# NAME
f00bar-particles - configuration file

# DESCRIPTION

Particles are what renders the tags provided by modules. Each particle
defines its own set of configuration attributes. However, the
following attributes are supported by all particles:

[[ *Name*
:[ *Type*
:[ *Req*
:[ *Description*
|  left-margin
:  int
:  no
:  Space, in pixels, on the left side of the particle
|  right-margin
:  int
:  no
:  Space, in pixels, on the right side of the particle
|  margin
:  int
:  no
:  Short-hand for setting both _left-margin_ and _right-margin_
|  font
:  font
:  no
:  Font to use. Note that this is an inherited attribute; i.e. you can
   set it on e.g. a _list_ particle, and it will apply to all
   particles in the list.
|  foreground
:  color
:  no
:  Foreground (text) color. Just like _font_, this is an inherited attribute.
|  on-click
:  string
:  no
:  Command to execute when the particle is clicked. Note that the
   string is *not* executed in a shell.
|  deco
:  decoration
:  no
:  Decoration to apply to the particle. See *f00bar-decorations*(5)

# STRING

## DESCRIPTION

This is the most basic particle. It takes a format string, consisting
of free text mixed with tag specifiers.

## CONFIGURATION

[[ *Name*
:[ *Type*
:[ *Req*
:[ *Description*
|  text
:  string
:  yes
:  Format string. Tags are spcified with _{tag_name}_. Some tag types
   have suffixes that can be appended (e.g. _{tag_name:suffix}_). See
   *f00bar-modules*(5)).
|  max
:  int
:  no
:  Sets the rendered string's maximum length. If the final string's
   length exceeds this, the rendered string will be truncated, and
   "..."  will be appended. Note that the trailing "..." are
   *included* in the maximum length. I.e. if you set _max_ to '5', you
   will only get *2* characters from the string.

## EXAMPLES

```
content:
  string:
    text: "hello, this is footag's value: {footag}"
```

# EMPTY

## DESCRIPTION

This particle is a place-holder. While it does not render any tags,
margins and decortions are rendered.

## CONFIGURATION

None

## EXAMPLES

```
content:
  empty: {}
```

# LIST

## DESCRIPTION

This particle is a list (or sequence, if you like) of other
particles. It can be used to render e.g. _string_ particles with
different font and/or color formatting. Or ay other particle
combinations.

There is a short hand for this particle; instead of

```
content:
  list:
    items:
      - string: ...
      - string: ...
```

you can list the items directly:

```
content:
  - string: ...
  - string: ...
```

But note that this means you *cannot* set any attributes on the _list_
particle itself.

## CONFIGURATION

[[ *Name*
:[ *Type*
:[ *Req*
:[ *Description*
|  items
:  list
:  yes
:  List of sub particles
|  left-spacing
:  int
:  no
:  Space, in pixels, *between* the sub particles.
|  right-spacing
:  int
:  no
:  Space, in pixels, *between* the sub particles. Note: default=2
|  spacing
:  int
:  no
:  Short-hand for setting both _left-spacing_ and _right-spacing_

## EXAMPLES

```
content:
  list:
    spacing: 5
    items:
      - string: {text: hello}
      - string: {text: world}
```

# MAP

## DESCRIPTION

This particle maps the values of a specific tag to different
particles. In addition to explicit tag values, you can also specify a
default/fallback particle.

## CONFIGURATION

[[ *Name*
:[ *Type*
:[ *Req*
:[ *Description*
|  tag
:  string
:  yes
:  The tag (name of) which values should be mapped
|  values
:  associative array
:  yes
:  An associative array of tag values mapped to particles
|  default
:  particle
:  no
:  Default particle to use, when tag's value does not match any of the
   mapped values.

## EXAMPLES

```
content:
  map:
    tag: tag_name
    default:
      string:
        text: this is the default particle; the tag's value is now {tag_name}
    values:
      one_value:
        string:
          text: tag's value is now one_value
      another_value:
        string:
          text: tag's value is now another_value

```

# RAMP

## DESCRIPTION

This particle uses a range tag to index into an array of
particles. This can be used for example to map volume to a
volume-level icon, or a battery's capacity level to a battery
indicator.

## CONFIGURATION

[[ *Name*
:[ *Type*
:[ *Req*
:[ *Description*
|  tag
:  string
:  yes
:  The range tag (name of) to use as index
|  items
:  list
:  yes
:  List of particles. Note that the tag value is *not* used as-is; its
   minumum and maximum values are used to map the tag's range to the
   particle list's range.

## EXAMPLES

```
content:
  ramp:
    tag: capacity
    items:
      - string: {text: }
      - string: {text: }
      - string: {text: }
      - string: {text: }
      - string: {text: }
```
