Outdated egg!

This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.

If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

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 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.
