[gentoo-user] introspection USE flag and KDE

[gentoo-user] introspection USE flag and KDE

[Dale]

Howdy,

I notice this USE flag is on by default now.  I also follow -dev but 
this still is not clear for me.  What exactly does introspection 
enable?  Is it some GUI thing or something else?  I also think I saw 
somewhere it is mostly a Gnome thing.  Do I need it since I only use KDE 
and have Fluxbox as a backup GUI?

Basically, should I disable this thing or let it run with it?  Not 
asking just for me but as a heads up for others as well.  Update list:

Might I add, the USE description seems worthless to me.  o_O

Here's what i do in that situation;
Goto http://www.gentoo.org/dyn/use-index.xml and find that the
complete name for introspection is gobject-introspection, so google
that and find https://live.gnome.org/GObjectIntrospection

Now ask someone who codes WTF that page means :) Sounds like it allows
programs to use code from different languages. Assume gentoo devs know
what they're doing, so accept their decision and stop thinking about
it.

Well, I did the euse -i thing, googled, and also read about it on -dev.  
It made no sense.

You give good advice tho.  I'm going to hit Y and let it update.

Thanks.

Re-reading what I wrote sounded a bit rude, so rephrased;

I didn't read it that way.  You have to be pretty blunt for me to take 
things the wrong way.  I always keep in mind that reading text can be 
done in several ways.  I try to always take it in a good way unless 
there is no good way to read it  If you call me a a**hole, well I would 
be offended.  ;-)   Then again, I have been called worse.  I have been 
called better to tho.  Anyway. .

I took that it wasn't going to add some HUGE amount of bloat and that 
even tho I don't use Gnome, it is OK to let it do its thing.  I did that 
and nothing blew up so far.  May blow up tomorrow tho.  lol

More specifically, while Gnome apps could already be written in
multiple languages, the libraries bridging those languages to C were
cumbersome (and thus buggy) to maintain, and this introspection change
is intended to result in a cleanup of that process.

Ohhh, now I see.  I thought it was talking about languages like English, 
Spanish etc.  lol

The ASCII-art on page [1] pretty much sums it up with regard to the
compile step:

There is a second compiler involved that parses the comments in the C
source code and generates binary files with type information etc. which
can then be used for language bindings.

So, it will probably slow down compilation and use more disk space (but
not very much, as stated on -dev). Also, as stated on -dev, ALWAYS
enable this unless you want to recompile most of @world if you ever need
a language binding.

Ahhhhh, pictures, well sort of anyway.  My biggest thing is I don't use 
Gnome.  It sounds like KDE may be moving this direction too.  So, may as 
well leave it alone.  I did read somewhere where the size increase is 
fairly small. I got a 160Gb drive for my OS so I think it will fit on 
there.  lol

Now I see better.  Thanks.
