foxify colors

[eylles]

This adds the ability to change colors with the pywalfox algorithm.

blocking:

• property export #13

unfortunately this is a time when once again i'm hitting face first into the wall that is #13

which means that it would only be possible to add colors modified like this as part of the special colors in the main color dict, not allow users to call the foxify property from a template as the way template export function is defined at:

pywal16/pywal/export.py

Lines 24 to 83 in ec2ad5a

	def template(colors, input_file, output_file=None):
	"""Read template file, substitute markers and
	save the file elsewhere."""
	# pylint: disable-msg=too-many-locals
	template_data = util.read_file_raw(input_file)
	for i, l in enumerate(template_data):
	for match in re.finditer(r"(?<=(?<!\{))(\{([^{}]+)\})(?=(?!\}))", l):
	# Get the color, and the functions associated with it
	cname, _, funcs = match.group(2).partition(".")
	# Check that functions are needed for this color
	if len(funcs) == 0:
	continue
	# Build up a string which will be replaced with the new color
	replace_str = cname
	# Color to be modified copied into new one
	new_color = util.Color(colors[cname].hex_color)
	# Execute each function to be done
	for func in filter(None, re.split(r"\)|\.", funcs)):
	# Get function name and arguments
	func = func.split("(")
	fname = func[0]
	if fname[0] == ".":
	fname = fname[1:]
	if not hasattr(new_color, fname):
	logging.error(
	"Syntax error in template file '%s' on line '%s'",
	input_file,
	i,
	)
	function = getattr(new_color, fname)
	# If the function is callable, call it
	if callable(function):
	if len(func) > 1:
	new_color = function(*func[1].split(","))
	else:
	new_color = function()
	# string to replace generated colors
	if func[0] != ".":
	replace_str += "."
	replace_str += "(".join(func) + ")"
	else:
	# if it is an attribute i.e. rgb
	replace_str += "." + fname
	new_color = function
	if isinstance(new_color, util.Color):
	new_color = new_color.strip
	# If replace the format placeholder with the new color
	if new_color is not colors[cname]:
	new_color = str(new_color)
	template_data[i] = l.replace("{" + replace_str + "}", new_color)
	try:
	template_data = "".join(template_data).format(**colors)
	except (ValueError, KeyError, AttributeError) as exc:
	logging.error(
	"Syntax error in template file '%s': %r.", input_file, exc
	)
	return
	util.save_file(template_data, output_file)

as a finditer and such careless reggular expression usage should have never been part of the function... but we are already past beyond that point...

anyway will have to leave this open until that problem is eventually fixed.

Since #187 was merged a few months ago, this should be unblocked.

Unless I'm missing something you should be able to just rebase this ontop of the current master and be good to go

[eylles]

yeh, there are other changes i want to do to this PR, will try to commit them today and merge

[eylles]

nevermind, changed ideas the further changes i wanted to make here will go to a different branch
