Niels Lohmann d4faace387 Merge develop into perf/view-compare
Develop fixed the VS 2015 build of the DOM parser itself (#5916): its
json_sax.hpp is kept, so this branch no longer changes the file.
single_include is a fresh amalgamation.

Niels Lohmann 2a56afc714 Fix VS 2015 build of the DOM parser (#5882) (#5916)
- Name std::hash only once the object type has emplace_new_key: VS 2015
  static-asserts on std::hash of a type without one (alt_string) instead of
  reporting a substitution failure (C2338).
- Replace the std::copy calls on frames by loops: VS 2015 reports raw
  pointers handed to std::copy as C4996, an error under /WX.

* docs: byte layout sections, glossary, and QA page updates

- Move "Byte layout" of each binary format to its own section before
  "Serialization" and describe the idea of the format.
- Glossary: add LLDB and other terms used throughout the documentation.
- quality_assurance: correct Clang Static Analyzer and CMake entries; add
  CodeQL, Semgrep, Flawfinder, CIFuzz, OpenSSF Scorecard, REUSE, Meson/SwiftPM,

Niels Lohmann 330fbead59 Document clang-tidy exclusions, drop unneeded ones, and clean up doc examples (#5909)
* Document clang-tidy exclusions and drop unneeded ones

Re-enable every excluded check in a run of clang-tidy 22 over all tests
and remove the seven that never fire (cert-err58-cpp,
clang-analyzer-webkit.NoUncountedMemberChecker,
cppcoreguidelines-virtual-class-destructor, google-readability-function-size,
hicpp-function-size, hicpp-no-assembler, readability-function-size).

Document the reason for every remaining exclusion at the top of the file.

Exclude in advance the checks that only exist in clang-tidy 23 and are
noise here (bugprone-signed-bitwise, *-explicit-constructor,
readability-trailing-comma, modernize-use-string-view), plus
modernize-use-integer-sign-comparison, which needs C++20 std::cmp_less
and flags deliberate casts.

* Fix clang-tidy findings in documentation examples and replace redundant aliases

Apply clang-tidy fixes to the documentation examples:
- performance-avoid-endl: std::endl -> '\n'
- readability-qualified-auto: auto -> auto* / const auto*
- performance-for-range-copy: copy -> const reference
- google-readability-casting: C-style cast -> static_cast

Replace redundant aliases (readability-redundant-qualified-alias) such as
"using json = nlohmann::json;" with "using nlohmann::json;" in the
documentation, README, examples, tests, and benchmarks. Aliases at class
scope and aliases of other types (with_base_class_t etc.) are kept.

No changes to the library or its public API. All changed examples were
compiled and run; their output matches the stored .output files (except
max_size and meta, which depend on the platform and compiler).

* Docs: fill documentation gaps found in user questions

Add pages on class-hierarchy/smart-pointer/variant/chrono recipes, working

checklist, line/column, diagnostic positions), element access, conversions,
creating values, ADL troubleshooting, memory, and build/distribution notes.
Add 14 examples with generated output. Correct the statement that parse errors
cannot be recovered from with -fno-exceptions.

The topics come from recurring questions on Stack Overflow, Reddit, Hacker
News, YouTube, and the project's GitHub discussions and issues.

Niels Lohmann 165f91ed3c Build the DOM parser with Visual Studio 2015 again
Since #5882, the three VS 2015 jobs of AppVeyor fail on develop:
- the detection of keys that can be indexed instantiated std::hash for
  every string type, which VS 2015 rejects with a static_assert for a type
  it does not hash (alt_string): std::hash is now looked at only for
  objects in a vector
- the frame stack copied its frames with std::copy to a raw pointer, which
  VS 2015 reports as unsafe (C4996, an error with /WX): a loop now

member pointer the parser stores a value of an object in is set by the

Niels Lohmann db5bd7fbcc Fix the compiler and lint failures of the json_view comparison
- all_digits(): the lambda declares its constant itself; MSVC does not
  let a lambda without captures read a constexpr local of the function
- equal(): the frame's "in document order" index is a namespace-scope
  constant (document_order); the local constexpr npos in the default
  member initializers of the local struct crashed GCC 9 and MinGW GCC
  and was not found by MSVC
- keys_differ_early() keeps the first keys in std::arrays (cpplint:
  variable-length arrays; clang-tidy: C arrays), and the basic_json
  side's first_keys() is not noexcept (key() may throw)
- the numbers of one type are compared in an if chain instead of a
  nested conditional operator
- the dump test avoids C arrays and temporary string concatenations

View comparison instructions are unchanged (Apple clang, twitter, citm,
canada: -0.1 % to +0.1 %).

Niels Lohmann 3fb7d9c710 Check the float tokens of a json_document image without a sort and a scan of every character
load(image_check::full) checked every float token of an image by sorting
the token ranges, scanning the token character by character, and comparing
the digit layout with the node's. Now:

- the ranges are sorted only if they are not sorted already (save() writes
  them in the order of the nodes, so they are);
- a token of the shape [-]digits.digits whose digit counts are the ones the
  node records (nearly all of them) is accepted by checking its digits eight
  at a time, without the general scan;
- the general scan skips runs of digits eight at a time.

Damaged tokens are still rejected as before: the check accepts exactly the
tokens that the general scan accepts.

Instructions of load(image_check::full) (develop -> now):

  macOS arm64        canada 44.6M -> 30.9M (-31 %), jeopardy 11.3M -> 10.7M,
                     citm 10.4M -> 10.0M, twitter 5.06M -> 4.94M
  Linux GCC 13       canada -50 %, jeopardy -43 %, twitter -31 %, citm -28 %
  Linux Clang 18     canada -42 %, jeopardy -48 %, twitter -35 %, citm -32 %

image_check::bounds is unchanged (within 0.4 %).

Niels Lohmann fa8134ae85 Compare json_view values without a vector per container and a basic_json per number
operator== of views (view/view, view/json, and editable documents) built two
vectors of members for every object it entered, sorted them with stable_sort
for every object, and converted each number to a basic_json value. It now:

- keeps the members of all open objects in one vector (reserved with
  geometric growth, so that nested objects do not reallocate), and orders
  them by insertion sort for up to 16 members, or not at all when the keys
  ascend already;
- compares numbers of one type directly, and builds a basic_json only for
  numbers of different types;
- compares short texts (keys, numbers, most strings) with two overlapping
  loads (bytes_equal(), in node.hpp);
- first walks both documents in lockstep, in the order of their text, which
  finds most pairs of equal values without the work of the comparison. The
  walk only enters an object if the comparison would visit its members in the
  same order (the object type keeps the order, the keys ascend, or all values
  are scalars), so a difference is never found later than before, and it
  records the containers it found different, so that the comparison does not
  walk them again;
- rejects values of different types and arrays of different sizes before any
  of this, and, for an object type that keeps the order, objects whose first
  (up to four) members have different keys, which ends a comparison that
  differs near the start without preparing the members.

Results are unchanged: numbers compare by value across types, duplicate keys
resolve as parse() resolves them, and objects compare in document order for
ordered_json and by key otherwise.

Instructions of one comparison of a document with an equal copy, macOS arm64
(develop -> now), json_document / ordered_json_document / editable:

  twitter    16.1M -> 7.0M   17.7M -> 1.5M    16.6M -> 7.3M
  citm       45.0M -> 3.4M   47.0M -> 3.2M    45.7M -> 4.3M
  canada    111.4M -> 13.7M  111.4M -> 13.7M  113.3M -> 15.0M
  jeopardy   26.2M -> 3.7M   27.3M -> 3.7M    26.6M -> 12.1M

and of a view with a basic_json value:

  twitter    11.4M -> 5.9M   11.2M -> 7.3M    11.6M -> 5.9M
  citm       33.9M -> 9.7M   32.6M -> 9.1M    34.6M -> 9.8M
  canada     92.9M -> 32.1M  92.9M -> 32.1M   93.9M -> 32.8M

and Linux instruction counts (GCC 13 / Clang 18) of the same comparisons:

  document with an equal copy   json_document     ordered_json_document   editable
    twitter                     -49 % / -52 %     -89 % / -89 %           -48 % / -50 %
    citm                        -90 % / -89 %     -91 % / -90 %           -88 % / -87 %
    jeopardy (4,000 questions)  -85 % / -85 %     -86 % / -86 %           -46 % / -49 %
  view with a basic_json value
    twitter                     -41 % / -45 %     -28 % / -35 %           -45 % / -44 %
    citm                        -63 % / -65 %     -63 % / -66 %           -65 % / -64 %
    jeopardy                    -39 % / -43 %     -14 % / -24 %           -44 % / -43 %

A sweep that places one difference at about 2,100 positions of eight
documents (a token at an even spacing, the first and last tokens, the first,
middle and last member of the root removed, one appended, the document
wrapped) in five kinds of comparison (view/view of read-only and of editable
documents, view/json, json_document, editable/view) finds the same results as
before and no placement slower on the Mac (Clang); on Linux no placement is
slower than 3 % (Clang and GCC).

The second template parameter of [`basic_json_document`](basic_json_document/index.md) and
[`basic_json_view`](basic_json_view/index.md): whether a document can be changed after parsing, and whether a view is
of such a document.
`read_only`
: the default: the document is parsed once and then only read. It carries none of the bookkeeping edits need, and
calling [`set`](basic_json_document/set.md), [`push_back`](basic_json_document/push_back.md),
[`insert`](basic_json_document/insert.md), or [`erase`](basic_json_document/erase.md) on it fails to compile.
`editable`
: the document also offers [`set`](basic_json_document/set.md), [`push_back`](basic_json_document/push_back.md),
[`insert`](basic_json_document/insert.md), and [`erase`](basic_json_document/erase.md); its views see every edit,
see [Edits](basic_json_document/index.md#edits).
The shortcuts name both modes: [`json_document`](json_document.md) and [`json_view`](json_view.md) are read-only,
[`json_editable_document`](json_editable_document.md) and [`json_editable_view`](json_editable_view.md) are editable
(and likewise for `ordered_json`).
## Notes
The mode is part of the view's type, and there is no conversion between the two modes: a read-only view reads a
container in place, while a view of an editable document follows the links that edits leave behind. A function that
accepts views therefore names the modes it accepts in its signature:
```cpp
// views of editable documents only
template<typename BasicJsonType>
void f(basic_json_view<BasicJsonType, view_mode::editable> v);
// views of read-only documents only
template<typename BasicJsonType>
void f(basic_json_view<BasicJsonType, view_mode::read_only> v);
// either
template<typename BasicJsonType, view_mode Mode>
void f(basic_json_view<BasicJsonType, Mode> v);
```
A function that takes a [`json_view`](json_view.md) accepts neither an [`ordered_json_view`](ordered_json_view.md)
nor a [`json_editable_view`](json_editable_view.md). Views of the two modes still compare with
[`operator==`](basic_json_view/operator_eq.md).
## Examples
??? example
The example below shows a function template that accepts the views of both modes, and one that accepts only
views of editable documents.
```cpp
--8<-- "examples/view_mode.cpp"
```
Output:
```
--8<-- "examples/view_mode.output"
```
