it,
- If sanitize succeeded, return blob.
- Otherwise, if blob is not writable, try making it writable,
or copy if cannot be made writable in-place,
- Call sanitize() again. Return blob if sanitize succeeded.
- Return empty blob otherwise.
=== The sanitize() contract ===
The sanitize() method of each object type shall return true if it's safe to
call other methods of the object, and %false otherwise.
Note that what sanitize() checks for might align with what the specification
describes as valid table data, but does not have to be. In particular, we
do NOT want to be pedantic and concern ourselves with validity checks that
are irrelevant to our use of the table. On the contrary, we want to be
lenient with error handling and accept invalid data to the extent that it
does not impose extra burden on us.
Based on the sanitize contract, one can see that what we check for depends
on how we use the data in other table methods. Ie. if other table methods
assume that offsets do NOT point out of the table data block, then that's
something sanitize() must check for (GSUB/GPOS/GDEF/etc work this way). On
the other hand, if other methods do such checks themselves, then sanitize()
does not have to bother with them (glyf/local work this way). The choice
depends on the table structure and sanitize() performance. For example, to
check glyf/loca offsets in sanitize() would cost O(num-glyphs). We try hard
to avoid such costs during font loading. By postponing such checks to the
actual glyph loading, we reduce the sanitize cost to O(1) and total runtime
cost to O(used-glyphs). As such, this is preferred.
The same argument can be made re GSUB/GPOS/GDEF, but there, the table
structure is so complicated that by checking all offsets at sanitize() time,
we make the code much simpler in other methods, as offsets and referenced
objects do not need to be validated at each use site.

| hb-set-digest.hh |
The set-digests here implement various "filters" that support
"approximate member query". Conceptually these are like Bloom
Filter and Quotient Filter, however, much smaller, faster, and
designed to fit the requirements of our uses for glyph coverage
queries.
Our filters are highly accurate if the lookup covers fairly local
set of glyphs, but fully flooded and ineffective if coverage is
all over the place.
The way these are used is that the filter is first populated by
a lookup's or subtable's Coverage table(s), and then when we
want to apply the lookup or subtable to a glyph, before trying
to apply, we ask the filter if the glyph may be covered. If it's
not, we return early. We can also match a digest against another
digest.
We use these filters at three levels:
- If the digest for all the glyphs in the buffer as a whole
does not match the digest for the lookup, skip the lookup.
- For each glyph, if it doesn't match the lookup digest,
skip it.
- For each glyph, if it doesn't match the subtable digest,
skip it.
The main filter we use is a combination of three bits-pattern
filters. A bits-pattern filter checks a number of bits (5 or 6)
of the input number (glyph-id in this case) and checks whether
its pattern is amongst the patterns of any of the accepted values.

@short_description: Object representing a shaping plan
@include: hb.h
Shape plans are an internal mechanism. Each plan contains state
describing how HarfBuzz will shape a particular text segment, based on
the combination of segment properties and the capabilities in the
font face in use.
Shape plans are not used for shaping directly, but can be queried to
access certain information about how shaping will perform, given a set
of specific input parameters (script, language, direction, features,
etc.).
Most client programs will not need to deal with shape plans directly.

Shaping is the central operation of HarfBuzz. Shaping operates on buffers,
which are sequences of Unicode characters that use the same font and have
the same text direction, script, and language. After shaping the buffer
contains the output glyphs and their positions.

hb_style_tag_t:
@HB_STYLE_TAG_ITALIC: Used to vary between non-italic and italic.
A value of 0 can be interpreted as "Roman" (non-italic); a value of 1 can
be interpreted as (fully) italic.
@HB_STYLE_TAG_OPTICAL_SIZE: Used to vary design to suit different text sizes.
Non-zero. Values can be interpreted as text size, in points.
@HB_STYLE_TAG_SLANT_ANGLE: Used to vary between upright and slanted text. Values
must be greater than -90 and less than +90. Values can be interpreted as
the angle, in counter-clockwise degrees, of oblique slant from whatever the
designer considers to be upright for that font design. Typical right-leaning
Italic fonts have a negative slant angle (typically around -12)
@HB_STYLE_TAG_SLANT_RATIO: same as @HB_STYLE_TAG_SLANT_ANGLE expression as ratio.
Typical right-leaning Italic fonts have a positive slant ratio (typically around 0.2)
@HB_STYLE_TAG_WIDTH: Used to vary width of text from narrower to wider.
Non-zero. Values can be interpreted as a percentage of whatever the font
designer considers “normal width” for that font design.
@HB_STYLE_TAG_WEIGHT: Used to vary stroke thicknesses or other design details
to give variation from lighter to blacker. Values can be interpreted in direct
comparison to values for usWeightClass in the OS/2 table,
or the CSS font-weight property.

@short_description: Subsets font files.
@include: hb-subset.h
Subsetting reduces the codepoint coverage of font files and removes all data
that is no longer needed. A subset input describes the desired subset. The input is
provided along with a font to the subsetting operation. Output is a new font file
containing only the data specified in the input.
Currently most outline and bitmap tables are supported: glyf, CFF, CFF2, sbix,
COLR, and CBDT/CBLC. This also includes fonts with variable outlines via OpenType
variations. Notably EBDT/EBLC and SVG are not supported. Layout subsetting is supported
only for OpenType Layout tables (GSUB, GPOS, GDEF). Notably subsetting of graphite or AAT tables
is not yet supported.
Fonts with graphite or AAT tables may still be subsetted but will likely need to use the
retain glyph ids option and configure the subset to pass through the layout tables untouched.

Unicode functions are used to access Unicode character properties.
With these functions, client programs can query various properties from
the Unicode Character Database for any code point, such as General
Category (gc), Script (sc), Canonical Combining Class (ccc), etc.
Client programs can optionally pass in their own Unicode functions
that implement the same queries. The set of functions available is
defined by the virtual methods in #hb_unicode_funcs_t.
HarfBuzz provides built-in default functions for each method in

Compile wasm-micro-runtime with:
$ cmake -DWAMR_BUILD_MULTI_MODULE=1 -DWAMR_BUILD_REF_TYPES=1 -DWAMR_BUILD_FAST_JIT=1
$ make
If you manage to build a wasm shared module successfully and want to use it,
do the following:
- Add -DWAMR_BUILD_MULTI_MODULE=1 to your cmake build for wasm-micro-runtime,
- Remove the #define HB_WASM_NO_MODULES line below,
- Install your shared module with name ending in .wasm in
$(prefix)/$(libdir)/harfbuzz/wasm/
- Build your font's wasm code importing the shared modules with the desired
name. This can be done eg.: __attribute__((import_module("graphite2")))
before each symbol in the shared-module's headers.
- Try shaping your font and hope for the best...
I haven't been able to get this to work since emcc's support for shared libraries
requires support from the host that seems to be missing from wasm-micro-runtime?
