Bug 4229 – emerge --pretend in a tree listing format

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Aniruddha Shankar 2002-06-27 07:00:38 UTC]

Emerge --pretend should list packages in a tree format so that we can understand which 
packages depend on which ones. 

Example

 foo  [ U]
   \---- > bar [N]
   \-----> bork [U]
                 \--- >bleh [U]
  bleep [N]
    \-----> bloop [U]

Dont know if this could be a nice feature ..

[Comment 2 Masatomo Nakano (RETIRED) 2003-08-04 10:44:30 UTC]

I made a patch two weeks ago for this.
But I'm not sure it's useful..

example.
# emerge -pve lv

These are the packages that I would merge, in order:

Calculating dependencies ...done!

[Comment 4 SpanKY 2003-08-04 15:32:48 UTC]

well the idea is this:  
  
emerge bitchx -p  
-[ebuild  N    ] sys-libs/glibc-2.2.5-r8 
---[ebuild  N    ] app-text/ghostscript-7.05.6-r3 
--[ebuild  N    ] net-print/cups-1.1.19-r1 
--[ebuild  N    ] media-libs/fontconfig-2.2.1 
--[ebuild  N    ] app-arch/cabextract-0.6 
-[ebuild  N    ] x11-base/xfree-4.3.0-r3 
-[ebuild  N    ] sys-libs/ncurses-5.3-r3 
-[ebuild  N    ] dev-libs/openssl-0.9.6j 
[ebuild  N    ] net-irc/bitchx-1.0.19-r5 
 
that way you can say 'ok, so bitchx will pull in ssl, curses, glibc, xfree ... xfree will 
pull in cabextract, fontconfig, cups ... cups will pull in ghostscript' 
 
you're not sitting there going 'ok, wth is pullin in ghostscript and how can i kill 
them' 

[Comment 5 Masatomo Nakano (RETIRED) 2003-08-04 15:41:56 UTC]

My patch just reverses the list. Which is good? 
I like my style. :)

[Comment 6 Masatomo Nakano (RETIRED) 2003-08-04 15:44:05 UTC]

And do we need new option for this(example --depth)?
Or it works when you append --verbose.

[Comment 7 SpanKY 2003-08-04 16:25:13 UTC]

reversing it is fine so long as it does a correct tree ;) 
 
i'd say just piggyback 'verbose' 

[Comment 8 Nicholas Jones (RETIRED) 2003-08-06 01:24:35 UTC]

Use --tree

Buy change the format using whitespace instead of '-' and
only vary the positioning.

[XXXXXX FLAGS] net-irc/bitchx
[XXXXXX FLAGS]   dev-libs/openssl


Better tree-like ordering would be nice, but can be worked out later.

patch for portage.py/emerge

I improved this patch when it's specified --deep option
I think this patch is very usuful for beginer and expert of portage

Example ("nomerge" lines are darkblue.)
# emerge -UDp --tree world
>>> --upgradeonly implies --update... adding --update to options.

These are the packages that I would merge, in order:

Calculating world dependencies ...done!
*** Portage will stop merging at this point and reload itself,
    recalculate dependencies, and complete the merge.

I second that request, this make emerge -u --deep world make sense :)

[Comment 14 Nicholas Jones (RETIRED) 2003-10-26 22:56:44 UTC]

Nice. You even caught --tree --columns. :)

Looking it over now.

[Comment 15 Nicholas Jones (RETIRED) 2003-11-08 11:13:31 UTC]

Included for next release.
