🐛 Bug Fixes

Fix: Treat gunichar as string type instead of number (#265)

This release addresses a critical type mismatch issue where gunichar was incorrectly typed as number instead of string in GJS TypeScript definitions.

What was fixed:

• Core type resolution: Moved gunichar from number type resolution to string type resolution in type utilities
• Array handling: Updated primitive array type resolution to properly handle gunichar arrays as string arrays
• Type consistency: Ensures gunichar parameters and return values are correctly typed as string throughout generated TypeScript definitions

Why this matters: In GJS, gunichar represents Unicode characters as strings, not numeric code points. This was causing type mismatches in functions like Gtk.TextCharPredicate where parameters expected strings but were typed as numbers.

Testing: Added a new comprehensive test example (examples/glib-2-types/) that demonstrates proper type handling for various GLib string and Unicode functions, including UCS-4 conversion functions and Unicode character property functions.

Fix: Make bind_property_full Closure parameters nullable (#266)

Fixed incorrect TypeScript type definitions for GObject's bind_property_full method where transformation parameters were not properly nullable.

What was fixed:

• Parameter nullability: transform_to and transform_from parameters in bind_property_full are now correctly typed as Closure | null
• Documentation alignment: Types now match the GObject documentation which clearly states these parameters can be "or %NULL to use the default"
• Upstream bug workaround: Added specific injection to handle missing nullable="1" attributes in the GObject-2.0.gir file

Before:

bind_property_full(
    // ...
    transform_to: Closure,      // ❌ Not nullable
    transform_from: Closure,    // ❌ Not nullable
): Binding;

After:

bind_property_full(
    // ...
    transform_to: Closure | null,   // ✅ Now nullable
    transform_from: Closure | null, // ✅ Now nullable
): Binding;

Why this matters: This fix allows developers to pass null for transformation functions when using default property binding behavior, which is the most common use case. Previously, TypeScript would incorrectly flag this as a type error.
