Parse yes/no like values

Useful for validating answers of a CLI prompt.


The following case-insensitive values are recognized:

'y', 'yes', 'true', true, '1', 1, 'n', 'no', 'false', false, '0', 0, 'on', 'off'

Enable lenient mode to gracefully handle typos.

Installation

Add this line to your application's Gemfile:

gem 'yn'

And then execute:

$ bundle

Or install it yourself as:

$ gem install yn

Usage

require 'yn'

Yn.parse('y')
# => true

Yn.parse('NO')
# => false

Yn.parse(true)
# => true

Yn.parse('abomasum')
# => nil

Yn.parse('abomasum', default: false)
# => false

Yn.parse('mo', lenient: true)
# => false

Unrecognized values return nil.

API

Yn.parse(input, options?)

input

Type: unknown

Value that should be converted.

options

Type: hash

lenient

Type: boolean
Default: false

Use a key distance-based score to leniently accept typos of yes and no.

default

Type: boolean
Default: nil

Default value if no match was found.

Development

After checking out the repo, run bin/setup to install dependencies, configure git hooks and create support files.

You can also run bin/console for an interactive prompt that will allow you to experiment.

The health and maintainability of the codebase is ensured through a set of Rake tasks to test, lint and audit the gem for security vulnerabilities and documentation:

rake bundle:audit          # Checks for vulnerable versions of gems 
rake qa                    # Test, lint and perform security and documentation audits
rake rubocop               # Lint the codebase with RuboCop
rake rubocop:auto_correct  # Auto-correct RuboCop offenses
rake spec                  # Run RSpec code examples
rake verify_measurements   # Verify that yardstick coverage is at least 100%
rake yard                  # Generate YARD Documentation
rake yard:junk             # Check the junk in your YARD Documentation
rake yardstick_measure     # Measure docs in lib/**/*.rb with yardstick
