Collection of common interactive command line user interfaces, based on Inquirer.js.

Born as a Inquirer.js clone, it shares part of the goals and philosophy.

So, Inquirer should ease the process of asking end user questions, parsing, validating answers, managing hierarchical prompts and providing error feedback.

You can download the python-inquirer code from GitHub or download the wheel from Pypi.

Python-inquirer supports mainly UNIX-based platforms (eq. Mac OS, Linux, etc.). Windows has experimental support, please let us know if there are any problems!

pip install inquirer

Documentation has been moved to magmax.org/python-inquirer.

But here you have a couple of usage examples:

import re

import inquirer
questions = [
  inquirer.Text('name', message="What's your name"),
  inquirer.Text('surname', message="What's your surname"),
  inquirer.Text('phone', message="What's your phone number",
                validate=lambda _, x: re.match('\+?\d[\d ]+\d', x),
                )
]
answers = inquirer.prompt(questions)

Like a Text question, but used for larger answers. It opens external text editor which is used to collect the answer.

The environment variables $VISUAL and $EDITOR, can be used to specify which editor should be used. If not present inquirer fallbacks to vim -> emacs -> nano in this order based on availability in the system.

External editor handling is done using great library python-editor.

Example:

import inquirer
questions = [
  inquirer.Editor('long_text', message="Provide long text")
]
answers = inquirer.prompt(questions)

Shows a list of choices, and allows the selection of one of them.

Example:

import inquirer
questions = [
  inquirer.List('size',
                message="What size do you need?",
                choices=['Jumbo', 'Large', 'Standard', 'Medium', 'Small', 'Micro'],
            ),
]
answers = inquirer.prompt(questions)

List questions can take one extra argument carousel=False. If set to true, the answers will rotate (back to first when pressing down on last choice, and down to last choice when pressing up on first choice)

Shows a list of choices, with multiple selection.

Example:

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

Checkbox questions can take one extra argument carousel=False. If set to true, the answers will rotate (back to first when pressing down on last choice, and down to last choice when pressing up on first choice)

Like Text question, but with builtin validations for working with paths.

Example:

import inquirer
questions = [
  inquirer.Path('log_file',
                 message="Where logs should be located?",
                 path_type=inquirer.Path.DIRECTORY,
                ),
]
answers = inquirer.prompt(questions)
