import re #To perform the search and replace.

from ..Script import Script

class switchMaterial(Script):
    """switch Material
    """

    def getSettingDataString(self):
        return """{
            "name": "switch material",
            "key": "switch_Material",
            "metadata": {},

            "settings":
            {
                "retraction":
                {
                    "label": "retraction",
                    "description": "Amount of retraction to get the previous filament out of the way",
                    "type": "float",
                    "default_value": "40.0"
                }
                "speed":
                {
                    "label": "speed",

                }
            }
        }"""

    def execute(self, data):
        retraction = self.getSettingDataString("retraction")
        speed = self.getSettingDataString("speed")
        pre_fix = "\nT"
        firstTime = True
        current_tool = 0
        last_position = 0
        text = ""
        for layer_number, layer in enumerate(data):
            for ocurrence in re.finditer(pre_fix,layer):
                current_tool = int(layer[ocurrence.end()])
                if firstTime:
                    firstTime = False
                    text = layer[:ocurrence.start()]
                    if current_tool == 1:
                        text += "T0\nM104 S{material_print_temperature, 0}\nM105\nM109 S{material_print_temperature, 0}\nM83\nG0 X0 Y0\nG0 E-%.2f F%i\nT1\n"%(retraction,speed)
                    last_position = ocurrence.end()
                else:

                        text = layer[:ocurrence.start()]
            data[layer_number] =  text #Replace all.
        return data
