C++ Inquirer

A single header C++11 library for interactive command line prompts.

Use

Simply include the header:

#include "inquirer.h"

And initialise the inquirer object (with optional title):

auto inquirer = alx::Inquirer("cpp-inquirer example");

To get the answers back, call inquirer.answer("some key"); with the key of your question. You will get a std::string as a value, so you will need to convert it to an approapriate type yourself.

I'm more than happy to accept pull requests with some minor requirements:

• Prefix your commit messages with a relevant change type. If the commit relates to a GitHub issue, include the issue number in the message. Example:

This addresses issue #123

or

Answers: added a way to return an answer with the correct type

• Please follow the naming convention already established in the code. There is no clangformat, but I'm sure you can deduce it yourself.
