## 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`.

## TRANSLATING SAFE EYES
From version 1.1.0, Safe Eyes supports translation. Translation files for each langauges must be placed in `/opt/safeeyes/config/lang` directory. The language file name must follow [ISO 639-1](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) language code standard. For example, the language file of English must be `en.json`. Follow these steps to translate Safe Eyes to your language.
1. Copy `/opt/safeeyes/config/lang/en.json` to `/opt/safeeyes/config/lang/<iso-639-1-language-code>.json` (Please compare the `en.json` with the [online version](https://github.com/slgobinath/SafeEyes/tree/master/safeeyes/safeeyes/config/lang/en.json) before sending PR, because there can be new changes made to the language files)
2. Provide `language_name` in the language itself and `language_name_en` in English.
3. Translate other property values to the selected language.
4. Translate the comment in [safeeyes.desktop](https://github.com/slgobinath/SafeEyes/blob/master/safeeyes/share/applications/safeeyes.desktop) file.
**Note 1:** The `{}` used in property values will be replaced by runtime variables related to those commands. For example the `{}` in `Next break at {}` will be replaced by time at the runtime.
**Note 2:** Use Unicode when translating Safe Eyes.
**Note 3:** To change the language of Safe Eyes, select the language name from the combo-box in the Settings dialog.
For more details, have a look at existing language files: [lang](https://github.com/slgobinath/SafeEyes/tree/master/safeeyes/safeeyes/config/lang)
