* Initial work on JSON builder * moving the files back to ondemand for now. * tweak * more later * update * minor edits * dropping vs arm (missing support) * adding tests. we still specialized write_string_escaped * tweaking * fix typo * tweaking the approach * minor fix * missing store * another missing store * Attempt at fixing failing serialization tests. (#2292) * Fixing appeand_float typo (#2294) * applying a couple of fixes * updating single header * fix for pre C++17 if constexpr * Fixing unused argument problem and updating the singleheader file * various pedantic fixes * Sketch of builder * reordering. * simplify * Adding draft of static reflection based deserialization * Updating simdjson singleheader * patching the automated deserialization. * automated * Adding support for smart pointers of user defined types. * Adding specialization for smart pointers for basic types. I think it is highly likely that this can be done in a more generic way. * Referncing a later version of rapidjson that fixed the issue related with assignment attempt of a const variable for GenericStringRef class. * guarding the tests * adding documentation for string_builder * saving * rename to 'append' * saving * non-functional benchmarks (#2342) * non-functional benchmarks * Fix typo * various fixes * tweaking --------- Co-authored-by: Daniel Lemire <dlemire@lemire.me> Co-authored-by: Francisco Geiman Thiesen <franciscogthiesen@gmail.com> * tuning * various minor fixes * minor tweak * minor simplification * updating amal * adding a cast * update * fancy casting * removing dead code * Pushing latest changes. CITM benchmark is still not working. * Still not working, but now I am getting only 10 errors. * add static reflection benchmark to 'large random' benchmark and allows (#2349) deserialization (with static reflection) from objects and arrays. Co-authored-by: Daniel Lemire <dlemire@lemire.me> * Removing std::map from CitmCatalog definition, since that is not currently supported. * Added free to rust bench, segfault is still happening.. * The syntax changed: ^E became ^^E. (#2350) * The syntax changed: ^E became ^^E. * guarding --------- Co-authored-by: Daniel Lemire <dlemire@lemire.me> * Adding support for string_view_keyed_map types. * Adding concepts as a conditional include. * updating single-header * Adding concepts to ondemand deps * rust benchmark is finally working * Fixing small typo in docs. * adding docker config and instructions so that our users can test the static reflection (#2358) * adding docker config and instructions so that our users can test the static reflection * completing the instructions * pruning white spaces --------- Co-authored-by: Daniel Lemire <dlemire@lemire.me> * minor optimizations on the JSON builder branch * avoiding undef behaviour * saving * somewhat nicer builder * make it possible to run just one benchmark * adding linux perf * fixing minor issue * updating swar * Adding real world compilation benchmark (#2379) * Adding compilation benchmark for json parsing with and without reflection * Moving it to the benchmark folder, also reducing a bit the number of iterations. * Removing script from root folder. * Reducing number of iterations * Update benchmark/benchmark_reflection_usage_compilation.sh Co-authored-by: Daniel Lemire <daniel@lemire.me> * Update benchmark/benchmark_reflection_usage_compilation.sh Co-authored-by: Daniel Lemire <daniel@lemire.me> * Update benchmark/benchmark_reflection_usage_compilation.sh Co-authored-by: Daniel Lemire <daniel@lemire.me> * Making the script more customizable and also test whether the compiler being used supports reflection before actually running the benchmark --------- Co-authored-by: Daniel Lemire <daniel@lemire.me> * Using define_static_string from https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2025/p3491r2.html (#2389) * Applying changes needed after latest reflection paper updates. * Working, but no template for yet. * Updating single-header to incldue the use of define_static_string. * copying over master --------- Co-authored-by: Daniel Lemire <dlemire@lemire.me> Co-authored-by: Francisco Geiman Thiesen <franciscogthiesen@gmail.com>
