* refactor: emplace logic to use do_emplace for in-place construction with forwarded arguments #1493
* Add test for variant_variadic

active_list.remove(id, has_expired) adjusts the next timer's delta only
when has_expired is false. When unregistering an active, non-expired timer,
unregister_timer() incorrectly passed true, skipping that adjustment, so
every timer after the removed one in the active list fired early by the
removed timer's delta.
Pass false instead, matching the etl::callback_timer family. tick() still
passes true, since the timer has genuinely expired there. The bug affected
all four variants: message_timer, message_timer_interrupt,
message_timer_atomic and message_timer_locked. Existing tests missed it
because they only ever unregistered the tail timer, where the delta
adjustment is a no-op.
Add a regression test that unregisters a non-tail active timer and checks
the following timer still fires at its original absolute time.
* Drop problematic `T& emplace(const optional_impl& other)`
- Ror both fundamental and non-fundamental specializations.
- This also fixes incorrect `return storage.u.value;` in the fundamental specializations.
- Simplify `emplace` overloads (drop SFINAE).
- Update test cases to:
- verify returned reference
- verify `nothrow`
- Add `emplace(std::initializer_list, ...)` overload for non-fundamental types.
* Fix clang-format
* Revert to idiomatic C++ `initializer_list` by-value.
* feat: Add constexpr support for delegate construction and assignment in C++14 and C++20
* docs: add more docstring coverage #1473
* docs: note constexpr availability for function-pointer overloads
Update docs/callbacks/delegate.md to reflect the new ETL_CONSTEXPR14
annotations on delegate(function_ptr) and create(function_ptr), and add
a paragraph to the Constexpr section explaining which function-pointer
APIs are usable in constant expressions at C++14 vs C++20.

* Fix etl::get to preserve reference members for tuple rvalues
The rvalue-qualified overloads of etl::get (both the index-based and
type-based forms) unconditionally applied etl::move to the stored
element. For a tuple holding a reference member (e.g. etl::tuple<int&>),
this cast the referenced object to an rvalue instead of returning the
stored lvalue reference, diverging from std::get and failing to compile
when the result was bound to a non-const lvalue reference.
Forward the element with static_cast<element_type&&> instead, so that
reference members collapse to an lvalue reference while value members are
still moved. This is required to support tuples of references such as
those produced by the zip, enumerate and adjacent views.
* Make ranges views return non-const references to make them mutable
* Support type-changing transform_view
* Fix join_with_iterator reference type to match operator*
join_with_iterator declared reference = inner_trait::reference (e.g. int&)
while operator* returns value_type by value. For prvalue-yielding inner
ranges (e.g. repeat_view from a type-changing transform) the declared
reference was inconsistent with the actual dereference. Derive value_type
from the inner iterator's dereference and set reference = value_type,
preserving by-value semantics.
Add regression test for transform|join_with with prvalue inner ranges.
* Make join_with conform to [range.join.with.iterator] using inner/pattern common reference
* Clang-format
* Fix owning_view const begin()/end() by making _r mutable so chunk_view compiles over rvalue ranges
Some ETL random tests write to files but don't CHECK() anything.
Since they are left at the file system and were only used during
development, they can be removed now.

Before, libstdc++ was used in both gcc and clang builds.
Fix includes an adjustment to consider in NO_STL case.
Now build with libc++ in separate github workflows with clang.
* Fix iterator access algorithm.h
Move from operator[] access to operator+ and operator- to prevent
limited compatibility. This worked before for vector because of
iterators being ptrdiff_t (signed), but not for unsigned access
like size_t as in etl::queue.

* Fix copy and move in signal.h
* Delete copy and move in callback_service.h
The implicitly provided copy and move copied internal pointers
which are invalid after copying.
* Delete copy and move in delegate_service.h
The implicitly provided copy and move copied internal pointers
which are invalid after copying.
* Add more constexpr to ctors
* Adjust operator!=() in fixed_iterator.h
Instead of taking an iterator by reference, take it by value as
done in the other operators and overloads.
* Initialize move_iterator() current member
Prevent indeterminate values
* Fix fixed_iterator::operator* return type
fixed_iterator::operator* returned value_type by value, so writes like *it = ...
modified a temporary rather than the underlying location. This broke the
iterator’s intended use (e.g., writing to a fixed register/memory location).
Now returning iterator_traits<TIterator>::reference instead (const and
non-const overloads).
* Fixed move_iterator::operator+= and operator-= return type
move_iterator::operator+= / operator-= returned by value, but RandomAccessIterator
requirements (and std::move_iterator) expect these to return move_iterator&.
Returning by value also added an unnecessary copy and could break generic code
expecting reference semantics.
* Print test names at test time (#1343)
* Fix operator| conflict with std::ranges (#1395)
* Added etl::intrusive_avl_tree class.
* PR review minor fixes.
* Fix `std::move` -> `etl::move`
* Apply AI spell checking
* Try to fix C++03 build.

The primary etl::iterator_traits template previously required all five
nested typedefs (iterator_category, value_type, difference_type,
pointer, reference) to exist, causing hard compilation errors with
iterators like std::common_iterator or ranges::common_iterator.
Changes:
1. Make primary template SFINAE-friendly: split into an empty primary
template and a void_t-guarded partial specialization that only
activates when all nested typedefs are present.
2. Add explicit std::common_iterator specialization (C++20/STL): a
partial specialization that delegates to
std::iterator_traits<std::common_iterator<I,S>>.
3. Fall through to std::iterator_traits: the empty primary template
inherits from std::iterator_traits<TIterator> when building with
STL and C++20, so any iterator with a std::iterator_traits
specialization works automatically.
4. Remove iterator_traits dependency from etl::vector: assign() now
uses decltype(*first) for the type-compatibility static assert,
and insert() uses ptrdiff_t directly instead of querying
iterator_traits<TIterator>::difference_type.
format.h:
- Fix float zero-padding ({:010f}): output sign first, then zero-fill,
then the unsigned formatted value, matching std::format behavior.
- Fix nested replacement fields ({:{}d}): consume the value's auto-index
in parse_format_spec before parsing nested width/precision fields, so
auto-indexing order matches the C++ standard.
- Fix {:#o} with value 0: produce "0" instead of "00" by skipping the
octal prefix when the value is zero.
- Fix format_floating_default overflow for extreme doubles (DBL_MIN,
DBL_MAX): fall back to scientific notation for values >= 1e18 or
tiny positives < 1e-6, delegating to format_floating_e.
- Fix format_floating_e precision loss: replace iterative multiply-by-10
normalization loop with O(1) log10/pow/floor computation.
- Add resolve_nested_replacements helper to extract width/precision
from format args at formatting time.
test_format.cpp:
- Add tests for float zero-padding, nested replacement width, octal
alternate form with zero, float sign/width/alignment, negative floats,
scientific notation for large/small values, default-to-scientific
switch, positive zero, brace escaping, and integer limits.
format.h + platform.h:
- log10l fix for different toolchain support:
Define ETL_FORMAT_NO_LONG_DOUBLE_MATH in the profile if libm doesn't
provide log10l. This is identified by linker error missing this symbol.
It was identified with the llvm/clang cross toolchain for ARM.
* Print test names at test time (#1343)
* Fix operator| conflict with std::ranges (#1395)
* added Pico and additional Teensy defines

* Print test names at test time (#1343)
* Fix operator| conflict with std::ranges (#1395)
* Fix the case of using STL without pthreads but with mutexes
On non-POSIX targets in STL mode, std::mutex is included from
mutex.h but will probably miss pthreads. Instead, other
implementations might be detected and used in mutex.h.
Therefore, adding ETL_NO_STD_MUTEX as a profile option for ETL.
Further, removing unnecessary includes from queue headers.
