Generate Haskell bindings for GObject Introspection capable libraries. This includes most notably
Gtk+, but many other libraries in the GObject ecosystem provide introspection data too.
Changes
0.26.6
Work around changing conventions about what the closure n annotation means: many annotations appear on the callback, pointing to the user_data argument, but sometimes it also appears on the user_data argument, pointing to the callback. See issue 407 for a place where this becomes a problem.
0.26.5
Add a reference to ?self argument in signals. See issue 408 for the motivation.
0.26.0
Support for ‘HasField’ methods, which allows the syntax ‘widget.show’ or ‘widget.add child’ for invoking methods using the new RecordDotSyntax in ghc 9.2.
And an implicit ‘?self’ parameter for callbacks, for accessing the calling object. See issue 346 where this is necessary in practice in gtk4 to use event controllers.
Add an ‘After’ attribute to connect to signals after the default handler on constructors/setters using attribute syntax, similar to On.
Remove the command line version of the bindings generator.
Remove support for non-IsLabel overloading.
Add resolveMethod for showing what an overloaded method resolves to: resolveMethod #show widget will output GI.Gtk.Objects.Widget.widgetShow.
0.24.5
Fix an accidental double free for GValues, see issue 320.
Accept docsections in gir files, although they are currently ignored. See issue 318.
0.24.4
Relax bound on ansi-terminal.
0.24.3
Provide type init functions for GParamSpec types. This solves a puzzling linker error saying that the “intern” symbol could not be resolved, see issue 297 and issue 298.
0.24.2
Support for allocating GArrays of known size structs in caller-allocates arguments.
0.24.1
Add support for delete-attr override, to remove attributes.
Allow (but ignore) destroyers in scope async callbacks.
0.24.0
Added support for non-GObject objects
0.23.2
Fix a possible segfault in functions that return an out pointer to a dynamically allocated array, but do not initialize the array if it has zero size. See #289 for an example.
0.23.1
Check whether symbols exist in the dynamic library before trying to generate bindings for them, in order to avoid linker errors.
0.23.0
gobjectType now does not require a proxy argument, it needs to be used with TypeApplications instead.
Annotated signals are supported: on widget (signal ::: "detail").
Safe coercions to parent types supported, with asA.
Support for GObject subclassing, and registering custom properties.
Use TypeApplications in AttrInfo implementation, and inherited methods implementation.
Add an allocating setting operator (:&=).
Support for exporting class structs.
IsGValue instances for GObjects and boxed objects.
0.22.6
Fix generated IsX typeclasses for non-GObject interfaces.
0.22.5
Add support for inheriting overloading info.
0.22.4
Do not generate bindings for struct/union fields pointing to private/class structs, which we do not bind.
0.22.3
Sometimes struct fields marked as not introspectable contain invalid introspection info. We are lenient in these cases with parsing errors, and simply ignore the fields.
0.21.5
Add support for callback-valued properties.
0.21.4
Try to guess signedness of enums and flags on the C side, fixes #184.
0.21.3
Do not add nodes in overrides if a node with the same name already exists, fixes #171.
0.21.2
Do not free Ptr Word8 types after performing the call to C,
since they only get passed along. Otherwise one could easily double free in functions such as GdkPixbuf.pixbufNewFromData.
Fix a leak on optional ScopeTypeAsync callbacks.
0.20.4
Improve marshaling of array arguments with no specified size. This improves the generated bindings for various functions, for instance GObject.signalEmitv.
Replace the enable-overloading flags with a explicit CPP check of the version of haskell-gi-overloading we are being compiled against, see issue 124 for the rationale.
0.20.3
Make the overloading code protected by a CPP conditional, depending on ENABLE_OVERLOADING being defined. See issue 107.
Wrap boxed structs/unions as transient ManagedPtrs in callbacks. This is needed to fix a number of issues, including issue 96 and issue 97.
0.20.2
Fixes for GHC 8.2.1.
0.20.1
gtk-doc parser and haddock generator: while by no means perfect,
now the autogenerated bindings come with some reasonable
autogenerated documentation.
Many bugfixes. A particularly important one is for
issue 82, which
made compilation of
gi-glib fail, for
the latest version of gobject-introspection.
