 We recommend that you run your tests using different optimization levels. In particular, we recommend your run tests with the simdjson library and you code compiled in debug mode. The simdjson then sets the SIMDJSON_DEVELOPMENT_CHECKS macro to 1, and this triggers additional checks on your code and on the internals of the library. If possible, we recommend that you run tests with sanitizers (e.g., see [No more leaks with sanitize flags in gcc and clang](https://lemire.me/blog/2016/04/20/no-more-leaks-with-sanitize-flags-in-gcc-and-clang/)).  You can compile the library with sanitizers for debugging purposes (e.g., set SIMDJSON_SANITIZE to ON using CMake), but you should also turn on sanitizers on your own code. You may also use tools like valgrind or the commercial equivalent.

-# AI Usage Policy
-
-Contributors can use whatever tools they would like to
-craft their contributions, but there must be a **human in the loop**.
-**Contributors must read and review all LLM-generated code or text before they
-ask other project members to review it.** The contributor is always the author
-and is fully accountable for their contributions. Contributors should be
-sufficiently confident that the contribution is high enough quality that asking
-for a review is a good use of scarce maintainer time, and they should be **able
-to answer questions about their work** during review.
-
-We expect that new contributors will be less confident in their contributions,
-and our guidance to them is to **start with small contributions** that they can
-fully understand to build confidence. We aspire to be a welcoming community
-that helps new contributors grow their expertise, but learning involves taking
-small steps, getting feedback, and iterating. Passing maintainer feedback to an
-LLM doesn't help anyone grow, and does not sustain our community.
-
-This policy includes, but is not limited to, the following kinds of
-contributions:
-
-- Code, usually in the form of a pull request
-- Issues or security vulnerabilities
-- Comments and feedback on pull requests
-
-## Extractive Contributions
-
-The reason for our "human-in-the-loop" contribution policy is that processing
-patches, PRs, RFCs, and comments is not free -- it takes a lot of
-maintainer time and energy to review those contributions! Sending the
-unreviewed output of an LLM to open source project maintainers *extracts* work
-from them in the form of design and code review, so we call this kind of
-contribution an "extractive contribution".
-
-## Transparency
-
-For contributions involving significant AI assistance, we encourage you to disclose
-its use and explain your process. If a submission appears to rely heavily on AI
-without disclosure, we may doubt that the **human-in-the-loop** requirement has
-been met. Please show awareness of your use of AI.
-
-## Copyright
-
-Artificial intelligence systems raise many questions around copyright that have
-yet to be answered. Our policy on AI tools is similar to our copyright policy:
-Contributors are responsible for ensuring that they have the right to
-contribute code under the terms of our license, typically meaning that either
-they, their employer, or their collaborators hold the copyright. Using AI tools
-to regenerate copyrighted material does not remove the copyright, and
-contributors are responsible for ensuring that such material does not appear in
-their contributions. Contributions found to violate this policy will be removed
-just like any other offending contribution.

 Directory Structure and Source
 ------------------------------
 
-Before diving into the directory structure, here are key concepts used in the codebase:
-
-- **Amalgamated File**: A file that is conditionally included in the amalgamation process. These are wrapped in `#ifndef SIMDJSON_CONDITIONAL_INCLUDE` blocks and are included based on the target implementation (e.g., ARM64, x86). They include implementation-specific files (e.g., `arm64.h`) and generic files (e.g., under `generic/`). Amalgamated files have associated dependency files (`dependencies.h`) to track includes.
-
-- **Amalgamator File**: A file that orchestrates the inclusion of amalgamated files. Examples: `arm64.h`, `arm64/implementation.h`, `generic/amalgamated.h`. These are not themselves amalgamated but control conditional inclusions.
-
-- **Free Dependency File**: A top-level header that is always included unconditionally. These do not have dependency files and represent the public API (e.g., main headers).
-
-- **Implementation-Specific File**: A file tied to a specific CPU architecture or instruction set (e.g., `arm64/`, `haswell/`). These must be amalgamated.
-
-- **Generic File**: A shared file (under `generic/` or `simdjson/generic/`) that contains common code included once per implementation.
-
-- **Builtin File**: Special files under `simdjson/builtin/` that handle the builtin implementation, a fallback/default implementation used when no optimized implementation is available.
-
-- **Conditional Include Block**: A section wrapped in `#ifndef SIMDJSON_CONDITIONAL_INCLUDE` for editor-only or implementation-specific content.
-
-The script `singleheader/amalgation_helper.py` will generate an HTML report which you can use to visualize the status of each file.

-# Accessor Performance Benchmarks (C++26)
-
-These benchmarks compare the performance of runtime vs compile-time JSON accessors.
-For the comparison to be meaningful, you must build simdjson with support for
-C++26 reflexion. See the `p2996` repository in the main project directory.
-
-## Files
-
-- `accessor_benchmark.h` - Common benchmark framework and test data
-- `runtime_accessors.h` - Runtime `at_path()` benchmarks
-- `compile_time_accessors.h` - Compile-time `at_path_compiled()` benchmarks (requires C++26 reflection)
-
-## Benchmarks
-
-Each benchmark measures parsing + single field access:
-
-1. **accessor_simple** - Simple field: `.name`
-2. **accessor_nested** - Nested field: `.address.city`
-3. **accessor_deep** - Deep nested field: `.address.coordinates.lat`
-
-## Building (Linux/macOS)
-
-```bash
-cmake -B build -D SIMDJSON_STATIC_REFLECTION=ON -DSIMDJSON_DEVELOPER_MODE=ON
-cmake --build build --target=bench_ondemand
-```
-
-The `SIMDJSON_STATIC_REFLECTION` will be made unnecessary once mainstream compilers
-begin supporting C++26 sufficiently well.
-
-## Running (Linux/macOS)
-
-
-```bash
-# Run all accessor benchmarks
-./build/bench_ondemand --benchmark_filter="accessor"
-```
-
-## Results
-
-We find that compile-time accessors show performance improvements that scale with path depth:
-- Simple fields: ~1.2x faster
-- Nested fields: ~1.5x faster
-- Deep nested fields: ~1.8x faster
-
-The speedup comes from eliminating runtime path parsing and conversion overhead.

-Overview: string_builder
----------------------------
-
-The string_builder class is a low-level utility for constructing JSON strings representing documents. It is optimized for performance, potentially leveraging kernel-specific features like SIMD instructions for tasks such as string escaping. This class supports atomic types (e.g., booleans, numbers, strings) but does not handle composed types directly (like arrays or objects).
-Note that JSON strings are always encoded as UTF-8.
-
-An `string_builder` is created with an initial buffer capacity (e.g., 1kB). The memory
-is reallocated when needed.
-The efficiency of `string_builder` stems from its internal use of a resizable array or buffer. When you append data, it adds the characters to this buffer, resizing it only when necessary, typically in a way that minimizes reallocations. This approach contrasts with regular string concatenation, where each operation creates a new string, copying all previous content, leading to quadratic time complexity for repeated concatenations.
-
-
-It has the following methods to add content to the string:
-
-
-- `append(number_type v)`: Appends a number (including booleans) to the JSON buffer. Booleans are converted to the strings "false" or "true". Numbers are formatted according to the JSON standard, with floating-point numbers using the shortest representation that accurately reflects the value.
-- `append(char c)`: Appends a single character to the JSON buffer.
-- `append_null()`: Appends the string "null" to the JSON buffer.
-- `clear()`: Clears the contents of the JSON buffer, resetting the position to 0 while retaining the allocated capacity.
-- `escape_and_append(std::string_view input)`: Appends a string view to the JSON buffer after escaping special characters (e.g., quotes, backslashes) as required by JSON.
-- `escape_and_append_with_quotes(std::string_view input)` Appends a string view surrounded by double quotes (e.g., "input") to the JSON buffer after escaping special characters. For constant strings, you may also do `escape_and_append_with_quotes<"mystring">()`.
-- `escape_and_append_with_quotes(char input)`: Appends a single character surrounded by double quotes (e.g., "c") to the JSON buffer after escaping it if necessary.
-- `append_raw(const char *c)`: Appends a null-terminated C string directly to the JSON buffer without escaping.
-- `append_raw(std::string_view input)`: Appends a string view directly to the JSON buffer without escaping.
-- `append_raw(const char *str, size_t len)`: Appends a specified number of characters from a C string directly to the JSON
-- `append_key_value(key,value)`: Appends a key and a value (`"json":somevalue`)
-- `append_key_value<"mykey">(value)`: Appends a key and a value (`"json":somevalue`), useful when the key is a compile-time constant (C++20).
-
-After writing the content, if you have reasons to believe that the content might violate UTF-8 conventions, you can check it as follows:
-
-- `validate_unicode()`: Checks if the content in the JSON buffer is valid UTF-8. Returns: true if the content is valid UTF-8, false otherwise.
-
-You might need to do unicode validation if you have strings in your data structures containing
-malformed UTF-8. Note that we do not automatically call `validate_unicode()`.
-
-Once you are satisfied, you can recover the string as follows:
-
-- `operator std::string()`: Converts the JSON buffer to an std::string. (Might throw if an error occurred.)
-- `operator std::string_view()`: Converts the JSON buffer to an std::string_view.  (Might throw if an error occurred.)
-- `view()`: Returns a view of the written JSON buffer as a `simdjson_result<std::string_view>` (C++20).
-
-The later method (`view()`) is recommended.  For performance reasons, we expect you to explicitly call `validate_unicode()` as needed (e.g., prior to calling `view()`).
-
-Example: string_builder
----------------------------
-
-```cpp
-struct Car {
-    std::string make;
-    std::string model;
-    int64_t year;
-    std::vector<double> tire_pressure;
-};
-
-void serialize_car(const Car& car, simdjson::builder::string_builder& builder) {
-    // start of JSON
-    builder.start_object();
-
-    // "make"
-    builder.append_key_value("make", car.make);
-    builder.append_comma();
-
-    // "model"
-    builder.append_key_value("model", car.model);
-    builder.append_comma();
-
-    // "year"
-    builder.append_key_value("year", car.year);
-    builder.append_comma();
-
-    // "tire_pressure"
-    builder.escape_and_append_with_quotes("tire_pressure");
-    builder.append_colon();
-    builder.start_array();
-    // vector tire_pressure
-    for (size_t i = 0; i < car.tire_pressure.size(); ++i) {
-        builder.append(car.tire_pressure[i]);
-        if (i < car.tire_pressure.size() - 1) {
-            builder.append_comma();
-        }
-    }
-    builder.end_array();
-    builder.end_object();
-}
-
-bool car_test() {
-    simdjson::builder::string_builder sb;
-    Car c = {"Toyota", "Corolla", 2017, {30.0,30.2,30.513,30.79}};
-    serialize_car(c, sb);
-    std::string_view p{sb};
-    // p holds the JSON:
-    // "{\"make\":\"Toyota\",\"model\":\"Corolla\",\"year\":2017,\"tire_pressure\":[30.0,30.2,30.513,30.79]}"
-    return true;
-}
-```
-
-
-
-
-The `string_builder` constructor takes an optional parameter which specifies the initial
-memory allocation in byte. If you know approximately the size of your JSON output, you can
-pass this value as a parameter (e.g., `simdjson::builder::string_builder sb{1233213}`).
-
-The `string_builder` might throw an exception in case of error when you cast it result to `std::string_view`. If you wish to avoid exceptions, you can use the following programming pattern:
-
-```cpp
-    std::string_view p;
-    if(sb.view().get(p)) {
-        return false; // there was an error
-    }
-```
-
-In all cases, the `std::string_view` instance depends the corresponding `string_builder` instance.
-
-### C++20
-
-
-
-If you have C++20, you can simplify the code, as the `std::vector<double>` is automatically supported. Further, we can pass the keys (which are compile-time
-constant) as template parameter (for improved performance).
-
-```cpp
-    Car c = {"Toyota", "Corolla", 2017, {30.0,30.2,30.513,30.79}};
-    simdjson::builder::string_builder sb;
-    sb.start_object();
-    sb.append_key_value<"make">(c.make);
-    sb.append_comma();
-    sb.append_key_value<"model">(c.model);
-    sb.append_comma();
-    sb.append_key_value<"year">(c.year);
-    sb.append_comma();
-    sb.append_key_value<"tire_pressure">(c.tire_pressure);
-    sb.end_object();
-    std::string_view p = sb.view();
-```
-
-With C++20, you can similarly handle standard containers transparently.
-For example, you can serialize `std::map<std::string,T>` types.
-
-```cpp
-    std::map<std::string,double> c = {{"key1", 1}, {"key2", 1}};
-    simdjson::builder::string_builder sb;
-    sb.append(c);
-    std::string_view p = sb.view();
-```
-
-You can also serialize `std::vector<T>` types.
-
-```cpp
-    std::vector<std::vector<double>> c = {{1.0, 2.0}, {3.0, 4.0}};
-    simdjson::builder::string_builder sb;
-    sb.append(c);
-    std::string_view p = sb.view();
-```
-
-You can also skip the creation for the `string_builder` instance in such simple cases.
-
-```cpp
-std::vector<std::vector<double>> c = {{1.0, 2.0}, {3.0, 4.0}};
-std::string json = simdjson::to_json(c);
-```
-
-We also have an overload for when you want to reuse the same `std::string` instance:
-
-
-```cpp
-std::vector<std::vector<double>> c = {{1.0, 2.0}, {3.0, 4.0}};
-std::string json;
-auto error = simdjson::to_json(c, json);
-if(error) { /* there was an error */ }
-```
-
-
-We do recommend that you create and reuse the `string_builder` instance for performance
-reasons.
-
-You can also add custom serialization functions using a `tag_invoke` function.
-For example, the following
-function will allow you to serialize instances of the type `Car`.
-
-```cpp
-#include <simdjson>
-
-struct Car {
-  std::string make;
-  std::string model;
-  int64_t year;
-  std::vector<float> tire_pressure;
-};
-
-namespace simdjson {
-
-template <typename builder_type>
-void tag_invoke(serialize_tag, builder_type &builder, const Car& car) {
-  builder.start_object();
-  builder.append_key_value("make", car.make);
-  builder.append_comma();
-  builder.append_key_value("model", car.model);
-  builder.append_comma();
-  builder.append_key_value("year", car.year);
-  builder.append_comma();
-  builder.append_key_value("tire_pressure", car.tire_pressure);
-  builder.end_object();
-}
-
-} // namespace simdjson
-```
-
-C++26 static reflection
-------------------------
-
-Static reflection (or compile-time reflection) in C++26 introduces a powerful compile-time mechanism that allows a program to inspect and manipulate its own structure, such as types, variables, functions, and other program elements, during compilation. Unlike runtime reflection in languages like Java or Python, C++26’s static reflection operates entirely at compile time, aligning with C++’s emphasis on zero-overhead abstractions and high performance. It means
-that you can delegate much of the work to the library.
-If you have a compiler with support C++26 static reflection, you can compile
-your code with the `SIMDJSON_STATIC_REFLECTION` macro set:
-
-```cpp
-#define SIMDJSON_STATIC_REFLECTION 1
-//...
-#include "simdjson.h"
-```
-
-And then you can append your data structures to a `string_builder` instance
-automatically. In most cases, it should work automatically:
-
-```cpp
-    struct Car {
-        std::string make;
-        std::string model;
-        int64_t year;
-        std::vector<double> tire_pressure;
-    };
-
-    bool car_test() {
-        simdjson::builder::string_builder sb;
-        Car c = {"Toyota", "Corolla", 2017, {30.0,30.2,30.513,30.79}};
-        sb << c;
-        std::string_view p{sb};
-        // p holds the JSON:
-        // "{\"make\":\"Toyota\",\"model\":\"Corolla\",\"year\":2017,\"tire_pressure\":[30.0,30.2,30.513,30.79]}"
-        return true;
-    }
-```
-
-
-### Without `string_buffer` instance
-
-In some instances, you might want to create a string directly from your own data type.
-You can create a string directly, without an explicit `string_builder` instance
-with the `simdjson::to_json` template function.
-(Under the hood a `string_builder` instance may still be created.)
-
-```cpp
-    struct Car {
-        std::string make;
-        std::string model;
-        int64_t year;
-        std::vector<double> tire_pressure;
-    };
-
-    void f() {
-        Car c = {"Toyota", "Corolla", 2017, {30.0,30.2,30.513,30.79}};
-        std::string json = simdjson::to_json(c);
-    }
-```
-
-If you know the output size, in bytes, of your JSON string, you may
-pass it as a second parameter (e.g., `simdjson::to_json(c, 31123)`).
-
-Sometimes you may want to reuse the same `std::string` instance. We
-have an overload for this purpose:
-
-```cpp
-Car c = {"Toyota", "Corolla", 2017, {30.0,30.2,30.513,30.79}};
-std::string s;
-auto error = simdjson::to_json(c, s);
-if(error) { /* there was an error */ }
-```
-
-You can then also add a third parameter for the expected output size in bytes.
-
-### Extracting just some fields
-In some instances, your class might have many fields that you do not want to serialize.
-You can achieve this result with the `simdjson::extract_from` template. In the following
-example, we serialize only the `year` and `price` fields on the `Car` instance.
-```cpp
-struct Car {
-    std::string make;
-    std::string model;
-    int year;
-    double price;
-    bool electric;
-};
-Car car{"Ford", "F-150", 2024, 55000.0, false};
-// Extract year and price
-std::string json_result = simdjson::extract_from<"year", "price">(car);
-// Alternatively:
-// std::string json_result;
-// auto error =  extract_from<"year", "price">(car).get(json_result);
-// if(error) { /* error handling */ }
-```
-
-### Without `string_buffer` instance but with explicit error handling
-
-If prefer a version without exceptions and explicit error handling, you can use the following
-pattern:
-
-```cpp
-  std::string json;
-  if(simdjson::to_json(c).get(json)) {
-    // there was an error
-  } else {
-    // json contain the serialized JSON
-  }
-```
-
-### Customization
-
-If you want to serialize a value in a custom way, you can do it with a
-`tag_invoke` specialization like the following example which will map
-the year attribute to a string.
-
-
-```cpp
-#include <simdjson>
-
-struct Car {
-  std::string make;
-  std::string model;
-  int64_t year;
-  std::vector<float> tire_pressure;
-};
-
-namespace simdjson {
-
-template <typename builder_type>
-void tag_invoke(serialize_tag, builder_type &builder, const Car& car) {
-  builder.start_object();
-  builder.append_key_value("make", car.make);
-  builder.append_comma();
-  builder.append_key_value("model", car.model);
-  builder.append_comma();
-  builder.append_key_value("year", std::to_string(car.year));
-  builder.append_comma();
-  builder.append_key_value("tire_pressure", car.tire_pressure);
-  builder.end_object();
-}
-
-} // namespace simdjson
-```
-
-### Pretty formatted (fractured JSON)
-
-In some instances, you may want your JSON to be more readable. For this pupose, we also
-support the Fractured JSON standard.
-
-```Cpp
-  TableTestData data{
-    {{1, "Alice", true}, {2, "Bob", false}, {3, "Carol", true}, {4, "Dave", false}}
-  };
-
-  fractured_json_options opts;
-  opts.enable_table_format = true;
-  opts.min_table_rows = 3;
-
-  std::string formatted = simdjson::to_fractured_json_string(data, opts);
-```
-
-The result might be as follows.
-
-```json
-{
-    "records": [
-        { "active": true , "id": 1, "name": "Alice" },
-        { "active": false, "id": 2, "name": "Bob" },
-        { "active": true , "id": 3, "name": "Carol" },
-        { "active": false, "id": 4, "name": "Dave" }
-    ]
-}
-```
-
-The `fractured_json_options` struct allows you to customize the formatting behavior. It includes the following options:
-
-- `max_total_line_length` (default: 120): Maximum total characters per line. Content exceeding this will be expanded to multiple lines.
-- `max_inline_length` (default: 80): Maximum length for inlined elements. Simple arrays/objects shorter than this may be rendered inline.
-- `max_inline_complexity` (default: 2): Maximum nesting depth for inline rendering. Elements with complexity exceeding this will be expanded. Complexity 0 = scalar, 1 = flat array/object, 2 = one level of nesting.
-- `max_compact_array_complexity` (default: 1): Maximum complexity for compact array formatting. Arrays with elements of this complexity or less may have multiple items per line.
-- `indent_spaces` (default: 4): Number of spaces per indentation level.
-- `enable_table_format` (default: true): Enable tabular formatting for arrays of similar objects. When enabled, arrays of objects with identical keys are formatted as aligned tables.
-- `min_table_rows` (default: 3): Minimum number of rows to trigger table mode.
-- `table_similarity_threshold` (default: 0.8): Similarity threshold for table detection. Objects must share at least this fraction of keys to be formatted as a table.
-- `enable_compact_multiline` (default: true): Enable compact multiline arrays. When enabled, arrays of simple elements may have multiple items per line.
-- `max_items_per_line` (default: 10): Maximum array items per line in compact mode.
-- `simple_bracket_padding` (default: true): Add space inside brackets for simple containers. When true: `{ "key": "value" }`, when false: `{"key": "value"}`.
-- `colon_padding` (default: true): Add space after colons. When true: `"key": "value"`, when false: `"key":"value"`.
-- `comma_padding` (default: true): Add space after commas in inline content. When true: `[1, 2, 3]`, when false: `[1,2,3]`.

-## Introduction
-In some instances, you may want to configure your software at compile-time with a JSON document.
-Maybe you have a single code base but many different possible configurations, all resulting in
-different software. For example, you might be programming robots, using the same software, but
-different robot configurations.
-
-To achieve the desired result, you have a few options. You may start the software and parser a
-JSON file at runtime. Or you might convert your JSON data into C++ code that you can compile with
-your software.
-
-With C++26, there is another way: parse the JSON file along with your C++ code. In this manner,
-the JSON data becomes native C++ data.
-
-The simdjson library supports parsing JSON documents at compile time if you have C++26 support. To
-activate C++26 reflection support, you can compile
-your code with the `SIMDJSON_STATIC_REFLECTION` macro set:
-
-```cpp

-
-The `simdjson::compile_time::parse_json` function parses a JSON document at **compile time** and returns a `constexpr` structure reflecting its content. We support the full range of JSON values, which are mapped to C++ types as in
-the following table.
-
-
-| JSON type      | C++ type                         |
-|----------------|----------------------------------|
-| object         | anonymous struct                 |
-| array          | `std::array<T, N>` (homogeneous) |
-| string         | `const char*` (UTF-8)            |
-| number         | `int64_t`, `uint64_t`, `double`  |
-| `true`/`false` | `bool`                           |
-| `null`         | `std::nullptr_t`                 |
-
-## Example
-
-Suppose you want to parse the following JSON document:
-
-```cpp
-{
-    "port": 8080,
-    "host": "localhost",
-    "debug": true
-}
-```
-
-**Reminder**: In C++, `R"( )"` allows us to write multi-line strings with unescaped quotes.
-
-
-You can do so, at compile-time, as follows:
-
-
-```cpp
-constexpr auto cfg = R"(
-
-{
-    "port": 8080,
-    "host": "localhost",
-    "debug": true
-}
-
-)"_json;
-
-// cfg.port == 8080
-// std::string_view(cfg.host) == "localhost"
-// cfg.debug == true
-```
-
-You can nest objects and arrays:
-
-```cpp
-constexpr auto data = R"(
-
-{
-    "servers": [
-        {"host": "s1", "port": 3000},
-        {"host": "s2", "port": 3001}
-    ]
-}
-
-)"_json;
-
-
-// data.servers.size() == 2
-// std::string_view(data.servers[0].host) == "s1"
-```
-
-Top-level arrays are allowed:
-
-```cpp
-constexpr auto arr = R"(
-
-[1, 2, 3]
-
-)"_json;
-static_assert(arr.size() == 3);
-static_assert(arr[1] == 2);
-```
-
-
-## Concepts
-
-Given that the parsed data is made of structures that depend on the JSON input, you might
-want to check that it conforms to your expectation. You can do so with concepts.
-
-Let us consider this example:
-
-```cpp
-    constexpr auto config = R"(
-
-    [
-      { "name": "Alice", "age": 30 },
-      { "name": "Bob", "age": 25 },
-      { "name": "Charlie", "age": 35 }
-    ]
-
-    )"_json;
-```
-
-You might want to ensure that the result is an array of persons. You can define your
-expectation with concepts like so:
-
-```cpp
-template <typename T>
-concept person = requires(T p) {
-    std::string_view(p.name);  // has name field convertible to string_view
-    p.age;                     // has age field
-    requires std::is_integral_v<decltype(p.age)>;  // age is integral
-};
-
-/**
- * Concept to validate that a type is an array of person objects
- */
-template <typename T>
-concept array_of_person = requires(T arr) {
-    arr.size();                    // has size method
-    arr[0];                        // can access elements with []
-    requires person<decltype(arr[0])>;  // elements satisfy person concept
-};
-```
-
-And then a simple static assert with `decltype` is sufficient to check that the expectation is met:
-
-```cpp
-  constexpr auto config = R"(
-
-  [
-    { "name": "Alice", "age": 30 },
-    { "name": "Bob", "age": 25 },
-    { "name": "Charlie", "age": 35 }
-  ]
-
-  )"_json;
-
-
-  // Validate that the array satisfies the array_of_person concept
-  static_assert(array_of_person<decltype(config)>);
-```
-
-
-
-## Loading from disk
-
-In practice, you may have a JSON file, say `json_data` that you want to parse
-at compile time. You may do so as follows.
-
-```c++
-constexpr const char json_data[] = {
-    #embed "test.json"
-    , 0
-};
-
-constexpr auto json = simdjson::compile_time::parse_json<json_data>();
-```
-
-
-## Limitations (compile-time errors)
-
-We have a few limitations which trigger compile-time errors if violated.
-
-
-- Only JSON objects and arrays are supported at the top level (no primitives).
-  We will lift this limitation in the future.
-- Strings are represented using the `const char*` in UTF-8, but they must not
-  contain embedded nulls. We would prefer to represent them as std::string or
-  std::string_view, and hope to do so in the future.
-- Heterogeneous arrays are not supported yet. E.g., you need to have arrays of
-  all integers, or all strings, all floats, all compatible objects, etc.
-  For example, the following is accepted:
-  ```json
-   [
-    { "name": "Alice", "age": 30 },
-    { "name": "Bob", "age": 25 },
-    { "name": "Charlie", "age": 35 }
-  ]
-  ```
-  but the following is not:
-  ```json
-  [
-    { "name": "Alice", "age": 30 },
-    "Just a string",
-    42,
-    { "name": "Charlie", "age": 35 }
-  ]
-  ```
-  We may support heterogeneous arrays in the future with std::variant types.
-- We parse the first JSON document encountered in the string. Trailing
-  characters are ignored. Thus if your JSON begins with {"a":1}, everything
-  after the closing brace is ignored. This limitation will be lifted in the future,
-  reporting an error.
-
-These limitations are safe in the sense that they result in compile-time errors.
-Thus you will not get truncated strings or imprecise floats silently.
-
-
-Although we are committed to maintaining the functionality in the long run, the
-`compile_time::parse_json` function is subject to change.

-# Compile-Time JSONPath and JSON Pointer Accessors
-
-**Note:** This feature requires C++26 Static Reflection support (P2996) and is currently only available with experimental compilers. You must enable it with `-DSIMDJSON_STATIC_REFLECTION=ON` when building.
-
-## Overview
-
-simdjson provides compile-time JSONPath and JSON Pointer accessors that validate paths against struct definitions at compile time and generate optimized accessor code with zero runtime overhead. This combines the safety of compile-time type checking with the performance of pre-parsed, pre-validated access paths.
-
-## Requirements
-
-- C++26 compiler with Static Reflection support (P2996)
-- Experimental compiler flags:
-  - Clang with P2996 support: `-std=c++26 -freflection -fexpansion-statements`
-- Build configuration: `-DSIMDJSON_STATIC_REFLECTION=ON`
-
-## How It Works
-
-**Compile Time:**
-1. Path string is parsed and converted to access steps
-2. Path is validated against struct definition using reflection
-3. Field types are checked and verified
-4. Optimized accessor code is generated
-
-**Runtime:**
-- Direct navigation with no parsing
-- No validation overhead
-- No string comparisons for path components
-- Type-safe extraction
-
-## Two Usage Modes
-
-### Mode 1: With Type Validation (Recommended)
-
-When you provide a struct type, the compiler validates the entire path at compile time:
-
-```cpp
-struct User {
-  std::string name;
-  int age;
-  std::vector<std::string> emails;
-};
-
-//  R"( ... )" is a C++ raw string literal.
-const padded_string json = R"({
-  "name": "Alice",
-  "age": 30,
-  "emails": ["alice@example.com", "alice@work.com"]
-})"_padded;
-
-ondemand::parser parser;
-auto doc = parser.iterate(json);
-
-// Compile-time validation: checks that User has "name" field of type std::string
-std::string name;
-auto result = ondemand::json_path::at_path_compiled<User, ".name">(doc);
-result.get(name); // name = "Alice"
-
-// Compile-time validation: checks that "emails" is array-like with string elements
-std::string email;
-result = ondemand::json_path::at_path_compiled<User, ".emails[0]">(doc);
-result.get(email); // email = "alice@example.com"
-```
-
-**Benefits:**
-- **Compile-time errors** if path doesn't exist in struct
-- **Type safety** - verifies field types match expected types
-- **Refactoring protection** - renaming struct fields causes compile errors
-
-**What gets validated:**
-- Field existence
-- Field types
-- Array/container access validity
-- Nested struct navigation
-
-### Mode 2: Without Validation
-
-When you omit the struct type, the path is parsed at compile time but not validated:
-
-```cpp
-const padded_string json = R"({
-  "name": "Alice",
-  "age": 30,
-  "address": {"city": "Boston"}
-})"_padded;
-
-ondemand::parser parser;
-auto doc = parser.iterate(json);
-
-// No compile-time validation - path is only parsed
-std::string name;
-auto result = ondemand::json_path::at_path_compiled<".name">(doc);
-result.get(name); // name = "Alice"
-
-std::string_view city;
-result = ondemand::json_path::at_path_compiled<".address.city">(doc);
-result.get(city); // city = "Boston"
-```
-
-**Benefits:**
-- Works with dynamic/unknown JSON structures
-- Still benefits from compile-time path parsing
-- No runtime string parsing overhead
-
-**Use when:**
-- JSON structure is not known at compile time
-- Working with varied JSON schemas
-- Prototyping or exploratory parsing
-
-## JSONPath Syntax
-
-JSONPath uses dot notation and bracket notation for field access:
-
-### Supported Syntax
-
-| Syntax | Description | Example |
-|--------|-------------|---------|
-| `.field` | Dot notation for field access | `.name`, `.address.city` |
-| `["field"]` | Bracket notation with quotes | `["name"]`, `["address"]["city"]` |
-| `[index]` | Array index access | `[0]`, `[1]` |
-| Mixed | Combination of notations | `.emails[0]`, `["users"][0].name` |
-| `$` prefix | Optional root indicator | `$.name`, `$["name"]` |
-
-### Examples
-
-```cpp
-struct Address {
-  std::string city;
-  int zip;
-};
-
-struct Person {
-  std::string name;
-  int age;
-  Address address;
-  std::vector<std::string> emails;
-};
-
-// Dot notation
-at_path_compiled<Person, ".name">(doc)
-at_path_compiled<Person, ".address.city">(doc)
-
-// Bracket notation
-at_path_compiled<Person, "[\"name\"]">(doc)
-at_path_compiled<Person, "[\"address\"][\"city\"]">(doc)
-
-// Array access
-at_path_compiled<Person, ".emails[0]">(doc)
-at_path_compiled<Person, ".emails[1]">(doc)
-
-// Mixed notation
-at_path_compiled<Person, ".address[\"zip\"]">(doc)
-at_path_compiled<Person, "[\"emails\"][0]">(doc)
-
-// With root indicator
-at_path_compiled<Person, "$.name">(doc)
-at_path_compiled<Person, "$.address.city">(doc)
-```
-
-## JSON Pointer Syntax
-
-JSON Pointer (RFC 6901) uses slash-separated paths:
-
-### Supported Syntax
-
-| Syntax | Description | Example |
-|--------|-------------|---------|
-| `/field` | Field access | `/name`, `/address/city` |
-| `/index` | Array index | `/0`, `/1` |
-| `~0` | Escaped `~` | `/field~0name` → field~name |
-| `~1` | Escaped `/` | `/field~1name` → field/name |
-
-### Examples
-
-```cpp
-struct Car {
-  std::string make;
-  std::string model;
-  int64_t year;
-  std::vector<double> tire_pressure;
-};
-
-// Field access
-at_pointer_compiled<Car, "/make">(doc)
-at_pointer_compiled<Car, "/model">(doc)
-
-// Array access
-at_pointer_compiled<Car, "/tire_pressure/0">(doc)
-at_pointer_compiled<Car, "/tire_pressure/1">(doc)
-
-// Root pointer (returns whole document)
-at_pointer_compiled<Car, "">(doc)
-at_pointer_compiled<Car, "/">(doc)
-```
-
-## API Reference
-
-### JSONPath Functions
-
-```cpp
-// With type validation
-template<typename T, constevalutil::fixed_string Path, typename DocOrValue>
-simdjson_result<value> at_path_compiled(DocOrValue& doc_or_val);
-
-// Without validation
-template<constevalutil::fixed_string Path, typename DocOrValue>
-simdjson_result<value> at_path_compiled(DocOrValue& doc_or_val);
-```
-
-### JSON Pointer Functions
-
-```cpp
-// With type validation
-template<typename T, constevalutil::fixed_string Pointer, typename DocOrValue>
-simdjson_result<value> at_pointer_compiled(DocOrValue& doc_or_val);
-
-// Without validation
-template<constevalutil::fixed_string Pointer, typename DocOrValue>
-simdjson_result<value> at_pointer_compiled(DocOrValue& doc_or_val);
-```
-
-### Direct Field Extraction
-
-Extract values directly into variables with compile-time type checking:
-
-```cpp
-// JSONPath
-template<typename T, constevalutil::fixed_string Path>
-struct path_accessor {
-  template<typename DocOrValue, typename FieldType>
-  static error_code extract_field(DocOrValue& doc_or_val, FieldType& target);
-};
-
-// JSON Pointer
-template<typename T, constevalutil::fixed_string Pointer>
-struct pointer_accessor {
-  template<typename DocOrValue, typename FieldType>
-  static error_code extract_field(DocOrValue& doc_or_val, FieldType& target);
-};
-```
-
-**Example:**
-
-```cpp
-struct User {
-  std::string name;
-  int age;
-};
-
-ondemand::parser parser;
-auto doc = parser.iterate(json);
-
-// Extract directly into variable
-std::string name;
-ondemand::json_path::path_accessor<User, ".name">::extract_field(doc, name);
-
-int age;
-ondemand::json_path::pointer_accessor<User, "/age">::extract_field(doc, age);
-```
-
-The compiler verifies that the target variable type matches the field type at the path.
-
-## Complete Examples
-
-### Example 1: Validated Access
-
-```cpp
-#include "simdjson.h"
-using namespace simdjson;
-
-struct Car {
-  std::string make;
-  std::string model;
-  int64_t year;
-  std::vector<double> tire_pressure;
-};
-
-int main() {
-  const padded_string json = R"({
-    "make": "Toyota",
-    "model": "Camry",
-    "year": 2018,
-    "tire_pressure": [40.1, 39.9, 37.7, 40.4]
-  })"_padded;
-
-  ondemand::parser parser;
-  auto doc = parser.iterate(json);
-
-  // Type-validated access
-  std::string make;
-  auto result = ondemand::json_path::at_path_compiled<Car, ".make">(doc);
-  result.get(make); // make = "Toyota"
-
-  // Array access with validation
-  double pressure;
-  result = ondemand::json_path::at_path_compiled<Car, ".tire_pressure[1]">(doc);
-  result.get(pressure); // pressure = 39.9
-
-  return 0;
-}
-```
-
-### Example 2: Non-Validated Access
-
-```cpp
-#include "simdjson.h"
-using namespace simdjson;
-
-int main() {
-  const padded_string json = R"({
-    "user": {
-      "name": "Alice",
-      "preferences": {
-        "theme": "dark",
-        "notifications": true
-      }
-    }
-  })"_padded;
-
-  ondemand::parser parser;
-  auto doc = parser.iterate(json);
-
-  // No validation - works with any JSON structure
-  std::string_view theme;
-  auto result = ondemand::json_path::at_path_compiled<".user.preferences.theme">(doc);
-  result.get(theme); // theme = "dark"
-
-  bool notifications;
-  result = ondemand::json_path::at_path_compiled<".user.preferences.notifications">(doc);
-  result.get(notifications); // notifications = true
-
-  return 0;
-}
-```
-
-### Example 3: Direct Extraction
-
-```cpp
-#include "simdjson.h"
-using namespace simdjson;
-
-struct Person {
-  std::string name;
-  int age;
-  std::vector<std::string> emails;
-};
-
-int main() {
-  const padded_string json = R"({
-    "name": "Bob",
-    "age": 25,
-    "emails": ["bob@example.com", "bob@work.com"]
-  })"_padded;
-
-  ondemand::parser parser;
-  auto doc = parser.iterate(json);
-
-  // Extract with type validation
-  std::string name;
-  ondemand::json_path::path_accessor<Person, ".name">::extract_field(doc, name);
-  // name = "Bob"
-
-  int age;
-  ondemand::json_path::pointer_accessor<Person, "/age">::extract_field(doc, age);
-  // age = 25
-
-  std::string email;
-  ondemand::json_path::path_accessor<Person, ".emails[0]">::extract_field(doc, email);
-  // email = "bob@example.com"
-
-  return 0;
-}
-```
-
-## Error Handling
-
-Compile-time errors occur when:
-- Path doesn't exist in struct: `static_assert` failure
-- Field type mismatch: `static_assert` failure
-- Invalid array access on non-array field: `static_assert` failure
-
-Runtime errors occur when:
-- JSON structure doesn't match expected structure
-- Array index out of bounds
-- Type conversion failures
-
-```cpp
-struct User {
-  std::string name;
-  int age;
-};
-
-// Compile-time error: no "email" field in User
-// auto result = ondemand::json_path::at_path_compiled<User, ".email">(doc);
-
-// Compile-time error: age is not an array
-// auto result = ondemand::json_path::at_path_compiled<User, ".age[0]">(doc);
-
-// Runtime error if JSON doesn't have "name" field
-auto result = ondemand::json_path::at_path_compiled<User, ".name">(doc);
-std::string name;
-if (result.get(name) != SUCCESS) {
-  // Handle error
-}
-```
-
-## Performance
-
-Compile-time accessors provide:
-- **Zero path parsing overhead** - paths parsed at compile time
-- **Zero validation overhead** - validation done at compile time
-- **Direct field access** - no runtime path traversal
-- **Type-safe extraction** - no dynamic type checking
-
-Compared to runtime `at_path()` and `at_pointer()`:
-- Eliminates runtime path string parsing
-- Eliminates runtime path validation
-- Generates optimal code path directly
-
-## Limitations
-
-- Requires C++26 compiler with P2996 support (experimental)
-- Paths must be compile-time constants (string literals)
-- Cannot use runtime-computed paths
-- Limited to struct types that support reflection
-- Array indices must be compile-time constants in the path
-
-## When to Use
-
-**Use compile-time accessors when:**
-- You have well-defined struct types
-- JSON structure is known at compile time
-- You want maximum type safety
-- Performance is critical
-
-**Use runtime `at_path()`/`at_pointer()` when:**
-- JSON structure varies or is unknown
-- Paths are computed at runtime
-- Working with C++20 or earlier
-- Flexibility is more important than compile-time checks

 The Basics: Loading and Parsing JSON Documents using the DOM front-end
 ----------------------------------------------
 
 The simdjson library offers a simple DOM tree API, which you can access by creating a
 `dom::parser` and calling the `load()` method:
 
-```cpp
+```c++
 dom::parser parser;
 dom::element doc = parser.load(filename); // load and parse a file

 SIMDJSON_PADDING bytes at the end) and calling `parse()`:
 
-```cpp
+```c++
 dom::parser parser;
 dom::element doc = parser.parse("[1,2,3]"_padded); // parse a string, the _padded suffix creates a simdjson::padded_string instance
 ```
 
-You can also load a `padded_string` from a file.
-
-
-```cpp
-auto json = padded_string::load("twitter.json"); // load JSON file 'twitter.json'.
-dom::element doc = parser.parse(json);
-```
-
-[You can similarly fetch a file from a URL to a padded string](https://github.com/simdjson/curltostring) using our `simdjson::padded_string_builder`.

-
-
-(Windows users compiling with C++17 or better may use `wchar_t` strings to support non-ASCII
-filenames: `padded_string::load(L"twitter.json")`.)

 You can copy your data directly on a `simdjson::padded_string` as follows:
 
-```cpp
+```c++
 const char * data = "my data"; // 7 bytes
 simdjson::padded_string my_padded_data(data, 7); // copies to a padded buffer
 ```
 
 Or as follows...
 
-```cpp
+```c++
 std::string data = "my data";
 simdjson::padded_string my_padded_data(data); // copies to a padded buffer

-You can then parse the JSON document from the `simdjson::padded_string` instance:
-
-```cpp
-simdjson::dom::parser parser;
-simdjson::dom::element doc = parser.parse(my_padded_data);
-```
-
-Whenever you pass an `std::string` reference to `parser::parse`,
-the parser will access the bytes beyond the end of
-the string but before the end of the allocated memory (`std::string::capacity()`).
-If you are using a sanitizer that checks for reading uninitialized bytes or `std::string`'s
-container-overflow checks, you may encounter sanitizer warnings.
-You can safely ignore these warnings. Or you can call `simdjson::pad(std::string&)` to pad the
-string with `SIMDJSON_PADDING` spaces: this function returns a `simdjson::padding_string_view` which can be be passed to the parser's iterator function:
-
-```cpp
-std::string json = "[1]";
-dom::element doc = parser.parse(simdjson::pad(json));
-```
-
 The parsed document resulting from the `parser.load` and `parser.parse` calls depends on the `parser` instance. Thus the `parser` instance must remain in scope. Furthermore, you must have at most one parsed document in play per `parser` instance.

   The strings contain unescaped valid UTF-8 strings: no unmatched surrogate is allowed.
-  Internally, numbers are stored as either 64-bit integers or 64-bit floating-point numbers.
-  Thus it is possible to get the full 64-bit integer range (either signed or  unsigned).
-  By default, the string `-0` is parsed as the integer 0 as in Python or C++. If you set the macro
-  `SIMDJSON_MINUS_ZERO_AS_FLOAT` to `1` when building simdjson, you can get that `-0` is mapped to `-0.0`
-  as in JavaScript. You can get the desired effect by building simdjson with cmake setting the
-  `SIMDJSON_MINUS_ZERO_AS_FLOAT` to on: `cmake -B build -D SIMDJSON_MINUS_ZERO_AS_FLOAT=ON`.
-* **Big Integer Support (opt-in):** By default, integers that exceed the 64-bit range cause parsing to fail with `BIGINT_ERROR`. You can opt in to big integer support so that these numbers are stored as raw digit strings on the tape instead:
-  ```cpp

-## Using `at_path_with_wildcard` for JSONPath Queries
-
-The `at_path_with_wildcard` function in simdjson extends the JSONPath querying capabilities by supporting wildcard expressions (`*`) in JSON paths. This allows users to retrieve multiple elements from a JSON document in a single query. For example, you can use `$.address.*` to fetch all fields within the `address` object or `$.phoneNumbers[*].numbers[*]` to retrieve all phone numbers across multiple objects in an array.
-
-The `*` wildcard matches all elements at a specific level. For instance, `$.address.*` retrieves all key-value pairs in the `address` object, while `$.*.streetAddress` fetches all `streetAddress` fields across objects at the root level.  You can combine wildcards with array indexing. For example, `$.phoneNumbers[*].numbers[1]` retrieves the second number from each `numbers` array in the `phoneNumbers` array. If no elements match the wildcard query, the function returns an empty result. For instance, querying `$.empty_object.*` or `$.empty_array.*` will yield an empty set.
