 * @scrollbar
 * @window
 * @separator
 * @listview
 * @box

## Name

Name: Internal name of the widget.

Sub-widgets are {Parent}.{Child}.

Example: listview, listview.element, listview.scrollbar

Names are prefixed with a `#`

List of names in **rofi**:

 * `#window`
 * `#mainbox`
   * `#mainbox.box`: The main vertical @box
 * `#inputbar`
   * `#inputbar.box`: The horizontal @box packing the widgets.
   * `#inputbar.separator`: The separator under/above the inputbar.
   * `#inputbar.case-indicator`: The case/sort indicator @textbox
   * `#inputbar.prompt`: The prompt @textbox
   * `#inputbar.entry`: The main entry @textbox
 * `#listview`
    * `#listview.scrollbar`: The listview scrollbar
    * `#listview.element`: The entries in the listview

## State

State: State of widget

Optional flag(s) indicating state.

These are appended after the name or class of the widget.

`@textbox selected.normal { }`

`#listview.element selected.urgent { }`

Currently only the @entrybox has states:

`{visible modifier}.{state}`

Where `visible modifier` can be:
 * normal: No modification.
 * selected: The entry is selected/highlighted by user.
 * alternate: The entry is at an alternating row. (uneven row)

Where `state` is:
 * normal: No modification.
 * urgent: This entry is marked urgent.
 * activE: This entry is marked active.

These can be mixed.

Example:
```
@textbox selected.active {
    background: #003642;
    foreground: #008ed4;
}
```

Sets all selected textboxes marked active to the given foreground and background color.

# File structure

The file is structured as follows

```
/* Global properties, that apply as default to all widgets. */
{list of properties}

@{class} {optional state} {
    {list of properties}
}
@{name}.{name} {optional state} {
    {list of properties}
}
```

The global properties an freeĺy be mixed between entries.

Each property is constructed like:
```
{key} : {value} ;
```
Key is a simple ascii string.
Separated from value by a colon ':';
Value supports the following formats:

 * string:  `"{string}"`
 * integer: `[0-9]+`
 * double:  `[0-9]+\.[0-9]`
 * boolean: `true|false`
 * color:
    * `#[0-9a-fA-F]{6}`: hexidecimal rgb color.
    * `#[0-9a-fA-F]{8}`:  hexidecimal argb color.
    * `argb:[0-0a-fA-F]{8}`: Old **rofi** argb color style.
    * `rgba\([0-9]{1,3},[0-9]{1,3}, [0-9]{1,3}, {double}\)`: css style rgba color.
    * `rgb\([0-9]{1,3},[0-9]{1,3}, [0-9]{1,3}\)`: css style rgb color.

Each property is closed by a semi-colon `;`;

The following properties are currently supports:

 * window:
    * font:            string
    * background:      color
    * foreground:      color

## Resolving properties


Current matching does:

 1. Find exact name match, with exact state match.

    If found return

 1. Find exact class match, with exact state match.

    If found return

 1. Find fuzzy name match, with fuzzy state.

    If found is not root node, return

 1. Find fuzzy class match, with fuzzy state.

    return
