 Posted: Thu Jul 27, 2006 3:03 am Post subject: Portage Utility: adduseflags |
 |
|
I've written a bash script to make managing the /etc/portage/package.use file easier. It's based in part on my earlier attempt at bash scripting, addkeywords (https://forums.gentoo.org/viewtopic-t-464213.html). This script also requires the program "eix" (in portage) to search for packages. This script searches the eix database for a package, then lists the USE flags and their descriptions, prompting you to add or remove flags.
Usage: adduseflags <package query>

This is a small bash script to easily add USE flags

the program "eix" (in portage) to search for packages.
Usage: adduseflags <package query>
To enable a USE flag, enter the flag name.
To disable a USE flag, enter the flag name preceeded by a "-".

Enter new flags: -arts visualization kde
will enable visualization and kde, and disable arts.

You could greatly reduce the complexity of these by just using "emerge" rather than eix.
http://68.111.181.40:9002/unmask.sh
Does the same thing as your addkeywords program. Though, it doesn't list all packages with similar names like eix.
But I prefer it that way. |

The following replaces everything from "preparing packages" to "choosing package" sections.
| Code: | finalpackage=`emerge $query --nodeps -qp|cut -c17-60| \
grep "/"|cut -f1 -d "["|sed 's/-[0-9].*//'`
if [ "$finalpackage" != "" ]
then
echo $finalpackage
else
echo "Sorry, no packages match the query." && exit 1
fi |
Note that after the = and at the end of the 2nd line, that is a back-tick (shift+tilda) and not an apostrophe. Otherwise, this won't work.
Also, I think it would be better to not use external files for storing use flags. They could be stored in a simple variable that is just a list of them.
That would keep the script more self-contained and would avoid having a useless temp directory. |

Changes I made:
1) No longer uses eix. Just uses emerge, which makes it much simpler (both to use and maintain).
2) No longer uses temp files. After I got rid of eix stuff, the only temp file was a single line of text that had the USE flag settings used. So I edited so that "uses" was no longer a file but just a string.
That's it. Nice job; I just felt like tweaking it. |

Nice job to both of you! For grins, I just tried it out and have two small suggestions to make:
Since you no longer use eix, you may want to:
- change the help text.
- Do something different for packages that match two or more entries in portage:
| Code: | $ adduseflags kopete
Sorry, no packages match the query.
$ emerge -pv kopete
These are the packages that would be merged, in order:
Calculating dependencies
!!! The short ebuild name "kopete" is ambiguous. Please specify
!!! one of the following fully-qualified ebuild names instead:
net-im/kopete
kde-base/kopete
|
Otherwise, again - nice job!

I'm glad someone found my script interesting/helpful.

I agree. However, being the newbie bash scripter that I am, I couldn't get the eix-related part to format correctly unless I stored some of the output in temp files. A lot of this code is re-used from my other script, addkeywords.
| Quote: | | Do something different for packages that match two or more entries in portage: |
This is handled nicely by eix (why I like it), but could also be handled by requiring the category name when specifying a package Or if you wanted to get more complicated, you could make an if-then statement to detect when there was ambiguity, and then choose.
| Quote: | | That's it. Nice job; I just felt like tweaking it. |
That's what makes open source great.
