Is it possible to collapse quoted text?
I know I can collapse whole messages and they are shortcuts to move from message to message, but sometimes I would prefer to be able to collapse the quoted text.
Is there some way to do this? I've spent quite a bit of time reading the (great, thorough) docs and haven't found anything.
Assuming there isn't I'm up for having a go at doing this, so any pointers as to where in the code would be appropriate to start would be appreciated.
This is not possible with the current implementation unfortunately.
I think one way to start making this possible is to
somehow parse a "body string" of a mail into a tree (of strings)
and then use a derived widget-tree instead of the TextlinesList
in alot.widgets.thread.MessageTree
You might want to play around a bit with the urwidtrees library
I wrote (which is in alot/foreign/urwidtrees/, including example code).
As the MessageTree class already derives from CollapsibleTree,
it can already collapse subtrees. So having the body text
not as a list of lines but as a tree (alot.foreignurwidtrees.tree.Tree that is),
means you can use the collapse/expand methods on it
(and on the NestedTree accessible via ui.current_buffer.self._nested_tree in thread mode).
Then, one would only need commands to expand/collapse the subtree under the focus
(use ThreadBuffer.get_focus() and hand it to NestedTree.expand...)
So, a good start would be to parse the return value of accumolate_body (or similar),
into a urwidtrees.tree.Tree of alot.widgets.thread.FocusableText widgets.
In the long run, It'd be great not to hardcode this but have some sort of expandable parser that translates a email object into a Tree. This could in theory deal with sub-parts in the messages MIME-tree individually (see the partial solutions in the "mimeparsing" branches). For instance, it could call external text-renderer for attachments, or even for text-parts, pipe them through some external tool or hook that turns it into a text enriched with ascii escape codes for colours etc (see issues #272, #612).
I hope this helps more than it is confusing.. Have fun, /p
+1 for this feature. Reading long threads is extremly confusing with a lot of replies that all quote the past mails.
