Color Swatch Utility

Disclaimer

I'm in the middle of adding code that will ZIP the Procreate JSON format back into an archive so it doesn't full work with Procreate yet

Description

Some simple Swift 4 classes to convert a collection of colors to/from an Adobe ASE Swatch file, Procreate file or plain CSV file.

You can use this to read an Adobe ASE swatch file in and get a collection of the colors, and then write it back out to somethinglike Procreate JSON format or just CSV

Example

import Foundation

// read some data from a TXT file
let io:IOManager = IOManager(name: "Copic 358", ext:"txt");
let colors:[String] = io.readTxt();

// parse the lines
let csv:CSVManager = CSVManager();
if ( csv.read(lines: colors) > 0)
{ tester.printer(colors: csv.colors, groups: csv.groups); }

// create ASE manger and add everything
let ase:ASEManager = ASEManager();
ase.colors = csv.colors;
ase.groups = csv.groups;

// write to bytes
var bytes:Data = ase.write();

// write the ASE file
io.filename = "Copic 358";
io.ext = "ase";
let result:Bool = io.write(bytes);

// read the file back in
bytes = io.read();
let c = bytes.count

if ( ase.read(block: bytes) )
{ tester.printer(colors: ase.colors, groups: ase.groups); }

// write back the CSV data
csv.colors = ase.colors;
csv.groups = ase.groups;
let colors2:[String] = csv.write();
io.filename = "Copic Copy";
io.ext = "txt";
_ = io.write(colors2);

// create a Procreate manager of the same colors
let pro:ProcreateManager = ProcreateManager(colors: ase.colors);
pro.colors = ase.colors;
pro.groups = ase.groups;

let json:String = pro.write();
print(json);
