[Slapt-get-user] Filter location and meta package

Hi Kocil,

>   ./x11/gtk/NET/dillo
>   ./x11/gtk2/NET/firefox
> 
> We want to able to filter, for example:

slapt-get --search './x11/gtk/'

> * only NET packages (get dillo and firefox, not xmms).

slapt-get --search './x11/.*?/NET'


Or you can group packages together using meta-packages.

Sure it is.  Makes it easy to identify which packages go with a specific flavour.  This makes
upgrades easier as well.  Your vector-soho package will be identified as being installed and
when upgraded will get the newest additions to that flavours package listing automatically.

You mean an automatic way to remove the meta packages requirements?  FYI, removing a meta
package will not remove it's requirements.

Most of all the unofficial slack packages available follow a convention of putting the
builder's tag after the build number.  So slapt-get has been designed to work with this.  If
you put vl after the 5 in your example, you will get the expected results.

> cdrtools-2.01-i486-1.tgz over cdrtools.1.10-i586-vl5.tgz

> That should not happen, since the older is BETTER.

In this case, you can add cdrtools to the excludes list, cdrtools$ then rename your cdrtools to
cdrtools-stable-1.10-i585-5vl.tgz.   You can also use slack-conflicts to specify cdrtools as
conflicting.

Hey, linuxpackages.net was the first! =]


take care,
