This might look like a lot, but it really isn't once you look past the polyfills at the beginning and just look through the copyColorsToClipboard function. I took what you did and refactored it a bit:
Object.prototype.keys = function (obj) {
var keys = [];
for (var key in obj) keys.push(key);
return keys;
};
Array.prototype.map = function (callback) {
var mappedParam = [];
for (var i = 0; i < this.length; i++)
mappedParam.push(callback(this[i], i, this));
return mappedParam;
};
Array.prototype.indexOf = function (item) {
for (var i = 0; i < this.length; i++) if (this[i] == item) return i;
return -1;
};
Array.prototype.filter = function (callback) {
var filtered = [];
for (var i = 0; i < this.length; i++)
if (callback(this[i], i, this)) filtered.push(this[i]);
return filtered;
};
RGBColor.prototype.getString = CMYKColor.prototype.getString = SpotColor.prototype.getString = LabColor.prototype.getString = function () {
var result = this.typename.replace(/color$/i, "").toUpperCase() + "=";
var self = this; // Prevent namespace conflicts from scoping
if (this.spot) return this.spot.name
else result += Object.keys(self)
.filter(function (key) {
return !/typename|getString/.test(key);
})
.map(function (key) {
// Color keys are always in order, so just return them rounded:
return Math.round(self[key]);
})
.join(",");
return result;
};
function get(type, parent, deep) {
if (arguments.length == 1 || !parent) {
parent = app.activeDocument;
deep = true;
}
var result = [];
if (!parent[type]) return [];
for (var i = 0; i < parent[type].length; i++) {
result.push(parent[type][i]);
if (parent[type][i][type] && deep)
result = [].concat(result, get(type, parent[type][i], deep));
}
return result;
}
function setClipboard(str) {
var prev = get('selection');
selection = null;
var idoc = app.activeDocument;
var tlayer = idoc.layers.add();
var tframe = tlayer.textFrames.add();
// Had faulty unicode whitespace characters showing, so strip them:
tframe.contents = str.replace(/^\s*||\s*$/, "");
tframe.translate(10);
tframe.selected = true;
app.copy();
tlayer.remove();
app.selection = prev;
}
function copyColorsToClipboard() {
try {
// Get selection as real array instead of Array-like
var list = get("selection");
// Compile array of all fills and strokes
var colors = []
.concat(
list.map(function (item) {
return item.filled ? item.fillColor : null;
}),
list.map(function (item) {
return item.stroked ? item.strokeColor : null;
})
).filter(function (color) {
return !!color; // Remove any null values
}).map(function (color) {
return color.getString(); // Replace values with string in form [TYPE]=[VALUES]
}).filter(function (colorString, index, arr) {
return arr.indexOf(colorString) == index; // Remove duplicates
})
setClipboard(colors.join(", "))
} catch (err) {
alert(err);
}
}
copyColorsToClipboard();
In the above, these are identical colors in value but the left is a Spot color swatch named PMS 186 C whereas the right is a pure RGB.
