... Unnecessary because transitively included.
But each .cpp file still includes its own .h file near the top to ensure
that it compiles indenendently, even if it is reincluded transitively later.
... Two controls were associated with the same path,
"/FileFormats/FFmpegMaxPredOrder"
But where the paths are read in ExportFFmpeg.cpp, that was read in one place,
and in another, "/FileFormats/FFmpegMaxPartOrder" was read, and that path was
not written anywhere.
The intention was surely that the other spin control should have used that path.
... except Audacity.h
This forces us to make each header contain all forward declarations or nested
headers that it requires, rather than depend on context.
... Remove all uses of the three-valued Cmp comparison member function, which
returns 0 for equality, except in one place. Use operators == and != instead.
(C++20's spaceship operator hasn't landed here yet!)
... Replacing:
Insert => insert
RemoveAt => erase
Remove => erase
IsSameAs => operator == or operator !=
(but only when second argument was true or default)
... instead use the utility make_iterator_range and its index() or contains()
method. This generic utility works with any container defining begin() and
end().
This further lessens dependency on wxWidgets container idioms.
... which will make it easier to change the types of those containers to
std::vectors of other string-like classes
for wxString,
IsEmpty => empty
Clear => clear
Alloc => reserve
for wxArrayString,
Count => size
GetCount => size
IsEmpty => empty
Add => push_back
Clear => clear
Empty => clear
Sort => std::sort (only with default comparator)
SetCount => resize
Last => back
Item => operator []
Alloc => reserve
... and similar wx "variadics," which all treat wxString smartly enough that
you don't need this.
Don't need c_str either to convert wxString to const wxChar * because
wxString has a conversion operator that does the same.
... Strong, meaning that the file at the specified path is created or modified
only if all write operations complete without exceptions, barring one very
unlikely possibility that a final file rename fails, but even in that case the
output is successfully written to some path.
This commit does not add throws, but changes the type thrown to a subclass of
AudacityException, so that GuardedCall will cause the user to see an error
dialog in all cases.
Duplicated logic for making temporary files and backups is now all in one
place, the class XMLWriter.
There may be more new GuardedCalls than necessary -- the catch-all for the
event loop, AudacityApp::OnExceptionInMainLoop, might be trusted instead in
some cases -- but they are sufficient.
