 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.

+## Using `for_each_at_path_with_wildcard` for JSONPath Queries (On-Demand)

-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 `for_each_at_path_with_wildcard` function in simdjson extends the JSONPath querying capabilities by supporting wildcard expressions (`*`) in JSON paths. It calls a user-provided callback for each matching element, avoiding the need to materialize all results into a vector. 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 `$.empty_array.*` will yield an empty set.
+The `*` wildcard matches all elements at a specific level. For instance, `$.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 callback is simply never called. For instance, querying `$.empty_object.*` or `$.empty_array.*` will yield no callbacks.

 Performance consideration: We store numbers of the main tape because we believe that locality of reference is helpful for performance.

+## Big Integers
+
+When a JSON integer exceeds the 64-bit range (both signed and unsigned), it is classified as a big integer. By default, parsing returns `BIGINT_ERROR`. When `parser.number_as_string(true)` is set, the raw digits are stored on the string tape using the same format as strings (4-byte little-endian length prefix, followed by the UTF-8 digit bytes, followed by a null terminator).
+
+A big integer is represented on the main tape as the 64-bit tape element `('Z' << 56) + x` where the payload `x` is the location on the string tape of the null-terminated digit string.
+
+For example, the JSON value `99999999999999999999` would be stored as the string `"99999999999999999999"` on the string tape, with a `'Z'` tag on the main tape. Negative big integers include the leading minus sign.

Eyüp Can Akman	12fb30ae9c	add get_int32() and get_uint32() to the On Demand API (#2638 ) * add get_int32() and get_uint32() to the On Demand API Add convenience methods that call get_int64()/get_uint64() and range-check the result, returning NUMBER_OUT_OF_RANGE on overflow. Added to value, document, document_reference, and their simdjson_result wrappers. Closes #1890 * fix document_reference streaming for get_int32/get_uint32 The document_reference getters delegated to document::get_int32/get_uint32 which call get_root_int64/get_root_uint64 with allow_trailing_content=true, rejecting the next document in a stream as trailing content. Call get_root_value_iterator().get_root_int64/get_root_uint64(false) directly to allow trailing content, matching get_int64/get_uint64. Add streaming tests for both getters. * add get_int32/get_uint32 to basics.md * add get_int32/get_uint32 to wrong-type error tests * add get<uint32_t>/get<int32_t> template specializations Wire the 32-bit getters into the generic get<T>() and get(T&) dispatch so that doc.get<uint32_t>() compiles on C++11/14/17 without requiring the C++20 concepts path in std_deserialize.h.	2026-03-30 10:16:31 -04:00

harshanagd	bddb23177e	feat: Add DOM tape support for big integers (opt-in) (#2640 ) When parser.number_as_string(true) is set and a number exceeds uint64 range, write the raw digits to the string buffer and emit a BIGINT ('Z') tape tag instead of returning BIGINT_ERROR. Default behavior unchanged. Changes: - tape_type.h: add BIGINT = 'Z' - dom_parser_implementation.h: add _number_as_string flag - parser.h: add number_as_string() getter/setter - parser-inl.h: propagate flag before parse - tape_builder.h: visit_number checks flag on BIGINT_ERROR - tape_writer.h: add append_bigint helper - serialization-inl.h: handle BIGINT in serialization (raw digits) - tape.md: document big integer tape format Builds on PR #2139 which added BIGINT_ERROR detection.

Levi Zim	a1ff05a5e8	Fix RISC-V compilation without RVV (#2637 ) #2617 introduced an RVV check that only checks if the compiler supports RVV intrinsics without checking if RVV is enabled at compile time. This has caused compilation failure of node.js on riscv64. Fix it by appending a check for __riscv_vector.	2026-03-20 11:11:38 -04:00
