Thanks. Will do.

Good idea... it shouldn't be a big deal to do that... I was just trying 
to keep the patch nice and simple.

It repeats the USE flags for each package, but ONLY the use flags that 
apply to that package. Personally, I think this is a more desirable 
behavior, because of when you do something like 'emerge world', then 
you'll have this really BIG list of stuff, and lots of repeating USE 
flags. However, it puts a empty line between each package, so that each 
list of USE flags is shown nicely for each package.. like this:

[stuff here] package useflag useflag2
* useflag - does something
* useflag2 - does something else

[stuff here] package useflag3 useflag
* useflag3 - does yet another thing
* useflag - does something

And so on... for the entire list. Currently, it searches global flags 
first, then falls back to local flags... but you're right -- its a 
better idea to search locals first, then globals. I don't really think 
its necessary though to note that its a local flag or a global flag... 
its not like it matters too much when you're trying to decide whether 
you want to set it or not. You just want to know what the package wants 
to use it for. I spose it could do something like * [local] useflag - 
description, and * [global] useflag - description...

May be a duplicate of bug #84884 though, which has, among other
things, a patch for emerge (2.0.51.x too) similar in purpose to
what you are proposing (although there are some cosmetic
differences, like option name or the info being summarized at the
end instead of being displayed per package):
https://bugs.gentoo.org/show_bug.cgi?id=84884

Btw, there was not much feedback on that one... would someone be
interested if i port it to CVS HEAD? As far as i remember, it
should be pretty easy, although the emerge patch has to be
rewritten.

The one that you mentioned seems to be a little bit more involved than 
my patch. Which, if thats ok with you, then its ok with me :) His is a 
full class that can be used to get various things... while mine just 
goes out there, opens the file, then displays the results... the class 
idea is more efficient it would seem (only opens file once).

Although, instead of using his proposed --use-local-desc, and etc... it 
could be something like --vv (a shorter "long" option), or -vv (but 
wouldn't that mean rewriting some of the code to handle options?), like 
mentioned above.

My guess on the lack of feekback on the bug is that a feature like this 
wouldn't be as useful to someone who isn't new to gentoo, and in fact 
(as mentioned above), could actually be quite annoying. But for someone 
who is still new to gentoo.. it would be useful until they get a grasp 
on what USE flags do what.

Actually, I'd find it useful personally.
People add *weird* use flags sometimes.

Lack of feedback is partially the fact I'd rather see it as a class 
based approach; can tag it into the rewrite whenever UI work gets in 
full gear, but adding new features into stable that will have to be 
reimplemented in the rewrite doesn't seem wise (hence the feature 
freeze declaration).

LoL... yes, thats true.

A suggestion possibly to keep in mind is what if all functionality 
related to USE flags were somehow implemented in a seperate class/set of 
functions... or maybe that's already being done. But I mean, the job of 
determining which flags apply to what package and managing all that and 
how it works... I noticed that (at least in stable) a lot of it is in 
portage.config, but maybe it could be a seperate class that 
portage.config uses.. and other things (like deps, etc). Then stuff like 
outputting USE flags, or adding additional ways to determine which USE 
flags to actually use for each package, would all be in one location, 
lending itself to code reuse...

Of course, this is just from my looking at portage stable for a week or 
so... maybe its already being done. :)

It's being done :)
Essentially, you have this
config
domain
|--repo(s)
|  |--cache(s)
|  |--sync
|--vdb(s)
|--profile(s)

Domain is generated from configuration, as are all of the other 
objects; the config class just holds config data, and instantiates 
objects, shuffling them around dependant on an external file that 
states the rules for the config (in the process, stating how to 
instantiate the objs).

Config build data is domain data; your normal ebuild repository is an 
'unconfigured' repository, iow, you can toggle stuff on it to change 
the metadata of packages it returns.
The domain during instantiation notes that it has an unconfigured repo 
in it's list, inspects the repo instance for what is needed to 
configure it (and the func to call), calls the func with the 
configurables supplied, and uses the returned repo instead of the 
unconfigured repo.

Via this, the config data (USE, build, etc) is pushed down into the 
repo.  The configured repo wraps the unconfigured repo's returned 
packages with it's own wrapper that binds the config data into it, and 
hands that back.

Probably not a great description, but the short version is it works 
pretty well, and is pretty well encapsulated.

What I'd *like* to see is the use.{local.,}desc information bound into 
the repository, and have it supplied from the repository object; doing 
so keeps that data in the repo backend, not screwing up any 
abstractions that are carefully defined to allow for remote 
replacements.

Haven't proposed it to -dev yet, but I'd like to see package.* and 
use.* moved out of profiles/ , and into it's own base directory in the 
ebuild repository.
Reasoning is that profile objs are seperate from repo objs; the fs 
layout should reflect that to some degree.  It's cleaner anyways, imo.

[gentoo-portage-dev] Additional information to output: emerge -pv

[Dustin Spicuzza]

[-- Attachment #1: Type: text/plain, Size: 1732 bytes --]

Hey,

I've been using Gentoo for a couple of years now... and portage was the 
#1 reason I kept using Gentoo over other Linux distros... and why I'm 
still using it.

Something that's always bugged me a lot is USE flags. Which, while I 
think that they are one of the best things about portage, I think that 
they are also one of the more annoying features as well... it can be 
relatively annoying to configure it all up. Especially researching what 
they are... yes, it just takes a little bit of effort to find them, but 
why not make it slightly easier?

Anyways, I made a patch (against Portage 2.0.51.22-r2, attached as 
verbose_use_patch.tar) that adds the description of each USE flag to the 
'emerge -pv <package>' command. The output for openoffice, for example, 
looks something like this...

[ebuild  N    ] app-office/openoffice-1.1.4-r1  -curl -hardened -java 
+kde -nptl +zlib 215,331 kB
  *  curl - Adds support for client-side URL transfer library
  *  hardened - activate default security enhancements for toolchain 
(gcc, glibc, binutils)
  *  java - Adds support for Java
  *  kde - Adds support for kde-base/kde (K Desktop Enviroment)
  *  nptl - Enable support for Native POSIX Threads Library, the new 
threading module (requires linux-2.6 or better usually)
  *  zlib - Adds support for zlib (de)compression

And, it does this for each package (only for verbose obviously) Its a 
very small, non-invasive patch, and quite small (a routine in 
portage_util.py, and 5 lines of code in emerge). 

I attached the patch here because I wasn't quite sure of the proper 
procedure for patch submission... anyways, thanks for all your work! 
Hopefully in the future I can contribute to this project.

Does it repeat the same use flags over and over again for each package, 
or just explain it once? Also, does it distinguish local from global use 
flags? I didn't have a look at the code, but keep in mind that local use 
flags may have different meanings although they're used for more than 
one package.
Also, i (personally) don't like this feature, but i use -v *always*, so 
I suggest you make it only print the explanation if -pvv is given.

The appropriate way would be to open a bug in bugzilla, assign it to the 
portage team and attach  the patch there (normally each file separately, 
not packed in a tarball)

How about making it so you need two -v switchs (eg: -vv) to get the
long listing? I use `emerge world -puv` all the time and don 't want
to have to scroll through so much stuff.

Conflicts with -vv usage in >=2.1 which pulls from metadata, dumping 
maintainer/herd.

Correction, I'm wrong- that's emerge -sv I'm thinking about.

I like it but I'd like to see it in another tool.  Or in the case of 
HEAD, an emerge module.  I know it's a PITA right now because all the 
dependencies are depgraph related and it hasn't been easy to rip it 
out.  It would be nice to have a set of modules for generating metadata 
like this in script form for servers as opposed to some kind of weird 
emerge output that then needs some regex voodoo process.

Just my two cents :)
