This package contains bindings to the SDL 2 library, in both high- and low-level forms:
The SDL
namespace contains high-level bindings, where enumerations are split
into sum types, and we perform automatic error-checking.
The SDL.Raw
namespace contains an almost 1-1 translation of the C API into
Haskell FFI calls. As such, this does not contain sum types nor error
checking. Thus this namespace is suitable for building your own abstraction
over SDL, but is not recommended for day-to-day programming.
Read SDL
for a getting started guide.
Changes
2.4.1.0
-
More SDL functions no longer allocate. See https://github.com/haskell-game/sdl2/pull/179 and https://github.com/haskell-game/sdl2/issues/178. Thanks to @chrisdone for this work.
-
Fixed an off-by-one bug in
SDL.Input.Mouse.getMouseButtons
. See https://github.com/haskell-game/sdl2/pull/177 for more information. Thanks to @Linearity for identifying and fixing this bug.
2.4.0.1
- Raise upper bounds for
exceptions
to <0.11
2.4.0
getRelativeMouseLocation
now returnsVector
instead ofPoint
.getModalMouseLocation
returns either aVector
or aPoint
, wrapped in (new)ModalLocation
.WindowSizeChangedEventData
includes the new window size.- Added an invalid state to the
ControllerButtonState
enum, and switched to a more reliable state detection method. - Raise upper bounds for
exceptions
to <0.10
2.3.0
- Windows builds now use
-D_SDL_main_h
. See https://github.com/haskell-game/sdl2/issues/139 for more discussion. - Some basic support for game controller events have been added. See
SDL.Input.GameController
and changes toControllerDeviceEventData
. - Support for event watching:
addEventWatch
anddelEventWatch
. - High-level bindings now distinguish between finger down / motion / up.
See
SDL.Event.TouchFingerEvent
andSDL.Event.TouchFingerMotionEvent
. - Several event payloads now have their
Window
fields modified to useMaybe Window
, substitutingNothing
for null pointers. - High-level structure for controller button state:
ControllerButtonState
. - High-level structure for controller buttons:
ControllerButton
. - High-level structure for controller connection:
ControllerDeviceConnection
. - High-level structure for joystick device connection:
JoyDeviceConnection
. - High-level structure for joystick button state:
JoyButtonState
. - Support for user defined events:
registerEvent
,pushRegisteredEvent
, andgetRegisteredEvent
. - Initial window visibility can be specified in
WindowConfig
forcreateWindow
function. WarpMouseOrigin
is now fully exported and can warp to global coordinates.- It’s possible to retrieve palette information with
paletteNColors
,paletteColors
andpalletColor
.

inSDL.Video.Renderer
setRelativeMouseMode
inSDL.Input.Mouse
getRelativeMouseMode
inSDL.Input.Mouse
getMouseLocation
inSDL.Input.Mouse

transitions not working properly between fullscreen and windowed modes.
2.1.3.1
- Raise upper bounds for
vector
to <0.13
2.1.3
- Cabal flag
no-linear
removes dependency onlinear
(and thus, transiently,lens
). SeeSDL.Vect
for details. - Remove ‘lens’ dependency from all examples.
- Add Cabal flag
opengl-example
to separate that target fromexamples
, because it is now the only example with an extra dependency (OpenGL). - Make
hlint
happy with examples. - Add
updateTexture
wrapper for nativeSDL_UpdateTexture
. - Expose
glGetDrawableSize
(can differ from window size in some environments). - Correct
hintToString
output to match SDL hint tokens, rather than the names of the CPP macros defining them. - Removed
ghc-options: -Wall
until we drop support for GHC 7.8. (>1300 warnings!) - Various documentation updates.
2.1.2.1
- Raise upper bounds for
lens
to <4.15 (affects examples only)
2.1.2
- Revise some documentation examples to be more idomatic
- Update
.gitignore
to coverstack
and other tools - Raise upper bounds for
transformers
to <0.6 - Lower required SDL2 version to 2.0.2.
- Fix decoding of
TextEditingEvent
where the Raw bindings failed to stop reading character data past the null terminator.
2.1.1
SDL.Input.Mouse
new has a new API for fetching the location of the mouse. This API gives you greater control over finding the mouse position with respect to the various “modes” a mouse can be in. The old API still exists, but will be removed at some point in the future.SDL.Raw
now has a binding toSDL_free
.
2.1.0
- Introduce
initializeAll
and deprecateInitEverything
. To fix this deprecation warning, changeinitialize [InitEverything]
toinitializeAll
. surfaceColorKey
,surfaceFillRect
andsurfaceFillRects
now all operate on on RGBAV4 Word8
values. They all implicitly map and unmap (usingSDL_MapRGBA
andSDL_GetRGBA
respectively).SDL.mapRGB
is now deprecated, as this conversion is always done for you. If you still need this routine, useSDL.Raw.mapRGB
.- Fix a runtime crash when reading the current BlendMode of a texture. Thanks to @seppeljordan for discovering and fixing this bug.
2.0.0
- Introduce a set of comprehensive high-level bindings to SDL. These bindings
should allow users to work with SDL while writing idiomatic Haskell code. They
take care of pointer manipulation, and wrap up values in much more “natural”
data types. The high-level bindings live in the
SDL
namespace, and have been extensively documented. - Raw bindings have been moved from
Graphics.UI.SDL
toSDL.Raw
.
