i3-timer

A simple timer for the i3 window manager's status bar built for i3blocks.

Installation

go get github.com/claudiodangelis/i3-timer

Add these lines to the configuration file, which is usually located at ~/.i3blocks.conf:

[i3timer]
command=~/go/bin/i3-timer -alarm-command="notify-send 'i3-timer' 'Alarm Elapsed!'; play /usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga"
interval=10

Note: higher values for interval lead to poor timer accuracy.

Colors

The -colors flag enables colored output. The config parametermarkup=pango is required, for example:

[i3timer]
command=~/go/bin/i3-timer...
markup=pango
interval=10

Color Codes

Note: if pango markup is not rendered, for example the output is something like <span color="red">Timer: 5m0s</span>, you will need to set font pango:Monospace 10 to the bar section of the i3's configuration file.

Status label

Arguments

Usage

You can interact with the timer by clicking and/or using the scrollwheel.

If passed, the value of -alarm-command will be executed when the timer runs out. In the example above the value is notify-send 'i3-timer' 'Alarm Elapsed!'; play /usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga, which will pop up a notification on the top right corner of the screen and play a sound.

You can execute whatever program(s) you like.

Key Bindings

You can setup key bindings to start and stop the timer by using i3blocks' signaling feature. What you should do is to create 2 additional blocks with no interval property but set the proper signal value for the blocks, then set i3 configuration to bind the emission of the given signals to a keyboard shortcut.

The following example will bind the start of timer to Mod1+Shift+Control+k (which will emit, for example, signal 10) and the stop to Mod1+Shift+Control+l (which will emit, for example, signal 11). After emitting signal 10 or 11, both key shortcuts will emit signal 12 that will refresh the timer's "gui".

1. Create the main block to configure the timer in i3blocks configuration file:

   [i3timer]
   command=~/go/bin/i3-timer -alarm-command="notify-send 'i3-timer' 'Alarm Elapsed!'; play /usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga"
   interval=10
   signal=12
   

2. Create the "start timer" block in i3blocks configuration file

   [i3timer]
   command=~/go/bin/i3-timer -exec-start
   signal=10
   

3. Create the "stop timer" block in i3blocks configuration file

   [i3timer]
   command=~/go/bin/i3-timer -exec-stop
   signal=11
   

4. Create the keyboard shortcut binding in i3 configuration file

   # start timer
   bindsym --release Mod1+Shift+Control+k exec bash -c "pkill -SIGRTMIN+10 i3blocks && pkill -SIGRTMIN+12 i3blocks"
   # stop timer
   bindsym --release Mod1+Shift+Control+l exec bash -c "pkill -SIGRTMIN+11 i3blocks && pkill -SIGRTMIN+12 i3blocks"
   

5. Restart i3 and enjoy

Note: i3-timer stores timer's data into a hidden JSON file, .i3-timer.json stored at your home directory.
