Using dmenu to load extensions

[coreplayer2]

Hmmm

well this works for me so I think you can ditch the ugly sed  :p

Code: [Select]

for f in /usr/local/tce.installed/* ; do echo ":: ${f##*/}"; done | sort -bf


Code: [Select]

:: squashfs-tools
:: sstrip
:: submitqc
:: ttf-bitstream-vera
:: udev-extra
:: udev-lib
:: usbutils
:: wbar
:: wget
:: xdg-utils
:: Xlibs
:: Xorg-7.7-lib
:: Xprogs
:: Xvesa
:: xzgv
:: zsync

Which I think is the objective..?

[Misalf]

Thanks but nope. The main objective is to show a list of loadable extensions to choose from. In addition, instead of leaving out those already loaded, show them too but with some kind of indication (f.e. "::").
This is especially helpful for checking if a certain extension is loaded without having to know if it is present.
Then, for readability and my personal preference, the list should be sorted like humans do.
Not:
:: X.tcz
:: a.tcz
:: b.tcz
:: z.tcz
c.tcz
x.tcz
y.tcz

But:
:: a.tcz
:: b.tcz
c.tcz
:: X.tcz
x.tcz
y.tcz
:: z.tcz

If I could get  sort  to ignore ":: " that would certainly be preferable over the additional  sed . But meh.. couldn't get it to work. Anyway, the script doesn't behave like a sprinting snail anymore. Doing a little extra work 500 times is way faster than 500*500 times. q:

Still, if you can think of anything to bump me in the right direction, I'd be the last who complains.

Anything like this ?
"view info.lst and display already downloaded + loaded extentions" http://forum.tinycorelinux.net/index.php/topic,13056.msg71819.html#msg71819

show a list of loadable extensions to choose from. In addition, instead of leaving out those already loaded, show them too but with some kind of indication (f.e. "::").

Interesting. I'm happy with my dmenu script now but an additional dmenu apps browser might be nice. Thanks.

Please don't misunderstand, I luv sed.  Sed is awesome but I've found there are much faster methods in repetitive tasks

Let me to give a hint,  use sort earlier.. :p

Though I didn't time it, this executed really fast

Code: [Select]

cd /etc/sysconfig/tcedir/optional
tczs=$(ls *.tcz | sort -bf)
for f in $tczs ; do [ -e "/usr/local/tce.installed/${f%.*}" ] && echo ":: $f" || echo "$f"; done


Of course I had to test the theory

Code: [Select]

:: unzip.tcz
...
v4l-dvb-4.2.7-tinycore64.tcz
vlc.tcz
:: wbar.tcz
:: webkitgtk4.tcz
wget.tcz
wireless-4.2.7-tinycore64.tcz
wireless_tools.tcz
wpa_supplicant-dbus.tcz
x264.tcz
:: xcursor-themes.tcz
:: xf86-input-evdev.tcz
:: xf86-video-vesa.tcz
Xfbdev.tcz
:: xkeyboard-config.tcz
:: Xlibs.tcz
:: Xorg-7.7-3d.tcz
:: Xorg-7.7-bin.tcz
:: Xorg-7.7-lib.tcz
:: Xorg-7.7.tcz
:: Xorg-fonts.tcz
:: xorg-server.tcz
:: Xprogs.tcz
:: zip.tcz

[Misalf]

First, I'm sure I'm not misunderstanding you. Tools like sed are great but the less tools the better.
Second, I luv you. You made sed obsolete for me. (: time shows the same results but the code is looking faster. (;

Hey mocore, thanks! I've implemented downloading and parsing info.lst .

Using "+" (plus sign) to indicate downloadable extensions is not a good idea - those characters get removed from the string before it's shipped to  tce-load  but there are actually extensions that have a "+" in their file name (f.e. dvd+rw-tools.tcz). Now using "<".
