range_dsl

range_dsl provides easy open range and ranges with complex conditions

example

You can write these code in class which includes RangeDsl or in object extend RangeDsl.

Now use it in irb.

$ irb
require 'rubygems'
require 'range_dsl'
include RangeDsl

For example, with greater_than_equal

gte(3).include?(1) # => false
gte(3).include?(3) # => true
gte(3).include?(4) # => true

with greater_than

gt(3).include?(1) # => false
gt(3).include?(3) # => false
gt(3).include?(4) # => true

You can use these operators:

  • gte, greater_than_equal

  • gt , greater_than

  • lte, less_than_equal

  • lt , less_than

  • eq , equal

  • neq, not_equal

  • not_be

And can use connection operator

  • &, and

  • |, or

  • all

  • any

For example, you can write “1, 2, or greater than equal 5” like following:

r = any(1, 2, gte(5))
r.include?(0) # => false
r.include?(1) # => true
r.include?(2) # => true
r.include?(3) # => false
r.include?(4) # => false
r.include?(5) # => true

Or you can write it like this:

r = any(1, 2) | gte(5)
r.include?(0) # => false
r.include?(1) # => true
r.include?(2) # => true
r.include?(3) # => false
r.include?(4) # => false
r.include?(5) # => true

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.
