iota 0.4.0-alpha

iota

Input-output (audio, controls, etc) library for D. Intended as a D language native replacement for SDL, SFML, etc.

Current state

MacOSX is not yet supported due to lack of hardware. Please consider contributing to this project!

Wayland is not supported yet as XWayland provides sufficient compatibility.

Audio

Windows

Only WASAPI output is supported at the moment, but it seems to work correctly. Buffer overflow protection is done through spinning in a loop alongside with the wait. It's not nice, but works, and eliminates possible issues from inconsistent buffer sizes.

Deinitialization is automatic through destructors and bug free. Windows-specific error-codes are handled as should.

Linux

Error handling is quite preliminary with one having to rely on returned error codes. ALSA device names are now handled.

Audio is tested and confirmed working on 64 bit Raspberry Pi devices, which probably means all 64 bit ARM SoCs are supported under Linux.

NOTE: Due to the janky nature of ALSA, it'll be only be kept as a last-resort compatibility measure.

MIDI

Windows

Both input and output works, but might suffer from some caveat that stems from the Windows MIDI API. There's a chance that calling a MIDI system function within the MIDI input callback will cause a lockup.

Linux

Input tested, output also should work.

Note: Must be deinitialized manually.

Controls

Windows

Keyboard and mouse works without much issues while using the legacy API. A known bug is that it sometimes generates an additional empty event if the Alt key is pressed (because some people thought it's a good idea to dedicate a whole modifier key for the menubar), this can be mitigated by supplying the window a WindowCfgFlags.IgnoreMenuKey. Menubars are not implemented currently.

XInput is implemented and works.

Raw input

This library is (mostly) equipped to handle raw input data. There was a bug that made handle lookup not working, this is no longer the case.

I plan to make game controllers working via RawInput, but that will be a bit more work due to scarce documentation...

Linux

I/O without extensions now works, XInput2 support will be added once I find or someone provides me the API documentation. Quite hard to search, due to same name of what Microsoft has under Windows for Xbox gamepads.

Evdev

Libevdev support has added, but does not work currently, it hangs.

Windowing

Windows

Got most of the basic stuff working. Bug related to window styles fixed.

Fullscreen is working, video modes are untested as of now.

Linux

Linux is using X11 for its windowing and I/O.

OpenGL

It works for what I've tested it, Windows parts might have their own unique challenges later on.

Examples

See testsource/app.d for audio, inputtest/app.d for input and basic windowing, and miditest/app.d for MIDI.

To do list

• Add option for hiding mouse.
• Add Vulkan support.
• Add support for alternative runtimes/memory managers.
