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. --- widgets/table/e-cell-text.c | 2811 ------------------------------------------- 1 file changed, 2811 deletions(-) delete mode 100644 widgets/table/e-cell-text.c (limited to 'widgets/table/e-cell-text.c') diff --git a/widgets/table/e-cell-text.c b/widgets/table/e-cell-text.c deleted file mode 100644 index 6ad47b4c50..0000000000 --- a/widgets/table/e-cell-text.c +++ /dev/null @@ -1,2811 +0,0 @@ -/* - * This program is free software; you can redistribute it and/or - * modify it under the terms of the GNU Lesser General Public - * License as published by the Free Software Foundation; either - * version 2 of the License, or (at your option) version 3. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
