This reverts commit 7050a12868, which broke opening of IMAP message.
It's also the correct solution for the initial issue, because
the message_uid can contain letters which should be encoded in the URI.
If the highlight program cannot be found width AC_PATH_PROGS,
configure will abort with an error message.
You can either
a) install highlight
b) specify the patch with HIGHLIGHT=/path/to/highlight
c) pass --disable-text-highlight to configure to exclude the module
This also makes text-highlight module to fallback to text/plain
formatter when highlight program would crash or fail to ensure
the content is delivered to user.
This way the view corresponds to the original part properties,
not those stripped by the inline filter. Also initialize
EMailInlineFilter::filename on creation of the structure, thus
the value is actually used on the subparts, if needed.
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)
The new formatter was ignoring selected headers, always displaying
only From, To, Subject and Date (default headers).
Handling of the currently displayed headers has been moved to
EMailConfigFormatHTML extension, because it is related to
configuration of EMailFormatter, rather then EMailReader.
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.
