CONFIGURING SAFE EYES

Just install and forget; Safe Eyes will take care of your eyes. To customize the basic preferences, go to Settings from Safe Eyes tray icon. If you need advanced features, you can manually edit the ~/.config/safeeyes/safeeyes.json for the following requirements:

Adding custom exercises

We're not going to pretend that the built-in list of exercises will be enough for everybody. So you can add your own! First, modify the custom_exercises property (which is an empty object by default) like so:

...
"custom_exercises": {
    "deep_breath": "Take a deep breath",
    "pushups": "Do ten push-ups",
    "other": "Other small things you should do on a regular basis"
}
...

Then add them to the short_breaks or long_breaks property as you see fit:

...
"short_breaks": [
    ...
    {
        "name": "deep_breath"
    },
    ...
],
...
"long_breaks": [
    ...
    {
        "name": "pushups"
    },
    ...
],
...

Override individual break time

Add the optional time property to the desired break with the required time parameter. The time unit is seconds. For example, to extend the break time of short_break_close_eyes to 30 seconds and the long_break_walk to 5 minutes (300 seconds), modify the configuration file as given below.

...
"short_breaks": [
    {
        "name": "short_break_close_eyes",
        "time": 30
    },
    {
        "name": "short_break_roll_eyes"
    },
    ...
],
...
"long_breaks": [
    {
        "name": "long_break_walk",
        "time": 300
    },
    {
        "name": "long_break_lean_back"
    }
]
...

Override audible alert after each break

Add the optional audible_alert property to the desired break with the required true/false parameter. For example, to disable audible alert for all breaks except the short_break_close_eyes, modify the configuration file as given below.

...
"audible_alert": false,
...
"short_breaks": [
    {
        "name": "short_break_close_eyes",
        "audible_alert": true
    },
    {
        "name": "short_break_roll_eyes"
    },
    ...
]
...

Customize disable time period

The default disable dor a given time options provide 30 minutes, 1 hour, 2 hours and 3 hours only. If you want to customize them or if you want to add/remove time based disable option, you can configure them in the safeeyes.json file. To add an additional Disable for 45 minutes, modify the configuration as shown below.

...
"disable_options": [
    {
        "label": "for_x_minutes",
        "time": 30,
        "unit": "minute"
    },
    {
        "label": "for_x_minutes",
        "time": 45,
        "unit": "minute"
    },
    {
        "label": "for_x_hour",
        "time": 1,
        "unit": "hour"
    }
    ...
]
...

NOTE: The unit can be one of these case-insensitive constants: second, seconds, minute, minutes, hour, hours

Skip or Take breaks based on the active window regardless of the full-screen mode

By default, Safe Eyes does not show the break screen if the current window is in fullscreen mode. However, you can override this feature by specifying the window-class of your interested applications.

For example, to take the break if your current window is Google Chrome regardless of the fullscreen mode, add google-chrome to take_break as given below:

...
"active_window_class": {
    "skip_break": [],
    "take_break": ["google-chrome"]
},
...

Similarly, you can skip the break even if your current application is in normal window state. For example, if you do not want to take a break while VLC player is in focus, add vlc to skip_break as shown here:

...
"active_window_class": {
    "skip_break": ["vlc"],
    "take_break": ["google-chrome"]
},
...

NOTE: The names vlc and google-chrome are not the application names but their window classes. Inorder to get the window class of an application, enter the following command in your terminal and click on the desired application. In the printed WM_CLASS, choose the second one.

xprop WM_CLASS

Some more sample window class names:

  • Mozilla Firefox: firefox
  • Sublime Text: sublime_text
  • Gnome Terminal: gnome-terminal
  • LibreOffice Writer: libreoffice-writer

Change the look and feel of the break screen

You can change the look and feel of the break screen in ~/.config/safeeyes/style/safeeyes_style.css.

Change the break image

Create a new directory resource in ~/.config/safeeyes

mkdir ~/.config/safeeyes/resource

Place your desired image in the resource folder. (Recommended size: 128x128 px). If the file name is same as the image name defined in ~/.config/safeeyes/safeeyes.json, that is it. Safe Eyes will load the image from ~/.config/safeeyes/resource directory. If the file name is different, edit the image name in ~/.config/safeeyes/safeeyes.json:

...
"short_breaks": [
    {
        "name": "short_break_close_eyes",
        "image": "image_file_name.png"
    }
    ...
]
...

Change the audible alert sound

Create a new directory resource in ~/.config/safeeyes

mkdir ~/.config/safeeyes/resource

Place the new alert.wav file in the ~/.config/safeeyes/resource directory.
