Allegro 5.0 bindings for Chicken.

Author

Dan Leslie (dan@ironoxide.ca)

Subpages

The allegro docs are divided up into pages by category.

Disclaimer

Due to personal time constraints I have not fully tested these bindings, yet. If you discover any bugs, or even if you believe that some bindings could have a better implementation then please contact me with details.

And yes, the Egg does take a bloody long time to compile.

Help!

I have limited time these days. If you could undertake any of the following it would be greatly appreciated:

1. Submit issues you discover to the GitHub issue tracker 2. Submit feature requests to the GitHub issue tracker 3. Correct any errors you discover in this documentation page 4. Add documentation where it is lacking 5. Send me an email if you find this egg useful!

Repository

The main repository can be found on GitHub.

Supported Versions

Allegro versions 5.0.x up to 5.0.6 are supported. All 5.0.x versions should work, but features added post-5.0.6 will not be available.

Future version support will likely be added in the future. Patches are welcome!

Examples

A growing number of examples can be found on [https://github.com/dleslie/allegro-examples|GitHub].

Please contribute!

Windows Extras

Since building all your packages on windows is a bit of a pain in the ass I've written the Egg with the assumption that you're using the pre-built Allegro libraries. The only extra step you'll need to do, after installing the prebuilt Allegro bins to your MingW32 directory should be:

# cd /MingW/lib
# cp liballegro-INSTALLED_VERSION-monolith-md.a liballegro.a

Assuming, of course, that you've installed MingW32 to C:\Mingw

Naming Key

In general, the naming is fairly indicative of the function's behaviour.

The gist is something like this:

make-type
Constructs a type (Not always available)
make-type*
Constructs a type, returning a value which must be manually destructed
free-type!
Manually destructs a type (Not available for internally managed types)
type-noun
Accessor for value "noun" on a specific type
type-noun-set!
Mutator for value "noun" on a specific type
type-verb
Method which requires a specific type to operate
type-verb!
Method which modifies an object of a specific type
verbage
Function which operates on the global state
verbage*
Function which operates on the global state, but also returns a value which must be manually destructed

If a function begins with a type name then you can be assured that the first parameter will be an object of that specific type.
