    11.04 timer-applet replacement?

    Anyone know of a possible replacement for the Gnome timer applet?

    Re: 11.04 timer-applet replacement?

    This is a really good app. I am not sure about Unity, but if you switch to ubuntu classic, which uses gnome 2, it's the same timer-applet. You can add timer from "Add to Panel".

    Btw, I don't think you can add applets in Unity since it incorporates menus on top. Correct me if I am wrong. I will stick with classic gnome2 until unity gets more functionality.

    Re: 11.04 timer-applet replacement?

    I searched for hours and couldn't find anything.
    The only suitable thing I found was a script that outputs a count down to conky.

    I managed to make a launcher, which uses the script, with presets that play a sound and send a notification when the timer is up.
    You have to create a .desktop file and, install/setup conky.
    It's a pretty long winded process to describe so if you can be bothered doing this
    I will post how to.

    Hmm. I already tend to use Conky, and have created .desktop files before to make things searchable in Gnome-Do/Dash, so I wouldn't mind so much. If you have the chance I would interested to see how you managed it

    I'm just on my way out.
    I'll post the .desktop and countdown script and get back to you.

    ***Note***
    The countdown script requires you have a ~/tmp folder.
    Create a tmp folder in your home directory if you don't have one.
    You need to install libnotify-bin for notify-send to work.
    Remember to change all the paths and make the script executable.


    Save this as countdown.sh and make executable.
    Saving in ~/scripts makes it easier when changing the paths in ConkyTimer.desktop
    Code:
    #!/bin/bash
    #
    # countdown script 
    # usage example: countdown.sh 00:10:00
    # starts a 10min countdown and write the status to $COUNTDOWNFILE 
    # (where conky is listening and displays the content in this setup)
    #
    # timer for teh perfect pizza
    # 
    
      IFS=:
      OUTPUTFILE=$HOME/tmp/countdown
      COUNTDOWNSOUND=$HOME/Sounds/bell.wav
      
      time=$1
      if [ -z "$1" ]; then
        time=$(zenity --entry --text "How long?" --entry-text "00:00:00" --title "zeh countdowwn");
      fi
    
     
     
      if [ -n "$time" ] && [ "$time" != "00:00:00" ]; then
        set -- $time
        secs=$(( ${1#0} * 3600 + ${2#0} * 60 + ${3#0} ))
        while [ $secs -gt 0 ]
        do
          sleep 1 &
          printf "%02d:%02d:%02d\n" $((secs/3600)) $(( (secs/60)%60)) $((secs%60)) > $OUTPUTFILE
          secs=$(( $secs - 1 ))
          wait
        done
        echo "00:00:00" > $OUTPUTFILE
        notify-send -u critical -i /home/glen/Pictures/Bell.png "ConkyTimer" "Times Up" &
        aplay -q $COUNTDOWNSOUND
        rm $OUTPUTFILE  
        echo
      fi

    Save this as ConkyTimer.desktop to your home folder.
    To edit this file to show your own presets and correct paths, enter in the terminal gedit ~/ConkyTimer.desktop
    Once edited drag and drop on the launcher.

    Clicking the launcher runs countdown.sh and you will get a popup
    to input a countdown in the form of HH:MM:SS

    Right clicking and choosing a preset runs countdown.sh HH:MM:SS
    eg the 3 min preset runs countdown.sh 00:03:00



    The line for conky (The timer only shows when running.ie ~/tmp/countdown exists)
    Code:
    ${if_existing /home/glen/tmp/countdown}${voffset 2}${font StyleBats:size=10}${color2}o${voffset -2}${font LCDMono:bold:size=12} Timer: ${color yellow}${exec tail -n1 ~/tmp/countdown}${endif}
    Goodluck

    Something else I just discovered.
    If you use own_window_type override in your conky config

    Re: 11.04 timer-applet replacement?

    This conky uses a lua script to show a cpu usage bar,
    the timer when active, cpu temp and download speed.

    You need the conky-all package with extra compiled features to use with lua.

    Save as bargraph_small.lua in ~/conky
    Code:
    --[[ BARGRAPH WIDGET
    	v2.1 by wlourf (07 Jan. 2011)
    	this widget draws a bargraph with different effects 
    	http://u-scripts.blogspot.com/2010/07/bargraph-widget.html
    	
    To call the script in a conky, use, before TEXT
    	lua_load /path/to/the/script/bargraph.lua
    	lua_draw_hook_pre main_rings
    and add one line (blank or not) after TEXT
    
    	
    Parameters are :
    3 parameters are mandatory
    name	- the name of the conky variable to display, for example for {$cpu cpu0}, just write name="cpu"
    arg		- the argument of the above variable, for example for {$cpu cpu0}, just write arg="cpu0"
    		  arg can be a numerical value if name=""
    max		- the maximum value the above variable can reach, for example, for {$cpu cpu0}, just write max=100
    	
    Optional parameters:
    x,y		- coordinates of the starting point of the bar, default = middle of the conky window
    cap		- end of cap line, ossibles values are r,b,s (for round, butt, square), default="b"
    		  http://www.cairographics.org/samples/set_line_cap/
    angle	- angle of rotation of the bar in degress, default = 0 (i.e. a vertical bar)
    		  set to 90 for an horizontal bar
    skew_x	- skew bar around x axis, default = 0
    skew_y	- skew bar around y axis, default = 0
    blocks  - number of blocks to display for a bar (values >0) , default= 10
    height	- height of a block, default=10 pixels
    width	- width of a block, default=20 pixels
    space	- space between 2 blocks, default=2 pixels
    angle_bar	- this angle is used to draw a bar on a circular way (ok, this is no more a bar !) default=0
    radius		- for cicular bars, internal radius, default=0
    			  with radius, parameter width has no more effect.
    
    Colours below are defined into braces {colour in hexadecimal, alpha}
    fg_colour	- colour of a block ON, default= {0x00FF00,1}
    bg_colour	- colour of a block OFF, default = {0x00FF00,0.5}
    alarm		- threshold, values after this threshold will use alarm_colour colour , default=max
    alarm_colour - colour of a block greater than alarm, default=fg_colour
    smooth		- (true or false), create a gradient from fg_colour to bg_colour, default=false 
    mid_colour	- colours to add to gradient, with this syntax {position into the gradient (0 to1), colour hexa, alpha}
    			  for example, this table {{0.25,0xff0000,1},{0.5,0x00ff00,1},{0.75,0x0000ff,1}} will add
    			  3 colurs to gradient created by fg_colour and alarm_colour, default=no mid_colour
    led_effect	- add LED effects to each block, default=no led_effect
    			  if smooth=true, led_effect is not used
    			  possibles values : "r","a","e" for radial, parallelel, perdendicular to the bar (just try!)
    			  led_effect has to be used with theses colours :
    fg_led		- middle colour of a block ON, default = fg_colour
    bg_led		- middle colour of a block OFF, default = bg_colour
    alarm_led	- middle colour of a block > ALARM,  default = alarm_colour
    
    reflection parameters, not avaimable for circular bars
    reflection_alpha    - add a reflection effect (values from 0 to 1) default = 0 = no reflection
                          other values = starting opacity
    reflection_scale    - scale of the reflection (default = 1 = height of text)
    reflection_length   - length of reflection, define where the opacity will be set to zero
    					  calues from 0 to 1, default =1
    reflection			- position of reflection, relative to a vertical bar, default="b"
    					  possibles values are : "b","t","l","r" for bottom, top, left, right
    draw_me     - if set to false, text is not drawn (default = true or 1)
                  it can be used with a conky string, if the string returns 1, the text is drawn :
                  example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",
    
    v1.0 (10 Feb. 2010) original release
    v1.1 (13 Feb. 2010) numeric values can be passed instead conky stats with parameters name="", arg = numeric_value	
    v1.2 (28 Feb. 2010) just renamed the widget to bargraph
    v1.3 (03 Mar. 2010) added parameters radius & angle_bar to draw the bar in a circular way
    v2.0 (12 Jul. 2010) rewrite script + add reflection effects and parameters are now set into tables
    v2.1 (07 Jan. 2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"

    Meanwhile this has popped up which looks nice and works with Unity:

    Nice find.
    Yes looks promising needs an alarm sound though.
    Prefer my botch job at the moment as I can see exactly how much time is left when working in maximized windows.

    Re: 11.04 timer-applet replacement?

    Hi,

    I've tried your program and works, but I can't make it work with conky to see the passing time on the top panel.
    I'm using precise.
    I've copied the conky config you say to the file /etc/conky/conky.conf
    Any idea? How can I activate conky?

    Thanks in advance
