v0.8.2

v0.8.2 - 10DEC24

Added Features

• #70 CMake compiler option macro helper
• #69 get<T>(tuple) now available
• #58 ESP-IDF logging emulation

Quality Updates & Bug Fixes

• #68 freertos::wrapper::task::create_static now truly calls xTaskCreateStatic
• #66 tuple.visit() now works with references too

v0.8.1

v0.8.1 - 31OCT24

Added Features

• estd::num_put for bools & integers now available
  • Supports foreign locales, encodings, 16 bit characters and more
  • Compile-time tuning options
• estd::variadic::values gets where and contains()
• #49 rudimentary byteswap
• #51 enhanced operators for units
• #53 function_traits now active

Known Issues & Limitations

• A full num_put is extensive functionality. Currently unsupported are floats, comma and decimal placement

Quality Updates & Bug Fixes

• #48 more flexible span constructor
• basic_ispanbuf and friends promoted from experimental to estd

v0.8.0

Added Features

• Adding simplistic beta-quality memory pool. Located in estd::internal::memory::pool
• Adding make_heap, push_heap and pop_heap

Quality Updates & Bug Fixes

• #40 Fixed glitch in Streambuf c++20 concept
• #39 Upgraded & cleaned out internal detail::function
• AVR pgm support additional testing & refinement
• Dogfooding internal units code into chrono support
• Fixed glitch in variadic::values when using non-integer types

Known Issues & Limitations

• Our heapify functions are crude and won't be as optimized as std.
  Still, it's better than nothing

v0.7.2

Quality Updates & Bug Fixes

• #35 Top-level CMakeLists.txt now usable
• Massive cleanup of estd/limits.h:
  • #36 fixed type_traits dependency
  • #37 Deducing long long far more effectively now

v0.7.1

Added Features

• #31 Added estd::detail::iostream
• #34 Added uint_least64_t and some other numeric_traits related goodies

Quality Updates & Bug Fixes

• Improved clang compatibility, especially with c++20 concepts and bipbuffer
• Fixed bug: 64-bit numeric_limits sometimes resolved to 32-bit
• #24 Switched default size_type of strings from int16 -> size_t (can still override with policy)
• #32 Fixed various tuple::visit edge cases
• #33 Fixed minor glitch with dec, hex manipulator dependencies

v0.7.0

Added Features

• estd::tuple now can operate in sparse mode, meaning it can fold down to 0 size if all its members are also 0 size.
• Wrapping willemt's awesome bipbuffer as layer1::bipbuf and layer3::bipbuf
  • See https://www.codeproject.com/Articles/3479/The-Bip-Buffer-The-Circular-Buffer-with-a-Twist

Added Features (internal)

Early access - marked internal mainly due to naming and API flux, but passes tests:

• Added out_buffered_stringbuf and out_bipbuf_streambuf wrapper for "true" streambuf operations. These sit in front of a raw streambuf for additional caching.
• Core units capability - including bytes and percent and SI helpers for converting to string

Quality Updates & Bug Fixes

• Bringing back c_str() to layer1 and layer2 strings
• Various AVR and estd::variadic cleanup
• Fixed bug in to_chars (#28)

v0.6.2

Added Features

• Formally an esp-idf component now
• Adding floating point support to num_get
• Formalizing estd::detail::to_chars, an even lower-level interpretation of to_chars

Quality Updates & Bug Fixes

• Using CMake's FetchContent now to acquire unit test frameworks rather than submodules
• Minor breaking change: selector disambiguation
  • v1 namespace - "selector" might mean API to select or result of selecting
  • v2 namespace - "selector" only means API to select
• Fixed bug where hex 'a' was encoded incorrectly during to_chars

Known Issues & Limitations

• from_chars doesn't yet get floating point, even though num_get does

v0.6.1

Added Features

• estd::detail::string is a more manageable way to pass strings around
• Experimental/partial support for AVR PGM strings: estd::v0::avr::pgm_string

Quality Updates & Bug Fixes

• estd::tuple now has conversion constructor
• estd::variant on AVR now usable, with caveats (see next section)
• String support code got a major scrub, though still a lot of crust in there
• estd::vector no longer does naughty memmove with non-trivial types

Known Issues & Limitations

• estd::is_constructible is broken on AVR. Possibly this is due to -fpermissive default flag
• estd::variant on AVR caveats:
  • Using is_convertible rather than is_constructible, for assignment
    operator, so your mileage may vary when using more exotic types and constructors
  • is_constructible being how it is may negatively affect other areas. So far unit tests are OK though.
  • move semantic seems glitchy, destructs don't seem to get called

v0.6.0

NOTICE: License changed from MIT to APACHE 2.0

Added Features

• Added estd::variant
• Added estd::variadic namespace
  • variadic::types for compile-time management of class ...Types
  • variadic::values for compile-time management of T ...Values (overlaps with estd::index_sequence)
  • variadic::selector for compile-time evaluation of class ...Types
  • variadic::visitor for runtime visitor pattern applied to class ...Types
• Added ESTD_VERSION macro for compile-time version query

Quality Updates & Bug Fixes

• is_base_of no longer caught up on access modifierrs
• General Arduino, AVR, c++03 compatibility
• estd::optional and estd::expected much more robust
  • shares code base with estd::variant
  • when available, exceptions are now supported
• estd::num_get and by extension istream integer parsing now returns min/max value on overflow
• estd::priority_queue works on more targets

Known Issues & Limitations

• estd::variant not functional on AVR, probably bugs in #7

v0.5.1

Added Features

• Adding setw and setfill to ostream
• Adding estd::expected and estd::unexpected

Quality Updates & Bug Fixes

• Fixing signed/unsigned mismatch in out_span_streambuf
• Fixing estd::optional bug when using reset on enum type
• Adding edge case optimization to estd::tuple (see FEATURE_ESTD_SPARSE_TUPLE)

Known Issues & Limitations

• estd::expected:
  • Not well tested outside of c++11 GCC, though designed to be compatible with c++03
  • Various edge cases like returning && value() not yet implemented
