How to change Python inquirer checkbox's select / unselect symbol from X and o to Y and N respe-CodePudding

The sample script:

import os
import sys
from pprint import pprint
import yaml

sys.path.append(os.path.realpath("."))
import inquirer  # noqa

questions = [
    inquirer.Checkbox(
        "interests",
        message="What are you interested in?",
        choices=["Computers", "Books", "Science", "Nature", "Fantasy", "History"],
        default=["Computers", "Books"],
    ),
]

answers = inquirer.prompt(questions)

pprint(answers)
print(yaml.dump(answers))

produces:

[?] What are you interested in?: 
   X Computers
   o Books

How do I change "X" and "o" to "Y" and "N" respectively?

PS: It's pretty common knowledge that XOXO means "hugs and kisses", so it may not be appropriate in some working environments.

CodePudding user response：

You have to define Your new theme and pass it as a parameter to inquirer.prompt.

Here is modified code changing "X" to "Y" and "o" to "N":

import os
import sys
from pprint import pprint

import yaml
from inquirer.themes import Default

sys.path.append(os.path.realpath("."))
import inquirer  # noqa

questions = [
    inquirer.Checkbox(
        "interests",
        message="What are you interested in?",
        choices=["Computers", "Books", "Science", "Nature", "Fantasy", "History"],
        default=["Computers", "Books"],
    ),
]


class WorkplaceFriendlyTheme(Default):
    """Custom theme replacing X with Y and o with N"""

    def __init__(self):
        super().__init__()
        self.Checkbox.selected_icon = "Y"
        self.Checkbox.unselected_icon = "N"


answers = inquirer.prompt(questions, theme=WorkplaceFriendlyTheme())

pprint(answers)
print(yaml.dump(answers))
