More trees

More trees

[Lars Magne Ingebrigtsen]

I thought it might be neat to provide a different tree generation
function -- one that grows downwards with thread depth instead of
sideways.  Here's the original function:

{***}-(***)-[odd]-[Gun]
     |     \[Jan]
     |     \[odd]-[Eri]
     |     \(***)-[Eri]
     |           \[odd]-[Paa]
     \[Bjo]
     \[Gun]
     \[Gun]-[Jor]

And here's the new one:

{***}
  |--------------------------\-----\-----\
(***)                         [Bjo] [Gun] [Gun]
  |--\-----\-----\                          |
[odd] [Jan] [odd] (***)                   [Jor]
  |           |     |--\
[Gun]       [Eri] [Eri] [odd]
                          |
                        [Paa]

Uhm.  I thought the new function would produce taller outputs than the
old one...

As a comparison, here's the output from the summary buffer for the
same thread:

R  [  17: Gunnar Horrigmo     ] Re: Oslonetts sex-trauma
R      <  26: Gunnar Horrigmo     > 
R          [  19: Jorn Ommund Topnes  ] 
R      <  14: Bjorn Remseth       > 
Q      <   0:                     > 
R          [  40: oddms               ] 
R              [  13: Gunnar Horrigmo     ] 
R          [  12: Jan Ingvoldstad     ] 
R          [  10: oddms               ] 
R              [  21: Erik Naggum         ] 
Q          [   0:                     ] 
R              [  33: Erik Naggum         ] 
R              [  28: oddms               ] 
R                  [  14: Paal Thingbo        ] 

Well, the tree displays are more compact than the summary display --
but that's not really surprising since there's less information in the
tree displays...

 I've been using the gnus-fetch-old-headers functionality to
``replicate'' the trn trees look-and-feel.  replicate is used in the
``at least I can vaguely see how they are related now'' sense.  This
trn trees stuff looks very good to me.

 It took me a little time to read this as (I think) it's been time
reversed, ie shouldn't it be reflected in the vertical plane?

 If you read top-down left-right (we may want this configurable for
those reading/learning Chinese and the like) I would expect the tree
to grow from top to bottom -- this bit is OK.  As I read from left to
right, I would expect to find the eldest article on the left, the
newest on the right which would make the above tree look like: --
ahem, I was going to redraw but I relise my editing skills aren't up
to it!

 Anyway, perhaps the left-right == eldest-newest should be
configurable as well?

Cheers,

This version of the tree shows generations when read from the top and
down.  The other version shows (as you suggest) generations when read
from left to right.  Doing bottom-up and right-left versions would
simply entail reversing the buffer.  Sort of.
