From d09d8de870b6697c8a8b262e7e077b871a69b315 Mon Sep 17 00:00:00 2001 From: Matthew Barnes Date: Mon, 10 Dec 2012 08:09:59 -0500 Subject: Consolidate base utility libraries into libeutil. Evolution consists of entirely too many small utility libraries, which increases linking and loading time, places a burden on higher layers of the application (e.g. modules) which has to remember to link to all the small in-tree utility libraries, and makes it difficult to generate API documentation for these utility libraries in one Gtk-Doc module. Merge the following utility libraries under the umbrella of libeutil, and enforce a single-include policy on libeutil so we can reorganize the files as desired without disrupting its pseudo-public API. libemail-utils/libemail-utils.la libevolution-utils/libevolution-utils.la filter/libfilter.la widgets/e-timezone-dialog/libetimezonedialog.la widgets/menus/libmenus.la widgets/misc/libemiscwidgets.la widgets/table/libetable.la widgets/text/libetext.la This also merges libedataserverui from the Evolution-Data-Server module, since Evolution is its only consumer nowadays, and I'd like to make some improvements to those APIs without concern for backward-compatibility. And finally, start a Gtk-Doc module for libeutil. It's going to be a project just getting all the symbols _listed_ much less _documented_. But the skeletal structure is in place and I'm off to a good start. --- Makefile.am | 7 +- a11y/Makefile.am | 23 - a11y/ea-factory.h | 114 - a11y/gal-a11y-factory.h | 85 - a11y/gal-a11y-util.c | 49 -
