From 5b8340563c271fb684a88c6e5bb6dd3bfb629058 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Dan=20Vr=C3=A1til?= Date: Wed, 6 Jun 2012 15:27:19 +0200 Subject: Mail formatter rewrite All mail-parsing and formatting code has been moved to em-format. Parsing is handeled by EMailParser class, formatting by EMailFormatter. Both classes have registry which hold extensions - simple classes that do actual parsing and formatting. Each supported mime-type has it's own parser and formatter extension class. --- em-format/e-mail-parser-inlinepgp-encrypted.c | 205 ++++++++++++++++++++++++++ 1 file changed, 205 insertions(+) create mode 100644 em-format/e-mail-parser-inlinepgp-encrypted.c (limited to 'em-format/e-mail-parser-inlinepgp-encrypted.c') diff --git a/em-format/e-mail-parser-inlinepgp-encrypted.c b/em-format/e-mail-parser-inlinepgp-encrypted.c new file mode 100644 index 0000000000..5395b7be7e --- /dev/null +++ b/em-format/e-mail-parser-inlinepgp-encrypted.c @@ -0,0 +1,205 @@ +/* + * e-mail-parser-inlinepgp-encrypted.c + * + * 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.
