From f0d3f3afdfa314e1e8cd7d8da790878008a46aad Mon Sep 17 00:00:00 2001 From: Matthew Barnes Date: Wed, 24 Jun 2009 12:59:33 -0400 Subject: Radically reorganize source code. - Collect all shell modules into a new top-level 'modules' directory: $(top_srcdir)/modules/addressbook $(top_srcdir)/modules/calendar $(top_srcdir)/modules/mail Nothing is allowed to link to these, not plugins nor other modules. THIS SOLVES BUG #571275 AND OPENS THE DOOR TO PORTING TO MAC OS X. - Mimic the libevolution-mail-shared library from master (except drop the "shared" suffix) and have libevolution-mail-importers and all mail-related plugins link to it. - Discard the a11y subdirectories and have the files live alongside their counterpart widgets. --- widgets/text/Makefile.am | 8 +- widgets/text/a11y/gal-a11y-e-text-factory.c | 101 --- widgets/text/a11y/gal-a11y-e-text-factory.h | 50 -- widgets/text/a11y/gal-a11y-e-text.c | 1134 --------------------------- widgets/text/a11y/gal-a11y-e-text.h | 57 -- widgets/text/e-text.c | 2 +- widgets/text/gal-a11y-e-text-factory.c | 101 +++ widgets/text/gal-a11y-e-text-factory.h | 50 ++ widgets/text/gal-a11y-e-text.c | 1134 +++++++++++++++++++++++++++ widgets/text/gal-a11y-e-text.h | 57 ++ 10 files changed, 1347 insertions(+), 1347 deletions(-) delete mode 100644 widgets/text/a11y/gal-a11y-e-text-factory.c delete mode 100644 widgets/text/a11y/gal-a11y-e-text-factory.h delete mode 100644 widgets/text/a11y/gal-a11y-e-text.c delete mode 100644 widgets/text/a11y/gal-a11y-e-text.h create mode 100644 widgets/text/gal-a11y-e-text-factory.c create mode 100644 widgets/text/gal-a11y-e-text-factory.h create mode 100644 widgets/text/gal-a11y-e-text.c create mode 100644 widgets/text/gal-a11y-e-text.h (limited to 'widgets/text') diff --git a/widgets/text/Makefile.am b/widgets/text/Makefile.am index e035d8714d..70adbfec39 100644 --- a/widgets/text/Makefile.am +++ b/widgets/text/Makefile.am @@ -14,8 +14,8 @@ libetext_la_SOURCES = \ e-text.c \ e-reflow.c \ e-reflow-model.c \ - a11y/gal-a11y-e-text-factory.c \ - a11y/gal-a11y-e-text.c + gal-a11y-e-text-factory.c \ + gal-a11y-e-text.c libetextincludedir = $(privincludedir)/text @@ -25,8 +25,8 @@ libetextinclude_HEADERS = \ e-text.h \ e-reflow.h \ e-reflow-model.h \ - a11y/gal-a11y-e-text-factory.h \ - a11y/gal-a11y-e-text.h + gal-a11y-e-text-factory.h \ + gal-a11y-e-text.h libetext_la_LDFLAGS = $(NO_UNDEFINED) diff --git a/widgets/text/a11y/gal-a11y-e-text-factory.c b/widgets/text/a11y/gal-a11y-e-text-factory.c deleted file mode 100644 index 2df9241014..0000000000 --- a/widgets/text/a11y/gal-a11y-e-text-factory.c +++ /dev/null @@ -1,101 +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.
