pacgraph: Visualize your system

keenerd · 2009-04-29 18:35:58

It draws a pretty picture of your installed packages. Some examples:

a lightweight server
my primary computer
my old desktop

To try it yourself, get it from the AUR or get the code and run pacgraph. It will generate an SVG. If Inkscape or imagemagick is installed it will also render a PNG. It might seem a little slow, but it's many times faster than Graphviz.

Stuff supported from the command line:

Want to make only an SVG, no PNG?
-s --svg
Don't even want to render and SVG?
-c --console

Custom colors? Each of these takes one color, such as

pacgraph -b "#808080" -l "#ffffff"

-b --background
-l --link
-t --top
-d --dep

Font size can be set with

pacgraph -p 10 100

where the first number is the smallest point size, and the second is the largest.

By default optional dependencies are not counted towards a package. You can enable this with
-o --opt-deps

I think that may be the neatest thing to happen to Arch since Xyne

well put and i agree completely; Xyne should recode that to graphically show his interrelated arch contributions; should take him, what, like 7 minutes?

Interesting.

Is there a tool to permanently record application usage? Would be interesting a graph of apps used over a few months.

Xyne · 2009-04-29 19:24:59

@keenard
That's a very nice app. I had to modify the strip_info function at line 53 in pac_parse.py to handle metapackages without files in them (which lack %SIZE%). Here's the modified function:

def strip_info(info):
    keep = ['DEPENDS', 'OPTDEPENDS', 'PROVIDES', 'SIZE']
    info = dict((k.strip('%'),v) for k,v in info.iteritems())
    name = info['NAME'][0]
    info = dict((k,v) for k,v in info.iteritems() if k in keep)
    if not info.has_key('SIZE'):
      info['SIZE'] = 0
    else:
      info['SIZE'] = int(info['SIZE'][0], 10)
    return name, info

I'm not sure if that's the best way to do it (maybe 1 instead of 0, didn't check the output for the metapackages [edit]nvm, the metapackages are displayed[/edit]), but it got me past the error.

Also, could you please place both files in a dir named pacgraph inside the tarball? I really don't like it when an archive extracts multiple files to my cwd.

@Dusty & brisbin33

Isn't Xyne the coolest guy on the internet?

No that's Mr. Green.

@qubodup:
Cool, thanks! Though it looks like you got a bad roll of the RNG, usually it is more centered around the origin (almost always glibc).

Actually, fixed that. Tarball is updated. Should be more symmetrical now.

@Xyne
Patched the code (thanks) and corrected the tarball.

very nice, keenerd, can you explain how do you calculate weight of node in a graph?

Yannick_LM · 2009-04-29 21:01:17

Here's mine:

(Realizing I just got too much useless things here)
I'm actually not using gnome or kde anymore ...

Nice app, by the way. I tried to a bit of the same thing with dot, but results were quite ugly.

fijam · 2009-04-29 21:07:53

I have been thinking about such a tool for a week but lacked skill to write it! Thanks a bunch!

keenerd · 2009-04-29 21:09:57

@dodobas
The font weight is proportionate to the total size of a package. If a package has any unique dependencies, their sizes are absorbed into the parent. Basically, the size is the space freed by a "pacman -Rc".

Every now and then this dependency compression does weird stuff. In my desktop pacgraph, the OO spellcheck library is huge, because it depends on OO. Nothing else depends on OO, so OO's massive size is added to the small dictionary.

@Yannick_LM
Nice graph, the RNG gods must favor you :-)
It looks like Gnome and KDE clustered well, but your Python stuff is all over the map.

Realizing I just got too much useless things here

Originally this found packages not worth their diskspace.

I feel you pain with dot. I wasted a week before learning that dot is basically worthless when you have +100 nodes.

@fijam
You are welcome.

Gosh, my system is far messier than I realized it was... Time to go clean some unused packages out. Definitely not nexuiz, though.

Thanks for this awesome tool!

wow! that helped me to get rid of over 500mb in packages...
and what a brick that openoffice is!

smartboyathome · 2009-04-29 22:53:07

Should I uninstall some of the packages on my laptop?

qubodup · 2009-04-29 23:42:16

I tried the new 'version' -- with color changes.

nice, i like the dark look alot better

jordz · 2009-04-29 23:54:50

Tried it on my laptop, it just got a fresh install + gnome

I didn't know xmonad-contrib was so big.

This is an neat little gadget. I don't know of any better complement.

Holy —!

That is one big package you got there.

keenerd · 2009-04-30 01:06:47

Minor update, it now identifies the top level packages. Demo screenshots have been updated too.

Thanks all who are giving this a whirl. It appears that XFCE clumps up nicely, while Gnome grows outward very quickly. No idea why.

@qubodup
Some of the lines disappeared in your recoloring. I presume you used Gimp/select-by-color? Another option is to edit the svg file in a text editor. There are just four lines to set all the colors. Then you can re-render it with

inkscape -D -b "#ffffff" -e pac3.png pac3.svg

where "#ffffff" is the background color.

@Lexion
It isn't. But xmonad-contrib depends on xmonad depends on haskell. Chances are xmonad is the only haskell app you've got. Unshared dependencies are absorbed by their parent, so it's got the full weight of haskell counting against it. (That behavior could be changed, but it removes around 25% of the packages, making things that much easier to read.)

Next up, decent command line opts and throw it on the AUR.

koch · 2009-04-30 02:05:54

time to clean up

flowheat · 2009-04-30 02:36:28

Amusingly enough installing inkscape so i could produce the .png was the biggest package on my system

keenerd · 2009-04-30 02:53:09

flowheat, that is a tight installation you've got. I am impressed.

Might I recommend a two step process? Run pacgraph without inkscape. It will still make the SVG. Then install inkscape and punch in the render command.
