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. --- composer/e-msg-composer.c | 63 +- data/webview.css | 2 +- em-format/Makefile.am | 105 +-
