The single use from friended class is in public interface. Removal of
friend designators allows Clang to pinpoint few additional unused
private fields.
Use the exact formatting suggested in COPYING file.
This change is basically a pretext to trigger a new clean build in
order to check if Coverity is capable of accepting new builds for
analysis finally.
Latest change from upstream made removed last usage of these functions.
Only ifdef-out them, in case future versions in upstream will use these
functions again.
This is old, and disabled by default in new MSVC compilers.
It was purely infomational warning:
"object name was truncated to 'number' characters in the debug
information"
Regardless, even if we'll decide to silence it again for any reason,
then it should be configured in VS project and not using ifdefed
pragma in the code.
Warning C4290 informs users, that MSVC ignores throw specification. This
is very good warning, because 'throw' specifications were faulty design
and got deprecated in C++11 and REMOVED from the language in C++20.
Throw specifications were replaced by much better 'noexcept' keyword,
which allows for compile-time checks, unlike 'throw', which might
silently inject exception 'std::unexpected'.
Static analyzer indicates that in this context `rem` can be NULL,
therefore should not be passed to strchr, but in this context `rem`
cannot be NULL becasuse `args` is not NULL (even after StripSpaces).
Previous implementation avoided invocation of 'pause' in many edge
cases, e.g.: when pause should be invoked between summary lines.
Avoid displaying '.' and '..' in root directory of mounted drive (just
like other dir implementations do).
Use C++11 for-each loop for iterating over directory entries.
Split code inside the loop by option, resulting in more readable
implementation.
Use "%*s" to inject empty whitespace of calculated size instead of
outputting spaces in a loop.
Leave some TODO notes describing further improvements.
This is in line with any other implementation of 'dir' command. It's
also very useful for identifying e.g. which floppy is currently mounted.
MS-DOS and cmd.exe display Volume Serial Number, but it emulating it in
DOSBox doesn't seem to be very useful.
There's no point in hardcoding these values - they can be different to
every user (it depends on hardware, OS, SDL version, etc).
Also, future versions of SDL might introduce more renderers, so this way
the code is more future-proof.
Otherwise users might easily miss, that this option is supposed to work
only for 'texture' output.
Also, do slight adjustments to formatting in generated .conf file.
With SDL2 in place, the silent dependency on libpng12 on Ubuntu 16.04 is
now gone. Unfortunately, development packages for libpng16 are named
differently for Ubuntu 16.04 and 18.04, so we can't add new package to
the global list.
Initial testing indicates, that problem described in this section in
README file might be fixed with SDL 2.0, but it is not fully confirmed
that it's fixed yet.
