After upgrading g++ package to 12.1.0 on archlinux I see the following
compilation error:
/usr/include/argparse/argparse.hpp: In member function ‘void argparse::ArgumentParser::index_argument(list_iterator)’:
/usr/include/argparse/argparse.hpp:1167:34: error: ‘as_const’ is not a member of ‘std’; did you mean ‘is_const’?
1167 | for (const auto &name : std::as_const(it->m_names)) {
| ^~~~~~~~
| is_const
It turns out that std::as_const comes from <utility> header [1] which
was not explicitly included.

As far as I can tell, this statement is never true.
When m_values.size() < *expected, ::consume has already thrown "Too few
arguments..." before ::validate is called.
When m_values.size() > *expected, ArgumentParser::parse_args_internal
has already thrown "Maximum number of positional arguments exceeded"
before ::validate is called.
If ::remaining is used to avoid the last exception, this Argument will
always consume the expected number of values, hence this expression is
again false.

This regression was caused by commit
ea1f7ef663, which didn't add "\n" to the
version printing statement. We use std::endl now for compatibility
across platforms.
I am seeing too many errors due to bad tool configuration, not from
problems in project code. So, disable SA until I can make it work more
reliably.

The 'unused' variable in both cases is most-definitely unused in the loop.
This is a cppcheck warning that appeared after moving these two loops to
range-for.

This code was previously moved from ::parse_args to its own method, but
has since been simplified. Moving the actual work to Argument::validate
in commit 603e87ae6 leaves a single loop that fits back into ::parse_args.

The new naming pattern is CamelCase for structs, except parse_number as a
primarily callable interface. Trait structs are named Has*Traits
and constexpr variables to the struct template are named Is*.

Most changes are to better fit within "ColumnLimit: 80".
The change from "T &&... var" to "T &&...var" is caused by
"PointerAlignment: Right".
Member functions chained from add_argument() use ContinuationIndentWidth,
which is set to 4. Setting ContinuationIndentWidth to 2 causes many
other continuation lines to change. So, this commit uses the original
value (i.e. 4) as the preferred size.

The "Cpp11" alias is deprecated for Latest (a rolling standard). For now,
stick to C++17.

Also converts most C-style arrays to a std::array onjects. The check is
disabled for ArgumentParser::parse_args(int, const char *const[]) as this
is a helper function to convert away from a common input format.

The two functions previously flagged by this check,
Argument::is_decimal_literal and Argument::validate, fell below the
default Cognitive Complexity threshold as a result of the branch
simplification for the readability-else-after-return check.

A common pattern in the previous code was goto/return/throw if a condition
is true, else goto/return/throw something different. The new pattern
uses the fact that the second goto/return/throw is only reachable when the
first goto/return/throw is not called.

Following the clang-tidy suggested fix in consume_digits causes compile

Adds names recommended by clang-tidy (e.g. "unused").
Note that clang-tidy v12 appears to detect unnamed parameters in lambdas,
while clang-tidy v13 does not.

Enabling this check caught the implicit bool conversion with
default_arguments::operator& fixed in the previous commit.

operator& should return combined values of the same type, not a new type
(i.e. bool). This is much more verbose, but easier to reason about
without implied conversion.

Upstream StaticAnalysis looks to be changing for more flexibility with
source files to process. While these changes may eventually benefit
argparse, the public interfaces are in flux and we need a stable tool.
argparse also needs a SA change which is not yet upstream.
Trying to run clang-tidy via StaticAnalysis on a single file in a
directory with many source file is not easy, so move the analysis kernel
to a location (i.e. tools) where it is the only C++ source file.
Another benefit is cppcheck no longer needs to be told to ignore the test
sources.
