Raw
ChooseColor.js
// Choose & insert/change color in RGB-format by standard color selection dialog
// supported short format of standard colors
// http://akelpad.sourceforge.net/forum/viewtopic.php?p=8611#8611
// http://outstanding.hmarka.net/akelpad/scripts/ChooseColor.js
// https://gist.github.com/Infocatcher/4632145
// Version: 1.8.1 (2013.08.26) Infocatcher (support for short color format like "#f80")
// Version: 1.8 (2013.01.25) Infocatcher (support for color names like "silver")
// Version: 1.7.1 (2012.09.14) VladSh (warning fixes by Lint)
// Version: 1.7 (2012.09.13) VladSh (bug fixes, added/changed variation of formats of input/output data)
// Version: 1.6.1 (2011.02.16) se7h (autoselect color under caret)
// Version: 1.5 (2011.02.01) VladSh (change; short format)
// Version: 1.4 (2011.01.26) VladSh (изменение выделенного цвета)
// Version: 1.3 (2011.01.18) © FeyFre
//
// Arguments:
// default - значения цветов, которые будут отображаться при открытии (при отсутствии выделенного текста); см. пример ниже
// lcase ([0 | без параметра] / 1) - возможность вывода результата в нижнем регистре
// place - куда помещать выводимый результат:
// • [0 | без параметра] - в окно редактирования (замена выделенного текста)
// • 1 - в буфер обмена
// • 2 - в поле диалога (InputBox)
//
// Examples:
// -"Insert color..." Call("Scripts::Main", 1, "ChooseColor.js") Icon("%a\AkelFiles\Plugs\Toolbar.dll", 30)
// -"Вставка цвета..." Call("Scripts::Main", 1, "ChooseColor.js", `-default="127 127 127"`) Icon("%a\AkelFiles\Plugs\Toolbar.dll", 30) //initial color values from se7h
//color values by default
