* Teach EMailExtensionRegistry to find extensions.Matthew Barnes2013-02-011-41/+0
| | | | Restore this commit with a proper bug fix to follow.
* Revert "Teach EMailExtensionRegistry to find extensions."Milan Crha2013-01-291-0/+41
| | | | | | | | | | This reverts commit bf30024dd7973006bf99d0ae509a7f0022368a41, because it breaks EMailFormatter/Parser extensions, like the prefer-plain. The thing is that the internal formatters/parsers (also extensions) should be always added first, and only after then can be added extended extensions, which are used before those internal. This constraint was not satisfied with the reverted commit, the order of extension registration was unpredictable, depended on GType.
* Teach EMailExtensionRegistry to find extensions.Matthew Barnes2012-12-081-41/+0
| | | | | | | | | | | | | | | | | | | | | Now we have the following extension points in the GType hierarchy: E_TYPE_MAIL_FORMATTER_EXTENSION E_TYPE_MAIL_FORMATTER_PRINT_EXTENSION E_TYPE_MAIL_FORMATTER_QUOTE_EXTENSION E_TYPE_MAIL_PARSER_EXTENSION A registry just needs to be given one of these extension points, and it can use g_type_children() to find and load all registered extensions. This eliminates e-mail-format-extensions.[ch] as well as the dynamic loaders I added a few commits back. Dynamically loaded extensions are now easier to register, at the cost of internal extensions being a tad more cumbersome to register. Fair tradeoff, imo. This also makes e_mail_extension_registry_add_extension() a private function used only by e_mail_formatter_extension_registry_load() and e_mail_parser_extension_registry_load().
* Convert EMailParserExtension to an abstract class.Matthew Barnes2012-12-081-19/+9
| | | | | | | | | With the previous changes, all parser extensions derive from GObjectClass and implement the EMailParserExtensionInterface. Simplify things further by making EMailParserExtension an abstract base class so parser extensions are now just direct subclasses and need not bother with implementing GObject interfaces.
* Remove EMailExtension.Matthew Barnes2012-12-081-30/+40
| | | | | | | | | | | | EMailExtension is now too trivial to keep as a standalone interface. Add a 'mime_types' string array to the EMailFormatterExtension and EMailFormatterParser interface structs. Alter e_mail_extension_registry_add_extension() to take a 'mime_types' string array and the GType of an extension to instantiate, rather than the extension instance directly. e_mail_extension_registry_remove_extension() is no longer needed.
* EMailExtension: Replace mime_types() method with a string array.Matthew Barnes2012-12-081-7/+1
| | | | | | | | | | | In all implementations for EMailExtension, the MIME type list is a static string array -- with the single exception of the text-highlight module, where the MIME type list is dynamically assembled once. Replace the mime_types() method with a "mime_types" string array in the EMailExtensionInterface struct. Then the list of MIME types supported by the class implementing the EMailExtensionInterface can be obtained without requiring an instance of the class.
* EMailParserExtension: Collect EMailParts in a GQueue.Matthew Barnes2012-12-081-13/+13
| | | | | | | | | | | | | | | Collect EMailParts in a GQueue provided to the EMailParserExtension, and change the return type of parse() to gboolean to indicate whether the given CamelMimePart was handled (even if no parts were added to the output GQueue). This avoids the awkward corner case of a parser extension returning a linked list node with a NULL data member to indicate the CamelMimePart was handled but no EMailParts produced, and then having to watch out for that NULL data member corner case throughout the application. Also, remove the GCancellable parameter from e_mail_parser_error() and e_mail_parser_wrap_as_attachment() since neither function blocks.

* Highlighting of text parts and source codesDan Vrátil2012-07-251-0/+159
This adds 'Format as' submenu to the preview pane context menu. The submenu is available only for text/plain parts or parts with a source code (we support about 40 various types). Using the 'highlight' utility, the formatter processes the part and highlights the source code it contains. (discussion in bug #680026)
