1.4.2

Binary format improvements for the format now known as BEVE

• Added proper skipping to binary, allowing error_on_unknown_keys to be false
• std::complex handling for binary

JSON

• more rvalue object reading support
• fixed write_file_json API in json_exceptions.hpp

1.4.1

Fixes:

• Properly erroring for invalid Enum keys

New Features:

• Added custom_read and custom_write flag support to glz::meta, which can solve ambiguous partial template specialization (see custom-serialization.md)
• Added error_on_const_read compile time option to glz::opts, which will produce errors if an attempt is made to read into a const value (the default behavior is still to skip the value)

Internal Improvements:

• Using .erase rather than .resize where appropriate when reducing lengths of array like types

1.4.0

BREAKING JSON RPC 2.0 interface changes:
rpc::server_method_t and rpc::client_method_t have been replaced with a single rpc::method type.
rpc::json_rpc_t has been replaced with rpc::id_t

• Significant JSON RPC 2.0 code cleanup, with some performance improvements
• Fixed long 0.000... float reading
• Thread pool (glz::pool) cleaning and internal improvements

1.3.6

JSON

• Safer buffer resize (avoids issues if buffer is of zero length)
• Support for raw buffers in write_as_json
• name_v fix for long long and unsigned long long (Thanks @jbbjarnason)
• Fix the counting of json array elements when the element type is object or array (Thanks @huangminghuang)

Binary

• Significant binary format changes to support latest EVE specification
• Faster and cleaner binary format code
• write_file_binary supports more buffer types
• New binary matrix format handled with Eigen

1.3.5

• Removed undefined behavior with page boundary checking (fixes address sanitizer complaints)
• Much safer integer parsing, with underflow and overflow checking
• Removed deprecated file writing functions
• Removed some unnecessary <iostream> includes for smaller sizes on embedded devices

1.3.4

Fixes

• Negative numbers when attempting to parse into unsigned integers are now properly errors
• Integer types with sizes less than 8 bytes (int8_t, int16_t, int32_t, etc.) are now checked for overflow and underflow against a parse into an int64_t or a uint64_t, depending on whether signed or unsigned
• Fixed glz::merge for nested object types
• Removed a bad noexcept for glz::ex::read_json

New Features

• Added glz::obj_copy and glz::arr_copy, which behave like glz::obj and glz::arr, but copy state (these structures are for logging JSON)
• Added CSV writing for glz::recorder

Cleanup

• Eliminated unnecessary thread_local for set reading
• Removed an unnecessary #include <iostream>

1.3.3

• Fixed writing out objects within glz::obj and further nesting
• Fixed serializing maps that skip nulls (Thanks @justend29)
• Removed now unnecessary MSVC specific code

1.3.2

• Significantly increased JSON schema support (glz::schema can be passed in the place of comments in glz::meta) (Thanks @jbbjarnason)
• Better support for std::string_view as map key type
• More efficient std map type handling (especially of non-string keys, which are quoted) (Thanks @SlaaneshChosen)
• Fixed support for glaze enum keys in map types (e.g. std::map<MyEnum,...>)

1.3.1

• Added glz::merge, which allows users to merge JSON object types (suggested by @GJanos)

glz::obj o{"pi", 3.141};
std::map<std::string_view, int> map = {{"a", 1}, {"b", 2}, {"c", 3}};
auto merged = glz::merge{o, map};
std::string s{};
glz::write_json(merged, s); // will write out a single, merged object
// s is now: {"pi":3.141,"a":0,"b":2,"c":3}

• Fixed null char* issues and added better concepts for char array handling (Thanks @maor-da)
• Fixed std::max/std::min macro issues with MSVC (Thanks @alfedotov)

1.3.0

BREAKING v1.3.0 CHANGE: std::pair is now handled as a JSON object ({"first":second}}. If you require a JSON array of two items, use std::array or std::tuple.

Removed MSVC 2019 support (the compiler has too many limitations for ranges and compile time logic)

• Added numeric enum support (default behavior)
• std::string reading with CSV format
• Added separate concepts for readable_map_t and writable_map_t (thanks @justend29)
• Views and ranges of std::pair can now be serialized as objects: (thanks @justend29)

auto num_view =
std::views::iota(-2, 3) | std::views::transform([](const auto i) { return std::pair(i, i * i); });
expect(glz::write_json(num_view) == glz::sv{R"({"-2":4,"-1":1,"0":0,"1":1,"2":4})"});

• Added glz::invoke and glz::invoke_update, which allow invoking functions when reading JSON input
• Added GLZ_QUOTED_X helper macro (thanks @pwqbot)
