PostPosted: Mon 10 Jan 2011, 19:48    Post subject: gui version  
I made a GUI version of this program, simplifying it a great deal
but it gives a visual message and a nice sound.
I call it PmusicTimer. I believe that this is the
first time that Pmusic has been used as a simple timer.
However Pmusic can be used with Pschedule to delay the playing
of a playlist.

Pmusic has the benefit that mp3 files can be used and
nearly all Puppies have pmusic built-in.

There is a bug that I found with the GUI. Only short sounds can
be used... but that isn't much of a problem since it
is to used as a simple alarm timer.

Here it is . Feel free to change it any way you want.
A nice loud sound file is included.

You might put the player outside the loop.

Code:


mflag=''
for ((i=0;i<=${x};i++)); do
n="$((${n} + 1))"
if [ "$n" == "${tsec}" ]; then
mflag="1"
break
fi
sleep 1
done

[ "$mflag" ] && pmusic ${dir}${snd} 2>/dev/null

Really cool to see that you build a gui Very Happy

Try to run pmusic as a standalone process:
Code:
pmusic -b  ${dir}${snd} 2>/dev/null &

PostPosted: Sat 15 Jan 2011, 14:08    Post subject: new countdown timer  
Here's the newest pet
http://www.datafilehost.com/download-e2c1fa85.html

I've given up trying to make pmusic into timer, especially
when I discovered that the current playlist vanishes after
running the timer, so I'll stick with aplay

Here's my most current try. It's only 25k uncompressed.
That's because I use 2barks.wav which is built into Puppy.
I've basically broken up the program into 2 parts.
One is called tm ------> the original cli program,
the other tmtimer ---> the GUI

They are stored in the same place, /usr/local/bin/

Here is the code for the GUI part

Code:
#! /bin/bash


export DIALOG='
 <vbox>
 <hbox> <text>  <label>    \n
 
                </label></text></hbox>
     
      <hbox>
      <text> 
     <label>  Enter number of minutes</label>
     </text>
       <entry>
         <variable>ENTRY</variable>
       </entry>
       </hbox>
       
         <hbox> <text>  <label>    \n
                </label></text></hbox>
 

     <hbox>
      <button>
        <label>Start</label>
        <input file>/usr/share/images/document-open-recent.png</input>
        <action>echo You pressed the exit button</action>
        <action type="exit">Exit by button</action>
      </button>
     <text>  <label> "                      " </label></text>     
    </hbox>

 <hbox> <text>  <label>    \n
 
                </label></text></hbox>
     

 </vbox>
'
     I=$IFS; IFS=""
     for STATEMENTS in  $(gtkdialog3 --geometry=+200+100 --program DIALOG); do
       eval $STATEMENTS       
     done
     

tm $ENTRY 
exit

Might as well allow seconds:
Code:

<label>  Enter number of minutes:seconds</label>


You could also have an entry box for sound

Code:

tm ${ENTRY} ${SND}

It wasn't too hard to include an option for selection of a sound file.
It just required a few extra lines of code.
Code:

                 
<frame Sound file>
<hbox>
   <text>
     <label>   /root/puppy-reference/audio/</label>
     </text>
       <entry>
    <default>2barks.wav</default>
    <variable>SND</variable>
  </entry>
</hbox>
</frame>


Here it is.

This is as far as I can take this project. Someone else will have to take it
over and add more features. A tray app to tell the remaining time
would be nice.

  while [ $secs -gt 0 ]
  do
    sleep 1 &
    printf "\r%02d:%02d:%02d" $((secs/3600)) $(( (secs/60)%60)) $((secs%60))
    secs=$(( $secs - 1 ))
    wait
  done
  echo
)

# format  hours: minutes :seconds
  countdown "00:02:00"

Running sleep in background with the wait command is clever.

edit: ran better with:

Code:

secs=$(( ${1:0} * 3600 + ${2:0} * 60 + ${3:0} ))
