Escape sequences
|
||||
----------------
|
||||
Most text can contain escape sequences, that can for example color the text.
|
||||
There are a few exceptions: tab headers, dropdowns and vertical labels can't.
|
||||
The following functions provide escape sequences:
|
||||
* `core.get_color_escape_sequence(color)`:
|
||||
* `color` is a ColorString
|
||||
* The escape sequence sets the text color to `color`
|
||||
* `core.colorize(color, message)`:
|
||||
* Equivalent to:
|
||||
`core.get_color_escape_sequence(color) ..
|
||||
message ..
|
||||
core.get_color_escape_sequence("#ffffff")`
|
||||
* `color.get_background_escape_sequence(color)`
|
||||
* `color` is a ColorString
|
||||
* The escape sequence sets the background of the whole text element to
|
||||
`color`. Only defined for item descriptions and tooltips.
|
||||
|
||||
`ColorString`
|
||||
-------------
|
||||
`#RGB` defines a color in hexadecimal format.
|
||||
|
||||
`#RGBA` defines a color in hexadecimal format and alpha channel.
|
||||
|
||||
`#RRGGBB` defines a color in hexadecimal format.
|
||||
|
||||
`#RRGGBBAA` defines a color in hexadecimal format and alpha channel.
|
||||
|
||||
Named colors are also supported and are equivalent to
|
||||
[CSS Color Module Level 4](http://dev.w3.org/csswg/css-color/#named-colors).
|
||||
To specify the value of the alpha channel, append `#AA` to the end of the color name
|
||||
(e.g. `colorname#08`). For named colors the hexadecimal string representing the alpha
|
||||
value must (always) be two hexadecima
