Gloss hides the pain of drawing simple vector graphics behind a nice data type and a few display functions.
- Home page and bug tracker are on a separate site.
Getting something on the screen is as easy as:
import Graphics.Gloss
main = display (InWindow "Nice Window" (200, 200) (10, 10)) white (Circle 80)
Explore and run the example projects using stack:
$ stack setup
$ stack build
$ stack exec gloss-boids
Once the window is open you can use the following:
-
Quit
- esc-key
-
Move Viewport
- arrow keys
- left-click drag
-
Zoom Viewport
- page up/down-keys
- control-left-click drag
- right-click drag
- mouse wheel
-
Rotate Viewport
- home/end-keys
- alt-left-click drag
-
Reset Viewport
- 'r'-key
- Animations and simulations can be constructed similarly using the 'animate' and 'simulate' functions
- Games with user input can be constructed with the 'play' function.
- See the gloss-examples package for more.
As Gloss is now fairly stable, I typically make releases only when there is a new GHC version. If you have added a new feature or fixed a bug, and want your pull request merged sooner than that, then send email to benl AT ouroborus.net. I don't pay attention to github notifications, but am happy to receive emails from people. If you have changed any internal functionality then please test that all the gloss-examples still work before submitting your pull request.
If you just want to bump a dependency version then get a Hackage trustee to edit the package information directly on Hackage. You don't need to raise a pull request here.
