Pass a mutable buffer from the caller, and allow
PHYSFSX_addRelToSearchPath to adjust the capitalization in that buffer,
rather than creating a copy in a stack local. This can slightly affect
status messages that use the name, but otherwise should have no effect
on the game.
OS X still uses clang-14, which lacks sufficient std::ranges support for
recent Rebirth changes.
- Rewrite uses of std::ranges::SYMBOL to ranges::SYMBOL
- Add a stub header that, on gcc, provides for each SYMBOL a statement
`using std::ranges::SYMBOL;`, to delegate back to the standard library
implementation.
- On clang, define a minimal implementation of the required symbols,
without constraint enforcement. Compile-testing with gcc will catch
constraint violations.
Once OS X clang ships a standard library with the required features,
this stub header will be removed and the uses changed back to their full
names.
std::ranges::find_if permits use of a sentinel instead of a full
iterator, and supports std::ranges::find as an alternative to certain
simple uses of std::find_if.
Where possible, use the form that takes a range, rather than the form
that takes two iterators.
Add a declared, but not defined, default constructor for
self_return_iterator to satisfy the standard library's concept
`semiregular`, which insists that sentinels be default-constructible,
even for those functions that never need to do so.
Add a defined, but unused, operator++(postfix) for zip_iterator to
satisfy a standard library concept for `forward_iterator`.
Adjust code_window_point to use the same masks as clipping_code.
Previously, it had top and bottom swapped. However, since its output
was only ever compared for equality to 0, this transposition should not
affect the observable behavior.
Remove the definition of FQ_CHECK_OBJS and all uses of it. Add a new
fvi_query member d_level_unique_object_state *LevelUniqueObjectState.
If object checking is enabled, pass &LevelUniqueObjectState in that
member. If object checking is disabled, pass nullptr in that member.
Change fvi_sub to use this member to decide whether to perform object
checking.
- Make all members constant, and pass an anonymous temporary fvi_query
to find_vector_intersection.
- Change `p0`/`p1` to `const vms_vector &`, since the positions are
mandatory. Callers can no longer pass `nullptr` or an uninitialized
value here.
- Change `thisobjnum` to `icobjptridx_t`. Calls to fvi_sub built an
objptridx at need, so moving it to the caller allows it to be
constructed once per find_vector_intersection call.
- Move `flags` and `rad` out of fvi_query, since calls to fvi_sub may
use other values than the ones in fvi_query. This prepares for
passing fvi_query to fvi_sub.
splitpath_t is designed for MS-DOS paths, even though Rebirth now runs
on many platforms that never used DOS conventions. Most of the members
of splitpath_t are unused on all platforms. Remove them, and switch to
returning an initialized version of the structure.
If two or more events are delivered in the same loop, the previous
implementation would count joystick motion multiple times. Fix this by
moving the joystick interpretation to occur once, after all the events
have been processed.
Iterating over it returns each side number in turn. This allows
converting many loops of the form:
```
for (int i = 0; i < MAX_SIDES_PER_SEGMENT; ++i)
```
to the compact form:
```
for (const auto i : MAX_SIDES_PER_SEGMENT)
```
The compact form brings the usual benefit of range-based for: delegating
iteration to the compiler prevents the loop body from skipping a step,
and makes clear in the code that this is the case.
