-#
-#     test-unity-<group>_cpp<version_number>
-#
-# so that related tests, which instantiate the same templates, share one
-# translation unit. A group may mix the pools "plain" and "private"; if any of

-
-a JSON Merge Patch to convert the `source` to `target`
-
-## Exception safety
-
-Strong guarantee: `source` and `target` are never modified.
-
-## Complexity
-
-Linear in the total number of values (including nested ones) in `source` and `target`, times the cost of a key-based
-object operation (looking up a key, or adding one to the patch): logarithmic for [`json`](../json.md), and linear for
-[`ordered_json`](../ordered_json.md) (see [`ordered_map` complexity](../ordered_map.md#complexity)). For
-`ordered_json`, diffing two objects with `n` and `m` members therefore takes O((n+m)²).
-
-## Notes
-
- A merge patch uses `#!json null` to remove a member, so it cannot set a member to `#!json null`. As in RFC 7396, a
-  `#!json null` member of `target` is treated as absent: the patch removes the member from `source` instead of setting
-  it to `#!json null`. A member that is `#!json null` in both `source` and `target` is unchanged and left out of the
-  patch, so `source` keeps it.
- A merge patch cannot reorder object members, and [`merge_patch`](merge_patch.md) appends added members at the end.
-  For [`ordered_json`](../ordered_json.md), the patched value therefore has the same members as `target`, but not
-  necessarily in the same order, and may compare unequal to it. The patch lists changed and removed members in the
-  order of `source`, followed by added members in the order of `target`.
-

-
-`key` (in)

-   the last token.
-
-## Notes
-
-!!! info "Duplicate keys"
-
-    Overload 1. removes *every* member with `key`, not just the first -- unlike [`set`](set.md), which assigns the
-    first occurrence and drops the rest. This is why it returns a count rather than a single view: there may be
-    more than one member removed, or none.
-
-Like [`set`](set.md) and [`push_back`](push_back.md), `erase` never moves an element's *value*: a view still
-referring to a removed member or element keeps showing what it last held (see [Edits](index.md#edits)) -- it just no
-longer appears when `array`/`object` is read, dumped, or iterated. What does change is the container's sequence of
-*links* to its elements: removing an element of `array` (2.) shifts the links to the elements after it by one, as
-[`insert`](insert.md) does in the other direction. *Every* iterator already taken over `array`/`object` is invalidated
-by an erase, not only those at or after the removed element, since the container may now use a different sequence.

-
-An editable document (`#!cpp Editable == true`) can be changed after parsing, with [`set`](set.md),
-[`push_back`](push_back.md), [`insert`](insert.md), and [`erase`](erase.md);
-[`json_editable_document`](../json_editable_document.md) and
-[`ordered_json_editable_document`](../ordered_json_editable_document.md) are the corresponding specializations. A few
-points apply to every edit:
-
- **The source text is never written**, and the parsed index never moves: every value keeps the node it was parsed
-  into, so [views](../basic_json_view/index.md) taken before an edit stay valid, including
-  [`root()`](root.md). New values (and the element sequences of an edited array/object) go to storage owned by the
-  document, allocated on demand.
- **A view keeps referring to the same value.** After [`set`](set.md) replaces the value a view refers to, that view
-  sees the new value; a view of a value that a later edit replaces or drops keeps showing what it last held. An edit
-  of an array or object, however, **invalidates the iterators taken over it** (its members may now live in a
-  different sequence), and a string obtained with [`get_string()`](../basic_json_view/get_string.md) stays valid even
-  as further edits happen (earlier buffers of edited text are kept alive, not overwritten).
- **Values are accepted three ways:** a [`basic_json_view`](../basic_json_view/index.md) of *any* document
-  (read-only or editable; it is copied, nothing is shared with the source document), a `BasicJsonType` value, or
-  anything `BasicJsonType` can be constructed from (numbers, strings, `#!cpp bool`, `#!cpp nullptr`, containers, ...).
- [`dump()`](../basic_json_view/dump.md) writes an edited document with members in document order, new members at
-  the end, and, with [`number_format::source`](../basic_json_view/number_format.md), keeps the spelling of every
-  number that was not itself edited -- see [Editing a document](../../features/json_view.md#editing-a-document) for
-  why this matters.
- [`read()`](read.md) discards all edits, [`shrink_to_fit()`](shrink_to_fit.md) does not move the node index once
-  there are edits, and [`memory_usage()`](memory_usage.md) includes the memory edits use.
-  [`source_offset()`](../basic_json_view/source_offset.md) of a value introduced by an edit is
-  `#!cpp static_cast<std::size_t>(-1)`, the same value it reports for a decoded string.

-
-`V`
-:   the type of `value`, deduced; see above for what is accepted.

-## Parameters
-
-`array` (in)

-
-`value` (in)
-:   the value to insert
-
-## Return value
-
-a view of the new element, now holding `value`
-
-## Exception safety
-
-Basic exception safety: `value` is fully encoded -- including the checks below -- into storage owned by the document
-before anything already reachable from [`root()`](root.md) is touched, so a failure while encoding `value` (an
-invalid argument, or `#!cpp std::bad_alloc`) leaves the document completely unchanged, other than memory allocated
-for the encoding that is not reclaimed. A failure of a later allocation -- while `array` switches from its parsed
-layout to a growable block, or while that block grows, see [Notes](#notes) -- can still leave `array` already
-switched to that layout even though `value` itself was not inserted.
-
-## Exceptions
-
-Throws [`type_error.309`](../../home/exceptions.md#jsonexceptiontype_error309) if `array` is not an array -- the same
-message [`BasicJsonType::insert`](../basic_json/insert.md) throws for the same type; a null `array` throws this too
-(see above). Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if `idx` is negative,
-or if `#!cpp idx > array.size()`. Throws
-[`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) ("view does not belong to this
-document") if `array` is a [discarded](../basic_json_view/is_discarded.md) view or a view of a *different* document.
-Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if `value` is a
-[discarded](../basic_json_view/is_discarded.md) view or a [discarded](../basic_json/is_discarded.md) `BasicJsonType`
-value, and [`type_error.319`](../../home/exceptions.md#jsonexceptiontype_error319) if `value` is (or contains) a
-binary value -- `BasicJsonType` can hold one, but a `json_document` cannot. Throws
-[`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316) if `value` is (or contains) a string that is
-not valid UTF-8, with the same message [`BasicJsonType::dump()`](../basic_json/dump.md) gives for that string.
-
-## Complexity
-
-Linear in the number of elements of `array` at or after `idx` (they move one slot over), plus time linear in the
-size of `value` to encode it into the document's storage (constant for a scalar, linear in the number of nested
-values for an array or object): like [`push_back`](push_back.md), the elements of `array` move to a growable block
-of links the first time it is inserted into (or [`set`](set.md)/[`push_back`](push_back.md) on), and that block
-grows in amortized constant time; inserting before the end within that block still shifts every later element.
-
-## Notes
-
-Like [`set`](set.md) on a member or an element, `insert` never moves an existing *element's value* -- only where
-`array`'s *links* to its elements live -- so a view of an existing element of `array` stays valid across an
-`insert`, and keeps referring to the same element even though its index shifts. Any iterator already taken over
-`array` is invalidated, since it was walking the old layout. See [Edits](index.md#edits) for what stays valid across
-an edit in general.
-
-## Examples
-
-??? example
-
-    The example below inserts a step into the middle of a deployment plan, without touching the steps that come
-    after it, and shows that a view taken before the insert keeps referring to the same element even though its
-    index shifts -- something a plain `json`/`ordered_json` array, or its `std::vector`-based storage, has no
-    equivalent for.

-
-1. Reads an image [`save()`](save.md) wrote, from a pointer and a byte count. The image is **borrowed**: `image`
-   must stay alive and unchanged for as long as the returned document, and any view taken from it, is used.
-2. Reads an image from a `#!cpp std::vector`. Also **borrowed** -- equivalent to overload 1 called with
-   `#!cpp image.data()` and `#!cpp image.size()`.
-3. Reads an image, keeping the vector instead of copying it: `image` is moved into the document (no copy), which
-   then owns it for as long as it needs the text and the decoded strings. [`owns_source()`](owns_source.md) is
-   `#!cpp true` afterward.
-
-In every overload, the node index is copied into storage the document itself owns -- so that it is properly aligned,
-and, for an [editable](index.md#edits) document, can be edited -- while the text and the decoded strings stay in

-
-`check` (in)

-
-## Return value
-

-## Exception safety
-
-Overloads 1 and 2 give the strong guarantee: `image` is only read, never written, so a thrown exception leaves the

-## Complexity
-
-Linear in the number of nodes, which are always copied into the document. `#!cpp image_check::none` does not read
-the text or the decoded strings. `#!cpp image_check::bounds` reads one byte of the text for each float token (its sign,
-to check the recorded digits against the token's length), and nothing else of the text or the decoded strings.
-
-With `#!cpp image_check::full`, linear in the size of the image (the nodes, the text, and the decoded strings), plus
-sorting the ranges of the strings and of the float tokens (at most one per node): the contents of each distinct range
-are checked once, however many nodes refer to it.
-
-## Notes
-
-### `image_check` { #image_check }
-
-```cpp
-using image_check = detail::view::image_check;
-
-enum class image_check
-{
-    full,
-    bounds,
-    none
-};
-```
-
-How thoroughly `load()` validates `image` before trusting it.
-
-`full` (the default)
-:   Checks everything the parser itself guarantees: structure and bounds; that every string is valid UTF-8 (and, for a
-    string still in the source text, that it contains no quote, backslash, or control character); and that every number
-    token is well-formed and matches the value stored for it. Strings and float tokens may share a range only if the
-    ranges are identical (as nodes that share a value do), and never overlap otherwise. Reading and serializing a
-    checked image is safe and always produces valid JSON, exactly as for a parsed document. This is the right choice for
-    an image from anything you do not fully control -- a file, a cache shared with other processes, a peer on the
-    network.
-
-`bounds`
-:   Checks structure and bounds only: that every offset and count in the node index stays inside the image. So
-    `load()`, [`root()`](root.md), element access, and [`materialize()`](../basic_json_view/materialize.md) can never
-    read outside the image, even on a damaged one. It does *not* guarantee that the image describes valid JSON: a
-    string that a `full` check would have rejected can make [`dump()`](../basic_json_view/dump.md) write invalid UTF-8
-    or invalid JSON, or throw [`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316), and a number can
-    read back with a value that does not match how it is spelled. An [editable document](../json_editable_document.md)
-    does not take such a string over: [`set`](set.md), [`push_back`](push_back.md) and [`insert`](insert.md) throw
-    `type_error.316` when they copy it from a view of the loaded document, and leave the editable document unchanged.
-    `bounds` skips scanning the text and the decoded strings, so it fits a cache your own process just wrote and reads
-    straight back, where damage would mean a bug or a hardware fault rather than adversarial input.
-
-`none`
-:   Checks nothing. Reading a damaged image is undefined behavior, so use it only for an image you trust as much as
-    your own memory.
-
-**Lifetime.** Overloads 1 and 2 borrow `image`: it must stay alive and byte-for-byte unchanged for as long as the
-returned document, and any [view](../basic_json_view/index.md) taken from it, is used -- exactly like a document
-[`parse()`](parse.md) borrowed its input for. Overload 3 avoids this by keeping the vector itself; see
-[`owns_source`](owns_source.md).
-
-!!! warning "Experimental"
-
-    The image format is versioned but not yet stable, and may change in an incompatible way before it is declared
-    stable; `load()` already rejects an image written by a different format version with `parse_error.116`
-    ("unknown format"). Use images to cache a document within one build of the library, or to hand one to another
-    process running the *same* build on the *same* (little-endian) machine -- not as a long-term storage format.
-
-## Examples
-
-??? example "Caching a document, ownership, and a rejected image"
-
-    The example below saves a parsed document as an image, checks that `load()` reproduces the original
-    [`dump()`](../basic_json_view/dump.md) without parsing, and shows the difference between
-    `load(std::move(image))` (owned) and `load(image)` (borrowed). It then damages one byte of the image and shows
-    `image_check::full` rejecting it with `parse_error.116`, while `image_check::bounds` -- meant for a cache the
-    process already trusts -- still reads it without going out of bounds.

-## Complexity
-
-Amortized constant, plus time linear in the size of `value` to encode it into the document's storage (constant for
-a scalar, linear in the number of nested values for an array or object): the elements of `array` move to a growable
-block of links the first time it is appended to (or [`set`](set.md) on), and that block itself grows -- doubling its
-capacity, so the cost of growing it amortizes to constant per element -- only once it runs out of room. See
-[Notes](#notes).
-
-## Notes
-
-Like [`set`](set.md) on a member or an element, `push_back` never moves an existing element itself -- only where
-`array`'s *links* to its elements live -- so a view of an existing element of `array` stays valid across a
-`push_back`, but any iterator already taken over `array` is invalidated, since it was walking the old layout. See

-Throws [`out_of_range.416`](../../home/exceptions.md#jsonexceptionout_of_range416) if the node count, the text, or
-the decoded strings of the image would individually reach 4 GiB -- the same 32-bit offsets

-
-## Complexity
-
-Linear in the size of the document: the number of nodes, plus the length of the text and the decoded strings that end
-up in the image.
-
-## Notes
-
-**Format.** The image begins with a 64-byte header (the magic bytes `#!cpp "NJVI"`, a version number, the node count,
-and the sizes of the text and the decoded strings, all little-endian), followed by the nodes
-([16 bytes each](../../home/architecture.md#node-index-of-json-views)), the text and a `#!cpp '\0'`, and the decoded
-strings and a `#!cpp '\0'`. [`load`](load.md) checks the header, and the sizes it describes, before reading anything
-else -- see [`load`'s Exceptions](load.md#exceptions).
-
-!!! warning "Experimental"
-
-    The image format is versioned but not yet stable: it may change in an incompatible way before it is declared
-    stable. Use images to cache a document within one build of the library, or to hand one to another process running
-    the *same* build on the *same* (little-endian) machine -- not as a long-term storage format. Keep the original
-    JSON text if you need to read a saved document back with a future library version.
-
-**Little-endian only.** The image is written as raw little-endian bytes, with no byte-swapping. `save()` (and
-[`load`](load.md)) throw `type_error.320` on a big-endian target rather than silently produce bytes a big-endian
-reader could not interpret correctly.
-
-## Examples
-
-??? example "Caching a parsed document as an image"
-
-    The example below saves a parsed configuration as an image -- the way a service might cache one to answer later
-    requests without parsing the text again -- and confirms that loading it back gives exactly the same result as
-    parsing did, and that saving is deterministic.
-
-    ```cpp
-    --8<-- "examples/basic_json_document__save.cpp"
-    ```
-
-    Output:

-Only an **editable** document (`#!cpp Editable == true`, e.g. [`json_editable_document`](../json_editable_document.md))
-has `set`; calling it on a read-only `basic_json_document` fails to compile (`#!cpp static_assert`).
-
-1. Replaces the value `target` refers to with `value`.
-2. Sets the member `key` of the object `object` to `value`: assigns it if `object` already has a member with this
-   key -- the first one, should the key occur more than once, and the later duplicates are then dropped (see the
-   [Notes](#notes) below) -- or appends a new member at the end otherwise. A [null](../basic_json_view/is_null.md)
-   `object` first becomes an empty object.
-3. Assigns `value` to the element at index `idx` of the array `array`, which must already exist (`#!cpp idx <
-   array.size()`).
-4. Sets the value the JSON pointer `ptr` refers to, relative to [`root()`](root.md), to `value`. The *parent* of the
-   target must already exist: an object member is set as in 2. (added if it does not exist yet), an array element is
-   assigned as in 3., and a last reference token of `#!cpp "-"`, or equal to the size of the array, appends `value`
-   instead, exactly as [`push_back`](push_back.md) would. A [null](../basic_json_view/is_null.md) parent becomes what
-   [`basic_json::operator[]`](../basic_json/operator%5B%5D.md) with a JSON pointer makes of it: an array if the last
-   reference token is `#!cpp "-"` or consists of digits only (for an index beyond 0, the array is first filled with
-   null values up to that index), an object otherwise. An empty `ptr` sets [`root()`](root.md) itself, as in 1.
-
-In every overload, `value` is accepted three ways: a [`basic_json_view`](../basic_json_view/index.md) of *any*
-document -- read-only or editable, and it does not have to be `target`'s/`object`'s/`array`'s own document -- which
-is copied so that nothing is shared with the source document afterward; a `BasicJsonType` value; or anything
-`BasicJsonType` can be constructed from (numbers, strings, `#!cpp bool`, `#!cpp nullptr`, containers, ...).
-
-## Template parameters
-
-`V`
-:   the type of `value`, deduced; see above for what is accepted.
-
-`I`
-:   an integral type other than `#!cpp bool`, deduced (overloads taking a `#!cpp bool` or a non-integral type for
-    `idx` do not participate in overload resolution).
-
-## Parameters
-
-`target` (in)
-:   the value to replace
-
-`object` (in)
-:   the object (or null value) whose member to set
-
-`array` (in)
-:   the array whose element to assign
-
-`key` (in)
-:   the key of the member to set
-
-`idx` (in)
-:   the index of the element to assign; a negative value throws (see [Exceptions](#exceptions))
-
-`ptr` (in)
-:   a JSON pointer to the value to set, relative to `root()`
-
-`value` (in)
-:   the new value
-
-## Return value
-
-1. a view of `target`, now holding `value`
-2. a view of the member `key` of `object`, now holding `value`
-3. a view of the element `idx` of `array`, now holding `value`
-4. a view of the value `ptr` refers to, now holding `value`
-
-## Exception safety
-
-Basic exception safety: `value` is fully encoded -- including the checks below -- into storage owned by the document
-before anything already reachable from [`root()`](root.md) is touched, so a failure while encoding `value` (an
-invalid argument, or `#!cpp std::bad_alloc`) leaves the document completely unchanged, other than memory allocated
-for the encoding that is not reclaimed. A failure of a later allocation -- while an edited array or object switches
-from its parsed layout to a growable block, see [Notes](#notes) -- can still leave a partial effect, such as a
-[null](../basic_json_view/is_null.md) `object`/`array` argument already turned into an empty object/array even
-though `value` itself was not linked in. Likewise, a failure of `value` in 4. leaves a null parent that is set with an
-index beyond 0 already filled with the null values before the index.
-
-## Exceptions
-
-1. Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if `value` is a
-   [discarded](../basic_json_view/is_discarded.md) view, or a [discarded](../basic_json/is_discarded.md)
-   `BasicJsonType` value (e.g. `#!cpp BasicJsonType(value_t::discarded)`) -- an object or array `value`, of either
-   kind, is fine and is encoded as a whole subtree.
-2. Throws [`type_error.305`](../../home/exceptions.md#jsonexceptiontype_error305) if `object` is neither an object
-   nor null -- the same message [`operator[]`](../basic_json_view/operator%5B%5D.md) throws for a string argument on
-   such a value. Throws [`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316) if `key` is not
-   valid UTF-8, with the same message [`BasicJsonType::dump()`](../basic_json/dump.md) gives for that string.
-   Also throws what 1. throws for `value`.
-3. Throws `type_error.305` if `array` is not an array -- the same message `operator[]` throws for a numeric argument
-   on such a value. Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if `idx` is
-   negative, or if `#!cpp idx >= array.size()`. Also throws what 1. throws for `value`.
-4. Throws what [`at`](../basic_json_view/at.md) throws (overload 3) for resolving `ptr`'s parent, except that a
-   missing object member or an array index equal to the array's size at the very last reference token is not an
-   error there (it becomes a new member or an appended element) instead of
-   [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403)/[`out_of_range.402`](../../home/exceptions.md#jsonexceptionout_of_range402).
-   For the last reference token itself: if the parent is an object (or a primitive value, where it throws
-   `type_error.305`), throws what 2. throws; if the parent is an array, throws what 3. throws for an index that is
-   out of range, or, for a token that is not a valid array index,
-   [`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) (a leading `#!cpp '0'`),
-   [`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) (not a number),
-   [`out_of_range.410`](../../home/exceptions.md#jsonexceptionout_of_range410) (too large for `size_type`), or
-   [`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) (an empty token); the same errors are
-   thrown for a null parent and a token of digits (the parent is not changed then), and
-   [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if the index is 4294967295 or more.
-   Also throws what 1. throws for `value`.
-
-Every overload also throws [`type_error.319`](../../home/exceptions.md#jsonexceptiontype_error319) if `value` is (or
-contains) a binary value -- `BasicJsonType` can hold one, but a `json_document` cannot -- and
-[`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) ("view does not belong to this
-document") if `target`/`object`/`array` is a [discarded](../basic_json_view/is_discarded.md) view or a view of a
-*different* document (overloads 1-3 only; overload 4 always starts from this document's own [`root()`](root.md)).
-
-## Complexity
-
-1. Linear in the size of `value` (encoding it into the document's storage): constant for a scalar, linear in the
-   number of nested values for an array or object. If `target` is itself an array or object that spans more than one
-   node in its parent's original, unedited layout, and `value` is a scalar, replacing it additionally costs time
-   linear in the size of the document, the *first* time (the parent of `target` is looked up from
-   [`root()`](root.md), and then switches to links) -- see [Notes](#notes). Once the parent has links, `target` is
-   replaced in constant time: setting every element of a large array one after the other is linear overall. To avoid
-   the lookup altogether, use 3. (or 2. for an object), which know the parent.
-2. Linear in the number of members of `object`, to find an existing member with `key`, plus the complexity of 1. for
-   `value`.
-3. Constant, plus the complexity of 1. for `value`.
-4. Linear in the number of reference tokens of `ptr` and, for each token, in the number of members of the object at
-   that level or the index into the array (as [`at`](../basic_json_view/at.md)), plus the complexity of 2. or 3. for
-   the last token; for a null parent and an index, linear in the index.
-
-## Notes
-
-!!! info "Duplicate keys"
-
-    If `object` already has more than one member with `key` (2.), the *first* one is assigned `value` and every
-    later member with the same key is removed -- so that a lookup, an iteration, and
-    [`materialize()`](../basic_json_view/materialize.md) of `object` afterward all agree on a single value for
-    `key`, the same way [`operator[]`](../basic_json_view/operator%5B%5D.md) already picks the first occurrence of a
-    duplicate key for reading. See the [Notes on duplicate keys](../basic_json_view/operator%5B%5D.md#notes) of
-    `operator[]`.
-
-Setting a member (2.) or an element (3., through 4.) of an array or object whose elements have not been edited
-before switches it from its parsed layout to a growable block holding links to its elements; a later
-[`push_back`](push_back.md) or `set` on the same container reuses that block, growing it (amortized constant time)
-only once it runs out of room. This never moves an element itself -- only where the container's *links* to its
-elements live -- so a view of an element stays valid, but any iterator already taken over the container is
-invalidated, since it was walking the old layout. See [Edits](index.md#edits) for what stays valid across an edit in
-general.
-
-The same switch happens, for the same reason, when overload 1. replaces a multi-node array/object value with a
-scalar: the *parent's* element sequence is what has to switch to links, not `target` itself, because the parent
-originally stepped over `target`'s whole subtree by its node count, which no longer applies once `target` is a
-one-node scalar.
-
-## Examples
-
-??? example "Example: (1)/(2)/(3)/(4) replace a value, set a member, assign an element, set via a JSON pointer"
-
-    The example below edits a small configuration document -- replacing a value, adding an object member, assigning
-    an array element, and reaching a field through a JSON pointer -- and shows what
-    [`dump()`](../basic_json_view/dump.md) preserves that is lost once the same edits are made on a `BasicJsonType`
-    value instead: the order object members were written in, and the exact spelling of a number that was never
-    touched.
-
-    ```cpp
-    --8<-- "examples/basic_json_document__set.cpp"
-    ```
-
-    Output:
-
-    ```json
-    --8<-- "examples/basic_json_document__set.output"

Niels Lohmann	77acd4563c	Add element access, iteration, values, and JSON pointers to json_view Give basic_json_view the read-only access functions of basic_json: operator[] and at() with keys and indices, front()/back(), find(), contains(), count(), begin()/end() and cbegin()/cend(), items() with structured bindings from C++17 on, and type_name(). Exceptions have the ids and messages of the const functions of basic_json. Where basic_json has undefined behavior the view answers safely: operator[] with a missing key or an out-of-range index returns a discarded view, and front()/back() of an empty container throw invalid_iterator.214. Objects are iterated in document order, and all members are visited; duplicate-key lookups find the first member (as yyjson and simdjson do), while parse(), materialize(), and the map conversions keep the last value, as parse() does. Keys of up to 16 bytes are compared with two overlapping loads. Add value conversions: get<T>()/get_to() for arithmetic types, bool, nullptr_t, strings (std::basic_string copied, string_view_t without a copy), BasicJsonType, views, std::vector, and maps with string keys; get_string() for the string without a copy; number_token() for the number exactly as written in the source; value() with keys and JSON pointers; and operator[]/at()/ contains() with JSON pointers. Everything else, including types with from_json(), goes through materialize() of that subtree. get<T>() of arithmetic types is inlined down to the conversion, so reading an integer needs no call. detail::json_pointer_access exposes a pointer's reference tokens to code outside basic_json.

Niels Lohmann	759dd2e1b1	Add json_document and json_view: node index, parser, and document Add json_document and json_view, a read-only, zero-copy index of a JSON text, as the first public slice of the zero-copy view (#5295). A parse produces a flat array of 16-byte nodes in document order, one per value and one per object key. Strings stay in the source text; escaped strings are decoded into an arena. Integers are converted while their digits are in the cache; floats keep only their digit layout and are converted on read. Containers store the size of their subtree, so a reader can step over one in constant time. A document makes a handful of allocations, however many values it has. The parser accepts exactly what json::parse accepts, with every combination of ignore_comments and ignore_trailing_commas, with and without a trailing NUL, and under JSON_STRICT_NUL_HANDLING. It is portable C++11 and does not depend on byte order. basic_json_document adds parse, parse_copy, accept, read (reuses a document's memory), root, is_discarded, source, owns_source, node_count, memory_usage, and shrink_to_fit. basic_json_view adds type, the is_* queries, operator bool, size, empty, materialize, and source_offset. A parse error throws the same exception basic_json::parse would throw for the same input, message and position included. detail::abi_config keeps JSON_STRICT_NUL_HANDLING and JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON readable after json.hpp undefines them, in the ABI namespace so they always match the basic_json in use. A NUL byte that ends a // comment is the end of the input, as in parse() since #5696. Signed-off-by: Niels Lohmann <mail@nlohmann.me>	2026-10-07 16:42:22 +02:00
Niels Lohmann	bfa4886f0f	Write doubles with the shortest digits (Żmij), digits in registers Write doubles with the conversion of Zmij by Victor Zverovich (MIT), ported to C++11 (detail/conversions/zmij.hpp). It finds the shortest decimal that reads back as the same double, and the closest one if there are several. Grisu2, used until now, is fast but not always shortest: it sometimes writes a 17th digit where 16 suffice, or a last digit that is not the closest. The layout is unchanged (1.5, 100.0, 1e+100, -0.0); float keeps Grisu2. Digits are converted eight at a time with the BCD conversion of Xiang JunBo, as in Zmij, and written with one byte swap per eight digits and fixed-size moves instead of per-digit loops. Leading and trailing zeros are counted from those bytes. to_chars() uses a local buffer when the caller's is shorter than the 41 bytes this may write. The powers of ten come from the number-parsing table, adjusted where it holds values rounded up, and extended with Zmij's compressed tables beyond 10^308. write_shortest() converts its 16 digits in one vector register (SSE2 on x86-64, NEON on 64-bit Arm, both baseline) and inserts the decimal point inside the register, avoiding a store-forwarding stall that cost about 25% of the time to write a double. dump() writes floats and integers straight into the serializer's write buffer instead of copying them from a member buffer, and small integers eight digits at a time. read_eight_bytes() and parse_eight_digits() are marked always-inline, which GCC had been calling out of line in the number-parsing loops. Of one million random doubles, about 0.14% are now written with different digits, always to a value that still reads back as the same double.

Niels Lohmann	68d61b6aef	Speed up the lexer: own float parser, string scan, and \u table Give the library its own correctly rounded float converter for binary32 and binary64 (IEEE 754), and speed up the lexer's string and escape scanning. The converter splits a number token into sign, significand, and decimal exponent, then tries Clinger's fast path, then a templated Eisel-Lemire step, and falls back to an exact big-integer digit comparison for tokens with more than 19 significant digits whose two candidate values round differently. This replaces std::from_chars and strtod/strtof for both formats, so parsed values no longer depend on the C/C++ library or the current locale. The strtold fallback kept for other long double formats (x87, binary128) now also copies a multi-byte decimal point correctly, fixing #5660. eisel_lemire() and decimal_to_float() are always inlined so callers keep the whole conversion in their hot loop. The string-scanning kernels in string_scan.hpp find a stop byte with the trailing-zero count of the SWAR mask instead of a byte loop, and scalar_string_bulk_run() validates a run of multi-byte UTF-8 sequences one after another instead of re-searching after each one. get_codepoint() decodes a contiguous \uXXXX escape with one table lookup per byte instead of four range-checked get() calls; the streaming path and all error positions are unchanged. Adds 508 generated hard float-parsing cases with expected binary32 and binary64 bits, and kernel-comparison tests for the string scans and the escape table against byte-by-byte references.
