# Oniguruma source subset
This directory contains the Oniguruma sources needed by sd.cpp's
[UTF-8 regex wrapper](../../src/core/regex.cpp).
## Upstream source
- Repository: [kkos/oniguruma](https://github.com/kkos/oniguruma)
- Release: `v6.9.10`
- Commit: [`4ef89209a239c1aea328cf13c05a2807e5c146d1`](https://github.com/kkos/oniguruma/tree/4ef89209a239c1aea328cf13c05a2807e5c146d1)
- License: [BSD-2-Clause](COPYING)
The 24 upstream files below were copied without local modifications. `COPYING`
comes from the upstream repository root; all other files come from upstream
`src/` and retain their original filenames, flattened into this directory.
This README is maintained by sd.cpp and is not part of the upstream copy.
## File selection
The following 13 C files are compiled separately:
```text
ascii.c
regcomp.c
regenc.c
regerror.c
regexec.c
regparse.c
st.c
unicode.c
unicode_fold1_key.c
unicode_fold2_key.c
unicode_fold3_key.c
unicode_unfold_key.c
utf8.c
```
Four Unicode data tables are included by `unicode.c` and must not be compiled
as separate translation units. They were copied from upstream as supplied;
sd.cpp does not regenerate them:
```text
unicode_fold_data.c
unicode_property_data.c
unicode_egcb_data.c
unicode_wb_data.c
```
The remaining files are five headers, the platform configuration template,
and the license:
```text
oniguruma.h
regint.h
regenc.h
regparse.h
st.h
config.h.cmake.in
COPYING
```
The wrapper uses `ONIG_ENCODING_UTF8` and `ONIG_SYNTAX_ONIGURUMA`. ASCII support
is also retained because the engine requires it for initialization and error
handling. Unicode property, case-folding, grapheme-cluster and word-boundary
support remain enabled as in upstream.
Other encodings, GNU/POSIX compatibility APIs, unused API implementations,
upstream tests, examples, build scripts and packaging files are omitted.
This subset supports sd.cpp's internal wrapper; it does not provide the full
Oniguruma API declared in `oniguruma.h`.
## Build integration
[The parent CMake file](../CMakeLists.txt) detects platform headers and type
sizes, then generates `config.h` from `config.h.cmake.in` in the build directory.
It builds the 13 C files as the `onig` OBJECT target with `ONIG_STATIC` and
position-independent code enabled. The resulting objects are included directly
in the sd.cpp static or shared library, with no separate Oniguruma library
required by consumers.
Keep all 24 upstream files under version control, including the Unicode tables,
configuration template and license. Generated `config.h` and build artifacts
belong in the build directory.
When refreshing this subset, copy the listed files from the selected upstream
revision, retain `COPYING`, and update the revision recorded here.
Recheck source dependencies and the CMake configuration, then validate the
regex wrapper and tokenizer output on supported platforms.

# utf8proc source subset
This directory contains the utf8proc sources used by sd.cpp's
[JSON tokenizer](../../src/tokenizers/json_tokenizer.cpp) for NFC normalization,
lowercase mapping, and UTF-8 decoding and encoding.
## Upstream source
- Repository: [JuliaStrings/utf8proc](https://github.com/JuliaStrings/utf8proc)
- Release: `v2.10.0`
- Commit: [`a1b99daa2a3393884220264c927a48ba1251a9c6`](https://github.com/JuliaStrings/utf8proc/tree/a1b99daa2a3393884220264c927a48ba1251a9c6)
- Unicode version: `16.0.0`
- License: [MIT and Unicode data licenses](LICENSE.md)
The following four files were copied from the upstream repository root without
local modifications. Their original filenames are preserved. This README is
maintained by sd.cpp and replaces the upstream README.
| File | Purpose |
| --- | --- |
| `utf8proc.c` | Library implementation; the only separately compiled C file. |
| `utf8proc.h` | Public declarations, types and version definitions. |
| `utf8proc_data.c` | Unicode data tables included by `utf8proc.c`. |
| `LICENSE.md` | Library and Unicode data license notices. |
The library implementation and Unicode tables are retained in full.
`utf8proc_data.c` is copied as supplied by upstream; sd.cpp does not regenerate
it or compile it as a separate translation unit. Upstream tests, benchmarks,
documentation, data-generation tools and build/packaging files are omitted.
## Build integration
[The parent CMake file](../CMakeLists.txt) compiles `utf8proc.c` as the
`sd-utf8proc` OBJECT target with `UTF8PROC_STATIC` and position-independent code
enabled. The object is included directly in the sd.cpp static or shared library,
with no separate utf8proc library required by consumers. The license is installed
alongside sd.cpp.
All four upstream files belong under version control. Build artifacts belong
in the build directory; this subset requires no generated configuration header.
When refreshing this subset, copy all four files from the same upstream revision
and retain `LICENSE.md`. Update the release, commit and Unicode version recorded
here. Recheck source dependencies and validate tokenizer normalization, lowercase
conversion and token IDs on supported platforms.

/**
* @mainpage
*
* utf8proc is a free/open-source (MIT/expat licensed) C library
* providing Unicode normalization, case-folding, and other operations
* for strings in the UTF-8 encoding, supporting up-to-date Unicode versions.
* See the utf8proc home page (http://julialang.org/utf8proc/)
* for downloads and other information, or the source code on github
* (https://github.com/JuliaLang/utf8proc).
*
* For the utf8proc API documentation, see: @ref utf8proc.h
*
* The features of utf8proc include:
*
* - Transformation of strings (utf8proc_map()) to:
* - decompose (@ref UTF8PROC_DECOMPOSE) or compose (@ref UTF8PROC_COMPOSE) Unicode combining characters (http://en.wikipedia.org/wiki/Combining_character)
* - canonicalize Unicode compatibility characters (@ref UTF8PROC_COMPAT)
* - strip "ignorable" (@ref UTF8PROC_IGNORE) characters, control characters (@ref UTF8PROC_STRIPCC), or combining characters such as accents (@ref UTF8PROC_STRIPMARK)
* - case-folding (@ref UTF8PROC_CASEFOLD)

* about 1,000 characters that can be the first character in a
* combining pair, and for most, there are only a handful for
* possible second characters.
*
* The combining table is stored as sparse matrix in the CSR
* (compressed sparse row) format. That is, it is stored as two
* arrays, `utf8proc_uint32_t utf8proc_combinations_second[]` and
* `utf8proc_uint32_t utf8proc_combinations_combined[]`. These
* contain the second combining characters and the combined
* character of every combining pair.
*
* - `comb_index`: Index into the combining table if this character
* is the first character in a combining pair, else 0x3ff
*
* - `comb_length`: Number of table entries for this first character
*
* - `comb_is_second`: As optimization we also record whether this
* character is the second combining character in any pair. If
* not, we can skip the table lookup.
*
* A table lookup starts from a given character pair. It first
* checks whether the first character is stored in the table
* (checking whether the index is 0x3ff) and whether the second
* index is stored in the table (looking at `comb_is_second`). If
* so, the `comb_length` table entries will be checked sequentially
