funtionzsh

First of all I'd like to apologize for the recent inactivity. I promise that I'll keep updating this blog as often as time allows.

Now, here is a simple function for extracting archives depending on their file type.

I did not write this function myself and all credit goes to Vincent, Milomouse.

# extract archive with preferred options:

function extr {

if [[ -f $1 ]]; then

case $1 in

*.tar.bz2) tar xjf $1 ;;

*.tar.gz) tar xzf $1 ;;

*.bz2) bunzip2 $1 ;;

*.rar) unrar x $1 ;;

*.gz) gunzip $1 ;;

*.tar) tar xf $1 ;;

*.tbz2) tar xjf $1 ;;

*.tgz) tar xzf $1 ;;

*.zip) unzip $1 ;;

*.Z) uncompress $1 ;;

*.7z) 7z x $1 ;;

*.xz) unxz -vk $1 ;;

*.lzma) unlzma -vk $1 ;;

*) print "'$1' cannot be extracted via extr()" ;;

esac

else

print "'$1' is not a valid file"

fi

}

Add the following to your .zshrc to be able to use the function:

(Don't forget to replace '.zsh' and 'funcs' with your own dir/filename)

# source external configuration files:

ZDOTDIR="${HOME}/.zsh"

for i in ${ZDOTDIR}/funcs; do

. $i || { print "$i: cannnot source file" }

done

All done! Whenever you wish to extract an archive just type "extr /path/to/archive" without the quotes ofcourse.

tmpwm

Ratpoison doesn't always handle windows/frames/applications the way I want it to. One example is mplayer playing files with a lower resolution than the actual screen which results in transparent borders around the player. To fix this i wrote a quick and dirty script in zsh that uses ratpoisons built in tmpwm-command to launch mplayer in another window manager.

The script is written with my folder hierarchy in mind so you might want to change the affected lines or you could add something like:

# Choose folder that contains videofolders

echo -e "vidfolder:\\n"

PS3='viddir: '

read VIDDIR

echo

And then replace the "~/media/video/" with $VIDDIR

The following script is nowhere near perfect so feel free to post improvments

#!/bin/zsh

## details: play mplayer videos in tmpwm

## depend: ratpoison + ls + mplayer

# Choose temporary WM. Must be a valid and installed WM

clear

echo -e "Enter tmpwm of choice:\\n"

PS3='wm: '

read WM

echo

# Select video folder from a list

echo -e "FOLDERS:\\n"

PS3='Select a folder: '

OLD_IFS=${IFS}; IFS="

"; select FOLDER in `ls ~/media/video`

do

OLD_IFS=${IFS}; IFS="

"; cd ~/media/video/$FOLDER

# Break, otherwise endless loop

break

done; IFS=${OLD_IFS}

echo

# Select a file in $FOLDER to play

echo -e "FILES:\\n"

PS3='Select a file: '

# Opens the selected file in Mplayer under $WM and kills the temporary wm when mplayer exits

select FILE in `ls ~/media/video/$FOLDER`

do

`ratpoison -c "tmpwm $WM" & mplayer -fs ~/media/video/$FOLDER/$FILE && killall $WM`

# Break, otherwise endless loop

break

done

exit 0

Ratmenu

I discovered ratmenu a while back and have been using it ever since.

Here's the script i use to launch it:

#!/bin/sh

ratmenu -font 6x12 -fg "#444" -align center -style dreary \

"ratpoisonrc" "ratpoison -c 'exec urxvt -e vim $HOME/.ratpoisonrc'" \

"ncmpcpp" "ratpoison -c 'exec urxvt -e ncmpcpp'" \

"mail" "ratpoison -c 'exec urxvt -e mutt'" \

"color" "ratpoison -c 'exec zenity --color-selection'" \

"top" "ratpoison -c 'echo $(top -b -n 1 | head -n 24)'" \

"battery" "ratpoison -c 'echo $(cat /proc/acpi/battery/BAT0/state)'" \

"dmesg" "ratpoison -c 'echo $(dmesg | tail)'" \

As this is a shell script it can be written on a single line or in multiple lines as above. If you decide to write it in multiple lines don't forget to separate them with backslashes so that the script is read by the shell as a single line. No backslash on the last line.

The first line is, of course, the shebang. The next line runs ratmenu with the fixed-medium-semicondensed font. I have the menu set up with gray text on a black background.

Lines 3 -9:

> Opens my ratpoison configuration file in vim for quick editing.

> Launches ncmpcpp (music player) in a terminal

> Launches mutt (mail client) in a terminal

> Uses zenity to display a colorpicker. I use this when editing my .Xdefaults and such.

> Pipes top (system information summary) to the ratpoison message area

> Pipes battery information to the ratpoison message area

> Prints the message buffer of the kernel in the ratpoison message area

I got my very first kernel panic today due to a failing harddrive. Luckily it did only hold my /home and I always keep backups so it was no biggie but I thought I'd share the info anyways.

Rodents be gone

I've been using the ratpoison wm for a while now. Thought I'd share a screen and my .ratpoisonrc.
