Linesman

Determine if a value is in-bounds

Gem Setup

gem install linesman

# Gemfile
gem 'linesman'

How Do I Use This Thing?

There's not really much to it. There is only one method: Linesman.within_bounds?

It takes an option hash and a block.

The options hash must contain at least one of the following:

• :exactly
• :min
• :max

The block should return a value that is comparable to the bounds specified in the options hash.

The method returns either true or false based on the given criteria.

Examples:

Linesman.within_bounds?(exactly: 1) {2 - 1} # => true

Linesman.within_bounds?(min: 1, max: 10) {1} # => true
Linesman.within_bounds?(min: 1) {0} # => false
Linesman.within_bounds?(max: 1) {0} # => true

Contributing

Do you use git-flow? I sure do. Please base anything you do off of the develop branch.

1. Fork it.
2. Perform some BDD magic. Seriously. Be testing.
3. Submit a pull request.

So, Uh, Why?

In short, I've been needing this exact functionality all over the place of late, and it was quick enough to just throw it together.
