* Fix the ci_cmake_flags wiring so every option is checked
The CMake 3.31.6 flag list referred to itself before it was defined,
so only JSON_BuildTests was checked with that version. The targets for
the CMake running the build ("_2") were created but never added to
ci_cmake_flags, and the three versions shared one build directory.
JSON_StrictNulHandling was not in the list at all.
Use the 3.5.0 list for 3.31.6, add JSON_StrictNulHandling, and create
one ci_cmake_flag_<flag> target per option for the running CMake with
its own build directory. Also use the function parameter in the
COMMENT, refresh the stale version comment, and let ci_clean remove
the downloaded cmake-<version> directories instead of the long-gone
cmake-3.5.0-Darwin64.

* Fix ci_test_clang_libcxx_cxx* jobs silently building without warnings
CMake only seeds CMAKE_CXX_FLAGS from the CXXFLAGS environment variable
when the cache entry is unset, so the explicit -DCMAKE_CXX_FLAGS="-stdlib=libc++"
argument made it ignore CXXFLAGS="${CLANG_CXXFLAGS}" entirely. The six
ci_test_standards_clang (..., libcxx) jobs therefore compiled without
-Weverything/-Werror while their libstdc++ siblings did use them.
Pass -stdlib=libc++ through the same CXXFLAGS value instead of a separate
-D argument, and give the target its own build directory
(build_clang_libcxx_cxx${CXX_STANDARD}) so it no longer shares a CMake
cache with the libstdc++ variant. Suppress the resulting
-Wthread-safety-negative finding from libc++'s std::mutex annotations,
which fires on doctest's reporters in this translation unit only.

* Remove the no-op AppVeyor with_win_header job
The with_win_header matrix entry patched Windows.h into
single_include/nlohmann/json.hpp before building, but JSON_MultipleHeaders
has defaulted to ON since #3532 (2022-06), so CMakeLists.txt points the
tests at include/ and the patched single header is never compiled. The
job has been a no-op VS2015 build since then.
Windows.h coverage already exists through tests/src/unit-windows_h.cpp
(#3631), which runs in every MSVC job. Delete the dead matrix entry and
its before_build steps, and cite unit-windows_h.cpp from the QA page.

* Remove unused ci_oclint and ci_pvs_studio targets
No workflow invokes ci_oclint, ci_pvs_studio, or their tool discovery.
ci_oclint also had a side effect on every JSON_CI configure: it copied
the single header into src_single/all.cpp and added an add_executable()
for it without EXCLUDE_FROM_ALL, so a plain build compiled a 1.2 MB
translation unit that only that unused target consumed. ci_pvs_studio
duplicates the Makefile's pvs_studio target, which is kept.
Also drop the duplicate --check-level=exhaustive flag passed twice to
the same ci_cppcheck invocation.

* Make scan-build fail on findings and drop irrelevant checkers (#5715 item 4a)
ci_clang_analyze ran scan-build without --status-bugs, so the job
passed whenever the ninja build succeeded, no matter what the
analyzer found ("No bugs found" in a green run gave no signal either
way). It is also missing --use-analyzer=${CLANG_TOOL}, so scan-build
picks whichever clang happens to be first on PATH inside the
silkeh/clang:dev container instead of the one this file already
selected and versioned.
Add --status-bugs and --use-analyzer=${CLANG_TOOL} to the scan-build
invocation. While here, drop the osx.*, webkit.*, fuchsia.*, and
optin.mpi.* checkers from CLANG_ANALYZER_CHECKS: none of them apply
to this portable C++ library, and leaving them enabled only adds
noise once the job can actually fail on a finding.
The job is currently clean (0 bugs), so this alone does not surface
any new finding; it only makes the existing "no bugs found" result
authoritative. This is 4a of 3 independent steps in #5715 item 4;
4b (Infer) and 4c (IWYU) still need their existing findings triaged
before --fail-on-issue/-Xiwyu --error can be added, and are handled

* Deduplicate the amalgamation/format check's file set and add BUILD.bazel (#5715 item 5)
The amalgamation/format check existed three times with three different
file sets: the Makefile's pretty/check-amalgamation, the pull_request-only
check_amalgamation.yml workflow, and the ci_test_amalgamation CMake target
that also runs on direct pushes to develop/master/release/*. The CMake
target's glob was a strict subset of the workflow's (missing the
docs/mkdocs/docs/examples/*.hpp headers, tests/abi/, tests/cmake_*/project/,
tests/cuda_example/, tests/fmt_formatter/, and tests/module_cpp20/), and it
never checked BUILD.bazel at all, so a misformatted file in any of those
paths, or a stale BUILD.bazel, could reach develop through a direct push
even though the PR-only workflow would have caught it.
Make ci_test_amalgamation glob the same roots (docs/mkdocs/docs/examples,
include, tests) and extensions (*.hpp, *.cpp, *.cu) as check_amalgamation.yml,
excluding tests/thirdparty/ and tests/abi/include/nlohmann/ the same way, and
regenerate and diff BUILD.bazel next to json.hpp/json_fwd.hpp. Also add
docs/mkdocs/docs/examples/*.hpp to the Makefile's pretty/pretty_format
targets, which were missing the four custom_*_type.hpp example headers, and
drop the stale "called by Travis" comment on check-amalgamation (Travis is
gone; nothing currently calls that Makefile target from CI).
Leaves the workflow itself untouched: it deliberately runs amalgamate.py
from a fresh develop checkout so a PR cannot change the tool that checks it.
Overlaps #5610 and #5621, which each add a new amalgamated header and touch
the same INDENT_FILES/ci_test_amalgamation/check_amalgamation.yml hunks.
Verified with `make check-amalgamation` on this branch: clean, no diff.

* Download prebuilt CMake binaries on Linux x86_64 instead of building from source (#5715 item 6)
ci_get_cmake() downloaded the source tarball of CMake 3.5.0, 3.31.6, and
4.0.0 and compiled each one completely (including CMake's own test
helpers) with -DCMAKE_POLICY_VERSION_MINIMUM=3.5 as a workaround for
building old CMake with a newer one. On CI this made the
ci_cmake_options (ci_cmake_flags) job take about 11 minutes, most of it
spent building CMake itself, even though Kitware has published
ready-to-run Linux x86_64 archives for all three of these releases
since 3.20 (lowercase platform name).
On Linux x86_64, download and unpack the prebuilt
cmake-<version>-linux-x86_64.tar.gz archive instead and point the
existing ${var} output at its bin/cmake, skipping the configure/build
steps and CMAKE_POLICY_VERSION_MINIMUM entirely. Keep the previous
source build as a fallback for any other platform (macOS, Linux
aarch64), since Kitware does not publish binaries for every
CMake/platform combination this project might build on.
Verify the downloaded archive against Kitware's own published checksum
before unpacking it: download cmake-<version>-SHA-256.txt alongside the
archive and run `sha256sum -c` on the matching line. A CI job that wgets
and untars a binary from a release page with no integrity check is a
supply-chain gap; Kitware has published this file for every release
since 3.20, so checking it costs one extra download and one grep.
As a separate, mechanical change: the ci_cmake_options job's container
only needed to stay on ubuntu:focal for the source build's
libssl-dev dependency and its own aging toolchain; now that the
Linux/x86_64 path never compiles CMake, drop libssl-dev from its apt
install line and move the job to ubuntu:24.04 (Ubuntu 20.04 left
standard support in May 2025). ci_clean already removes the
cmake-3.5.0/cmake-3.31.6/cmake-4.0.0 directories from the #5715 item 3
fix, and the prebuilt path reuses those same directory names, so no
further cleanup changes are needed.
Overlaps #5598, which edits the same ci_cmake_options matrix line in
ubuntu.yml; a rebase may be needed once that lands.
Verified locally: `cmake -S . -B build -DJSON_CI=On` configures cleanly
on macOS/arm64 (source-build fallback branch) and on Linux/x86_64 in an
ubuntu:24.04 Docker container (47 `ci_cmake_flag_*` targets generated,
one built and run successfully); `.github/workflows/ubuntu.yml` still
parses as valid YAML; downloaded the real v3.31.6 Linux x86_64 archive
and SHA-256 file from Kitware and confirmed the `grep | sha256sum -c`
pipeline both accepts the genuine file and is anchored to the exact
filename (not a prefix match).
CI must confirm: the prebuilt-binary path actually runs on the
ubuntu-latest/ubuntu:24.04 x86_64 runner, all `ci_cmake_options`
entries still pass with the new container's GCC, and the job's
runtime drops from roughly 11 minutes.

* Make Infer fail on findings, with a type-level baseline for the ~174 pre-existing ones (#5715 item 4b)
ci_infer ran `infer run` without --fail-on-issue, so the job passed
regardless of what Pulse found; the last recorded run (35829411620,
commit 1054b2097) logged "Found 174 issues" and still went green.
report.txt was also never uploaded, so the full finding list was only
ever visible in the truncated 5-issue console excerpt.
Add a repository-root .inferconfig (auto-discovered by Infer; passing
--project-root on the `infer run` invocation makes sure it is found
even though the analysis runs from build/build_infer) that sets
fail-on-issue and disables the six PULSE issue types that made up all
174 findings in that run: PULSE_UNNECESSARY_COPY_ASSIGNMENT (129),
PULSE_UNNECESSARY_COPY (22), PULSE_UNNECESSARY_COPY_INTERMEDIATE (15),
PULSE_RESOURCE_LEAK (5), PULSE_CONST_REFABLE (2), and
PULSE_UNNECESSARY_COPY_OPTIONAL (1).
This is a deliberate, narrower fix than "triage and fix everything in
this PR": the visible sample is entirely doctest-macro copies in test
code (for example tests/src/unit-algorithms.cpp:141 and
tests/src/unit-bjdata.cpp:3706), but 169 of the 174 findings were never
uploaded anywhere and this PR cannot respectably claim to have fixed
issues it never saw, including the resource-leak and const-refable
ones that are the most likely to be genuine bugs. Disabling by issue
type is a coarser baseline than a per-finding one (Infer has no
built-in per-finding baseline short of the two-run `infer reportdiff`
workflow, which this repository does not have the CI infrastructure
for), but it has the same effect today: the job goes from always green
to green-only-when-clean-of-everything-else, so CI now fails the
moment a *new* issue type appears, and report.txt is uploaded as a
workflow artifact on every run (including failures) so the six
disabled types can be triaged and re-enabled incrementally in follow-up
PRs.
#5715 item 4b. 4a (scan-build) and 4c (IWYU) are handled in separate
commits.
Verified: .inferconfig parses as JSON, ubuntu.yml still parses as
YAML. Infer itself is not available in this environment (v1.3.0 tar.xz
requires a Linux x86_64 runner), so CI must confirm that `infer run
--project-root ... -- make` picks up .inferconfig, that fail-on-issue
takes effect, and that the six disabled types actually suppress the
existing findings without also hiding an unrelated new one.

* Fix IWYU findings for json.hpp/json_fwd.hpp/ordered_map.hpp and make CI fail on new ones (#5715 item 4c)
ci_single_binaries ran IWYU via CMake's CXX_INCLUDE_WHAT_YOU_USE launcher
property, which only printed "Warning: include-what-you-use reported
diagnostics" without failing the build: CMake's own __run_co_compile
wrapper does not propagate the launched tool's exit code, so even
`-Xiwyu --error` could never fail `cmake --build` this way. Verified
this empirically by injecting a deliberately-unused #include and
confirming the build still exited 0.
Fix the findings from the last recorded run (issue #5715 item 4, log
35829411620):
- ordered_map.hpp: add <new> (placement new) and
nlohmann/detail/abi_macros.hpp; drop <memory> (std::allocator is
still visible transitively via <vector>, confirmed by full local and
containerized test suite runs).
- json_fwd.hpp: drop <memory> (same reasoning). Keep every forward
declaration IWYU wanted removed (adl_serializer, basic_json,
json_pointer, ordered_map): this file's only job is to forward-declare
them for downstream users, so "nothing in this TU uses them" is
expected, not a real finding. Mark each with `// IWYU pragma: keep`.
- json.hpp: add <cmath>, <cstdint>, <set>, <type_traits>,
<unordered_map>, and the detail/abi_macros.hpp, detail/input/json_sax.hpp,
detail/meta/detected.hpp, thirdparty/hedley/hedley.hpp includes IWYU
says it needs. Do NOT remove adl_serializer.hpp,
detail/conversions/from_json.hpp, detail/conversions/to_json.hpp,
detail/macro_unscope.hpp, or ordered_map.hpp as IWYU suggests: nothing
else in include/nlohmann includes adl_serializer.hpp or
ordered_map.hpp, so basic_json<>'s own default template arguments
(JSONSerializer = adl_serializer, and ordered_json = basic_json<ordered_map>)
would lose their complete type; detail/macro_unscope.hpp is what
undoes the JSON_* macros detail/macro_scope.hpp defines earlier in
this same file, and removing it leaks those macros into every
translation unit that includes <nlohmann/json.hpp>. Verified by
actually removing them in a scratch test: the header still "compiles"
stand-alone but ordered_json and every macro-using translation unit
break. Marked each `// IWYU pragma: keep`.
Enforce it with `iwyu_tool` (ships with IWYU, e.g. as /usr/bin/iwyu_tool
on Debian/Ubuntu) instead of relying on the launcher property: it reads
compile_commands.json (now exported project-wide under JSON_CI) and
does return a real exit code for its own analysis, independent of
CMake's wrapper. ci_single_binaries now runs it over every
src_single/*.cpp with `-Xiwyu --error`, so a *new* finding fails CI.
json.hpp itself is excluded from that hard gate: even after every fix
above, IWYU's suggestion for one remaining symbol (a container
`swap, operator!=` used somewhere via a templated comparator) is not
deterministic — repeated, otherwise-identical containerized runs
reported <set>, then <unordered_map>, then <map> as "the" header to
add/remove for the exact same source. Gating a whole CI job on a
nondeterministic suggestion would make ci_single_binaries flaky rather
than informative, so json.hpp keeps the existing informational warning
(still shown during its normal compile) without failing the build on
it. Every other one of the ~50 single-header checks is included in the
hard gate.
#5715 item 4c. 4a (scan-build) and 4b (Infer) are separate commits.
Verified: full local ctest suite (129/129) and the ci_single_binaries
target itself both green in a containerized silkeh/clang:dev run
(matching the actual CI job) after this fix; a deliberately-reintroduced
unused #include in ordered_map.hpp was confirmed to fail
`cmake --build ... --target ci_single_binaries` (exit 2) with this
change, and to pass without it, on the same container/IWYU version CI
uses. `make check-amalgamation` is clean. Compiled with Clang and GCC
at -std=c++11/14/17/20 locally with no new warnings.

* Make JSON_STRICT_NUL_HANDLING part of the ABI tag
JSON_STRICT_NUL_HANDLING (#5534) changes the bodies of inline functions:
the lexer's handling of '\0' and input_adapter() for char arrays. So
translation units compiled with and without it define the same functions
differently, an ODR violation - the case the ABI tag exists for, as with
JSON_BRACE_INIT_COPY_SEMANTICS (_bics). It now appends _snul to the inline

Its default moves to abi_macros.hpp, and it is only #undef'd without
JSON_TEST_KEEP_MACROS, as for the other ABI macros. The ABI config tests,
the namespace docs, the macro's docs and the Natvis file cover the new tag.

unget() is simulated (it rewinds only the lexer's own bookkeeping),
so that character stays consumed from the stream.

* fix: restore the character that terminates a number (#5340)
operator>> is documented to leave the stream positioned right after the
parsed value, so that concatenated JSON values can be read back to back.
That did not hold for numbers: a number is only terminated by the
character following it, and lexer::scan_number() reads that character
and calls unget() -- which is simulated and rewinds only the lexer's own
bookkeeping. input_stream_adapter consumes via sbumpc() with no matching
sungetc(), so the terminating character stayed consumed and the next
extraction started one byte too late ('1true' left the stream at 'rue').
Propagating unget() to the adapter directly does not work: next_unget
makes the following get() replay the cached character, so the terminator
would be delivered twice. Instead, restore the still-pending character
once at the end of a non-strict parse, where the input is handed back to
the caller:
- input_stream_adapter gains unget_character() (sungetc()) and advertises
it via supports_unget, detected the same way as supports_seek.
- lexer::restore_pending_unget() turns a pending simulated unget of a
real (non-EOF) character into a real one and clears next_unget so the
character is not also replayed. It is a no-op for adapters that cannot
unget, and reports failure when sungetc() fails, in which case the
input is left as it was before.
- parser calls it on the three non-strict paths, i.e. for operator>> and
sax_parse(strict = false).
Strict parse()/accept() are unaffected: they require the input to end
after the value, so the character is consumed by the end-of-input check
anyway. Parse error messages and reported positions are unchanged.

Four CI failures, all in the new test code:

`json::parse(...)`, which already returns a `json`.
- GCC (-Werror=unused-result): assign the discarded `json::parse()`
result to a dummy, the idiom used elsewhere in the test suite, and
catch `json::parse_error&` for consistency.
- clang-tidy (google-default-arguments): remove the default argument
from the `pbackfail()` override; `sungetc()` supplies the base
declaration's default.
- MSVC (bad allocation): `no_putback_streambuf::underflow()` set a
one-character get area without advancing `m_pos`, so an implementation
whose `istream::get` peeks before it bumps re-read the same character
forever. Keep no get area at all: `underflow()` peeks, `uflow()`
consumes, and `sungetc()` still always lands in `pbackfail()`, which
is what the test needs.

Read the character following a number without consuming it, instead of

putback position is required from the streambuf.

* Put the stream position fix behind JSON_PRECISE_STREAM_POSITION
Leaving the character that terminates a number in the stream is observable:
reading "1,2,3" with repeated operator>> works today only because the comma
after each number is swallowed, and std::getline after a number skips the
line break. Both break with the fix, so make it opt-in for 3.x, as suggested
by @gregmarr in the review.
- JSON_PRECISE_STREAM_POSITION (default 0) selects the peek-based
input_stream_adapter. Without it, the adapter is the consuming one from
develop and has no supports_lookahead, so lexer::release_lookahead() and
the parser's calls to it compile to nothing.
- The macro changes input_stream_adapter's layout and member functions, so
it gets the ABI tag _psp, after _bics. The ABI config tests, the natvis
generator, and nlohmann_json.natvis (regenerated) know the tag.
- The tests for the fix move to unit-precise-stream-position.cpp, which
defines the macro itself and runs in every build, and gain the two cases
above. unit-deserialization.cpp pins the default behavior instead.
- The docs describe the default behavior again and point to the new macro
page; version history says "added in 3.13.0, planned default in 4.0.0".

* Test JSON_BRACE_INIT_COPY_SEMANTICS for real, and fix one-element tuples under it
The opt-in JSON_BRACE_INIT_COPY_SEMANTICS was never exercised by CI:
- Its only test, in unit-regression3.cpp, was guarded by
`#if defined(JSON_BRACE_INIT_COPY_SEMANTICS)` after the #include. The
header #undefs the macro unconditionally in macro_unscope.hpp, so the
guard was always false and the test compiled to nothing, whatever -D
flag was passed.
- The ci_test_brace_init_copy_semantics target that passes the flag was
not named by any workflow.
Move the test into its own translation unit that defines the macro before
including the header, as unit-diagnostics.cpp does for JSON_DIAGNOSTICS.
It now runs in every CI job and for every standard. Remove the unused
target: it ran the whole suite with the macro, and that suite deliberately
relies on default brace-init semantics in about 90 places
(e.g. `json({1})` meaning `[1]`), so it could never pass.
Running the whole suite with the macro did find one library bug:
to_json for std::tuple builds `j = { std::get<Idx>(t)... }`, so with copy
semantics a one-element tuple became its element. `json(std::tuple<int>{5})`
was `5` instead of `[5]`, and `get<std::tuple<int>>()` threw type_error.302
on the result. Under the macro, a one-element tuple now builds exactly what
the default deduction builds. Without the macro nothing changes.
The new tests also pin that the library's other conversions produce the
same values with and without the macro. The macro page now says that the
macro affects every single-element list (`json j = {1}` is `1`), and that
all translation units must agree on it, since it has no ABI tag.

* Make JSON_BRACE_INIT_COPY_SEMANTICS part of the ABI tag
The macro changes the body of the initializer-list constructor and adds a
to_json_tuple_impl overload, both with the same mangled names in either
mode, so mixing translation units silently picked one definition. Encode
it in the inline namespace as `_bics`, as JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON
does with `_ldvcmp`. The macro is new in the unreleased 3.13.0, so no
existing namespace name changes.
- Move the macro's default into abi_macros.hpp so json_fwd.hpp computes
the same namespace, and keep it defined under JSON_TEST_KEEP_MACROS.
- Check the tag in the ABI config tests and in the unit test.
- List `_bics` (and the missing `_dp`) in the namespace docs and in the
natvis generator; regenerate nlohmann_json.natvis.
- Replace the "define it consistently" warning with an ABI note.
