Add color for success and error messages #5
Description
Adding color to CLI messages would be helpful for users to distinguish between error, success, or normal messages. Let's attempt to implement this without using any additional dependencies initially; if that's not possible, we can explore and discuss the packages to use.
Here is my POC for the color message (tested on Mac's terminal and iterm):
import sys from typing import List, Union class Styles: RESET = "\033[0m" BOLD = "\033[1m" UNDERLINE = "\033[4m" ITALIC = "\033[3m" SELECTED = "\033[7m" BLACK = "\033[30m" GREY = "\33[90m" CYAN = "\033[96m" RED = "\033[91m" GREEN = "\033[92m" BLUE = "\033[34m" YELLOW = "\033[93m" MAGENTA = "\033[35m" WHITE = "\033[37m" class StyledText: def __init__(self, text: str, style: Union[str, List[str]]): self.text = text self.styles = style if isinstance(style, List) else [style] # creating styled text joined_styles = "".join(self.styles) self._styled_text = f"{joined_styles}{text}{Styles.RESET}" def __str__(self) -> str: return self._styled_text def __repr__(self) -> str: return self._styled_text sys.stdout.write(str(StyledText("I am red.\n", Styles.RED))) sys.stdout.write(str(StyledText("I am green.\n", Styles.GREEN))) sys.stdout.write(str(StyledText("I am underlined.\n", Styles.UNDERLINE))) sys.stdout.write( str(StyledText("I am italic and blue.\n", [Styles.UNDERLINE, Styles.BLUE])) ) sys.stdout.write( str(StyledText("I am yellow selected.\n", [Styles.SELECTED, Styles.YELLOW])) )Ref: https://stackoverflow.com/questions/287871/how-do-i-print-colored-text-to-the-terminal
