AUTOTYPE performs scripted keyboard entry into the running
DOS program.
It can be used to reliably skip intros, answer Q&A style questions
that some games ask on startup, or conduct a simple demo.
It allows for delaying input by any number of fractional seconds,
as well defining the pacing between keystrokes. It uses the
comma character "," to insert additional delays similar to modern
phone numbers.
It uses key_* names as defined by the mapper to avoid using SDL
scancodes[1], which are unstable across platforms. This approach
also allows the triggering of custom key bindings the use has
defined.
[1] https://wiki.libsdl.org/SDL_GetScancodeName
"Warning: The returned name is by design not stable across
platforms, e.g. the name for SDL_SCANCODE_LGUI is "Left GUI" under
Linux but "Left Windows" under Microsoft Windows, and some
scancodes like SDL_SCANCODE_NONUSBACKSLASH don't have any name at
all. There are even scancodes that share names, e.g.
SDL_SCANCODE_RETURN and SDL_SCANCODE_RETURN2 (both called
"Return"). This function is therefore unsuitable for creating a
stable cross-platform two-way mapping between strings and
scancodes."
The new output type `texturepp' was added, which implements
pixel-perfect scaling using SDL's hardware-accelerated texture output.
In pixel-pefect mode, each original pixel is displayed as a rectangle m
by n pixels, so that m:n yields a reasonably good approximation of the
pixel aspect ratio (PAR) of the emulated graphical mode while using as
much screen space as possible. The balance between the precision of
aspect ratio and the utilisation of screen space is specified as the
`parweight' parameter to pp_getscale() and is currently hard-coded in
sdlmain.cpp.
This implementation emulatates pixel-perfect mode as a special case of
nearest-neighbor interpolation when the horisontal and vertical scaling
factors are integers.
Judging by the usage, this header belongs in there instead of being
limited to dos module only. This change makes it easier to reuse code
for new features related to drives mounting/unmounting.
Also, remove all traces of these interfaces from user manual (README
file) and man page (docs/dosbox.1).
MCI (Media Control Interface) was a primary Windows interface. Code
comments and documentation claimed, that it's only for "NT, 2000, XP"
but the code was enabled for Windows 2000 or later (version > 4.0).
DX (Digital audio eXtraction (?)) could be forced on any Windows with
autodetection working only on Vista and Windows 7 (code was disabled for
Windows 8 or later - probably unintentionally).
DIO used DeviceIoControl interface and Windows-specific ioctl calls.
All 3 interfaces depend on SDL and SDL_cdrom functionality to work.
SDL_cdrom 1.2 implementation uses MCI on Windows to provide the same
functionality.
ASPI was supported by Microsoft only for Windows 95, 98 and, ME.
Adaptec supported this interface going forward for Windows NT, 2000,
and XP (32-bit only).
Name 'visualc_net' invokes old names for Visual Studio
(Visual Studio .NET 2002 or 2003), which has no relation to content of
this subdirectory.
Also, by renaming this directory we mitigate chance, that during
merge-in from svn/trunk git will automatically inject some values from
from upstream, incompatible version of solution files. By sheer
luck this might happen without causing a conflict. Never happened so
far, but there's no point in risking it.
