Generic characters handling

Maybe pacman could handle generic characters (like * or ?)  in package names with the "sync" option.

For example:
"pacman -S alsa*" would allow to install all packages with a name beginning with "alsa"
"pacman -S sdl*"
"pacman -S net-*"

It seems it already works with the "add" and "upgrade" options, but it does not work with the "remove" and "query" options.

Why not something like:
"pacman -Q sdl*" or "pacman -Q *sdl"
to find out every package installed with a name beginning with "sdl" or finishing with "sdl"

Why not allow this for "sync", "query" and "remove" operations?

Re: Generic characters handling

Well, here's how I do it:

$ cat > pacman.like
#!/bin/bash

for package in `pacman -Sl | sed 's:[a-z]* *([a-z,A-Z,0-9]*) *.*:1:' | sort -u | grep '^$1'`; do
    pacman --noconfirm -S $package
done
^D <-- (Ctrl-D to exit 'cat')

CAUTION: Note the single-quote right after the "for package in " is a back-tick (the key to the left of "1/!" and "2/@") -- argh! just cut and paste...

Then:

$ chmod 755 pacman.like

Without the "--noconfirm" this is what you will get, for example (as root user):

# ./pacman.like 'xs'
Targets: xsane-0.96-1
Total Package Size:   1.5 MB
Proceed with upgrade? [Y/n] n

Targets: xscorch-0.2.0-1
Total Package Size:   0.3 MB
Proceed with upgrade? [Y/n] n

:: xscreensaver-4.20-1: is up to date.  Upgrade anyway? [Y/n] n

Targets: xskat-4.0-1
Total Package Size:   0.1 MB
Proceed with upgrade? [Y/n] n

Targets: xsmbrowser-3.4.0-1
Total Package Size:   0.1 MB
Proceed with upgrade? [Y/n] n

Targets: xsnow-1.42-1
Total Package Size:   0.1 MB
Proceed with upgrade? [Y/n] n

Targets: icu-3.0-2 mono-1.0.6-1 xsp-1.0.5-1
Total Package Size:   18.3 MB
Proceed with upgrade? [Y/n] n

Re: Generic characters handling

Well, here's how I do it:

$ cat > pacman.like
#!/bin/bash

for package in `pacman -Sl | sed 's:[a-z]* *([a-z,A-Z,0-9]*) *.*:1:' | sort -u | grep '^$1'`; do
    pacman --noconfirm -S $package
done
^D <-- (Ctrl-D to exit 'cat')

hmmm how about:

#!/bin/bash

packages=""
for package in `pacman -Sl | sed 's:[a-z]* *([a-z,A-Z,0-9]*) *.*:1:' | grep '^$1'`; do
   packages="$packages $package"
done

pacman -S $packages

a) I removed the sort call, as that doesn't matter, it just makes it slower
b) combined packages in one string to run pacman -S on, allowing one to confirm if they want

Like it was so slow to begin with 

Also, did you test it?  The reason for the sort was pretty important.  Try just part of the code:

pacman -Sl | sed 's:[a-z]* *([a-z,A-Z,0-9]*) *.*:1:'

Did you notice all these?

("sort -u" creates a "unique" list...)

Nice option, though:

heh, I'm a glutton for that sort of stuff

("sort -u" creates a "unique" list...)

hmmm, `uniq` will do the same thing, without sorting the list...

Me, too -- from habbits formed writing interrupt-driven drivers :shock: (Very timing intensive.)

Yeah, but then it wouldn't run as slow...
