Targeted release: Fedora 25
Last updated: 2016-04-29
Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Let's take a look on Python code import gi; gi.require_version("Tracker", "1.0"); from gi.repository import Tracker. To run it requires Tracker-1.0.typelib, which currently is in tracker package. With this change to package will be automatically added "Requires: typelib(Tracker-1.0)".

Libraries themselves requires another typelib packages. Let's take Webkit2-4.0.typelib, it requires itself:

some typelibs: typelib(Gtk-3.0) typelib(Pango-1.0) typelib(GObject-2.0) typelib(xlib-2.0) typelib(cairo-1.0) typelib(JavaScriptCore-4.0) typelib(Gdk-3.0) typelib(Gio-2.0) typelib(Atk-1.0) typelib(GdkPixbuf-2.0) typelib(Soup-2.4) typelib(GModule-2.0) typelib(GLib-2.0)
some shared libraries: libwebkit2gtk-4.0.so.37 libjavascriptcoregtk-4.0.so.18

All of them will be added automatically as requirements.

Benefit to Fedora

No need to specify Requires for packages which are using GI
Easy to install any GI libs

Scope

Proposal owners:

1. Write tool for introspection of GI typelibs

2. Write RPM dependency-generator
