The two monolithic XSD content/identity rules only satisfied the OpenAPIKit
validation idiom at the wrong granularity: no per-constraint removability,
no isolable failing/near-miss tests. Split them into 32 named rules, each
finding tagged at its origin and cached per XSDContext so the walk still
runs once per document (the #101 decision against duplicating XSD's
recursive type resolution still holds). Wired the streaming path's ID/IDREF
and identity checks through the same framework instead of calling the
validators imperatively, and added the unwrapAndLookup combinator the rule
already named as required.
Also includes the mandated repo-wide swiftformat/swiftlint pass.
Group @testable imports at the bottom, per public/rules-swift's swiftformat. A
behavior-preserving import-ordering reformat across 252 files (mostly tests).
--trailingclosures was deliberately not adopted (cosmetic, and swiftformat flags
it as caution-worthy).
Add EUC-TW for the whole-buffer and streaming decoders: ASCII, a two-byte
plane-1 pair, and a 0x8E four-byte plane selector plus a pair. CNS planes 1
and 2, which carry essentially all real-world EUC-TW text, are vendored from
the ICU euc-tw-2014 mapping (private-use fallbacks dropped); planes 3-15 are a
documented follow-up. Tested for plane 1 (two-byte and four-byte forms), plane
2, and streaming. The streaming method moved to its own file to stay under the
type-body cap.
Closes#108
The streaming decoder previously selected an encoding only from a byte-order
mark or the UTF sniff, so its single-byte and CJK decode paths were latent. It
now reads the encoding from the XML declaration (the libxml2 behavior) when
there is no BOM, activating those paths over an incremental byte source. Add
the streaming form of ISO-2022-JP, carrying the stateful mode across reads
(extracted to its own file to stay under the type-body cap). A test asserts
streaming agrees with whole-buffer decode for a single-byte (ISO-8859-1), a
CJK (Shift_JIS), and an ISO-2022-JP document.
Part of #108, #105
Add the WHATWG iso-2022-jp decoder, the first stateful encoding: escape
sequences switch between ASCII, JIS X 0201 Roman (yen, overline), JIS X 0201
katakana, and the JIS X 0208 plane, resolved through the shared jis0208 table
(no new data). Tested across all four modes, with the JIS X 0208 kanji
cross-checked against the EUC-JP decoder (same table, same pointer). EUC-TW and
the streaming form of ISO-2022-JP remain.
Part of #108, #105
Add the WHATWG big5 decoder over the vendored index-big5 (18,590 entries),
for both the whole-buffer and streaming decoders. A lead in 0x81-0xFE plus
a trail in 0x40-0x7E or 0xA1-0xFE resolves through the index, covering
Traditional Chinese and the HKSCS extensions including the astral CJK
ideographs. Four pointers decode to a base letter plus a combining mark.
Selected by the big5 / big5-hkscs declaration names.
Closes#103
Extend the GBK two-byte subset to full GB18030: a lead byte followed by
a digit opens a four-byte form whose pointer is mapped through the WHATWG
index-gb18030-ranges linear ranges, reaching the supplementary planes.
The 207 ranges are vendored verbatim. Wired into the whole-buffer and
streaming decoders and the encoding-name table (gb18030/gb-18030).
Closes#102
Decode UTF-32 (both byte orders, BOM or sniffed) and the single-byte encodings
ISO-8859-1 and Windows-1252, selected by the XML declaration's encoding name,
in addition to UTF-8 and UTF-16. The streaming byte path also handles UTF-32.
Standard library only, no Foundation. Closes#28. Reimplemented from the
documented encoding algorithms; no upstream code copied. 4 tests; 94 total.
Add PureXML.parse(pullingBytes:) and events(pullingBytes:) over an incremental
byte source (() -> UInt8?). StreamingDecoder detects the encoding from the
leading bytes, strips any BOM, and yields one scalar at a time as a Character,
so a byte stream is never fully buffered. UTF-8 (1 to 4 bytes) and UTF-16 (with
surrogate pairs) are decoded incrementally; invalid sequences become the Unicode
replacement character. Standard library only, no Foundation. Reimplemented from
the documented UTF decoding rules; no upstream code copied.
Add PureXML.parse(bytes:) and events(bytes:) for raw [UInt8] input. The encoding
is detected following the XML sniff order (BOM first, then the <? byte pattern,
defaulting to UTF-8) and decoded with the Swift standard library only, so the
package stays Foundation-free and portable. UTF-8 and UTF-16 (both byte orders,
with or without a BOM) are supported, the encoding set the XML spec requires.
Malformed input (odd-length UTF-16) raises ParseError.malformedEncoding.
PureXML.Parsing.InputEncoding.detect(_:) exposes the detector. The lint rule
optional_data_string_conversion is disabled because its suggested fix is a
Foundation API this package cannot use. Reimplemented from the documented XML
byte-detection algorithm; no upstream code copied.
