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.

forcreateWindow
function. WarpMouseOrigin
is now fully exported and can warp to global coordinates.- It’s possible to retrieve palette information with
paletteNColors
,paletteColors
andpalletColor
.

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

glGetDrawableSize
(can differ from window size in some environments). - Correct

.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
.
