range_dsl¶ ↑

range_dsl provides easy open range and ranges with complex conditions

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

• 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.
