The array-range insert() overload checked that pos fits the current
value and that first/last share the same owning value, but never
verified that value is itself an array. Passing iterators from an
object, a primitive, or null handed value-initialized (singular)
std::vector iterators straight to array_t::insert(), which is
undefined behavior. Add the missing is_array() check, mirroring the
equivalent check already present in the object-range insert()
overload.

Splitting removed-key detection and common-key recursion into separate
passes (for the earlier lookup-count fix) changed the emitted patch's
op order: all "remove" ops now came before all recursive per-key diffs,
instead of interleaved in source's iteration order as the original
implementation did. This broke docs/mkdocs/docs/examples/diff.output's
exact-match CI check (ci_test_examples) even though the patch was still
semantically correct.
Defer "remove" emission into the same walk that does the recursive
diffs, so common keys and deleted keys are interleaved in source order
again, matching historical output.
While restructuring that walk, the reordering ("slow path") branch was
only emitting "remove" for keys common to both objects, never for keys
present in source but genuinely absent from target -- a key deleted
alongside an actual reorder would silently survive the patch. Fixed by
removing every source key in the slow path (both deleted and common
keys need removing there; common keys are then re-added in target's
order). Verified with a targeted reorder+deletion case and a fresh
20,000-case round-trip fuzz run (0 failures).

The previous fix for ordered_json member order re-derived common-key
order and suffix information with extra target.find()/source.find()
calls layered on top of the pre-existing removed/added-key passes,
instead of reusing those same passes. This roughly tripled the number
of map lookups per diff() call for every object, including plain
`json`, where the reordering path is never taken.
Piggyback the order tracking (and the "add" op construction for new
keys) onto the two passes the algorithm already needs to detect
removed/added keys, and walk the fast path's recursion in lockstep
with the precomputed common-key list instead of re-querying `target`.
This restores diff() to its pre-existing lookup count; benchmarked at
n=1000 keys, ordered_json::diff() was roughly 2x slower than baseline
before this change and is back within noise of baseline after it.

diff() compared source/target objects purely by key set, ignoring
relative member order. For ordered_json (insertion-ordered, vector-
backed object_t), two objects that differ only in member order are
unequal via operator==, but diff() never emitted any patch operation
to fix the order, so source.patch(diff(source, target)) == target
could fail to hold.
Fix by detecting when common keys appear in a different relative
order in source vs. target (or when a new key would need to land
somewhere other than the end), and in that case removing and
re-adding the affected keys in target's order, which relies on
patch()'s "add" op appending new keys at the end of an ordered_map.
For plain json (std::map-backed, always key-sorted iteration) this
is a no-op and the original minimal per-key diff path is unchanged.

Both overloads swapped the underlying container storage but never called
set_parents(), leaving elements moved into *this with stale m_parent

* Broaden JSON_HEDLEY_WARN_UNUSED_RESULT coverage to pure query functions
Add JSON_HEDLEY_WARN_UNUSED_RESULT to the unambiguous, const,
side-effect-free observer functions whose return value is the entire
purpose of the call:
- dump()
- type(), type_name()
- all is_* predicates (is_primitive, is_structured, is_null,
is_boolean, is_number, is_number_integer, is_number_unsigned,
is_number_float, is_object, is_array, is_string, is_binary,
is_discarded)
- empty(), size(), max_size()
- count(...) (both overloads) and contains(...) (all overloads,
including the deprecated json_pointer<BasicJsonType> overload)
This mirrors the direction the standard library has taken with
[[nodiscard]] on the analogous std::vector/std::map members, and
catches real bugs such as `j.empty();` (meant `j.clear();`) or
`j.contains(k);` with the result thrown away.
Deliberately out of scope (left for a separate, later policy
decision, per the issue): at(), value(), get*(), flatten(),
unflatten(), patch(), merge_patch(), begin()/end(), comparison
operators, erase(), and emplace().
Compiling the full test suite (tests/src/unit-*.cpp) with
-Wunused-result -Werror uncovered one real hit: a regression test in
unit-regression2.cpp called dump() purely to check it does not throw,
discarding the result. Fixed by explicitly casting to void, since the

* Reject JSON Patch move when from is a proper prefix of path
RFC 6902 (section 4.4) forbids "from" from being a proper prefix of
"path" for a "move" operation: "a location cannot be moved into one
of its children." "move" is implemented as remove-then-add with no
check for this. For object targets, the subsequent "add" happened to
throw as a side effect of resolving through the now-removed parent,
but for array targets, removing the "from" element shifts subsequent
indices, so "path" silently re-resolves to a different element and
the operation "succeeds" with a silently corrupted document.
Add a check, before performing the remove/add, for whether "from" is
a proper prefix of "path" at the reference-token level. This compares
json_pointer's already-unescaped reference_tokens vectors (basic_json
is a friend of json_pointer) rather than the raw pointer strings, so
that tokens containing escaped '/' or '~' characters are compared
correctly, and a token that merely looks like a string prefix (e.g.
"/ab" vs "/abc/x") is not mistaken for a pointer-token prefix. When
"from" is a proper prefix of "path", throw out_of_range.414.
Fixes#5397.

* Route hand-rolled diagnostic pragmas through Hedley
Several places in the library hand-roll compiler diagnostic suppression
with raw `#pragma`/`#ifdef __GNUC__`/`#ifdef __clang__` guards instead of
using the Hedley primitives already bundled and used elsewhere
(JSON_HEDLEY_DIAGNOSTIC_PUSH/POP, JSON_HEDLEY_PRAGMA, ...). Converted six
of the seven listed push/pop pairs to use those primitives instead of
raw `#pragma GCC diagnostic`/`#pragma clang diagnostic` text:
- include/nlohmann/json.hpp (~3770, ~3863): -Wfloat-equal
- include/nlohmann/detail/conversions/to_chars.hpp (~1078): -Wfloat-equal
- include/nlohmann/detail/output/binary_writer.hpp (~1844): -Wfloat-equal
- include/nlohmann/detail/iterators/iteration_proxy.hpp (~211): -Wmismatched-tags
- include/nlohmann/detail/exceptions.hpp (~36): -Wweak-vtables
iteration_proxy.hpp did not previously include macro_scope.hpp itself
(it only compiled because some other header included earlier in
json.hpp happened to pull macro_scope.hpp in first); it now includes it
directly like the other detail headers that use Hedley macros, so it is
self-contained.
Each push/pop pair now uses JSON_HEDLEY_DIAGNOSTIC_PUSH/POP
unconditionally (a no-op on compilers that don't need it) and wraps the
actual `#pragma ... diagnostic ignored` text in JSON_HEDLEY_PRAGMA so it
goes through Hedley's _Pragma()-based emission instead of a raw #pragma
line, while keeping the original `#ifdef __GNUC__` / `#if
defined(__clang__)` guard around the ignored-pragma itself.
Deviation from the issue's suggested transformation: the issue's example
replaces the `#ifdef __GNUC__` guard with `#if
JSON_HEDLEY_HAS_WARNING("-Wfloat-equal")`. JSON_HEDLEY_HAS_WARNING is
implemented purely via Clang's `__has_warning` builtin and evaluates to
0 on real GCC (`#define JSON_HEDLEY_HAS_WARNING(warning) (0)` when
`__has_warning` is not defined), so adopting it verbatim would silently
stop suppressing -Wfloat-equal on GCC -- a real regression, not just a
style change. The existing `#ifdef __GNUC__` / `#if defined(__clang__)`
guards were kept for the ignored-pragma to stay behavior-preserving, and
only the push/pop/pragma-emission mechanism was routed through Hedley.
Two of the seven locations from the issue (the -Wignored-attributes
push at the very top of json.hpp and its matching pop after
`#include <nlohmann/detail/macro_unscope.hpp>`) were intentionally left
unconverted:
- The push, at the very top of json.hpp, runs before
`detail/macro_scope.hpp` (and therefore hedley.hpp) has been included
anywhere in the translation unit, so JSON_HEDLEY_DIAGNOSTIC_PUSH is not
yet defined at that point.
- The pop runs after `macro_unscope.hpp`, which -- via hedley_undef.hpp
-- has already #undef'd every JSON_HEDLEY_* macro (by design, see
#5408) precisely so they don't leak to users, so JSON_HEDLEY_DIAGNOSTIC_POP
is no longer defined by the time the pop is reached either.
Making this one pair work would require either hoisting the ~2000
line vendored hedley.hpp to the very top of the amalgamated single
header (a much bigger structural change to single_include than a pure
mechanism swap) or special-casing this one pop ahead of the general
macro cleanup. Both are riskier than the mechanical, behavior-preserving
change requested, so this pair was left as-is.
## Validation
- Compiled include/nlohmann/json.hpp and single_include/nlohmann/json.hpp
with `-Wall -Wextra -Wfloat-equal -Wmismatched-tags -Wweak-vtables`
(clang, which self-identifies as __GNUC__ too): no warnings, same as
before the change.
- Compiled and ran tests/src/unit-to_chars.cpp, unit-conversions.cpp,
unit-iterators1.cpp, unit-iterators2.cpp, and unit-class_parser.cpp
against the fixed include/: all pass.
- Compiled unit-msgpack.cpp, unit-bjdata.cpp, and unit-ubjson.cpp (which
exercise binary_writer.hpp's write_compact_float extensively): all
compile cleanly; the vast majority of assertions pass (the only
failures are pre-existing environment issues unrelated to this change
-- missing generated test-data files, not code correctness).
- Ran `make amalgamate`; the single_include diff is limited to exactly
the lines touched in include/, with no unrelated reordering.
- No real (non-Apple) GCC was available in this environment to test
directly; the `_Pragma("GCC diagnostic ...")` text emitted by
JSON_HEDLEY_PRAGMA is byte-identical to the prior `#pragma GCC
diagnostic ...` text, and the `#ifdef __GNUC__` guard is unchanged, so
GCC's behavior is expected to be identical. CI covers the GCC matrix.
This PR is stacked on top of #5475 (issue-5408-hedley-undef-leak) since
both touch the same files; only the last commit here is new.

unconditionally accepted), so scan_number() can skip strtoull()/
strtoll() entirely in that case when the caller signals it does not

The mixed number arms of JSON_IMPLEMENT_OPERATOR cast the integer to
number_float_t before comparing. Past the float's mantissa that cast is lossy:
2^63-2 and 2^63-1 both round to 2^63, so each compares equal to that float
while differing from each other. Equality is therefore intransitive and the
ordering is not a strict weak ordering, which makes std::sort over such values,
or using them as keys in std::set or std::map, undefined behavior.
Compare the two exactly instead. The integer's range is a power of two the
float represents exactly, so a float outside it is ordered by magnitude alone;
inside it, truncating the float is exact, and the integer parts and then any
fractional part decide. The helper hands back a pair whose comparison with the
original operator reproduces that ordering, which keeps every operator's return
type as it was, including partial_ordering for the spaceship.
A NaN operand is returned in both members, so NaN stays false for the
relational operators and unordered for <=>. Values a float represents exactly
still compare equal, so json(1) == json(1.0) is unchanged.

detail::input_adapter() free functions.
- Fix a latent ambiguity: some compilers (e.g. GCC 4.8) unreliably SFINAE
the operator!= detection for std::nullptr_t against container/string
types, making calls like parse(s, nullptr, ...) ambiguous with the
compatible-input overload. can_compare_ne now explicitly excludes
std::nullptr_t as a SentinelType.
- Use a named enable_if_t template parameter instead of an unnamed
function parameter for the SFINAE guard, fixing a clang-tidy
hicpp-named-parameter/readability-named-parameter failure.
- Update parse.md, accept.md, sax_parse.md, and the five from_*.md pages
to document the merged overload instead of separate (2)/(3) overloads,
also fixing an over-160-char line that broke the documentation
style_check CI job.

Fix by removing the hand-written operator!=, allowing the compiler to

and pre-C++20 friend functions).
Behavior change: operator!= now returns !(a==b) unconditionally, including
for special values like NaN and discarded. This means:
- NaN != NaN now returns true (matches IEEE-754 semantics)
- discarded != x now returns true for any x (matches !(discarded == x))
This also fixes underlying defects in previously-working code:
- Restores direct == comparison for views vs json (reverts std::ranges::equal
workaround added in PR #3950 to dodge this bug)
- Re-enables std::string == json comparisons (uncomments check in

When iteration_proxy_value<iter_impl<ordered_json>> appears in a context

* fix: treat single-element brace-init as copy/move
When passing a json value using brace initialization with a single element
(e.g., `json j{someObj}` or `foo({someJson})`), C++ always prefers the
initializer_list constructor over the copy/move constructor. This caused
the value to be unexpectedly wrapped in a single-element array.
This bug was previously compiler-dependent (GCC wrapped, Clang did not),
but Clang 20 started matching GCC behavior, making it a universal issue.
Fix: In the initializer_list constructor, when type deduction is enabled
and the list has exactly one element, copy/move it directly instead of
creating a single-element array.
Before:
json obj = {{"key", 1}};
json j{obj}; // -> [{"key":1}] (wrong: array)
foo({obj}); // -> [{"key":1}] (wrong: array)
After:
json j{obj}; // -> {"key":1} (correct: copy)
foo({obj}); // -> {"key":1} (correct: copy)
To explicitly create a single-element array, use json::array({value}).

PR #4873 introduced a safety check in sax_parse functions to catch

Compilers (e.g. clang) which respected the non-null annotation tended to
eliminate the safety check completely in optimized builds, while
compilers which did not, compiled the safety check in. This led to
different behaviors accross different compilers/platforms and/or build
types (debug, release).
